Ceramic fiber board is an aluminum silicate fiber board, a board made of refractory material. It maintains good mechanical strength even after heating. This product is a fiber insulation product that is more rigid and has support strength than fiber blankets and felts. The main raw materials are coke and alumina powder. Blowing fiber (short fiber, thin, easy to break and mix) is used as the raw material of ceramic fiber board. A certain proportion of binder and filler-level additives are added. After being beaten by a beater, it is fully dispersed into a slurry in the mixing tank. Pump into the molding tank and stir with compressed air. Put the mold into the molding tank and use the principle of vacuum to make the fiber slurry adsorb on the mold. Precisely control the adsorption time, vacuum dewater the fiber wet material, release the mold, put it in a tray and send it to a drying furnace for drying for 10-24 hours. The dried fiberboard is precisely controlled in size by a special grinding machine and trimming machine.
In addition to the excellent performance of the ceramic fiber cotton corresponding to the loose ceramic fiber, the product has a hard texture, excellent toughness and strength, and excellent resistance to wind erosion. Non-swelling heating, light weight, convenient construction, can be cut and bent arbitrarily, it is an ideal energy-saving material for kiln, pipeline and other insulation equipment. 1.High compressive strength and long service life; 2. Low thermal capacity and low thermal conductivity; 3. Non-brittle material, good toughness; 4, accurate size, good flatness; 5, easy to cut and install, convenient construction; 6, excellent wind erosion resistance; 7. Continuous production, uniform fiber distribution and stable performance.
1. Backing insulation of kiln in cement and other building materials industries; 2. Kiln backing insulation in petrochemical, metallurgy, ceramics, and glass industries; 3. Backing insulation of heat treatment furnace; 4. Non-ferrous metal industry backing insulation; 5, high temperature reaction, heating equipment backing insulation
