注塑工艺对透明聚丙烯制品雾度的影响

通过实验研究了不同注塑工艺对用成核剂增透改性的透明聚丙烯制品雾度的影响，结果表明合适的熔融温度、较低的模温、较慢的注射速度、较长的保压时间和较大的保压压力有利于得到透明度较好的制品。找到原料最佳的注塑条件，有利于最大限度地发挥出原料的透明度潜能，得到理想的透明聚丙烯制品。这对塑料制品企业有积极的意义。

Influence of Injection Molding Conditions on Haze of Transparent Polypropylene Products

Study on the influence of different injection molding conditions to transparent poly- propylene with nucleating agents. The results showed： suitable melt temperature, lower mold temperature, lower injection speed, longer hold time and higher hold pressure were good for getting better products with better transparency. Find out the best injection molding conditions is good for finding out the best transparency of the raw material and getting the best transparent polypropylene goods. It is active and significant for the groups producing plastics goods.
