Product Description:
Various ceramic fiber folding blocks are made of ceramic fiber needle punched blankets of corresponding materials and processed on special machinery according to the structure and size of fiber components. During the processing, a certain proportion of compression is maintained to ensure that after the wall lining of the ceramic fiber folding block is built, the ceramic fiber folding blocks are squeezed into a seamless whole due to the expansion of each ceramic fiber folding block in different directions.
Product category:
◎ 1050 ceramic fiber folding block rdgw-189z
◎ 1260 ceramic fiber folding block rdgw-289z
◎ high purity ceramic fiber folding block rdgw-389z
◎ high alumina ceramic fiber folding block rdgw-489z
◎ zirconium containing ceramic fiber folding block rdgw-589z
Product features:
◎ excellent chemical stability: low heat capacity and low thermal conductivity
◎ excellent thermal stability and thermal vibration resistance
◎ excellent elasticity. Since the fiber is in the pre compression state, its expansion can compensate the fiber shrinkage and improve the thermal insulation performance of the fiber furnace lining
◎ excellent heat flow erosion resistance and high mechanical strength
◎ simple and rapid installation and high safety performance
Typical applications:
Lining of various industrial furnaces and heating devices in metallurgy, machinery, building materials, petrochemical industry, nonferrous metals and other industries
