    有机溶剂可以用来清除环氧地坪表面油污

    环氧地坪漆在使用过程中被油污污染是很常见的状况,今天环氧地坪漆厂家就教大家一种很普遍的除油方法---有机溶液除油法,除油效率高,且适用于各种油污。常用的除油污有机溶剂主要有:汽油、酒精、石脑油、苯、甲苯、二甲苯、丙酮、二氧甲烷等等都是常用的有机溶剂,选择有机溶剂要注意,要求是溶解力强、不易着火、毒性小、挥发性慢等。

    It is a common situation that epoxy floor paint is polluted by oil pollution in the use process. Today, epoxy floor paint manufacturers teach you a very common degreasing method - organic solution degreasing method, which has high degreasing efficiency and is suitable for all kinds of oil pollution. The commonly used organic solvents for removing oil pollution are gasoline, alcohol, naphtha, benzene, toluene, xylene, acetone, methane dioxide, etc. They are commonly used organic solvents. When choosing organic solvents, attention should be paid to their strong solubility, difficulty in ignition, low toxicity and slow volatility.有机溶剂除油污主要采用手工擦拭,即用刷子或抹布蘸取有机溶剂,直接在待处理表面擦拭。该法劳动强度大,除油效果较差。要注意溶剂和擦拭布的清洁问题,以免造成二次污染。有机溶剂的除油速度很快,对基材的腐蚀作用也较小,但是除油不够彻底,要用到溶剂二次除油或者是其他除油方法进行补充处理,才能彻底除尽残留在基面上的油脂。

    Organic solvent is mainly used to remove oil stains by hand, that is, brush or cloth dipped in organic solvent, directly wiped on the surface to be treated. This method has high labor intensity and poor oil removal effect. Attention should be paid to the cleaning of solvents and wipes so as to avoid secondary pollution. Organic solvents degrease quickly and have less corrosion on substrates, but degreasing is not complete enough. Secondary solvent degreasing or other degreasing methods should be used for supplementary treatment in order to completely remove the remaining grease on the substrates.有机溶剂除油污适用于一些脱脂量小、机械水平不高或是有特殊要求的部位使用,对于去除碱液难于除尽的高黏度油脂,具有特殊的效果。在除油后,溶剂挥发迅速,有害物质残留较少,可节省水洗、干燥等步骤而直接进入下道工序。但是有机溶剂是具有毒性的,对作业人员的健康以及环境污染都有害,所以建议施工现场要通风。像地下室就不推荐这样的方法。

    Organic solvent degreasing is suitable for some parts with small degreasing capacity, low mechanical level or special requirements. It has special effect on removing high viscosity grease which is difficult to remove from alkali liquor. After oil removal, the solvent evaporates rapidly and the harmful substances remain less, which can save the steps of washing and drying and directly enter the next process. However, organic solvents are toxic, harmful to the health of workers and environmental pollution, so it is suggested that the construction site should be ventilated. Such a method is not recommended in basements.
