(Summary description)Nylon, polyamide, polyoxymethylene, resin, polyester, acrylic, polyurethane, vulcanized rubber, elastomer, polyester rubber, polycarbonate, polysulfone, polyethylene, rubber, polyetheretherketone, polypropylene, polystyrene, Phenolic resin, polyvinyl chloride, silica fume... Up to now, there are more than 300 different types of plastics in the world. Why do they have so many types? Because the plastic we use is not a single substance, but is formulated from many raw materials. The production of plastics is inseparable from auxiliary materials and additives, such as carbon black, white carbon black, black carbon black, titanium dioxide, calcium carbonate, kaolin, bentonite, talc, starch, slotted ash, natural yellow (colored sand), wood powder, glass Fiber, epoxy resin, etc. Faced with such complicated production raw materials, how do plastic manufacturers realize production automation? Powder pneumatic conveying system is one of the important choices.   1. Classification of plastics According to the use of plastics, plastics can be divided into two categories: general-purpose plastics and engineering (modified) plastics. Currently, the popular degradable plastics on the market also belong to the scope of general-purpose plastics. General plastics mainly include polyolefins (PE, PO, PP, TPO, TPX, TPV, TPE, EVA, MMA), polyvinyl chloride (PVC, CPE), polystyrene (PS), phenolic plastics (bakelite powder, PF ), amino plastics, degradable plastics (bio-based, polylactic acid PLA, petroleum-based PBAT) six varieties. General-purpose plastics have large output, wide application and numerous products, which are found in all aspects of daily life. At this stage, as environmental protection is increasingly valued by the public, degradable plastics have gradually entered the public's field of vision, and degradable plastics are also commonly used in daily life, so they also belong to the category of general-purpose plastics. Engineering plastics are plastics that can be used as engineering structural materials and instead of metal to manufacture machine parts. For example polyamide (nylon, PA, PA6, PA66, PA46, PA12, PPA), polycarbonate (PC), polyoxymethylene (POM), ABS resin, polytetrafluoroethylene (PTFE), polyester (TPEE, TPU, PBT, PET), polysulfone (PSF, PSU, PES, PPS, PPSU), polyimide (PI, PEI), polyether ether ketone (PEEK), etc.   2. Raw materials for plastic production In addition to raw materials such as synthetic resins, plastic production also requires the addition of auxiliary materials. Different auxiliary materials have different functions to improve the performance of plastics, including: fillers, plasticizers, stabilizers, colorants, lubricants, etc. Auxiliary raw materials for powders and granules are: carbon black, white carbon black, black carbon black, titanium dioxide, calcium carbonate, kaolin, bentonite, talc, starch, slotted ash, natural yellow (colored sand), wood powder, glass fiber, epoxy resin etc. Liquid raw materials include: TOTM, DOP, DINP, DPHP, DOA, epoxidized soybean oil, white oil, DMC, ESO, paraffin oil, parabenzene, crude parabenzene, internal lubricant, external lubricant, etc.   Three, plastic production automation solutions In the face of the complex production materials in the plastics industry, pneumatic conveying technology has unparalleled advantages in conveying. Compared with traditional mechanical conveying methods, pneumatic conveying can achieve a higher degree of automation. With the automation system, it can be realized for plastic production enterprises. Automated manufacturing. Honggong can provide plastic manufacturers with: PVC powder pneumatic conveying, degradable plastic raw material conveying ingredients, rubber and plastic powder conveying ingredients, carbon black powder conveying, titanium dioxide pneumatic conveying, calcium carbonate powder conveying, kaolin powder conveying, bentonite powder conveying, talcum powder pneumatic conveying , starch pneumatic conveying, slotted ash pneumatic conveying, quantitative conveying of stabilizer ingredients, natural yellow (colored sand) pneumatic conveying, wood powder pneumatic conveying, glass fiber powder pneumatic conveying, epoxy resin powder pneumatic conveying, etc. For the automatic processing of various raw materials for plastic production, from unpacking and feeding, raw material storage, pneumatic conveying, metering and batching, automatic mixing, to the host and back-end equipment, Kerry has a wealth of case experience and can provide rubber and plastics enterprises. Provide a series of whole line planning solutions, and provide customers with one-stop service with the concept of safety, efficiency and environmental protection combined with professional skills.
