Aluminum silicate ceramic fiber module is a common fireproof material for thermal insulation construction of industrial kilns. It has excellent fireproof and thermal insulation performance. How can we judge whether the quality of aluminum silicate ceramic fiber module we buy is excellent? Please see the following:
High quality aluminum silicate ceramic fiber module includes folding block, slicing block, Palo block and vacuum forming block. Due to the different manufacturing methods and crystal structure of polycrystalline mullite fiber, its fiber length is short and its softness is poor. It can not be made into large modules, resulting in the large-scale application of polycrystalline fibers. At present, polycrystalline fiber is mostly used on the inner surface of castable or refractory brick furnace wall and furnace top. The use of polycrystalline fiber paste can effectively reduce the temperature of furnace outer wall and reduce the heat storage loss of furnace wall.
At present, most of the aluminum silicate ceramic fiber modules used in China are folding blocks. The structure uses needle punched blankets for folding, and mechanical equipment is used to preload the modules during forming. The surface is uneven due to the manufacturing method of folding block, which affects the spraying effect of anti erosion coating. The slicing block is improved on this basis. Its manufacturing method is the same as that of the folding block, except that the folding part of the fiber blanket is cut off after molding to make the surface of the module flat. At present, some domestic manufacturers can produce this module. Palo block is a new module. Its forming method is completely different from the above two modules. The formed module fiber has no directionality, so the thermal insulation effect is better than the first two modules. The density of furnace top fiber module should be 230 kg / m3, and the density of side wall fiber module should be 220 kg / m3.
