Nxiba ii-linings ze-ceramic ezimelana nokunxitywaukusombulula ingxaki yokuguguleka kwimizi-mveliso egugulekayo efana nesamente, intsimbi, imigodi, iibhetri ze-lithium, kunye ne-metallurgy. Nangona kunjalo, xa zisetyenziswa ngokwenene, ezinye iifektri zikholelwa ukuba ii-linings ze-ceramic ezingagugiyo zibuthathaka kwaye azigugi. Ngoko ke singayiphucula njani i-insert ye-ceramic engagugiyo?
Izinto eziphambili ze-linings ze-ceramic ezinganyangekiyo esiqhele ukubhekisela kuzo yi-alumina, enobunzima bokuqhekeka obuyi-KΙC ≥4.8MPa•m1/2 kunye namandla okugoba ayi-≥290MPa. Xa kuthelekiswa nezinto zesinyithi ezifana nentsimbi, ukumelana nokuchaphazeleka kuphantsi ngokwenene, kodwa ngeenkqubo ezithile ezikhethekileyo, ukumelana nokuchaphazeleka kwe-linings ze-ceramic ezinganyangekiyo kunokuphuculwa kakhulu.
1. Uyilo lomphezulu we-spherical protrusions:
Iimpawu ezikhethekileyo zoomatshini zezi ngqokelela zinokusasaza ngokulinganayo amandla okuchaphazeleka kwi-lining, nto leyo enciphisa amathuba okuba i-lining iphuke ngenxa yokuchaphazeleka. Yindlela eqhelekileyo yokuphucula ukuxhathisa ukuchaphazeleka kwe-linings ze-ceramic ezingagugiyo.
2 Yandisa indawo yerabha yomphezulu: Iilayini zeseramikhi ezingagugiyo zisetyenziswa kakhulu xa zidibene nerabha. Ukumelana nempembelelo kweeseramikhi kubuthathaka, kodwa ukumelana nempembelelo kwerabha kunamandla kakhulu. Sinokunika ithuba elipheleleyo kwiingenelo zazo zombini, sisebenzisa iiseramikhi ukuxhathisa ukugugi kunye nerabha ukuxhathisa ukugugi. Indlela ethile yokusebenza kukuveza irabha engaphezulu kumphezulu welayini ngexesha lenkqubo ye-vulcanization, njengokushiya izithuba okanye ukusebenzisa iziqwenga zeseramikhi ezijikelezileyo. Kufuneka kuqatshelwe ukuba njengoko indawo yerabha kumphezulu welayini isanda, indawo yeseramikhi iya kuncipha. Ngelixa ukumelana nempembelelo kuphucuka, ukumelana nokugugi kuya kuncipha. Xa uyisebenzisa, kuyimfuneko ukuyiqwalasela ngokupheleleyo ngokweemeko zokusebenza zokwenyani.
3 Yongeza ezinye izinto eziluhlaza kwi-alumina ukuze kulungiswe ukuqina: I-Chemshun Ceramics Co., Ltd. izibophelele ekuveliseni nasekuphandeni nasekuphuhliseni iiseramikhi ezingagugiyo. Inxalenye ethile ye-zirconium oxide yongezwa kwizinto eziluhlaza ze-alumina ukuze kwenziwe iiseramikhi ezingagugiyo ze-alumina, ezinokuphucula kakhulu ukumelana nempembelelo kweeseramikhi ezingagugiyo. Ukumelana nempembelelo kweeseramikhi ezingagugiyo ze-alumina kubuthathaka ngokwenene, kodwa le ngxaki ingasombululwa ngoyilo oluyindilinga, irabha evulcanized, kunye nokongeza i-zirconium oxide, ukuze ii-ceramic liners ezingagugiyo zikwazi ukuziqhelanisa nobunzima obunzima kunye neemeko ezinamandla zempembelelo.
