Application of recycled plastic products - injection molding

As the plastic recyclable other material contaminated by the degree of difficulty and different from removing contaminants, such as glass, metal. Pollutants are often difficult to penetrate the glass, and internal metallic material, very easy to penetrate to the interior plastics, plastic pollution. Even if mixed with glass and metal contaminants can easily be removed at up to several hundred degrees or even thousands of regeneration temperature; however, recycled plastics, low temperature, typically only about 200 degrees, it is difficult to remove contaminants. Therefore, no matter how fine the regeneration process in the recycled plastic will be a certain level of residual contaminants.

Can the physical characteristics of plastic injection molding machines after the thermoplastic molding their secondary processing into thermoplastics and thermosetting plastics, this process is suitable only for injection molding machines available for secondary processing of thermoplastics, such non-crystalline plastic separator crystallinity categories. Highly crystalline plastic mechanical strength, heat resistance, but poor transparency, a plastic such as polyethylene, polypropylene, polybutene-1, poly-4-methylpentene-1, polyoxymethylene, polyamide, polyester, polyvinylidene chloride, fluorine plastic, chlorinated polyether. Non-crystalline plastic mechanical strength is poor crystalline plastic, but the heat resistance and transparency, this kind of plastic polyvinyl chloride, polystyrene, ABS, PMMA, polycarbonate, polyphenylene oxide, polysulfone and the like.

Different types of plastic, although having some similarities, but personality differences, be sure to do the proper selection of products or aids simulation time can produce compliant products. The temperature of the distillation column by gasoline gasoline temperature adjustment control back flow display by the rotameter. Light diesel gasoline distillation bottoms.

Injection molding machine thermoforming mold thermoplastic molding plaster molds and tin mold needs. Only the transition plaster mold is a mold, the final mold is manufactured of tin.

Because gypsum hemihydrate and water after water into gypsum (CaSOO), gypsum plaster water solubility than half a much lower solubility, gypsum constantly condense, and hemihydrate gypsum continues to dissolve, eventually all turned into gypsum, in the process of change, all the excess water to evaporate. Because the condensation was gypsum volume increased by 1%, so with plaster made of male and female mold, the inner and outer surface smooth, easy to crack tin mold.

 

The rubber injection molding machine model has the beneficia
