Abstract
The invention discloses a kind of preparation methods of anticorrosive pressure-resisting type bearing bricks, belong to building material technical field.According to parts by weight, it successively weighs: 30~50 parts of quartz sands, 20~30 parts of red muds, 10~25 parts of flyash, quartz sand and red mud mixing and ball milling are obtained mixture by 10~12 parts of modified potassium tetratitanates and 10~15 parts of modified fibres, mixture is mixed with flyash, and modified potassium tetratitanate and modified fibre is added, after being stirred, obtain blank, under conditions of being 800~1250 DEG C in temperature by blank after 3~5h of heat preservation sintering, anticorrosive pressure-resisting type bearing bricks are obtained.Gained anticorrosive pressure-resisting type bearing bricks of the invention have excellent compression strength and corrosion resistance.
Description
Technical field
The invention discloses a kind of preparation methods of anticorrosive pressure-resisting type bearing bricks, belong to building material technical field.
Background technique
Traditional no-baking bearing brick is mainly with cement works granulated garbage or slag granules, quick lime, flyash, through stirring
After mixing the repressed molding of machine dehydration stirring, conserves 20~30 days finished product is made under field conditions (factors).Bone used in this bearing bricks
Material building waste contains powder, complicated component, unstable quality, and intensity is low.Some of them product can after finished product is made
Decomposition can be also reacted, the stability of brick quality is influenced.Quick lime used can be cured first in stirring molding and after molding,
Reacted afterwards with pulverized burned coal ash hydration, but the curing of leather hard quick lime is not thorough, with flyash be not easy to be uniformly mixed it is abundant, with
Pulverized burned coal ash hydration reacts insufficient, leverages the generation of brick stable elements.Especially after shaping, thin of quick lime
Grain cures again, and the internal stress of destruction is easily generated in brick, such as length occurs and split, and causes product unqualified.Although using nature
Under the conditions of maintenance, saved the energy, but curing time is too long, the brick of compression moulding made to be in the unstable shape of composition for a long time
State, and sufficient hydration reaction is actually finally not achieved, make finished bricks unstable quality.Natural curing is not suitable for industrial metaplasia
It produces.The brick intensity generally produced in batches is only at 7.5 grades.Some proportion ranges of choice are wide, for different flyash compositions, institute
The range of choosing is inappropriate, is that the effect is not achieved.Especially in the technical process of production flyash brick, raw material
It is mixed together, it cannot be guaranteed that being sufficiently mixed and contacting between reactant, leads to unstable quality in actual production, certain original occur
Material is assembled in fraction.Some mixed process only stirs, and rolls or first rolls after some first stirrings and stirs afterwards, all cannot be quick
Effectively mixing is abundant.Pressure used in pressing process only has 20MPa or so, cannot make to reach effective contact between reactant
Consistency.The maintenance of adobe is any selection natural curing, and the reactant that the arbitrariness of maintenance cannot be guaranteed sufficiently dissolves infiltration
Thoroughly, make reaction not exclusively, and to generate internal stress and crackle.More important is, existing technology is only studied in ingredient,
And technical process is then arbitrary selection, not can guarantee reasonable ingredient in production process technology effectively sufficiently reacts, and is formed steady
