Exploring the Production Process of Calcium Silicate Board

Calcium silicate board is a lightweight building board made of siliceous materials, calcareous materials and reinforcing fibers as the main raw materials, through pulping, molding, autoclaving and curing processes. It has the characteristics of fireproof, moisture-proof, soundproof, high strength, etc., and is widely used in walls, ceilings, floors and other fields. The following is a detailed analysis of its production process: 1. Core raw materials Siliceous materials Quartz sand (silicon dioxide content ≥90%): provides silicon source, enhances the high temperature resistance and chemical stability of the board. Fly ash (industrial waste recycling): reduces costs and improves environmental protection. Calcium materials Limestone (calcium oxide ≥85%): reacts with siliceous materials to generate hydrated calcium silicate (C-S-H gel) to form board strength. Cement (Silicate cement): auxiliary calcium source, accelerates the reaction process. Reinforced fiber Wood fiber: improves the flexibility and crack resistance of the board. Glass fiber/cellulose fiber: enhance tensile strength and prevent shrinkage and deformation. Additives Water reducer: improve slurry fluidity and reduce water consumption. Foaming agent (such as aluminum powder): introduce pores when manufacturing low-density boards to reduce weight. 2. Production process Raw material pretreatment and batching Crushing and grinding: Quartz sand and limestone are crushed by crusher to a particle...

Calcium silicate board: a new ecological material for building green buildings

As a model of new environmentally friendly building materials in the 21st century, calcium silicate board is made of high-purity quartz sand, high-quality cement and natural plant fiber as the main raw materials, and is refined through advanced high-temperature and high-pressure steam curing technology. This innovative composite material not only fully retains the lightweight and easy-to-install characteristics of traditional gypsum board, but also achieves multiple performance breakthroughs through molecular structure optimization: Excellent fire resistance: tested by the National Fireproof Building Materials Quality Supervision and Inspection Center, its fire resistance limit is more than 4 hours (GB/T 9978 standard), and its combustion performance reaches the A1 non-combustible standard, and it does not release toxic gases when exposed to fire; Excellent moisture-proof performance: using nano-level hydrophobic treatment technology, water absorption rate ≤8% (GB/T 7019 standard), and still maintains structural stability in a 95%RH humidity environment; Excellent durability: flexural strength ≥10MPa (GB/T 19631 standard), weathering test shows that the service life can reach more than 50 years; Green environmental protection certification: passed the LEED green building materials certification, formaldehyde emission ≤0.1mg/L (E0 standard), and radioactivity indicators meet the environmental protection requirements of GB 6566-2010. With its unique material properties, calcium silicate board has...
