The FRP anti-corrosion project uses corrosion-resistant resin and glass fiber surface felt as the anti-corrosion layer, and unsaturated polyester resin and alkali-free glass fiber cloth as the reinforcement layer, which has high corrosion resistance, good strength and long service life.
In the past two years, it has been widely used in FRP storage tanks, FRP cover plates, FRP air ducts, pickling tanks, liquid storage tanks, building storage tanks, etc. Acid-base workshop, etc. So what are the advantages of FRP anti-corrosion engineering?
1. Lightweight and high strength:
The specific gravity of FRP is only 1.4-2.0. As the main structural material of anti-corrosion equipment, it has the advantages of convenient transportation, installation and maintenance.
2. Excellent corrosion resistance:
One of the biggest characteristics of FRP is its good corrosion resistance. By selecting the type and grade of resin and adopting a suitable molding process, FRP products resistant to various acids, alkalis, salts and organic solvents can be produced.
3. Good surface performance and easy cleaning and sterilization performance:
Since FRP is integrally formed, without joints, and the inner wall is smooth, when in contact with chemical media, there are few corrosion products and scaling on the surface, and it does not breed bacteria and microorganisms.
Therefore, it does not pollute the medium and is easy to clean. After special inspection by the food and drug management department, FRP has met the requirements of the food brewing and pharmaceutical industries.
4. Good designability:
FRP is a composite material that can change its raw material type, quantity ratio and arrangement of reinforcement materials to meet different performance requirements.
5. Good construction technology for FRP anti-corrosion construction:
Uncured resins and reinforcements have the ability to change shape, so they can be easily processed into the desired shape through different molding methods and molds. This feature is suitable for large-scale, integral and structurally complex equipment and construction requirements.
6. Low comprehensive cost:
Due to the advantages of light weight, good corrosion resistance, long service life and less maintenance, FRP has low installation and use costs and comprehensive cost.
Moreover, for some equipment with complicated or harsh conditions of use, the method of taking advantage of each other's strengths can be adopted to achieve the goal of having excellent performance and reducing the cost. Layer thickness to adjust for different media and loads.
7. Anti-aging, flame retardant.
