Answer:

Purposes: mainly used for regeneration of pet fiber, sheet, non-food packaging bottles, the use of the development: building materials, food packaging and containers, the Japanese company has taken advantage of the polymer alloy improved technologies to renewable pet processing into a performance superior to pet a new material manufactured by powder coating. Price: not found a public offer, is basically a single meeting.

Process: Japan’s Teijin has developed a waste PET bottle, the DMT (dimethyl terephthalate) and EG (ethylene glycol) cycle, the first waste PET bottle crushing and washing, and then dissolved in EG EG boiling point temperature and 0.1MPa pressure, PET depolymerization, generating double a terephthalic acid hydroxyethyl methacrylate (BHET). And then filtered to remove residues and additives, BHET reacts with methanol, the methanol boiling point temperature and 0.1MPa pressure after the transesterification reaction of DMT and EG. After distillation, the DMT and EG were separated, and then by recrystallization process, DMT refined; EG was purified by distillation, methanol can be recycled. Recovery of DMT and EG purity of 99.99%, comparable to the cost of the production costs and general DMT and EG method. DMT can be converted into pure TPA (terephthalic acid), used to make bottle-grade PET resin. Circulation device can generate about 10 percent of the company’s production of the raw material of resin used.

Press the plastic synthetic resin molecular structure and thermal Bear. Plastic can be

, A thermoplastic Division, another is a thermosetting plastic.

1) the characteristics of the thermoplastic

1) resin molecular structure was linear or text chain.

2) when heated to soften, when you reach a certain humidity was molten state, as

Can the flow of viscous bunker, under certain pressure can be formed into a certain shape,

Forming the shape after cooling can be maintained. If re-heating can be softened, beginning

Financial, repeated forming.

3) in the forming process of heating, cooling only physical change and no chemical change

Of.

(2) the characteristics of thermosetting plastics.

Figure 1) resin molecular structure.

2) the beginning of heating. The shade of molecules continued to show a linear structure, still has a hot

Plastic plastic plasticity. Continue heating, linear main chain break formation of

School chain binding (crosslinking). Molecules showed a net-shaped structure, when the temperature reaches a certain value

Molecules into the body structure, tree brittle transition neither baking melt without dissolved

And then change the shape. Repeat no longer soften when heated, no longer has plasticity.
