Calcined Alumina Ultrafine For High-Performance Refractories

I-calcined alumina powders yenziwa ngokubala ngokuthe ngqo kwe-alumina yoshishino okanye i-aluminium hydroxide kumaqondo okushisa afanelekileyo ukuguqula i-crystallineα-alumina ezinzileyo, emva koko igaye ibe yi-micro-powders. Umgubo ocoliweyo omncinci ungasetyenziswa kwisango lesilayidi, imilomo, kunye nezitena zealumina. Ukongeza, zinokusetyenziswa kwii-castables kunye ne-silica fume kunye ne-alumina powders esebenzayo, ukunciphisa ukongezwa kwamanzi, i-porosity kunye nokwandisa amandla, ukuzinza kwevolumu.

Iimveliso ze-alumina ezinomgubo we-alumina we-calcined njengezinto ezikrwada zinamandla abalaseleyo omatshini, ukuqina okuphezulu, ukuxhathisa kombane okuphezulu kunye nokuhamba kakuhle kwe-thermal. I-aluminium calcined micropowder ingasetyenziswa ngokubanzi kwizixhobo zombane, iiseramikhi zesakhiwo, iirefractories, i-abrasives, imathiriyeli yokugulisa, njl.

Iialuminas ezibaliweyo ziialpha-aluminas ezibandakanya ubukhulu becala iiagglomerate ze-sintered zeekristale zealumina. Ubungakanani bezi crystals eziphambili buxhomekeke kwiqondo lokubala kunye nobungakanani beagglomerate kumanyathelo okusila alandelayo. Uninzi lwe-aluminas e-calcined lunikezelwa umhlaba (<63μm) okanye umhlaba ococekileyo (<45μm). I-agglomerates ayichithwanga ngokupheleleyo ngexesha lokusila, nto leyo ebaluleke kakhulu kwi-aluminas esebenzayo ephantsi ngokupheleleyo yinkqubo yokugaya ibhetshi. I-aluminas e-calcined ihlelwa ngumxholo we-soda, ubungakanani be-particle size kunye neqondo lokubala. I-aluminas e-calcined ephantsi kunye neyomhlaba ocolekileyo isetyenziswa njenge-matrix filler ukuphucula ukusebenza kwemveliso yokwakheka okusekwe ikakhulu kwimathiriyeli ekrwada yendalo.

I-aluminas ene-calcined inobungakanani bamasuntswana afana nee-aggregates zeminerali ephantsi kwaye ngoko ke ziyakwazi ukuthatha indawo ye-aggregates ngokucoceka okuphantsi. Ngokunyusa umxholo we-alumina jikelele wemixube kunye nokuphucula ukupakishwa kwe-particle yabo ngokudibanisa i-alumina emihle, i-refractoriness kunye neempawu zemishini, ezifana ne-modulus eshushu yokuqhaqha kunye nokuxhatshazwa kwe-abrasion, ziphuculwe. Imfuno yamanzi ye-aluminas e-calcined ichazwa ngumlinganiselo wee-agglomerates ezishiyekileyo kunye nommandla ongaphezulu. Ngoko ke, i-aluminas e-calcined kunye nommandla ophantsi ophantsi zikhethwa njengezizaliso kwizitena kunye ne-castables. Iialumina ezikhethekileyo ezibaliweyo ezinommandla ongaphezulu, zinokuthatha indawo yodongwe ngempumelelo njengeplastiki kwimipu kunye nemixube yeramming. Iimveliso ezichasayo eziguqulwe zezi mveliso zigcina iimpawu zazo ezilungileyo zokufakela kodwa zibonisa ukunciphisa kakhulu emva kokumisa kunye nokudubula.

Ii-Aluminas ezineCalcined for Refractories

Ngenxa yeempawu ezibalaseleyo zobushushu obuphezulu be-a-Alumina, ii-Aluminas eziCalcined zisetyenziswa kwizicelo ezininzi eziphikisayo, zombini kwimveliso ye-monolithic kunye nemilo.

Ukusebenza kweMveliso
Ngokuxhomekeke kwiqondo lokusila kunye nobukhulu bekristale, ii-Aluminas zeCalcined zisebenza ngeendlela ezahlukeneyo kwiifom ze-refractory.

Okona kubalulekileyo zezi:
• Ukuphucula ukusebenza kwemveliso ngokunyusa isiqulatho se-Alumina xa sisonke kolu qulunqo kusetyenziswa imathiriyeli ekrwada yendalo ukuze kuphuculwe i-refractoriness kunye neempawu zoomatshini.
• Ukuphucula ukupakishwa kwamasuntswana ngokunyusa umthamo wamasuntswana amahle okukhokelela kumandla omatshini angcono kunye nokuxhathisa kwe-abrasion.
• Yenza imatriki yokuchasa okuphezulu kunye nokumelana nokothuka kwe-thermal ngokusabela ngezinto zokubopha njengeCalcium Aluminate Cement kunye / okanye udongwe.
