Polyvinyl Chloride (PVC) is one of the most widely used synthetic polymers in the world, valued for its excellent versatility, cost-effectiveness, makemikari kuramba, and mechanical properties. It has penetrated almost every field of modern life, from construction and packaging to automotive, electrical and electronic industries. Zvisinei, 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, mafuta ekuzora, and modifiers) through professional equipment, inoteverwa negranulation kana kuumba zvakananga, kuti uwane PVC makomisheni ane zvakagadzirirwa zvivakwa zvinosangana nezvinodiwa zvekushandisa.

1. Mhedziso yePVC Compound Mixing Technology
1.1 Basic Nheyo dzePVC Musanganiswa Musanganiswa
PVC musanganiswa wemusanganiswa inzira yakaoma yemuviri uye yemakemikari inosanganisa kusanganisa kwakasimba, kunyunguduka, plasticizing, kuveura, uye homogenization. Chinangwa chikuru ndechekuparadzira zvakasiyana-siyana zvinowedzera muPVC resin matrix, kubvisa kukanganisa kwemukati (zvakadai semhepo inoputika, agglomeration, uye kusaenzana kwechikamu kugovera) yemusanganiswa, uye kuvandudza dhigirii repurasitiki uye kugadzirisa mashandiro emukomboni, kuitira kuisa hwaro hwakasimba hwekugadzirisa kunotevera kwekuumbwa (zvakadai se extrusion, jekiseni kuumba, Calendering) uye yekupedzisira chigadzirwa kuita.
The mixing process of PVC compounds is usually divided into two stages: dry mixing and melt mixing. Dry mixing is the initial stage, which mainly involves mixing PVC resin powder with various additives (such as stabilizers, mafuta ekuzora, fillers, plasticizers for flexible PVC) in a high-speed mixer. The purpose of dry mixing is to make the additives uniformly adhere to the surface of PVC resin particles through the action of mechanical stirring and friction heat, and to preheat the mixture to a certain temperature, which is conducive to the subsequent melt plasticization. Melt mixing is the key stage, which is usually completed in extruders or internal mixers. Under the combined action of external heating and shear force generated by the screw (or rotor), the PVC resin particles are gradually melted and plasticized, and the additives are further dispersed into the resin matrix at the molecular level to form a uniform and stable melt system. Pakupedzisira, 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 Stabilizers:
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. 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, hardness, 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:
Ma modifiers anowedzerwa kuti avandudze chaiwo zvivakwa zvePVC makomisheni, sekukanganisa kupikisa, kupisa kuramba, uye pachena. Magadzirirwo akajairika anosanganisira acrylonitrile-butadiene-styrene (ABS) resin, methyl methacrylate-butadiene-styrene (MBS) resin, chlorinated polyethylene (CPE), uye acrylic resin.

The performance of modified PVC granules is relatively stable, which can avoid the fluctuation of product performance caused by uneven mixing of additives in direct molding, thus ensuring the consistency of product quality and reducing the product defect rate.
Fourth, it expands the application scope of PVC. Through targeted modification (such as adding different modifiers, plasticizers, and fillers), PVC compounds with different properties can be prepared, which can meet the requirements of different application fields. Semuyenzaniso, 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; PVC granules inodzoreredza moto inogona kushandiswa mukugadzira zvigadzirwa zvemagetsi nemagetsi.
