Isitena somlilo esikhanyayo esilula sisetyenziswa ngokubanzi kwinkqubo yokugquma kwee-kilns. Ukusetyenziswa kwezitena zomlilo ezilula kunye ne-lightweight kuzuze imiphumo ethile yokugcina amandla kunye nokukhusela okusingqongileyo kwishishini lobushushu obuphezulu.
Isitena somlilo esilulayo sisixhobo sokugquma esinobuninzi obuphantsi, i-porosity ephezulu, kunye ne-thermal conductivity ephantsi. Iimpawu zayo zoxinaniso oluphantsi kunye ne-thermal conductivity ephantsi yenza ukuba ingabinakuphinda ithathelwe indawo kwi-industrial kilns.
Inkqubo yemveliso yeisitena somlilo esikhanyayo esilula
1. Yenza umlinganiselo wezinto eziluhlaza ngokomlinganiselo ofunekayo, ugaye yonke into ibe ngumgubo. Yongeza amanzi kwisanti ye-silica ukwenza i-slurry kwaye uyifudumeze ngaphambi kobushushu obuyi-45-50 ℃;
2. Yongeza izinto eziseleyo eziluhlaza kwi-slurry kwaye uvuselele. Emva kokuxuba okupheleleyo, galela i-slurry edibeneyo kwi-mold kwaye uyitshise ukuya kwi-65-70 ° C ukuze igwebe. Isixa sogwebu sikhulu kune-40% yemali iyonke. Emva kokuba igwebu, yigcine kwi-40 ° C ngeeyure ezi-2.
3. Emva kokuma ngxi, ngena kwigumbi lokutshisa i-steaming, kunye noxinzelelo lwe-steaming ye-1.2MPa, iqondo lokushisa elitshisayo le-190 ℃, kunye nexesha le-9 iiyure;
4. Iqondo lobushushu eliphezulu sintering, ubushushu 800 ℃.
