T/GBMEA 01-2024 Active

Main technical content: The foam agent is prepared into foam by physical methods, and then the foam is added to the slurry made of gelling materials, water, additives, etc. After mixing and stirring, it is cast into shape and cured to form a lightweight partition wallboard. Its strength is generally 0.3~1Mpa, and the density is 500~700kg/m3. Due to its porous and lightweight characteristics, it has good thermal insulation (heat transfer coefficient is 0.08~0.3W/m·K, and the thermal resistance is 20~30 times that of ordinary concrete), sound insulation, and sound absorption (the sound absorption capacity is 0.09%~0.19%, which is 8 times that of ordinary concrete). It is non-flammable and widely used in building thermal insulation materials. Especially in today's energy-saving buildings that are being widely promoted, this process is safe and non-flammable, with a fire resistance rating of more than 2h, and will gradually replace current organic thermal insulation materials such as polystyrene. It can be used in buildings with a durability of more than 50 years.
