氫氧化鉀是強堿，具有強堿性及腐蝕性，可使石蕊試液變藍、酚酞試液變紅。下面就來講講氫氧化鉀在各行業中的用途內容吧。
Potassium hydroxide is a strong base with strong alkalinity and corrosiveness, which can make litmus test solution blue and phenolphthalein test solution red. Let’s talk about the use of potassium hydroxide in various industries.
1、農業中
1. In agriculture
①.氫氧化鉀用于調節土壤pH值。
① Potassium hydroxide is used to adjust soil pH.
②.用于生產肥料，為作物提供鉀，特別是那些不能耐受氯離子的作物。
② It is used to produce fertilizers and provide potassium for crops, especially those that cannot tolerate chloride ions.
③.用于除草劑和殺菌劑，用亞磷酸和氫氧化鉀的混合物，可定期噴灑以防病蟲害，用這種方法處理的作物幾乎沒有農藥殘留。
③. It is used as herbicide and bactericide. It is a mixture of phosphorous acid and potassium hydroxide. It can be sprayed regularly to prevent pests and diseases. The crops treated by this method have almost no pesticide residues.
2、化學工業中
2. In the chemical industry
①.氫氧化鉀主要用作鉀鹽生產的原料，如高錳酸鉀、碳酸鉀、鋁酸鉀、月桂酸鹽、甲酸鹽、葡萄糖酸鹽等。
①. Potassium hydroxide is mainly used as raw material for potassium salt production, such as potassium permanganate, potassium carbonate, potassium aluminate, laurate, formate, gluconate, etc.
②.用于調節化學溶液pH值，化學分析試劑，例如在酸滴定中，幫助確定濃度水平。
②. Used to adjust the pH value of chemical solutions, chemical analysis reagents, such as in acid titration, to help determine the concentration level.
③.還用于促進干燥，可用作干燥劑，以去除堿性溶劑中的水分，尤其是胺類和吡啶類。
③. It is also used to promote drying and can be used as a desiccant to remove water in alkaline solvents, especially amines and pyridines.
3、化學實驗室
3. Chemical laboratory
氫氧化鉀測試有助于檢測皮膚上的真菌感染，還有助于研究昆蟲解剖學，因為它加速了軟組織的分解過程。
The potassium hydroxide test helps to detect fungal infections on the skin and also helps to study insect anatomy because it accelerates the decomposition process of soft tissue.

4、石化行業
4. Petrochemical Industry
①.在石油和天然氣的精煉中，氫氧化鉀有助于去除有機酸和硫化合物。
① In the refining of oil and natural gas, potassium hydroxide helps to remove organic acids and sulfur compounds.
②.在從油脂生產生物柴油時，起催化劑的作用。
② It acts as a catalyst in the production of biodiesel from fats and oils.
③.氣流中的二氧化碳、三氧化硫、三氧化氮在氫氧化鉀的幫助下被吸收。
③ Carbon dioxide, sulfur trioxide and nitrogen trioxide in the gas stream are absorbed with the help of potassium hydroxide.
5、化妝品行業
5. Cosmetics industry
①.氫氧化鉀用于制造美甲產品，因為它有助于清潔指甲和溶解角質層；
① Potassium hydroxide is used in the manufacture of nail enhancement products because it helps clean nails and dissolve the cuticle;
②.用于剃須產品，有助于脫毛；
② Used for shaving products, which is helpful for hair removal;
③.生產乳液、洗發水、發膠和其他化妝品的原料，主要用作酸堿度調節劑和PH調節劑。
③. Raw materials for the production of lotion, shampoo, hair gel and other cosmetics, mainly used as pH regulator and pH regulator.
④.不僅假牙清潔劑，烤箱清潔劑、車道和混凝土清潔劑也含有氫氧化鉀。
④ Not only denture cleaners, but also oven cleaners, driveways and concrete cleaners also contain potassium hydroxide.
6、食品工業
6. Food industry
①.氫氧化鉀用于軟化橄欖；
① Potassium hydroxide is used to soften olives;
②.是一種常見的食品添加劑，用于制作汽水、巧克力和可可等；
② . is a common food additive, used for making soda, chocolate, cocoa, etc;
③.可作為冰淇淋等食品的增稠劑和穩定劑；
③ It can be used as a thickener and stabilizer for ice cream and other foods;
④.還有助于制作更脆的烘焙食品，可作為防腐劑添加到食品中；
④ It also helps to make crisper baked goods and can be added to food as a preservative;
⑤.用于生產彩色焦糖；
⑤ For producing colored caramel;
⑥.用于水果和蔬菜的清洗和化學去皮；
⑥ Used for cleaning and chemical peeling of fruits and vegetables;
⑦.有助于延長食物的保質期。
⑦ It helps to extend the shelf life of food.
