Feng Chun Trade is a business raw magnesite (magnesium chloride, magnesium oxide, magnesium chloride consumption, seven water magnesium, silicon rubber mold, etc.), magnesite products, edible supply magnesium chloride, magnesium chloride, and magnesium chloride production and trading company, long-term distribution of magnesium chloride prices, industrial magnesium chloride prices. Tianjin Magnesium sulfate heptahydrate brand aloe production methods: (1) sea salt production was bittern law. Sea salt production bittern obtained after evaporation method with Brine magnesium chloride hexahydrate, output high temperature salt, consisting of MgSO4 greater than 30%, NaCL less than 35%, MgCL2 about 7%, KCL about 0.5%. Dry brine solution available MgCL2 200g / L at 48 ℃ leaching, NaCL dissolve less and MgSO4 dissolve more. After separation, the immersion cooling to 10 ℃ then precipitated crude MgSO4 · 7H20 aloe brand magnesium chloride, the secondary recrystallization finished. (2) sulfuric acid method. In the first tank magnesite and slowly add water and liquor, and then neutralized with sulfuric acid, the color from white to red till the soil, control PH = 5, the relative density of 1.37-1.38) 39-40Bé). Filtered at 80 ℃ and in liquid, and then adjust the PH to 4, adding the right amount of seed with sulfuric acid, and cooled to 30 ℃ crystallization. After separation at 50-55 ℃ drying products, liquor and return to the pot. Low concentration sulfuric acid can also be used with magnesium oxide content of 65% magnesite neutralization reaction, filtration, precipitation, concentration, crystallization, centrifugation, dried magnesium chloride, magnesium sulfate heptahydrate was prepared.
