Polyvinyl kiloraidi (PVC) is one of the most widely used synthetic polymers in the world, valued for its excellent versatility, cost-effectiveness, kemikali resistance, ati darí-ini. It has penetrated almost every field of modern life, from construction and packaging to automotive, electrical and electronic industries. Sibẹsibẹ, pure PVC resin has inherent limitations such as poor thermal stability, insufficient impact resistance, and narrow processing window, which restrict its application in high-performance scenarios. To overcome these shortcomings and expand its application scope, PVC compound mixing technology has emerged as a key link in the PVC processing industry. This technology involves mixing PVC resin with various additives (such as plasticizers, stabilizers, fillers, lubricants, and modifiers) through professional equipment, followed by granulation or direct molding, lati gba awọn agbo ogun PVC pẹlu awọn ohun-ini ti o ni ibamu ti o pade awọn ibeere ohun elo kan pato.

1. Overview of PVC Compound Mixing Technology
1.1 Basic Principles of PVC Compound Mixing
PVC compound mixing is a complex physical and chemical process that integrates solid mixing, yo, plasticizing, irẹrun, and homogenization. The core goal is to uniformly disperse various additives into the PVC resin matrix, eliminate internal defects (such as air bubbles, agglomeration, and uneven component distribution) of the mixture, and improve the plasticization degree and processing performance of the compound, so as to lay a solid foundation for the subsequent molding processing (such as extrusion, abẹrẹ igbáti, calendering) and the final product performance.
The mixing process of PVC compounds is usually divided into two stages: gbẹ dapọ ati yo dapọ. Idapọ gbigbẹ jẹ ipele ibẹrẹ, eyi ti o kun pẹlu dapọ PVC resini lulú pẹlu orisirisi awọn afikun (gẹgẹ bi awọn stabilizers, lubricants, fillers, plasticizers fun rọ PVC) ni a ga-iyara aladapo. Idi ti dapọ gbigbẹ ni lati jẹ ki awọn afikun ni iṣọkan faramọ oju ti awọn patikulu resini PVC nipasẹ iṣe ti aruwo ẹrọ ati ooru ija., ati lati ṣaju adalu si iwọn otutu kan, eyi ti o jẹ conducive si awọn tetele yo plasticization. Yo dapọ ni awọn bọtini ipele, eyi ti o ti wa ni maa pari ni extruders tabi ti abẹnu mixers. Labẹ iṣẹ apapọ ti alapapo ita ati agbara rirẹ ti ipilẹṣẹ nipasẹ dabaru (tabi ẹrọ iyipo), awọn patikulu resini PVC ti wa ni diėdiė yo ati ṣiṣu, and the additives are further dispersed into the resin matrix at the molecular level to form a uniform and stable melt system. Níkẹyìn, the melt is extruded, granulated or directly formed into products.
1.2 Key Additives for PVC Compound Mixing
The performance of PVC compounds is largely determined by the type, dosage and mixing effect of additives. Different additives play different roles in the mixing and processing process and the final products. The following are the key additives commonly used in PVC compound mixing:
1.2.1 Awọn imuduro:
PVC resin is prone to thermal degradation at high temperatures (above 100℃), which will lead to discoloration (from white to yellow, brown, even black), reduction of mechanical properties and loss of use value. Therefore, stabilizers must be added to PVC compounds to improve their thermal stability. Common PVC stabilizers include lead-based stabilizers, calcium-zinc composite stabilizers, barium-cadmium stabilizers, and organic tin stabilizers. Lára wọn, calcium-zinc composite stabilizers are widely used due to their environmental friendliness, non-toxicity, and good thermal stability, which are in line with the global environmental protection requirements for plastic products.
1.2.2 Plasticizers:
Plasticizers are mainly used in flexible PVC compounds to reduce the glass transition temperature of PVC resin, improve its flexibility, toughness and processability. They can penetrate into the molecular chain of PVC, weaken the intermolecular force, make the molecular chain easy to move, thus making the PVC compound soft and easy to process. Common plasticizers include dioctyl phthalate (DOP), dioctyl terephthalate (DOTP), diisononyl phthalate (DINP), and epoxy soybean oil. Lára wọn, DOTP has the advantages of environmental protection, low volatility, and good compatibility with PVC, and is widely used in high-grade flexible PVC products (such as medical hoses, food packaging films).
1.2.3 Fillers:
Fillers are added to PVC compounds to reduce production costs, improve the rigidity, lile, wear resistance and dimensional stability of products, and adjust the density of compounds. Common fillers include calcium carbonate (light calcium carbonate, heavy calcium carbonate), talcum powder, kaolin, and carbon black. Calcium carbonate is the most widely used filler due to its low price, abundant sources, and good compatibility with PVC. The addition of an appropriate amount of calcium carbonate can not only reduce costs but also improve the processing fluidity and impact resistance of PVC compounds.
1.2.4 Awọn lubricants:
Lubricants are used to reduce the friction between PVC resin particles, between the mixture and the equipment (such as the inner wall of the mixer, the screw of the extruder), and between the melt and the mold, so as to improve the processing fluidity of the compound, prevent the material from adhering to the equipment, and ensure the smooth progress of the mixing and molding process. Awọn lubricants ti o wọpọ pẹlu stearic acid, kalisiomu stearate, zinc stearate, and paraffin. According to the action mechanism, lubricants can be divided into internal lubricants and external lubricants. Internal lubricants can reduce the friction between PVC molecular chains, improve the plasticization efficiency; external lubricants can form a lubricating film on the surface of the material, reduce the friction between the material and the equipment.
1.2.5 Modifiers:
Modifiers are added to improve specific properties of PVC compounds, such as impact resistance, ooru resistance, and transparency. Common modifiers include acrylonitrile-butadiene-styrene (ABS) resin, methyl methacrylate-butadiene-styrene (MBS) resin, chlorinated polyethylene (CPE), and acrylic resin. Fun apere, MBS resin can significantly improve the impact resistance of rigid PVC compounds, making them suitable for the production of plastic pipes, awọn profaili, and injection molding parts that require high toughness.
1.3 Importance of PVC Compound Modification and Granulation
In most PVC processing scenarios, PVC resin needs to be modified and granulated first before subsequent molding processing. This is because modified granulation can bring many obvious advantages:
Ni akọkọ, it improves the plasticization degree of PVC. Through the combined action of dry mixing and melt mixing in the granulation process, PVC resin particles are fully melted and plasticized, and additives are uniformly dispersed, eyi ti o yago fun awọn isoro ti insufficient plasticization, uneven paati pinpin, ati awọn abawọn inu ni sisọ taara ti resini mimọ, nitorina imudarasi iṣẹ ṣiṣe ti ohun elo naa.

Wọn le ṣee lo taara ni extrusion, abẹrẹ igbáti, calendering, fe igbáti ati awọn miiran igbáti lakọkọ lai afikun dapọ tabi preprocessing, eyi ti o din isejade ilana, mu gbóògì ṣiṣe, ati ki o din ise kikankikan ti awọn oniṣẹ.

Ẹkẹrin, it expands the application scope of PVC. Through targeted modification (such as adding different modifiers, pilasitik, and fillers), PVC compounds with different properties can be prepared, which can meet the requirements of different application fields. Fun apere, rigid PVC granules with high rigidity and impact resistance can be used in the production of plastic pipes and profiles; flexible PVC granules with good flexibility and softness can be used in the production of hoses, cables, and packaging films; flame-retardant PVC granules can be used in the production of electrical and electronic products.
It should be emphasized that for PVC products with special requirements (such as high temperature resistance, corrosion resistance, flame retardancy, and transparency) ati PVC títúnṣe fomula, a nigbagbogbo ṣe idagbasoke ti adani ni ibamu si awọn iwulo pato ti awọn alabara.

2.3 Key Considerations in Selecting PVC Extruders
When selecting extruders for PVC compound mixing and granulation, customers need to comprehensively consider the following factors to ensure that the selected equipment can meet their actual production needs:
2.3.1 Type of PVC Material:
Different types of PVC materials (PVC kosemi, rọ PVC, modified PVC) have different processing characteristics, so it is necessary to select the appropriate extruder type. Fun apere, rigid PVC has high viscosity and requires strong shear force for plasticization, so a conical twin-screw extruder (HTE series) is preferred; flexible PVC has good fluidity and low viscosity, so a single-screw extruder (ZTE MODEL) or a parallel twin-screw extruder can be selected.
