Silicon pledges adiabatic firebrick uses temperature

Silicon pledges adiabatic firebrick is main raw material to be made with silica namely, siO2 content is not less than the adiabatic firebrick of 91% . Silicon pledges adiabatic firebrick is divided outside having property of adiabatic heat preservation, retain the character of silica brick greatly, loading bate begins temperature tall, heating in the process, bulk expands somewhat, make the integral sex of kiln furnace increases.

Production silicon pledges adiabatic firebrick uses the silica that passes grinding to be raw material, join a part to abandon silica brick or abandon silicon to pledge pink, mineralizer and burn oneself out join adiabatic firebrick content. By water is added to mix pug in deserving to mix experienced machine than be in certainly, classics machinery or handiwork shape, leftover moisture is less than after firebrick adobe is dry 0.5% can loading of kiln. To because SiO2 is much,prevent brilliant change occurs acuteness bulk to expand, cause firebrick to produce crackle, firing when the demand is slower litre drop in temperature speed.

Ministry of Chinese metallurgical industry occupation standard YB386, the industrial furnace of 63 regulations uses silicon qualitative heat insolation firebrick QG, 1.2 brands product lives can: Bulk density is not more than 1.2g/cm3, intensity of normal temperature compression is not less than 3.43MPa, fireproof degree not under 1670 ℃ , bate of the loading below 0.098MPa begins temperature to not be less than 1560 ℃ , siO2 is less than 91% .

This firebrick applies to build by laying bricks or stones to build working temperature not to exceed 1560 ℃ , as not direct as stock of high temperature melt contact and the industrial furnace lining that do not accept aggressivity gas action continuously or use at thermal insulation.

Firebrick of silicon qualitative heat insolation because silica dust is big to human body harm, process is more complex than argillaceous brick and tall aluminous brick, in adiabatic and fireproof material the place in total output holds proportion very small.
