Ingcaciso emfutshane

I-Tabular Alumina yimathiriyeli ecocekileyo efakwe kumaqondo obushushu aphezulu ngaphandle kwe-MgO kunye ne-B2O3 izongezo, i-microstructure yayo yi-polycrystalline ene-dimensional structure ene-tabular enkulu ekhuliswe kakuhle α - Al2O3 crystals. I-Tabular Alumina ine-pores encinci evaliweyo kwi-crystal ye-individval, umxholo we-Al2O3 ungaphezulu kwe-99% .Ngoko ke inozinzo oluhle lwevolumu kunye nokumelana nokutshatyalaliswa kwe-thermal, ukucoceka okuphezulu kunye nokuchasana, amandla agqwesileyo omatshini, ukuxhathisa i-abrasion ngokumelene ne-slag kunye nezinye izinto.

Itheyibhile kunye nezinye iiAggregates

Ii-aggregates zingumqolo we-refractory formulation kwaye zibonelela ngozinzo lwe-dimensional kwiimveliso eziphikisayo. Amaqhezu anqabileyo ongeza ukothuka kwe-thermal kunye nokuxhathisa ukubola kwaye izohlwayo ezidibeneyo ziphucula ukusabalalisa ubungakanani beqhekeza kunye nokwandisa ukuchasana kwemveliso.

Umgangatho ohambelanayo we-alumina ye-Tabular yisiphumo senkqubo ye-sinter elawulwa kakuhle kunye namaqondo okushisa omlilo ngaphezu kwe-1800 ° C. Ukusetyenziswa kwezithando zokushisa eziphezulu kunye nobuchwepheshe bezobugcisa buvumela ukuxinaniswa kwezinto ezikhethiweyo ezikhethiweyo ngaphandle kokuncedisa i-sintering aid. impembelelo embi kwiipropati zokushisa eziphezulu ze-refractories.

Njengomphumo wenkqubo ye-sinter, i-aggregates ibonisa ukubunjwa okufanayo kwe-mineralogical kunye neekhemikhali kuwo onke amaqhezu. Ngokuchasene neemveliso ezidityanisiweyo apho ukungcola kuqokelelwa kwisohlwayo, ukusetyenziswa kwe-sintered aggregates kwi-refractory formulation iqinisekisa ukuziphatha okuzinzileyo nokuthembekileyo.

I-Junsheng ibonelela ngeesayithi ezahlukeneyo zeeaggregates ukusuka kumaqhezu arhabaxa kakhulu ukuya kubungakanani bomhlaba ocolekileyo we <45 μm kunye <20 μm. Ukutyumza kunye nokusila kulandelwa ngamanyathelo oku-de-ayina okunzulu okukhokelela kwi-iron ephantsi kakhulu phakathi kwamaqhezu ahlukeneyo.

Ukusetyenziswa kweTabular Alumina

I-Tabular Alumina yimathiriyeli ekhethwayo kwii-refractories eziphezulu ezingasebenziyo ezisetyenziswa kumashishini ahlukeneyo aquka intsimbi, isiseko, i-samente, iglasi, i-protrochemical, i-ceramic, kunye nokutshisa inkunkuma. Ezinye izicelo eziqhelekileyo ezingezizo ezinqandayo ziquka ukusetyenziswa kwayo kwifenitshala ye-kiln kunye nokucoca isinyithi.
