FRP desulfurization tower series
Chemical storage tank
FRP chemical storage tanks have excellent physical properties. The specific gravity of FRP chemical storage tanks is usually 1.8-2.1, which is 1 / 4-1 / 5 of steel. They have higher specific strengths than steel, cast iron, and plastic. The coefficient of thermal expansion is roughly the same as that of steel. Equivalently, the thermal conductivity is only 0.5% of steel. FRP chemical storage tank has great design flexibility, excellent wall structure performance, chemical resistance, and long service life. With light weight, high strength, anti-seepage, anti-corrosion, heat insulation, insulation, non-toxic, smooth surface and so on.
FRP chemical storage tank can adjust the physical and chemical properties of the product by changing the resin variety or using different reinforcement materials to meet the needs of different media liquids and working conditions. Different pressures are designed by the thickness of the structural layer, the winding angle and the wall thickness. It is fiber winding. The salient features of FRP chemical storage tanks.
1. Manufacturing process
Controlled by a computer, an inner lining (such as an anti-corrosion inner lining) is made on the core mold as required. After gelation, the structural layer is wound according to the specified line shape and thickness, and finally a protective layer is made.
2. Raw and auxiliary materials
Resin, fiber felt, glass fiber winding yarn, etc.
3. Product production and inspection standards
In order to ensure the high quality and specific performance requirements of the product from beginning to end, it is extremely important to strictly control each production process, the choice of raw materials and the final product inspection of each process.
The inspection of FRP storage tanks and devices is a comprehensive quality assurance system.The system requires that the raw materials and auxiliary materials have a certificate of compliance from the manufacturer and meet the quality and technical indicators of the product. Full inspection and random inspection are performed before production. At the same time, various tests and inspections such as physical mechanics of the corresponding performance requirements for products such as FRP storage tanks and devices are performed.
Under normal circumstances, national or industry standards are implemented, and specified manufacturing processes and product performance inspections are performed. If there are special requirements, domestic and international relevant standards are required for inspection.
