Analysis of degreasing method of degreasing agent!

In fact, in the chemical industry, if you want to understand the use of a product, we must first know the main ingredients of the product, and there are many formulas of degreasers, which can be divided into three types: neutral, alkaline and acidic. The composition of the general degreaser is scientifically configured by surfactants, detergents, penetrants, detergents, etc., which has good wetting, solubilization and emulsification capabilities, and has a strong ability to remove oil.

The principle of action of degreaser is to use the saponification or emulsification of grease in the alkaline medium, and under the synergistic action of the auxiliary, fine-graine the grease and dirt to remove it from the metal surface, and remove the saponifying or non-saponifying oil, so as to achieve the effect of cleaning, which is the principle of degreaser. Next, let's talk about the issue that everyone is concerned about, that is, the use of degreaser with water.

Some details that need to be paid attention to in the use of degreaser, the operation needs to frequently observe the cleaning status of the workpiece, and if there is a lot of oil stains on the surface, it can be skimmed off. In addition, in the process of using the degreaser, due to the consumption of its main components, its cleaning power gradually decreases, it is best to analyze its concentration once per shift in production, and then add the degreaser according to the analysis results, and it is recommended to use a container to dissolve the degreaser before adding it to the working liquid.

After long-term use, the degreaser will turn yellow and age, and when the effect of adding degreaser is not significant, the tank liquid should be replaced in time. (Judge whether the oil stain is removed: put the degreased workpiece in the water and pick it up to see if the water flow on the surface of the workpiece is smooth and bright, smooth and bright means that the oil has been cleaned, if you pick up the surface of the workpiece and the water beads prove that the oil has not been cleaned).
