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, rewa, 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, whakarewa werohanga, calendering) and the final product performance.
The mixing process of PVC compounds is usually divided into two stages: te whakaranu maroke me te whakaranu rewa. Ko te whakaranu maroke te waahi tuatahi, Ko te nuinga ko te whakaranu i te paura kapia PVC me nga momo taapiri (pērā i ngā pūmau, whakahinuhinu, whakakī, plasticizers mo PVC ngawari) i roto i te whakaranu tere tere. Ko te kaupapa o te whakaranu maroke ko te whakakotahi i nga taapiri ki te mata o nga matūriki kapia PVC na roto i te mahi o te whakaoho miihini me te wera waku., me te whakamahana i te ranunga ki tetahi pāmahana, e pai ana ki te whakakikoruatanga rewa o muri mai. Ko te whakaranu rewa te waahi matua, which is usually completed in extruders or internal mixers. I raro i te mahi whakakotahi o te whakawera o waho me te kaha kutikuti i hangaia e te huri (rotor ranei), ko nga matūriki kapia PVC ka rewa, ka whakakikoruatia, and the additives are further dispersed into the resin matrix at the molecular level to form a uniform and stable melt system. Ka mutu, 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 Pūmau:
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. Ko nga whakapumau PVC noa kei roto ko nga whakapumau i runga i te mata, konupūmā-konutea whakapūmau hiato, barium-cadmium stabilizers, me te whakapumau tine pararopi. I roto ia ratou, Ko te konupūmā-konutea whakapūmau hiato e whakamahia whānuitia ana na te pai o te taiao, kore-paitini, me te pai o te waiariki, e rite ana ki nga whakaritenga tiaki taiao o te ao mo nga hua kirihou.
1.2.2 Kaiwhakapaipai:
Ka whakamahia te nuinga o nga Plasticizers i roto i nga puhui PVC ngawari ki te whakaiti i te pāmahana whakawhiti karaihe o te PVC resin, whakapai ake i tona ngawari, te pakari me te kaha ki te tukatuka. Ka taea e ratou te kuhu ki roto i te mekameka ngota o te PVC, whakangoikore i te kaha o waenga ngota, kia ngawari te neke i te mekameka ngota, na reira ka ngawari te puhui PVC me te ngawari ki te tukatuka. Kei roto i nga mea whakahiato noa te dioctyl phthalate (DOP), dioctyl terephthalate (DOTP), diisononyl phthalate (DINP), me te hinu epoxy soybean. I roto ia ratou, 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 Nga whakakī:
Fillers are added to PVC compounds to reduce production costs, improve the rigidity, pakeke, 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. 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, ātete wera, and transparency. Common modifiers include acrylonitrile-butadiene-styrene (ABS) resin, methyl methacrylate-butadiene-styrene (MBS) resin, chlorinated polyethylene (CPE), and acrylic resin. Hei tauira, MBS resin can significantly improve the impact resistance of rigid PVC compounds, making them suitable for the production of plastic pipes, pūkete, 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:
Tuatahi, 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.
Tuarua, 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, whakarewa werohanga, calendering, blow molding and other molding processes without additional mixing or preprocessing, which reduces the production process, improves production efficiency, and reduces the labor intensity of operators.
Third, it ensures the stability of product quality. The performance of modified PVC granules is relatively stable, ka taea te karo i te rerekee o nga mahi hua na te whakaranu koretake o nga taapiri i roto i te hanga tika, na te whakarite i te riterite o te kounga o te hua me te whakaheke i te reeti hapa o te hua.
Tuawha, ka whakawhānuihia te waahanga tono o PVC. Na roto i nga whakarereketanga kua whakaritea (penei me te taapiri i nga momo whakarereke, nga kaiwhakaahua, me nga whakakii), Ka taea te whakarite i nga puhui PVC me nga ahuatanga rereke, ka taea te whakatutuki i nga whakaritenga o nga waahanga tono rereke. Hei tauira, Ka taea te whakamahi i nga papura PVC pakari me te kaha o te rigidity me te atete paanga ki te hanga paipa kirihou me nga korero; Ka taea te whakamahi i nga granules PVC ngawari me te ngawari me te ngawari ki te hanga i nga ngongo, taura, me nga kiriata kapi; Ka taea te whakamahi i nga granules PVC mura-muri ki te hanga i nga hua hiko me te hiko.
Me whakanuihia mo nga hua PVC me nga whakaritenga motuhake (pērā i te ātete ki te pāmahana teitei, parenga waikura, te mura o te mura, and transparency) me nga tauira PVC kua whakarereketia, mahi tonu matou i te whanaketanga whakaritenga rite ki nga hiahia motuhake o kiritaki. Ka whakahaerehia e ta maatau roopu hangarau nga korero hohonu me nga kaihoko kia mohio ai ki o raatau ahuatanga whakamahinga hua, whakaritenga mahi, me nga utu whakaputa, katahi ka hoahoa i te tauira whakarereke tino pai me te mahi whakaranu hei whakarite ka taea e nga puhui PVC kua puta te whakatutuki i nga tumanako a te kaihoko..
2. Taputapu Tangohanga mo te Whakaranu Puhui PVC me te Whakanui

It is especially suitable for the mixing and granulation of high-grade modified PVC compounds (such as high-impact PVC, flame-retardant PVC, transparent PVC) and PVC products with strict performance requirements.
In terms of structural design, the HTE series extruder adopts a twin-screw structure, which has obvious advantages compared with the single-screw extruder in terms of shear mixing, plasticization efficiency, me te kaha whakaputa. 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. I roto ia ratou, 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. This design can make the PVC mixture gradually compressed in the process of conveying, and the shear force gradually increases, which is conducive to the melting and plasticization of rigid PVC resin (which has high viscosity and requires strong shear force for plasticization). I taua wa ano, the conical twin-screw extruder has good self-cleaning performance, which can avoid the accumulation of material in the screw and barrel, reduce the waste of material, and ensure the stability of the production process.
In terms of material selection, the screw and barrel of the HTE series extruder are made of high-quality wear-resistant and corrosion-resistant alloy steel,经过 special surface treatment (such as nitriding treatment), which further improves the hardness and wear resistance of the screw and barrel, 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, iti kohi pūngao, 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 taua wa ano, the HTE series extruder has a more precise temperature control system and speed control system, which can accurately control the plasticization temperature, shear speed, and extrusion pressure of the PVC mixture, ensuring that the performance of the produced PVC granules is stable and uniform, and meeting the strict requirements of high-end products.
