Abstract

The invention discloses a production method of an aluminum silicate inorganic fiberboard. In the invention, water, instead of organic fiber lubricant, is used as fiber lubricant. The invention can produce the aluminum silicate fiberboard without using any organic raw material, and ensures the product quality.

Description

technical field [0001] The invention relates to the field of production of aluminum silicate fiber boards, in particular to a production method of aluminum silicate inorganic fiber boards. Background technique [0002] Manufacturers who produce PDP need to use a large amount of inorganic refractory fiberboards that do not contain organic matter in the PDP firing furnace. At present, there are also 1260 inorganic fiberboards being produced in China, but the main raw materials and processes are mixed with organic matter, and the organic matter is removed by post-firing method, but this method cannot guarantee 100% removal of organic matter, and there are still some residues. In the demanding PDP industry, it still has a negative impact on product quality. The main way of mixing organic matter is: use aluminum silicate fiber blanket as raw material. Aluminum silicate fiber cotton will use fiber lubricant in the production process of blowing or spinning, so that it can be need...
