Description
Technical field
The present invention relates to construction of a kind of ceramic fiber mechanically spraying or ceramic fiber ramming, the wedding agent in smearing, especially a kind of high temperature adhesives and compound method thereof that is used for dense form ceramic fiber lining.
Background technology
In recent years, ceramic fiber is high temperature resistant with it, vibration resistance, thermal insulation, sound-absorbing and advantage such as in light weight, part replaces brick structure and mould material and becomes fire-resistant, insulation, heat insulation, sound insulation, fp preferred material, and is used widely in industries such as metallurgy, oil, chemical industry, machinery, electronics, building, light industrys.It is the novel construction process that grew up in recent years that ceramic fiber adopts spraying, ramming, streak method construction, it has overcome that fritter fire-retardent fiber felt-rug furnace lining and acupuncture volume blanket " Z " shape folded piece lining globality is poor, seam is many, easily directional retraction produce connect that seam, difficulty of construction are big, long in time limit, Gas permeability greatly, be easy to shortcoming such as flue gas erosion, help improving the safety in utilization and the thermo-efficiency of Industrial Stoves, for industry energy conservation synergy provides a good approach.Therefore at present but because the wedding agent technology in the traditional fibre lining construction remains in some problems, also to exist intensity low for the ceramic fiber lining, subjects to mechanical collision and damage, water funk immersion, problem such as anti-thermal shock is poor, and it is big to repair difficulty, and Gas permeability is big.
Summary of the invention
The objective of the invention is to overcome that the backing layer intensity that exists in the existing ceramic fiber lining technology is low, waterproof and problem such as heat-shock resistance is poor, Gas permeability is big, a kind of dense form ceramic fiber high temperature adhesives is provided.
Dense form ceramic fibre high temperature adhesives provided by the present invention includes Al
