Ceramic fiber folding block-Ceramic fiber_polycrystalline series_Shandong Hengze Energy Saving Technology Co., Ltd.

Ceramic fiber folding block

Various ceramic fiber folding blocks are made of ceramic fiber acupuncture blankets of corresponding materials, and are processed on special machinery according to the structure and size of fiber components. In the process of processing, a certain proportion of compression is maintained to ensure that after the lining of the ceramic fiber folded blocks is completed, due to the expansion of each ceramic fiber folded block in different directions, the ceramic fiber folded blocks are extruded into a seamless shape. the whole of the gap.
