Ceramic fiber board is a kind of wood board, which is interwoven with lignocellulose fibers and utilizes its inherent adhesive properties. If it is deformed due to improper operation and use, it will not only affect its use effect, but also greatly reduce its aesthetics. So be careful when using it. Now, let's take a look at how to avoid the deformation of ceramic fiber board.
1. Reduce the moisture content of ceramic fiber board and make it uniform, thus reducing its weight.
2. Stack horizontally and press heavy objects after hot pressing. The direction of aluminum silicate fiber board fiber is parallel to the direction of dry shrinkage and small expansion of substrate.
4. When sticking the aluminum silicate fiber board, the middle part is slightly loose.
5. When producing this product, reduce the amount of urea-formaldehyde resin glue, make the glue layer soft, and improve the hot pressing conditions.
Blowing fiber (short, thin, easy to break and mix) is used as the raw material of ceramic fiber board, and a certain proportion of binder and filler-grade auxiliary agent are added, which are fully dispersed into slurry in the slurry mixing tank after beating. Pumped into the forming pool, stirred with compressed air. The mold is put into the forming pool, and the fiber slurry is adsorbed on the mold by the principle of vacuumizing. Accurate control of adsorption time, vacuum dehydration of wet fiber materials, demoulding, placing on a tray, and drying in a drying furnace for 10-24 hours. After the fiberboard is dried, it passes through a special grinder and edge trimmer, and its size is accurately controlled.
In addition to the excellent properties corresponding to the loose ceramic fiber cotton, ceramic fiber board also has hard texture, excellent toughness and strength, and excellent wind erosion resistance. It is an ideal energy-saving material for thermal insulation, kilns, pipelines and other equipment, and it is non-expansive when heated, light in weight, convenient for construction, and can be cut and bent at will.
Ceramic fiber board has high compressive strength and long service life. Low heat capacity and low thermal conductivity. Good toughness and non-brittle material. Accurate size, good flatness, easy cutting and installation, convenient construction, excellent wind erosion resistance, continuous production, uniform fiber distribution and stable performance.
