Purmoral corrosion agent is a chemical solution for removing metal surface oxidation, rust and other pollutants. Common pickled corrosion formulas mainly include acidic ingredients such as hydrochloric acid or sulfuric acid, as well as additives to enhance the cleaning effect. The following is a conventional pickled corrosion agent formula:
Hydrochloric acid or sulfuric acid: as an acidic ingredient, it is used to dissolve and remove oxidation layers, rust and other pollutants on the metal surface. The acid concentration in the formula is adjusted as required.
Surface active agent: These additives help reduce the surface tension of the liquid, making the acid washing liquid easier to cover and wet the metal surface. Surface active agents can also improve the penetration of acid washing, making it easier to enter tiny pores and cracks.
Correspondence: These additives can reduce the corrosion of acid on metal and form a protective membrane to prevent excessive corrosion. Common corrosion agents include organic acids, complexing agents and phosphates.
Cushion: Because the pH value of the pickled solution is low, in order to stabilize the acidity of the acid washing fluid and reduce the change of the pH value, the buffer can be added. Common buffers include phosphate and boric acid.
It should be noted that the specific proportion and ingredients of the pickling corrosion formula will be different according to different applications and metal materials. In order to ensure safety and effect, please conduct formulas and use it under professional guidance, and strictly abide by relevant safety operating procedures.
