- Q: Low pressure plastic raw materials in the process of blowing the two sides of the fold, how to deal with?
- The blowing ratio is one of the control points of blown film production and! Refers to the ratio between the bubble diameter and the diameter of not blowing blowing after.
- Q: Plastic raw materials packaging is generally divided into several categories?
- A variety of kraft paper, polyethylene thick film, fiber bags, aluminum foil bags
- Q: Dissolve in 0.3 of the LDPE plastic raw materials what?
- The molecular structure of the conventional LLDPE is characterized by its linear backbone, with only a few or no long branched chains, but contains some short branched chains. Without long branched chains, the crystallinity of polymers is higher.In general, LLDPE resins are characterized by density and melt index. The density is determined by the concentration of comonomer in the polymer chain. The comonomer concentration determines the short branch chain in the polymer. The length of the short branched chain depends on the type of comonomer. The higher the concentration of comonomer, the lower the density of the resin. In addition, the melt index is a reflection of the average molecular weight of the resin, mainly determined by the reaction temperature (solution method) and the addition of chain transfer agents (gas phase method). The average molecular weight is independent of the molecular weight distribution, and the latter is mainly influenced by the type of catalyst.
- Q: What is the plastic bag made of?
- Method for identification of toxic plastic bags. The water detection method: put a plastic bag into the water, non-toxic can be surfaced, and poisonous won't rise; hand touch detection method: white or colorless transparent is non-toxic, the hand has a sense of lubrication, the surface like wax; color detection method: toxic haze or color yellow, red, black, feel sticky; jitter method: take a plastic bag shaking, crisp sound non-toxic; sound stuffy astringent toxic.
- Q: What are the raw materials needed for producing plastic hair dryer shell and flashlight shell?
- The shell materials are ABS and PAABS material is acrylonitrile (Acrylonitrile), 1, 3- (Butadiene) and styrene butadiene (Styrene) three kinds of graft copolymer monomer, ABS plastic molding temperature is 180-250 DEG C, but preferably not more than 240 DEG C, the resin will be decomposed.
- Q: Application of CPE in plastics industry
- Chlorinated polyethylene (CPE) for saturated polymer materials, the appearance of white powder, non-toxic and tasteless, has excellent weather resistance, ozone resistance, chemical resistance and aging resistance, good oil resistance, flame retardancy and coloring properties.
- Q: How do plastic materials come from?
- Plastic has good insulation for electricity, heat and sound: electrical insulation, arc resistance, heat preservation, sound insulation, sound absorption, vibration absorption, noise elimination, and excellent performancePlastic raw materials are extracted from some oil in the part of PC is most familiar with the material extracted from the oil, the PC material has a gasoline burning time; ABS is made from coal, ABS will show when soot like burn out; POM extraction from natural gas, POM will have a very smelly smell of gas when burned.
- Q: What plastic material is resistant to high temperature?
- High temperature resistant plastic material:PPS: (PPS)Polyphenylene sulfide (abbreviated as PPS) is a new type of high performance thermoplastic resin. It has the advantages of high mechanical strength, high temperature resistance, chemical resistance, flame resistance, good thermal stability and good electrical performance. It is widely used in the fields of electronics, automobile, machinery and chemical engineering
- Q: What are the raw materials needed for making plastic bags?
- The bags made of two materials each have their own characteristics, and are chosen according to the purpose and performance of the products. Polyethylene is petrochemical products, prices vary according to crude oil and market conditions every day, at present LDPE (high pressure polyethylene) offer at 13500 yuan. HDPE (low pressure polyethylene) at 11000 yuan up and down.
- Q: Is plastic raw material rubber?
- Raw materials are polymers of polymers such as polypropylene. Is generally from the fossil raw materials inside the extraction after polymerization together. A series of plastic refers to the resin as the main component, such as plasticizers, fillers, lubricants, additives such as colorants as auxiliary components, can flow in the process of forming materials. To put it simply, the oil was extracted and finally made into plastic, rubber and plastic
