Description
Technical Field
The invention relates to the field of powder coating processing, in particular to a container coating processing technology.
Background
The container is a large-sized loading container with certain strength, rigidity and specification and specially used for turnover. The container is used for transferring goods, the goods can be directly loaded in the warehouse of a shipper and unloaded in the warehouse of a consignee, and the goods do not need to be taken out from the container for reloading when vehicles and ships are changed midway.
When the surface of the existing container is subjected to anti-corrosion treatment, a three-coating and three-baking process of bottom coating paint, middle coating paint and surface coating paint is basically adopted, a large amount of organic solvents such as paint, curing agent, diluent and the like are used in the production process of the container, each paint is dried after being sprayed, a large amount of VOC organized emission can be generated, and the VOC is discharged into the atmosphere after being absorbed by combustion, so that the environmental protection is greatly influenced.
In the production process, due to the volatilization of the organic solvent, even if the staff wears the clothes for labor insurance, the health of the staff is affected; meanwhile, a large amount of paint is used, and the material cost is high.

The technical scheme of the invention is as follows: the method comprises the following steps: preparing a base material, performing primer rust prevention roller coating, welding and forming, performing local shot blasting and repairing local primer shot blasting parts;
further comprising: spraying base powder, spraying flour, baking and curing and inspecting finished products, wherein when the base powder and the flour are sprayed, a spray gun sprays for multiple times, and the interval between adjacent spraying is more than 10 seconds.
The base powder comprises one or more materials of epoxy ester, polyurethane and polybutadiene.
The flour-based food preservative also comprises a preservative layer, wherein the preservative layer is positioned between the base powder and the flour.
The thickness of the base powder layer formed by spraying the base powder is 40-60 mu m.
The thickness of the flour layer formed by spraying flour is 40-55 μm.
The flour comprises one or more materials of polyurethane, inorganic ceramic, polyphenyl ether and polyformaldehyde.
The baking and curing time is 40-50 deg.C and 2-4 min.
