Method and equipment for degreasing acid liquid of packaging steel strip
The method and equipment of acid degreasing are similar to those of lye degreasing. In the degreasing method, the bubble method and soaking corresponding equipment can be used. The operation and equipment are simple and can be used in any factory. Strengthening measures can be taken to improve the speed and efficiency of degreasing. For example, the upper limit of the temperature can be used for degreasing, so that the chemical activity of the acid solution is enhanced at a higher temperature, and the reaction speed and effect are increased. In addition, manual or mechanical stirring can be used to increase the power to promote oil removal, so that the acid can penetrate into the interface between the oil rust layer and the metal surface more quickly, and promote the reaction of the interface horse battery. Factories with conditions can use ultrasonic intensification, which can greatly increase the speed of oil and rust removal. Rinse immediately after soaking and degreasing, and rinse the residual oil, residual rust and acid mixture on the metal surface, and further neutralize with lye or passivation in passivation solution. These measures mainly depend on the next step of the workpiece after the oil removal.
In addition, the acid liquid can also be sprayed or sprayed to remove oil. The spraying method is better than the spraying effect. The spraying has a large flushing force, and it can be sprayed from different angles and directions. The temperature and pressure can be determined according to the rust attached to the surface.
