One, function of brick of Mo Laishi heat preservation

 

With Molaishi (the expensive aluminous simple fireproof stuff that 3Al2O3·2SiO2) 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; to contain alumina taller person still contain a few corundum.

 

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.

 

 2, 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.

 

Brick of Mo Laishi heat preservation, differ according to density can divide for: The brick mixes light qualitative Molaishi to pledge again Mo Laishi brick;

Can divide according to applying temperature to differ for: 1350 Mo Laishi bricks, 1450 Mo Laishi bricks, 1550 Mo Laishi bricks.


The main characteristic of brick of Mo Laishi heat preservation:

1. green environmental protection, avirulent, without corrode, but safety is used.

2. and cement adaptability are good.

3. pledges heat preservation brick uses epispastic mechanism bubble gently the bubble with attainable bubble even diameter.

The bubbly performance with superior 4. , epispastic multiple can amount to 30 times above.

 

3, brick of Mo Laishi heat preservation produces craft manufacturer

Synthesize the manufacturing technology of brick of Mo Laishi heat preservation to have: (electric frit law and agglomeration law) , measure 1. The choice of raw material must want pure, by Molaishi academic composition has burden, classics is sufficient fine grind, into the ball (or press into makings piece) . 2. High temperature to calcine and into. Agglomeration law synthesizes brick of Mo Laishi heat preservation.  

     The recipe that home used a few days ago is main by the following kinds: ; Industrial alumina + silica; (kaolin or dried meat stone) corundum (α—AL2O3)+ silica. Industrial alumina + tall aluminium is aluminous (or silicon line stone a group of things with common features raw material concentrate) the burden that at present my factory production synthesizes Molaishi with natural tall aluminous alumina + kaolin, industrial alumina + clay, two kinds are given priority to. 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.

     
     Mo Laishi brick is fireproof degree taller, can amount to 1790 ℃ above. Loading bate begins temperature 1700 ℃ of 1600 ~ . 260MPa of ~ of 70 of intensity of normal temperature compression. 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 that agglomeration Mo Laishi compares electric frit Mo Laishi is small, 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 kiln of agglomeration of lining of blind angle of system of splitting decomposition of regenerator of kiln of frit of roof of blast furnace shaft and hearth, hot-blast stove, glass, oil, pottery and porcelain to wait. Mo Laishi firebrick has high structure of loading bate temperature it is compact, good to fight aggressivity, porosity is low characteristic.
