1.Magnesite building material is the largest consumption field of magnesium chloride, mainly adopting Hexahydrate Magnesium Chloride MgCl2·6H_2O.
2.Reaction Principle
Mix hexahydrate magnesium chloride with lightburned magnesium oxide and water, hydration reaction takes place to form magnesium oxychloride cement. The main crystal phases are 518 phase and 318 phase, forming highstrength hardened binder after curing.
3.Main Products
Fireproof boards, lightweight partition boards, greenhouse supports, magnesite manhole covers, ventilation ducts, flues, artificial stone, magnesite packaging boxes, prefab house components.
4.Advantages
Excellent fireretardant performance
Light weight to reduce building load
High strength, good impact resistance, fast curing
Good lowtemperature resistance for outdoor application in cold areas
Easy for cutting, drilling and other processing
6.Key Raw Material Indexes
Purity of magnesium chloride: High content of sodium chloride, sulfate impurities will cause efflorescence, halogenreturning, cracking and deformation of finished products.
Moisture content: Hygroscopic caking will reduce effective content and disturb formula proportion.
Baume degree of brine solution: Adjust brine concentration according to the activity of magnesium oxide.
7.Usage Notes
Adopt hexahydrate magnesium chloride with low impurities, strictly control sodium chloride, sulfate and insoluble matter.
Adjust brine concentration according to MgO activity.
Keep moistureproof storage, avoid caking which leads to inaccurate proportioning.
