Application of synthetic materials valves

Synthetic valves, which outperform metal valves in many aggressive conditions, are primarily corrosion resistant, followed by net weight, and their strength depends on the shape, alignment and number of reinforcing fibers. (In general, the greater the percentage of fiber, the greater the strength of the composite.) In valve applications, the weight content of the fibers ranges from 30% to 40% by weight, whereas the chemical stability is primarily due to the potting of the final product Fiber resin properties of the body decided. In synthetic valves, the solid polymer body can be either a thermoplastic such as PVC-PVDF, PPS-PPS, or a thermosetting resin such as polyester, ethylene and epoxy Wait). Thermosetting resins retain their strength at elevated temperatures compared to thermoplastics (ie thermosetting resins have a higher heat distortion temperature). (Note: The determination of the heat resistance of synthetic materials is referred to as heat distortion temperature under service conditions.); Currently, the most commonly used synthetic materials for chemical process valves are vinyl epoxies (thermoplastics) , Whose reinforcing fibers are shredded glass fibers (¼ inch long) and shredded graphite fibers (¼ inch long). The table below compares the performance of most widely used synthetic materials with that of corrosion resistant metals.

Due to its corrosion resistance, high strength and light weight, synthetic valves make it an economical alternative valve product for many metal or fiberglass reinforced plastic piping systems in corrosive service. In the chemical process conditions, excellent prospects for the use of synthetic valves. In the valve industry, the use of organic and synthetic materials is no longer the concept of traditional metal and non-metal valve materials. Ceramic (the valve temperature can be increased from 400 ℃ to 1200 ℃ above), plastic (with anti-corrosion characteristics), synthetic materials (corrosion resistance, light weight, high strength characteristics), memory alloy Memory alloy or temperature memory alloy reversibility and high elasticity to create the valve) and so on. New materials, is developing a large number of high-performance valve with new products. The development of new technologies, so that a variety of engineering materials used in valve manufacturing has become possible.

Organic Salt

Organic salts are organic acids, or salts formed by the reaction of organic bases with other acids and bases , which can be organic or inorganic. Such as sodium acetate (Organic Acid, Inorganic Alkali salt), tetrabutylammonium bromide (Inorganic Acid, organic base), pyridine acetate salt (organic acid, organic base), methyl sodium (alkyl salt), sodium ethanol (strong base).

Inorganic salts are salts produced by the neutralization reaction of inorganic acids and alkalis, which are called inorganic salts. Inorganic salts refer to salts that do not contain carbon elements, and organic salts refer to salts that contain carbon elements, but do not include carbonates. Organic salts are salts produced by the neutralization reaction of organic acids and alkalis, which are called organic salts. The biggest difference between inorganic and organic salts is the difference in the acids that make up them. For example, inorganic salts generally have strong hydrophilicity, while organic salts have affinity with some non-polar reagents.
