Problems solved by technology

[0002] The existing electrostatic spraying process is relatively complicated, and there is no uniform specification and standard. The quality of sandblasting is uneven. Many repeated processes also make the production efficiency low, increase the labor burden of workers, and at the same time make the market competitiveness of the product not tall
For some operators who have just entered the industry, there is no clear method and process, resulting in frequent mistakes and omissions during operation, and may even cause serious consequences

Embodiment Construction

[0008] The technical solution of the present invention is an electrostatic spraying process, which is characterized in that it includes the following steps: 1) Pretreatment: degreasing, rust removal, phosphating, passivation; this step can remove oil, dust, rust on the surface of the workpiece traces, and a layer of "phosphating layer" that resists corrosion and can increase the adhesion of the spray coating is formed on the surface of the workpiece. A uniform and rough gray phosphating film that is not easy to rust can not only prevent rust but also increase the adhesion of the sprayed layer.

[0009] 2) Using the principle of electrostatic adsorption, evenly spray a layer of powder coating on the surface of the workpiece; the falling powder is recovered through the recovery system, and then reused after sieving; the powder coating is evenly sprayed on the surface of the workpiece, special workpieces (including The location where electrostatic shielding is easy to occur) shou...

Abstract

The invention discloses an electrostatic spraying process. The process is characterized by comprising the following steps that (1) pretreatment is carried out, specifically, deoiling, derusting, phosphorization and passivation are carried out; (2) a layer of powder coating is evenly sprayed to the surface of a workpiece through the electrostatic adsorption principle, and falling powder is recovered through a recovery system and then screened and reused; and (3) high-temperature curing is conducted, specifically, the workpiece coated with the powder coating is pushed into a curing oven and heated to a preset temperature, generally 185 DEG C, then heat preservation is conducted for 15 minutes, and a finished product can be obtained after the workpiece is taken out of the oven and cooled. According to the process, the method is simple, multiple repeated procedures are omitted, and work efficiency is improved.

Description

technical field [0001] The invention relates to an electrostatic spraying process. Background technique [0002] The existing electrostatic spraying process is relatively complicated, and there is no unified specification and standard. The quality of sandblasting is uneven, and many repeated processes also make the production efficiency low, increase the labor burden of workers, and make the market competitiveness of the product at the same time not tall. For some operators who have just entered the industry, there is no clear method and process, resulting in frequent mistakes and omissions during operation, and may even cause serious consequences. Contents of the invention [0003] In view of the above-mentioned defects of the prior art, the technical problem to be solved by the present invention is to provide an electrostatic spraying process, which is simple, eliminates many repetitive procedures, and improves work efficiency. [0004] In order to achieve the above ...
