Ezweni lokukhiqiza izimboni, izakhi ezingabonakali zivame ukuthwala isisindo esikhulu. Njengomnikazi wefekthri yegesi enemigqa yokukhiqiza eyisikhombisa e-China, mina, Allen, ngibhekana nalezi zinto ezingabonakali nsuku zonke. Ngiyazi lokho kubaholi bebhizinisi abafana nawe, Mark, abathola usizo amagesi wezimboni akukhona nje ukugcwalisa ithangi; imayelana nokufukula ibhizinisi. Noma ngabe uhlinzeka ngomtholampilo wezokwelapha noma ilebhu yocwaningo lobuchwepheshe obuphezulu, ikhwalithi ye igesi inquma ikhwalithi yomphumela wokugcina.

Lesi sihloko kufanele sifundwe ngoba singena sijule emhlabeni ongabonakali we Ubumsulwa begesi. Sizohlola ukuthi kungani ubumsulwa bubalulekile, Kanjani igesi ehlanzekile kukhiqizwa, futhi, okubaluleke kakhulu, indlela yokugcina leyo mfanelo kulo lonke uchungechunge lokuhlinzeka. Sizobheka nitrogen, ihhashi lemboni, futhi nixoxe imikhuba emihle kakhulu ukuze uqinisekise ukuthi okuthengayo yilokho kanye okutholayo. Ukusuka I-nitrogen generator kuze kube sekugcineni uhlelo lokulethwa, sizofaka izinyathelo ezibalulekile zokuvikela utshalomali lwakho nesithunzi sakho.

Kungani Ukuhlanzeka Kwegesi Kubaluleke Kangaka Embonini Yesimanje?

Cabanga ngothuli olucekela phansi umdwebo. Manje, cabanga ngezinhlayiyana ezincane kakhulu ezicekela phansi ukukhiqizwa kwesigidi samadola. Lokhu kuyiqiniso emikhakheni eminingi namuhla. Ubumsulwa bubalulekile ngoba imishini yesimanje kanye nezinqubo zizwela ngendlela emangalisayo. A -ngcolisayo phakathi ku umfudlana wegesi kungabangela ukusabela kwamakhemikhali ukuba kuhluleke, ama-lasers ukuthi asike kabi, noma ukudla konakale ngokushesha.

Ngokuhlangenwe nakho kwami ​​​​ngithumela e-USA naseYurophu, ngibona ukuthi amakhasimende avame ukugxila emananini. Nokho, izindleko "ezimbi igesi" ihlale iphakeme kunentengo ye igesi ehlanzekile. Uma a igesi iqukethe umswakama noma umoya-mpilo lapho kungafanele khona, ingagqwalisa imishini. Lokhu kuholela ekunciphiseni isikhathi. Kumnikazi webhizinisi onqumayo njengoMark, isikhathi sokuphumula siyisitha. Ibulala ukusebenza kahle futhi idla inzuzo.

Ngaphezu kwalokho, ukuphepha akuxoxiswana ngakho. Ezicelweni zokwelapha, i ukungcola akukhona nje ukucasuka; kuyingozi empilweni. Embonini yamakhemikhali, okungalungile ukwakheka kwegesi kungakha i-pressure buildups eyingozi. Ngakho-ke, ukuqinisekisa Ubumsulwa begesi akuyona nje imfuneko yobuchwepheshe; kuyiphrothokholi yokuphepha eyisisekelo. Ivikela abasebenzi bakho, izimpahla zakho, namakhasimende akho.

Yini Ngokuqondile Echaza "Ukuhlanzeka Okuphezulu" Embonini Yegesi?

Sivame ukuphonsa igama elithi "pure," kodwa ku- imboni yegesi, ubumsulwa ngumdlalo wezinombolo. Siyilinganisa ngama-"nines." Ngokwesibonelo, standard i-nitrogen yezimboni ingase ibe msulwa ngo-99.9%. Lokhu kuzwakala kuphakeme, kodwa kusho ukuthi u-0.1% wegesi ungokunye—imvamisa umoya-mpilo noma umswakama. Lokhu kulungele amathayi aphefumulayo, kodwa hhayi kuma-electronics abucayi.

Igesi ehlanzekile ngokuvamile iqala ku-99.999% (iziyisishiyagalolunye ezinhlanu). Ukuhlanzeka okuphezulu kakhulu (I-UHP) iya phezulu kakhulu, iye ku-99.9999% (iziyisishiyagalolunye eziyisishiyagalolunye). Kuleli zinga, siyayeka ukukhuluma ngamaphesenti bese siqala ukukhuluma ngezingxenye ngesigidi (ppm) noma izingxenye ngebhiliyoni (ppb). A igesi ehlanzekile ingase ibe nomswakama ongaphansi kwe-1 ppm.

Ukubeka lokhu ngombono:

Ukuqonda lezi amazinga okuhlanzeka kubalulekile. Awufuni ukukhokhela i-UHP igesi uma ungayidingi, kodwa usebenzisa ibanga lezimboni lapho uludinga Ubumsulwa obuphezulu iyiresiphi yenhlekelele.

Ijeneretha Yenitrojeni Iqinisekisa Kanjani Ukuhlanzeka Okungaguquki?

Amafekthri amaningi ayasuka kumasilinda futhi afake awawo I-nitrogen generator. Lo mshini uyathatha umoya ozungezile futhi uyiguqule ibe ngu-a igesi elihlanzekile. Kodwa iqinisekisa kanjani ubumsulwa be-nitrogen? Isebenzisa ubuchwepheshe obufana ne-Pressure Swing Adsorption (PSA).

Phakathi kwa- Amasistimu we-PSA, umoya ocindezelwe iphushwa ngombhede wezisefo ze-carbon molecular. Lezi zisefo zihlakaniphile; babambe amangqamuzana omoya-mpilo kodwa bawayeke nitrogen dlula. Kuya nquma ubumsulwa be-nitrogen, ulungisa ukugeleza. Ukuhamba komoya okunensayo kuvumela isisefo ukuthi sibambe umoya-mpilo owengeziwe, okuholela ekuhlanzekeni okuphezulu. Ukugeleza komoya okusheshayo kukunikeza okwengeziwe igesi, kodwa ngobumsulwa obuphansi kancane.

A yesimanje I-nitrogen generator iza nabahlaziyi bakhelwe ngaphakathi. Lezi izinhlelo zokuqapha hlola njalo umoya-mpilo kanye ne-nitrogen amazinga. Uma ukuhlanzeka kwehla ngaphansi komkhawulo obekiwe, umshini umisa ngokuzenzakalelayo ukugeleza noma ukhala i-alamu. Lokhu kukunika ukuhlanzeka okungaguquki usuku nosuku. Ngoba Izicelo zezimboni -phi nitrogen isetshenziswa njenge- intshiseko igesi ukuvimbela imililo noma ukuqhuma, lokhu kwethembeka kuyinzuzo enkulu ngaphezu kokulethwa Ukunikezwa kwegesi, ezingahluka kuye ngenqwaba.

Yiziphi Izingozi Ezifihliwe Ochungechungeni Lokuhlinzeka Ngegesi?

Noma ngabe i igesi ishiya imboni yami ekuhlanzekeni okungu-99.999%, inohambo olude ngaphambi kokuthi ifinyelele ikhasimende lakho e-USA. I ukuhlinzekwa kothile yilapho iningi ukonakalisa kwenzeka. Umlandu omkhulu? I isilinda uqobo. Uma isilinda singahlanzwanga kahle noma sikhishwe ngaphambi kokuthi sigcwaliswe kabusha, esidala igesi noma umoya ongaphakathi uhlangana nokusha igesi ehlanzekile.

Enye ingozi yizindawo zokuxhuma. Ngaso sonke isikhathi uma uxhuma noma unqamula ipayipi, inani elincane lomoya lingangena. Umswakama yiwona ophikelela kakhulu. -ngcolisayo. Inamathela ezindongeni zamapayipi namapayipi. Uma umphakeli esebenzisa amapayipi ashibhile angalinganiselwe Ubumsulwa obuphezulu, umswakama ovela emoyeni empeleni ungangena odongeni lwepayipi futhi ungcolise okomile umfudlana wegesi.

Esiphathini esinjengoMark, leli yiphuzu elibuhlungu. Uthenga umkhiqizo wephrimiyamu, kodwa izinto ezisetshenziswayo ezingezinhle ziyehlisa. Kungakho ukugcina ukuhlanzeka kwegesi idinga amaphrothokholi aqinile kulo lonke uchungechunge lokuhlinzeka. Kuhilela ukusebenzisa ama-valve okuhlola ukuvimbela ukugeleza emuva nokuqinisekisa ukuthi iloli ngalinye nephampu yokudlulisa kunikezelwe kusevisi ethile ukuze kugwenywe ukungcoliswa okunqamulayo.

Kungani I-Purity Ibalulekile Ekwenziweni Kwe-Semiconductor?

Uma kukhona imboni eyodwa egcinayo igesi abahlinzeki baphaphame ebusuku, kunjalo Ukukhiqiza i-semiconductor. Ukwenza ama-microchips kuntekenteke ngendlela emangalisayo. Izici ku-chip zincane izikhathi eziyizinkulungwane kunezinwele zomuntu. I-particle eyodwa encane noma ukungcola ku inqubo igesi ingakwazi ukujikeleza i-chip, yonakalise ngokushesha.

Kulo mkhakha, amagesi ahlanzekile abalulekile. Sikhuluma ngayo Ubumsulwa be-Ultra-High amazinga lapho ukungcola kukalwa ngezingxenye ngethriliyoni ngayinye. Nitrogen isetshenziswa lapha ukuhlanza imishini nokudala indawo ehlanzekile. Uma i nitrogen inomoya-mpilo ngisho nomkhondo, insimbi ku-chip ingakhipha oxidize (ukugqwala) khona manjalo.

Kusetshenziswa amagesi ahlanzekile ukuqinisa ama-circuits nokuhlanza amagumbi. I izidingo zegesi lapha shayela emisha kulo lonke imboni yegesi. Ukuze unikeze le makethe, umphakeli kufanele ngabe usethuthukile uhlelo lokuhlanza amakhono kanye nokupakishwa kwegumbi elihlanzekile. Imele isiqongo se izindinganiso zokuhlanzeka kwegesi. Ngisho noma ungathengisi abenzi bama-chip, ukuqonda izindinganiso zabo kukusiza ukuthi uqonde ukuthi "ukuhlanza" kusho ukuthini ngempela.

I-Liquid Nitrogen vs. Amasilinda Egesi: Iyiphi Egcina Ukuhlanzeka Kungcono?

Lapho udinga ubumsulwa obuphezulu be-nitrogen, unezinketho ezimbili eziyinhloko zokulethwa: I-liquid nitrogen noma amasilinda egesi anomfutho ophezulu. Kokubili kunobuhle nokubi mayelana nobumsulwa. I-liquid nitrogen kukhiqizwa umoya opholile kuze kube yilapho uphenduka uketshezi. Le nqubo ngokwemvelo ihlukanisa ukungcola okuningi ngoba iqhwa emazingeni okushisa ahlukene. Ngakho, uketshezi ngokwalo ngokuvamile lumsulwa ngokwedlulele.

Kodwa-ke, ingozi ngoketshezi isekushiseni. Ukuze uyisebenzise, ​​kufanele uyibuyisele igesi. Uma i-vaporizer noma ipayipi ingcolile, i- igesi elihlanzekile uyangcoliswa. Amasilinda, ngakolunye uhlangothi, isitolo igesi esesivele senziwe umhwamuko futhi sahlanzwa. Ingozi lapha yile isilinda ukulungiselela.

Ngomthamo ophezulu kakhulu, uketshezi lungcono. Kodwa ngoba Ubumsulwa obuphezulu idinga ngamavolumu amancane, aphathwe ngokukhethekile amasilinda (ngokuvamile ezenziwe nge-aluminium noma ngensimbi ekhethekile) zinhle kakhulu. Zilungiswa kusetshenziswa inqubo "yokubhaka" lapho isilinda iyashiswa futhi ifakwe vacuum ukuze isuse wonke umkhondo womswakama nokunye ama-molecule egesi. Njengomphakeli we Igesi yezimboni, ngiqinisekisa ukuthi amasilinda ethu ayahlanzwa kanzima gcina ubumsulwa amakhasimende ethu ayakhokhela.

Ungawaqapha Kanjani Amazinga Obumsulwa Ngesikhathi Sangempela?

Ukwethemba kuhle, kodwa ukuqinisekiswa kungcono. Awukwazi ukubona noma ukuhogela uma nitrogen kungu-99.9% noma u-99.999%. Udinga ubuchwepheshe. Izinga legolide lokuhlaziya lithi igesi i-chromatography (GC). Umshini we-GC uthatha isampula ye igesi futhi iyihlukanise ibe izingxenye zayo ngazinye. Ikunikeza umbiko onemininingwane walokho kanye okuku- umfudlana wegesi, kuhlanganise nanoma yikuphi ukungcola.

Ingomane endaweni isizukulwane, sisebenzisa okuqhubekayo izinhlelo zokuqapha. Lezi izinzwa ezifakwe ngqo epayipini. Banikeza idatha yesikhathi sangempela ngamaleveli komoyampilo kanye nomswakama. Uma i ukuhlanzeka kwegesi ama-drifts, isistimu yazisa opharetha.

Kumthengi, ukucela Isitifiketi Sokuhlaziya (COA) yi- umkhuba omuhle kakhulu. I-COA idokhumenti evela kulebhu efakazela ukuthi isimo segesi yalelo qoqo elithile. Ungalokothi wamukele ukuthunyelwa ngaphandle kwayo. Kuwubufakazi bakho ukuthi ukuhlanzeka kwegesi kuqinisekisa ukuhambisana nezidingo zakho. Lesi sinyathelo esilula siyasiza qinisekisa ukuthobela futhi ivimbela izimangalo zomgunyathi mayelana amazinga wokuhlanza.

Iyiphi Indima Edlalwa Uhlelo Lokulethwa Ekugcineni Ukuhlanzeka Kwegesi?

Ungathola okumsulwa igesi emhlabeni, kodwa uma uyiphusha ngepayipi elingcolile, iyonakala. I Ukulethwa kwegesi uhlelo—izilawuli, amavalvu, namashubhu—ikhilomitha lokugcina lohambo. Ngoba igesi ehlanzekile, ishubhu evamile yethusi noma yerabha ngokuvamile ayilungile ngokwanele. Angakhipha umoya (akhulule amakhemikhali avaleleke) noma avumele umswakama ukuthi usakazeke kuwo.

Izinga le Ubumsulwa obuphezulu iyishubhu yensimbi engagqwali. Ingaphakathi le-tubing kufanele lifakwe i-electropolished. Lokhu kusho ukuthi yenziwe bushelelezi ezingeni le-microscopic ukuze kungabikho izindawo ezimaholoholo ukungcola ukucasha. Futhi, uhlobo lomlawuli lubalulekile. Udinga isilawuli esine-diaphragm yensimbi engagqwali. Ama-diaphragm enjoloba angamunca futhi akhulule ukungcola.

Imikhuba emihle kakhulu zihlanganisa ukuhlanza uhlelo lokulethwa. Ngaphambi kokuthi uqale ukugeleza okuyinhloko kwe igesi, usula imigqa nge igesi elihlanzekile ukukhipha noma yimuphi umoya noma umswakama ongenile ngenkathi ushintsha isilinda. Lokhu "kuhlanzwa" kubalulekile. Idela inani elincane legesi ukuvikela ubumsulwa bamagesi ngenqubo yangempela.
