Problems solved by technology

At present, the ventilation hoods in the industry are mostly made of metal materials (aluminum or stainless steel), but the gases generated in industrial production often contain corrosive gases, corrosive gases or water vapor that contain components that are harmful to metal materials, resulting in ventilation. The service life of the hood is greatly reduced, and the ventilation hood needs to be replaced regularly, and the cost of the ventilation hood made of metal material is relatively high, which increases the cost of the enterprise. Therefore, it is necessary to improve the ventilation hood to improve its corrosion resistance and high temperature resistance. and reduce costs

Abstract

The invention relates to a heat-resisting anti-corrosion ventilation hood, and belongs to the technical field of materials. The ventilation hood sequentially comprises a fluorinated resin outer layer,a heat insulation layer, a metal layer and an anti-corrosion enhancement layer from outside to inside. The anti-corrosion enhancement layer is prepared from, by weight, 100 parts of quartz powder, 36-50 parts of granite powder, 23-30 parts of beta-SiC powder, 26-33 parts of epoxy resin, 15-25 parts of a curing agent and 19-29 parts of modified carbon fibers. The ventilation hood is resistant to corrosion and high temperature, long in service life and low in cost.

Description

technical field [0001] The invention belongs to the technical field of materials and relates to a heat-resistant and anti-corrosion ventilation cover. Background technique [0002] Ventilation hoods are widely used in life and industry. For example, the ventilation hood installed in the kitchen can discharge the combustion gas, food smell, steam, etc. generated during the cooking process to the outside, thereby preventing the air in the kitchen from being polluted. Traditional kitchen hoods fit over the gas area of ​​the kitchen. The scope of industrial ventilation hoods is very wide. Metallurgy, mining, machinery, chemical industry, building materials, medicine, health and other industries and departments need to set up ventilation hoods to enclose various gases and dust generated in industrial production. up and pumped out for discharge or further processing. At present, the ventilation hoods in the industry are mostly made of metal materials (aluminum or stainless steel...
