Abstract
The invented fly ash sintered brick uses fly ash and expanded pearlite as main raw material and dopes with small amount of bentonite and clay, then mixes and is pressed into form, and sintered into brick. The invented brick possesses the advantages including: low weight per volume, good heat insulating property, saving land etc.
Description
A kind of manufacture craft of coal ash sintering brick belongs to building material field, relates in particular to its manufacture craft.
In China building brick manufacturing field, the manufacturing process of fired fly ash brick is arranged.But this sintering process is to be shaped to roll the bar cutting, and therefore capable again roasting requires composition material to possess enough viscosity, so its composition also only limits to flyash and clay etc., under the situation that current land resources reduces day by day, is unfavorable for protecting land resources.
Publication number is the invention of CN_1105346A, discloses the application for a patent for invention of a kind of " insulating brick and preparation method thereof ".It to the effect that is made up of the pearlstone of the flyash of 55%-58%, 25%O-35% and cement, waste and old polyphenyl foam plastics particle (weight ratio), adopts pressing process to be made.It is this that what be made without sintering is the brick of major ingredient with flyash, because carbon weathering behind certain hour that flyash includes, thereby make brick loose, so use this brick that very big hidden danger is arranged, therefore, there is strict requirement in country to the carbon content of this brick, has also done certain restriction in the use.
Purpose of the present invention, exactly at above-mentioned be the batching of brick of major ingredient and the deficiency of production technique with flyash, invent and a kind ofly can economize on soil, can implement the coal ash sintering brick manufacture craft of sintering process again.
Technical scheme of the present invention is, becomes compound by raw material stirring such as flyash, pearlstones, it is characterized in that: mix wilkinite about 5%-10% and the clay of 5%-10% in raw material, be shaped with pressing mode, carry out roasting again
Further technical scheme of the present invention can be by the complete instead of clay of wilkinite, and volume ratio accounts for 15%-20%.
Adopt technique scheme, its advantage is: the brick unit weight of making is little, thermal and insulating performance good, energy-conservation, saving land resources; Adopt sintering process, the carbon in the flyash burnouts mostly, has avoided the hidden danger in its use; Simultaneously, the every performance index of the brick of making all meet the requirement of building code.
Below, with relevant data above-mentioned advantage of the present invention is described: name of product flyash sintered hollow block argillaceous and wilkinite specification are the qualified water-intake rates 29% of 621 kilograms of/cubic metre thermal conductivity 0.14W/MK of 240*240*180 hole ratio 26.2% unit weight water ratio, 3.15% coefficient of softening, 0.99 big compressive strength for surface contact 3.15MPA bar compressive strength for surface contact 15 intact sizes of 2.35MPA freeze thawing
Above-mentioned data are light-duty non-load bearing tile detected result, meet the requirement of GB-13545-92 first grade fully.Because the brick unit weight that the present invention makes is little, thermal conductivity is little, so available thin brick structures reaches the service requirements of enclosure wall, thereby significantly alleviate the basic load-bearing of buildings, can save a large amount of resources.
With the wilkinite instead of clay, it makes the GB requirement that the every performance index of brick can reach bearing wall, thereby in field application widely.
Below, in conjunction with the embodiments, specify the present invention: 0.8 cubic metre of material perlite
1.2 cubic metres in flyash (flyash that forms with the accurate Ge Er coal in Inner Mongol is example)
0.4 cubic metre of main technique of wilkinite (1) bentonite in powder changes into mud
(2) mixing sequence ligand one mud two mixes the flyash three that stirs and adds perlite
(3) moulding moulded machine compression moulding
(4) formula that the combines between the higher and lower levels long tunnel kiln of design is voluntarily adopted in roasting
600-700 degree Celsius begins to soften, and the 800-1100 degree forms the silicon body.
Concrete maturing temperature will be determined according to flyash and bentonitic composition.End properties is an example with the 240*115*90 solid brick
Unit weight 750-800 kilogram/cubic meter
Thermal conductivity 0.14W/MK
Water ratio 3.15%
Coefficient of softening 0.99
Big compressive strength for surface contact 11MPA
Bar compressive strength for surface contact 9MPA
Freeze thawing is intact
Size is qualified
Water-intake rate 29%
By as can be seen above-mentioned, the brick that the present invention makes, its every performance index all meet or exceed the requirement of bearing wall with brick.
Claims (4)
1, a kind of manufacture craft of coal ash sintering brick becomes compound by raw material stirring such as flyash, pearlstones, it is characterized in that: mix tackiness agents such as wilkinite about 15%-20%, clay in raw material, be shaped with pressing mode, carry out roasting again.
2, the manufacture craft of a kind of coal ash sintering brick according to claim 1 is characterized in that: wilkinite and clay stir in advance, join with flyash mixed again, add pearlstone at last, stir into compound.
