<p>Therefore, the product is widely used as a firewall. 5, noise performance According to the wall thickness and surface treatment methods can be noise 40-50 dB. It is also a good sound absorbing material. As a result of adding air, greatly improving the sound insulation products. 6, high strength products on both sides of the paste with high-strength fiber mesh, and then add the anti-corrosion staple fiber skeleton, </p>
<p>the slurry hardening and mesh and fiber coagulation as one, greatly enhancing the cement's flexural and impact properties. The ASTRI test are in line with the national building materials JC660-1997 industry standards. 7, convenient construction Because it is porous, coupled with the product nails, can plane, can drill and other general machining, so the water, electricity pipeline installation and embedding </p>
<p>construction than all the wall panels are convenient. Compared with the installation of small blocks of wet solid workings of clay solid bricks and hollow bricks, the construction progress of wallboards is 30 times different, which can greatly shorten the construction period. Strong board surface can be directly paint or paint. After painting can paste a variety of wallpaper. 8, the economy from the design on the </p>
