1.2.4 マスターバッチの動作原理

マスターバッチの動作原理は、キャリア内に高濃度の顔料を均一に分散させることに基づいています。. プラスチック製品の加工中に, 少量のマスターバッチ (いつもの 1%-5%) 無色のプラスチック原料が混合されています. 押出成形または射出成形中の高温およびせん断力の作用下, マスターバッチのキャリアが溶解し、目的のプラスチック原料と混合します。, 均一に分散された顔料が放出され、ターゲットのプラスチックマトリックスに均一に分散されます。, これにより、プラスチック製品の着色という目的が達成されます。. このプロセスの鍵は、マスターバッチ内の顔料が凝集せずに均一に分散する必要があることです。, そうしないと色斑の原因になります, カラー製品の色の違いやその他の欠陥.

2. マスターバッチのコア加工技術: 二軸押出技術

マスターバッチ処理には主に混合が含まれます, 押し出し, 冷却, 造粒およびその他のプロセス, 中でも二軸押出技術はマスターバッチ混合と造粒の中核技術です. 単軸押出技術との比較, 二軸押出技術には強力な混合分散能力という利点があります。, 正確な温度制御, 短い滞在時間, 生産効率が高く、原料への適応力が高い, which can effectively solve the key problems of masterbatch processing (such as pigment agglomeration, uneven mixing, low production efficiency) and ensure the quality of masterbatch products.

Masterbatch mixing is one of the main applications of twin-screw extruders. The quality of masterbatch is directly determined by the performance of the twin-screw extruder and the rationality of the processing process. The key requirements of masterbatch processing for twin-screw extruders are: strong mixing and dispersing effect (to ensure uniform dispersion of pigments), 正確な温度制御 (to avoid pigment decomposition and carrier degradation), appropriate shear force (to break pigment agglomerates without damaging pigment particles), 高い生産効率 (to meet mass production needs) and good wear resistance (to adapt to the wear of high-hardness pigments such as titanium dioxide and carbon black).

2.1 Processing Difficulties of Masterbatch and Requirements for Extrusion Equipment

Although twin-screw extrusion technology is suitable for masterbatch processing, due to the particularity of masterbatch composition (high pigment content, easy agglomeration of pigments) and processing requirements (均一分散, 安定したパフォーマンス), there are still many difficulties in actual processing. The main processing difficulties and corresponding requirements for extrusion equipment are as follows:

2.1.1 Pigment Agglomeration and Poor Dispersibility

Pigments (especially inorganic pigments such as titanium dioxide and carbon black) have strong polarity and large specific surface area, which are easy to agglomerate into large particles during storage and mixing. 押出加工時に凝集物を完全に破壊して分散できない場合, マスターバッチの分散性が悪くなります, 着色されたプラスチック製品には色斑が発生します, 色スジ・色ムラ, 製品の品質に重大な影響を与える可能性があります. これはマスターバッチ処理における最も一般的かつ重要な問題です。.

このため、押出装置には強力な混合分散能力と適切なせん断力が必要です。. 二軸押出機は噛み合い共回転構造を採用する必要があります, スクリューには、回転中に強力なせん断力と混練力を発生させるのに十分な混合要素とせん断要素が装備されている必要があります。, 顔料の凝集を完全に破壊し、顔料をキャリア内に均一に分散させることができます。. 加えて, the screw speed and extrusion pressure should be adjustable to adapt to different types of pigments and masterbatch concentrations.

2.1.2 Pigment Decomposition and Carrier Degradation Caused by Overheating

Most pigments (especially organic pigments) have poor heat resistance, and the carrier (PEなど, PP) also has a certain temperature resistance limit. If the extrusion temperature is too high or the residence time of the material in the extruder is too long, the pigment will decompose (resulting in color fading, 変色), and the carrier will degrade (resulting in reduced mechanical properties of the masterbatch). This is another key difficulty in masterbatch processing.

This requires the extrusion equipment to have precise temperature control capacity and short residence time. The barrel of the extruder should be divided into multiple temperature control sections, and the temperature of each section should be precisely controlled within the optimal range (usually 150-220℃ for ordinary masterbatch, 200-280℃ for engineering plastic masterbatch), with a temperature control precision of ±1℃. The screw structure should be optimized to shorten the residence time of the material in the extruder (いつもの 1-3 分), avoiding long-term contact between the material and high temperature.

2.1.3 Wear of Screw and Barrel Caused by High-Hardness Pigments

Inorganic pigments such as titanium dioxide and carbon black have high hardness (Mohs hardness 5-7), which will cause serious wear to the screw and barrel of the extruder during extrusion processing. スクリューやバレルの耐摩耗性が悪い場合, すぐに着られてしまいます, resulting in reduced shear force and mixing capacity of the extruder, affecting the dispersibility of the masterbatch and reducing the service life of the equipment.

そのためには、押出機のスクリューとバレルが高品質の耐摩耗性材料で作られ、高度な製造技術で加工される必要があります。. 例えば, the screw and barrel can be made of imported wear-resistant alloy steel, バイメタル複合処理またはレーザークラッディング処理を受ける, which can greatly improve the wear resistance and corrosion resistance of the screw and barrel, and adapt to the processing of masterbatch with high-hardness pigments.

2.1.4 Instability of Product Quality Between Batches

Masterbatch processing requires strict control of various parameters (such as formula ratio, 混合時間, extrusion temperature, スクリュー速度, 送り速度). If the parameters fluctuate, the quality of the masterbatch (such as concentration, 分散性, tinting strength) will be unstable, resulting in color difference between batches of colored products, which will affect the reputation of the manufacturer.

This requires the extrusion equipment to have intelligent control capacity and stable performance. The extruder should be equipped with a PLC intelligent control system, which can realize precise control of feeding speed, スクリュー速度, extrusion temperature and other parameters, and store multiple sets of formula parameters. When producing different batches of masterbatch, only the corresponding parameters need to be called, avoiding repeated debugging, ensuring the stability of product quality between batches.

2.1.5 High Requirements on Processing Fluidity

Masterbatch has high pigment content, which will reduce the processing fluidity of the material. If the processing fluidity is too poor, the material will be difficult to convey and extrude, resulting in low production efficiency, unstable extrusion pressure and even equipment blockage.

This requires the extrusion equipment to have strong conveying capacity and adjustable shear force. The twin-screw extruder should adopt a reasonable screw pitch, lead and compression ratio design, and the screw should be equipped with sufficient conveying elements to ensure the smooth conveying of materials. 加えて, the extrusion temperature can be appropriately adjusted to improve the processing fluidity of the material, and lubricants can be added to reduce the friction between materials.

2.2 Working Principle and Process Flow of Masterbatch Twin-Screw Extrusion

The twin-screw extrusion process of masterbatch is a complex physical mixing process, which mainly includes raw material pretreatment, premixing, 餌やり, 溶融, mixing and shearing, 押し出し, 冷却, 造粒, screening and packaging. The core purpose is to uniformly disperse pigments, carriers and additives to form high-quality masterbatch granules. The specific working principle and process flow are as follows:

2.2.1 Raw Material Pretreatment

Raw material pretreatment is the foundation of masterbatch extrusion processing, which directly affects the mixing effect and product quality. The raw materials of masterbatch mainly include pigments/dyes, キャリア, 添加物 (dispersants, 相溶化剤, heat stabilizers, 等). The pretreatment steps are as follows:

Drying Treatment: Some pigments (such as organic pigments) and carriers (PAなど, ペット) 吸水性が高い. If the moisture content is too high, it will cause bubbles, agglomeration and other defects in the masterbatch during extrusion processing, and even cause hydrolytic degradation of the carrier. したがって, the raw materials must be dried before processing. The drying temperature and time are determined according to the type of raw material: 例えば, organic pigments are dried at 60-80℃ for 2-4 時間, PE/PP carriers are dried at 80-100℃ for 3-5 時間, and PA carriers are dried at 100-120℃ for 6-8 時間. The moisture content of the dried raw materials should be controlled below 0.1%.
Crushing and Sieving: For pigments with large particle size (such as titanium dioxide agglomerates) and carriers with uneven particle size, crushing and sieving treatment should be carried out to ensure the uniformity of raw materials. The particle size of the crushed raw materials should be controlled at 20-40 メッシュ, which is conducive to the uniform mixing of raw materials and the breaking of pigment agglomerates during extrusion.
Impurity Removal: The raw materials may contain impurities (such as metal particles, stones, ほこり) during production and transportation. Impurities not only affect the quality of the masterbatch, but also wear the screw and barrel of the extruder, and even cause equipment blockage. したがって, the raw materials must be filtered and removed before use, using a filter screen with appropriate mesh size to remove impurities.

2.2.2 Premixing

Premixing is the key step to improve the mixing and dispersing effect of masterbatch. According to the formula ratio, the dried, crushed and impurity-removed pigments, carriers and additives are put into a high-speed mixer for premixing. The purpose of premixing is to make the pigments and additives uniformly adhere to the surface of the carrier particles, form a preliminary mixture, and lay a foundation for the uniform dispersion during extrusion.

The key parameters of premixing are mixing speed, mixing time and mixing temperature. The mixing speed is generally 800-1200 回転数, the mixing time is 5-10 分, and the mixing temperature is controlled at 40-60℃. The appropriate mixing temperature can improve the adhesion of additives (such as dispersants) to the carrier and pigments, promoting uniform mixing. For masterbatch with high pigment content (のような 50% その上), the premixing time can be appropriately extended, and a small amount of dispersant can be added first to improve the dispersibility of pigments. After premixing, the mixture should be uniform in color, without obvious pigment agglomerates and additive particles.

2.2.3 Feeding and Conveying

The premixed mixture is sent to the feeding hopper of the twin-screw extruder through a screw feeder or a belt feeder. The feeding device of the extruder is usually equipped with a frequency conversion speed regulation function, which can adjust the feeding speed according to the screw speed and extrusion speed to ensure that the materials enter the extrusion cavity stably and uniformly, avoiding material accumulation or insufficient feeding.

The feeding hopper is also equipped with a drying device (such as an electric heating jacket) to prevent the raw materials from absorbing moisture again during feeding. For masterbatch with high pigment content and poor fluidity, a forced feeding device can be selected to ensure the smooth feeding of materials. 加えて, the feeding port of the extruder should be smooth, without dead corners, to avoid material sticking and accumulation.

2.2.4 溶融, Mixing and Shearing

The materials entering the extrusion cavity of the twin-screw extruder are pushed forward continuously by the rotating screws. The extrusion cavity is composed of a screw and a barrel, and the volume of the extrusion cavity gradually decreases along the axis direction. When the screws rotate, the materials are gradually compressed under the action of the screws and the barrel, and the pressure in the extrusion cavity gradually increases (generally 5-12MPa).

同時に, the materials are subjected to strong shear force and friction force generated by the relative movement between the screws and the barrel, スクリューフライト間と同様に. The shear force and friction force can fully break the agglomerates of pigments, make the pigments uniformly dispersed in the melted carrier, and promote the fusion and compatibility between the pigment, carrier and additives. The friction force can also generate a certain amount of heat, which is combined with the external heating of the barrel (electric heating or steam heating) to make the carrier gradually melt and plasticize.

The barrel of the extruder is usually divided into 4-6 temperature control sections (feeding section, melting section, mixing section, homogenizing section, die head section), and the temperature of each section is precisely controlled according to the type of masterbatch (キャリアタイプ, pigment type). 例えば, when processing PE masterbatch, the temperature of the feeding section is 100-120℃, the melting section is 160-180℃, the mixing section is 170-190℃, the homogenizing section is 160-180℃, and the die head section is 150-170℃. The precise temperature control can ensure that the carrier is fully melted without thermal decomposition, and the pigments are not decomposed or discolored.

The screw of the twin-screw extruder adopts a modular design, which can freely combine different screw elements (such as conveying elements, 要素を混合する, shearing elements) according to the type of masterbatch. 例えば, when processing masterbatch with high pigment content and easy agglomeration, more mixing elements and shearing elements can be configured to enhance the mixing and dispersing effect; when processing masterbatch with good fluidity, more conveying elements can be configured to improve production efficiency.

2.2.5 Extrusion and Shaping

The fully melted, mixed and dispersed material is pushed to the die head of the extruder by the screws. The die head of the masterbatch extruder is usually equipped with multiple circular die holes (the number and size of die holes are determined according to the particle size of the masterbatch). The material is extruded from the die head at a high speed to form continuous strip-shaped semi-finished products (the diameter of the strip is usually 2-5mm, which can be adjusted according to customer needs).

The temperature of the die head is slightly lower than that of the homogenizing section, which can prevent the material from decomposing due to excessive temperature and ensure the shaping effect of the strip. The extrusion speed is controlled according to the type of masterbatch and the particle size requirement, generally ranging from 1-3m/min. The extrusion pressure should be kept stable (fluctuation within ±0.5MPa), which can ensure the uniform diameter of the strip and the consistency of the masterbatch quality.

2.2.6 Cooling and Solidification

The extruded strip-shaped semi-finished products are sent to a cooling device for rapid cooling and solidification. The cooling method for masterbatch is usually water tank cooling, and the cooling water temperature is controlled at 20-30℃. The length of the cooling water tank is 3-5 meters, and the cooling time is 2-4 分. Rapid cooling can make the strip solidify quickly, maintain the shape and size of the strip, and avoid deformation and adhesion.

It should be noted that the cooling speed should be uniform. If the cooling speed is too fast, the internal stress of the strip will be too large, and the strip will be brittle and easy to break during granulation; if the cooling speed is too slow, the strip will be soft and easy to adhere, affecting the granulation effect. 冷却後, the surface of the strip should be dry, smooth and free of bubbles and cracks.

2.2.7 Cutting and Granulation

After cooling and solidification, the strip is sent to a granulator for cutting to form granular masterbatch products. The granulator is equipped with a rotary knife and a fixed knife, and the cutting speed is adjustable (generally 500-1000 回転数). The particle size of the masterbatch is controlled by adjusting the cutting speed and the speed of the strip conveying. The common particle size of masterbatch is 2-5mm (length and diameter are basically the same), which is convenient for mixing with plastic raw materials during later use.

The granulator should be equipped with a screening device to remove unqualified particles (such as too large, too small, agglomerated or broken particles). The qualified particles enter the next process, and the unqualified particles are crushed and recycled (after drying and premixing, they are re-extruded and granulated).

2.2.8 スクリーニング, Inspection and Packaging

The granulated masterbatch is sent to a vibrating screen for screening to further remove unqualified particles and impurities. The vibrating screen is equipped with a multi-layer screen (different mesh sizes), which can screen out masterbatch particles of different specifications according to customer needs.

After screening, the masterbatch needs to undergo quality inspection. The inspection items mainly include: 色 (uniformity, consistency with the standard sample), 分散性 (observed by microscope or test piece coloring), 集中 (tinting strength test), 水分含有量, particle size distribution, 等. Only the masterbatch that meets the quality standards can be packaged.

The packaging of masterbatch adopts sealed and moisture-proof packaging (such as plastic woven bags with inner plastic film, aluminum foil bags), and the packaging weight is usually 25kg/bag or 50kg/bag. The packaging bag is marked with the product name, モデル, 色, 集中, キャリアタイプ, 製造日, shelf life, manufacturer and other information. The packaged masterbatch should be stored in a dry, cool and ventilated warehouse, avoiding direct sunlight and moisture, and the shelf life is generally 6-12 月.

2.3 Key Factors Affecting Masterbatch Twin-Screw Extrusion Effect

The effect of twin-screw extrusion directly affects the quality of masterbatch (分散性, tinting strength, 安定性). There are many factors affecting the extrusion effect, mainly including raw material characteristics, formula ratio, premixing effect, extrusion parameters and equipment performance. Mastering these key factors and making scientific adjustments can ensure the stability of the extrusion effect and the consistency of product quality.

2.3.1 Raw Material Characteristics

The type, particle size, moisture content and purity of raw materials have a great impact on the extrusion effect. For pigments, the particle size should be uniform and fine (20-40 メッシュ), and the agglomeration degree should be low; organic pigments have poor heat resistance, so the extrusion temperature should be strictly controlled; inorganic pigments have high hardness, so the extruder should have good wear resistance. For carriers, the melting point and processing temperature should be consistent with the target plastic raw materials, and the compatibility with pigments should be good. For additives, the type and dosage should be reasonable, and the compatibility with carriers and pigments should be good.

加えて, the moisture content of raw materials must be strictly controlled below 0.1%; if the moisture content is too high, it will cause bubbles and agglomeration in the masterbatch. The purity of raw materials is also very important; impurities in raw materials will not only affect the product quality, but also wear the screw and barrel of the extruder.

2.3.2 Formula Ratio

The formula ratio of masterbatch (the ratio of pigment, carrier and additive) is the key to determining the quality of the product. The pigment content should be determined according to the coloring requirements and the type of pigment: high-concentration masterbatch (pigment content 50%-80%) can reduce the addition amount and production cost, but requires better dispersibility; low-concentration masterbatch (pigment content 10%-30%) has better dispersibility, しかし添加量が多く製造コストが高い.

分散剤の投与量は一般的に次のとおりです。 1%-5% 色素の投与量の; 分散剤が少なすぎると顔料の分散性が低下します。, 分散剤が多すぎると、マスターバッチと着色製品の機械的特性に影響を与えます。. その他の添加物の配合量 (相溶化剤, heat stabilizers, 潤滑剤) 一般的には 0.5%-3%, マスターバッチの種類と処理要件に応じて調整する必要があります. 配合比率は厳密に管理する必要があります, 誤差は±1%以内である必要があります, バッチ間の製品品質の一貫性を確保するため.

2.3.3 プレミキシング効果

予混合は押出加工の基礎です. プレミックスの均一性は、押出成形中の顔料の混合および分散効果に直接影響します。. 予混合が不均一な場合, the pigments cannot be uniformly adhered to the surface of the carrier, resulting in local agglomeration of pigments, uneven mixing of materials during extrusion, and reduced product dispersibility.

To ensure the premixing effect, it is necessary to control the mixing speed (800-1200 回転数), 混合時間 (5-10 分) and mixing temperature (40-60℃). For masterbatch with high pigment content, the premixing time can be appropriately extended, and the dispersant can be added first and mixed with the pigment, then mixed with the carrier and other additives. 加えて, the premixed mixture should be inspected; if there are obvious pigment agglomerates, it should be crushed and remixed.

2.3.4 Extrusion Parameters

Extrusion parameters are the most important factors affecting the extrusion effect, mainly including screw speed, extrusion temperature and extrusion pressure.

スクリュー速度: The screw speed of twin-screw extruders for masterbatch processing generally ranges from 200 に 800 回転数. The higher the screw speed, the greater the shear force and friction force received by the materials, the better the mixing and dispersing effect of pigments, and the higher the production efficiency. しかし, if the screw speed is too high, the residence time of the materials in the extrusion cavity is too short, resulting in incomplete melting of the carrier, insufficient mixing of materials, and uneven dispersibility; if the screw speed is too low, the shear force and friction force are insufficient, the pigment agglomerates cannot be fully broken, and the production efficiency is low.
The screw speed should be adjusted according to the type of masterbatch: for masterbatch with high pigment content and easy agglomeration (such as black masterbatch, white masterbatch), a higher screw speed (500-800 回転数) is needed to ensure the uniform dispersion of pigments; for masterbatch with organic pigments (poor heat resistance), a moderate screw speed (300-500 回転数) is needed to avoid overheating and pigment decomposition.
Extrusion Temperature: The extrusion temperature is the key to ensuring the melting of the carrier and the stability of the pigment. The temperature of each section of the barrel and die head must be precisely controlled according to the type of masterbatch (キャリアタイプ, pigment type). The temperature of the feeding section is lower (slightly higher than the drying temperature of the raw materials), which is mainly to prevent the materials from caking and ensure smooth feeding; the temperature of the melting section is medium, which is mainly to promote the melting and plasticization of the carrier; the temperature of the mixing section is higher, which is mainly to enhance the shear and mixing effect, and promote the uniform dispersion of pigments; the temperature of the homogenizing section is slightly lower than the mixing section, which is mainly to ensure the uniform temperature and viscosity of the materials, and avoid thermal decomposition; the temperature of the die head section is slightly lower than the homogenizing section, which is to ensure the shaping effect of the strip.
The temperature control precision should reach ±1℃. 例えば, when processing PP masterbatch with organic pigments, the temperature of each section is: feeding section 110-130℃, melting section 170-190℃, mixing section 180-200℃, homogenizing section 170-190℃, die head section 160-180℃. If the temperature is too high, 顔料は分解し、キャリアは劣化します。; 温度が低すぎる場合, キャリアが完全に溶けていない, 顔料を均一に分散できません.
押出圧力: マスターバッチ二軸押出の押出圧力は通常、 5 ～12MPa. 押出キャビティ内の圧力は主にスクリューの圧縮率によって決まります。, ダイ穴サイズとスクリュー速度. 押出圧力が高いほど, 材料の混合と分散効果が向上する, ストリップの密度が高くなるほど. しかし, 圧力が高すぎる場合, エネルギー消費と機器の磨耗が増加します, ダイヘッドがブロックしてしまうことさえあります; 圧力が低すぎる場合, 材料を完全に圧縮して混合することはできません, ストリップが緩んでいる, そして分散性が悪い.
The extrusion pressure should be adjusted according to the type of masterbatch and the die head size: for masterbatch with high pigment content and poor fluidity, a higher extrusion pressure is needed; for masterbatch with good fluidity, a moderate extrusion pressure is sufficient. The extrusion pressure should be kept stable, and the fluctuation should be within ±0.5MPa, to ensure the uniform diameter of the strip and the consistency of the masterbatch quality.

2.3.5 Equipment Performance

The performance of the twin-screw extruder directly determines the extrusion effect. The key performance indicators of the extruder include mixing and dispersing capacity, 温度制御精度, 耐摩耗性, conveying capacity and intelligent control capacity. Zhuoyue の押出機全シリーズ (HTSベーシック/プラス/スーパー, ZTE, HTE) マスターバッチ処理用に特別に設計されています, with excellent performance in these aspects, which can effectively meet the processing needs of different types of masterbatch.

3. Zhuoyue’s Full Series Extruders: Professional Solutions for Masterbatch Processing

3.1.1 Excellent Mixing and Dispersing Effect

The core requirement of masterbatch processing is the uniform dispersion of pigments. All Zhuoyue’s twin-screw extruders adopt an intermeshing co-rotating structure, with a reasonable screw pitch, lead and compression ratio design. The intermeshing and rotating of the twin screws can generate strong shear force and kneading force, which can fully break the agglomerates of pigments (even small agglomerates of 100μm above), and make the pigments uniformly dispersed in the carrier. The mixing uniformity of the extruders can reach more than 95%, which is much higher than that of ordinary twin-screw extruders (85%-90%).

加えて, the screws of all series of extruders adopt a modular design, which can freely combine different types of screw elements (搬送要素, 要素を混合する, shearing elements) according to the type of masterbatch (such as color masterbatch, white masterbatch, black masterbatch) and pigment characteristics. 例えば, when processing black masterbatch with carbon black (easy agglomeration), more mixing elements and shearing elements can be configured to enhance the mixing and dispersing effect; when processing color masterbatch with organic pigments (poor heat resistance), more conveying elements and fewer shearing elements can be configured to shorten the residence time and avoid pigment decomposition.

3.1.2 Precise Temperature Control, Avoiding Pigment Decomposition

Masterbatch processing has strict requirements on temperature control, and the temperature fluctuation must be controlled within ±1℃ to avoid pigment decomposition and carrier degradation. All Zhuoyue’s extruders adopt an advanced intelligent temperature control system, which is composed of high-precision temperature sensors, heating elements and cooling elements. The barrel is divided into 4-6 independent temperature control sections, and the temperature of each section can be precisely adjusted and controlled in real time.

The temperature control system is equipped with a real-time monitoring and alarm function: if the temperature of any section exceeds the set range, システムは時間内にアラームプロンプトを発行します, and automatically adjust the heating power or start the cooling system to return the temperature to the set range. 加えて, the barrel of the extruder adopts a double-layer jacket design, which can realize rapid heating and cooling, and improve the response speed of temperature control. The die head is also equipped with an independent temperature control device, which ensures the uniform temperature of the die head and the stable shaping of the strip.

(4) Maintain equipment: Replace worn screw mixing elements, バレルとスクリュー; clean the die head regularly to avoid blockage; check the equipment regularly to ensure that the screw and barrel are properly matched.

5.2 Common Problem 2: Pigment Decomposition and Discoloration of Masterbatch

This problem is mainly manifested in the discoloration of the masterbatch (such as yellowing, darkening), the color is inconsistent with the standard sample, and even peculiar smell is generated. It is mostly caused by overheating of the material during extrusion processing, which is common in organic pigment masterbatch and engineering plastic masterbatch. The main causes and solutions are as follows:

5.2.1 Main Causes:

(1) Extrusion temperature is too high: The temperature of the mixing section, homogenizing section or die head is too high, exceeding the heat resistance limit of the pigment or carrier.
(2) The residence time of the material is too long: The screw speed is too low, the compression ratio is too large, resulting in the material staying in the extrusion cavity for too long (より多い 3 分), and thermal decomposition occurs.
(3) Poor heat dissipation of the equipment: The cooling system of the barrel fails, resulting in local overheating of the barrel.
(4) Raw material problems: The heat resistance of the pigment is poor, or the carrier is easy to degrade at high temperature.

5.2.2 ソリューション:

(1) Adjust extrusion temperature: Reduce the temperature of the mixing section, homogenizing section and die head appropriately, and control it within the heat resistance range of the pigment and carrier (150-220℃ for ordinary masterbatch, 200-280℃ for engineering plastic masterbatch); check the temperature sensor regularly to ensure accurate temperature control.
(2) Shorten the residence time: Increase the screw speed appropriately, reduce the compression ratio of the screw, and ensure that the residence time of the material in the extrusion cavity is 1-3 分.

(2) Extrusion parameter problems: The screw speed is too high, the shear force is too large, and the friction between the material and the screw/barrel is increased; the extrusion pressure is too high, which increases the wear of the screw and barrel.
(3) Equipment problems: The screw and barrel are made of materials with poor wear resistance, or the processing technology is improper; the screw and barrel are not properly matched, resulting in uneven stress and increased wear.

5.3.2 ソリューション:

(1) Optimize raw materials: Select pigments or fillers with small particle size (20-40 メッシュ) and low hardness; crush and sieve the raw materials to remove large particles; add appropriate lubricants (0.5%-2%) to reduce the friction between the material and the screw/barrel.
(2) Adjust extrusion parameters: Reduce the screw speed and extrusion pressure appropriately, and control the shear force within a reasonable range; avoid long-term high-speed and high-pressure operation of the equipment.
(3) Select high-wear-resistant equipment: Select extruders with high-wear-resistant screws and barrels, such as Zhuoyue’s HTS PLUS, HTS SUPER and HTE series, whose screws and barrels are made of imported wear-resistant alloy steel and undergo bimetallic composite or laser cladding treatment, which can greatly improve the service life; regularly check the wear of the screw and barrel, and replace them in time when the wear is serious.

5.4 Common Problem 4: Instability of Product Quality Between Batches, Color Difference

This problem is mainly manifested in the inconsistency of masterbatch quality (such as concentration, 分散性, 色) between different batches, resulting in color difference of downstream products, which affects the reputation of the manufacturer. The main causes and solutions are as follows:

5.4.1 Main Causes:

(1) Formula problem: The formula ratio is not strictly controlled, and the dosage of pigment, dispersant and other additives fluctuates (error exceeds ±1%).
(2) Raw material problem: The performance of raw materials (such as pigment tinting strength, carrier melting point) of different batches is inconsistent.
(3) Processing parameter problem: The extrusion temperature, スクリュー速度, feeding speed and other parameters fluctuate between different batches, resulting in inconsistent processing effect.
(4) Equipment problem: The equipment has poor stability, and the parameters (such as temperature, プレッシャー) cannot be kept stable for a long time.

5.4.2 ソリューション:

(1) Strictly control the formula ratio: Use high-precision weighing equipment to weigh raw materials, and the error is controlled within ±1%; establish a formula management system, and record the dosage of each raw material in detail.
(2) Standardize raw material procurement and inspection: Select raw material suppliers with stable quality, and inspect the performance of raw materials (such as tinting strength, particle size, 水分含有量) before use; for raw materials of different batches, conduct trial production first to ensure consistent performance.
