Nylon, polyamide, acetal, resin, polyester, acrylic, polyurethane, vulcanized rubber, elastomer, polyester rubber, polycarbonate, polysulfone, polyethylene, rubber, polyetherketone, polypropylene, polystyrene, phenolic resin, polyvinyl chloride, microsilicon. ... There are currently over 300 different types of plastic produced in world, why are there so many? Because plastic we use is not a single substance, but consists of many raw materials.
The production of plastics is inseparable from auxiliary materials and additives, soot, white soot, black soot, titanium dioxide, calcium carbonate, kaolin, bentonite, talc, starch, slit ash, yellow earth (colored sand), wood. Powder, fiberglass, epoxy, etc. Faced with such a complex production of raw materials, how do plastic manufacturers implement production automation? The pneumatic powder conveying system is one of important options.
1. Plastic classification
According to use of plastics, plastics can be divided into general-purpose plastics and engineering (modified) plastics. At present, degradable plastics that are popular on market are also classified as general-purpose plastics.
General purpose 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, PLA based on polylactic acid, PBAT based on petroleum) six varieties. General purpose plastics have a large production volume, wide application and numerous products that are found in all areas of daily life. At this stage, when environmental protection is attracting more and more public attention, degradable plastics are gradually coming into public eye. Degradable plastics are also widely used in daily life, so they are also classified as general purpose plastics. .
Engineering plastics are plastics that can be used as engineering construction materials and instead of metal to make machine parts. Such as polyamide (nylon, PA, PA6, PA66, PA46, PA12, PPA), polycarbonate (PC), polyoxymethylene (POM), ABS, polytetrafluoroethylene (PTFE), polyester (TPEE, TPU, PBT, PET), polysulfone (PSF, PSU, PES, PPS, PPSU), Polyimide (PI, PEI), Polyetherketone (PEEK), etc.
2. Raw materials for plastic production
In addition to synthetic resin and other raw materials, production of plastics also requires addition of auxiliary materials. Various auxiliary materials perform different functions to improve performance of plastics, including: fillers, plasticizers, stabilizers, colorants, lubricants, etc.
Auxiliary raw materials for powder and granules include: carbon black, white carbon black, black carbon black, titanium dioxide, calcium carbonate, kaolin, bentonite, talc, starch, slit ash, yellow earth (colored sand), wood flour. , fiberglass, epoxy resin, etc. Liquid raw materials include: TOTM, DOP, DINP, DPHP, DOA, epoxy soybean oil, white oil, DMC, ESO, paraffin oil, p-benzene, raw p-benzene, internal lubricant, external lubricant, etc.
3. Plastics Automation Solutions
