It is magnesia cement.In many enterprises, people according to it with two kinds of magnesium compounds of magnesia and magnesium chloride be main
The characteristics of raw material, double magnesium cement are simply referred to as again.Magnesium cement be with the light burnt powder obtained by calcined magnesite stone or
Ashes (main component is MgO) obtained by low temperature calcination dolomite is cementing agent, with magnesium chloride hexahydrate
(MgCl2·6H2) etc. O water-soluble magnesium salt is blender, adds water, the light-burning magnesium powder and six water for being formed
Magnesium chloride as primary raw material, therefore, then generally, magnesium cement refers to just magnesia oxychloride cement.
The hardenite main component that magnesium cement is formed is 5Mg (OH)2·MgCl2·8H2O and
3Mg(OH)2·MgCl2·8H2Magnesia-magnesium chloride that O crystalline phases are constituted-water ternary compound crystalline phase double salt,
In addition, some Mg (OH)2Gel.Magnesium cement can be hardened quickly at normal temperatures and pressures, shape
Into the fragility artificial stone very higher than larger and hardness.Using its this hardening gelling, can be processed into
Various construction materials and ornament materials, have broad application prospects.At present, architectural engineering it
In the magnesium cement generally used all mainly with magnesia and magnesium chloride as main material is prepared from, but
It is that this cement can corrode metal in the halogen that gets damp, surface is easily caused for secondary decoration and is come off,
And this cement water resistance is very poor, and the life-span is shorter.Therefore to magnesia and magnesium chloride as main material system
Standby magnesia oxychloride cement is improved, to adapt to requirement of the modern construction engineering for magnesium cement.
