Njengenxalenye ebalulekileyo yecandelo lokukhusela ukuguguleka kwemizi-mveliso, ukumelana nobushushu obuphezulu kweeseramikhi ezinganyangekiyo bekusoloko kuyinxalenye ebalulekileyo yoqwalaselo lomntu wonke. Ingakumbi kwezinye iimeko zokusebenza ezinotshintsho olukhulu lobushushu okanye ubushushu obuphezulu, ukukhetha uhlobo olufanelekileyo lweeseramikhi ezinganyangekiyo kunye nendlela efanelekileyo yokufakela kubaluleke kakhulu kwimveliso ekhuselekileyo kunye nokonga amandla kunye nokusebenza kakuhle. Ngoko ke zeziphi izinto eziphambili ezichaphazela ukumelana nobushushu obuphezulu kweeseramikhi ezinganyangekiyo?
1. Ubunyulu bezinto zeseramikhi ezinganyangekiyo: Iiseramikhi ezinganyangekiyo esihlala sithetha ngazo zibhekisa kakhulu kwiiseramikhi ezinganyangekiyo ze-alumina, kwaye ubunyulu be-alumina bunempembelelo ngqo kubushushu obuphezulu beeseramikhi ezinganyangekiyo. Iiseramikhi ezinganyangekiyo ze-alumina zitshiswa kubushushu obuphezulu be-1700°C kwaye zinobunyulu obuphezulu obuphezulu. Nangona kunjalo, kwizicelo ezisebenzayo, ukuba ubunyulu be-alumina abuphezulu, iiseramikhi ziya kuba nezinye izinto. Ezi zinto ziya kubonisa iipropati ezahlukeneyo zokwanda kobushushu kunye nokuncitshiswa kubushushu obuphezulu okanye ukupholisa ngequbuliso kunye nokufudumeza ngenxa yeempawu ezahlukeneyo. Le meko ayicacanga xa ubushushu butshintsha kancinci okanye uluhlu lotshintsho luncinci, kodwa xa ubushushu butshintsha kakhulu okanye budibana nobushushu obuphezulu be-800, 900 okanye ne-1,000 degrees, olu tshintsho luya kuba nempembelelo enkulu, kwaye iiseramikhi ezinyulu kufuneka zikhethwe.
2. Indlela yokufaka: Indlela yokufaka iiseramikhi ezinganyangekiyo ikwanefuthe elithe ngqo kubushushu obuphezulu beeseramikhi. Umzekelo, xa kusetyenziswa iglu eqhelekileyo yeseramikhi ukuncamathisela iiseramikhi, ubushushu obuphezulu enokumelana nabo bumalunga ne-150°C. Iglu yobushushu obuphezulu inokunyusa obu bushushu bube yi-200°C, kodwa xa ubushushu obuphezulu beglu budlulile, i-viscosity yeglu iya kuchaphazeleka, nto leyo enokubangela ukuba iseramikhi iwe ngokulula. Xa kuthelekiswa nendlela yokuncamathisela, iiseramikhi ezifakwe yindlela yokuwelda yestud kunye ne-dovetail slot zinokumelana nobushushu obuphezulu be-750°C. Umbhobho weseramikhi onganyangekiyo owenziwe ngokudibeneyo unokunciphisa kakhulu umda wendlela yokufaka kubushushu obuphezulu beeseramikhi.
3. Izinto ezidityaniswe neeseramikhi: Iiseramikhi zihlala zisetyenziswa kunye nezinye izinto, ezifana neentsimbi, irabha, njl. Kwimeko enjalo, xa sigweba ukumelana nobushushu obuphezulu kweeseramikhi ezingagugiyo, kufuneka siqwalasele ukumelana nobushushu kwezinto ezidityanisiweyo. Umzekelo, izinto ezidityanisiweyo zeseramikhi-irabha azifanelekanga ukusetyenziswa kwiimeko zobushushu obuphezulu.
Ngamafutshane, kukho izinto ezintathu eziphambili ezichaphazela ukumelana nobushushu obuphezulu kweeseramikhi ezinganyangekiyo, ngoko ke ezi zinto kufuneka ziqwalaselwe ngokupheleleyo xa kukhethwa iiseramikhi ezinganyangekiyo.
