Isithando Sokuhlikihla Amazinyo vs. Isithando Sokuhlikihla Se-Porcelain: Umhlahlandlela Ophelele Wezinto Ezisetshenziswayo, Inqubo, Nokuthenga Esifanele

Ngamazwi alula: amandla vs. ubuhle . Isithando somlilo esishisayo siqinisa i-zirconia sibe ukuvuselelwa okusebenzisekayo. Isithando somlilo se-porcelain sisenza sibukeke njengezinyo langempela. Amazinga okushisa ahlukene, imishini ehlukene, imisebenzi ehlukene - futhi akekho ongenza umsebenzi womunye.

Lo mhlahlandlela uchaza kahle ukuthi umshini ngamunye wenzani, ukuthi kungani ungenakushintshaniswa, nokuthi unganquma kanjani ukuthi iyiphi (noma iyiphi inhlanganisela) ilabhorethri yakho eyidingayo ngempela. Ekugcineni, uzokwazi ukuthi iyiphi iyunithi ephatha amandla esakhiwo nokuthi iyiphi ephatha umbala nokukhanya, ukuthi ungabhajetha kanjani ngokusekelwe ekutheni ilabhorethri yakho isebenzisa kakhulu imiqhele namabhuloho e-zirconia noma ikakhulukazi ama-veneer nama-ceramics anezingqimba, nokuthi yiziphi izici ezibaluleke ngempela uma uqhathanisa ama-furnace - ngale nje kokushisa okuphezulu eshidini le-spec.

Kungani Ama-Dental Lab Adinga Zombili Izinhlobo Zesithando Somlilo

I-zirconia coping esanda kuphuma emshinini wokugaya isathambile futhi ifana ne-chalk — ungayinqamula phakathi ngeminwe yakho. Iba yindlela yokuvuselela engasetshenziswa emtholampilo kuphela ngemva kokushisa okungaphezu kuka-1,400°C, inqubo ebizwa ngokuthi i-sintering, okuwumsebenzi wesithando sokushisa se-zirconia. Ukwenza lokho kulungiswa kubukeke njengezinyo lemvelo — umbala ofanele, ukukhanya okulungile — kuthatha esinye isinyathelo: ukwengeza i-porcelain, ukufaka idayi, kanye nokucwebezela esithandweni sokushisa se-porcelain, ngokuvamile kusebenza phakathi kuka-700–1,000°C.

Omunye umshini uphendula ngokuthi "ingabe izokuma?" Omunye uphendula athi "ingabe ibukeka kahle?" Leyo mibuzo emibili iphila emazingeni okushisa ahlukene ngokuphelele futhi idinga ihadiwe ehlukene ngokuphelele. Yingakho nje ungeke ubone uhlu lwemishini yelabhorethri yamazinyo lubheka lokhu njengokushintshisanayo.

Iyini i-Zirconia Sintering Furnace futhi isebenza kanjani?

Isithando somlilo esishisa i-zirconia sinomsebenzi owodwa: ukuhlanganisa izinhlayiya ze-zirconia ndawonye ngaphansi kokushisa okuphezulu okuqhubekayo ukuze ama-micro-pores angaphakathi anyamalale futhi izinto zinciphe zisuka esimweni sokumbozwa ziye ekuxineni okucishe kugcwale. Leyo nqubo - ukuqina - yiyona ndlela kuphela i-zirconia ethola ngayo amandla ayo okugcina, ukukhanya, kanye nokunemba kobukhulu. Yeqa, futhi lokho okugayile kuseyisikhala esithambile se-ceramic esingenamsebenzi wokungena emlonyeni wesiguli.

Nansi indlela umsebenzi ohamba ngayo ngempela: uchwepheshe ugaya isimo sokubuyiselwa kwe-zirconia block (“eluhlaza” noma “emhlophe”), ethambile futhi kulula ukuyisika kulesi sigaba. Umklamo ukhuliswa ngamabomu ngo-20–25% ukuze kubhekwe ukuncishiswa ngesikhathi sokudubula. Ingcezu egayiwe bese ingena esithandweni sokushisa, lapho ilandela khona ijika elinconywa ngumenzi lokushisa, ukubamba, kanye nokupholisa, linciphe liye ezilinganisweni zalo zokugcina ngenkathi lincipha ngesikhathi esifanayo. Isinyathelo ngasinye kulolo chungechunge sixhunyiwe - ngisho nokuphambuka okuncane kujika elinciphile kuvela kamuva njengenkinga yokulingana emlonyeni wesiguli.

Iphuzu elivame kakhulu lokuhluleka akukhona ukuthi izinga lokushisa eliphakeme alinele — ukufana kwezinga lokushisa elibi ngaphakathi kwegumbi, okubonakala njengokungahambisani komthunzi ngaphakathi kweqoqo elifanayo, noma ukucindezeleka kwangaphakathi kanye nokugoba ezinhlakeni ezinkulu zamabhuloho ezishisa ngokungalingani. Lena yinkinga i -Dentex Q7 eyakhelwe ukuyixazulula, isebenzisa ubuchwepheshe bayo be-ARCS (Automatic Rapid Compensation Sintering): uhlelo lokuphakamisa olungenawo amandla okudlidliza olulungisa ngokuzenzakalelayo ibanga phakathi kwento yokusebenza nodonga lwegumbi, okukunikeza ukulawula okuqinile amazinga okushisa, ukubamba, kanye nokupholisa ukuze ukwazi ukunciphisa isikhathi somjikelezo ngaphandle kokunciphisa ubuningi noma ukukhanya.

Lona umshini osebenzayo wanoma yini eyakhelwe phezu kwesisekelo se-zirconia: imiqhele eyodwa kanye nemiqhele egcwele, lapho ukuqina komthunzi we-batch-to-batch kubaluleke kakhulu; uhlaka lwebhuloho olunamayunithi amaningi, lapho ukujiya kodonga okungalingani kudinga khona ukufana kwezinga lokushisa eliqinile ukuze kugwenywe ukugoba; kanye nokulungiswa okusekelwa yi-implant kanye nama-abutment enziwe ngokwezifiso, lapho ngisho nokushintsha okuncane kwesilinganiso sokuncipha kungaphazamisa ukulingana okunembile ngokumelene ne-implant.

Iyini I-Dental Porcelain Furnace Esetshenziselwa?

Isithando somlilo esishisayo singenza i-zirconia ibe nzima, kodwa asikwazi ukunikeza ukubuyiselwa umthunzi kanye nokugqama kwezinyo lemvelo - leyo yindawo yesithando somlilo se-porcelain. Umsebenzi waso oyinhloko uhlanganisa izinyathelo ezintathu: ukufaka i-porcelain, lapho uchwepheshe ehlanganisa khona i-ceramic ewuphuphu ngezingqimba ezilandelanayo phezu kwe-zirconia noma i-substrate yensimbi bese eshisa ngayinye; ukufaka idayi, lapho kufakwa khona idayi eliwuketshezi ukuze kulungiswe kahle umthunzi wendawo; kanye nokugqwala, lapho ukudubula kokugcina kukhiqiza ubuso obubushelelezi, obukhanyayo obulingisa i-enamel yemvelo. Izithando zomlilo ze-porcelain nazo zisingatha ububanzi bezinto zokwakha kunezithando zomlilo ezishisayo - i-porcelain ye-feldspathic, ungqimba lwe-porcelain ekubuyiselweni kwe-PFM (i-porcelain-fused-to-metal), kanye nokufaka idayi kanye nokugqwala kwe-lithium disilicate nezinye izinto ze-glass-ceramics. Empeleni, noma yini edinga ukuqeda ubuhle idlula esithandweni somlilo se-porcelain ngesinye isikhathi.

Umehluko omkhulu wehadiwe phakathi kwesithando somlilo se-porcelain nesithando somlilo esishisayo uhlelo lwe-vacuum. Ngaphandle kokukhipha umoya ekamelweni ngesikhathi sokudubula, i-porcelain powder ibamba amabhamuza omoya amancane, futhi lawo mabhamuza asakaza ukukhanya - yingakho ukulungiswa okungagcwele i-vacuum kubukeka kufana namafu noma kufana ne-chalk esikhundleni sokukhanya okukhanyayo. Bobabili odokotela bamazinyo neziguli bangabona lokho kubukeka "okufile" ngeso lenyama, yingakho ukudubula nge-vacuum kungeyona into yokuthuthukisa ongakhetha kuyo esithandweni somlilo se-porcelain - kuyizinto ezithinta itafula. Ngale kwe-vacuum, ukufana kwezinga lokushisa kanye nokunemba kohlelo kubalulekile ngokufanayo: amazinga ambalwa okushintshashintsha ekamelweni anele ukukhiqiza ukungafani kombala okubonakalayo ngaphakathi kweqoqo elifanayo, futhi ijika lokushisa/lokupholisa elingacacile lishiya isakhiwo sangaphakathi sekristalu se-porcelain singalingani, esibonakala njengokukhanya okuthe tyaba kanye nokuqedwa kobuso obufiphele.
