氫氧化鉀在紡織中的應用方法

發布來源:http://www.drkkang.com    更新時間:2023-06-21 點擊數:57

氫氧化鉀是一種常見的無機堿,化學式為Koh,分子量為56.1,室溫為白色粉末或片狀固體。類似氫氧化鈉,強堿性,腐蝕性,0.1mol/L溶液,pH13.5。
Potassium hydroxide is a common inorganic base with chemical formula of Koh, molecular weight of 56.1, and white powder or flake solid at room temperature. Similar to sodium hydroxide, strongly alkaline, corrosive, 0.1mol/L solution, pH13.5.
它容易吸收空氣中的水分和潮解,吸收二氧化碳形成碳酸鉀。溶于熱水0.6份,冷水0.9份,乙醇3份,甘油2.5份,略溶于乙醚。當溶解在水、酒精或酸處理時,會產生大量熱量。中度毒性,中致死劑量(大鼠,口服)1230mg/kg。
It easily absorbs moisture and deliquescence from the air, absorbing carbon dioxide to form potassium carbonate. Dissolve in 0.6 parts hot water, 0.9 parts cold water, 3 parts ethanol, 2.5 parts glycerol, slightly soluble in ether. When dissolved in water, alcohol, or acid treatment, a large amount of heat is generated. Moderate toxicity, moderate lethal dose (rat, oral) 1230mg/kg.
氫氧化鉀是固體氫氧化鈉,其化學性能較好。它廣泛應用于農業、工業等領域。今天,小編想介紹它在紡織工業中的應用。讓我們看看。
Potassium hydroxide is a solid sodium hydroxide with good chemical properties. It is widely used in fields such as agriculture and industry. Today, Xiaobian would like to introduce its application in Textile manufacturing. Let's take a look.
1.顏色好
1. Good color
用本品代替純堿灰固定,即用產品的1/10代替純堿灰也能保持較足的供色,少量過量也不會影響纖維在操作過程中的著色。
Using this product instead of soda ash for fixation, even if 1/10 of the product is used instead of soda ash, it can maintain sufficient color supply, and a small amount of excess will not affect the coloring of the fibers during operation.

2.對染料和設備適應性廣
2. Wide adaptability to dyes and equipment
適用于各種活性染料,對不同結構的各種活性染料具有較高的顯色性和重現性。此外,Koh在各種設備上表現出較好的優勢,主要是在低浴比和氣霧染色機上。
It is suitable for all kinds of Reactive dye, and has high color rendering and reproducibility for all kinds of Reactive dye with different structures. In addition, Koh has shown good advantages in various equipment, mainly in low bath ratios and aerosol dyeing machines.
3.縮短染色時間
3. Shorten dyeing time
又稱緩沖固體堿,溶解時電解質少,離子強度低。因此,在加堿過程中,染色速度慢,使染料的勻染性更好。在深色和淺色中,堿可以在20分鐘左右加入,以縮短染色時間。
Also known as buffer solid base, it has less electrolyte and low Ionic strength when dissolved. Therefore, during the alkali addition process, the dyeing speed is slow, resulting in better levelness of the dye. In dark and light colors, alkali can be added in about 20 minutes to shorten the dyeing time.
具有良好的耐蝕性,其次是鎳。銀和鎳能承受氫氧化鈉的濃度和溫度,直到熔化狀態(480℃).適用于高溫高濃度堿、鎳及其合金(如Cr-Ni-Fe合金、Monel合金等),是較好的選擇。
It has good corrosion resistance, followed by nickel. Silver and nickel can withstand the concentration and temperature of sodium hydroxide until melting (480 ℃). It is suitable for high temperature and high concentration alkali, nickel and their alloys (such as Cr Ni Fe alloy, Monel alloy, etc.), and is a good choice.
不銹鋼可承受80-100℃NaOH溶液在40%-50%以下,但不能耐受高濃度的高溫堿。碳鋼在低溫稀NaOH溶液中具有良好的耐蝕性,在表面能形成固體氧化保護膜。由于低廉,氫氧化鉀往往是很多用戶的選擇。更多相關事項就來我們網站http://www.drkkang.com咨詢吧!
Stainless steel can withstand NaOH solutions at temperatures below 40% -50% at 80-100 ℃, but cannot withstand high concentrations of high-temperature alkali. Carbon steel has good corrosion resistance in low temperature dilute NaOH solution and can form a solid oxidation protective film on the surface. Due to its low price, potassium hydroxide is often the choice of many users. For more related matters, come to our website http://www.drkkang.com Consult!
