Product description：
All kinds of ceramic fiber folding blocks are made of ceramic fiber needled blankets of corresponding materials, processed on special machinery according to the structure and size of fiber components. In the processing process, a certain proportion of compression is maintained to ensure that after the ceramic fiber folding block is built, due to the expansion of each ceramic fiber folding block in different directions, the ceramic fiber folding block is squeezed into a seamless whole.
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 aluminum ceramic fiber folding block RDGW-489Z
◎ Folding block containing zirconium ceramic fiber RDGW-589Z
Product features:
◎ Excellent chemical stability: low thermal capacity, low thermal conductivity
◎ Excellent thermal stability and thermal shock resistance
◎ Excellent elasticity, because the fiber is in a pre-compressed state, its expansion can compensate the fiber contraction, improve the insulation performance of the fiber lining
◎ Excellent heat flow resistance and high mechanical strength
◎ Easy and rapid installation, high safety performance
Typical applications:
All kinds of industrial furnaces and heating devices lining in metallurgy, machinery, building materials, petrochemical, non-ferrous metals and other industries.
