Polyethylene (PE) is a thermoplastic resin obtained by polymerization of monomer ethylene, with good cold resistance, good mechanical strength, dielectric properties, widely used in cables, films, pipes, packaging, containers, medical appliances and other products. However, PE has an oxygen index of 17.4%, which is a flammable material. PE materials burn quickly, generate heat/smoke, and melt […]

The change of refractive index of magnesium oxide with uniaxial and biaxial pressurization was calculated by using the first nature principle, and it was found that the dielectric constant decreased by pressurization, and the biaxial pressurization changed magnesium oxide from negative uniaxial crystal to positive uniaxial crystal. Magnesium oxide has many excellent properties, such as

The article reports a facile method to prepare a novel 3D flexible multifunctional nitrogen-doped carbon nanotube electrode. The carbon nanotubes were simultaneously modified by MgO nanosheets. The researchers prepared CF@CNTs/MgO complexes by using a facile liquid-phase impregnation/adsorption method in combination with the pyrolysis of commercially available inexpensive melamine foam (MF). This method allows for efficient

Magnesium oxide is known as a green and safe wastewater treatment agent, this paper reviews the research and application progress of magnesium hydroxide in environmental protection, including the removal of heavy metal ions such as lead, chromium and nickel in industrial wastewater and the neutralization treatment of acidic wastewater, and lists the good treatment effect

Magnesium oxide nano powders were prepared by precipitation method using anhydrous sodium carbonate and magnesium chloride hexahydrate as raw materials, and the influence of chloride ions in the synthesis of the powders was investigated. It was shown that the precipitation process with the addition of chloride ions could change the phase composition of the precursors,

The high-performance requirements of special cements put forward more stringent control targets for production process conditions, raw material selection, process quality monitoring, testing methods and other aspects. In view of the individual technical needs of the project, the control range of special cement indexes can be adjusted appropriately to provide better control. Take magnesium oxide

Modified magnesium hydroxide nanoparticles with 98% yield were synthesized by an easy-to-industrialize liquid-phase precipitation method with the synergistic effect of sodium dodecyl sulfate (SDS) and sodium polyacrylate (PA-Na) compound modifiers. The optimum amount of modifier was determined by the settling volume experiment to be 0.2% (mass fraction of the compound modifier to the synthesized sample),

The present invention discloses the method of producing alkaline magnesium carbonate. Crude hydrazine preparation step, from the reaction of urea liquid and sodium hypochlorite in the reactor to produce hydrazine hydrate, the temperature of crude hydrazine in the reactor at 100 degrees -110 degrees, the by-products include sodium chloride and sodium carbonate; distillation step, without

The pollution caused by the emission of sulfur dioxide and nitrogen oxides in China is becoming more and more serious, and the national efforts to control air pollution are gradually increasing. It is necessary and urgent to research and develop economic, efficient and simple flue gas desulfurization and denitrification technology. The chemically prepared magnesium oxide

Magnesia ceramic is a typical new type of ceramic and also a traditional refractory. Magnesium oxide itself has strong corrosion resistance to alkaline metal solutions. The prepared magnesium oxide ceramic crucible has excellent chemical properties and stability against metal corrosion, and has no effect on magnesium, nickel, uranium, aluminum, molybdenum, etc. Magnesium oxide ceramics can
