What alternative names does magnesium hydroxide have in global industrial markets?
Its natural mineral form is called Brucite, industrial alias includes Caustic Magnesia and Magnesium Hydrate. The liquid pharmaceutical suspension variant is named Milk of Magnesia, while manufacturers also call it halogen free magnesium based flame retardant for polymer processing.
Why is magnesium hydroxide superior to aluminum hydroxide as halogen free flame retardant?
It owns a thermal decomposition temperature up to 330 Celsius degrees, far higher than aluminum hydroxide. It remains stable during high temperature plastic extrusion without premature decomposition, and produces less smoke with non toxic magnesium oxide residues after combustion.
What purity grades of magnesium hydroxide can you offer for different industrial scenarios?
Water treatment and flue gas desulfurization grades range from 90 to 95 percent purity. Surface modified flame retardant powder for LSZH cables keeps purity above 98 percent. Pharmaceutical grade reaches over 99 percent, and ultra high purity electronic grade hits 99.5 percent and above.
How does magnesium hydroxide handle acid wastewater and heavy metal contaminants simultaneously?
As mild weak base, it buffers wastewater pH steadily near 9.5 without over alkalization. Its porous surface adsorbs nickel copper cadmium ions to form insoluble precipitates, lowering heavy metal content to meet industrial discharge standards.
What core merits does magnesium hydroxide have for coal boiler flue gas desulfurization projects?
It reacts fully with sulfur dioxide to secure high desulfurization efficiency. The generated magnesium sulfate byproduct can be recycled for secondary usage, and it effectively reduces tower scaling issues compared with traditional limestone desulfurizer.
What function does pharmaceutical grade magnesium hydroxide perform in fine chemical production?
It undergoes strict heavy metal and microbial control to produce gastric antacid suspensions. It also acts as key intermediate for synthesizing high purity magnesium oxide and other specialty magnesium chemical compounds.
Which industrial finished products are suitable to add surface activated magnesium hydroxide as filler?
It applies widely to low smoke zero halogen cables, PA PP PE engineering plastic parts, aluminum composite wall panels, rubber floor mats and special fire resistant printing ink for construction and electronic manufacturing industries.
What role does magnesium hydroxide play in pulp hydrogen peroxide bleaching procedures?
It serves as stable alkaline buffer to control bleaching liquid pH and protect cellulose fibers from corrosion. It cuts the consumption of bleaching agents and avoids tiny dark spot defects on finished paper surfaces.
