What is magnesium oxide commonly used for in life

1. One of the main uses of magnesium oxide is as a flame retardant. Traditional flame retardant materials widely use halogen-containing polymers or flame retardant mixtures composed of halogen-containing flame retardants.
2. Another use of magnesium oxide is that it can be used as a neutralizer. Magnesium oxide is alkaline and has good adsorption performance. It can be used as a neutralizer for acid containing waste gas, waste water treatment, waste water treatment containing heavy metals and organic substances. With the improvement of environmental protection requirements, domestic demand is growing rapidly.
3. The fine magnesium oxide can be used as optical coating. When the coating thickness is between 300 nm and 7 mm, the coating is transparent. The refractive index of 1 mm thick coating is 1.72.
4. Used for climbing rocks, it can absorb sweat from hands. (Note: inhaling magnesium oxide smoke can cause metal smog disease)
5. It is mainly used to prepare oral medicine to neutralize excessive gastric acid. Commonly used preparations are: magnesium emulsion - emulsion; Magnesium cover sheet - each sheet contains 0.1g MgO,; Acid making powder - powder made of magnesium oxide and sodium bicarbonate.
6. Light magnesium oxide is mainly used as raw material for preparing ceramics, enamel, refractory crucible and refractory brick. It is also used as a polishing agent, adhesive url] coating] and paper filler, and as a promoter and activator of neoprene and fluororubber.
