The production process of the review - boric acid manufacturer Appropriate chemical industry

boric acid in glass, enamel, chemical and other industries has a very important role, at present our country main manufacturer of boric acid boric acid production process of acid and ammonia method, also can be divided into borax sulfuric acid neutralization, specific carbon ammonia method and sulphuric acid step method.

boric acid manufacturer with borax sulfuric acid neutralization, also called two-step, need borax was first, and then add in sulfuric acid neutralization, after crystallization centrifugal get boric acid. This method is simple in equipment, easy to master and control of technical conditions, mature technology, but this method is called two-step method, because the borax also calculate step, the actual process really long, utilization of boron is low. Manufacturer of boric acid boric acid using this method, the economic benefits of borax mainly depend on the price.

there are a handful of boric acid manufacturer in the market now, carbon ammonia method is the roasting of boron ore powder under the action of ammonium bicarbonate, ammonium borate, and then through decomposition of boric acid. Less what we need in the production process of acid and alkali, ammonia can be recycled, save resources, but the process is complex, large energy consumption, in the actual production, can also lead to the problem of poor quality.

the so-called sulfate step method is directly from the primary method of preparing boric acid boric magnesium ore, this method is simple, mature technology by-product magnesium sulfate also can be used in production. But along with our country high grade of boron ore production decreases, this method is more and more limited. And this method can produce hydrogen sulfide, caused certain environmental pollution, many current boric acid manufacturer has changed the production direction.

now, some manufacturers began to adopt more boric acid sodium borate method to produce boric acid, the method in theory is suitable for China's national conditions, but also need to further improve and rectification.
