Hebei Messi Biology Co., Ltd. stated that in order to overcome the defects of poor catalytic activity and poor stability of ruthenium-based ammonia decomposition hydrogen production catalysts in the prior art under medium and low temperature conditions, it provides a ruthenium-based ammonia decomposition hydrogen production catalyst for ammonia Application of decomposition to prepare carbon-free hydrogen. […]

Glass-ceramic is used in home appliance glass, induction cooker boards, and glass-ceramic casserole. Hebei Messi Biology Co., Ltd. said that adding magnesium oxide to glass-ceramic can adjust the crystallization temperature of the glass. At low temperature, it can slow down the decrease of glass viscosity, and at high temperature, it can accelerate the increase of

Tibet Mag stated that silicon steel grade magnesium oxide needs to meet the quality and technical indicators of MgO>98%, CaO<0.5%, and Cl<0.02%. The impurity CaO will be hydrated into Ca(OH)2 in the slurry and coated on the surface of the steel plate to absorb CO2 in the air to form CaCO3. Under the action of

Tibet Mag said, the production of silicon steel grade magnesium oxide is mainly based on seawater brine and minerals, etc. as raw materials. When producing with liquid raw material, we first use alkaline solution as precipitant to precipitate magnesium, and then further prepare magnesium oxide. Our country mainly adopts alkaline magnesium carbonate as intermediate brine

In 1994, the cellulose diacetate production line of Nantong Company was put into operation, and cellulose diacetate was localized for the first time. Subsequently, Nantong Company has undergone expansions one after another, and its annual production capacity of cellulose acetate has reached 200,000 tons, ranking second in the world in terms of production scale. Over

Because cellulose acetate uses renewable plant cellulose as raw material, the production process has less pollution, cellulose acetate is not easy to catch fire, and can be used to make cellulose diacetate tow for cigarettes, textiles, liquid crystal display (LCD) polarizer protective film, Film substrates, plastic products, coatings, inks, etc., have excellent performance and various
