Are light qualitative firebrick and brick of light qualitative heat preservation same?

Light qualitative firebrick is one kind has system close result of small, favorable adiabatic heat preservation, its action and utility and brick of light qualitative heat preservation are same, detailed introduction looks please below.

The advantage of light qualitative firebrick is long-term high temperature resistant function is very good, defect is difference of heat proof quality. The air hole in light qualitative firebrick is made through adding the light aggregate such as combustible, vesicant or hollow ball, stomatic size is larger. These stoma not only adiabatic effect is not tall, still affect the mechanical performance of goods. If increase stomatic bulk mark, aperture of a lot of air can reunite together, affect the intensity of adiabatic brick. The lump heat insolation that the sort of light qualitative adiabatic firebrick and workmanship pledge adiabatic firebrick fastens in-house and poriferous structure to have adiabatic property gently is fireproof goods, it is with the production of bricky form product and application among them extensive, reason calls light qualitative adiabatic firebrick again. Light qualitative adiabatic firebrick uses raw material to be able to be divided by place for clay qualitative, silicon pledges, aluminium pledges and Molaishi pledges etc. Sex of difference of the low, function that fight broken bits, heatproof shake needs the compression strength of light qualitative firebrick, cannot contact directly with vitreous fluid or blaze. Light qualitative brick can adiabatic because many stoma is contained inside bricky body,be (include closed pore and open pore) . The method that creates air hole has: Add chemical way of; of law of bubble of combustible law; . But, the area comparing a list of light qualitative firebrick is inferior, can more inferior than the surface. Consequently, thermodynamic stability is better. Be heated is long-term after action, produce metamorphism not easily. What do light qualitative firebrick and the distinction that weigh qualitative brick have? Heat preservation brick and firebrick basically distinguish have the following: 1. The coefficient of thermal conductivity of brick of heat preservation of heat preservation function is in commonly 0.2-0.4(average temperature 25 ℃ of 350 ± ) W/m.k, and the coefficient of thermal conductivity of firebrick is in 1.0(average temperature 25 ℃ of 350 ± ) W/m.k above, many the heat preservation performance that can reach the heat preservation function of heat preservation brick wants to compare firebrick from this is good. 2. Fireproof those who spend heat preservation brick is fireproof degree be in 1400 degrees commonly the following, and of firebrick fireproof degree in 1400 degrees of above. 3. Brick of density heat preservation is light qualitative insulation material commonly, density is general the density of in 0.8-1.0g/cm3 firebrick is in basically 2.0g/cm3 above. Integrated for, the mechanical intensity of firebrick is high, use cycle is long, and chemical stability is good, as not chemical as stock happening reaction and high temperature resistant performance is good, tall heat-resisting temperature can achieve 1900 ℃ . Special apply to fertilizer plant discretion lukewarm commutation furnace, in changing furnace of alkylation of chamfer of converter of furnace, hydrogenation, to decoke and armour, how much is price of light qualitative firebrick? Clear up the following problems to just go: 1, the particular use case of the kiln heat that you use, if use temperature, whether to contact blaze to wait; 2, the sort that wants light qualitative firebrick, use normally basically include: Brick of light qualitative clay, light qualitative aluminous brick, diatomite brick, light qualitative Molaishi the brick, the price of these a few kinds of material also is distinguishing; 3, the norms that the price that clears up light qualitative firebrick needs to know firebrick and dimension, other measure also clears up ability travel. Are light qualitative firebrick and brick of light qualitative heat preservation same? Through the everybody inside above the look can be clear about know, this is a kind of refractory products actually, if have other doubt,greeting incoming telegram seeks advice.
