white crystals. Usually contains 2, 4 and 6 water of crystallization. The relative density was 2. 120. Soluble in water and alcohol. Water of crystallization was lost at 60 °c. Hydrate-like ammoniacal compounds can be formed. This complex is heat-labile and easily decomposes reversibly to metal fluorides, ammonia, ammonium fluoroborate, and boron ammoniumfluoride. Deliquescence. Toxic.
fluoroboric acid zinc carbonate method: boric acid and hydrofluoric acid reaction to produce fluoroboric acid, and then with zinc carbonate reaction, control the pH value of 3~4. The impurities were removed by filtration, and the solution was evaporated under reduced pressure (60-70 ° C.) to precipitate crystals, and then dried to obtain a finished zinc fluoroborate product.
used as a catalyst for resin curing agent, fabric Resin finishing and synthetic resin production in wash-and wear-resistant textiles. It can also be used as a flame retardant, insecticide, welding material, plating solution and cobalt bonding agent.
toxic products. Hazard code: GB 6.1 class 61515 refer to fluoroboric acid. Packed in polyethylene plastic barrels with a net weight of 4kg per barrel, one carton or wooden case per four barrels. The package should be marked with "drug. Store in a cool, ventilated, dry warehouse. Prevent rain and moisture. The packaging should be sealed. Attention should be paid to prevent package breakage during loading and unloading.
