Product Description:
◎ various ceramic fiber modules 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 module is built, due to the expansion of each ceramic fiber module in different directions, the ceramic fiber modules are squeezed into a seamless whole. The ceramic fiber modules can be directly fixed on the steel plate of the industrial kiln shell through various forms of anchors.
Product features:
◎ excellent chemical stability
◎ the application of ceramic fiber module is not only used in kilns, but also brings the following benefits to end users:
◎ various forms of anchors on the back of the module make the installation of the module adopt either parallel arrangement or parquet floor arrangement.
◎ the folded blankets will squeeze each other in different directions without gaps after being unbound.
◎ elastic fiber blanket can resist external mechanical forces.
◎ the elasticity of fiber blanket can make up for the deformation of furnace shell, so that there will be no gap between components.
◎ due to its light weight, it has little heat absorption when used as thermal insulation material.
◎ low thermal conductivity brings high energy-saving effect.
◎ have the ability to resist any thermal shock.
◎ the lining body does not need drying and curing, and can be put into use immediately after installation.
◎ the anchor system is far away from the hot surface of the component, so that the metal anchor is at a relatively low temperature, which improves the safety of the anchor.
