Value of par of state of brick of Mo Laishi heat preservation

 1,

High temperature Mo Laishi pledges the brick is the new technology that our country introduces, home's newest energy-saving and fireproof material, have high temperature resistant, strength tall, coefficient of thermal conductivity is small, energy-saving the effect is distinct wait for a characteristic, apply to oil to crack roller of hot-blast stove of interpose furnace, metallurgy, pottery and porcelain kiln of crucible of kiln of drawer of porcelain of path kiln, channel kiln, report, glass and all sorts of electric stove liner, can contact blaze directly, reach via supervising a branch to detect about the technology use, the product reachs the technical target of foreign congener product.

2, brick of Mo Laishi heat preservation is with Molaishi (3Al2O3·2SiO2) the expensive aluminous simple fireproof stuff that gives priority to brilliant photograph. General alumina content is in 65% ～ 75% between. Mineral composition divides Molaishi outside, contain alumina among them inferior person still contain a few glass photographs and Fang Shiying; Contain alumina taller person still contain a few corundum. Brick of Mo Laishi heat preservation can be used at liner of furnace of high temperature kiln directly, use extensively already at the liner of shuttle type kiln, roller path kiln, glass and petro-chemical kiln furnace at present.

One, the item characteristics of brick of Mo Laishi heat preservation:

1, rate of low heat conduction, have effect of very good adiabatic heat preservation;

2, frit of low heat of brick of Mo Laishi heat preservation, because low heat conduction is led, mo Laishi series pledges gently the heat energy with adiabatic brick very few save up, energy-saving in intermittent operation effect is apparent; 3, matter content is low have the oxide content such as alkali metal of low-down iron box, accordingly, fireproof degree tall; The higher volume that contain aluminium makes its still maintain good performance below reducing atmosphere;

4, intensity of compression of hot condition of brick of Mo Laishi heat preservation is high;

5, exterior size is exact, accelerate build by laying bricks or stones to build career, reduce fireproof mud to use an amount, assured the intensity of body of build by laying bricks or stones and stability, prolong the life of liner thereby;

6, brick of Mo Laishi heat preservation can process special form. Seam in order to reduce number of brick of build by laying bricks or stones and build by laying bricks or stones.

2, the classification of brick of Mo Laishi heat preservation: The different and main component of brick of Mo Laishi heat preservation according to density weighs qualitative Molaishi to be mixed gently character brick, according to using temperature different and main component is: Bricks of bricks of 1350 Mo Laishi heat preservation, 1450 Mo Laishi heat preservation, 1550 Mo Laishi bricks. The function of brick of Mo Laishi heat preservation reachs his to apply: Fireproof degree taller, can amount to 1790 ℃ above. Loading bate begins temperature 1700 ℃ of 1600 ～ . Intensity of normal temperature compression 70 ～ 260MPa. Heatproof shake sex is good. Have agglomeration Mo Laishi brick and electric frit Mo Laishi brick two kinds. Agglomeration not comes stone brick is main raw material with tall aluminous aluminous grog, join a few clay or unripe alumina to make bond, via shaping, firing and make. Electric frit not comes stone brick is raw material with alumina of tall alumina, industry and fireproof clay, join charcoal or coke granule to make reducer, law of reductive report frit is used to make after shaping. The crystallization of electric frit Mo Laishi is bigger than agglomeration Mo Laishi, heatproof shake sex is better than agglomeration goods. Their high temperature capability basically depends on the uniformity that the content of alumina and glass of Mo Laishi get along with distributing. Basically use at lining of blind angle of system of splitting decomposition of kiln of agglomeration of regenerator of kiln of frit of shaft of hot-blast stove roof, blast furnace and hearth, glass, pottery and porcelain, oil to wait.

3, bulk density of the brick is in common light qualitative Molaishi 0.6-1.2g/cm3, the bulk density of firebrick of heavy qualitative Mo Laishi is in 2.3-2.5 G/cm3. The bulk density of Mo Laishi brick does not have fixed standard to set, specific it is actual level with client demand.

4, the comprehensive report that index of density of bulk of Mo Laishi firebrick is amount of volume of the stoma in Mo Laishi brick and mineral composition, because determine more easily, aborning regards judgement as the method of degree of agglomeration of Mo Laishi brick normally. The factor that affects density of bulk of Mo Laishi firebrick has the following two respects: The bulk density of the alumina content that is Mo Laishi brick reachs the size of alumina granuality, it is the control that produces process on the other hand. When producing firebrick of the Mo Laishi that make accordingly, need chooses the control of the grade of raw material and grain strictly, in the process that make control controls the pressure of adobe of bricky machine suppress, of firebrick of Mo Laishi of reasonable control firing.
