Magnesium oxysulfide boards are produced by adding calcium sulfate or a mixture of calcium sulfate and calcium phosphate to magnesium chloride solution.
Performance characteristics of magnesium oxysulfide fireproof boards:They are air-hardening cementitious materials, featuring a setting and hardening mechanism different from that of ordinary silicate cement. After curing, magnesium oxysulfide boards become more stable in drier ambient air. With low alkalinity and low corrosivity, the pH value of the slurry filtrate ranges from 8 to 9.5, nearly neutral, resulting in minimal corrosion to glass fibers and wood fibers. The product also boasts light weight and low density.
