The results showed an optimum throat should be located near the die and peroxide could be fed in by means of weight batcher of high pressure metering pump system,which could control the production by means of pressure gauge and the decrease of peroxide.

• 结果表明 ,过氧化物最佳注入口应选择在靠近口模处 ,加入方式可选择侧位重量加料器或高压计量泵系统 ,后者可通过压力表、过氧化物的递减量对生产过程进行控制。
