Magnesium oxide’s production technology
There are a lot of magnesium oxide manufacturers all over the world. Due to the speed of magnesium oxide industry’s development is very fast, the improved speed in production technology is also fast. Generally specking, there are two methods, dolomite by carbonization and brine method. However, many small manufacturers don’t know about these two. Therefore, let’s talk about the production technology of dolomite by carbonization and brine method. The dolomite by carbonization is a new method to produce magnesium carbonate through carbonation and using dolomite as raw material. It can improve the use ratio of magnesium oxide in dolomite, and reduce the consumption of carbon dioxide. At same time, the calcium in dolomite can be used fully. According to the different raw material, brine method adjusts its’ concentration in reaction liquid. It controls the reaction temperature about 40℃ to 50℃, and the response time is about 3 to 5 hours. In this way, the semi-finished magnesium carbonate has uniform particle and a smooth surface. 1.The high active magnesium oxide produced by dolomite carbonization has a higher activity and stronger adsorbing ability than brine method produced. It also has a strong coking resistance in using in rubber. At the same time, it has obvious effect in slowing the degradation of rubber vulcanization. 1、The magnesium oxide produced by dolomite carbonization has a larger apparent specific volume than brine method produced, it is more than twice over the brine method produced. Magnesium oxide with high apparent specific volume has a good mobility and high dispersing performance. It also has a stronger oxidation resistance, stretch ability and surge withstand capability. Through the comparative analysis of the above, we all know that dolomite carbonization has a better performance than brine method in producing magnesium oxide, therefore, it requires many small manufacturer should update production technology as soon as possible. Only in this way can meet the more needs of magnesium oxide market.
