超聲波清洗機清洗所用機清洗劑的分類方法也很多，我們通常分成非水系、水系、半水系超聲波清洗機清洗劑三大類。
There are also many classification methods of machine cleaning agents used for ultrasonic cleaning machine cleaning. We usually divide them into three categories: non water system, water system and semi water system ultrasonic cleaning agents.
1、非水系
1. Non drainage system
非水系超聲波清洗機清洗劑是指不溶于水的有機溶劑。
Non aqueous ultrasonic cleaner cleaning agent refers to organic solvent insoluble in water.
精密工業超聲波清洗機清洗使用的非水系超聲波清洗機清洗劑主要是烴類(石油類)、 氯代烴，氟代烴、溴代烴、醇類、有機硅油、萜烯等有機溶劑。
The non-aqueous ultrasonic cleaning agents used for cleaning precision industrial ultrasonic cleaning machines are mainly hydrocarbon (petroleum), chlorinated hydrocarbon, fluorohydrocarbon, brominated hydrocarbon, alcohol, organic silicone oil, terpene and other organic solvents.
衡量溶劑的主要指標有KB值 (貝殼松脂丁醇值)，AP(苯胺點)、 SP溶解參數)、表面張力、密度、粘度，沸點、閃點、暴露濃度等參數。
The main indicators for measuring solvents include KB value (shellpine butanol value), AP (aniline point), SP dissolution parameter), surface tension, density, viscosity, boiling point, flash point, exposure concentration and other parameters.
KB值很高，也就是溶解力很強的溶劑，不一定是好的超聲波清洗機清洗劑。一個好的精密工業超聲波清洗機清洗劑必須具備以下條件：
A solvent with a high KB value, that is, a solvent with strong solubility, may not be a good ultrasonic cleaner. A good cleaning agent for precision industrial ultrasonic cleaning machine must meet the following conditions:
①化學性能穩定、不易與被超聲波清洗機清洗物發生反應；
① The chemical property is stable, and it is not easy to react with the cleaning materials of the ultrasonic cleaning machine;
②表面張力和粘度小、滲透力強；
② Small surface tension and viscosity, strong permeability;
③沸點低，可以自行干燥；

③ Low boiling point, self drying;
④沒有閃點、不易燃；
④ No flash point, nonflammable;
⑤KB值不應太高，避免與被超聲波清洗機清洗物相溶；
⑤ The KB value should not be too high to avoid being miscible with the substance cleaned by the ultrasonic cleaner;
⑥低毒性、使用安全：
⑥ Low toxicity and safe use:
⑦非ODS和低GWP值(全球變暖潛能值)、環保。
⑦ Non ODS and low GWP (global warming potential), environmental protection.
2、水系
2. Drainage system
水是重要的超聲波清洗機清洗劑，有著其它任何超聲波清洗機清洗劑無法替代的作用和地位。水有很強的溶解力和分散力，但是水的表面張力大。在使用中需要添加表面活性劑，以減小表面張力，增加表面濕潤性。
Water is the most important cleaning agent for ultrasonic cleaning machine, and it has a role and position that can not be replaced by any other cleaning agent for ultrasonic cleaning machine. Water has strong solubility and dispersion, but its surface tension is large. Surfactant shall be added in use to reduce surface tension and increase surface wettability.
在一般工業超聲波清洗機清洗中，酸，堿和水的配合比較常見，有些金屬用水洗要加入防銹劑；在精密和超精密工業超聲波清洗機清洗中，大部分要求將水制成純凈水。通常以電阻率來衡量水純度。
In the general industrial ultrasonic cleaning machine, the coordination of acid, alkali and water is common, and some metals need to add rust inhibitor when washed with water; In the cleaning of precision and ultra precision industrial ultrasonic cleaning machines, most of the water is required to be made into pure water. Water purity is usually measured by resistivity.
3、半水系
3. Semidrainage system
半水系超聲波清洗機清洗劑也叫準水系超聲波清洗機清洗劑，是由高沸點溶劑及活性劑等組成，如醇類、乙二醇酯、有機烴類、N—甲基吡咯烷酮等。通常含有5％一20％的水分，一般不易燃燒。但加溫超聲波清洗機清洗時，水含量控制不當，可能產生燃燒現象。
Semi aqueous ultrasonic cleaner cleaner is also called quasi aqueous ultrasonic cleaner cleaner, which is composed of high boiling point solvents and active agents, such as alcohols, ethylene glycol esters, organic hydrocarbons, N-methylpyrrolidone, etc. It usually contains 5% - 20% moisture and is not easy to burn. However, improper control of water content may lead to combustion during heating ultrasonic cleaning.
半水系超聲波清洗機清洗與溶劑洗有一些不同。它的超聲波清洗機清洗原理是剝離去除，而不是溶解。為了防止已經剝落的油污再附到被超聲波清洗機清洗物上，超聲波清洗機清洗液要連續地循環，并增加油水分離器。
There are some differences between semi water ultrasonic cleaning machine and solvent cleaning. Its ultrasonic cleaning principle is stripping removal, not dissolution. In order to prevent the stripped oil from attaching to the cleaning materials of the ultrasonic cleaner, the cleaning solution of the ultrasonic cleaner shall be continuously circulated, and an oil-water separator shall be added.
半水洗通常超聲波清洗機清洗效果很好， 但運行成本較高。廢液不能再生回收，重復使用，含COD(化學耗氧量) 較高，需要進行廢水處理。
Semi water washing usually has a good cleaning effect, but the operating cost is high. The waste liquid cannot be recycled and reused, with high COD (chemical oxygen demand), so it needs to be treated.
