Description
Technical field
The invention belongs to technical field of refractory materials, be related to sial fire resistant materials, more particularly to a kind of Alkali resistant brick and
Its preparation method.
Background technology
China is manufacture of cement state maximum in the world, and 2011, China's cement output accounted for global cement up to 2,000,000,000 tons
The 60% of total output, new dry cement production technology also obtains rapidly large-scale popularization, and the cement industry of China generally reflects
The World Water clay average level made.At present, position is in charge of in the kiln tail preheater of China's cement producing line, dore furnace and three times
Mainly use Alkali resistant brick.
Alkali resistant brick generally uses pocket clay clinker, high silicon fire clay and the soft flame-proof clay with good combination
It is made.According to existing standard, the alumina content of Alkali resistant brick should be 25-40wt%, if the content of aluminum oxide is more than 40%,
Alkali resistance will be damaged substantially；To improve alkali resistance, then require that Alkali resistant brick contains more K2O and Na2O, quickly to be formed
R2O-Al2O3Glass phase, and this can damage the heat-resisting quantity of Alkali resistant brick.
On the other hand, for the angle of resource, the reserves of China's bauxite account for the 5th, the world, and consumption is generation
The 1st, boundary, due to the long-term exploitation for robbing formula and a large amount of outlets, the bauxite resource of China is by heavy damage, fire proofed wood
Expect bauxite clinker, particularly high-quality high grade bauxite is in rather short supply, price constantly rises.
In summary, existing Alkali resistant brick defect in performance, and raw material mineral resources are also increasingly deficient, need hair badly
Substitution of resources technology is opened up to develop a kind of new sa Alkali resistant brick.Waste and old electroceramics is used as industrial rubbish always for a long time
Rubbish processing, growing with its quantity, the process problem of waste and old electroceramics also increasingly becomes the problem of puzzlement local government.
