Problems solved by technology

[0006] The LOC box is generally made of metal materials. Since the fan is often in a harsh environment, the LOC box is required to have corrosion resistance and other properties. At present, the corrosion resistance of the LOC box is often increased by coating the method, but the current temperature difference of the LOC box coating , corrosion resistance, aging resistance and mechanical properties cannot be taken into account, which will affect the service life of the fan and cause safety hazards

Abstract

The invention discloses molding powder for electrostatic spraying of an LOC box. The molding powder comprises the following components in parts by weight: 30-35 parts of epoxy resin, 25-30 parts of polyester resin, 10-15 parts of hydroxyl-containing fluorocarbon resin, 4-8 parts of tri-beta-methyl glycidyl isocyanurate, 1-3 parts of triglycidyl isocyanurate, 0.5-1 part of a pigment, 25-30 parts ofa filler, 2-3 parts of a leveling agent, 0.5-1 part of a moisture-proof agent, 0.5-1 part of a corner modifier, 0.5-1 part of benzoin and 1-1.5 parts of a coupling agent. The molding powder has goodcorrosion resistance and high temperature resistance.

Description

technical field [0001] The invention relates to the technical field of plastic powder, in particular to a plastic powder for LOC boxes. Background technique [0002] The fan is a machine that relies on the input mechanical energy to increase the gas pressure and discharge the gas. It is a driven fluid machine. Fan is the customary abbreviation for gas compression and gas conveying machinery in China. Usually, fans include ventilators, unpowered ventilators, blowers, wind generators, etc. [0003] Fans are widely used in ventilation, dust removal and cooling of factories, mines, tunnels, cooling towers, vehicles, ships and buildings, ventilation and induction of boilers and industrial furnaces; cooling and ventilation in air conditioning equipment and household appliances ; Grain drying and selection, wind tunnel wind source and inflation and propulsion of hovercraft, etc. [0004] The main structural components of the fan include the impeller, the casing (that is, the LOC ...
