| 塑料光亮剂现状 Present situation of plastic brighteners 现在市场上称作塑料光亮剂的产品可分为4类。 Products that are now called plastic brighteners in the market can be divided into 4 categories. 1、聚乙烯蜡一特征：低分子蜡与乙烯的聚合物，熔点101度。在塑料上的主要用途，作为润滑剂使用，能提高熔体的流动性，但过多会层析，使产品不合格，特别是电线。 1, polyethylene wax one characteristic: low molecular weight wax and ethylene polymer, melting point 101 degrees. The main uses in plastics, as lubricants, can improve the fluidity of melts. However, too much chromatography can make products unqualified, especially wires. 2、高熔点蜡一特征：低分子合成蜡，熔点在110度左右，在塑料上的主要用途，作为外润滑剂使用。 2, high melting point wax one feature: low molecular synthetic wax, melting point of about 110 degrees, the main purpose of plastics, as external lubricants. 3、高分子物质与蜡的接枝共聚物一特征：分子量比较高，熔点可达到210度。在塑料上的主要用途是在塑料制品表面成膜，以提高塑料制品表面的光亮度及平滑度。 3, polymer material and wax graft copolymer characteristics: high molecular weight, melting point can reach 210 degrees. The main purpose of plastics is to form films on the surface of plastic products to enhance the brightness and smoothness of the surface of plastic products. 4、进口的塑料光亮剂(目前真正是进口的，只有颗粒状)一特征：分子量比较高(约17000左右)，熔点可达160度。在塑料上的主要用途是在塑料制品表面成膜，以提高塑料制品表面的光亮度及平滑度。 4, imported plastic brighteners (currently imported, only granular) one feature: the molecular weight is relatively high (about 17000), melting point can reach 160 degrees. The main purpose of plastics is to form films on the surface of plastic products to enhance the brightness and smoothness of the surface of plastic products. |
