Isingeniso: Eminyakeni yamuva nje, ngokukhuphuka okusheshayo kwezimoto ezintsha zamandla kanye nobuhlakani bokwenziwa, isidingo sama-semiconductors siye saqhubeka sikhula. Ukuthuthukiswa okusheshayo kobuchwepheshe obukhaliphile kusheshise ukuguqulwa kosayizi we-semiconductor ukusuka ezingeni le-microelectronic kuya ezingeni le-athomu. Ama-semiconductors esizukulwane sesithathu angenisa inkathi entsha yentuthuko yekhwalithi ephezulu! Ngesikhathi esifanayo, inqubo yokukhiqiza nayo iyinkimbinkimbi kakhulu. Yimiphi imikhiqizo evela kwa-Hikelok engasiza ekuthuthukisweni kwe-semiconductor? Masifunde okwengeziwe ndawonye!
Ubuchwepheshe obusafufusa obufana nobuhlakani bokwenziwa kanye nedatha enkulu kungamandla ayinhloko okuqhuba intuthuko, okuholela esidingweni sokupakisha ukusebenza okukhulu kuma-chips amancane. Lokhu kusho ukuthi inqubo yokukhiqiza izoba yinkimbinkimbi kakhulu, idinga amandla okuphendula ngokushesha kanye nokuthembeka okuphezulu kwengxenye ukuze kuqinisekiswe ukuthuthwa kwamakhemikhali okunembayo okuphezulu kuzoba yinto ehamba phambili.
Ngenxa yokunemba nobunkimbinkimbi bokwenziwa kwe-semiconductor chip, kungakhathaliseki ukuthi ama-valve okulawula igesi okunembile noma izixhumi zamapayipi zokuphatha amagesi kagesi, kufanele ahambisane namazinga omkhakha we-ASTM kanye ne-SEMI afanelekile futhi abe nezici ezilandelayo:
1. Izinto zokusetshenziswa zensimbi engagqwali kufanele zicwengisiswe kusetshenziswa i-VAR ehlanzekile kakhulu noma i-VIM-VAR ukuze kuqinisekiswe imfuneko yokuhlanzeka okuphezulu okuvela emthonjeni;
2. Indawo engaphakathi lapho ithintana nendawo idinga ukwenza izinqubo ezifana nokupholishwa kwe-electrochemical kanye ne-passivation ukuze kuzuzwe ukuhlanzeka okukhulu ngenkathi kuthuthukiswa ukumelana nokugqwala komkhiqizo;
3. Insimbi engagqwali nemikhiqizo yepulasitiki kufanele ihlangabezane namazinga afanele embonini ye-ASTM kanye ne-SEMI njengokulawulwa kokuhlaziywa komswakama wangaphakathi, ukulawulwa kokuhlaziywa kwe-organic carbon (TOC) isiyonke, kanye nokulawulwa kokwakheka kwe-ion.
Imikhiqizo yochungechunge lwe-Hikelok ye-ultra-high purityukuhlangabezana nezidingo zemboni ye-semiconductor yezingxenye zoketshezi futhi uthobelane namazinga embonini ye-ASTM kanye ne-SEMI, okuhlanganisa ukukhethwa kwempahla eluhlaza, ubuchwepheshe obusezingeni eliphezulu bokucubungula, nokuhlolwa kwenhlangano endaweni yokusebenzela engenalo uthuli ezingeni le-100. Izinhlobo zomkhiqizo zihlanganisa ama-valve okunciphisa ingcindezi yokuhlanzeka okuphakeme kakhulu, amavalvu e-diaphragm ehlanzekile, ama-valve avaliwe, amaphaneli ahlanganisiwe, okokufakwa kokuhlanzeka okuphezulu, kanye namashubhu e-EP. Izinhlobo zosayizi abaningi ziyatholakala, futhi ukwenza ngokwezifiso kungenziwa ngokuya ngezidingo zokufakwa kobunikazi esizeni.
1,Ukufakwa kokuhlanzeka okuphezulu okuphezulu &Izinsimbi ezishiselwe izinqe
Ukufakwa kokuhlanzeka okuphezulu okuphezulu
Ukwamukela insimbi efomini lokuvala lensimbi ukuze kuzuzwe ukutywinwa okuthembekile kwemikhiqizo ngaphakathi kwe-vacuum kanye nebanga lokucindezela okuhle. Ngemuva kwenqubo yokwelapha ejwayelekile, ubulukhuni obumaphakathi bokupholishwa kwendawo ehlangene yokuhlanzeka okuphezulu kakhulu lapho kuthintana nendawo ephakathi kungahlangana no-10% μ In. (0.25 μ m) Ra; Ngemuva kokwelashwa kwenqubo yokuhlanzeka okuphakeme kakhulu, ubulukhuni obumaphakathi bobuso obupholishiwe lapho buthintana nendawo bungahlangana no-5 μ In. (0.13 μ m) I-Ra. I-ultra-high pure joint nut yakhelwe ngembobo yokuthola ukuvuza, esiza ukutholwa kokuvuza. Izintambo zamantongomane ziphathwa ngenqubo yesiliva yokucwenga ukuze kuncishiswe ukugqokwa kwentambo futhi kuncishiswe ubungozi bokubandakanyeka kwentambo ngesikhathi sokufakwa.
I-Miniature Butt Welded Fittings
Ingcindezi yokuklama ibalwa ngokusekelwe ku-ASME B31.3 ne-ASME B31.1. Isakhiwo sihlangene futhi sihlangene, sinezilinganiso eziqondile. Ukuphela kwe-welding kuqondile ngaphandle kwama-burrs, futhi ubukhulu bodonga buyiyunifomu. Ingakwazi ukufeza ukuhambisana okuphezulu namapayipi e-EP futhi ithuthukise ukuzinza kwe-welding. Ubunzima bendawo yangaphakathi yelunga bungafinyelela ku-5 μ In. (0.13 μ m) Ra, ubuhwaba obujwayelekile bendawo ngemva kokwelashwa kwenqubo evamile ngu-10 μ In. (0.25 μ m) I-Ra. Amalunga aphethwe ngokukhethekile futhi ahlanziwe afaneleka kuzinhlelo zokuhlanzeka okuphezulu kakhulu, izinqubo ze-photovoltaic, njll., ezinezinhlobo ezihlukahlukene zosayizi ongakhetha kuzo.
Ingcindezi yokusebenza ingafinyelela ku-1000 psig (ibha engu-68.9) futhi ukumelana nokushisa okuphezulu ngu-482 ℃ (900 ℉). Singahlinzeka nge-316L, 316L VAR insimbi engagqwali kanye nezinto ezihlukahlukene ze-alloy. Idizayini yokuxhuma i-valve stem ingaqinisekisa ukunyakaza okuthembekile kwesiqu se-valve. Idizayini yekhanda le-valve elingaphenduki linciphisa ukuguga endaweni yesihlalo sevalvu, futhi ipayipi likathayela elakhiwe ngokunemba linikeza ukusebenza okuthembekile kokuvala nempilo yesevisi. Ukushaywa kwepayipi likathayela kulawulwa ngokuqinile, kuthuthukisa ngokuphumelelayo ukuphepha nokuphila kwenkonzo yepayipi likathayela.
Ingcindezi yokusebenza ingafinyelela ku-500 psig (ibha engu-34.4) futhi ukumelana nokushisa okuphezulu ngu-93 ℃ (200 ℉). I-316L kanye ne-316L VAR izinto zensimbi engagqwali, amakhanda amavalvu e-PCTFE azenzakalelayo ahambisana nemidiya eminingi, futhi amakhanda e-valve e-PI (polyimide) anganikezwa. Idizayini yesivalo sevalvu ehlangene ephephile futhi enokwethenjelwa, ipayipi likathayela elakhiwe ngokunemba linikeza ukusebenza okuthembekile kokuvala kanye nempilo yesevisi, okwenza ukuvala kwevalve yamapayipi kathayela kuphephe futhi kuthembeke. Isiqu se-valve yokushayela eklanywe ngokukhethekile sibushelelezi.
Ingcindezi yokusebenza ingafinyelela ku-375 psig (25.8 bar) futhi ukumelana nokushisa okuphezulu ngu-82 ℃ (180 ℉). 316L impahla yensimbi engagqwali enomklamo wokugeleza okuphezulu. Idizayini yokuxhuma isiqu se-valve iqinisekisa ukunyakaza okuthembekile kwesiqu se-valve, futhi ukwakheka kwekhanda le-valve elingaphenduki linciphisa ukuguga endaweni yesihlalo se-valve. Umklamo womzimba we-valve omise okwe-Y uqinisekisa ukuthi i-inlet ne-outlet ye-valve itholakala ku-eksisi efanayo, inikeza izinga lokugeleza okuphezulu nokunciphisa ukumelana nokugeleza. Ukwelashwa kwe-electrochemical polishing endaweni engaphakathi, ihlanzekile futhi ibushelelezi. Ifaka izinga lokugeleza okuphezulu, ukusebenza kokuvalwa okuphezulu, nokuphepha okuphezulu, kuyisinqumo esingcono kakhulu sezinqubo zokusabalalisa igesi yenqubo yokuhlanzeka okuphezulu, amasistimu okuhlanza, amasistimu okuhlunga, kanye nezinhlelo zokusabalalisa amakhemikhali ahlanzekile.
3, Ama-valve okwehlisa ingcindezi yokuhlanzeka okuphezulu kakhulu
Lena idivayisi elawula ukucindezela, esetshenziselwa kakhulu ukulawula ingcindezi yokukhuphuka nomfula kanye nesistimu, ilungise ngokuzenzakalelayo ku-inthanethi, futhi igade inani lokucindezela kwesistimu yempendulo ngesikhathi sangempela. Ingcindezi enkulu yokungenisa yomkhiqizo ingafinyelela ku-3500psig (241bar), futhi ububanzi bengcindezi yokuphumayo bukhethwa ngokuya ngesimo sangempela somsebenzi. Kukhethwa izinto zokuvala izihlalo zama-valve amaningi, ezingasetshenziswa kumagesi agqwalayo nasezimeni ezikhethekile zegesi, ezifanele izimo zokusebenza nezimo ezihlukahlukene. Ingaphakathi lomkhiqizo lipholishelwe ngama-intshi angu-10 (0.25) μ m) I-Ra, i-diaphragm kanye nomzimba we-valve kuyinsimbi evalwe ngokugcwele ngokwethembeka okuphezulu.
Ingcindezi ephezulu (3045psig/210bar) kanye nengcindezi ephansi (250psig/17.2bar) izinhlobo ezimbili ziyatholakala ukuze uzikhethe. I-316L VAR kanye ne-316L VIM-VAR impahla ye-valve iyatholakala, enezinketho eziningi zokusebenza ngesandla kanye ne-pneumatic. Idizayini yesihlalo sevalvu ye-PCTFE evalwe ngokugcwele isebenzisa impahla ye-Elgiloy diaphragm ukuze kuthuthukiswe amandla nokumelana nokugqwala, nempilo ende yesevisi kanye nokupholishwa kwe-electrochemical kwangaphakathi okungafika ku-5uin (0.13) μ m) Ra, izinga lokuvuza le-helium lingaphansi koku-1 × 10-9std cm3/s
EP amashubhu
Ukupholishwa kwe-electrochemical kwangaphakathi okunobunzima obungu-10 μ In. (0.25 μ m) Ra, indawo engaphandle ipholishwe ngomshini, iwashwa nge-asidi nezinye izinqubo, iveza isimo esikhanyayo. Izikhathi ezi-4 kusici sokuphepha ukuqinisekisa ukusetshenziswa okuphephile nokuthembekile.
Okungenhla yizinhlelo zokusebenza ezikhethwayo embonini ye-semiconductor. I-Hikelok ihambisana nokuthuthuka komkhakha we-semiconductor futhi isebenzisa isipiliyoni sayo somkhiqizo ocebile ukuletha imikhiqizo esebenza kahle kakhulu nesezingeni eliphezulu embonini! Ukuze uthole imininingwane eyengeziwe yoku-oda, sicela ubheke imanuwali yokukhetha iwebhusayithi esemthethweni ye-Hikelok. Uma unanoma yimiphi imibuzo yokukhetha, sicela uxhumane nabasebenzi abathengisa ku-inthanethi be-Hikelok bamahora angu-24.
