An antirust device for sheet metal

Abstract

The invention discloses an antirust equipment for metal plates, which comprises a bottom box, a slidable moving box is installed in the middle of the bottom box, and two bottom boxes are formed inside the bottom box on both sides of the moving box. The liquid storage chamber containing the phosphating solution, the filter mechanism is set between the inner wall of the two liquid storage chambers and the outer wall of the moving box, and the top of the bottom box above the two liquid storage chambers is provided with a metal plate for putting in The filter mechanism includes a filter screen, the filter screen is installed between the inner wall of the liquid storage chamber and the outer wall of the moving box, and the filter screen is set as a flexible material, when the filter screen is stretched straight. The present invention achieves the effect of cleaning the filter screen through the cooperation between the structures, and completes the cleaning of the phosphating slag, thereby keeping the phosphating solution clean, further improving the quality of the phosphating film on the surface of the metal plate, and further improving the quality of the metal The corrosion resistance of the plate increases the ratio of qualified products.

Description

technical field [0001] The invention relates to the field of antirust technology, in particular to antirust equipment for metal plates. Background technique [0002] Antirust of metal sheets in metal components is a necessary process for most enterprises at present, so as to improve the corrosion resistance of metal sheets and increase their service life. [0003] There are many anti-rust methods for metal plates. Phosphating is a commonly used pretreatment technology, mainly used for phosphating on the surface of steel. Phosphating is a process in which chemical and electrochemical reactions form phosphate chemical conversion coatings. The formed phosphoric acid Salt conversion film is called phosphating film, and most of the existing phosphating is to put the metal plate into the phosphating tank, and then take out the metal plate after the phosphating is completed, but the phosphating solution will Phosphating slag will be produced. If the phosphating slag is not removed...

[0003] There are many anti-rust methods for metal plates. Phosphating is a commonly used pretreatment technology, mainly used for phosphating on the surface of steel. Phosphating is a process in which chemical and electrochemical reactions form phosphate chemical conversion coatings. The formed phosphoric acid Salt conversion film is called phosphating film, and most of the existing phosphating is to put the metal plate into the phosphating tank, and then take out the metal plate after the phosphating is completed, but the phosphating solution will Phosphating slag will be produced. If the phosphating slag is not removed, the quality of the phosphating film on the surface of the metal plate will be affected, thereby reducing the corrosion resistance of the metal plate, increasing the ratio of unqualified products, and may even affect the normal processing run
