All kinds of FRP vertical storage tanks, transportation tanks, containers and large series containers produced are made of epoxy unsaturated vinyl polyester resin as binder according to the medium used by users (storage or transportation), which is composed of high resin content corrosion-resistant lining layer, impervious layer, fiber winding reinforcement layer and external protective layer. The working temperature of the product is between -50 ~ 120 ℃, and the pressure resistance is generally below 6.4Mpa. It has the advantages of pressure resistance, corrosion resistance, aging resistance and long service life. It has the characteristics of light weight, high strength, anti-seepage, heat insulation, insulation, non-toxic and smooth surface. It can be widely used in petroleum, chemical industry, textile, printing and dyeing, electric power, transportation, food brewing, artificial synthesis, water supply and drainage, seawater desalination, water conservancy irrigation and national defense engineering. It can store all kinds of corrosive media (such as acid, alkali, salt, sewage, drinking water, desalted water, soy sauce, vinegar, beer, milk, etc.), and can also be used as underground oil tank, thermal insulation storage tank, transportation tank car, etc.
·Excellent physical properties of FRP containers and FRP storage tanks: the specific gravity of FRP is usually 1.8-2.1, which is 1 / 4-1 / 5 of that of steel, which is higher than the specific strength of steel, cast-in-place and plastic. The thermal expansion coefficient of FRP is roughly the same as that of steel, and the thermal conductivity is only 0.5% of that of steel.
·FRP containers and FRP storage tanks are resistant to chemical corrosion and have long service life: FRP has special corrosion resistance. When storing corrosive media, FRP shows incomparable advantages over other materials and can resist a variety of acids, alkalis, salts and organic solvents.
·The design flexibility of FRP container and FRP storage tank is large, and the structural performance of tank wall is excellent: fiber wound FRP can change the resin system or reinforcement materials to the physical and chemical properties of high-speed FRP storage tank and non-standard devices, so as to meet the needs of different media and working conditions. Through the structure and design of structural layer thickness, winding angle and wall thickness, the bearing capacity of the tank body is adjusted to make FRP storage tanks and non-standard devices with different pressure levels or some special properties, which can not be compared with isotropic metal materials.
Application scope of vertical FRP storage tank and FRP container:
FRP containers are widely used in the fields of chemical industry, petroleum, papermaking, food, electronics, pharmacy, packaging and transportation. It can resist the corrosion of various acids, alkalis, salts and organic solvents. Application of vertical FRP storage tank and FRP container:
·Acid resistant storage tank (hydrochloric acid tank, sulfuric acid tank, phosphoric acid tank, nitric acid tank, organic acid tank, fluorosilicic acid tank, hydrofluoric acid tank, etc.)
·Alkali resistant storage tank
·Brine storage tank, sewage storage tank
·Food grade FRP storage tanks (FRP vinegar storage tank, FRP vinegar container, FRP soy sauce container, FRP soy sauce storage tank, FRP pure water storage tank, FRP pure water container, etc.) FRP / polyvinyl chloride (FRP / PVC), FRP / polypropylene (FRP / PP) composite tanks adopt e-galss high tension, multi-level, multi angle, multi tangent point, wrapped head The integral inflatable bag winding method meets the needs of flammable media and environmental resistance, the storage, transfer and production of organic and inorganic solvents and chemically and electrochemically corrosive media, the transfer, transportation and elimination of static electricity of non electrolyte fluids, and the mechanical requirements of resisting all kinds of supporting shear, burial and load. The FRP horizontal container has high mechanical strength, good corrosion resistance, long service life, light weight and thermal insulation, With insulation and other series characteristics, the user can save energy, improve carrying capacity and reduce maintenance costs. It can be widely used to store all kinds of chemical corrosive liquid materials.
FRP storage tank: alkali resistant storage tank, brine storage tank, sewage storage tank, food grade FRP storage tank (FRP vinegar storage tank, FRP vinegar container, FRP soy sauce container, FRP soy sauce storage tank, FRP pure water storage tank, FRP pure water container, etc.), FRP / polyvinyl chloride (FRP / PVC), FRP / polypropylene (FRP / PP) composite tank.
