详细说明:

塑料依据其本身的功能来分能够分红:能够屡次反复进行熔融成型加工而基本能坚持其特性的热塑性塑料和只能进行一次熔融成型的热固性塑料两大类。依据其用途来分能够分红运用面广,价格便宜,归纳功能较好的通用塑料,如PE,PP,PVC,PS,和胺基塑料有杰出的物理力学强度,可能替代金属运用在工程机械上的工程性塑料如:ABS,尼龙, 聚酯,POM,TPX-1 等。以及在某一功能上具有特别优秀的一类工程塑料,如:具有特别好的耐辐射性,耐高温性等的特种塑料,如: 聚芳砜,液晶聚合物等。依据热塑性树脂分子结晶巨细来分,能够把热塑性塑料分红无定型聚合物和结晶型聚合物两类。 

Plastics can be divided into two categories according to their own functions: thermoplastic plastic and thermosetting plastics, which can basically adhere to its characteristics, and can only be fused once again and again. The versatile plastics, such as PE, PP, PVC, PS, and amido plastics, have outstanding physical and mechanical strength, which can be divided into a wide range of uses, such as PE, PP, PVC, PS, and amine based plastics, and may replace the engineering plastics used in engineering machinery such as ABS, nylon, polyester, POM, TPX-1, etc. And a special kind of engineering plastics, such as special plastics with special good radiation resistance, high temperature resistance, such as polysulfone, liquid crystal polymer, etc. According to the size of the thermoplastic resin, the thermoplastic polymers can be divided into two types: amorphous polymers and crystalline polymers.
