PVC plastic sheet production line is a production line equipment that uses plastic as the main raw material to produce plastic sheet. The product has the characteristics of light weight, corrosion resistance, beautiful appearance, non-toxic, tasteless, non-corrosive and anti-aging.
PVC is thermally degraded in air, and the commonly used melt index cannot be used to characterize the molecular weight of polymers. In practice, it is expressed by the relative viscosity K value, which is measured by the ratio of the viscosity of the diluted polymer solution to the pure solution.
In the existing glass fiber product production line, glass fiber cloth is first cut to a fixed length, then heated in an oven, and then manually sent to a setting machine for setting. After setting, it is placed on a cooling bracket to cool and cut the edges Finished product.
Polyethylene terephthalate, also known as PET, is a crystalline saturated polyester. It is a milky white or light yellow, highly crystalline polymer with a smooth and shiny surface. Is a common resin in life, can be divided into APET, RPET and PETG.
Dear Valued Clients and Partners,Chinese New Year is coming soon, we wish you peace and love in the new year. In modern times, the Chinese New Year is scheduled to be on the first day of the first lunar month.
The Chinese name of PC sheet is polycarbonate, and the Chinese name of PET sheet is polyethylene terephthalate. Looking at the name, we can see that the two materials are not the same. Although they are both plastic, the essential differences are still very large.
Polyester polyester is formed by the polycondensation of terephthalic acid and ethylene glycol, following the general law of linear polycondensation. For the production of polyester polyester, there have been developed two kinds of synthetic technologies: direct esterification and transesterification.
Different types of plastic sheets are produced in the plastic sheet production line. These sheets are used for various reasons like the packaging. The price of each sheet is different, and it depends on the dimension and type of plastic.
PP is a thermoplastic resin. Like PE, it can be processed by all processing methods of thermoplastics. Extrusion, injection molding, blow molding, lamination, casting, biaxial stretching, powder spraying, foam molding, etc. can be used.
Pultrusion is a continuous production of glass fiber reinforced plastic profiles method, the basic process is: the traction device traction, the fiber material impregnated with resin, pre-forming, molding, cut into desired length of output profiles.
