氢氧化钾为白色粉末或片状固体，具强碱性及腐蚀性。极易吸收空气中水分而潮解，吸收二氧化碳而成碳酸钾。溶于约0.6份热水、0.9份冷水、3份乙醇、2.5份甘油。
Potassium hydroxide is a white powder or flake solid with strong alkalinity and corrosiveness. It is easy to absorb moisture in the air and deliquesce, and absorb carbon dioxide to form potassium carbonate. Dissolve in about 0.6 parts of hot water, 0.9 parts of cold water, 3 parts of ethanol and 2.5 parts of glycerin.
氢氧化钾的作用
The role of potassium hydroxide
1、用作干燥剂、吸收剂，用于制草酸及各种钾盐，还用于电镀、雕刻、石印术等。
1. It is used as desiccant, absorbent, oxalic acid and various potassium salts, electroplating, carving, lithography, etc.
2、主要用作钾盐生产的原料，如高锰酸钾、碳酸钾等。在医药工业中，用于生产钾硼氢、安体舒通、沙肝醇、丙酸睾丸素等。在轻工业中用于生产钾肥皂、碱性蓄电池、化妆品（如冷霜、雪花膏和洗发膏）。在染料工业中，用于生产还原染料，如还原蓝RSN等。在电化学工业中，用于电镀、雕刻等。在纺织工业中，用于印染、漂白和丝光，并大量用作制造人造纤维、聚酯纤维的主要原料。此外，还用于冶金加热剂和皮革脱脂等方面。
2. It is mainly used as raw materials for potash production, such as potassium permanganate, potassium carbonate, etc. In the pharmaceutical industry, it is used to produce potassium, boron, hydrogen, spironolactone, salbutamol, testosterone propionate, etc. In light industry, it is used to produce potassium soap, alkaline battery, cosmetics (such as cold cream, cream and shampoo). In dye industry, it is used to produce vat dyes, such as vat blue RSN, etc. In the electrochemical industry, it is used for electroplating, carving, etc. In the textile industry, it is used for printing and dyeing, bleaching and mercerizing, and is widely used as the main raw material for manufacturing man-made fiber and polyester fiber. In addition, it is also used in metallurgy heating agent and leather degreasing.
3、化工基本原料，用于医药、日用化工等。
3. Chemical basic raw materials, used in medicine, daily chemical industry, etc.
4、用作分析试剂、皂化试剂、二氧化碳和水分的吸收剂。
4. It is used as an absorbent of analytical reagent, saponification reagent, carbon dioxide and water.
5、日化工业用作制造洗污肥皂、洗头软皂、雪花膏、冷霜、洗发膏等的原料。制药工业用于制造黄体酮、香兰素等原料。染料工业用于制造三聚氰胺染料。电池工业用于制造碱性蓄电池。
5. The daily chemical industry is used as the raw material for making washing soap, shampoo soap, cream, cold cream, shampoo, etc. Pharmaceutical industry is used to manufacture raw materials such as progesterone and vanillin. The dye industry is used to make melamine dyes. The battery industry is used to make alkaline batteries.
氢氧化钾对皮肤起什么作用
What effect does potassium hydroxide have on the skin
对组织有烧灼作用，可溶解蛋白质，形成碱性变性蛋白质。溶液或粉尘溅到皮肤上，尤其溅到黏膜，可产生软痂。溶液浓度越高，温度越高，作用越强。溅入眼内，不仅可损伤角膜，而且能使眼部深组织损伤。
It has the function of cauterizing tissue, dissolving protein and forming basic denatured protein. Solution or dust splashed on the skin, especially on the mucous membrane, can produce soft scabs. The higher the solution concentration, the higher the temperature and the stronger the effect. Splashing into the eyes can not only damage the cornea, but also damage the deep tissues of the eyes.

最高容许浓度为0.5 mg/m。工作时应防止触及皮肤和眼睛，如不慎触及时，可用流水洗涤受损部位，然后湿敷5%的醋酸、酒石酸、盐酸或柠檬酸溶液；如溅人眼内，应用流水或生理盐水仔细缓慢洗涤10～30 min，然后点入2%的奴佛卡因或0.5%的地卡因溶液。操作时应穿由结实布制作的工作服，戴橡皮手套、袖套、围裙，穿胶鞋等劳保用品，手上宜涂敷中性和疏水软膏。
The maximum allowable concentration is 0.5 mg / m. When working, it should be prevented from touching the skin and eyes. If it is touched in time, the damaged part can be washed with running water, and then 5% acetic acid, tartaric acid, hydrochloric acid or citric acid solution can be wet applied. If it splashes into the eyes, it should be washed carefully and slowly with running water or normal saline for 10-30 min, and then 2% novocaine or 0.5% dicaine solution can be added. During operation, workers shall wear work clothes made of strong cloth, rubber gloves, sleeves, apron, rubber shoes and other labor protection appliances, and apply neutral and hydrophobic ointment on their hands.
