超声波清洗设备清洗机所用的清洗剂多为液体洗涤剂，组成模式为：表面活性剂、赘合剂、其他助剂，还有其它有机溶剂如三氯乙烯。

启航彩Most of the cleaning agents used in the cleaning machine of ultrasonic cleaning equipment are liquid detergents, which are composed of surfactants, additives and other organic solvents such as trichloroethylene.

启航彩某物质当其溶于水即使浓度很小时，能显着降低水同空气的表面张力，或水同其他物质的界面张力，则该物质称为表面活性剂。水溶性表面活性剂的分子结构都具有不对称的、极性的特点。

启航彩When a substance is dissolved in water, even if its concentration is very small, it can significantly reduce the surface tension between water and air, or the interfacial tension between water and other substances. The molecular structures of water-soluble surfactants are asymmetric and polar.

启航彩向吸附在水溶液同其他相的界面上，这样大大改变了体系的物理性质，特别是各相界面的界面张力。

启航彩In this way, the physical properties of the system, especially the interfacial tension of each phase, are greatly changed.

根据表面活性剂溶于水时亲水基团所表现出来的电性，可把表面活性剂分为阴离子、阳离子、中性及两性表面活性剂。

启航彩Surfactants can be divided into anionic, cationic, neutral and amphoteric surfactants according to the electric properties of hydrophilic groups when they are dissolved in water.

螯合剂和溶液中的某些金属离子如Ca2+、Mg2+等形成稳定的螯合体，从而使洗涤剂具有抗硬水性的功能，具体到镜片清洗时，又可和镜片表面的某些含Ca2+、Mg2+的物质化合而达到清洗作用。

启航彩Chelating agent and some metal ions in the solution such as Ca2 +, Mg2 + form stable chelating body, so that the detergent has the function of resisting hard water. When cleaning the lens, it can combine with some substances containing Ca2 +, Mg2 + on the surface of the lens to achieve the cleaning effect.

启航彩某些助剂的加入，再起到以下作用：

With the addition of some additives, the following effects can be achieved:

缓冲作用：使洗涤剂的PH值能维持稳定。

Buffering effect: keep the pH value of detergent stable.

对金属的抗腐蚀作用。

Corrosion resistance to metals.

启航彩能增加洗涤剂的乳化能力和乳化稳定性。

启航彩It can increase the emulsifying capacity and emulsifying stability of detergent.
