Huike new molecular sieve composite stabilizer uses the lead salt+calcium zinc+modified molecular sieve+antioxidant stabilization system in terms of stability.In the early stage of production and processing,lead tribasic lead sulfate and dibasic lead phosphite are used as the main stabilizing components to ensure mixing Normal processing of granulation.In the extrusion process,hard lead,hard calcium,modified molecular sieve and other different metals are used as the main stable components to ensure the smooth operation of the process,ensure the cleaning cycle and normal processing.In the process of extrusion molding,normal placement and transportation at the later stage of production and processing, antioxidant is used as the main stabilizing component to ensure the color stability and weather resistance at the later stage of extrusion molding.The stabilization mechanisms of different raw materials before,during and after use complement each other,making them have better synergy.
