Ukuhlanzwa kwe-laser yezimboni kuyinqubo yokudubula i-laser beam endaweni eqinile ukuze kukhishwe into engadingeki. Njengoba intengo yomthombo we-fiber laser yehle kakhulu eminyakeni embalwa ye-laser, abahlanzi be-laser bahlangabezana nezidingo zemakethe ezibanzi ngokwengeziwe kanye namathemba asetshenziswayo, njengokuhlanza izinqubo zokubumba umjovo, ukususa amafilimu amancanyana noma izindawo ezinjengamafutha, namafutha, kanye nokunye okuningi. Kulesi sihloko, sizohlanganisa izihloko ezilandelayo:

Kuyini ukuhlanza nge-laser?
Ngokwesiko, ukususa ukugqwala, upende, i-oxide, nokunye ukungcola endaweni yensimbi, ukuhlanza ngomshini, ukuhlanza amakhemikhali, noma ukuhlanzwa nge-ultrasonic kungase kusebenze. Ukusetshenziswa kwalezi zindlela kulinganiselwe kakhulu ngokwendawo kanye nezidingo zokunemba okuphezulu.
Ngawo-80s, ososayensi bathola ukuthi lapho kukhanyisa indawo egqwalile yensimbi ngamandla e-laser agxile kakhulu, into efakwe imisebe ibhekana nochungechunge lokusabela okuyinkimbinkimbi ngokomzimba namakhemikhali njengokudlidliza, ukuncibilika, ukuncibilika phansi, kanye nokusha. Ngenxa yalokho, ukungcola kuyasuswa ebusweni bezinto ezibonakalayo. Le ndlela elula kodwa ephumelelayo yokuhlanza ukuhlanza nge-laser, okuye kwashintsha kancane kancane izindlela zokuhlanza ezivamile emikhakheni eminingi ngezinzuzo zayo eziningi, okubonisa amathemba abanzi ekusasa.
Zisebenza kanjani izihlanzi ze-laser?
Izihlanzi ze-laser zenziwe izingxenye ezine: iumthombo we-laser we-fiber (i-laser eqhubekayo noma i-pulse), ibhodi lokulawula, isibhamu se-laser esiphathwayo, kanye nezinga lokushisa eliqhubekayo lokupholisa amanzi. Ibhodi lokulawula ukuhlanza nge-laser lisebenza njengobuchopho bomshini wonke futhi linikeza i-oda ku-fiber laser generator kanye nesibhamu se-laser esiphathwayo.
I-fiber laser generator ikhiqiza ukukhanya kwe-laser okugxilwe kakhulu okudlula ku-conduction medium Fiber kuya kusibhamu se-laser esiphathwayo. I-galvanometer yokuskena, okungaba i-uniaxial noma i-biaxial, ehlanganiswe ngaphakathi kwesibhamu se-laser ibonisa amandla okukhanya kungqimba yokungcola yomsebenzi. Ngenhlanganisela yokusabela komzimba namakhemikhali, ukugqwala, upende, ukungcola okunamafutha, ungqimba olunamathelayo, nokunye ukungcola kususwa kalula.
Ake singene emininingwaneni eyengeziwe mayelana nale nqubo. Ukusabela okuyinkimbinkimbi okuhilelekile ekusetshenzisweni kwei-laser pulse vibration, ukwanda okushisayoizinhlayiya ze-irradiated,ukubola kwe-molecular photodecompositionushintsho lwesigaba, nomaisenzo sabo esihlangeneukunqoba amandla okubopha phakathi kokungcola kanye nobuso be-workpiece. Izinto ezihlosiwe (ungqimba olungaphezulu oluzosuswa) lushiswa ngokushesha ngokumunca amandla e-laser beam futhi luhlangabezana nezidingo ze-sublimation ukuze ukungcola okuvela ebusweni kunyamalale ukuze kufinyelele umphumela wokuhlanza. Ngenxa yalokho, indawo engaphansi imunca amandla angu-ZERO, noma amandla amancane kakhulu, ukukhanya kwe-fiber laser ngeke kulimaze sanhlobo.

Ukusabela Ezintathu Laser Cleaning
1. I-Sublimation
Ukwakheka kwamakhemikhali kwesisekelo sezinto kanye nokungcola kuhlukile, kanjalo nesilinganiso sokumuncwa kwe-laser. I-base substrate ibonisa ngaphezu kuka-95% wokukhanya kwe-laser ngaphandle kwanoma yimuphi umonakalo, kuyilapho ukungcola kudonsa iningi lamandla e-laser futhi kufinyelele izinga lokushisa le-sublimation.
2. Ukunwetshwa kwe-Thermal
Izinhlayiya ezingcolisayo zimunca amandla ashisayo futhi zande ngokushesha zize ziqhume. Umthelela wokuqhuma unqoba amandla okunamathela (amandla okukhanga phakathi kwezinto ezihlukene), futhi ngaleyo ndlela izinhlayiya ezingcolile zikhishwe ebusweni bensimbi. Ngenxa yokuthi isikhathi se-laser irradiation sifushane kakhulu, singakwazi ukukhiqiza ngokushesha ukusheshisa okukhulu kwamandla omthelela oqhumayo, okwanele ukunikeza ukusheshisa okwanele kwezinhlayiya ezinhle ukuhamba kusukela ekunamatheleni kwezinto eziyisisekelo.
3. I-Laser Pulse Vibration
Ububanzi be-pulse ye-laser beam buncane kakhulu, ngakho-ke isenzo esiphindaphindiwe se-pulse sizodala ukudlidliza kwe-ultrasonic ukuhlanza ucezu lokusebenza, futhi i-wave shock izohlakaza izinhlayiya ezingcolile.
Izinzuzo ze-Fiber Laser Cleaning Machine
Ngenxa yokuthi ukuhlanza nge-laser akudingi noma yiziphi izincibilikisi zamakhemikhali noma ezinye izinto ezidlekayo, kuhambisana nemvelo, kuphephile ukusebenza, futhi kunezinzuzo eziningi:
✔I-Solider powder ngokuyinhloko imfucuza ngemva kokuhlanza, umthamo omncane, futhi kulula ukuyiqoqa nokuyisebenzisa kabusha
✔Intuthu nomlotha okukhiqizwe i-fiber laser kulula ukuyikhipha ngesikhipha intuthu, futhi akunzima empilweni yomuntu.
✔Ukuhlanzwa okungekona othintana naye, akukho midiya eyinsalela, akukho ukungcoliswa kwesibili
✔Ukuhlanza okuhlosiwe kuphela (ukugqwala, uwoyela, upende, ukunamathela), ngeke kulimaze indawo engaphansi
✔Ugesi yiwona kuphela osetshenziswayo, izindleko eziphansi zokusebenza, nezindleko zokuwulungisa
✔Ifanele izindawo okunzima ukufinyelela kuzo kanye nesakhiwo se-artifact eyinkimbinkimbi
✔Irobhothi yokuhlanza i-laser ngokuzenzakalelayo inketho, ithatha indawo yokwenziwa
Ukukhipha ukungcola njengokugqwala, isikhunta, upende, amalebula ephepha, ama-polymer, ipulasitiki, nanoma iyiphi enye into engaphezulu, izindlela zendabuko - ukuqhunyiswa kwemidiya kanye nokufakwa kwamakhemikhali - kudinga ukuphathwa okukhethekile nokulahlwa kwemidiya futhi kungaba yingozi emangalisayo endaweni kanye nakubasebenzisi. ngezinye izikhathi. Ithebula elingezansi libala umehluko phakathi kokuhlanza nge-laser nezinye izindlela zokuhlanza izimboni
