General strength, but brittle, easy to produce stress cracking, not resistant to benzene. Not resistant to benzene, gasoline and other organic solvents. Suitable for the production of insulating transparent parts. Decorative parts and chemical instruments. Optical instruments and other parts. Molding performance: 1. Amorphous material, small moisture absorption, do not need to be fully dried, not easy to decompose, but the coefficient of thermal expansion is large, easy to produce internal stress. Good mobility, can be used screw or plunger injection molding machine.2. It is appropriate to use high material temperature, high mold temperature, low injection pressure, extend the injection time is conducive to reducing internal stress, prevent shrinkage. Available in various forms of gate, gate and molded parts arc connection, so as to avoid damage to the molded parts when going to the gate. Uniform wall thickness of the molded part, and even ejection of the molded part. The wall thickness of the molded part is even, and it is better not to bring inserts, if there are inserts should be preheated.

Use: recycled pet is mainly used for fibers, sheets, non-food packaging bottles, etc., the development of the use of construction materials, food packaging and containers, etc., the Japanese company has used polymer alloy to improve the technology will be recycled pet processed into a performance better than the use of new materials made of pet powder coating. Price: did not check the public offer, basically a single negotiation.

Treatment process: Japan Teijin developed a recycling method from the waste PET bottles DMT (dimethyl terephthalate) and EG (ethylene glycol), the first waste PET bottles crushed and cleaned, and then dissolved in EG, in the boiling temperature of the EG and the pressure of 0.1MPa, the PET for depolymerization, generating double a hydroxyethyl terephthalate (BHET). After filtration to remove the slag and additives, BHET reacts with methanol, and under the boiling temperature of methanol and the pressure of 0.1MPa, it undergoes an ester exchange reaction to produce DMT and EG. Then, after distillation, DMT and EG are separated, and then, through the process of recrystallization, DMT is purified; EG is purified through distillation, and the methanol can be recycled. The purity of both the recovered DMT and EG is 99.99%, and the cost of production is comparable to that of the generic DMT and EG method. DMT can be converted into pure TPA (terephthalic acid), which is used in the manufacture of bottle-grade PET resin. The recycling unit can generate about 10 percent of the feedstock the company uses to make resins.

What can be made from woven bags?

Response:

Thermoplastic manufactured products can be recycled and re-pelletized, called recycled plastics, which are called **recycled materials.

Theoretically, its use is slightly narrower than that of new material. Because of the recycling technology level and finished product use of special: such as food packaging, medical and so on (in order to avoid harm to the human body, generally such products do not use recycled materials).

But the advanced recycling technology and strict recycling system in developed countries have made the performance of recycled materials close to that of new materials, and even through the nature of the synthesis can be developed for new uses.

Domestic technology is backward, and so far, the recycled plastic pellets have not introduced enterprise standards or national standards. Therefore, the quality of plastic recycled material varies, and its use depends on its specific technical indicators.

According to the molecular structure of synthetic resins in plastics and thermal bear. Plastics can be 4

Species, one is thermoplastic plasticidae, the other is thermosetting plastics.

[1)The characteristics of thermoplastics

1)The molecules of the resin are linear or wen chain structure.

2) soften when heated, when it reaches a certain humidity is a molten state, become

flowable viscous mask, in a certain pressure can be formed into a certain shape,

cooling can be maintained after the shape has been molded. If heated again and can be softened, begin to

melt, repeated molding.

3) In the heating and cooling of the molding process only physical changes without chemical changes

chemical.

(2)Characteristics of thermosetting plastics.

1)The molecular structure of the resin.

2)At the beginning of heat. Tree Yin molecules are still linear structure, still has the plasticity of thermo

plastic plastics. When continue to heat, the linear molecular main chain breaks into the formation of chemical

Scientific chain bonding (i.e., crosslinking). Molecules are net shape structure, when the temperature reaches a certain value

when the molecules into a body structure, the tree is brittle transformed into neither baked nor dissolved not

re-change shape. Repeated heating is no longer softened, no longer plastic.

3) in the molding process both physical and chemical changes.

Thermoplastics are mainly polyethylene, polyvinyl chloride, ABS, polypropylene

polystyrene, nylon, formaldehyde, and so on.
