Discussion on the materials for mechanical seals in fluorination reactors

2021-07-06View Original

Thread Content

I would appreciate it if experts in fluorine chemistry could help answer this question: 1. What material should be used for the sealing ring in a mechanical seal for reactors that use anhydrous hydrogen fluoride and phenyl-based organic compounds? 2. Is it appropriate to use graphite as the material for the stationary and rotating rings in unpressurized sintered silicon carbide?

The material for the sealing ring is pressure-sintered silicon carbide, while the sealing ring itself is made of perfluoroether

For the sealing of fluorination reactors, the latest technology no longer uses mechanical seals. Magnetic fluid sealing, which has been adopted in recent years by many leading manufacturers of fluorinated products, features no frictional contact between moving and stationary rings, resulting in zero leakage. It does not require a sealing fluid system. Unlike traditional magnetic seals, it eliminates the problem of corrosion of lower bearings inside the tank. Magnetic fluid sealing also does not need regular maintenance or lubrication, avoids product contamination, and boasts a long service life. We are the only solution provider with successful results in the fluorine chemicals industry, as well as years of stable and proven experience in its application. We can discuss and exchange technical ideas together: WeChat: 139-01520-390

Learn about magnetic fluid sealing. Zero leakage, no sealant system required, no lubrication needed for maintenance-free operation, and long service life. Note: It is not a magnetic seal, but a magnetohydrodynamic seal.

Hydrofluoric acid-resistant anti-corrosion coating -- Zhiseng Weihua, a coating manufacturer. It can be seen that after the film-forming solution in the ZS-1033 hydrofluoric acid-resistant anti-corrosion coating is mixed with inorganic fillers and cured, the polymodified phenol-fluorine resin remains stable, does not easily lose electrons, and exhibits good resistance to swelling. Materials such as barite and graphene exhibit good chemical stability in coatings, high hardness, and even small particle sizes can enable the film-forming solution to produce a dense coating. ZS-1033 coating flake structure pigment filler ; Polarized covalent bond layered structure ; Excellent chemical and physical properties ; Inert coating system ; The potential difference that tends to equilibrium after polarization ; Excellent adhesion of chemical anchor structures ; A smooth and wear-resistant surface structure; multiple layers of protection provide excellent corrosion resistance for the equipment. ZS-1033 hydrofluoric acid-resistant anti-corrosion coating (GB/T 9274-1988): no changes after 480 hours of immersion in 5% HF at room temperature ; It provides good protection for the equipment, preventing it from being corroded by fluoride ions and hydrofluoric acid.
