MGOWall Board Machine Required Raw MaterialMagnesium Oxide Wall board is made of sawdust or straw (rice hulls), or any kind of crop straw and inorganic material (such as talcum powder and powder coal ash) after special technology. So this project has low production cost, small investment and fast effectiveness.Wall Board Performance 1 Air-dry density ≤ (Standard index)50kg/m2 (Test Value) 30.0kg/ m2 2 Drying shrinkage rate of the board ≤0.08% 0.015% 3 Anti-breaking load ≥1400N 5640N 4 Anti-impact No breakage phenomenon such as cracking after three impacts No breakage phenomenon such as cracking after three impacts 5 Thermal resistance of main section T=90mm ≥1.35m2.k/w ≥1.36m2.k/w 6 Thermal bridges area ratio ≤8% 2.22% 7 Sound reduction Index 36dB 8 Radioactivity None
