Argillaceous sincere brick

The use history that argillaceous sincere brick is in China is long, although argillaceous brick is now in actual application,put in a lot of insufficient place. But as a result of the price simple, design mixes cheap, technology the use of construction technology maturity and people is inertial wait for a reason, argillaceous sincere brick still is holding dominant position in construction project field. We also innovate in ceaseless research and development in the light of argillaceous brick, believe to position is had as before in the fireproof data market in future.
Now, make us simple know argillaceous sincere brick. The main raw material of argillaceous sincere brick is opaque or arenaceous qualitative clay, its are main chemical composition is SiO2, Al2O3 and Fe2O3 and crystallization water, what create a condition as a result of geology is different, the likelihood still is contained a few alkali metal and alkaline-earth metal oxide. The manufacturing technology of argillaceous brick basically includes to take mashed vegetable or fruit of earth, refine, make base, dry, roast wait.


Argillaceous sincere brick is the sophisticate material that needs to join with clay and basis for raw material, via adding water agitate, shape, high temperature roast and the sincere brick that makes. The standard of argillaceous sincere brick that we establish from the country can know, the density of argillaceous sincere brick is 1.7 grams every are cubic centimeter, namely 1700 kilogram every stere.
Brick of fire clay sincere is a technology, of argillaceous sincere brick make the fire temperature that cannot leave it. It is roast temperature control is between 1100 ℃ of 900 ～ commonly, make adobe burns to partial melt agglomeration. Circumstance of fire of body of a few kinds of bricks is below:
1, if roast temperature passes tall or time is too long, had produced firebrick easily. The characteristic of ham brick is sound of kind of deep, knock fragile, be out of shape wait greatly.
2, if roast temperature passes low or time is insufficient, easy generation owes firebrick. The characteristic of underfire brick is sound of kind of shallow, knock dumb, intensity is low, bibulous lead big, wear difference to wait.
3, it is oxidation atmosphere when the roast in brickkiln, because generate 3 ferric oxide (Fe2O3) and make the brick shows red, call red brick.
4, if be in oxidation atmosphere firing hind, cover tightly in reducing atmosphere again kiln, oxidation of gray of gules Fe2O3 reductive Cheng Qing is ferrous (FeO) , call blue bricks. Blue bricks is general relatively red brick compact, alkali resistance, wear is good, but because the price is high, manufacturing application is less.
5, in addition, in production in can waiting for the fly ash with the cindery, high volume that contain carbon industrial flotsam mix into to enter the land that makes semifinished product, make inside light a brick. The brick is lighted inside combustion is even, apparent density is small, coefficient of thermal conductivity is low, and intensity can rise about 20% .


According to the regulation of national level GB 5101-2003, the technology of argillaceous brick asks to include the field such as grade of quality of appearance, dimension, exterior, intensity and wear. Mix according to frost of dimension deviation and exterior quality, extensive lime blowout cent is classy article (A) , first-rate product (B) taste with qualification (C) 3 grade.
Among them the intensity grade of argillaceous sincere brick is worth according to the compressive strength average of 10 bricks, standard or little value differentiates, divide in all for MU30, MU25, MU20, MU15, MU10 5 grade.
Argillaceous sincere brick has particular strength already, have property of better heat insolation, sound insulation again, and the price is low.


Argillaceous sincere brick can be used at the building to maintain a structure, build by laying bricks or stones builds body of column, arch, chimney, kiln, raceway groove and foundation to wait. Can wait for heat-insulating material form a complete set to use with cotton of light aggregate concrete, aerocrete, cliff, build by laying bricks or stones is a brick into two sides, among fill the small system wall with light simple stuff. Proper reinforcing steel bar or net of reinforcing steel bar can be configured to become build by laying bricks or stones matching veins that stand out under the skin to build system in body of build by laying bricks or stones,
Although firebrick of current our country produces craft to progress ceaselessly, but fired brick is in henceforth inside period of time, in still can be being used at build by laying bricks or stones to build a project as a kind of main material. In the meantime, we innovate in the light of the research and development of argillaceous sincere brick, will give this kind of firebrick new vitality.
