Boric acid research - manufacturer of boric acid crystal shape factors Appropriate chemical industry

boric acid is boron oxide hydrate, the shape of tiny crystals or white powder, soluble in water and organic matter, etc. , widely used in glass, enamel and ceramic industry, also used in metal welding, leather, photographic daily-used chemical industry, etc.

boric acid manufacturers according to the principle of the formation of crystals, probes into the factors influencing the boric acid crystal shape and size: stir type, stir speed, the influence of inorganic salt concentration and PH value.

is the crystallization of boric acid principle under the condition of the saturated, precipitation from aqueous solution, and only when the concentration reaches a certain degree of saturation is likely to crystal precipitation. Boric acid manufacturers think, in the ideal state, the crystallization of boric acid process was conducted in the interface stability. Medium size related to crystalline material nature, the stability is easily affected by environmental conditions, such as mixing, temperature or impurities, etc.

boric acid manufacturers use at type mixing slurry is beneficial to the formation of crystal type, and the spiral or flat vane impeller resistance is relatively large, unfavorable to the crystallization of boric acid.

mixing rate of speed affect the size of the grain, can avoid saturated solution, stirring rate is too small, the solution of the turbulent degree would be small, the grain size of scouring force is small, easy to produce large flake crystal; Stirring rate is too large, although can affect the size of the crystal, but it will not change shape, the energy consumption is also big, therefore, boric acid manufacturers to choose suitable stirring speed for production.

boric acid manufacturers will join in the process of production of sodium sulfate and magnesium sulfate, inorganic salt, when these inorganic salt concentration less than 20%, will contribute to the formation of granular crystal.

boric acid manufacturer after test, it is concluded that the process of producing boric acid solution of PH control in 2. 5 to 3. The most appropriate between 0.

boric acid manufacturer production of boric acid size only to the most appropriate size, just can make the downstream industry can be sustained and stable development, improve the quality of the products.
