The characteristics of FRP material

What are the characteristics of glass fiber reinforced plastics?
1) Meet the requirements of food hygiene. Whether it can meet the food hygiene requirements is the fundamental requirement of fermentation equipment. Whether FRP products can meet the hygienic requirements depends on the selection of lining resin, that is, the selection of food-grade resin.
2) Lightweight and high strength. The specific gravity of FRP is only 1.4-2.0, while the tensile strength of fiber-wound FRP can reach 300-500Mpa, exceeding the limited strength of ordinary steel. If calculated according to this strength, it has also reached or exceeded some special alloy steel, so it can be used as It is the main structural material of anti-corrosion equipment, and has the advantages of convenient transportation, installation and maintenance.
3) Excellent corrosion resistance. One of the characteristics of FRP is its good corrosion resistance. By selecting the type and grade of resin and adopting a suitable molding process, FRP products that are resistant to various acids, alkalis, salt oils and organic solvents can be produced.
4) Good surface performance and easy cleaning and sterilization performance. Since FRP is integrally formed without joints and the inner wall is smooth, when it meets 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.
5) Good designability. FRP is a composite material that can change its original type, quantity ratio and arrangement of reinforcement materials to meet different performance requirements.
6) Good construction technology. 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, and is suitable for on-site construction and assembly.
7) Anti-aging, flame retardant. FRP is a product in the category of reinforced plastics, and the matrix material has the problems of natural aging and burning. However, after more than 60 years in the world and more than 30 years of research in China, the lining step has been solved. The reinforced material is treated with a coupling agent. After 50 years of use, the bending strength can be maintained at 64-46%, and the tensile strength retention rate is at 71.2, if anti-aging agent is added, the anti-aging performance will be better; adding flame retardant to the fiberglass matrix or using flame-retardant resin to add flame retardant, the oxygen index can reach 34-36, fully meeting the flame retardant and fire prevention of fermentation equipment Require.
