0 expand what meaning is silica brick?

0 expand to silica brick calls melt quartz the brick again or fight thermal shock silica brick. Anxious furnace has extremely low heat coefficient of expansion, admirable be able to bear or endure advanced characteristic of content of strength of urgent cold urgent hot sex, good high temperature structure, SiO2. Among the project of fast hot rehabilitate that this product can use extensively at all sorts of anxious furnace, this product does not produce crackle to flake when use phenomenon, be close to the low heat of 0 to expand function, after making Jiao Luxiu fills, use on the safe side for a long time.


0 expand silica brick is characteristic 1. SiO2 content is more than 99% , fight erode, acid-proof sex is exceedingly good 2. Low Fe2O3 content is less than 0.1% , to goods (wait like vitreous fluid) free from contamination 3. Low flux index (Al2O3+2R2O) be less than 0.3%4. Heat expands rate is adjacent Yu Ling, when repairing but need not obligate expands seam, the close sex that increases build by laying bricks or stones to build system 5. Excellent thermal stability, the goods when heat is repaired won't produce scamper to crack, can fall in the high temperature circumstance of ceaseless furnace, undertake revamping operation directly 6. Repair (heat is repaired) hind, won't happen flake wait for a phenomenon, use on the safe side for a long time
0 expand what meaning is silica brick? With silica brick silica brick of difference having what is had fight acid slag to erode performance. Higher high temperature intensity. Loading bate begins temperature 1670 ℃ of 1620 ～ . Use changeless form for a long time below high temperature. Thermal shock stability is low (hot exchange is 1~4 in water second) it is raw material with natural silica, adscititious and right amount mineralizer, in order to promote the quartz in base substrate quartz of translate into phosphor. In the classics below reducing atmosphere ℃ of 1350 ～ 14 30 is slow and firing. Heat to expand to the total volume that there is hundred 1.5~2.2 about when 1450 ℃ , this kind of remains expands can make cut seam join closely, make sure build by laying bricks or stones builds body to have good air-tightness and structural strength. Have service life to grow at the same time, reduce specific power consumption to wait for an advantage. 0 expand of silica brick expand to be almost 0, common silica brick can appear expand, two kinds price has a difference.
Use the account that brick of hearth of room of char of client of case cooking factory damages, adopt use below temperature of 850 ℃ above 0 expand the plan that silica brick revamps hearth brick, solved the difficult problem that brick of char room bottom repairs, obtain hot condition to repair successful effect.
The fireproof material that Rong Cheng fact regards major as produces manufacturer to be able to produce the product of fireproof heat preservation of a variety of different types, product type basically undertakes classified from material character with construction means, the line of the products that my factory produces is all ready, OK and contented show level what the place of hot project facilities such as furnace of kiln of all sorts of power plant boiler, industry needs is high temperature resistant requirement, product quality is worth your reliance.
