Application background and overview of nickel fluoroborate
Nickel fluoroborate, also called nickel tetrafluoroborate, is used in the manufacture of organic synthesis catalysts, nickel electroplating, nickel flux, etc.
Applications of Nickel Fluoborate
CN201611252774.9 provides a nickel tetrafluoroborate type aluminum magnesium carbonate nickel iron electroplating solution (g·kg-1), which is composed of the following ingredients: N-ethyl bromide Pyridine: 150~160, ammonium tetrafluoroborate: 80~90, ferric chloride: 4~6, nickel tetrafluoroborate: 40~50, acetone: 700~715, tetrafluoroboric acid: 1~3, boric acid: 1 ~3. Nickel-iron alloy has been widely used in the production of household appliances, plastic electroplated parts, construction accessories, auto parts and other products. The corrosion resistance of full-bright nickel-iron alloy coating containing sodium iron carbonate is equivalent to that of nickel coating, but its hardness is higher than that of nickel coating and its toughness is better than that of bright nickel coating. Therefore, it can be used as a protective decorative coating instead of bright nickel coating.
PTA, purified terephthalic acid, is a bulk chemical industrial raw material with relatively concentrated applications. More than 90% of the world’s PTA is used to produce polyethylene terephthalate, and the rest is used to produce polyethylene terephthalate. Produces synthetic materials such as polytrimethylene terephthalate and polybutylene terephthalate.
CN201810065815.6 provides a method for preparing differentiated PTA, which includes the following steps: (1) combining bismuth molybdate, graphene oxide, hypochlorous acid aqueous solution, zinc oxide, white carbon black, potassium titanate whiskers and Hydrofluoric acid aqueous solution is mixed and ground, and then subjected to hydrothermal reaction, filtered, calcined, plasma treated, and modified with silicone to prepare a special anti-aging agent; (2) Mix acetic acid and water and then add sodium hexametaphosphate aqueous solution , nickel fluoroborate, calcium tungstate and the special anti-aging agent obtained in step (1), beat and disperse to prepare a special modified liquid, fuse with the crude terephthalic acid slurry, crystallize, then separate the solid and liquid, wash, dry and beat. , then solid-liquid separation and then hydrogenation and refining to prepare differentiated PTA. The product prepared by the method of the invention has obvious anti-aging effect.
CN201280056930.8 reports a method of treating a metal surface to reduce corrosion thereon and improve the reflectivity of the treated surface. The method includes: (a) plating the metal surface with an electroless nickel plating solution; and then ( b) Dip silver onto the surface plated with electroless nickel, thereby substantially avoiding corrosion of the metal surface and/or substantially increasing the reflectivity of the silver plated surface. This treatment method can be used to improve the solderability of metal surfaces, for example in electronic packaging applications and in the manufacture of light-emitting diodes (LEDs). The nickel ion source can be any suitable nickel ion source, and is preferably a nickel salt selected from the group consisting of nickel bromide, nickel fluoroborate, nickel sulfonate, nickel sulfamate, nickel alkyl sulfonate, A group consisting of nickel sulfate, nickel chloride, nickel acetate, nickel hypophosphite and a combination of one or more of the aforementioned nickel salts. In a preferred embodiment, the nickel salt is nickel sulfamate. In another preferred embodiment, the nickel salt is nickel sulfate.
