| 加工技巧 HFDK-0587 BK A 在各种条件下提供出色的表面光洁度和卓越的处理性能。为实现最佳效果，建议使用 120 到 140°C 的熔体温度范围。在学习加工 DOW ENDURANCE HFDK-0587 BK 时，建议将下面的挤塑机桶和模具设置作为起点。具体的机器设置将取决于挤塑机和模具设计，并且必须通过传统实践方式来建立。一般建议采用 20/80 网筛组。 对于 Maillefer 挤塑机，建议使用双跨测量螺栓，具有 20-22/1, L/D 和 2.0-2.5 的压缩比，以 5-20 rpm 的速度运转。 对于 Troester 挤塑机，如果不使用螺栓冷却，或在大约 105 °C 相对高的设置下使用，则 Z1 和 Z2 应在比下面指示温度更低的温度下运转。 建议的干燥条件为 70 °C 下 4 个小时。 |
