1350 light qualitative Molaishi bricky price and index

   Pledge Mo Laishi brick calls Molaishi adiabatic firebrick again gently, basically be the fireproof material that gives priority to mine photograph character with siliceous aluminium, have a few good performance, (especially function of high temperature creep) the high aluminous products that is on production of natural raw material is consummate.

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

3, brick of light qualitative heat preservation uses epispastic mechanism bubble the bubble with attainable bubble even diameter.

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

     Mo Laishi (Mullite) it is AL2O3-SiO2 n duality the binary compound that fastens middling to press next stability to exist, chemical type is 3AL2O3, 2SiO2, theory comprises AL2O3, 71.8% , siO2 28.2% . Mo Laishi is mineral name, discover Yusugelanxi because its are natural and mineral earlier Mo Er island of the coast (Mull) and get a name. Heibei of mineral and special exiguous our country saves natural Molaishi province forest county discovers Wu An county and Henan somewhat, but have not see the deposit that has industrial value to this age bound. Mo Laishi uses agglomeration law or electric frit law to wait to close artificially normally. Synthesize Molaishi to be gotten at using capacitance legal system above all 1926, developed successful agglomeration way 1928. Year of wastage of Mo Laishi of frit of electrify of eye preexistence bound for 10000-20000 ton, agglomeration Mo Laishi is 500000-600000 ton. Synthesizing Molaishi is a kind of high grade fireproof raw material, it is had expand stability of even, thermal shock creep of tall, high temperature is worth softening point of wonderful, loading small, hardness is big, fight chemistry caustic wait for a characteristic. The Mo Laishi brick that Mo Laishi makes is first-rate with. Crystal structure of Mo Laishi belongs to inclined Fang Jing to fasten, it is a kind of silicon line rock that has oxygen room drawback (AL2O3.SIO2) structure, very as similar as structure of crystal of silicon line stone. Synthesize Mo Laishi sort to have a lot of. Have agglomeration Mo Laishi and electric frit Mo Laishi by complex method; By raw material chemistry composition has low aluminium Molaishi, medium aluminous Molaishi, tall aluminous Molaishi and zirconium Molaishi; If press an use raw material sort,have to calcine kaolin (low aluminium) , to calcine cyanite (in aluminous) , round-the-clock fuel Mo Laishi (tall aluminium) , high pure Molaishi.  

     But because Molaishi is mineral exiguous, rely on artificial synthesis only so, complex Mo Laishi mixes according to certain proportion, the stabilizes exclusively compound in this system can be formed below constant temperature, not come namely stone crystal. And compositive AL203 of Molaishi is in 79% the left and right sides, SI02 is in 21% relatively appropriate, but the foreign matter composition with a certain quantity of existence in raw material, composition report will be created below high temperature, accordingly as increase of foreign matter part, can make glassy with corundum content grow in quantity, make Molaishi forms structure of thick any crystalline substance, make thereby goods porosity heighten, thermal shock stability and fight aggressivity to be able to be reduced, appear easily interstitial.

   Accordingly manufacturing technology of Molaishi has two kinds, agglomeration law and electric frit law. Synthesizing Molaishi is to use industrial alumina, hydroted alumina and pure clay (the kaolin of small foreign matter) and Xie Lashi as raw material, also have use tall aluminous alumina to add clay, or synthesize Molaishi to be used at making brick of Mo Laishi heat preservation wait for goods directly with tall aluminous alumina.

 
   With Molaishi (3Al2O3·2SiO2) the light qualitative Molaishi that gives priority to brilliant photograph brick. 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, fireproof degree taller.

The character of brick of Mo Laishi heat preservation:

The function of brick of Mo Laishi heat preservation, fireproof degree very tall, highest and OK counteractive the high temperature of 1800 Celsius, but in 1600 to 1700 Celsius when heat preservation brick can begin bate, won't burn. Next its compression is spent tall also, it is probably in 260M/pa in the limit of.

As to Molaishi how is heat preservation brick made. It is by tall aluminous alumina clinker gives priority to material, add a few clay. Protect clay resource well, not come so the gives uptodate and modern science and technology product of brick of stone heat preservation, aluminium is the thing that the noble just can use previously, but modern technology makes this kind of resource can use aluminium to produce all sorts of product.

Basis of brick of Mo Laishi heat preservation of density differ to be classified somewhat, cent not comes to pledge gently brick of stone heat preservation and brick of heat preservation of heavy qualitative Mo Laishi, what the basis uses temperature is different, cent is 1350 Mo Laishi bricks, bricks of 1450 Mo Laishi heat preservation, 1550 Mo Laishi bricks, above of 1550 Mo Laishi brick use the brick that regards igneous cellar as and so on commonly, because the temperature of heat-resisting is high.

Price aspect not comes to the manufacturing technology of stone brick and manufacturing area gently character different valence also has not small error, the judgement more of the price is to follow the norms dimension of the product to ask to concern, bricky price is in groovy light qualitative Molaishi probably 3000 to 5000 differ, particular value can seek advice with the incoming telegram.
