The reaction process of magnesium oxide during high-temperature annealing of grain-oriented silicon steel

Hebei Messi Biology Co., Ltd. stated that it used salt lake brine to prepare silicon steel grade magnesium oxide. It used X-ray diffractometer, laser particle size analyzer, high and low vacuum scanning electron microscope and other analytical instruments to investigate the calcination of brine magnesium precipitation and calcination process to prepare silicon steel grade magnesium oxide. During the process, the calcination temperature and calcination time affect the activity, morphology and particle size of magnesium oxide. The results show that as the calcination temperature increases and the calcination time prolongs, the activity of magnesium oxide gradually decreases; as the calcination…

Study on the preparation of spherical nano magnesium oxide agglomerated powder

Hebei Messi Biology Co., Ltd. stated that magnesium oxide is a typical alkaline earth metal oxide, which is widely used in industry, medicine, food and other fields. Nano-magnesium oxide has surface effect, volume effect, etc. Its performance is superior to ordinary magnesium oxide and can be used in new fields such as electronic ceramics and catalysts. However, nano magnesium oxide is easy to agglomerate and its morphology is difficult to control, which limits its application. Spherical nano-magnesium oxide agglomerated powder has the advantages of large specific surface area and uniform particle size distribution. Therefore, it has high reactivity, strong…

Properties and applications of magnesium oxide for leather tanning

Hebei Messi Biology Co., Ltd. says that since the development of a suitable chrome tanning process for leather in 1858, about half of the publications on tanning chemistry and tanning technology have been devoted to the improvement of chromium utilization. There are four main methods, i.e. control of pH, selection of masking agent, control of time and temperature, and control of liquor pH control, not only by adding more neutralizing agents to raise the pH in the later stages of tanning, but also by incorporating more modern techniques such as the addition of magnesium oxide, a crystalline soluble alkalinizing…

Application of magnesium hydroxide in glass fiber composite materials

Hebei Messi Biology Co., Ltd. stated that compared with aluminum hydroxide, the flame retardant and smoke elimination mechanisms of active magnesium hydroxide are very similar to those of aluminum hydroxide, but active magnesium hydroxide has many outstanding advantages that aluminum hydroxide does not have. First of all, the decomposition temperature of magnesium hydroxide is relatively high, and it does not start to decompose into water and magnesium oxide until it is heated to 340°C. It not only has a good flame retardant effect, but can also meet the market’s demand for flame-retardant FRP with higher temperature resistance. Secondly, the…

Application of magnesium oxide in ammonia nitrogen wastewater treatment

One of the main influencing factors of eutrophication of rivers and lakes is ammonia nitrogen pollution. At present, my country’s annual output of synthetic urea and ammonia is more than 40 million tons. The production of various ammonia nitrogen products causes enterprises to discharge large amounts of ammonia nitrogen wastewater. At the same time, nature produces ammonia nitrogen wastewater during the process of garbage fermentation. The total amount exceeds hundreds of millions of tons every year, which has a great impact on the natural environment. The mechanism of magnesium oxide treating ammonia nitrogen wastewater Magnesium oxide is a metal…
