Pretreatment refers to the electrocleaning and activation treatment of the surface of the plated object to improve the bonding strength between the coating and the object. The electroplating solution to be used in this link is surface treatment solution, mainly including electrocleaning solution and activation solution. The electrocleaning solution is a colorless transparent alkaline aqueous solution with a pH of 13. It can be stored for a long time with low corrosivity. It has strong degreasing ability and slight rust removal effect, and is suitable for electrolytic degreasing of metal surfaces and brush plating surface pretreatment; The activation solution is colorless transparent solution, acidic, PH=0.4, which can be stored for a long time. It has the ability to remove the oxide film and fatigue layer on the metal surface, and has a slow corrosion to the matrix. It is suitable for surface activation treatment of low-carbon steel, low-carbon alloy steel, white cast iron and other materials.
Electroplating equipment Loose coating is a common fault, so we need not be nervous when encountering such a situation, Electroplating wastewater zero discharge manufacturer It is also because the equipment has been working for a long time. How should we deal with it? We should strengthen the polishing of the surface of electroplating equipment, and pay attention to the treatment of activated carbon powder; In this case, there may be a problem with the composition. First, analyze and adjust the normal range; Reduce current density; Increase the positive area.
Electroplating solutions can be divided into surface top treatment solution, deposition metal solution and deplating solution according to different uses. They play a very important role in different links of the electroplating process. Surface top treatment solutions include electrocleaning solution and activation solution, which are important solutions in the pretreatment link and play an important role in electroplating equipment.
