FAQ
- How many kinds of plastic raw materials are there? How to distinguish them?
- According to the nature of the plastic after heating, it is divided into thermoplastic and thermosetting plasticsThermoplastic molecular structures are linear structure, softening or melting when heated, plastic into certain shape, after cooling and hardening. When heated to a certain extent to soften after cooling and harden, this process can be repeated several times. Such as polyvinyl chloride, polyethylene, polystyrene and other thermoplastic. Plastic molding process is relatively simple, can continuous production, and has very high mechanical strength, so it is developing very quickly.The molecular structure of thermosetting plastics is the body structure, softening also occurs in heated, can plastic into a certain shape, but is heated to a certain extent or amount of curing agent, hardened stereotypes, re heating become soft and will not change shape. The thermosetting plastic processing molding after heating no softening, and therefore can not be recovered then, such as phenolic, amino plastics, resin and other plastic. These are thermosetting plastic molding process is more complex, so the continuous production is difficult, but its good heat resistance, not easy to deformation, and the price is relatively low.
- What are the raw materials for producing plastic films?
- Film type: PVA coated high barrier film, biaxially oriented polypropylene film (BOPP) and low density polyethylene film (LDPE), polyester film (PET), nylon film (PA), polypropylene (CPP) film, etc..
- How is plastic material made out?
- The main components of plastic resin (in the early stage of coal tar products and calcium carbide carbide, it is used for oil and natural gas products, such as ethylene, propylene, benzene, formaldehyde and urea).
- What are the materials for making plastic buckets? How many are there?
- There will not be a big gap, and some materials are good toughness, and some of the high strength, the original particles are basically not much difference. If it's recycled, that's hard to say.
- Aluminum Alloy door corner with what plastic raw materials do?
- If the diagonal code requirements are not high, you can arbitrarily first a PP material.
- What are the APP of plastic raw materials?
- Thermosetting plastics (phenolics, epoxy resins, unsaturated polyesters, polyurethanes, silicones, amino resins, etc.);
- What is the disposable transparent plastic cup?
- PC: colorless transparent material, suitable for making instruments, small parts, insulation, transparent parts and impact parts.Transparent ABS, this material is expensive, in the field of decoration, packaging and other promising.
- What is the material of plastic flat screen?
- It is made of hot spraying and cold fixing. It has the characteristics of wear resistance, corrosion resistance, toughness and so on. It can be used as a substitute for wire. The utility model has the advantages of corrosion resistance, light weight, long service life, no poison, no smell and good transparency.
