Kodi kuyeretsa laser kumagwira ntchito bwanji pazandege?

Ukadaulo woyeretsa laseramagwiritsidwa ntchito kwambiri pochiza thupi la ndege pamakampani azamlengalenga.Pokonza ndi kukonza ndege, m'pofunika kuchotsa utoto wakale pamwamba kuti upopera mafuta atsopano sandblasting kapena zitsulo burashi mchenga ndi njira zina zachikhalidwe.kuyeretsa pamwambafilimu ya penti.

Mdziko lapansi,makina oyeretsera laserakhala akugwiritsidwa ntchito pamakampani oyendetsa ndege.Pamwamba pa ndegeyo pamafunika kupentanso pakapita nthawi, koma utoto wakale wakale uyenera kuchotsedwa kwathunthu musanapente.Njira yochotsera utoto wamakina ndiyosavuta kuwononga chitsulo pamwamba pa ndege, zomwe zimabweretsa zoopsa zobisika pakuthawa kotetezeka.Pogwiritsa ntchito njira zingapo zoyeretsera laser, utoto ukhoza kuchotsedwa kwathunthu ku A320 Airbus mkati mwa masiku awiri osawononga chitsulo.

Mfundo yakuthupi yakuyeretsa laser pakuyeretsa pamwamba pa ndege:

1. Mtsinje wotulutsidwa ndi laser umatengedwa ndi wosanjikiza woipitsidwa pamwamba kuti uchiritsidwe.
2. Kuyamwa kwa mphamvu zazikulu kumapanga plasma yomwe ikukula mofulumira (gasi wosasunthika kwambiri wa ionized), yomwe imatulutsa chiwopsezo.
3. Kugwedezeka kwamphamvu kumaphwanya zowonongeka kukhala zidutswa ndikukanidwa.
4. Kuthamanga kwa mphamvu ya kuwala kuyenera kukhala kwakufupi mokwanira kuti kupewe kutentha komwe kungawononge malo omwe akuchiritsidwa.
5. Mayesero amasonyeza kuti pamene pali oxide pamwamba pazitsulo, plasma imapangidwa pazitsulo.

Kuyesa kwa laser depainting (kuyeretsa laser) pazikopa za ndege kunachitika pa laser fluences ya 2-6 J/cmexp.Pambuyo pakuyesa kusanthula kwa SEM ndi EDS, njira zoyenera zochotsera utoto wa laser ndi 5 J/cmex.Chitetezo pakuthawa kwa ndege ndi chofunikira kwambiri, ndipo palibe kutaya mwangozi komwe kumaloledwa.Chifukwa chake, ngati ukadaulo wochotsa utoto wa laser uyenera kugwiritsidwa ntchito kwambiri pakukonza ndege, kuyeretsa kosawononga ndege kuyenera kuchitika.

Pansi pamikhalidwe yosiyanasiyana yamphamvu ya laser, kukangana ndi kuvala kwa ma bowo a rivet pakhungu la ndege mutatsukidwa kudaphunziridwa ndi njira yoyeretsera laser, ndipo mikangano ndi kuvala kwa ziwalo zina pakhungu zidawunikidwa.Kuyerekeza kunapangidwa ndi zitsanzo pambuyo popera makina ndi kuyeretsa laser.Zotsatira zake zidawonetsa kuti kuyeretsa kwa laser sikunachepetse mikangano ndi kuvala kwa chinthu chilichonse pamwamba pa khungu la ndege.

Kupsinjika kotsalira, kulimba kwapang'onopang'ono komanso kutukula kwa khungu la ndege pambuyo poyeretsa laser kudawunikidwa.Poyerekeza ndi mawotchi akupera ndi kuyeretsa laser, zotsatira zake zikuwonetsa kuti kuyeretsa kwa laser sikuchepetsa kulimba kwapang'onopang'ono komanso kukana dzimbiri pakhungu la ndege.Komabe, pambuyo poyeretsa laser, pamwamba pa khungu la ndege lidzatulutsa pulasitiki, lomwe ndi vuto lomwe limafunikira chisamaliro chapadera mukamagwiritsa ntchito ukadaulo wa laser kuyeretsa khungu la ndege.

Panthawi yokonza ndege.Utoto wopaka pamwamba pa ndege uyenera kuchotsedwa, ndipo khungu la ndege liyenera kuyang'aniridwa kuti liwone ngati zawonongeka komanso ming'alu ya kutopa kuti zisachitike ngozi zapaulendo.Choncho, pochotsa mosamala utoto pamwamba pa khungu la ndege, m'pofunika kumvetsera mwapadera kuti njira yochotsera utoto iyenera kuonetsetsa kuti gawo lapansi silinawonongeke.

Njira zachikhalidwe zochotsera utoto zimaphatikizapo kuyeretsa makina, kuyeretsa akupanga, ndi kuyeretsa mankhwala.Ngakhale matekinoloje oyeretsera omwe ali pamwambawa ndi okhwima okhwima, pali zofooka zambiri.Mwachitsanzo, njira yoyeretsera makina akupera ndi yosavuta kwambiri kuwononga zinthu zapansi, njira yoyeretsera mankhwala idzawononga chilengedwe, ndipo njira yoyeretsera akupanga imachepetsedwa ndi kukula kwa workpiece, ndipo sikophweka. kuyeretsa zigawo zazikuluzikulu.

M'zaka zaposachedwa, ndi chitukuko chofulumira chaukadaulo wa laser, ukadaulo woyeretsa laser wasanduka ukadaulo woyeretsa womwe umakhala wodziwikiratu, womveka bwino, komanso wotsika mtengo.Ukadaulo woyeretsa wa laser wagwiritsidwa ntchito kwambiri pakuchotsa utoto ndi dzimbiri, kuyeretsa nkhungu ya matayala, chitetezo chazikhalidwe, kuyeretsa nyukiliya, ndi zina zambiri.

Ngati mukufuna kudziwa zambiri za kuyeretsa laser, kapena mukufuna kukugulirani makina abwino kwambiri oyeretsera laser, chonde siyani uthenga patsamba lathu ndikutumiza imelo mwachindunji!
