Problems solved by technology

[0002] Industrial storage tanks have long been affected by factors such as acids and alkalis, industrial sewage, industrial gases, ultraviolet rays, flow wear and erosion of solid particles, and all bearing surfaces have acid-base corrosion, atmospheric corrosion, and penetrating cracking. Various complex corrosion forms such as physical erosion and microbial corrosion seriously affect its service life. Therefore, in order to ensure the long-term effective operation of industrial storage tanks, the anti-corrosion treatment of its bearing surface is particularly critical
Traditional anti-corrosion materials are mostly sodium silicate acid-resistant materials, furan or modified furan acid-resistant materials, acid-resistant bricks, "three cloth and five oil" resin materials and other systems. Insulating materials play an irreplaceable role in our lives. With its wide application, there are also many problems, especially in industrial applications, it is easy to be corroded by chemicals, so the preparation technology of insulating materials needs further research
