Glass Fiber Reinforced Plastic (GFRP) Vertical Storage Tank

Fiberglass storage tanks are a type of fiberglass product, primarily made by wrapping a new composite material around a reinforcement of glass fibers and a binder of resin, all controlled by microcomputer-operated machines. These tanks are known for their corrosion resistance, high strength, lightweight, and long lifespan. Due to their flexible designability and strong processability, they can be adapted for various industries such as chemical, environmental protection, and food processing, gradually replacing most of the market domains of carbon steel and stainless steel.

Fiberglass storage tanks are available in vertical, horizontal, fiberglass, chemical, corrosion-resistant, hydrochloric acid, sulfuric acid, food, fermentation, transport, storage, glue, chemical, pressure, soy sauce, and nitric acid types, among others.

Select epoxy furan resin, modified or polyester resin, or phenolic resin as the binder based on the medium used (storage or transportation). It consists of a corrosion-resistant lining with high resin content, a waterproofing layer, a fiber-reinforced layer, and an outer protective layer.

Fiberglass reinforced plastic products, known for their excellent corrosion resistance, serve as transmission media in many industries. However, what enables them to possess their unique characteristics? The structure of fiber-wound FRP products is divided into three parts: the inner lining layer, the structural layer, and the outer protective layer. The inner lining layer contains a high resin content, usually over 70%, with the resin-rich inner surface having approximately 95%. By selecting the resin for the inner lining, the FRP products can exhibit varying corrosion resistance during liquid transportation, thereby meeting different operational requirements; for applications requiring external corrosion protection, simply carefully selecting the resin for the outer protective layer can achieve the desired external corrosion protection.

Fiberglass products can be customized for different corrosive environments with various types of corrosion-resistant resins, including bisphenol A unsaturated polyester resin, vinyl resin, epoxy resin, and furan resin. For acidic environments, choose bisphenol A and furan resins; for alkaline environments, opt for vinyl, epoxy, or furan resins; for solvent-based applications, select furan resins. In less severe corrosive conditions with acids, salts, or solvents, cheaper m-bisphenol A resins can be used. By selecting different resins for the lining, fiberglass products can be extensively used in acidic, alkaline, saline, and solvent environments, demonstrating excellent corrosion resistance.
