Problems solved by technology

[0002] Most mechanical equipment needs anti-slip and anti-corrosion paint on the surface, so as to prolong the life of the entire equipment. However, the traditional painting process knowledge will be directly sprayed on the surface of the equipment, causing problems such as easy peeling off, making the equipment more susceptible to corrosion. Shorten the service life and increase the cost of use

Embodiment Construction

[0018] A kind of painting and drying process of the present invention, the steps are as follows:

[0019] a. Degreasing, to remove the oil stains on the surface of ferrous metal workpieces during the production process, use the tank immersion method; to remove the oil stains on the surface of ferrous metal workpieces during the production process, use the tank immersion method. Alkaline cleaning formula: 5% sodium hydroxide, 5% sodium phosphate, 5% trisodium phosphate, 0.2% OP-10 emulsion, temperature 93~98℃, treatment time 8~10 minutes. Inspection method after treatment: After washing with water, use a brush to check whether the oil stains have been removed.

[0020] b. Cleaning;

[0021] c. Rust removal, use acid to remove rust, remove rust on the steel surface, use tank immersion method; pickling and rust removal liquid formula: industrial hydrochloric acid with a concentration of 42%, corrosion inhibitor 8%, temperature: normal temperature. Processing time 5-10 minutes. ...

Abstract

The invention relates to a paint spraying and drying process. The paint spraying and drying process comprises the following steps: a) oil removal: removing oil stains on the surface of a black metal workpiece during production by using a tank leaching method; b) washing; c) rust removal: removing rust on the surface of steel or iron by using acid and the tank leaching method; d) washing; e) surface conditioning: performing surface treatment before phosphorization by using the tank leaching method; f) phosphorization: phosphorizing the surface of steel or iron by using zinc series phosphorizing solution and the tank leaching method; g) washing; h) drying; i) spraying. The paint spraying and drying process has the advantages that the spraying effect is better through the tank leaching method in all links and proportioning of all components, the paint is not apt to fall; since a special drying process is adopted, the adhering time is especially prolonged and the use cost of mechanical equipment is reduced.

Description

technical field [0001] The invention relates to the technical field of spraying, in particular to a painting process. Background technique [0002] Most mechanical equipment needs anti-slip and anti-corrosion paint on the surface, so as to prolong the life of the entire equipment. However, the traditional painting process knowledge will be directly sprayed on the surface of the equipment, causing problems such as easy peeling off, making the equipment more susceptible to corrosion. The service life is shortened and the cost of use is increased. Contents of the invention [0003] In order to overcome the above-mentioned problems in the traditional spraying process, the present invention provides a spraying and drying process that is not easy to fall off after spraying. [0004] The technical scheme that the present invention adopts for realizing the above object is: a kind of painting and drying process, comprises the following steps: [0005] a. Degreasing, remove t...
