Daxalka u adkaysta Alumina Ceramic Hearth - Saxanka Mashiinada Kuleyl u adkaysta ee Deegaanka Warshadaha ee aadka u daran
Injineerka codsiyada warshadaha ugu baahida badan, Alumina Ceramic Hearth oo iska caabida daxalka waxay soo bandhigtaa waxqabad aan la barbar dhigi karin heerkulka sare iyo jawiga kimikalka leh. Sida badeecada dhoobada alumina-heer-sare ah, waxay u taagan tahay safka hore ee agabka dib-u-celinta, isku darka xasilloonida kulaylka aan caadiga ahayn, xoogga farsamada, iyo iska caabinta oksaydhka iyo xaalufka kiimikada. Mashiinkan saxda ah ee kuleylka u adkeysiga alumina dhoobada dhoobada waxaa si taxadar leh looga sameeyay 99% alumina saafi ah (Al₂O₃), hubinta joogteynta sare iyo cimri dhererka wareegyada hawlgalka dheer Ku habboon in loo isticmaalo birta, wax-soo-saarka dhalooyinka, farsamaynta semiconductor, iyo warshadaha dhoobada ee horumarsan, weelkan dhoobada ahi wuxuu ka dhigan yahay meesha ugu sarreysa ee injineernimada agabka loogu talagalay heerka ugu sarreeya warshadaha adduunka.
Waxa ka sooca alaabtan waa adkaysigeeda lakabyo badan: kaliya maaha inay u adkaysato soo-gaadhista joogtada ah ee heerkulka ka sarreeya 1600 ° C (2912 ° F), laakiin sidoo kale waxay ilaalisaa daacadnimada qaab dhismeedka marka loo eego baaskiil kulaylka degdega ah iyo jawiyada daxalka leh ee qani ku ah cusbada dhalaalay, acids, ama alkalis. Daxalka u adkaysta aluminia dhoobada dhoobada waxaa si gaar ah loogu talagalay in ay iska caabiso nabaad-guurka, dildilaaca, iyo nabaadguurka dusha sare-dhibcaha fashilka caadiga ah ee hababka dib-u-celinta caadiga ah. Isku xidhkeeda balaadhinta kulaylka hooseeya waxay hubisaa xasilloonida cabbirka kulaylka aadka u daran, iyadoo yaraynaysa dagaalka iyo kordhinta nolosha adeegga marka loo eego beddelka dhoobada ama birta caadiga ah. Is barbar dhig Nadiifinta Sare ee Alumina Ceramic, Ceramic Zirconia, Waxqabadku waa wanaagsan yahay.
Lagu soo saaray farsamooyin heersare ah oo sintering ah iyo makiinada saxda ah ee ay maamusho CNC, qalbi kastaa wuxuu gaaraa dulqaad heer-yar, isagoo dammaanad qaadaya ku habboonaanta nidaamyada foornada adag. Mashiinka saxda ah ee heerkan ayaa meesha ka saaraya baahida loo qabo hagaajinta goobta, yaraynta wakhtiga rakibaadda iyo kor u qaadida hufnaanta nidaamka. Dhammaystirka dusha sare ee cufan ayaa sii yareynaya ku dheggan walxaha waxayna fududeeyaan nadiifinta fudud, taas oo ka dhigaysa mid ku habboon codsiyada qolka nadiifka ah iyo hababka u baahan xakamaynta wasakhda adag.
