Njengenxalenye ebalulekileyo yecandelo lokukhusela ukunxitywa kwemizi-mveliso, ukumelana nobushushu obuphezuluiiseramikhi ze-aluminaibisoloko iyeyona nto iphambili kuye wonke umntu. Ingakumbi kwiimeko ezithile zokusebenza ezinotshintsho olukhulu lobushushu okanye ubushushu obuphezulu, ukukhetha uhlobo olufanelekileyo lweeseramikhi ezimelana nokuguguleka kunye nendlela efanelekileyo yokufaka kubaluleke kakhulu kwimveliso ekhuselekileyo kunye nokonga amandla kunye nokusebenza kakuhle. Ngoko ke zeziphi izinto eziphambili ezichaphazela ukumelana nobushushu obuphezulu kweeseramikhi ezimelana nokuguguleka?
1. Ubunyulu bezinto ze-alumina ceramics: Ii-ceramics ezingagugiyo esihlala sithetha ngazo zibhekisa kakhulu kwii-ceramics ezingagugiyo ze-alumina, kwaye ubunyulu be-alumina bunempembelelo ngqo kubushushu obuphezulu bee-ceramics ezingagugiyo. Ii-ceramics ezingagugiyo ze-alumina zitshiswa kubushushu obuphezulu be-1700°C kwaye zinobunyulu obuhle kakhulu kubushushu obuphezulu. Nangona kunjalo, kwizicelo zokwenyani, ukuba ubunyulu be-alumina abuphezulu, ii-ceramics ziya kuba nezinye izinto. Ezi zinto ziya kubonisa iipropati ezahlukeneyo zokwanda kobushushu kunye nokuqiniswa 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 kuyimfuneko ukukhetha ii-ceramics ezinobunyulu obuphezulu, njenge-Jingcheng's K99 alumina ceramics.
2. Indlela yokufaka: Indlela yokufaka iiseramikhi ezinganyangekiyo nazo zinefuthe ngqo ekuchaseni ubushushu obuphezulu beeseramikhi. Umzekelo, xa kusetyenziswa iglu eqhelekileyo yeseramikhi ukuncamathisela iiseramikhi, ubushushu obuphezulu enokumelana nabo bumalunga ne-150°C. Iglu ekhethekileyo yeseramikhi kaJingcheng inokunyusa obu bushushu bube yi-350°C, kodwa xa ubushushu obuphezulu beglu budlulile, i-viscosity yeglu iya kwehla kakhulu, nto leyo enokubangela ukuba iseramikhi iwe ngokulula. Xa kuthelekiswa nendlela yokuncamathisela, indlela yokuwelda yestud kunye neeseramikhi ezifakwe yi-dovetail slot zinokumelana nobushushu obuphezulu be-750°C. Umbhobho weseramikhi onganyangekiyo ohlanganisiweyo osandul’ ukuphuhliswa nokuveliswa yiJingcheng unokunciphisa kakhulu umda wendlela yokufaka ekuchaseni ubushushu 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 zerabha zeseramikhi azifanelekanga ukusetyenziswa kwiimeko zobushushu obuphezulu.
Ngamafutshane, kukho izinto ezintathu eziphambili ezichaphazela ukumelana nobushushu obuphezuluiiseramikhi ezingagugiyo, oko kukuthi ubumsulwa bezinto zeseramikhi ngokwazo, indlela yokufaka iiseramikhi, kunye nezinto ezidityaniswe neeseramikhi. Ezi zinto kufuneka ziqwalaselwe ngokupheleleyo xa kukhethwa iiseramikhi ezingagugiyo.
