光學（xué）塑料的穩定性大多數不及光學（xué）玻璃。一（yī）般說來，耐有機（jī）溶劑性能（néng）差，易於在機溶劑中溶解、溶脹；因些，采用超聲波清洗設備技術清洗塑料零件時（shí），對（duì）工藝條（tiáo）件、清洗刑（xíng）都有嚴格要求：總的來（lái）說，要求超（chāo）聲波清洗設備作（zuò）用力不能過激烈，清洗劑（jì）的化學作（zuò）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（néng）夠潤濕零件及汙物，這樣，清洗劑在（zài）超聲埸中對汙物便可起溶解、乳化、分散作用；同時還要求清洗液易於在（zài）零件表麵（miàn）形成—·層液膜，以防止汙（wū）物的再吸附（fù），沉積，砂：以（yǐ）清洗劑可考慮采用F113、非離子型表麵活性劑溶液、酶製劑（jì）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

酶製劑溶液指脂肪酶或蛋白酶的水溶液。脂肪酶在適當溫度（dù）、pH值和超聲波（bō）清洗設備作用千·能（néng）促使油脂迅速水解，生成溶於水的有機酸及醇；蛋白酶能促（cù）使蛋白質迅速（sù）水解，生成各（gè）種（zhǒng）氨基酸而溶於水。

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（qù）除油汙（wū）而又不影響光學零件表（biǎo）麵性能（néng）的酶製劑，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.
