Manufacture standard:GB25970-2010<inorganic non-combustible composite boar t;

Product introduction:

Xinlong inorganic non-combustible composite board is made of magnesium oxide, magnesium chloride, middle alkali glass fiber mesh, expanded perlite, sawdust, and other auxiliary materials and additives,which is advanced process,demould, conservation,anti-halogen processing and drying processes.what’s more it is popular in the world.It is divided into building materials board and fire resistance board according to processes, formulas. Its technical indicators are completely compliance with the requirements of GB 25970-2010<inorganic non-combustible composite boar t; standard.

Main features:

1.fireproof, non-combustible.Class A1 non-combustible sheet.
2.Waterproof, moisture-proof, anti-corrosion, acid and alkali resistance.
3.Heat insulation, and sound insulation.
4.Low shrinkage rate, light weight, and high strength, overall low density.
5.Smooth surface, can be painted, pasted tile, pasted wallpaper and other decorative materials.
6.Excellent fire resistance performance.Using 12mm thickness plate can be made partition,it can reach 4 hours of fire resistance.
7.Construction cost of low, and can be cut, saw,nail,and bent.

Main application areas:

1.Fire resistance board series:used in the tunnel ceiling, steel structure column, beam,horizontal floor, fire partition wall, and room dividers.
2.Decorative board series:used in the hotels, office building, residential renovation.
3.Substrate board series:used in ceiling, partition, fireproof door core,warehouse board and lining board.
4.Sound-absorption board series:used in the subways,bus stations, theaters, factories, and other public building.

The surface density of magnesium oxide board is 0.8-1.2g/cm3.It is reduced the building loading,and made the building weight of interior wall reduce 60% more,meanwhile,increased the used area about 5-8%.Light weight board benefit to the structure anti-vibration,and efficiently decrease the cost of groundwork and struct body. 

Selection the magnesium oxide board should be notice that:

1.Healthy and Eco-friendly:must not has the asbestos and etc harmful substance materials.
2.Chloride content rate: the ratio must not more than 10%.
3.Deformation:raw material,process technology, and the period of production should be very well.
4.Physical performance:anti-bending strength,anti-impact,and nail holding should be very well.
5.Board surface:image should excellent.
6.Thickness deviation:when the board diagonal line greater than 2000mm,board length and width deviation should more or less 5mm; when the board diagonal lin less than 2000mm, board length and width deviation should more or less 3mm.
7.Shrinkage rate:dry shrinkage rate should less than 0.3% and the wet expansion rate should less than 0.6%.
8.Anti-halogen performance:should no water,no damp.
9.Using time:great duration of life.
