Description
Technical field
The invention belongs to tamanori technical field, be specifically related to a kind of high-temperature agglomerant and method for making thereof based on inorganic components.
Background technology
After the energy dilemma, the cry of worldwide save energy is more and more surging, and each state all begins to be devoted to energy-conservation and consumption reduction work.The eighties of last century ceramic fiber forties is developed success, because of it has excellent performances such as refractory heat-insulating, is promoted being applied on the various Thermal Equipments, has brought into play the great energy-conservation and effect that lowers consumption, also by the 5th energy that is called of people's cordiality.Along with continuous advancement in technology and maturation, the application of ceramic fiber is constantly expansion also now, especially various fibre modules, and quilts such as fiber tangent plane piece are directly used in the fiery face of quilt of Thermal Equipment, and energy conservation and consumption reduction effects is obvious day by day, and use properties also obtains to such an extent that promote.
But, as ceramic fiber, itself be that pore and solid get combination, void content have up to more than 90%, this also is its reason with excellent heat-insulating capability.But loose relatively structure also restricted ceramic fibre and air-flow situation more complicated higher in internal gas flow speed Thermal Equipment on application.On the other hand, product all is to be fixed on the wall liner of equipment by resistant to elevated temperatures metal anchorage in the general module, yet for the less module class product of some sizes, traditional anchorage style difficulty is bigger, constructional difficulties, and effect is poor.
At above problem, the development high-temperature agglomerant is proposed, this binding agent is mainly used in bonding between ceramic fibre and the ceramic fibre or the bonding between the non-ceramic fiber fire resistant insulation products of ceramic fibre, adopt this product can effectively improve the bulk strength of product insulation construction, and alleviated difficulty of construction greatly.
Summary of the invention
The purpose of this invention is to provide a kind of high-temperature agglomerant, be mainly used in the bonding of ceramic fiber module, it has makes simple, low, the use temperature advantages of higher of cost.
The following technical scheme of the concrete employing of the present invention
