91视频下载大全清洗機所用的清洗劑多為液體洗滌劑，組成模式為：表麵活性劑、贅合劑、其他助劑，還有其它有機溶劑如三氯乙烯。

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.

某物質當其溶於水即使濃度很小時，能顯著降低水同空氣的表麵張力，或水同其他物質的界麵張力，則該物質稱為表麵活性劑。水溶性表麵活性劑的分子結構都具有不對稱的、極性的特點。

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.

向吸附在水溶液同其他相的界麵上，這樣大大改變了體係的物理性質，特別是各相界麵的界麵張力。

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

根據表麵活性劑溶於水時親水基團所表現出來的電性，可把表麵活性劑分為陰離子、陽離子、中性及兩性表麵活性劑。

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.

螯合劑和溶液中的某些金屬離子如Ca2+、Mg2+等形成穩定的螯合體，從而使洗滌劑具有抗硬水性的功能，具體到鏡片清洗時，又可和鏡片表麵的某些含Ca2+、Mg2+的物質化合而達到清洗作用。

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.

某些助劑的加入，再起到以下作用：

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

緩衝作用：使洗滌劑的PH值能維持穩定。

Buffering effect: keep the pH value of detergent stable.

對金屬的抗腐蝕作用。

Corrosion resistance to metals.

能增加洗滌劑的乳化能力和乳化穩定性。

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