Ukuhlanza i-laser kusebenza kanjani endizeni?

Ubuchwepheshe bokuhlanza i-laserisetshenziswa kakhulu ekwelapheni okungaphezulu komzimba wendiza embonini ye-aerospace.Lapho ulungisa futhi unakekela indiza, kuyadingeka ngokuyisisekelo ukususa upende omdala endaweni ukuze kufafazwe i-sandblasting kawoyela entsha noma ibhulashi lensimbi kanye nezinye izindlela zendabuko.ukuhlanza ubusoifilimu kapende.

Emhlabeni,laser yokuhlanza izinhlelokudala zisetshenziswa embonini yezindiza.Ingaphezulu lendiza lidinga ukupendiwa kabusha ngemva kwesikhathi esithile, kodwa upende wangempela omdala udinga ukususwa ngokuphelele ngaphambi kokupenda.Indlela yendabuko yokususa upende oyimishini kulula ukubangela umonakalo endaweni yensimbi yendiza, okuletha izingozi ezifihliwe ekundizeni okuphephile.Ngokusebenzisa izinhlelo eziningi zokuhlanza nge-laser, upende ungasuswa ngokuphelele ku-A320 Airbus zingakapheli izinsuku ezimbili ngaphandle kokulimaza ingaphezulu lensimbi.

Isimiso esingokomzimba sokuhlanza i-laser ekuhlanzeni indawo yendiza:

1. I-beam ekhishwa yi-laser imuncwa ungqimba olungcolisayo olungaphezulu ukuze lwelashwe.
2. Ukumuncwa kwamandla amakhulu kwakha i-plasma ekhula ngokushesha (igesi engazinzile ene-ionized), ekhiqiza igagasi lokuthuka.
3. Igagasi lokwethuka lihlephula ukungcola libe yizicucu futhi liyenqatshwa.
4. Ububanzi be-pulse light kufanele bube bufushane ngokwanele ukugwema ukunqwabelana kokushisa okungalimaza indawo ephathwayo.
5. Ukuhlola kubonisa ukuthi uma kune-oxide endaweni yensimbi, i-plasma ikhiqizwa endaweni yensimbi.

Ukuhlolwa kwe-laser depainting (ukuhlanza i-laser) ezikhumbeni zendiza kwenziwe nge-laser fluences ye-2–6 J/cmexp.Ngemuva kokuhlolwa kokuhlaziywa kwe-SEM ne-EDS, amapharamitha enqubo yokususa upende we-laser ayi-5 J/cmex.Ukuphepha endizeni yendiza kubaluleke kakhulu, futhi akukho ukulahleka kwengozi okuvunyelwe.Ngakho-ke, uma ubuchwepheshe bokususa upende we-laser buzosetshenziswa kabanzi ekunakekeleni indiza, ukuhlanzwa okungabhubhisi kwendiza kufanele kufezeke.

Ngaphansi kwezimo ezihlukene zokuminyana kwamandla e-laser, ukungqubuzana nokugqokwa kwezindawo zezimbobo ze-rivet zesikhumba sendiza ngemva kokuhlanzwa kwacutshungulwa inqubo yokuhlanza i-laser, futhi izakhiwo zokungqubuzana nokugqokwa kwezinye izingxenye esikhumbeni zahlolwa.Ukuqhathanisa kwenziwa ngamasampula ngemuva kokugaya ngomshini nokuhlanza nge-laser.Imiphumela yabonisa ukuthi ukuhlanzwa nge-laser akuzange kunciphise ukungqubuzana nokugqoka kwanoma iyiphi ingxenye ebusweni besikhumba sendiza.

Ukucindezeleka okuyinsalela, ukuqina okuncane nokusebenza kokugqwala kwendawo yesikhumba sendiza ngemva kokuhlolwa kwe-laser.Uma kuqhathaniswa nokugaya ngomshini nokuhlanza nge-laser, imiphumela ibonisa ukuthi ukuhlanzwa nge-laser akunciphisi ukuqina okuncane nokugqwala kwendawo yesikhumba sendiza.Kodwa-ke, ngemva kokuhlanza nge-laser, ingaphezulu lesikhumba sendiza lizokhiqiza ukubola kwepulasitiki, okuyinkinga edinga ukunakwa okukhethekile lapho kusetshenziswa ubuchwepheshe bokuhlanza i-laser ukwelapha ubuso besikhumba sendiza.

Ngesikhathi sokulungiswa kwendiza.Upende ezindaweni zendiza kufanele ususwe, futhi indawo yesikhumba sendiza kufanele ihlolwe ukuze kubonakale ukonakala nokuqhekeka kokukhathala ukuze kugwenywe izingozi zendiza.Ngakho-ke, ohlelweni lokususa ngokucophelela upende ebusweni besikhumba sendiza, kuyadingeka ukunaka ngokukhethekile ukuthi inqubo yokususa upende kufanele iqinisekise ukuthi i-substrate ayilimazi.

Izinqubo zendabuko zokususa upende zifaka ukuhlanza ngomshini, ukuhlanzwa kwe-ultrasonic, nokuhlanza amakhemikhali.Nakuba lobu buchwepheshe bokuhlanza obungenhla bungobuchwephesha bokuhlanza obuvuthiwe, kusenezingqinamba eziningi.Isibonelo, indlela yokuhlanza yokugaya ngomshini kulula kakhulu ukubangela ukulimala kwesisekelo, indlela yokuhlanza amakhemikhali izongcolisa imvelo, futhi indlela yokuhlanza i-ultrasonic inqunyelwe ubukhulu be-workpiece, futhi akulula. ukuhlanza izingxenye ezinkulu.

Eminyakeni yamuva, ngokuthuthuka okusheshayo kobuchwepheshe be-laser, ubuchwepheshe bokuhlanza i-laser buye baba ubuchwepheshe bokuhlanza obuzenzekelayo, obucacile, futhi obushibhile.Ubuchwepheshe bokuhlanza i-laser busetshenziswe kabanzi ekususeni upende nokugqwala, ukuhlanza isikhunta samasondo, ukuvikelwa kwezinsalela zamasiko, ukuhlanzwa kwenyukliya, njll.

Uma ufuna ukufunda okwengeziwe mayelana nokuhlanza i-laser, noma ufuna ukukuthengela umshini wokuhlanza we-laser ongcono kakhulu, sicela ushiye umlayezo kuwebhusayithi yethu futhi usithumele i-imeyili ngokuqondile!
