During customized processing of aluminum profiles, in order to better reduce the sliding friction between NC blades and materials, some emulsions are required. After processing of aluminum parts, the residual smooth oil on them is difficult to be removed by simple scrubbing. This requires the removal of special degreasing agent.
At present, the common degreasing agents are alkaline and acidic. The method of alkaline degreasing is to soak the aluminum profile product in sodium hydroxide solution for alkali corrosion, and then put it into 15-20 sodium cyanide aqueous solution for ash removal, grinding and polishing. This is also the pretreatment process flow of surface anodizing treatment.
However, some aluminum profile manufacturers do not do well and are often depressed because of the deposition problem of aluminum oxide and the concentration of sodium cyanide. Therefore, some manufacturers will choose acidic degreaser to remove oil. The application methods of acidic degreaser and alkaline degreaser are different.
1、 Oil and ash removal by soaking:
1. A small amount of drinking water before application, and then infiltrate the aluminum workpiece into the pool( Adjust the ash remover);
2. Participate in metal aluminum degreasing agent, and fully automatic ironing in 5-10 seconds;
3. After 2 ~ 3 minutes of degreasing, clean it with drinking water;
4. Ash into the ash remover (the time shall not exceed 30 seconds);
5. Drinking water cleaning - drying treatment (drying) or termination of air oxidation.
In the whole process of this application, when the heating temperature of degreaser is high, drinking water diluent degreaser can be added appropriately.
2、 Self spraying oil removal and ash removal:
1. Add appropriate water diluent, oil remover and ash remover;
2. Adjust the angle of view of the nozzle;
3. Ensure the self spraying time of aluminum profile products (no less than 30 seconds);
4. Ensure that the metal aluminum is cleaned with circulating system water;
