Kungani Khetha I-Laser Cleaning?

Abakhiqizi bahlale befuna ukwenza imikhiqizo enamandla, ehlala isikhathi eside, futhi ethembeke kakhulu, kanye nasemikhakheni yezimoto kanye ne-aerospace.Kulo mbono, bavame ukuthuthukisa futhi bashintshe amasistimu wezinto ezibonakalayo ngokuminyana okuphansi, izinga lokushisa elingcono kanye nama-alloys ensimbi angagqwali.Lokhu kunikeza abakhiqizi indawo engcono emakethe.

Empeleni, lokho kuyingxenye yendaba.
Inzuzo yamasu enamandla nakakhulu isiqiniseko esingalinganiseki mayelana namandla omkhiqizo, ukuqina, nokuthembeka.
Ukushintsha izinto ezindala ukuze uthole eziqinile kungaba isiqalo esihle, kodwa futhi kudinga izinqubo zokukhiqiza ezithuthuke kakhulu ezincike ekuhlanzeni nasekuhlanzeni indawo esebenza ngempumelelo ukuze kwakhiwe izakhiwo eziqinile.Izinsimbi ezifana ne-aluminium alloys kanye nezinto ezithuthukisiwe ezifana ne-carbon fiber polymer composite, evame ukusetshenziswa ekukhiqizeni izimoto kanye ne-aerospace, zidinga ukubopha ukuze kuncishiswe isisindo - lapho kusetshenziswa izinsimbi, isisindo sengezwa esakhiweni - nokudala amalunga anokwethenjelwa.
Izindlela zendabuko zokuqeda i-aluminium zihlanganisa i-sandblasting, ukusula i-solvent, okulandelwa ukugaya (ukusebenzisa iphedi yokukhuhla) noma i-anodizing.I-Adhesive bonding ivula umnyango wezinqubo ezizenzakalelayo ezengeziwe lapho ukuqedwa kwendabuko kungahambisani.
I-anodizing ivame kakhulu ezinhlelweni ze-aerospace lapho lokhu kulungiselelwa okumba eqolo futhi okuqinile kusetshenziselwa ukuhlangabezana nezimfuneko eziqinile.Ukuhlukahluka okungokwemvelo kokuqhunyiswa kwesihlabathi namasu okuhuzuka okwenziwa ngesandla kubonisa ngokusobala ukuthi inqubo elawulwa kakhulu ilungile.
Ukuhlanzwa kwe-laser noma ukukhipha nge-laser kugcwalisa lesi sikhala senqubo njengendlela enembe kakhudlwana, enobungani bemvelo, ezenzakalelayo futhi ephumelelayo yokwelapha insimbi nezindawo eziyinhlanganisela zokuhlanza.Izinhlobo zokungcola ezitholakala ebusweni balezi zinto zisuswa kalula ngokucubungula i-laser.
Ngenxa yokuthi ukuhlanza nge-laser kunamandla kakhulu, kubalulekile ukwazi ukuthi kuthinta kanjani indawo yakho.Umehluko phakathi kwendawo ephathwe kahle nendawo enganakeke kakhulu noma enganakeke kakhulu ingaba nzima kakhulu ukuyihlola.Ngobuchwepheshe bokuqinisekisa benqubo yobuningi bubucayi futhi bunembe njengenqubo ye-laser ngokwayo, abakhiqizi bangaba nokuqiniseka ukuthi izindawo zabo zensimbi neziyinhlanganisela zilungele ngokuphelele ukubopha.

I-Fortune laser elandelayo izokunikeza isingeniso esiningiliziwe sezizathu zokukhetha ukuhlanzwa kwe-laser.

1 -Iyini i-Laser Cleaning?
Ukwelashwa nge-laser kuyindlela enembe ngokwedlulele, yokuhlanza okushisayo esebenza ngokususa (ukukhipha) izingxenyana ezincane zendawo ebonakalayo ngokusebenzisa induku ye-laser egxilile, evame ukucindezelwa.I-laser ikhipha imisebe ukuze ikhiphe ama-athomu futhi ingasetshenziselwa ukubhoboza izimbobo ezincane kakhulu, ezijulile ngokusebenzisa izinto eziqinile, ukukhiqiza amafilimu amancanyana noma ama-nanoparticles ngaphezulu.

Le nqubo yokuhlanza indawo iphumelela kakhulu ngenxa yekhono layo lokukhomba izingqimba ezincane zokungcola nezinsalela.Izindawo ze-Aluminium ziqukethe ama-oxide namafutha okuthambisa ayingozi ekuhlanganiseni okunamathelayo kanye nezinhlanganisela ngokuvamile zigcina ukukhishwa kwesikhunta esiyinsalela nokunye ukungcola kwe-silicone engakwazi ukwakha izibopho zamakhemikhali eziqinile ngezinto ezinamathelayo.
Uma i-adhesive isetshenziswa endaweni eyodwa yalezi zinsalela izozama ukunamathela ngamakhemikhali emafutheni nase-silicone phezulu kwezingqimba zamangqamuzana ezimbalwa zento.Lawa mabhondi abuthakathaka kakhulu futhi azohluleka nakanjani phakathi nokuhlolwa kokusebenza noma phakathi nokusetshenziswa komkhiqizo.Lapho amalunga ephuka endaweni lapho okungaphezulu nokunamathelayo noma okunamathelayo kuhlangana khona lokhu kubizwa ngokuthi ukwehluleka kobuso obuhlangene.Ukwehluleka okuhlangene ngesikhathi sokuhlolwa kwe-lap shear yilapho ikhefu lenzeka ngaphakathi kwe-adhesive ngokwayo.Lokhu kuyinkomba yesibopho esiqine kakhulu kanye nesakhiwo esihlanganisiwe esiqinile futhi esihlala isikhathi eside.

Ukwehluleka okuhlangene kwalawa masampuli ayinhlanganisela alashwe nge-laser kukhombisa ukunamathela kuzo zombili izinhlangothi zezinto eziboshiwe.

Ukungaphumeleli kokuhlanganisa ubuso kwalawa masampula ayinhlanganisela angazange aphathwe kukhombisa ukuthi ingcina inamathele kolunye lwezinhlangothi futhi yadedela enye ngokuphelele.
Uma unokwehluleka okubumbene, unesibopho esiphakathi kobuso esingayekeleli ngeze.Ukwelapha okungaphezulu kuhloswe ukulungisa indawo engaphezulu ukuze kukhishwe ukungcola nokudala noma kwembule indawo ezokwazi ukuxubana ngokwekhemikhali ne-adhesive kumabhondi ahlala isikhathi eside futhi athembekile.
