Jingzhou new earth fiberglass reinforced plastic chemical characteristics
1, excellent corrosion resistance. One of the biggest features of FRP is good corrosion resistance. According to the working conditions, through the selection of different kinds of resin, choose the appropriate molding process, can produce a variety of acids, alkalis, salts and organic solvents resistant FRP products
2. Lightweight and high strength. The specific gravity of FRP is only 1.4-2.0, and the tensile strength of fiber winding can be up to 300-500Mpa, exceeding the limit strength of ordinary steel, such as the strong design calculation, has reached or exceeded some special alloy steel, so it can be used as the main structural material of anticorrosive equipments and has the advantages of convenient transportation, installation and maintenance. Advantages.
3. Good designability. FRP is a kind of composite material that can change the type of raw materials, quantity ratio and arrangement of reinforcing materials to meet different performance requirements.
4. Good construction process. Uncured resin and reinforcing materials have the ability to change shape, so it can be easily processed into the desired shape by different molding methods and molds. This feature is best suited to large, monolithic and structurally complex equipment and construction requirements for on-site construction and assembly.
5. Good surface performance. Because the FRP is a whole molding without seams, smooth inner wall, and chemical media contact, the surface of few corrosion products and scaling phenomenon, not to mention the breeding of bacteria and microorganisms. Therefore do not contaminate the medium.
6. Aging, flame retardant. FRP is a reinforced plastic category of products, the matrix material there is a natural aging and combustion problems. But the world after more than 60 years, China after more than 30 years of research, has been a preliminary solution, reinforced materials plus coupling agent processing, use 50 years, the bending degree can be maintained at 64-46%, tensile retention rate of 71.2%, such as with anti-aging agent, anti-aging performance is better; fiberglass fiber reinforced plastic matrix to add a flame retardant and the use of fire-retardant resins and then add a flame retardant, the oxygen index of up to 34-36, fully meet the fermentation equipment, flame retardant, flame retardant and flame retardant, the oxygen index of the fiberglass reinforced plastic is a good solution. The oxygen index can reach 34-36, which can fully meet the fire retardant and fire prevention requirements of fermentation equipment.
7. Comprehensive cost is lower. FRP as a new functional materials, due to its use of raw materials prices are high, generally speaking, the price of FRP equipment is higher than carbon steel equipment and some plastic equipment, but lower than stainless steel and other non-ferrous metal equipment. But because of the light weight, good corrosion resistance, long service life, maintenance and other advantages of FRP, its installation, use of cost and comprehensive cost bottom; and for some of the use of complex or harsh conditions of the equipment, can be used to take advantage of the approach, such as heating coil with stainless steel or titanium, lined with thermoplastic, etc., in order to achieve both excellent performance and can reduce the cost of the purpose.
So the life of a qualified fiberglass reinforced plastic products have to be more than 30 years 01768323444
