The effect with light qualitative main brick is to use heat preservation, reduce caloric prediction of a person's luck in a given year, light qualitative brick won't contact blaze directly commonly, and heavy qualitative brick contacts blaze directly commonly. Heavy qualitative brick basically is to use the broil that experiences flare-up to bake. General component is two kinds, do not finalize the design namely fireproof material and finalize the design fireproof material. Adventitious fireproof material:
Also cry pouring makings, be mix a kind by a variety of aggregate or collect makings or a variety of sticking and the mixture that the agent comprises is farinaceous a makings, one kind is mixed when using or a variety of liquids cooperate agitate even, have stronger liquidity. Finalize the design fireproof material: Make heavy qualitative brick commonly, its appearance has standard regulation, when also can be being cut according to needing to build, machine temporarily.
Light qualitative brick and heavy qualitative brick basically distinguish have the following:
1. Heat preservation function
The coefficient of thermal conductivity of light qualitative brick is in commonly 0.2-0.4(average temperature 25 ℃ of 350 ± ) W/m.k, and the coefficient of thermal conductivity of heavy qualitative brick 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 light qualitative brick wants specific gravity qualitative brick from this is good.
2. Fireproof degree
Of light qualitative brick fireproof degree be in 1400 degrees commonly the following, and those who weigh qualitative brick is fireproof degree in 1400 degrees of above.
3. Density
Light qualitative brick is light qualitative insulation material commonly, the density that density weighs qualitative brick in 0.8-1.0g/cm3 commonly is in basically 2.0g/cm3 above.
Integrated for, the mechanical intensity of heavy qualitative brick 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,
Fluid is enraged dispersedly since, prop up, the action that enclothe and protects activator. The hot-blast stove that also can be used at steely industry and heat in shift device.
Heavy qualitative brick has density big, intensity is high, wear-resisting, corrosion resistance can be good, hot coefficient of expansion is small, abrade efficiency is tall, noise is low, service life is long, do not touch contamination makings to wait for an advantage. It is the high quality abrade medium that suits to fetters at all sorts of muller.
The distinction of heavy qualitative brick and light qualitative brick is very big, their use environment, limits, function is not same. Different position can use different data, when material of choose and buy, we want the real case according to oneself, decide those who use to use which kinds of fireproof material to suit his.
