Description

Technical field [0001] The invention relates to the technical field of insulating material preparation, in particular to an acid and alkali resistant insulating material and its production process. Background technique [0002] Industrial storage tanks have been affected by factors such as acid and alkali and other chemicals, industrial sewage, industrial gas, ultraviolet light, solid particles, flow wear, erosion and other factors for a long time. All bearing surfaces have acid and alkali corrosion, atmospheric corrosion, and osmotic cracking. A variety of more complex corrosion forms such as physical erosion and microbial corrosion seriously affect its service life. Therefore, in order to ensure the long-term and 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, ac...

AI Technical Summary

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
