氫氧化鉀別名苛性鉀、苛性堿和鉀灰等，化學(xué)式為KOH。從它的別稱可以知道氫氧化鉀具有的特性：強(qiáng)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(fā)生潮解，并且還會(huì)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(shí)是利用它的強(qiáng)堿性去疏松，乳化和分散金屬設(shè)備內(nèi)的沉積物，從而達(dá)到對(duì)設(shè)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(zhì)。

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(yīng)，以下是純堿水解的化學(xué)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(jí)水解：Na2CO3+H2O=NaHCO3+NaOH

Primary hydrolysis: Na2CO3+H2O=NaHCO3+NaOH

二級(jí)水解：NaHCO3+H2O=H2CO3+NaOH

Secondary hydrolysis: NaHCO3+H2O=H2CO3+NaOH

因?yàn)闅溲趸浀乃夥磻?yīng)，所以所以氫氧化鉀常用于以下幾個(gè)方面：

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

（1）除去系統(tǒng)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(shè)備內(nèi)殘留的酸，從而減少金屬設(shè)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(shí)就是簡(jiǎn)單的化學(xué)原理，因?yàn)橛臀凼且环N脂類物質(zhì)，從它的化學(xué)組成成分上分析，他們是脂肪酸和甘油酯。這些物質(zhì)在遇到堿、酸、酶后會(huì)發(fā)生水解反應(yīng)，水解后則會(huì)生成甘油和脂肪酸，而這些甘油和脂肪酸就會(huì)被水溶解，沖洗掉，這就人們說(shuō)的除油污了。更多相關(guān)產(chǎn)品的內(nèi)容就來(lái)我們網(wǎng)站http://m.jsyjs.net進(jìn)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.
