- Q: What is the concept of plastic raw materials for turnover containers?
- Suzhou Ke Reed plastic turnover box made of polypropylene, polyethylene synthesis, light weight, long service life, safety, non-toxic, tasteless, moisture-proof, corrosion resistance, light weight, durable, can be stacked, rich color, pure etc..
- Q: How many types of plastic materials are there?
- There are many kinds of plastics. So far, there are about more than 300 kinds of plastic produced in the world. Many classification methods of plastic, there are two kinds of commonly used: 1, according to the nature of the heated plastic divided into thermoplastic and thermoset plastic molecular structure are linear structure, softening or melting when heated, plastic into certain shape, after cooling and harden. After heating to a certain extent, it softens again and hardens again after cooling. This process can be repeated many times. Such as PVC, polyethylene, polystyrene and so on. Thermoplastic molding process is relatively simple, can be continuous production, and has a high mechanical strength, so the development of very fast. 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 will not soften and change the shape of the. Thermosetting plastic processing, molding, the heat is no longer softening, and therefore can not be recycled, such as phenolic plastics, amino plastics, epoxy resin, etc. belong to this kind of plastic. Thermosetting plastic forming process is more complex, so continuous production has some difficulties, but its good heat resistance, not easy to deformation, and the price is relatively low.
- Q: How to use all kinds of plastic materials?
- ABS acrylonitrile butadiene styrene copolymerABS acrylonitrile (chemical corrosion resistance, surface hardness of butadiene styrene) (toughness) (good processability, good dyeing weatherability, easy oxidation) with good comprehensive performance, high impact toughness and good mechanical properties, excellent heat resistance, oil resistance and chemical stability, stable size, easy to machine processing, surface plating, good electrical properties.Suitable plastic products: for general structures or wear resistant transmission parts and corrosion protection equipment. Gears, pumps, impellers, bearings, handles, pipes, motors, housings, electronic parts, clocks and watches, water tanks, freezers, refrigerators, housings, stationery, toys
- Q: 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.
- Q: What is the plastic bag made of?
- The main raw material of plastics is oil and natural gas, that is, carbon hydrogen compounds. First, the appropriate macromolecular components in petroleum and natural gas are extracted, first split into monomers, and then polymerized into polymers to become plastic
- Q: What kinds of plastic properties can be divided into thermal properties?
- Classification of plastics (100 million nylon)There are many kinds of plastics. There are many kinds of classification methods. They are usually divided into two categories: thermoplastic and thermosetting plastics according to the change of their properties after heating.
- Q: How to test plastic raw materials?
- Thermal stability test of size and appearance quality. Place the product in a 8020C oven, 24H, and cool down to 2350C (2H). Measure the size of the same measuring point before and after the test, and calculate the percentage change rate. And observe the appearance quality changes, dimensional change rate of <0.2%, appearance is not allowed to have deformation, crack, expansion, surface gray, discoloration and other phenomena.
- Q: What's the shell of the relay? What exactly is plastic?
- It is by virtue of this characteristic of molding, the use of the first heating of the plastic flow, under pressure filled cavity, and then solidified into a shape and size of the product. Thermosetting resins are linear or branched before curing, forming a chemical bond between the molecular chains after curing, becoming a network of three degrees, not only without melting, but also insoluble in solvents. Bakelite, formaldehyde, melamine, formaldehyde, epoxy, unsaturated polyester and silicone plastics are all thermosetting plastics. Mainly used for heat insulation, abrasion resistance, insulation, high voltage resistance in the harsh environment of the use of plastic, mostly thermosetting plastic, most commonly used should be wok, pot handle and high and low voltage appliances.. Commonly used thermosetting plastics are phenolic resin, urea formaldehyde resin, melamine resin, unsaturated polyester resin, epoxy resin, silicone resin, polyurethane and so on
- Q: What are the raw materials for producing plastic films?
- Plastic film raw materials are: PVC, polyethylene, polypropylene, polystyrene and other resins.
- 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..
