Plastic profiles for its excellent thermal insulation properties of building materials is listed as one of China's key development. In plastic profile production process, what issues need attention in order to ensure the quality and craftsmanship profiles. Now we come to understand the plastic profile additives have? Additives a plastic profiles: impact modifiers, such as the production of plastic profiles without impact modifier manufacturers of PVC plastic profiles, plastic profiles will be very brittle, a little collision, easily broken. Plastic profile production agents commonly used impact modifiers mainly consists of the following three categories: chlorinated polyethylene, polyacrylate, ethylene - vinyl acetate copolymer. Plastics Additives two profiles: heat stabilizers for plastic profile is heat-sensitive plastic, so plastic profile production and processing of rigid PVC plastic profiles, heat stabilizers is essential. Thermal stabilizers of the metal salt decomposition of PVC absorbable HCL, thus delaying the rate of decomposition of the plastic and extend decomposition time PVC plastic profiles, plastic profiles most commonly used for the production of a composite lead salt, high efficiency thermal stability, price inexpensive. 1. Soft polyvinyl chloride containing a plasticizer is generally 30-50%. Because of soft, high strength; has good air tightness and impermeability. 2. Rigid PVC is only a small amount of a plasticizer. Its characteristics are hard, high mechanical strength, good chemical resistance. . 3. PVC poor heat resistance, strength influenced by temperature, -20 ℃ 20 ℃, when the intensity ratio dropped to 80%. Therefore, the film is not easy to keep products at low temperature; soft products temperature does not exceed 45 ℃, hard products does not exceed 60 ℃, the light will be long-term aging embrittlement. 4. PVC film in the processing, in order to prevent thermal decomposition, heat stabilizers must be added to PVC plastic profile products, due to the heat stabilizers containing lead salt, so that toxic PVC, it can not be used for food packaging. 5. PVC pest control agent in contact with the organic solvent and naphthalene, etc., will produce sticky, melting phenomenon, and easy to absorb odors; more volatile due to the plasticizer, it should not be stored for too long.
