Molaishi in fireproof material and 2 Molaishi are distinguished

Molaishi and 2 Molaishi are two kinds of different fireproof material, their distinction depends on their manufacturing process and physical property. Molaishi is to point to the Molaishi that gets from the fire in ore directly, its bases is siliceous aluminium calcic stone, its crystal structure submits board form or columnar, because this has very good compressive strength and heat-resisting property, use at the liner of kiln of high temperature agglomeration and smelting furnace normally. 2 Molaishi is to show from inside Molaishi extraction comes out again the Molaishi that agglomeration gets, its bases is 2 oxidation silicon and aluminous oxide, its crystal structure is shown acicular or fiber shape, because this has very good fireproof function and heat conduction property, use at the place such as high temperature boiler setting and roof normally.


Molaishi and 2 Molaishi have the following to distinguish on attribute: 1, composition is different: Molaishi's bases is siliceous aluminium calcic stone, and 2 Molaishi's bases is 2 oxidation silicon and aluminous oxide. 2, crystallization pattern is different: Crystal structure of Molaishi submits board form or columnar, and 2 times crystal structure of Molaishi is shown acicular or fiber shape. 3, density is different: Molaishi's density is normally between 2.8-3.0g/cm3, and 2 Molaishi's density is normally between 2.4-2.6g/cm3. 4, compressive strength is different: Because not come,the crystal structure of stone submits board form or columnar, accordingly its compressive strength wants prep above 2 times normally Molaishi. 5, heat-resisting function is different: Heat-resisting function of Molaishi wants excel 2 times Molaishi, because its bases silicon acid is aluminous calcic stone is had very good high temperature resistant function. 6, heat conduction function is different: Because not come 2 times,the crystal structure of stone is shown acicular or fiber shape, accordingly function of its heat conduction is close friends normally at Molaishi.
The place on put together is narrated, although Molaishi and 2 Molaishi belong to fireproof material, but differ somewhat in the respect such as function of configuration of composition, crystallization, density, compressive strength, heat-resisting and heat conduction function, because this needs a basis when use,particular case chooses right stuff.
