Iindidi ezahlukeneyo zee-castables zingahlulwa njengee-castables ezikhaphukhaphu, kuxhomekeke kulwakhiwo lwazo kunye neempawu ezithile. Eminye imizekelo eqhelekileyo ibandakanya:
1. Izinto zokukhusela ii-castables: Ezi zixhobo zokugquma zenzelwe ikakhulu iimpawu zazo ezibalaseleyo zokukhusela. Zinobunzima obuphantsi kunye nokuxinana okuphezulu, okufezekiswa ngokufaka ii-aggregates ezilula ezifana ne-perlite ekhulisiweyo, i-vermiculite, okanye iifayibha ezirhabaxa ezilula.
2. Iikhasta ezinoxinano oluphantsiEzi zixhobo zokuphosa zenziwe ukuba zibe noxinano oluphantsi ngelixa zinika amandla afanelekileyo oomatshini. Zihlala ziqulathe izinto ezilula ezifana ii-cenospheres, i-chamotte ekhaphukhaphu, okanye i-mullite ekhaphukhaphu. Ukudibana kwezi zinto zikhaphukhaphu kunye nezinto ezibophayo kubangela ukuba kubekho izinto ezikhaphukhaphu ezinobunzima obuphantsi.
3. Izinto zokuphosa ezinegwebu: Izinto ezifakwa kwi-foam zenziwa ngokufaka i-arhente evelisa i-foam kumxube ofakwa kwi-castable, nto leyo eyenza isakhiwo se-cellular xa somile kwaye sitsha. Esi sakhiwo se-cellular sinegalelo ekuxineni okuphantsi kunye neempawu zokufudumala eziphuculweyo. Izinto ezifakwa kwi-foam zihlala ziqulathe izinto ezikhaphukhaphu kunye nezinto ezifakwa kwi-foam.
4. Izinto ezisetyenziswa kwiVermiculite: I-Vermiculite yiminerali yendalo eyandayo xa ishushu. Ii-Vermiculite castables ziquka ii-vermiculite aggregates ezandisiweyo, ezinegalelo ekuxineni okuphantsi kunye neempawu ezilungileyo zokugquma. Ezi castables zifanelekile kwiindlela zokusetyenziswa kubushushu obuphakathi.
5. Izinto zokuphosa ze-alumina zebhamuza: I-Bubble alumina yi-aggregate ekhaphukhaphu, enemingxuma eveliswa ngokufudumeza uhlobo olukhethekileyo lwe-alumina ukuya kubushushu obuphezulu, nto leyo ebangela amaqamza egesi ngaphakathi kwento. Ii-Bubble alumina castables zikhaphukhaphu kwaye zineempawu ezilungileyo zokuthintela ubushushu, nto leyo ezenza zifaneleke ukusetyenziswa kubushushu obuphezulu.
Kubalulekile ukuqaphela ukuba ulwakhiwo oluthile kunye nohlu lwee-castables ezikhaphukhaphu zinokuhluka phakathi kwabavelisi kwaye zinokulungiswa ngokwezicelo ezithile. Ke ngoko, kucetyiswa rhoqo ukuba udibane nabathengisi okanye abavelisi abangafuniyo ukuze kuchongwe eyona i-castable ekhaphukhaphu ifanelekileyo kwiprojekthi ethile okanye kwimeko yokusetyenziswa.
