I-Light Weight Clay Insulation Brick yenziwe nge-fire clay grog njengempahla eluhlaza kanye nobumba lwepulasitiki njenge-ejenti ebophayo bese yengeza i-ejenti evuthayo evuthayo noma egwazayo ngokudubula. amabhlogo okuvikela ubumba okubonakalayo ukuthi i-porosity iphezulu cishe ngo-40~85% futhi ukuminyana ngobuningi kungaphansi kuka-1.5 g/cm3. Izitini zomlilo ze-clay insulation zisetshenziswa kakhulu njengezinto zokufakelwa kuhhavini lezimboni ukunciphisa ukulahlekelwa ukushisa kweziko, zonga amandla futhi zikhanyise ikhwalithi yemishini eshisayo.
I-Light Weight Clay Insulation Brick ikhiqizwa ngobumba obuhlanzekile bomlilo obuphezulu kanye ne-binder, ngokucwilisa ngokusebenzisa izinga lokushisa eliphezulu. amabhulokhi okufakwa ubumba yizitini zokufakelwa kwe-refractory ezibiza kancane ezisebenza kahle kakhulu. Izinzuzo eziyinhloko ze-block insulation block yi-refractoriness ephezulu ngaphansi komthwalo, ama-coefficients okwandisa umugqa ophansi, ukumelana nokushaqeka okuhle kokushisa kanye nekhono eliqinile lokumelana nokuguguleka. Okwakhiwa ngezinto zokwakha ze-fireclay ezisezingeni eliphezulu ngaphansi kwezinga lokushisa eliphakeme ngokwezinga elihlala njalo likazwelonke, elinobuningi obukhulu, amandla aphezulu, ukuqhutshwa kokushisa okuphansi kanye nokungcola okuphansi.
I-clay insulation firebrick ingumkhiqizo we-argillaceous onokuqukethwe okungaba ngu-30~40% we-Al2O3. eyenziwe ngobumba obuthambile obungama-50% kanye ne-chamotte eqinile engu-50% ngokusho kwe-granularity ethile okudingeka ihlanganiswe futhi ixoshwe ku-1300 ~ 1400 ℃ izinga lokushisa eliphakeme ngemva kokubunjwa nokomiswa. Isitini somlilo esifakwa ubumba esiyinhloko samaminerali ahlanganisa i-kaolinite (Al2O3 · 2SiO2 · 2H2O) kanye nokungcola okungu-6~7% (K, Na, Ca, Ti, Fe oxide).

I-clay insulation block isetshenziselwa ikakhulukazi ulwelwesi oluvikelayo lwezindawo ezishisayo noma ukusekela izendlalelo zokuvikela ukushisa kwezinye izinto eziphikisayo. Izintambo eziphikisayo noma izinto zokuvikela ukushisa ezimbonini, ezifana nezithando ze-ethylene pyrolysis, izithando zamashubhu, iziko elilungisa kabusha i-ammonia yokwenziwa, amajeneretha egesi kanye neziko lokushisa eliphakeme le-shullte, njll.
