氫氧化鉀是一種常見(jiàn)的無(wú)機堿，化學(xué)式為KOH，分子量為56.1，室溫下為白色粉末或片狀固體。性質(zhì)類(lèi)似氫氧化鈉，強堿性，腐蝕性，0.1mol/L溶液pH為13.5。它很容易吸收空氣中的水分和潮解，吸收二氧化碳形成碳酸鉀。溶于約0.6份熱水、0.9份冷水、3份乙醇和2.5份甘油，微溶于乙醚。當溶于水、酒精或用酸處理時(shí)，會(huì )產(chǎn)生大量熱量。中等毒性，半數致死劑量(大鼠，口服)1230毫克/千克。
Potassium hydroxide is a common inorganic base. Its chemical formula is KOH and its molecular weight is 56.1. It is a white powder or flake solid at room temperature. The properties are similar to sodium hydroxide, strongly alkaline and corrosive. The pH of 0.1mol/l solution is 13.5. It is easy to absorb moisture and deliquescence in the air and absorb carbon dioxide to form potassium carbonate. Soluble in about 0.6 parts of hot water, 0.9 parts of cold water, 3 parts of ethanol and 2.5 parts of glycerol, slightly soluble in ether. When dissolved in water, alcohol or treated with acid, a lot of heat will be generated. Moderately toxic, LD50 (rat, oral) 1230 mg / kg.

氫氧化鉀是固態(tài)氫氧化鈉，它的化學(xué)性質(zhì)特別好。廣泛應用于農業(yè)、工業(yè)等方面。今天，小編想介紹它在紡織工業(yè)中的應用。我們來(lái)看看。
Potassium hydroxide is solid sodium hydroxide, and its chemical properties are particularly good. It is widely used in agriculture, industry and so on. Today, Xiaobian wants to introduce its application in the textile industry. Let's see.
1.可以成型出良好的顏色
1. Good color can be formed
用本產(chǎn)品代替純堿固色，即使用1/10量代替純堿，也能保證足夠的給色量，少量過(guò)量不會(huì )影響纖維在操作過(guò)程中的著(zhù)色。
Using this product instead of soda ash for color fixation, that is, using 1 / 10 amount instead of soda ash can also ensure sufficient color giving amount, and a small amount of excess will not affect the coloring of fiber during operation.
2.對染料和設備的廣泛適應性
2. Wide adaptability to dyes and equipment
適用于各種活性染料，對各種不同結構的活性染料具有較高的顯色性和重現性。此外，氫氧化鉀在各種設備上顯示出其獨特的優(yōu)勢，尤其是低浴比和氣溶膠染色機。
It is suitable for all kinds of reactive dyes and has high color development and reproducibility for all kinds of reactive dyes with different structures. In addition, potassium hydroxide shows its unique advantages in various equipment, especially low bath ratio and aerosol dyeing machine.
3.縮短染色時(shí)間
3. Shorten dyeing time
氫氧化鉀也可稱(chēng)為緩沖固體堿，其電解質(zhì)較少，溶解時(shí)離子強度低。所以在加堿過(guò)程中著(zhù)色較慢，使染料勻染性更好。無(wú)論染深色還是淺色，都可以在20分鐘左右加入堿，從而縮短染色時(shí)間。
Potassium hydroxide, also known as buffered solid base, has less electrolyte and low ionic strength when dissolved. Therefore, the dyeing is slow in the process of adding alkali, so that the levelness of the dye is better. Whether dyeing dark or light colors, alkali can be added in about 20 minutes to shorten the dyeing time.
