Choose the right cleaning agent

Whether the use of commercial cleaning agents, according to different manufacturers and production conditions; plastic processing enterprises can also be based on their own production, the use of different resins to do screw cleaning materials, the unit can save a small amount of expenditure.

Choose the correct cleaning method

清洗螺杆的第一步是关掉加料插板,也就是关闭料斗底部的下料口;然后降低螺

杆转速至

15-25r/min,

并将这一速度保持到模头前端的熔体流停止流动为止。

机筒的

所有加热区的温度都应设置在

200°

C

。一旦机筒达到这一温度,立即开始清洁。根

据挤出工艺不同(可能需要拆下模头以减少挤出机前端压力过高的危险),故在清

洗时必须由一个人来完成:操作者从控制面板观察螺杆转速和扭矩,同时观察挤出

压力以确保系统压力不会过高。在整个过程中,螺杆转速应保持在

20r/min 

之内。

在低压模头的应用中,首先不要拆下模头进行清洗。在挤出物从加工树脂完全转换

成清洁树脂时立即停机并拆下模头,然后进行重新启动螺杆(转速在

10r/min 

之间

内),以便使残留的清洁树脂流出。

The first step in cleaning the screw is to turn off the feed plate, that is, to close the lower feed port of the hopper; then reduce the screw speed to 15-25r / min and keep this speed at the front of the die The melt flow stops flowing. The temperature of all heating zones of the barrel should be set at 200 ° C. Once the barrel reaches this temperature, it begins to clean immediately. Depending on the extrusion process (it may be necessary to remove the die to reduce the risk of high pressure at the front end of the extruder), it must be done by cleaning the operator: the operator sees the screw speed and torque from the control panel while observing the squeeze Out of pressure to ensure that the system pressure is not too high. Throughout the process, the screw speed should be kept within 20r / min. In low-voltage die applications, first do not remove the die for cleaning. Immediately after the extrudate is completely converted from the processing resin to the cleaning resin, the die is removed and the die is removed and the screw is restarted

10 r / min) so that the residual cleaning resin flows out.
