The chemical name of waste plastics, and what kind of plastic products can be made after various waste plastics are made into granules. Reply: Reply: Reply: ABS.PS.PP.PE and other material properties of the main purpose and the difference between the various labels. Reply: PS electrical insulation (especially high frequency insulation) is excellent, colorless and transparent, light transmittance is second only to plexiglass, coloring water resistance, good chemical stability, general strength, but brittle, easy to produce stress embrittlement, Not resistant to benzene. Gasoline and other organic solvents. Suitable for the production of transparent insulation. Decorations and chemical equipment. Optical instruments and other parts. PE is basically divided into three categories: high-pressure low-density polyethylene (LDPE), high-density polyethylene (HDPE), and linear low-density polyethylene (LLDPE). The film is the main processed product, followed by sheet and coating, hollow containers such as bottles, cans, and barrels, and other various injection and blow molding products, pipes, and insulation and sheathing of wires and cables. Mainly used in packaging, agriculture and transportation departments. Pp is cheap, light, and has good processability and versatility. The development of catalysts and new processes has further promoted the expansion of applications. Some people say: “As long as there is a plastic substitute for the material of one product, then polypropylene is used for this product. potential". Main uses: woven bags, tarpaulins, durable consumer goods such as automobiles, home appliances and carpets.

For example, what can be done after making mineral water bottles into pellets? Its chemical name?
What can I do after woven bags are made into granules?
After thermoplastics are recycled, they can be re-granulated, called recycled plastics, whose name is **Recycled.
In theory, its use is slightly narrower than new material. Because of the particularity of the technical level of recycling and the use of finished products: such as food packaging, medical treatment, etc. (In order to avoid harm to the human body, such products generally do not use recycled materials).
However, the advanced recycling technology and strict recovery system in developed countries have brought the performance of recycled materials to new materials, and even new uses can be developed through such properties as synthetics.
Domestic technology is lagging behind, and so far, recycled plastic particles have not introduced corporate standards or national standards. Therefore, the quality of plastic recycled materials is uneven, and its use depends on its specific technical indicators.
What PP material is used for the syringe? Can it be recycled? How much is a ton?
The PP material used for the syringe is a kind of random copolymer PP, which can be recycled. The current price of about 13,000 tons of waste-containing syringes is medical waste, and it should be used with caution to avoid damage.
Some netizens recommend South Korea's RP340R (MI25) or 370Y (MI18); and it is strongly recommended that you do not use recycled materials because it is very easy to cause medical accidents. .
What is the daily oil price of Brent, WTI, and OPEC? How is the oil price analyzed? At the same time, how does the futures level of oil look at whether the plastic trend is high or low?
Due to the principle of cost promotion, crude oil, naphtha, ethylene, polyethylene, and plastic products, the price of crude oil is consistent with the trend of plastics (short-term deviation is also normal), but this effect should theoretically be A certain hysteresis effect is not as sensitive as the current domestic plastic market. At present, the international oil price brings about the main influence of the mentality on the domestic plastics market, and a kind of herd mentality.
When the market returns to rationality, the supply and demand of plastic itself will have an increased impact on market prices.
ABS has good rigidity, high impact strength, heat resistance, low temperature resistance, chemical resistance, mechanical strength and electrical properties, easy processing, processing dimensional stability and surface gloss, easy Coating, coloring, can also be sprayed metal Secondary processing properties such as electroplating, welding, and bonding. Main applications: Automotive, Appliances, Electronics/Electrical, Building Materials, ABS Alloys/Blends
PS material and ABS material performance difference?

PS plastic (polystyrene), material properties: excellent electrical insulation (especially high-frequency insulation), colorless and transparent, light transmittance second only to plexiglass, coloring water resistance, good chemical stability, strength, However, it is brittle and easily embrittled. It is not resistant to benzene, gasoline and other organic solvents. It is suitable for the production of insulating transparent parts, decorative parts and chemical instruments, optical instruments and other parts. Forming properties: 1. Amorphous material, moisture absorption is small, not Must be fully dry, not easy to decompose, but the coefficient of thermal expansion is large, easy to produce internal stress. Liquidity is good, can be used screw or plunger injection molding machine. 2 should use high material temperature, high mold temperature, low injection pressure, extend the injection Time is conducive to reducing internal stress and prevent shrinkage. Deformation. 3. Available in various forms of gate, gate and plastic parts arc connection, so as not to damage the plastic parts at the gate. Mold release slope, top out evenly. The thickness of the plastic parts is even and it is better not to insert the inserts. If there are inserts, they should be warmed up.
ABS (Acrylonitrile Butadiene Styrene) is a light yellow granular or beaded opaque resin that is non-toxic, odorless, and has low water absorption. Has excellent physical and mechanical properties, excellent low temperature impact resistance, excellent electrical properties, abrasion resistance, dimensional stability, chemical resistance, dyeing. Easy to process and shape. ABS water, inorganic salts, alkalis and acids, insoluble in most alcohols and hydrocarbon solvents, soluble in aldehydes, ketones, esters and some chlorinated hydrocarbons. The disadvantages of ABS are flammability, low heat distortion temperature, and poor weather resistance. Combustion characteristics: flammable; continue to burn from the fire; flame yellow, thick black smoke; softening, foaming; Solubility: soluble solvent: dichloromethane; insoluble solvent: alcohols, aliphatic hydrocarbons, water. Applications: automotive industry, machinery and equipment, electronic and electrical appliances.
What is the English code of the waste acrylic? What is the current price of scrap?
Acrylic is a special kind of organic glass.
PMMA is commonly known as plexiglass, also known as acrylic or acrylic, and Hong Kong people are more commonly known as Acrylic. It is an important thermoplastic material that was developed earlier. It has good transparency, chemical stability and weatherability, and is easy to dye and easy to use. Processing, beautiful appearance, has a wide range of applications in the construction industry.
The price of transparent acrylic waste is about 10,000; due to the close of the year, the acrylic waste market is out of stock.
I want to build a recycled plastic pellet plant, but I don't know what kind of material the woven bags belong to, such as PP and ABS.
