氫氧化鉀別名苛性鉀、苛性堿和鉀灰等，化學式為KOH。從它的別稱可以知道氫氧化鉀具有的特性：強堿性和腐蝕性。氫氧化鉀易溶于水，并且放出大量的熱，非常容易吸收空氣中的水分而發生潮解，并且還會吸收空氣中的二氧化碳變成碳酸鉀。

Potassium hydroxide is also known as caustic potash, caustic soda and potassium ash, and its chemical formula is KOH. From its nickname, we can know the characteristics of potassium hydroxide: strong alkalinity and corrosivity. Potassium hydroxide is easily soluble in water and emits a lot of heat. It is very easy to absorb moisture in the air and cause deliquescence. It also absorbs carbon dioxide in the air and turns it into potassium carbonate.

氫氧化鉀清洗其實是利用它的強堿性去疏松，乳化和分散金屬設備內的沉積物，從而達到對設備污垢清洗的目的，但是堿清洗不能除去一般水垢和金屬腐蝕物質。

In fact, potassium hydroxide cleaning is to use its strong alkalinity to remove looseness, emulsify and disperse deposits in metal equipment, so as to achieve the purpose of cleaning equipment dirt. However, alkali cleaning cannot remove general scale and metal corrosion substances.

氫氧化鉀除油污就是堿與水的反應，以下是純堿水解的化學式：

Removal of oil contamination by potassium hydroxide is the reaction of alkali and water. The following is the chemical formula of soda ash hydrolysis:

一級水解：Na2CO3+H2O=NaHCO3+NaOH

Primary hydrolysis: Na2CO3+H2O=NaHCO3+NaOH

二級水解：NaHCO3+H2O=H2CO3+NaOH

Secondary hydrolysis: NaHCO3+H2O=H2CO3+NaOH

因為氫氧化鉀的水解反應，所以所以氫氧化鉀常用于以下幾個方面：

Because of the hydrolysis reaction of potassium hydroxide, potassium hydroxide is commonly used in the following aspects:

（1）除去系統或表面的油污；

(1) Remove the oil stain on the system or surface;

（2）與酸交替使用，除去硫酸鈣及矽酸鈣等酸清洗難于去除的污垢；

(2) It can be used alternately with acid to remove dirt that is difficult to remove by acid cleaning, such as calcium sulfate and calcium silicate;

（3）酸洗之后用堿洗，用于中和水及設備內殘留的酸，從而減少金屬設備的腐蝕。

(3) After acid cleaning, alkali cleaning is used to neutralize water and residual acid in equipment, so as to reduce corrosion of metal equipment.

其中氫氧化鉀除油污原理其實就是簡單的化學原理，因為油污是一種脂類物質，從它的化學組成成分上分析，他們是脂肪酸和甘油酯。這些物質在遇到堿、酸、酶后會發生水解反應，水解后則會生成甘油和脂肪酸，而這些甘油和脂肪酸就會被水溶解，沖洗掉，這就人們說的除油污了。更多相關產品的內容就來我們網站http://www.shrisa.cn進行咨詢吧！

Among them, the principle of removing oil stain by potassium hydroxide is actually a simple chemical principle, because oil stain is a kind of lipid substance. According to its chemical composition, they are high-class fatty acids and glycerides. These substances will undergo hydrolysis reaction after encountering alkali, acid and enzyme. After hydrolysis, they will generate glycerol and higher fatty acids, which will be dissolved by water and washed away, which is called degreasing.
