氢氧化钾的应用非常广泛，除了我们以前的文章中用于生产洗面奶，制备难熔粘合剂，添加在混凝土中，它还可以用于生产除油剂，让我们来详细看看。

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.

它是常用的除油剂之一，能与硬脂酸皂化动植物油，能产生水溶性硬脂酸钠和甘油。但是，当浓度较低时，当pH值小于10.5时，硬脂酸钠会水解，除油效果不是很好。但是，如果浓度过高，硬脂酸钠和表面活性剂的溶解度会降低，导致可洗性差。虽然氢氧化钾可以去除油，但油本身不容易去除。因此，一般用量应在100g/L范围内，且大多数应在50g/L至70g/L之间，以达到良好的清洗效果。

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.

除油液适用于钢、铜及铜合金、铝及铝合金等，除油效果好。但是，在使用时要控制好时间，避免金属的腐蚀。因为它有很强的腐蚀性，所以在使用时要穿戴防护设备。含油的碱性废水在排放前需要中和。它也适用于各种活性染料，当应用于各种活性染料时，其结构具有较好的色彩和再现性。

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.

当我们进行配置时，首先需要准备好850g水注入到脱油池中准备使用，然后再依次加入进去，加入合适剂量的氢氧化钾，还有一些硫酸钠、海藻酸钠等物质，都可以用搅拌装置搅拌均匀；然后再单独准备一个塑料桶倒入进去的水还有助剂等搅拌均匀知道其中的物质完全融化后可以把塑料桶当中国的倒入刚才搅拌均匀的除油池中，这样一个可以用到的除油剂就制成了；大多数金属在除油时只需在除油剂中浸泡10分钟左右，如果在较重的油污上轻轻擦拭一下，几乎可以达到比较好的除油效果，因为其实很多工业中使用的机械配件都会有较大的油污，所以在使用过程中要经常清洗一下，这样才能达到较好的效果。

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.

用氢氧化钾配置除油剂使用时，其实效果往往也是很好的，因为其碱性是没有氢氧化钠那么强的，所以在使用时对手部等伤害也比较小。

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.

以上介绍的是氢氧化钾还可以用作除油剂的事项，此外要注意使用时需要控制用量和时间，避免需要除油的设备被腐蚀。更多相关内容就来我们的网站http://qxu1539600089.my3w.com咨询吧！
