Release date:2017-11-22 Author: Click:

Borax process process of monomer boron manufacturers to explain the following:

1. Pressure alkali solution: the pretreated boron and magnesium mineral powder is mixed with sodium hydroxide solution, and the sodium borate solution is decomposed with temperature and pressure, and then the borax is obtained by carbonization treatment.

2MgO.B2O3+2NaOH+H2O - 2NaBO2+2Mg (OH) 2

4 NaBO2+CO2 - Na2B4O7+Na2CO3

2, carbon alkali method: the pretreatment of boron magnesium ore powder and sodium carbonate solution mixed heating, through carbon dioxide pressure rise after reaction borax.

2 (2MgO.B2O3) +Na2CO3+2CO2+xH2O to Na2B4O7+4MgO.3CO2. xH2O

3, soda solution (salt brine): salt brine after treatment with borax paste, soda mixed cooking is borax.

CaB4O7+ Na2CO3 to Na2B4O7+ CaCO3

4H3BO3+ Na2CO3 to Na2B4O7+6H2O+CO2

4, soda alkali solution (sodium borite): soda ash and sodium bicarbonate decomposed pretreated sodium borosilicate, adding caustic starch to settle and crystallize borax.

2 (NaO.2CaO.5B2O3.16H2O) + Na2CO3+ NaHCO3 > 5Na2B4O7+4CaCO3+CO2+34H2O
