Problems solved by technology

[0003] The working environment of outdoor cabinets is generally poor, and they are basically in the open air, underground humidity, acid-base vapor, and various harsh working conditions. However, most of the current outdoor cabinets do not have anti-corrosion functions, and their service life is relatively long, and the base is extremely easy to damage. Defects such as cracks, curling and even perforation and holes appear due to corrosion and rust; during the long-term use of outdoor cabinets, it is very easy to cause short-circuit and power failure accidents due to rain, moisture, insects and rodents, etc., which consumes a lot of electronics. At the same time, it seriously affects the stable operation of the control system, causing the process production to be in a major safety hazard for a long time

Abstract

The invention discloses a corrosion resistant spraying coating method for an outdoor cabinet base. The method comprises the steps that (1), sanding treatment is conducted on the outdoor cabinet base,and the outdoor cabinet base is soaked in an oil removing solution, washed clean by clear water and dried; (2), the dried outdoor cabinet base is placed into a phosphatizing tank to be soaked; (3), ahigh-temperature rubber belt is bonded to the outdoor cabinet base obtained in step (2), and the outdoor cabinet base is hung; (4), zinc-enriched powder coat is sprayed onto the outdoor cabinet base by adopting a friction gun or a conventional electrostatic gun, and the outdoor cabinet base is put into a convection oven to be cured for the first time after the inspection is qualified; (5), outdoorpowder is sprayed within 48 h after primer is semi-cured or gelatinized; the outdoor cabinet base is put into a curing furnace to be cured again after the inspection is qualified; (6), the outdoor cabinet body is taken down after the temperature of the surface of the outdoor cabinet base is lower than 45 DEG C, and the corrosion resistant outdoor cabinet base is obtained after the inspection is qualified. The method has the advantages that the base of the outdoor cabinet can be effectively protected to achieve the purposes of rusting preventing, corrosion resisting and prolonging the servicelife, and the demand of the long term use of an outdoor cabinet in a severe environment is met.

Description

technical field [0001] The invention belongs to the technical field of anticorrosion cabinets, and in particular relates to an anticorrosion spraying method for the base of an outdoor cabinet. Background technique [0002] Outdoor cabinet refers to the cabinet that is directly under the influence of natural climate, made of metal or non-metallic materials, and does not allow unauthorized operators to enter and operate.
