Heat preservation brick
Firebrick and heat preservation brick cannot be replaced each other, same capable person falls with content character, their utility is different, the compression intensity that pledges again is tall, wear-resisting, durable, prolong life, of heat preservation is to reduce prediction of a person's luck in a given year of quantity of heat, density and compression are small, not of wear-resisting.
Firebrick is one kind has the stuff of pottery and porcelain of stability of tall fireproof sex, high temperature and chemical stability, use at the liner of high temperature equipment or housing materials normally. Firebrick has very good stability below high temperature environment, can bear high temperature and chemistry are corroded. The main characteristic of firebrick is high temperature resistant, can bear normally the high temperature of 1500 ℃ above.
Weigh qualitative firebrick
Heat preservation brick is a kind of light qualitative heat-insulating material, its are main the characteristic is heat preservation heat proof quality good, weight is light, coefficient of thermal conductivity is low, use at kiln furnace heat-insulation layer and adiabatic layer. Heat preservation brick normally not wear-resisting, its use temperature to be in commonly under heavy qualitative firebrick.
Accordingly, firebrick and heat preservation brick cannot be replaced each other. The need when choosing material chooses right stuff according to particular use environment and requirement, in order to make sure material can work normally, and have longer service life.
