I-Refractory Castable
Ingcaciso yeMveliso
Izinto zokuphosa ezirhabaxazingumxube wee-aggregates ezichasayo, iipowders kunye nee-binders. Emva kokongeza amanzi okanye ezinye izinto ezimanzi, zifanelekile ukwakhiwa ngeendlela zokugalela kunye nokungcangcazela. Zingalungiswa zibe ziinxalenye ezilungiselelwe kwangaphambili ezineemilo kunye nobukhulu obuthile bokwakha ii-linings ze-furnace zemizi-mveliso. Ukuze kuphuculwe iipropati zomzimba nezekhemikhali kunye nokusebenza kokwakhiwa kwee-castables ezichasayo, kudla ngokufakwa izixa ezifanelekileyo ze-admixtures, ezifana nee-plasticizers, ii-dispersants, ii-accelerators, ii-retarders, ii-expansion agents, ii-debonding-gelling agents, njl. Ukongeza, kwii-castables ezichasayo ezisetyenziswa kwiindawo ezineemandla ezinkulu zoomatshini okanye i-thermal shock enamandla, ukuba kongezwa isixa esifanelekileyo sefayibha yentsimbi engagqwaliyo, ukuqina kwezinto kuya kwanda kakhulu. Kwi-castable echasayo echasayo, ukuba kongezwa iifayibha ezingaphiliyo, ayinako nje kuphela ukomeleza ukuqina, kodwa ikwanceda ukuphucula iipropati zayo zokuthintela ubushushu. Ekubeni ukwakheka kwezinto ezisisiseko zezinto ezisetyenziswayo ezingafunekiyo (ezifana nee-aggregates kunye nee-powders, i-admixtures, i-binders kunye ne-admixtures), inkqubo yokuxinana kunye nokuqina, iindlela zokwakha, njl.njl., zifana nekhonkrithi kubunjineli bokwakha, yayikhe yabizwa ngokuba yiikhonkrithi enganyangekiyo.
