Multi -use pickling corrosion agent is a chemical agent, which is mainly used in the pickling process in metal surface treatment, which is used to reduce or reduce the corrosion and damage of the metal surface to the metal surface, and play a role in corrosion and protecting metal.
The ingredients of mostly used the acid erosion can be different according to the specific preparation process and requirements, but generally include the following main components:
Organic corrosion agent: such as nitrobenzene sulfonic acid, nitrobenol, phenylhol, etc. These organic matter can form a chemical adsorption layer with the metal surface to reduce the corrosion of the metal surface on the metal surface.
Ion erosion agent: such as copper ions, zinc ions, etc. These ions can form an electrochemical reaction with the metal surface to generate a stable corrosion layer to reduce the damage to the metal surface.
Surface active agents: such as sodium dulate, sodium consolidated sulfonate, etc. This type of substance can reduce the surface tension of acid washing, improve the moisture and uniformity, so that the pickled liquid can form a more uniform and stable corrosion layer on the metal surface.
Caps: such as sodium hydroxide, sodium bicarbonate, etc. These substances adjust the pH value of acid washing solution to maintain a relatively stable corrosion performance within a certain range.
It should be noted that although mostly a pickled erosion agent can effectively reduce the corrosion and damage of the acidity on the metal surface, it may also cause harm to the human body and the environment, and the amount of usage should be strictly controlled and the processing waste liquid should be strictly controlled. During use, correct operation and disposal should be performed according to relevant safety operation procedures and environmental protection requirements.
