Vertical Storage Tanks

Introduction:

FRP storage tanks are divided into vertical storage tanks and horizontal storage tanks. The winding material selection of storage tanks must be appropriate, quality priority, and price consideration.

In the actual production, the tank wall structure of the FRP-wound storage tank is generally an inner liner layer, a strength layer and an outer surface layer.

Material and resin selection:

Due to the different functions of the layers, the materials are selected differently, and the inner liner is directly in contact with the medium, and the material selection is correct or not, which plays a key role in controlling the leakage of the wound storage tank.

To use vinyl resin if store acidic medium, to use bisphenol A resin if store alkali medium, to use alkali-free glass fiber if need to be water and alkali resistant, to use medium-alkali glass fiber if need to be acid-resistant , and the inner liner is made of surface felt and chopped together to reinforce to increase the amount of glue and enhance the impermeability.

The strength layer mainly meets the strength and stiffness requirements of the storage tank. Material selection should fully consider that the selected resin matrix must have good penetrability with the glass fiber for winding to form a dense structural layer; the outer surface is in direct contact with the external environment, and the material is selected according to the aging resistance requirement.

Application:

FRP tanks can be used to store tanks of various media. They are resistant to pressure, corrosion, ageing, long service life, light weight, high strength, impermeability, heat insulation, insulation, non-toxicity and smooth surface. It is widely used in coatings, pharmaceuticals, building materials, chemicals, pigments, resins, food, scientific research and other industries.
