1, Ukwakheka kwamakhemikhali ensimbi ebusweni obuqondiwe
Ikuphi inhlanganisela eyakhiwe enkambisweni yokwakha inhlanganisela kusuka endaweni eqondiwe yensimbi ngenqubo yokuphalaza okusebenzayo? Njengoba ukusabela kwamakhemikhali phakathi kwezinhlayiya zegesi ezisebenzayo kanye nama-athomu obuso obuqondiwe kukhiqiza ama-athomu ahlanganisiwe, okuvame ukuba yi-exothermic, ukushisa kokusabela kumele kube nendlela yokuphuma, ngaphandle kwalokho ukusabela kwamakhemikhali akukwazi ukuqhubeka. Ngaphansi kwezimo ze-vacuum, ukudluliselwa kokushisa phakathi kwamagesi akunakwenzeka, ngakho-ke ukusabela kwamakhemikhali kumele kwenzeke endaweni eqinile. Ukuphalaza okusabelayo kukhiqiza ama-compound ezindaweni eziqondiwe, ezindaweni ezingaphansi komhlaba, nakwezinye izindawo ezihlelekile. Ukukhiqiza ama-compound ebusweni be-substrate kuwumgomo, ukukhiqiza ama-compound kwezinye izindawo ezihlelekile kuwukuchitha izinsiza, futhi ukukhiqiza ama-compound ebusweni obuqondiwe kuqala njengomthombo wama-athomu ahlanganisiwe futhi kuba yisithiyo ekuhlinzekeni ngokuqhubekayo ama-athomu engeziwe ahlanganisiwe.
2, Izici ezithinta ubuthi obuqondiwe
Isici esiyinhloko esithinta ubuthi obuqondiwe yisilinganiso segesi yokusabela kanye negesi eqhumayo, igesi yokusabela eningi kakhulu izoholela ebuthi obuqondiwe. Inqubo yokuqhuma okusabelayo yenziwa endaweni yesiteshi sokuqhuma okuqondiwe ibonakala imbozwe yinhlanganisela yokusabela noma inhlanganisela yokusabela ihlutshiwe futhi iphindwe ivele ebusweni bensimbi. Uma izinga lokukhiqizwa kwenhlanganisela likhulu kunezinga lokuhlubula inhlanganisela, indawo yokumboza inhlanganisela iyanda. Ngamandla athile, inani legesi yokusabela elihilelekile ekukhiqizweni kwenhlanganisela liyanda futhi izinga lokukhiqizwa kwenhlanganisela liyanda. Uma inani legesi yokusabela likhuphuka ngokweqile, indawo yokumboza inhlanganisela iyanda. Futhi uma izinga lokugeleza kwegesi yokusabela lingenakushintshwa ngesikhathi, izinga lokukhuphuka kwendawo yokumboza inhlanganisela alincishiswa, futhi isiteshi sokuqhuma sizombozwa kakhulu yinhlanganisela, lapho inhloso yokuqhuma imbozwe ngokuphelele yinhlanganisela, inhloso inobuthi ngokuphelele.
3, Isenzakalo sobuthi obuqondiwe
(1) ukuqongelela kwama-ion amahle: lapho ubuthi obuqondiwe bukhona, kuzokwakhiwa ungqimba lwefilimu yokuvikela kuzokwenzeka ebusweni bokuqondiwe, ama-ion amahle afinyelela ebusweni bokuqondiwe kwe-cathode ngenxa yokuvaleka kongqimba lokuvikela. Angangeni ngqo ebusweni bokuqondiwe kwe-cathode, kodwa aqongelela ebusweni bokuqondiwe, kulula ukukhiqiza insimu ebandayo ukuze ikhiphe i-arc — i-arcing, ukuze ukuchitheka kwe-cathode kungakwazi ukuqhubeka.
(2) ukunyamalala kwe-anode: lapho ubuthi obuqondiwe buvela, udonga lwegumbi lokuhlanza olusekelwe phansi luphinde lufake ifilimu yokuvikela, ama-electron e-anode awakwazi ukungena ku-anode, ukwakheka kwento yokunyamalala kwe-anode kwenzeka.
4, Incazelo ebonakalayo yobuthi obuqondiwe
(1) Ngokuvamile, i-coefficient yesibili yokukhishwa kwama-electron kwamakhemikhali ensimbi iphakeme kuneyensimbi. Ngemva kokufaka ubuthi ekuqondisweni, ubuso bokuqondiswe buyizakhi zensimbi kuphela, futhi ngemva kokuhlaselwa ngama-ion, inani lama-electron esibili akhishwayo liyakhula, okuthuthukisa ukuhanjiswa kwesikhala futhi kunciphisa impedance ye-plasma, okuholela ku-voltage ephansi yokuphalaza. Lokhu kunciphisa izinga lokuphalaza. Ngokuvamile i-voltage yokuphalaza yokuphalaza kwe-magnetron iphakathi kuka-400V-600V, futhi lapho kwenzeka ubuthi ekuqondisweni, i-voltage yokuphalaza incishiswa kakhulu.
(2) Izinga lokuphalaza ekuqaleni eliqondiwe lensimbi kanye neliqondiwe elihlanganisiwe lihlukile, ngokuvamile i-coefficient yokuphalaza yensimbi iphakeme kune-coefficient yokuphalaza yenhlanganisela, ngakho-ke izinga lokuphalaza liphansi ngemva kokufaka ubuthi kuhlosiwe.
(3) Ukusebenza kahle kokuphalaza kwegesi ephalaza ephendulayo ekuqaleni kuphansi ekusebenzeni kahle kokuphalaza kwegesi engasebenzi, ngakho-ke izinga lokuphalaza eliphelele liyancipha ngemva kokuba isilinganiso segesi ephendulayo sanda.
5, Izixazululo zokubulala abantu abahlosiwe
(1) Sebenzisa ugesi osebenzisa imvamisa ephakathi noma ugesi osebenzisa imvamisa yomsakazo.
(2) Sebenzisa ukulawula okuvaliwe kokungena kwegesi yokusabela.
(3) Yamukela izinhloso ezimbili
(4) Lawula ushintsho lwemodi yokumboza: Ngaphambi kokumboza, ijika lomphumela we-hysteresis wobuthi obuqondiwe liyaqoqwa ukuze ukugeleza komoya ongenayo kulawulwa ngaphambili kokukhiqiza ubuthi obuqondiwe ukuqinisekisa ukuthi inqubo ihlala ikwimodi ngaphambi kokuba izinga lokufakwa lehle kakhulu.
–Lesi sihloko sishicilelwe yiGuangdong Zhenhua Technology, umkhiqizi wemishini yokumboza nge-vacuum.
