Production method
1. Borax method Add water to borax, heat and dissolve in a dissolution tank, filter to remove insoluble matter, dilute to a relative density of 5.5 ° Bé, control the temperature at about 49 ℃, send it to the reactor, and then gradually add a relative density of about 11 ° Bé(75~80 ℃) Lead acetate solution (made of lead oxide and acetic acid), fully stirred during the feeding process, the reaction produces lead metaborate precipitation. After being diluted with water, clarified and rinsed for three times, the filter cake is baked at 80 ℃ until the water content is below 3%, and crushed to the required fineness to produce lead metaborate finished product.
2. after sieving lead oxide by boric acid method, dilute nitric acid is added and stirred to dissolve and react to produce lead nitrate. Filter to remove slag, add ammonia water to adjust the pH to 8 to generate lead hydroxide precipitate. After the precipitate is washed with water, it is added to a reactor containing boric acid solution, and an appropriate amount of glycerol is added to make lead hydroxide and boric acid under stirring. Fully react to generate lead metaborate, which is separated by pressure filtration, dried, crushed, and prepared as a finished product of lead metaborate.
