2. The construction speed: easy to install, roof, grid plate, floor plate with lifting welding, faster method than concrete cast more than 8 times; wall using assembly welding, five times faster than block wall above can greatly shorten the construction period. Wall paneling can be sawed, nailed, drilled, can be cut, random manufacturing building structure. 3. Good sound insulation waterproof fire performance: sound insulation up to 45dB, this sheet has a self waterproof, fire resistance of less than 2.5 hours. Anti-freeze-thaw cycles or more 25 times, moisture resistance and other test items are up to national standards. Features and Benefits 1. Fly light partition plate light: material with special cement and other inorganic materials and additives, with a slurry, lightweight partition board equipment, the air is added to the mixture, and hole lead into numerous porous, lightweight wall panels joined together honeycomb, light wall panels, so that the products become lighter than wood, can float on the water. 2. Insulation: When do the inner circle structure, without auxiliary insulation materials, thermal insulation will be able to meet the requirements of China's energy housing. 3. impermeability: internal holes are independent closed pores with a diameter of about 1-2mm, can effectively prevent moisture protection scattered.
