氫氧化鉀的應(yīng)用非常廣泛，除了我們以前的文章中用于生產(chǎn)洗面奶，制備難熔粘合劑，添加在混凝土中，它還可以用于生產(chǎn)除油劑，讓我們來詳細(xì)看看。

The application of potassium hydroxide is very extensive. In addition to our previous articles on producing facial cleansers, preparing refractory adhesives, and adding them to concrete, it can also be used to produce degreasing agents. Let's take a closer look.

它是常用的除油劑之一，能與硬脂酸皂化動植物油，能產(chǎn)生水溶性硬脂酸鈉和甘油。但是，當(dāng)濃度較低時，當(dāng)pH值小于10.5時，硬脂酸鈉會水解，除油效果不是很好。但是，如果濃度過高，硬脂酸鈉和表面活性劑的溶解度會降低，導(dǎo)致可洗性差。雖然氫氧化鉀可以去除油，但油本身不容易去除。因此，一般用量應(yīng)在100g/L范圍內(nèi)，且大多數(shù)應(yīng)在50g/L70g/L之間，以達(dá)到良好的清洗效果。

It is one of the commonly used degreasing agents, which can saponify animal and vegetable oils with stearic acid and produce water-soluble sodium stearate and glycerol. However, when the concentration is low and the pH value is less than 10.5, sodium stearate will hydrolyze and the oil removal effect is not very good. However, if the concentration is too high, the solubility of sodium stearate and surfactants will decrease, leading to poor washability. Although potassium hydroxide can remove oil, the oil itself is not easily removed. Therefore, the general dosage should be within the range of 100g/L, and most should be between 50g/L and 70g/L to achieve good cleaning results.

除油液適用于鋼、銅及銅合金、鋁及鋁合金等，除油效果好。但是，在使用時要控制好時間，避免金屬的腐蝕。因為它有很強的腐蝕性，所以在使用時要穿戴防護(hù)設(shè)備。含油的堿性廢水在排放前需要中和。它也適用于各種活性染料，當(dāng)應(yīng)用于各種活性染料時，其結(jié)構(gòu)具有較好的色彩和再現(xiàn)性。

Oil removal fluid is suitable for steel, copper and copper alloys, aluminum and aluminum alloys, etc., with good oil removal effect. However, it is important to control the time during use to avoid metal corrosion. Because it has strong corrosiveness, it is necessary to wear protective equipment when using it. Alkaline wastewater containing oil needs to be neutralized before discharge. It is also suitable for various reactive dyes, and when applied to various reactive dyes, its structure has good color and reproducibility.

當(dāng)我們進(jìn)行配置時，需要準(zhǔn)備好850g水注入到脫油池中準(zhǔn)備使用，然后再依次加入進(jìn)去，加入合適劑量的氫氧化鉀，還有一些硫酸鈉、海藻酸鈉等物質(zhì)，都可以用攪拌裝置攪拌均勻；然后再單獨準(zhǔn)備一個塑料桶倒入進(jìn)去的水還有助劑等攪拌均勻知道其中的物質(zhì)完全融化后可以把塑料桶當(dāng)?shù)牡谷雱偛艛嚢杈鶆虻某统刂?，這樣一個可以用到的除油劑就制成了；大多數(shù)金屬在除油時只需在除油劑中浸泡10分鐘左右，如果在較重的油污上輕輕擦拭一下，幾乎可以達(dá)到比較好的除油效果，因為其實很多工業(yè)中使用的機械配件都會有較大的油污，所以在使用過程中要經(jīng)常清洗一下，這樣才能達(dá)到較好的效果。

When we configure, we need to prepare 850g of water to be injected into the deoiling tank for use first, and then add it in turn, adding appropriate amounts of potassium hydroxide, as well as some sodium sulfate, sodium alginate and other substances, which can be stirred evenly with a stirring device; Then prepare a separate plastic bucket and pour the water and additives into it. Stir until the substances inside are completely melted, and then pour the plastic bucket into the oil removal tank that was just stirred evenly. This way, a usable oil removal agent is made; Most metals only need to be soaked in a degreasing agent for about 10 minutes when degreasing. If you gently wipe on heavy oil stains, you can almost achieve a good degreasing effect, because many mechanical components used in industry can have large oil stains. Therefore, it is necessary to clean them frequently during use to achieve good results.

用氫氧化鉀配置除油劑使用時，其實效果往往也是很好的，因為其堿性是沒有氫氧化鈉那么強的，所以在使用時對手部等傷害也比較小。

When using potassium hydroxide as a degreaser, the effect is often very good because its alkalinity is not as strong as sodium hydroxide, so the damage to hands and other parts is relatively small during use.

以上介紹的是氫氧化鉀還可以用作除油劑的事項，此外要注意使用時需要控制用量和時間，避免需要除油的設(shè)備被腐蝕。更多相關(guān)內(nèi)容就來我們的網(wǎng)站http://www.jsyjs.net咨詢吧！
