Potassium hydroxide is widely used in different industries. It plays a very important role in any industry. Today we will explain that solid potassium hydroxide can be used as degreaser.

　　固體氫氧化鉀是常用的除油劑之一，其與動(dòng)植物油中的硬脂酸產(chǎn)生皂化反應(yīng)，生成水溶性的硬脂酸鈉（肥皂）和丙三醇（甘油）。當(dāng)氫氧化鉀濃度太低，pH∠10.5時(shí)，硬脂酸鈉發(fā)生水解，除油效果降低；濃度太高，會(huì)使硬脂酸鈉和表面活性劑的溶解度降低，使水洗性變差，除油后不易洗凈。故固體氫氧化鉀的用量一般不超過100g/L，通常都在50g/L~70g/L之間。

　　Solid potassium hydroxide is one of the commonly used deoilers. It reacts with stearic acid in animal and vegetable oils to produce water-soluble sodium stearate (soap) and glycerol (glycerol). When the concentration of potassium hydroxide is too low and the pH is 10.5, sodium stearate hydrolyzes and the oil removal effect decreases; if the concentration is too high, the solubility of sodium stearate and surfactant will be reduced, and the washability will be worse, and it will not be easy to clean after oil removal. Therefore, the amount of solid potassium hydroxide generally does not exceed 100g/L, usually between 50g/L and 70g/L.

　　使用固體氫氧化鉀制造的除油液適用于鋼鐵、銅及銅合金、鋁及鋁合金的除油（鋁及鋁合金除油時(shí)間應(yīng)嚴(yán)格控制在1分鐘之內(nèi)，以免遭受腐蝕）。固體氫氧化鉀是強(qiáng)腐蝕劑，使用時(shí)要穿戴好防護(hù)用品，注意，含有氫氧化鉀的除油廢水應(yīng)經(jīng)過中和處理后才能排放。

　　The degreasing liquid made of solid potassium hydroxide is suitable for degreasing of steel, copper and copper alloys, aluminum and aluminum alloys (the degreasing time of aluminum and aluminum alloys should be strictly controlled within 1 minute to avoid corrosion). Solid potassium hydroxide is a strong corrosive agent. Protective articles should be worn well and safety should be paid attention to when using. Oil removal wastewater containing potassium hydroxide should be neutralized before discharging.

　　另外氫氧化鉀適用于各種活性染料，對(duì)各種結(jié)構(gòu)的活性染料都有較高的給色量和重現(xiàn)性；適用于各種設(shè)備，尤其在低浴比和氣霧染色機(jī)上顯示其獨(dú)特的優(yōu)越性。在筒子紗的生產(chǎn)上能有效解決內(nèi)外層層差。

　　In addition, potassium hydroxide is suitable for all kinds of reactive dyes. It has high color feeding and reproducibility for all kinds of reactive dyes. It is suitable for all kinds of equipment, especially in low bath ratio and aerosol dyeing machine. The difference between inner and outer layers can be effectively solved in the production of cheese yarn.

　　氫氧化鉀是白色粉末或片狀固體，具強(qiáng)堿性及腐蝕性，溶于水、乙醇，微溶于乙醚，極易吸收空氣中水分而潮解，吸收二氧化碳而成碳酸鉀，當(dāng)溶解于水、醇或用酸處理時(shí)產(chǎn)生大量熱量。但是大家對(duì)它的易潮解性有多少了解呢？下面就給大家來具體講解一下吧。

　　Potassium hydroxide is a white powder or flaky solid with strong alkalinity and corrosiveness. It is soluble in water and ethanol and slightly soluble in ether. It is easy to absorb moisture in air and deliquescence. It absorbs carbon dioxide to form potassium carbonate. When it is dissolved in water, alcohol or treated with acid, it produces a lot of heat. But how much do you know about its deliquescence? Now let's give you a detailed explanation.

　　易潮解：氫氧化鉀暴露于空氣中時(shí)，易吸收二氧化碳和水分，逐漸變成碳酸鉀。易溶于水，溶解時(shí)放出大量溶解熱，有極強(qiáng)的吸水性，在空氣中能吸收水分而溶解，并吸收二氧化碳逐漸變成碳酸鉀。溶于乙醇，微溶于醚。有極強(qiáng)的堿性和腐蝕性，其性質(zhì)與燒堿相似。能引起灼傷，易于吸收空氣中的水分和CO2。

　　Easy deliquescence: Potassium hydroxide is easy to absorb carbon dioxide and water when exposed to air, and gradually becomes potassium carbonate. It is easy to dissolve in water and releases a lot of heat of dissolution when dissolving. It has strong water absorption. It can absorb water and dissolve in air, and absorb carbon dioxide and gradually become potassium carbonate. Soluble in ethanol, slightly soluble in ether. It has strong alkalinity and corrosiveness, and its properties are similar to those of caustic soda. Can cause burns, easy to absorb moisture and CO2 in the air.

　　以上就是給大家總結(jié)的關(guān)于氫氧化鉀易潮解性的簡(jiǎn)單介紹，希望大家都有一定的學(xué)習(xí)，另外，在大家使用的時(shí)候一定注意，避免給自身帶來傷害，想了解更多資訊，請(qǐng)繼續(xù)關(guān)注我們吧。
