在生产中选择润滑剂时，应使之达到以下要求：

When the lubricant is selected in production, it should be made to meet the following requirements:

1.润滑效能高而持久；

1. the lubrication efficiency is high and lasting.

2.与树脂的相容性大小适中，内部、外部润滑作用的平衡；不喷霜、不易结垢；

2. the compatibility of the resin is moderate, the internal and external lubrication of the balance, no spray frost, not easy to scale;

3.表面引力小，粘度小，在界面处的扩展性好，易形成界面层；

The 3. surface has small gravitational force, small viscosity and good expansibility at the interface, and it is easy to form the interface layer.

4.尽量不降低聚合物的各种优良性能，不影响塑料的二次加工性能；

4. not to reduce the excellent properties of the polymer, and do not affect the two processing properties of the plastic.

5.本身的耐热性和化学稳定性优良，在加工中不分解、不挥发；

5. itself has good heat resistance and chemical stability, and it does not decompose and volatilize in processing.

6.不腐蚀设备，不污染薄膜，没有毒性。

6. does not corrode the equipment, does not pollute the film, and has no toxicity.
