Brick of a few commonly used kinds of light qualitative heat preservation

One, brick of heat insolation of light qualitative clay

 

Is light qualitative sticky earthy and adiabatic brick the Al2O3 content that controls for main raw material with fireproof clay for 30% ? The adiabatic and refractory products of 48% . Its produce craft to use burn oneself out to add content law and bubble way. With fireproof clay, float bead, fireproof clay grog makes raw material, mix into is added bond and curium wood chip, classics burden, mix, figuration, dry, firing is ’ made so that bulk density is 0.3? The product of 1.5g/cm3. The crop of light qualitative sticky earthy and adiabatic brick occupies the half above of adiabatic firebrick total output.

2, diatomite pledges gently heat preservation brick (adiabatic brick)

 

(1) this product is main raw material with high grade diatomite, wood chip and high temperature binder, via mixing, crowded base shapes, dry hind agglomeration and into.

 

(2) because a large number of small hole are contained in goods, it and clay are qualitative, tall aluminium is qualitative, float bead pledge and fiber kind adiabatic goods photograph is compared, have compressive strength tall, bulk density is low, coefficient of thermal conductivity is small, have unit weight light, construction safety is convenient, heat preservation is energy-saving the effect is good wait for an advantage with cheap of qualitative actor price. Performance of revulsion of furnace temperature of resistance of 1100 ℃ less than is good, when revulsion of difference in temperature not craze, changeless form.

 

(3) heat preservation of secondary floor of body of the thermal insulation of equipment of air channel of wall of the electrobath of the industry such as heat preservation of furnace of kiln of electric power, metallurgy, oil, chemical industry, cement, pottery and porcelain, spin, glass, light industrial, coloured, conduit, furnace, high fever, high temperature, wall, adiabatic, soundproof ideal material; It can raise temperature not only, shorten heat time, can reduce specific fuel consumption, achieve heat preservation energy-saving effect.

 

3, brick of heat preservation of light qualitative Mo Laishi

 

(1) heat preservation brick has light qualitative Molaishi expand stability of even, thermal shock creep of tall, high temperature is worth softening point of wonderful, loading small, hardness is big, fight chemistry caustic good wait for a characteristic. The different and main component of brick of light qualitative heat preservation according to density is Mo Laishi to be mixed gently character pledge again. What use temperature according to its is different, model can be divided for series of MG-23, MG-25, MG-26, MG-27, MG-28, MG-30, MG-32 7 kinds.

 

(2) one of very important members in pledging brick of Mo Laishi heat preservation is heat preservation brick gently, this kind of product can contact blaze directly (very important characteristic) , have spend tall, coefficient of thermal conductivity high temperature resistantly, gently small, energy-saving effect is distinct wait for a characteristic, apply to crucible of kiln of drawer of porcelain of kiln of path of roller of splitting decomposition furnace, hot-blast stove, pottery and porcelain, report, glass and the liner of all sorts of electric stove.

 

4, alumina is hollow ball brick

 

(1) alumina pink is to choose high grade industry alumina to be raw material, use new-style high temperature to pour blaze kiln and production of scientific to calcine craft, it is artificial concentration, clear to classification, contain impurity little, change it is good to lead stability of tall, shrinkage, consistency.

 

(2) alumina is hollow ball brick is a kind of new-style high temperature heat-insulating material, highest use temperature 1800 ℃ , products machinery intensity is high, those who be general small qualitative products is multiple, and 1/2 what bulk density is corundum goods only.

 

(3) hollow ball brick applies alumina extensively on furnace of the high temperature such as electric induction furnace of reaction furnace of industry of furnace of petrifaction industry aerification, carbon black, metallurgical industry, superhigh temperature kiln, and obtained first-rate energy-saving result.

 

5, tall aluminium gets together light brick

 

(1) tall aluminium gets together brick of a light brick is series of light qualitative tall aluminous brick new-style heat preservation heat insolation, basically use tall aluminium clinker and high pure clay, with fill of polystyrene bubble ball, classics is firing light make. Have raw material purity even, low heat conduction leads structure of tall, aperture, low thermal capacitance, intensity is high, dimension precision is advanced characteristic.

 

(2) tall aluminium gets together light brick says tall aluminium gets together again light ball brick, have compression strength tall, thermal shock stability is good, can reduce the thermal capacity of boiler setting, improve the thermal efficiency of kiln furnace.

 

(3) tall aluminium gets together the application of light brick: The kiln furnace liner that applies at the industry such as metallurgy, mechanical, pottery and porcelain, chemical industry (do not suffer solution to erode) reach heat-insulation layer, it is a kind of good energy-saving product. Use temperature is under 1350°C.

 

6, brick of light qualitative clay

 

(1) brick of light qualitative clay belongs to air hole kind light qualitative insulation material, al2O3 content is in 30%-46% . Mix with fireproof clay or light qualitative grog but model clay is main raw material.

 

(2) porosity of brick of light qualitative clay is tall, amount to 40%~85% commonly. Low heat conduction is led, low thermal capacitance.

 

(3) brick of light qualitative clay uses the adiabatic segment in industrial kiln furnace commonly according to its function characteristic, can reduce furnace kiln heat loss due to radiation, economic energy resources is used up, can reduce the quality of hot project facilities. Also use at sufferring the kiln furnace liner that stock of high temperature melt and aggressivity gas institute erode sometimes. Highest use temperature is in 1500 ℃ of 1200 ～ . Sex of caustic of the mechanical intensity of brick of light qualitative clay, wear-resisting and the aggressivity that fight broken bits is poorer, unfavorable at kiln furnace bearing structure and direct contact the place such as metal of slaggy, charging, melt.

 

7, brick of qualitative heat insolation of light qualitative silicon

 

Light qualitative silicon pledges adiabatic brick is the SiO2 content that controls for main raw material with silica do not be less than the adiabatic and refractory products of 91% . Is the bulk density of qualitative adiabatic brick light qualitative silicon 0.9? 1.1g/cm3, thermal conductance has the in part of common silica brick only, heatproof brace up the gender is good, its loading bate begins temperature to be able to amount to 1600 ℃ , brick of outclass clay qualitative heat insolation. Consequently highest use temperature can amount to brick of silicon qualitative heat insolation 1550 ℃ . Not contractive below high temperature, still have even expand faintly.
