Description
Technical field
The present invention relates to the material for repairing of the ceramic fiber shrinkage joint of resistance to material in a kind of stove.
Background technology
At present, at home, variously take ceramic fiber material and be that the various fire-resistant heat insulating materials on basis obtain applying more and more widely, comprise the ceramic fiber blanket using in various kilns, ceramic beaverboard, ceramic fiber block etc.Due to the characteristic of ceramic fiber itself, it has certain shrinking percentage, is presented as the contraction for 1%-3% greatly under its use temperature, so there will be gap after having grown duration of service, and we are called shrinkage joint.General heat insulation employing ceramic fiber module is unit, the height of conventional ceramic fiber module is 300mm, wide is 300mm, thickness is 200-300mm, due to thermal pinch effect, height and width have the contraction of 3mm-9mm, form width 3mm-9mm, the degree of depth has the narrow slit of 200-300mm, and gap very deeply but very narrow.In domestic at present a lot of situation, use ceramic fiber loose wool to fill, use instrument is bit by bit filled in inward, until jam-pack plug is real.Very inconvenient in use, and inside exists a lot of spaces in fact, the result of generation is exactly, and the furnace wall portion temperature that shrinkage joint is corresponding raises, and heat loss is large, and power consumption raises, and adopts the workload of this kind of method trimming also larger.
According at present, ceramic fiber cotton blanket and chunk can not be substituted in long time, so, must have the materials and methods that can easily repair it, and need use and can be combined with starting material all much the same materials of tight and shrinking percentage thermal conduction.Therefore, need to develop a kind of adaptable repair material, solve this problem.
Summary of the invention
The technical problem to be solved in the present invention is: for overcoming the problems referred to above, provide a kind of easy to use, moulding onset effect is fast, can be by the material for repairing of the ceramic fiber shrinkage joint of resistance to material in the stove of injection filling.
The technical solution adopted for the present invention to solve the technical problems is:
The material for repairing of the ceramic fiber shrinkage joint of resistance to material in a kind of stove, its ingredients by weight percentage composition is: aluminum silicate fiber 7%-18%, sapphire whisker 2%-6%, aluminum oxide powder 10%-12%, mullite powder 18%-20%, silicon sol 5%-8%, the polyacrylamide solution 46%-54% of concentration 0.5%-1%.
Preferably, its ingredients by weight percentage composition is: aluminum silicate fiber 8%-12%, sapphire whisker 3%-6%, aluminum oxide powder 11%-12%, mullite powder 20%-21%, silicon sol 6%-7%, the polyacrylamide solution 47%-52% of concentration 0.5%-1%.
Preferably, its ingredients by weight percentage composition is: aluminum silicate fiber 9%, sapphire whisker 4%, aluminum oxide powder 11%, mullite powder 19%, silicon sol 7%, the polyacrylamide solution 50% of concentration 0.5%-1%.
The invention has the beneficial effects as follows: the present invention is simple in structure, by process improving and formula improvement, performance is far superior to common mode, is a kind of innovation.Density is 400-600kg/m3, and hardness is at Shao Shi more than 80, and folding strength is more than 0.6Mpa, and the lower thermal conductivity of 1000 degree is less than 0.15w/mk.Provide a kind of easy to use, moulding onset effect is fast, can pass through injection filling, is applicable to the material for repairing of all temps level; Can to the shrinkage joint of kiln, repair easily, eliminate the phenomenon that produces energy consumption rising because of shrinkage joint.Can effectively promote the efficiency of repairing shrinkage joint in stove, and improve the quality of repairing.
