| 以下所建议的是典型的加工条件，具体情况要取决于机器的设计（包括螺杆和机头）、筛网的目数、电缆的尺寸等因素。挤出机螺杆直径 ： φ150 mmL/D： 24筛网目数： 40/80/150/350/150/80/40 （取决于电压等级）温度设定（摄氏度）：C1 C2 C3 C4 C5 C6 连接 机头 螺杆冷却*100 120 120 115 115 115 120 120 70* 部分冷却（仅限加料段）+ 如果不具备螺杆冷却，则建议将C1的温度设定在70摄氏度。+ 如果螺杆全段均有螺杆冷却，则建议将螺杆冷却温度设定在100摄氏度，将C1的设定在70摄氏度。所建议的熔融温度在120至130摄氏度之间。如果超过了130摄氏度，则建议降低C2至C6的设定温度。开车设定值与正常的操作条件相比，开车时的温度设定值建议要高出5到10摄氏度。储存储存环境或是条件会对所允许的储存时间产生极大的影响。 储存应该符合电缆制造商的制造管理规范的要求。所建议的储存温度为15-30°C, 而且应该建立产品使用上先入先出的控制规范。极端条件下的储存可能会影响到产品的品质、加工或是性能。即使在高温下，NUCV-9253S XL K也可保持储存的稳定性。在温度低于15°C的时候有可能开始发生过氧化物的迁移。一般来说，如果储存温度正确地保持在15至30°C 的话，则自其生产日期开始，该材料的保质期为两年时间。包装NUCV-9253S XL K 的交货包装有500kg 的UNICLEANTM 大袋或是500kg的底部卸货八角箱。 |
