Used in commercial space, general use of 600x600 specifications, there are clear bone and dark bone of the points. Keel often aluminum or iron. The main plate can be divided into gypsum board, calcium Silicate board and Mineral wool Board three categories. Gypsum in the preceding has been explained, below we talk about Calcium silicate board and mineral Wool board.
1 The full name of the calcium silicate board is the fiber reinforced silica calcium board, it is composed of silica material (diatomite, bentonite, quartz powder, etc.), calcareous materials, reinforced fiber, etc. as the main raw material, through the pulping, forming, steaming, surface sanding and other processes made of light sheet. Calcium Silicate plate with light weight, high strength, moisture-proof, anti-corrosion, fire, another notable feature is that it is easy to process, not like gypsum board to process easily powdery fragmentation.
2 Mineral Wool Board from slag through high-temperature, high-pressure, high-speed rotation, removal of impurities, washing become mineral wool, mineral wool board mainly by mineral wool, adhesives, pulp, perlite composition. The Mineral Wool board has the similar characteristic of the calcium silicate board, but the sound absorbing performance is more advantageous than the gypsum board and the calcium Silicate board.
