Brick of Mo Laishi heat preservation is the heat preservation brick that is main raw material with Molaishi, general alumina content is in 45% ～ 65% 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.
Ultimate cluster is main and divisional means with JM series: JM23, JM26, JM28, JM30, JM32, distinction is main with fireproof degree to differentiate, cent is 1250, 1350, 1450, 1550, 1650.
Brick of heat preservation of JM series Mo Laishi is characteristic:
1, rate of low heat conduction, have effect of very good adiabatic heat preservation;
2, low hot frit, 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 hot condition compression 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, 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.
Advantage of brick of heat preservation of JM series Mo Laishi:
1, fireproof degree taller, right high temperature resistant have very good use value.
2, can contact directly with Xiang Huo face, can replace the use of heavy qualitative brick.
3, compare with photograph of brick of traditional heat preservation, intensity of normal temperature compression is high,
4, 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.
This series product is used high pure raw material reachs the distinctive technology that make, utmost ground avoided foreign matter and structural blemish to taste the influence of function to making, have stability of extremely excellent high temperature bulk and thermal shock stability; And intensity is high, coefficient of thermal conductivity is low, can contact the characteristic such as blaze directly. To all sorts of furnace model have extensive adaptability with all sorts of environments, the liner of industry kiln furnace such as gold of usable Yu Ye, mechanical, pottery and porcelain, chemical industry (do not suffer melt liquid to erode) reach heat-insulation layer, it is a kind of good energy-saving product.
