Q:How many kinds of plastics are there?
PC: commonly known as polycarbonate. The variety is also a transparent material, high surface hardness, scratch resistance, strong impact resistance, high strength, good weather resistance (that is not afraid of the sun). The furniture is the sunshine plate screen baffle material hollow extrusion molding. Features: high price cost, about PMMA higher than about 40%.
Q:Scope and characteristics of plastics No. 7
Plastic No. 7 represents polycarbonate (PC), other plastic products. PC is a widely used material, especially for bottles and space cups, which is controversial because it contains bisphenol A. Experts point out that, in theory, as long as the process of making PC, bisphenol A percent into plastic structure, it means that the product is not bisphenol A, let alone release. However, if a small amount of bisphenol A is not converted into a plastic structure of PC, it may be released into the food or drink.
Q:What does the plastics factory mainly produce?
The main component of PVC is mainly polyvinyl chloride and poly vinyl alcohol (vinyl chloride). The English abbreviation is PVC. PVC plastic products in the processing of long mixed lubricants, stabilizers and other ingredients, so it is not used as a general food packaging. But the PVC bag has the advantages of high strength, non flammable, change of resistance to climatic conditions and excellent physical stability, is China's plastic products industry is a product of the maximum yield. PVC is often processed into all kinds of clothing, books, electrical appliances, metal products, packaging bags, light industry sector has a wide range of applications.
Q:What plastics are environmental protection materials now?
Water degradation plastic: adding water absorbent material in plastic, when used up, it can be dissolved in water. It is mainly used in medical and sanitary equipment (such as medical gloves), so it is easy to destroy and disinfect.
Q:Is the resin material of imitation jade handicraft Plastic?
Broadly speaking, any polymer compound that can be used as plastic material for processing raw materials is called resin. Resin is the main raw materials for the manufacture of plastics, paint is also used the system (the main film-forming material, coating such as alkyd resin, acrylic resin, synthetic fatty acid resin, the resin in the Yangtze River Delta and Pearl River Delta are also relatively strong in the paint industry, such as Changxin chemical, Nuplex resin, three resin, Ying DSM syntech resins), adhesives, insulating material, synthetic resin in industrial production, is widely used in separation and purification of impurities in liquid, with macroporous adsorption resin, ion exchange resin, and some special resin.
Q:What harm does it take to eat hot food with plastic?
If a plastic bag containing more than 50~60 degrees of food is used, the lead in the bag will dissolve into the food, and the plastic bag will release poisonous gas and invade into the food. Long term intake of the human body can seriously impair health and cause disease. Especially hot food, high temperature will make the poisonous substances in plastic absorbed by food, once entered the body will cause accumulation of towel poison, so when the hot food, must not mess with plastic bags.
Q:What type of plastics do you have?
According to the molecular structure and thermal properties of synthetic resins in plastics, plastics can be divided into two types, thermoplastics and thermosetting plastics.(1) the characteristics of thermoplastics1) the resin molecules are linear or branched.2) softening when heating, when reaching a certain temperature, melting state, become a flow of viscous fluid, under certain pressure can be shaped into a certain shape, after cooling can maintain the shape has been formed. If heated again, it can be softened, melted and formed again and again.3) in the process of heating and cooling, it is mainly physical change, and in a few cases there are chemical changes.
Q:POM plastic flower mold how to solve?
Terms of settlement:1, the raw materials in the drying machine to fully dry and then production.2, reduce the size of the pipe, especially the nozzle temperature.3, slow down the speed of the injection.4. Adjust the position of the spray glue accordingly.
Q:What if the plastic is broken?
The hot connection relatively rough surface hot plate welding connection way prone to flash, it is necessary to carry out the follow-up processing rotating welding method is applicable to the two connecting part is in the shape of thermoplastic resin products round, does not need to use adhesive glue, solvent or external heat.
Q:The use of various plastic materials?!
GPPS modified polystyrene 204The transparency of 88-92%, refractive index 1.59-1.60, suitable for light products, dyeing is strong, non-toxic and tasteless, no fungus growth, high impact strength, resistance to acid and alkali resistant performance is good, not on the basis of solvent, excellent electrical properties, easy molding, moisture less than 0.02% can maintain the strength and size of high humidity, but the brittleness.Suitable plastic products: decorations, lighting signs, lampshades, stationery, transparent toys, daily necessities, instrument lenses, freezers and thermal insulation in the refrigerator (after foaming).
