Cement board wall Using industrial and agricultural solid waste (such as fly ash, coal gangue, quartz sand, tailings sand, rice bran, wheat straw, cotton stalk, sawdust, etc.) As raw materials, the current lightweight partition board products, foamed cement Has the lowest thermal conductivity. Cement insulation core material, while making up for the flammability, permeability, toxic and short life defects of traditional materials.
2. High strength: By adjusting the thickness of the space board and the built-in skeleton, the carrying capacity of the floor is 2.5-5.0KN/m2, and the carrying capacity of the roof is 1.0~5.0KN/m2.
3. Insulation, energy saving: wall thickness = thickness of insulation layer, while China's existing building wall energy-saving technology adopts the practice of adding insulation layer to the external wall.
5. Sound insulation: 120mm thick sound insulation coefficient: ≥45 (db), which can easily achieve more than 60 (db) by adjusting the thickness of the board, the thickness of the surface layer and the sound insulation performance.
6. Lishui: The unique cement foam core material of space board is closed-cell structure, the closed cell ratio is more than 95%, and the water absorption rate is less than 2.5%, so it has good water repellency.
7. Durability: Safe service life 50 years, no replacement is required during the same life cycle of the building.
