光學塑料的穩定性大多數不及光學玻璃。一般說來，耐有機溶劑性能差，易于在機溶劑中溶解、溶脹；因些，采用超聲波清洗設備技術清洗塑料零件時，對工藝條件、清洗刑都有嚴格要求：總的來說，要求超聲波清洗設備作用力不能過激烈，清洗劑的化學作用不能太強。

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.

對清洗劑來說，首先要求能夠潤濕零件及污物，這樣，清洗劑在超聲埸中對污物便可起溶解、乳化、分散作用；同時還要求清洗液易于在零件表面形成—·層液膜，以防止污物的再吸附，沉積，砂：以清洗劑可考慮采用貴113、非離子型表面活性劑溶液、酶制劑溶液：

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

酶制劑溶液指脂肪酶或蛋白酶的水溶液。脂肪酶在適當溫度、辮貶值和超聲波清洗設備作用千·能促使油脂迅速水解，生成溶于水的有機酸及醇；蛋白酶能促使蛋白質迅速水解，生成各種氨基酸而溶于水。

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，這種既能迅速去除油污而又不影響光學零件表面性能的酶制劑，是目前塑料光學零件在超聲波清洗設備清洗工藝中較為理想的清洗劑。

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.
