光学塑料的稳定性大多数不及光学玻璃。一般说来，耐有机溶剂性能差，易于在机溶剂中溶解、溶胀；因些，采用超声波清洗设备技术清洗塑料零件时，对工艺条件、清洗刑都有严格要求：总的来说，要求超声波清洗设备作用力不能过激烈，清洗剂的化学作用不能太强。

Most optical plastics are less stable than optical glass. Generally speaking, it has poor resistance to organic solvents and is easy to dissolve and swell in organic solvents; Therefore, when using ultrasonic cleaning equipment technology to clean plastic parts, there are strict requirements for process conditions and cleaning penalty: Generally speaking, the force of ultrasonic cleaning equipment should not be too intense, and the chemical effect of cleaning agent should not be too strong.

对清洗剂来说，要求能够润湿零件及污物，这样，清洗剂在超声埸中对污物便可起溶解、乳化、分散作用；同时还要求清洗液易于在零件表面形成—·层液膜，以防止污物的再吸附，沉积，砂：以清洗剂可考虑采用F113、非离子型表面活性剂溶液、酶制剂溶液：

For the cleaning agent, it is first required to be able to wet the parts and dirt, so that the cleaning agent can dissolve, emulsify and disperse the dirt in the ultrasonic field; At the same time, it is also required that the cleaning solution is easy to form a layer of liquid film on the surface of the parts, so as to prevent the re adsorption and deposition of the dirt

酶制剂溶液指脂肪酶或蛋白酶的水溶液。脂肪酶在适当温度、pH值和超声波清洗设备作用千·能促使油脂迅速水解，生成溶于水的有机酸及醇；蛋白酶能促使蛋白质迅速水解，生成各种氨基酸而溶于水。

Enzyme preparation solution refers to the aqueous solution of lipase or protease. Lipase can make oil hydrolyze rapidly and produce water-soluble organic acids and alcohols under proper temperature, pH value and ultrasonic cleaning equipment; Protease can promote the rapid hydrolysis of protein to produce various amino acids and dissolve in water.

因此，这种既能迅速去除油污而又不影响光学零件表面性能的酶制剂，是目前塑料光学零件在超声波清洗设备清洗工艺中较为理想的清洗剂。

Therefore, the enzyme preparation, which can quickly remove oil stains without affecting the surface properties of optical parts, is an ideal cleaning agent for plastic optical parts in the cleaning process of ultrasonic cleaning equipment.
