What are the spray lining processes for making FRP storage tanks?

The spray lining process for the production of FRP storage tanks mainly includes the following:

Manual coating method: The acid and alkali resistant, corrosion resistant polyurethane or epoxy resin is coated on the inner wall of the glass fiber reinforced plastic storage tank to form a uniform coating. This method is suitable for small tanks and irregularly shaped tanks.

Spraying method: Use professional spraying equipment to spray polyurethane or epoxy resin and other coatings on the inner wall of the glass fiber reinforced plastic storage tank to form a uniform coating. This method is suitable for large storage tanks and regular shaped storage tanks.

Vacuum adsorption method: The coating such as polyurethane or epoxy resin is attached to the inner wall of the glass fiber reinforced plastic storage tank through vacuum adsorption technology to form a uniform coating. This method is suitable for special shaped tanks and applications where high quality coatings are required.

Coating method: The coating such as polyurethane or epoxy resin is coated on polyester felt or glass fiber cloth, and then pasted on the inner wall of the glass fiber reinforced plastic storage tank to form a uniform coating. This method is suitable for applications where enhanced coating thickness and corrosion resistance are required.

In short, there are a variety of options for the spray lining process of FRP storage tanks, and the appropriate process and materials need to be selected according to the actual situation to ensure the quality of the coating and the safety of the storage tank.
