Polyvinyl Chloride (PVC) is one of the most widely used synthetic polymers in the world, valued for its excellent versatility, cost-effectiveness, pale kemika, and mechanical properties. It has penetrated almost every field of modern life, from construction and packaging to automotive, electrical and electronic industries. Eia naʻe, 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, mea hoʻopaʻa, nā mea hoʻopiha, lubricants, a me nā mea hoʻololi) ma o na lako oihana, ukali ʻia e ka granulation a i ʻole ka hoʻoheheʻe pololei ʻana, e kiʻi i nā pūhui PVC me nā waiwai i hoʻokō ʻia i nā koi noi kikoʻī.

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, hehee ana, plasticizing, shearing, 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, hoʻoheheʻe ʻia, calendering) and the final product performance.
Hoʻokaʻawale pinepine ʻia ke kaʻina hui ʻana o nā pūhui PVC i ʻelua mau pae: hui maloʻo a hui hoʻoheheʻe. ʻO ka hui ʻana maloʻo ka pae mua, ka mea nui e hoʻohui i ka pauka resin PVC me nā mea hoʻohui like ʻole (e like me nā stabilizers, lubricants, nā mea hoʻopiha, plasticizers no ka PVC hikiwawe) i loko o kahi huila kiʻekiʻe. ʻO ke kumu o ka hui ʻana maloʻo, ʻo ia ka hoʻopili ʻana i nā mea hoʻohui i ka ʻili o nā ʻāpana resin PVC ma o ka hana o ka hoʻoulu ʻana a me ka wela friction., a e hoʻomaʻamaʻa mua i ka hui ʻana i kahi mahana, mea kūpono i ka plasticization hehee hope. ʻO ka hui ʻana i hoʻoheheʻe ʻia ke kahua nui, ka mea maʻamau i hoʻopau ʻia i nā extruders a i ʻole nā mea hoʻohui i loko. Ma lalo o ka hana hui ʻana o ka hoʻomehana waho a me ka ikaika shear i hana ʻia e ka wili (a i ʻole rotor), hoʻoheheʻe ʻia nā ʻāpana resin PVC a hoʻoheheʻe ʻia, a hoʻopuehu hou ʻia nā mea hoʻohui i loko o ka resin matrix i ka pae mole e hana i kahi ʻōnaehana hoʻoheheʻe paʻa a paʻa.. ʻO ka hope loa, hoʻoheheʻe ʻia ka heheʻe, granulated a i hana pololei ʻia i huahana.
1.2 Nā mea hoʻohui kiʻi no ka hui pū ʻana o PVC
Hoʻoholo nui ʻia ka hana o nā pūhui PVC e ke ʻano, ka hopena a me ka hui ʻana o nā mea hoʻohui. Hoʻokani nā mea hoʻohui like ʻole i nā hana like ʻole i ka hui ʻana a me ke kaʻina hana a me nā huahana hope. Eia nā mea hoʻohui kī maʻamau i hoʻohana ʻia i ka hui pū ʻana o PVC:
1.2.1 Nā mea hoʻokūpaʻa:
Hiki ke hoʻohaʻahaʻa ʻia ka PVC resin i nā wela kiʻekiʻe (ma luna o 100 ℃), e alakaʻi ai i ka ʻeleʻele (mai keokeo a melemele, palaunu, ʻeleʻele hoʻi), ka ho'ēmiʻana i nā waiwai mechanical a me ka lilo o ka waiwai hoʻohana. No laila, 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. Among them, 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. Among them, 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, paakiki, 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 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. Common lubricants include stearic acid, calcium stearate, zinc stearate, and paraffin. According to the action mechanism, lubricants can be divided into internal lubricants and external lubricants. Hiki i nā lubricants i loko ke hoʻemi i ka friction ma waena o nā kaulahao molekala PVC, hoʻomaikaʻi i ka hana plasticization; hiki i nā lubricants waho ke hana i kahi kiʻi lubricating ma ka ʻili o ka mea, e ho'ēmi i ka hakakā ma waena o nā mea a me nā mea hana.
1.2.5 Nā mea hoʻololi:
Hoʻohui ʻia nā mea hoʻololi e hoʻomaikaʻi i nā waiwai kikoʻī o nā pūhui PVC, e like me ke kū'ē i ka hopena, pale wela, a me ka maopopo. ʻO nā mea hoʻololi maʻamau ka acrylonitrile-butadiene-styrene (ABS) resin, methyl methacrylate-butadiene-styrene (MBS) resin, polyethylene chlorinated (CPE), a me ka resin acrylic. ʻo kahi laʻana, Hiki i ka MBS resin ke hoʻomaikaʻi maikaʻi i ka hopena o ka hopena o nā pūhui PVC paʻa, hana ia lakou i kupono no ka hana ana i na paipu plastik, profiles, a me nā ʻāpana hoʻoheheʻe injection e koi ai i ka paʻakikī kiʻekiʻe.
1.3 Koʻikoʻi o ka hoʻololi ʻana a me ka Granulation PVC Compound
I ka nui o nā hiʻohiʻona hana PVC, PVC resin needs to be modified and granulated first before subsequent molding processing. This is because modified granulation can bring many obvious advantages:
Ka mua, 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, which avoids the problems of insufficient plasticization, uneven component distribution, and internal defects in direct molding of pure resin, thus improving the processing performance of the material.
Ka lua, it simplifies the subsequent processing process. The PVC granules after modification and granulation have uniform particle size, good fluidity, and stable performance. They can be directly used in extrusion, hoʻoheheʻe ʻia, calendering, puhi puhi a me nā kaʻina hana hoʻoheheʻe ʻē aʻe me ka ʻole o ka hui ʻana a i ʻole ka hoʻoponopono mua ʻana, e hoemi ana i ka hana hana, hoʻomaikaʻi i ka pono hana, a hoʻemi i ka ikaika o ka hana o nā mea hana.
Ke kolu, hōʻoia i ka paʻa o ka maikaʻi o ka huahana. ʻO ka hana o nā granules PVC i hoʻololi ʻia he kūpaʻa, hiki iā ia ke pale i ka loli o ka hana huahana ma muli o ka hui ʻole ʻana o nā mea hoʻohui i ka hoʻoheheʻe pololei ʻana, no laila e hōʻoiaʻiʻo ana i ka kūlike o ka maikaʻi o ka huahana a me ka hōʻemi ʻana i ka helu hemahema o ka huahana.
Ka ʻehā, hoʻonui ia i ka laulā noi o PVC. Ma o ka hoʻololi ʻia ʻana (e like me ka hoʻohui ʻana i nā mea hoʻololi like ʻole, plasticizers, a me na mea hoopiha), Hiki ke hoʻomākaukauʻia nā pūhui PVC me nāʻano likeʻole, hiki ke hoʻokō i nā koi o nā kahua noi like ʻole. ʻo kahi laʻana, Hiki ke hoʻohana ʻia nā granules PVC paʻa me ka rigidity kiʻekiʻe a me ka hopena i ka hana ʻana i nā paipu plastik a me nā profiles; hiki ke hoʻohana ʻia nā granules PVC maʻalahi me ka maʻalahi a me ka palupalu i ka hana ʻana i nā hoses, uwea, a me nā kiʻi paʻi kiʻi; Hiki ke hoʻohana ʻia nā granules PVC pale ahi i ka hana ʻana i nā huahana uila a me nā uila.
Pono e hoʻoikaikaʻia no nā huahana PVC me nā koi kūikawā (e like me ke kūpaʻa wela kiʻekiʻe, pale ʻino, hoʻopaʻa ahi, a me ka maopopo) a me nā palapala hoʻololi PVC, hoʻokō mau mākou i ka hoʻomohala maʻamau e like me nā pono kikoʻī o nā mea kūʻai aku. Na kā mākou hui ʻenehana e kamaʻilio hohonu me nā mea kūʻai aku e hoʻomaopopo i kā lākou mau hiʻohiʻona hoʻohana huahana, pono hana, a me nā koina hana, and then design the most suitable modified formula and mixing process to ensure that the produced PVC compounds can fully meet the customer’s expectations.
2. Extrusion Equipment for PVC Compound Mixing and Granulation
Extruders are the core equipment for PVC compound mixing, granulation, and molding processing. They play a crucial role in the melt plasticization, shear mixing, and extrusion molding of PVC mixtures. The working principle of extruders is to use external power transmission to drive the screw to rotate, and use the heat transfer of external heating elements and the shear heat generated by the rotation of the screw to realize the solid conveying, compaction, hehee ana, shear mixing, and extrusion of PVC materials. As an important equipment in plastic molding processing, extruders are widely used in the granulation of PVC compounds and the molding of various PVC products, and occupy an irreplaceable position in the PVC processing industry.
According to the structure and performance of extruders, we have developed two series of extruders suitable for PVC compound mixing and granulation, namely the ZTE MODEL series and the HTE series. These two series of extruders have their own characteristics and advantages, and can meet the different needs of customers for production capacity, maikaʻi huahana, and cost control.
2.1 ZTE MODEL Extruder: Cost-Effective Choice for General PVC Materials
The ZTE MODEL extruder is a cost-effective extrusion equipment independently developed by us, which is mainly designed for the mixing, granulation, and extrusion molding of general PVC materials. Hoʻolālā ʻia nā ʻāpana o kēia moʻo extruders, hiki ke hoʻololi maikaʻi ʻia i ka hapa nui o nā mea PVC (me ka PVC paʻa maʻamau, PVC hikiwawe, a me ka PVC hoʻololi maʻamau), a loaʻa iā ia nā pōmaikaʻi o ka hana maʻalahi, hana paʻa, uku mālama haʻahaʻa, a me ka hana uku nui.
Ma keʻano o ka hoʻolālā hoʻolālā, ʻO ka ZTE MODEL extruder e hoʻohana i kahi hoʻolālā hoʻokahi-screw, nona ke ano maalahi, hana hilinaʻi, a me ka mālama maʻalahi. Hana ʻia ka wili me ke kila kila kila kiʻekiʻe,经过 ka mīkini pololei a me ka mālama wela, he oolea kiekie, ʻaʻahu kūʻē, a me ka pale ʻana i ka corrosion, a hiki ke hooloihi pono i ke ola lawelawe o ka wili. Hana ʻia ka barela me ke kila kila kiʻekiʻe, me kahi mea hoʻomehana i kūkulu ʻia a me kahi ʻōnaehana hoʻomaha, ka mea hiki ke hoomalu pono i ka wela o ka barela, ensuring that the PVC mixture is fully melted and plasticized, and avoiding thermal degradation of the material due to excessive temperature.
In terms of performance parameters, the ZTE MODEL extruder has a wide range of adjustable speed, which can adjust the screw speed according to the type of PVC material and the requirements of the granulation process, so as to control the production capacity and the degree of shear mixing. The extrusion pressure of the extruder is stable, which can ensure the uniform particle size of the extruded granules and good fluidity. The production capacity of the ZTE MODEL extruder ranges from 50kg/h to 200kg/h, which is suitable for small and medium-sized enterprises and customers with moderate production demand.
In addition, the ZTE MODEL extruder is equipped with a complete control system, which adopts a PLC control panel, with simple operation and clear display. Operators can easily set and adjust parameters such as temperature, ka māmā holo, a me ke kaomi extrusion, and can realize automatic control of the production process, reducing the influence of human factors on product quality. The ZTE MODEL extruder also has good compatibility, and can be matched with different auxiliary equipment (such as high-speed mixers, mea lawe hooluolu, nā pelletizers, and sieves) to form a complete PVC compound granulation production line, improving production efficiency.
The ZTE MODEL extruder is widely used in the production of general PVC granules, such as PVC pipe granules, PVC profile granules, PVC film granules, and PVC injection molding granules. He koho kūpono no nā mea kūʻai aku e ʻimi nei i ka hana paʻa a me ke kumukūʻai kūpono.
2.2 HTE Series Extruder: ʻO ka hopena kiʻekiʻe a me ka mālama ʻana i ka ikehu
ʻO ka HTE series extruder kahi mea hana extrusion kiʻekiʻe i hoʻomohala ʻia e mākou no ka hui pū ʻana o PVC kiʻekiʻe., granulation, a me ka hoʻoheheʻe extrusion. Hoʻohui kēia pūʻulu extruders i ka hana kiʻekiʻe a me ka hana kiʻekiʻe, hoʻohana i ka hoʻolālā hoʻolālā holomua a me ka ʻenehana kumu, a hiki ke hoʻomaikaʻi maikaʻi i ka hiki ke hana, hoemi i ka ikehu, a e hōʻoia i ka kiʻekiʻe o nā pūhui PVC. He kūpono loa ia no ka hui ʻana a me ka granulation o nā pūhui PVC i hoʻololi ʻia kiʻekiʻe (e like me ka PVC hopena kiʻekiʻe, PVC pale ahi, pvc alohilohi) a me nā huahana PVC me nā koi hana koʻikoʻi.
Ma keʻano o ka hoʻolālā hoʻolālā, ka HTE moʻo extruder apono i ka māhoe-screw hale, which has obvious advantages compared with the single-screw extruder in terms of shear mixing, plasticization efficiency, and production capacity. The twin-screw can generate strong shear force and mixing effect during rotation, which can make the PVC mixture and additives more uniformly mixed, and the plasticization degree is higher, thus improving the performance of the PVC compound. According to the shape of the screw, the twin-screw extruder can be divided into conical twin-screw extruder and parallel twin-screw extruder. Among them, the conical twin-screw extruder is an ideal choice for rigid PVC compound mixing and granulation.
The conical twin-screw extruder in the HTE series has a unique conical screw design, with a large screw diameter at the feeding end and a small screw diameter at the extrusion end. Hiki i kēia hoʻolālā ke hana i ka hui ʻana o PVC me ka compressed i ke kaʻina o ka lawe ʻana, a piʻi mālie ka ikaika ʻako, He mea kūpono ia i ka hoʻoheheʻe ʻana a me ka plasticization o ka resin PVC paʻa (nona ka viscosity kiʻekiʻe a koi i ka ikaika shear ikaika no ka plasticization). I ka manawa like, ʻO ka conical twin-screw extruder he hana hoʻomaʻemaʻe ponoʻī, hiki ke pale i ka hōʻiliʻili ʻana o nā mea i loko o ka wili a me ka barela, e hoemi i ka hoopau waiwai, a e hōʻoia i ka paʻa o ka hana hana.
Ma ke ano o ke koho mea, ʻO ka wili a me ka pahu o ka HTE series extruder i hana ʻia me ke kila kila kila maikaʻi loa.,Ma hope o ka mālama ʻana i ka ʻili kūikawā (e like me ka lapaʻau nitriding), ʻo ia ka mea e hoʻomaikaʻi hou ai i ka paʻakikī a me ka pale ʻana o ka wili a me ka barela, and can adapt to the mixing and granulation of PVC compounds containing fillers (such as calcium carbonate) and corrosive additives, prolonging the service life of the equipment.
In terms of performance advantages, the HTE series extruder has the characteristics of high production capacity, low energy consumption, and good product quality. Compared with the ZTE MODEL extruder, the HTE series extruder can increase the production capacity by 30%-50% under the same power condition, and the energy consumption per unit product can be reduced by 20%-30%, which can effectively reduce the production cost of customers and improve the market competitiveness of their products. I ka manawa like, the HTE series extruder has a more precise temperature control system and speed control system, which can accurately control the plasticization temperature, shear speed, a me ke kaomi extrusion o ka hui PVC, e hōʻoia i ka paʻa o ka hana o nā granules PVC i hana ʻia, a hoʻokō i nā koi koʻikoʻi o nā huahana kiʻekiʻe.
In addition, ua lako ka HTE series extruder me kahi ʻōnaehana naʻauao holomua, ʻo ia ka mea e hoʻohana i kahi papa mana hoʻopā a hiki ke ʻike i ka nānā ʻana i ka manawa maoli a me ka hoʻoponopono ʻana i ke kaʻina hana. Loaʻa i ka ʻōnaehana hoʻomalu nā hana e like me ka alarm fault, hoʻomanaʻo ʻāpana, a pani 'akomi, hiki ke hoʻomaikaʻi maikaʻi i ka palekana a me ka hilinaʻi o ke kaʻina hana, e ho'ēmi i ka ikaika o ka hana o nā mea hana, a hoʻomaikaʻi i ka hana hana. Hiki ke hoʻohālikelike ʻia ka HTE series extruder me nā mea kōkua kiʻekiʻe (e like me precision kiʻekiʻe-wikiwiki mixers, nā pelletizer hoʻoluʻu ea, a me nā mīkini hoʻopiha piha) to form an automatic PVC compound granulation production line, realizing the integration of feeding, huikau, plasticizing, extruding, granulating, cooling, a me ka paʻi ʻana, further improving production efficiency and product quality.
The HTE series extruder is widely used in the production of high-grade PVC compounds, such as high-impact PVC pipe granules, flame-retardant PVC cable granules, transparent PVC packaging granules, and medical PVC granules. It is a high-performance and energy-saving solution for customers who pursue high product quality, high production efficiency, and low energy consumption.
