- Q: What material is best for plastic gears?
- Gears can be made of PA, POM, etc., but PA and POM will have noise at high speeds.
- Q: Is plastic bucket and plastic bottle the same raw material?
- When the number of the triangle in the bottom of the barrel is "4", the main component of this kind of plastic barrel is low-density polyethylene, also called LDPE. Such plastic barrels of heat resistance is not strong, in case of high temperature, there will be hot melt phenomenon, will produce some of the body can not be decomposed plastic preparations, may cause breast cancer, neonatal congenital defects and other diseases.
- Q: Plastic PPT30S add what material will increase hardness?
- In general, this material will be grafted with PP-G, POE, increase the impact, plus stone powder, glass fiber, mica powder, increase hardness.
- Q: What is the difference between PA66 and PA6 plastic raw materials? Differences in price, color, performance, etc
- PA66 (polyamide 66 or nylon 66) is more widely used in the automotive industry, instrument shells, and other products that require impact resistance and high strength than PA6, PA66.
- Q: What are the plastic raw materials?
- This polymer is made up of many smaller and simpler molecules made of covalent bonds. There are many kinds of polymers, one is to change the Prajna heat to classification, it can be divided into two categories.
- Q: That kind of plastic bottle blows well
- PPEspecially the soft material, good toughness, non-toxic, high temperature resistant, often make catering appliance or other high-temperature product packaging; but the plasticity, processing difficulty, surface gloss and color processing, will be lighter, used to make disposable plastic bottles
- Q: What machines and materials are needed for the manufacture of disposable plastic cups?
- Crusher is a large size of solid materials crushed to the required size of the machine. The crusher is composed of coarse crushing, fine crushing, pneumatic conveying and so on. It achieves the purpose of crushing in the form of high-speed impact. The use of wind power as a single powder eliminates traditional screening procedures.
- Q: What kind of plastic material is used for medical instruments?
- Because most monomers and their oligomers are poisonous, medical plastics have strict restrictions on the residues of these substances;
- Q: PVC what is the difference between raw and recycled raw materials?
- Because the recycled material is a result of high temperature dissolved, it is likely to emit a pungent flavor, this odor may be harmful to humans.
- Q: What are the heavy bags in the plastic material?
- (polypropylene) English Name: Polypropylene, PP plastic concept, proportion polypropylene, also includes propylene and a small amount of ethylene copolymer. PP granular material is natural, cylindrical particles, smooth particles
