Mo Laishi gets together light brick manage changes target

Mo Laishi gets together light brick has effect of favorable heat preservation heat insolation, system is secret little weight is light also be one of its characteristic, this product is fireproof stability of degree of tall, thermal shock good, coefficient of thermal conductivity is low and characteristic, come with it at present build by laying bricks or stones builds heat-insulation layer of liner of furnace of high temperature kiln, can remove good energy-saving thermal insulation.


JM26 Mo Laishi gets together light brick Mo Laishi pledges heat preservation brick uses high quality high pure and fireproof data gently, press product demand proportion, join organic and compound filler, via vacuum extrusion, high temperature burns the product of light qualitative Mo Laishi that combines. Pledge gently by right of its and the characteristic with heat preservation superior performance, the hot side that Mo Laishi pledges heat preservation brick applies extensively at a variety of hot project facilities gently is fireproof line or heat-insulation layer, create a condition to raise the energy utilization rate of equipment, with not coming the tall aluminium of Shi Zhujing photograph pledges fireproof material, general alumina content is between 65%-75% . Mo Laishi pledges fireproof temperature can achieve the brick gently 1790 ℃ above. Loading bate begins temperature 1600-1700 ℃ . Normal temperature compression spends 70-260MPa gently. Heatproof shake sex is good. Have agglomeration Mo Laishi brick and electric frit Mo Laishi brick two kinds. Agglomeration not comes stone brick is main raw material with tall aluminous aluminous grog, join a few clay or unripe alumina to make bond, via shaping, firing and make. Electric frit not comes stone brick is raw material with alumina of tall aluminous alumina, industry and fireproof clay, join charcoal or coke granule to do reducer, law of reductive report frit is used to make after shaping. The crystallization of electric frit Mo Laishi is bigger than agglomeration Mo Laishi, heatproof shake sex is better than agglomeration goods. Their high temperature capability basically depends on the uniformity that the content of alumina and glass of Mo Laishi get along with distributing.

Roller path kiln gets together with Molaishi one of crucial factors that the heat preservation effect of the furnace of kiln of energy-saving effect industry of brick of light heat preservation is effect specific power consumption. Develop a kind of service life to grow and the product that can reduce quality of body of heater is to have very much want. JM28 belongs to Molaishi to combine material, have high temperature capability the characteristic with good, low cost, can use at kiln furnace liner, can reduce body of heater effectively not only quality, managing light, still can prolong lining service life, reduce uphold charge. 1, JM28 Mo Laishi gets together the Molaishi that Cheng Naicai of the flourish of brick of light heat preservation that make produces gets together brick of light heat preservation with industrial AL2O3 pink, clay, agglomeration good aluminous alumina and partial cyanite are given priority to should, add wood chip (1mm is chosen) beg with polystyrene (diametical 2~0.5mm) preparation pledges gently brick. In joining fine white of industrial AL2O3 pink, aluminous, cyanite, clay mixer first, work mix 3~5min, add polystyrene ball, wood chip and bond next (adscititious) , edge border agitate, after mixing even, go out grind. Use crowded mud law to shape. After 48h of ℃ of 50~60 of wet base course and 100~110 ℃ 72h are dry after shaping firing. Firing temperature control is in 1400~1500 ℃ , heat preservation 8h. The exterior that checks sample according to relative standard check and manage change target. 2, result and the JM28 Mo Laishi that analytic flourish Cheng Naicai produces get together exterior of finished product of brick of light heat preservation is white, edges and corners trenchant, size is exact. Its manage changes index to be: AL2O3=67.99% , fe2O3=0.87% , is bulk density 0.8g/cm? , compression intensity is 2.3MPa, change of the line after 1500 ℃ 8h is burned is - 0.1% , thermal conductance (800 ℃ ) for K-1 of · of 0.24W · M-1. Turn index result according to manage knowable: Content of AL2O3 of finished product of light qualitative brick is 67.99% , explain this matchs more than generating Molaishi: Fe2O3 content <1% , exterior of the adobe after be being burned so is white (if iron content on the high side, the adobe after burning is aglow) . Compression intensity satisfies a standard to ask (≥ 2.1MPa) , because industrial AL2O3 is in,be firing 13% bulk systole of the left and right sides arose in the process, those who be helpful for compression intensity rise. Clay and industrial AL2O3 are in firing the bulk that different level appeared in the process is contractive, and aluminous Molaishi changes generation bulk to expand, of cyanite decompose reaction to also produce bulk to expand, systematic bulk expands and systole offsets each other make change of product whole line not big, change of the line after 1500 ℃ 8h burns is only - 0.1% : Thermal conductance (800 ℃ ) for K-1 of · of 0.248W · M-1, because the experiment is medium,basically be arose after added wood chip and polystyrene spherule are firing even small 7 aperture, constituent structure is even, thermal conductance is low, achieved energy-saving result. 3, the applied JM28 Mo Laishi of the product gets together the liner of job of shuttle type kiln that brick of light heat preservation applies at ceramics works, 1400 ℃ control normal use temperature, high temperature resistant function of function, heat conduction function, accumulation of heat all compares cite data advantageous and service life is long, improved the quality of the product and productivity, improved working environment. Use JM28 Mo Laishi to get together the air consumption of every kiln after brick of light heat preservation is working line is controlled for 160Kg, mix a structure than former brick every kiln but managing light 40Kg left and right sides, energy-saving advantage is clear. 4, conclusion JM28 Mo Laishi gets together brick of light heat preservation has bulk stability intensity of good, compression tall, thermal conductance is small waited for an advantage to achieve managing light gas and the goal that reduce kiln style quality. About not coming manage of Shi Ju light brick changes index to introduce here, hope to be helped somewhat to everybody, flourish Cheng Naicai regards professional firebrick as manufacturer, have perfect quality be careful in one's conduct to mark allows and monitor a system, the formula of check proved recipe that Rong Chengcai uses pair of 3 check, strict self check, sampling observation, reinspect a program, ensure each batches of fireproof material can accord with the standard of the user, let what the client buys be at ease used Shu Xin.
