- Q: What are the concepts, classifications and distinctions of modified plastics and plastic materials?
- Modified plastics should, in principle, be made from the plastic raw materials produced by petrochemical plants. By adding plastic additives, they can enhance their hardness, fire resistance, high temperature or low temperature, weather resistance and ultraviolet resistance. Therefore, modified plastics are processed from plastic raw materials, which is the relationship between source and flow.
- Q: What is the difference between PPA plastic raw material and PP?
- PPA is a high temperature nylon, generally used in the automotive industry and the electrical and electronic industry, it has the characteristics of high temperature resistant nylon, but also much higher than nylon, that is to say in the high temperature working environment inside it will be more excellent performance than ordinary nylon, longer service life. At present, the high temperature nylon base material on the market is basically nylon 46, nylon, 6T, 9T and so on.
- Q: Plastic PPT30S add what material will increase hardness?
- Commonly used talc and calcium carbonate increase the flexural modulus rather than the surface hardness. To increase surface hardness, a nucleating agent can be used. Moreover, talc and calcium carbonate can not be added to the injection molding, you must use the pumping equipment.
- Q: What are the APP of plastic raw materials?
- General plastics (polyethylene, polypropylene, polyvinyl chloride, polystyrene, ABS, etc.), thermosetting plastics (phenolic resin, epoxy resin, unsaturated polyester, polyurethane, silicone, amino resin, etc.);
- Q: How to make plastic raw materials?
- Cracking is in the process of petrochemical production, which is higher than the cracking temperature (700 DEG to 800 DEG C, sometimes even more than 1000 degrees Celsius), making oil fractionation products (including petroleum gas) long chain hydrocarbon in the fracture process into short chain hydrocarbons such as ethylene and propylene.Cracking is a much deeper cracking. The chemical process of oil cracking is more complex, generated by pyrolysis gas is a mixture of complex components, in addition to the main products of ethylene, and propylene, isobutene and methane, ethane, butane, acetylene, hydrogen sulfide and carbon oxides. After the pyrolysis gas is purified and separated, the basic organic chemical materials such as ethylene and propylene can be obtained with the required purity. At present, petroleum cracking has become the main method of producing ethylene.
- Q: What are the specific differences between plastics and plastics?
- Plastic raw materials are extracted from some oil in the most familiar part of PC material (polycarbonate) is extracted from the oil, the PC material has a gasoline burning time; ABS (acrylonitrile butadiene styrene plastic) is made from coal, ABS a soot like when burn out; POM (polyoxymethylene plastic) is made from natural gas, POM will have a very smelly smell of gas in the burn time.
- Q: What plastic material is used for plastic hose?
- PVC: the main ingredients of PVC, bright color, corrosion resistant, durable, due to an increase in the manufacturing process of plasticizer, anti aging agent and other toxic and auxiliary materials to enhance its heat resistance, toughness, ductility, so their products generally do not store food and drug. If there is special physical property requirements, you can also increase the amount of modifier. It must not add a plasticizer has good tensile and compressive strength, but its flexibility is better than other plastic pipe, excellent corrosion resistance, the cheapest price in all kinds of plastic pipe, but low temperature brittle adhesive, rubber ring socket flange connection, threaded connection for residential living, industrial and mining industry and agriculture for drainage, irrigation, gas supply, exhaust pipe, wire pipe, rain water pipe, industrial anti-corrosion pipe etc.. The heat resistant property is outstanding, the thermal deformation temperature is 100 DEG C, the chemical resistance is excellent, and the connecting flange screw thread is connected with the hot water pipe
- Q: Plastic raw materials are granular, why not powder?
- Who says plastic raw materials are granular?.
- Q: ABS plastic storage conditions
- Plastic materials generally react with light and oxygen for a long time to become yellow and brittle
- Q: What material do you need for plastic film? Do you use this material?
- Plastic bags, quality, food grade requirements, the use of brand new HDPE (low pressure polyethylene).
