Q:How much is plastic PP5 resistant to cold?
The number 5 stands for PP plastic, or polypropylene plastic, non-toxic, tasteless and odorless, with a melting point of around 170
Q:What does "stress hardening" of plastic molding mean?
The plastic molding is various forms (such as powder, granules, solution and dispersion) of plastic products or parts required for the shape of.
Q:Are common plastic products in daily life, what are the materials?
PP, PE, and PVC are abbreviations of English names. The Chinese names are polypropylene, polyethylene and polyvinyl chloride. The English full name is polypropylene, polyethylene and polyvinyl chloride respectivelyThere is a P material in front of you will find a list of the upstairs English abbreviation, P is representative of "multiple polymerization", that is to say the general polymer or polymer are made of ordinary low molecular monomer polymerization.
Q:How do I see if the plastic cup is qualified?
As a result, the identification of plastic varieties has become simple and easy, and the cost of recycling has been substantially reduced. Today, many countries in the world have adopted the SPI logo scheme. China enacted almost identical labeling standards in 1996.
Q:Do all plastic products taste?
Polystyrene (non-toxic and harmless, the most common is the variety of plastic baskets, plastic barrels); phenolic resin (also called bakelite, nonflammable, high-temperature environment does not melt, used to make plug sockets and other electrical products. Most plastics are harmless, toxic and carcinogenic additives containing plastic, in order to improve the properties of various plastic products (plastic, coloring and thermal stability) need to add a variety of other substances, usually indicated in the product. To ensure safety, do not contact food with plastic of unknown material.
Q:How do you understand the level of engineering plastics?
Representative PS (polystyrene): This is used to make bowls, instant noodles boxes, foam snack box material, heat resistant, cold resistant, but can not be put into the microwave oven. Can not be used to hold strong acids (such as Liu Chengzhi), strong alkaline substances.
Q:How can plastics be produced, In several ways?
Press molding is also known as molding or pressing, and molding is mainly used for molding thermosetting resins such as phenolic resin, urea formaldehyde resin and unsaturated polyester resin.
Q:Can a plastic water cup be boiled in general?
7 cup of low plastic cup is made of polycarbonate, PC, used to call a bisphenol A material in the production process of PC material, PC material will be more or less in the presence of bisphenol A monomer, the higher the temperature, the faster speed of release.
Q:Plastic products in the injection process should pay attention to what?
When the material is formed, the molten material contacts the cavity surface and the outer layer is cooled immediately to form a low density solid shell. Because of the poor thermal conductivity of plastic, the inner part of the plastic part is cooled slowly to form a large solid layer with high density. Therefore, the wall thickness, cooling slow, high-density layer thickness is large contraction. In addition, the layout and number of inserts have direct influence on the direction of material flow, the density distribution and the shrinkage resistance. Therefore, the characteristics of plastic parts have great influence on the shrinkage size and direction.
Q:White plastic products used for a long time and yellow, how do?
There is a plastic yellow removal agent on the market. Its principle is to dissolve, remove the surface layer, and then cover a new layer of plastic, adding antioxidants to prolong the oxidation time. When the antioxidants are exhausted, the plastic will slowly turn yellow. But you can try.
