Suitable for making insulating transparent parts, decorative parts, chemical instruments, optical instruments and other parts. Moldability: 65438. It does not need to be fully dried and is not easy to decompose, but it has a large thermal expansion coefficient and is easy to generate internal stress. It has good fluidity and can be molded by screw or plunger injection molding machine. 2. High material temperature, high mold temperature and low injection pressure should be adopted to reduce internal stress and prevent shrinkage deformation. 3. Various gates can be used, and the gates can be connected with the plastic parts in an arc shape to avoid damaging the plastic parts when disassembling the gates. The demoulding slope is large and the ejection is uniform.
ABS (Acrylonitrile-Butadiene-Styrene) is a pale yellow granular or beaded opaque resin, which is non-toxic, tasteless and low in water absorption. It has excellent physical and mechanical properties, excellent low-temperature impact resistance, excellent electrical properties, wear resistance, dimensional stability, chemical resistance and dyeability. Easy to process and shape. ABS is resistant to water, inorganic salts, alkali and acid, insoluble in most alcohols and hydrocarbon solvents, but soluble in aldehydes, ketones, esters and some chlorinated hydrocarbons. The disadvantages of ABS are flammability, low thermal deformation temperature and poor weather resistance. Combustion characteristics: flammable; Keep burning away from fire; Yellow flame, thick black smoke; Softening and foaming; Acrylonitrile smell. Solubility: Soluble solvent: dichloromethane; Insoluble solvents: alcohols, aliphatic hydrocarbons, water. Applications: automobile industry, mechanical equipment, electronic appliances, etc.

22. What is the use, price and treatment technology of waste PET?
Reply:
Uses: Recycled pet is mainly used for non-food packaging fibers, sheets, bottles, etc. Its development uses include: building materials, food packaging and containers. Japanese companies use polymer alloy improvement technology to process recycled pet into powder coatings with better performance than new pet materials. Price: No public quotation was found, and it was basically a single negotiation.
Treatment process: Teijin Company of Japan has developed a method to recover DMT (dimethyl terephthalate) and ethylene glycol (ethylene glycol) from waste polyester bottles. First, the waste PET bottles were smashed and cleaned, and then dissolved in EG. At the boiling temperature of EG and the pressure of 0. 1MPa, PET depolymerized to produce Shuang Yi hydroxyethyl terephthalate (BHET). After filtration, the filter residue and additives were removed, so that BHET reacted with methanol, and transesterification was carried out at the boiling temperature of methanol and the pressure of 0. 1MPa to generate DMT and EG. After distillation, DMT and ethylene glycol were separated, and then DMT was refined by recrystallization. Ethylene glycol is purified by distillation, and methanol can be recycled. The purity of recovered DMT and EG reaches 99.99%, and the production cost is equivalent to that of ordinary DMT and EG methods. DMT can be converted into pure TPA (terephthalic acid), which can be used to make bottle-grade PET resin. The circulating device can produce about 10% of raw materials for resin production in our company.

What can I do after the woven bag is made into particles?
Reply:
Thermoplastic products can be granulated after recycling, which is called recycled plastics, and its name is * * recycled materials.
Theoretically, its use is slightly narrower than that of new materials. Because of the technical level of recycling and the particularity of finished products, such as food packaging and medical care. (In order to avoid harm to human body, generally this kind of products do not need to recycle materials).
The advanced recycling technology and strict recycling system in developed countries make the properties of recycled materials close to new materials, and even new uses can be developed through this property and synthesis.
Domestic technology is backward, so far there is no enterprise standard or national standard for recycled plastic particles. Therefore, the quality of plastic recycled materials is uneven, and its use depends on its specific technical indicators.

38. How to analyze the daily oil prices of Brent, WTI and the Organization of Petroleum Exporting Countries, and how to see whether the future plastic trend is high or low?
Reply:
Affected by the cost-driven principle: crude oil-naphtha-ethylene-polyethylene-plastic products, the price of crude oil is consistent with the general trend of plastics (short-term deviation is also normal), but this influence should have a certain lag effect in theory, which is not as sensitive as the current domestic plastic market. At present, the impact of international oil prices on the domestic plastic market is mainly the influence of mentality and the role of herd mentality.
When the market returns to rationality, the relationship between supply and demand of plastics itself will have a greater impact on the market price.
