The structure of an improved pin gate,called twin-gate,was described,and the rheological behavior of polymer melt passing through the gate was studied. At the same length,sectional area and throughput as the conventional pin gate, the melt temperature is higher, the viscosity lower and the pressure drop bigger when the twin-gate was used.

介绍了一种改进的点浇口———孪浇口的结构 ,讨论了聚合物熔体流经该浇口时的流变性能 ,在浇口的长度、总截面积以及流量一致的条件下 ,与常用点浇口相比 ,孪浇口使熔体温度升高和使熔体粘度降低的程度要大 ,但压力降增加的幅度也大。并以聚丙烯 (PP)为原料 ,对比分析了PP熔体流经常用点浇口和孪浇口时的剪切速率、压力降、温度和粘度的变化。当PP熔体温度为 2 40℃时 ,熔体流经孪浇口和点浇口后 ,温度的增加值分别为 2 5 1℃和11 3℃。与常用点浇口相比 ,孪浇口处熔体的剪切速率提高约 0 41倍 ,粘度下降约 0 3倍 ,但压力降却增加了 2 2 3倍
