Ityhubhu yequartz eyenzelwe ubungakanani obukhulu / isekiweyo iityhubhu yequartz
Kwiindawo zokusetyenziswa kwamandla kunye ne-semiconductors, siya kusebenzisa iibhubhu ze-quartz ezinkulu (ukusuka kwi-D200mm ukuya kwi-D500mm okanye ngaphezulu). Ngexesha elifanayo, iimfuno zomgangatho weetyhubhu ze-quartz nazo zingqongqo kakhulu. Umzekelo, akukho maqamza, amachaphaza erhasi, imigca yerhasi, kunye nomphezulu ocacileyo ogudileyo. Ngokuqhelekileyo sineendlela ezimbini eziqhelekileyo zokuvelisa iityhubhu zequartz ezinkulu. Sibabiza ngokuthi "I-quartz tube eqhelekileyo" kunye "nemibhobho ye-quartz eyenziwe". Ezi ndlela zimbini zemveliso zineenzuzo zazo kunye nezingeloncedo zazo. Siya kukhetha eyona ilungileyo ngokusekelwe kwimeko yokusetyenziswa komthengi.
"Ityhubhu yequartz eqhelekileyo"
Olu hlobo lwetyhubhu yequartz iveliswa ngokunyibilika kwesanti yequartz yococeko oluphezulu kwiziko lombane, emva koko iqukuqelele ulwelo oludityanisiweyo lwesilika ngokwendalo ecaleni komlomo wokubumba ukwenza imilo yetyhubhu ngokuxhuzula. Ityhubhu yequartz eqhelekileyo isetyenziselwa ukuvelisa i-quartz encinci yedayamitha. Ngophuhliso lwetekhnoloji, ububanzi betyhubhu yequartz eqhelekileyo iya iba nkulu kwaye ibe nkulu.
Iityhubhu zequartz eziqhelekileyo zinezi nzuzo. a. Imveliso enkulu kunye nexabiso eliphantsi, b. Iindonga zemibhobho egudileyo necacileyo (imigca engabonakaliyo kwiliso lenyama), c. Akukho mda wobude.
Kodwa kukwakho nezinye iingxaki. a. Udonga lwemibhobho ezotyiweyo etyebileyo nangaphezulu ithanda ukuba neziphene ezifana namaqamza, imigca yerhasi, kunye neendawo zerhasi. Ezi ziphene azimkelekanga kwintsimi ye-semiconductor. b. Ukujikeleza kombhobho kubi. Oko kukuthi, ukunyamezela kwakhe kwe-diameter yangaphandle kukhulu. Oku kungenxa yokuba phantsi kwesenzo sobunzima, udonga lombhobho ophezulu wokushisa luya kuncipha ngenxa yempembelelo yoxinzelelo lomoya.
"Yenza ityhubhu yequartz"
Yakha ityhubhu ye-quartz, eyaziwa ngokuba yityhubhu yesibini eyenziweyo. Indlela yokuvelisa ibandakanya ukujikeleza i-lathe yesibini yokwenza kunye nokufudumeza udonga lwetyhubhu ye-quartz kunye nelangatye le-hydrogen oksijini ukuya kwimeko etyhidiweyo. Yandisa udonga lwetyhubhu yequartz ngokusebenzisa i-centrifugation. Lungisa i-diameter yetyhubhu ye-quartz ukuba iqhutywe ngokusebenzisa i-graphite trowel. Emva koko uhambise ngokulinganayo i-graphite trowel ukuze usebenze yonke ityhubhu ye-quartz kwi-diameter efunekayo. Ngexesha elifanayo le-centrifugation, ixabiso lokunciphisa libalwa ngomthamo, kwaye iiparitha zokutya zomphathi we-lathe zilungelelaniswe ukulawula ububanzi kunye nodonga lwe-quartz tube. Inzuzo enkulu yale nkqubo kukuba iyakwazi ukucubungula ityhubhu ye-quartz ibe yi-diameter enkulu ngaphandle kokuchaphazela imilo kunye nokuchaneka kobungakanani betyhubhu ye-quartz, ukwenzela ukuhlangabezana neemfuno zezicelo eziphathekayo. Iityhubhu zequartz ezenziweyo zineenzuzo kunye nokungona kwazo. Iingenelo zayo zikumgangatho ophezulu (akukho bubble gas point line gas), ubukhulu obuncinci ukunyamezela ubungakanani bobukhulu obungaphandle, kunye nokukwazi ukucubungula iityhubhu zequartz ezinkulu (OD500 ~ 1000mm). Ukungalungi kwendalo yindleko ephezulu, kwaye iindawo ezinkulu zinokuba neepateni ezincinci ze-wavy (ezingamkelekanga kwintsimi ye-optical field).
Ukushwankathela, ityhubhu yequartz eyenziweyo yimveliso yesibini yokwenziwa kwetyhubhu yequartz eqhelekileyo. Injongo yalo kukufezekisa imilinganiselo emikhulu, ukuchaneka okungcono, kunye nokuphucula umgangatho weetyhubhu ze-quartz. Ungazikhathazi kakhulu malunga nokukhetha uhlobo lwetyhubhu yequartz oza kuyisebenzisa. Yenza ukhetho olusekelwe kwimeko yokusetyenziswa. Singazisombulula iingxaki zemigca yerhasi yeqamza kunye nokujikeleza okwenyani kubungakanani obukhulu ityhubhu yequartz eqhelekileyo ngokulungiswa kokuncedisa. Ukusetyenziswa kokugqibela kweetyhubhu ze-quartz ezinobubanzi obukhulu kufana neetyhubhu zokulungisa izinto ezikrwada kwi-semiconductor kunye nemimandla yamandla.
