Abstract

The invention discloses an oil removing and rust removing phosphating solution, which is prepared by mixing zinc nitrate, magnesium chloride, zinc oxide phosphoric acid, thiourea, sodium carbonate, molybdic acid, potassium bichromate and the water. The oil removing and rust removing phosphating solution has a reasonable formula, a good working effect and low production cost.

Description

Technical field: [0001] The invention relates to a phosphating solution for removing oil and rust. Background technique: [0002] The existing degreasing and descaling phosphating solutions generally have certain deficiencies in treatment effect, and the production cost is also relatively high. Invention content: [0003] The object of the present invention is to provide a kind of reasonable formula, good working effect degreasing derusting phosphating liquid. [0004] Technical solution of the present invention is: [0005] A degreasing and derusting phosphating solution is characterized in that it is composed of the following components by weight: [0006] Zinc nitrate 10-20 parts [0007] Magnesium chloride 1~4 parts [0008] Zinc oxide 3~5 parts [0009] Phosphoric acid 10-15 parts [0010] Thiourea 0.1~0.5 parts [0011] Sodium carbonate 5-10 parts [0012] Molybdic acid 0.1~1 part [0013] Potassium dichromate 0.05~0.2 parts [0014] 70-100 parts of water. ...
