氫氧化鉀用途非常廣泛，它應用在不同的行業(yè)，不管應用在哪一行業(yè)它的作用都非常大，今天我們就來講解一下固體氫氧化鉀可做除油劑。

Potassium hydroxide has a wide range of uses. It is used in different industries. No matter which industry it is used in, it plays a very important role. Today we will explain that solid potassium hydroxide can be used as an oil remover.

固體氫氧化鉀是常用的除油劑之一，其與動植物油中的硬脂酸產(chǎn)生皂化反應，生成水溶性的硬脂酸鈉（肥皂）和丙三醇（甘油）。當氫氧化鉀濃度太低，pH∠10.5時，硬脂酸鈉發(fā)生水解，除油效果降低；濃度太高，會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 oil removers. It saponifies with stearic acid in animal and vegetable oils to produce water-soluble sodium stearate (soap) and glycerol (glycerin). When the concentration of potassium hydroxide is too low, pH ∠ 10.5, sodium stearate will hydrolyze and the oil removal effect will be reduced; If the concentration is too high, the solubility of sodium stearate and surfactant will be reduced, making the water washability worse, and it is not easy to clean after degreasing. 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（鋁及鋁合金除油時間應嚴格控制在1分鐘之內，以免遭受腐蝕）。

The degreasing solution made of solid potassium hydroxide is applicable to the 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).

固體氫氧化鉀是強腐蝕劑，使用時要穿戴好防護用品，注意，含有氫氧化鉀的除油廢水應經(jīng)過中和處理后才能排放。

Solid potassium hydroxide is a strong corrosive agent. Wear protective equipment and pay attention to safety when using it. The degreasing wastewater containing potassium hydroxide can only be discharged after neutralization treatment.

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

In addition, potassium hydroxide is suitable for all kinds of reactive dyes. It has high color giving capacity 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. In the production of package yarn, the difference between inner and outer layers can be effectively solved.

氫氧化鉀是白色粉末或片狀固體，具強堿性及腐蝕性，溶于水、乙醇，微溶于乙醚，易吸收空氣中水分而潮解，吸收二氧化碳而成碳酸鉀，當溶解于水、醇或用酸處理時產(chǎn)生大量熱量。

Potassium hydroxide is a white powder or flake solid with strong alkalinity and corrosivity. It is soluble in water, ethanol, and slightly soluble in ether. It is easy to absorb moisture in the air and deliquescence. It absorbs carbon dioxide to form potassium carbonate. When it is dissolved in water, alcohol, or treated with acid, it generates a lot of heat.

氫氧化鉀暴露于空氣中時，易吸收二氧化碳和水分，逐漸變成碳酸鉀。易溶于水，溶解時放出大量溶解熱，有強的吸水性，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。有強的堿性和腐蝕性，其性質與燒堿相似。能引起灼傷，易于吸收空氣中的水分和CO2。

When potassium hydroxide is exposed to the air, it is easy to absorb carbon dioxide and water, and gradually becomes potassium carbonate. It is easily soluble in water. When dissolved, it emits a large amount of heat of dissolution, and has strong water absorption. It can absorb water in the air to dissolve, and absorb carbon dioxide to gradually become potassium carbonate. Soluble in ethanol, slightly soluble in ether. It is strongly alkaline and corrosive, and its properties are similar to caustic soda. It can cause burns and easily absorb moisture and CO2 in the air.
