塑料的成分有哪些

    塑料并不是一种纯物质，而是由很多材料配制成的，下面就由塑料原料的厂家来为我们介绍一下它是由哪些成分组成的：Plastics are not pure substances, but are made up of many materials. The following is a description of which components it consists of:
        第一是合成树脂，这是塑料原料最主要的成分，因为树脂的含量大，所以树脂的性质常常决定了塑料的性质。第二是填料，又叫填充剂，它可以提高塑料的强度和耐热性能，并且降低成本。第三是增塑剂，可以增加塑料的可塑性和柔软性，降低脆性，使塑料易于加工成型。第四是稳定剂，可以防止合成树脂在加工和使用过程中受光和热的作用分解和破坏，延长使用寿命。第五是着色剂，它可以使塑料具有各种鲜艳、美观的颜色。第六是润滑剂，它的作用是防止塑料在成型时不粘在金属模具上，同时可使塑料的表面光滑美观。-First of all, synthetic resin, which is the most important component of plastic raw materials, due to high resin content, so the nature of the resin often determines that of the plastic. The second is fillers, which increase the strength and heat resistance of plastics and therefore, reduce costs. The third is plasticizer, which can increase the plasticity and softness of plastics, reduce brittleness, and make plastics easier to process and shape. Next up the stabilizer, which can prevent the synthetic resin from being decomposed and destroyed by light and heat during its processing and use, thereby prolonging its service life. The fifth is the colorant, which can make plastics have a variety of vivid colors. The sixth is the lubricant. Its role is to prevent the plastic from sticking to the metal mold during molding and at the same time make the surface of the plastic smooth and beautiful.
        其实除了以上所述的这些成分以外，塑料中还可以根据需要加入阻燃剂、发泡剂、抗静电剂等。-In addition to the above-mentioned components, a flame retardant, a foaming agent, an antistatic agent, and the like may also be added to the plastic as required.
