Photospating and slag removal equipment

Short Description:

In the formation of metal surface treatment of phosphate skin film process, will produce a large number of phosphate slag, such as the timely removal of these suspended in the liquid fine slag particles, it will affect the stability and cleanliness of the tank liquid, directly affecting the product qualification rate. Therefore, it is necessary to configure automatic phosphating slag removal machine in the production line.
