塑料异型材是采用ＰＶＣ加十多种添加剂生产而成，其综合性能优异，是我国建材行业大力推广的新产品。但塑料异型材生产工艺复杂，尤其在混料工序上，原料品种多，粉尘大，劳动强度高等原因，易导致混料出差错。为此，各种复合稳定剂应运而生，如铅类、锡类、稀土复合稳定... Plastic profile is made of PVC plus more than 10 kinds of additives, and its comprehensive performance is excellent. It is a new product vigorously promoted by China’s building materials industry. However, the production process of plastic profiled materials is complex, especially in the mixing process, where there are many varieties of raw materials, large dust, and high labor intensity, which can easily lead to errors in blending. To this end, a variety of composite stabilizers came into being, such as lead, tin, rare earth composite stability ...
