Uses and synthesis methods of 1,1-difluoroethylene (vinylidene fluoride); Chemical properties: It is a flammable gas with a slight ether-like odor and is colorless. Freezing point: -144°C, boiling point: -85.7°C, melting point: -144.1°C, relative density: 1.001 (-45.3/4°C), liquid relative density: 0.617. Soluble in ethanol and ether, slightly soluble in water. The critical temperature is 30.1°C, the critical pressure is 4.29 MPa, and the critical density is 0.417 g/cm3. The flammability limit in air is 5.5%-21.3%. Uses: 1,1-difluoroethylene is primarily used to produce polyvinylidene fluoride. It is polymerized in a polymerization reactor using water as the medium, potassium persulfate as an initiator, along with a buffer; the temperature ranges from 50 to 95°C and the pressure is around 3 MPa. The resulting powdered polymer is then washed and dried to yield the final product. This is a fluoroplastic product with high mechanical strength, which can be molded using conventional thermoplastic processing methods. It possesses excellent weather resistance, chemical stability, and heat resistance, and can be used as linings and anti-corrosion diaphragms for chemical industry pipes, fittings, valves, pumps, and tanks, as well as for seals, gears, bearings, and other components in chemical machinery. It also has many important applications in the electronics and electrical industry. It is also used as a specialty solvent.

Hydrofluoric acid-resistant anti-corrosion coating 1033, Zhi Sheng Wei Hua – coating production and sales. After the film-forming solution in 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 corrosion by fluoride ions and hydrofluoric acid.
