除油劑的原料有很多,固體氫氧化鉀就是其中之一,但它是腐蝕性的,所以很多用戶不禁要問,能否用這種材料作為除油劑的原料?這就是問題所在。
There are many raw materials for oil remover, among which solid potassium hydroxide is one, but it is corrosive, so many users can't help asking whether this material can be used as the raw material for oil remover? That's the problem.
該產(chǎn)品是一種常用的脫油劑,它皂化動(dòng)物油和植物油中的硬脂酸,生產(chǎn)水溶性硬脂酸鈉(肥皂)和甘油(甘油)。當(dāng)氫氧化鉀濃度過低,pH值為10.5時(shí),硬脂酸鈉水解,除油效果降低。濃度過高,會(huì)降低硬脂酸鈉和表面活性劑的溶解度,使洗滌性能變差,后油不容易洗滌。因此,固體氫氧化鉀的用量一般不超過100g/L,一般在50g/L到70g/L之間。
It saponifies stearic acid in animal oil and vegetable oil, and produces water-soluble sodium stearate (soap) and glycerin (glycerin). When the concentration of KOH is too low and the pH value is 10.5, the hydrolysis of sodium stearate will reduce the oil removal effect. If the concentration is too high, the solubility of sodium stearate and surfactant will be reduced, the washing performance will be poor, and the oil after washing will not be easy. Therefore, the dosage of solid potassium hydroxide is generally no more than 100g / L, generally between 50g / L and 70g / L.
用其制成的除油液適用于除鋼、銅及銅合金、鋁及鋁合金(鋁及鋁合金的除油時(shí)間應(yīng)嚴(yán)格控制在1分鐘以內(nèi),以免腐蝕)。固體氫氧化鉀是一種強(qiáng)腐蝕劑,在使用時(shí)要穿戴防護(hù)裝備,注意,含氫氧化鉀的含油廢水應(yīng)經(jīng)過中和處理后再排放。
The degreasing liquid made of it is applicable to steel, copper and copper alloy, aluminum and aluminum alloy (the degreasing time of aluminum and aluminum alloy shall be strictly controlled within 1 minute to avoid corrosion). Solid potassium hydroxide is a kind of strong corrosive agent. Wear protective equipment and pay attention to safety when using. The oily wastewater containing potassium hydroxide should be neutralized before discharging.
熟悉固體氫氧化鉀脫油劑的使用范圍,可以恢復(fù)基體表面的清潔,保持基體表面的完整性,減少磨損,延長(zhǎng)基體的使用壽命。因此,本產(chǎn)品可用作脫油劑。
Familiar with the application range of solid potassium hydroxide deoiling agent can restore the cleanness of the substrate surface, maintain the integrity of the substrate surface, reduce wear and prolong the service life of the substrate. Therefore, this product can be used as deoiling agent.
