1) Meet food hygiene requirements. Whether it can meet food hygiene requirements is the most fundamental requirement of fermentation equipment. Whether glass fiber reinforced plastic products can meet the hygiene requirements, the key to the choice of lining resin, that is, food grade resin must be used.
2) Lightweight and strong. The specific gravity of FRP is only 1.4-2.0, while the tensile strength of fiber-wound FRP can reach 300-500Mpa, which exceeds the ultimate strength of ordinary steel. If calculated according to this strength, it also meets or exceeds some special alloy steel, so it can be used as anti-corrosion. The main structural material of the equipment, and has the advantage of convenient transportation, installation and maintenance. Excellent corrosion resistance. One of the biggest features of FRP is its good corrosion resistance. Through the selection of the type and grade of the resin, a suitable molding process can be used to produce FRP products resistant to various acids, alkalis, salt oils and organic solvents.
Good surface properties and easy to clean and sterilize. Because FRP is integrally formed, it has no joints and the inner wall is smooth. When it is connected with the chemical medium, there are few corrosion products and scales on the surface, and no bacteria and microorganisms. Therefore, it does not pollute the medium and is easy to clean. After special inspection by the food and drug management department, FRP has reached the requirements of food brewing and pharmaceutical industry.
Good design. FRP is a composite material that can change its original type, quantity ratio and reinforcement material to meet different performance requirements.
6) Good construction process. The uncured resin and reinforcing material have the ability to change shape and, therefore, can be easily processed into a desired shape by different molding methods and molds. This feature is best suited for large, integral and complex equipment and construction requirements for on-site construction and assembly.
7) Anti-aging and flame retardant. FRP is a product in the category of reinforced plastics, which have problems of natural aging and burning. However, after more than 60 years of research in the world, China has been solved by more than 30 years of research. The reinforcing material is treated with a coupling agent. After 50 years of use, the bending strength can be maintained at 64-46%, and the tensile strength retention rate is 71.2%. If the anti-aging agent is added, the anti-aging performance is better; the flame retardant is added to the FRP matrix and the flame retardant resin is added to the flame retardant, and the oxygen index can reach 34-36, which fully meets the flame retardant requirements of the fermentation equipment. .
