Recently, a customer calls to consult the relevant matters of dye magnesium oxide, Meishen company will take this for you to introduce the relevant knowledge in detail.
Dye factory procurement of magnesium oxide, there are generally two uses, the treatment of production waste water is generally used 85 powder, this is not much to describe, we specifically in the production of dye with magnesium oxide what use?
Magnesium oxide used in dyes and dye intermediates, catalytic effect is significant, effective adjustment of pH concentration, used in products to improve the color light, bright color products, improve the quality of products.
Magnesium oxide in the dye mainly plays the role of filler. Some products have requirements for whiteness, but there are also heavy color products on the color of magnesium oxide requirements are not too strict.
Secondly, the content of impurities to be less, sieve residue 325 mesh 0.01. Hebei Meishen Technology Co., Ltd. has been committed to the research and development of magnesium oxide production for a long time, has mastered the production process of magnesium oxide at home and abroad, our company's magnesium oxide, is to brine or brine block solution in addition to impurity, purification, with sodium carbonate solution at room temperature reaction.
After the reaction, the crystal form of magnesium carbonate was transformed into basic magnesium carbonate in a certain temperature and time range.
The obtained basic magnesium carbonate was filtered, washed, dried under vacuum condition and then dynamically calcined and decomposed. The final product was obtained by strictly controlling the process parameters during the whole process. The product indexes were better than those of HG/T2573-2012 and HG/T3928-2012 standards.
