Q: Plastic pipe gas temperature 150 degrees, plastic pipe surface problems?: Plastic pipe is usually plastic resin as raw material, adding stabilizers, lubricants, etc., to "plastic" method in the pipe mill by extrusion processing. Because of its light weight, corrosion resistance, beautiful appearance, no bad smell, easy processing, convenient construction and other characteristics, it has been more and more widely used in building engineering. Mainly used for building construction of the water supply system, piping, drainage, exhaust and sewage sanitary pipe, underground drainage pipe system, storm pipe and wire installation supporting the use of threading tubes, and so on.

Q: What are the raw materials of foam plastics and how do they come out?: The foaming agents for epoxy resins are two types: physical foaming agents and chemical foaming agents. Physical foaming agents are mainly low boiling liquid, such as three chloro methane (F11), three chlorine, three fluorine ethane (F112), two chlorine, two fluorine methane (F12) and so on. By using the curing heat of the epoxy resin, the liquid with low boiling point is evaporated, and the gas is released, and the products are small in density and low in thermal conductivity. But fluorine hydrocarbons have a damaging effect on the atmosphere and are often used to spray foaming processes. According to the experts of China epoxy resin industry association, toluene and so on can be used as auxiliary foaming agent. In addition to foaming, it also acts as a curing reaction, a heat absorber and a diluent.

Q: The difference between resin and plastics: Resin material: it is natural, extracted from plants, the cost is higher. Plastic: it is chemical material, extracted from petroleum, Chen is lower

Q: What is the material of plastic dip?: Immersion is a plastic coating process, that is, the plastic coating on the substrate (usually metal), such as: our daily clothes racks, pliers handle, scissors on the rubber sleeve, handrails and so on. According to whether need to be heated into hot dip and cold plastic raw materials, in accordance with the dip to points can be divided into liquid dip and dip powder.

Q: What material is plastic bag made of?: Polyethylene (Polyethylene, PE), referred to as PE. It is a high molecular organic compound which is made up of ethylene. Polyethylene is recognized as the best food for contact with food in the world. Non-toxic, tasteless, odorless, in line with food packaging hygiene standards. Polyethylene film, light and transparent, with moisture-proof, anti - oxygen, acid, alkali, air tightness, heat sealing and other outstanding performance. Known as "plastic flowers" laudatory title. It is the most important and most important material in plastic packaging and printing.

Q: How do plastic raw materials trade? How big is the market?: At home, the whole plasticizing industry chain is almost 3 trillion of the big market, and the annual growth rate of 20%.

Q: What is the essential difference between plastic raw materials and engineering plastics?: engineering plasticIt's a kind of plastic, and a universal plastic.Like everyday things, what barrels, pots, plastic, etc?.Engineering plastics generally have many properties that are not common in plastics. They are often used in construction machinery to replace certain metals.Plastic is resin and filler, so it is usually granular. Raw materials too. Only a few powdery.

Q: Application of CPE in plastics industry: Resin type CPE in the product is also known as "A" material, elastic rubber type CPE has become B type material!Application: in the late 1990s, the domestic demand for high-performance flame-retardant rubber is increasing, especially the development of wire and cable industry and auto parts manufacturing industry, which has led to the consumption demand of rubber based CPE. Rubber based CPE is a kind of special synthetic rubber with good comprehensive properties, heat resistance, ozone aging and good flame retardancy.Mainly used in wire and cable (coal mine cable, UL and VDE standards such as the provisions of the wire), hydraulic hose, hose, adhesive tape, rubber sheet, PVC profiles, pipe modification, magnetic materials, ABS modification, and so on.

Q: PP plastic stool surface with those raw materials, what is the ratio?: In general plastics, PP has the best heat resistance, and its thermal deformation temperature is 80-100 DEG C and can be boiled in boiling water.

Q: What is the raw material for producing high temperature polyethylene plastic bags?: High density polyethylene (HIGH DENSITY, POLYETHYLENE, HDPE) commonly known as low-pressure polyethylene, compared with LDPE and LLDPE, with high temperature resistance, oil resistance, vapor permeability and resistance to environmental stress cracking resistance, and electrical insulation and shock resistance and cold resistance is very good, mainly used in blow molding, injection molding etc..
