Ukulawulwa Kwezinga lokushisa Okunembile Kwezinhlelo Ze-Laser Nezicelo Zezimboni Kusukela ngo-2002
Ulimi
Ngokucubungula ngokuphelele izakhiwo zezinto ezibonakalayo, imingcele ye-laser, namasu okucubungula, lesi sihloko sinikeza izixazululo ezisebenzayo zokuhlanza i-laser ezindaweni ezinobungozi obukhulu. Lezi zindlela zihlose ukuqinisekisa ukuhlanza okuphumelelayo kuyilapho kunciphisa amandla okulimala kwezinto ezibonakalayo-ukwenza ukuhlanzwa kwe-laser kuphephe futhi kuthembeke kakhudlwana ezinhlelweni ezibucayi neziyinkimbinkimbi.
Ukuhlanza i-laser kuvele njengobuchwepheshe obusebenza kahle kakhulu, obungathintani nokususwa kokunemba. Kodwa-ke, lapho usebenza ngezinto ezibucayi, kubalulekile ukulinganisa ukusebenza kahle kokuhlanza nokuvikela impahla. Lesi sihloko sethula indlela ehlelekile yokubhekana nezimo ezinobungozi obukhulu ngokuhlaziya izici zezinto ezibonakalayo, imingcele ye-laser, kanye nomklamo wenqubo.
Izindlela Zokulimala Nezinyathelo Zokulwa Zezinto Ezinobungozi Kakhulu Ekuhlanzeni I-Laser
1. Izinto Ezizwela Ukushisa
Indlela Yokulimala: Izinto ezincibilika kancane noma ukungaphatheki kahle kwe-thermal—njengamapulasitiki noma irabha—zijwayele ukuthamba, i-carbonization, noma ukuguqulwa ngenxa yokwanda kokushisa ngesikhathi sokuhlanza i-laser.
Izixazululo: (1) Okwezinto ezinjengamapulasitiki nenjoloba: Sebenzisa amalaser anamandla aphansi ahlanganiswe negesi engasebenzi (isb, i-nitrogen) yokupholisa. Ukuhlukaniswa kwe-pulse efanele kuvumela ukuchithwa okusebenzayo kokushisa, kuyilapho i-inert gas isiza ukuhlukanisa umoya-mpilo, inciphisa i-oxidation. (2) Ngezinto ezizimbobo ezifana nokhuni noma i-ceramic: Faka amalaser anamandla aphansi, ama-short-pulse anezikena eziningi. Isakhiwo sangaphakathi esinezimbotshana sisiza ukusabalalisa amandla e-laser ngokuzindla okuphindaphindiwe, kunciphisa ubungozi bokushisa okweqile kwendawo.
2. Izinto Ezihlanganisiwe Zezingqimba Eziningi
Indlela Yokulimala: Amazinga ahlukene okumunca amandla phakathi kwezendlalelo angabangela ukulimala okungahlosiwe ku-substrate noma kuholele ekuhlanganeni kokumboza.
Izixazululo: (1) Ngezinsimbi ezipendiwe noma izinhlanganisela ezinamekiwe: Lungisa i-engeli yesigameko ye-laser ukuze uguqule indlela yokubonisa. Lokhu kuthuthukisa ukuhlukaniswa kwesixhumi esibonakalayo kuyilapho kunciphisa ukungena kwamandla ku-substrate. (2) Kuma-substrates amboziwe (isb., isikhunta esifakwe nge-chrome): Sebenzisa amalaser e-ultraviolet (UV) anobude obuthile obuthile. Amalaser e-UV angakwazi ukukhetha ngokukhetha ukucwenga ngaphandle kokudlulisa ukushisa okukhulu, anciphise ukulimala kokusebenza okungaphansi.
3. Izinto Eziqinile Eziphakeme kanye Nezinqamuleli
Indlela Yokulimala: Izinto ezifana nengilazi noma i-silicon yekristalu eyodwa ingase ithuthukise ama-microcracks ngenxa yomehluko ekwandiseni okushisayo noma izinguquko ezingazelelwe kusakhiwo sekristalu.
Izixazululo: (1) Okwezinto ezifana nengilazi noma i-silicon ye-monocrystalline: Sebenzisa ama-laser we-ultra-short pulse (isb, ama-laser e-femtosecond). Ukumuncwa kwawo okungaqondile kuvumela ukudluliswa kwamandla ngaphambi kokudlidliza kwe-lattice, kunciphisa ingozi yama-microcracks. (2) Ngezinhlanganisela ze-carbon fibre: Sebenzisa amasu okubumba i-beam, njengamaphrofayili e-annular beam, ukuze uqinisekise ukusatshalaliswa kwamandla okufanayo futhi unciphise ukugxiliswa kwengcindezi ezindaweni zokuxhumanisa i-resin-fiber, okusiza ukuvimbela ukuqhekeka.
Ama-Industrial Chillers : Umlingani Obalulekile Ekuvikeleni Izinto Ngesikhathi Sokuhlanza I-Laser
Ama-chiller ezimboni adlala indima ebalulekile ekwehliseni ubungozi bokulimala kwempahla okubangelwa ukunqwabelana kokushisa ngesikhathi sokuhlanza nge-laser. Ukulawula kwabo okunembile kwezinga lokushisa kuqinisekisa amandla okukhipha i-laser azinzile kanye nekhwalithi ye-beam ngaphansi kwezimo ezihlukahlukene zokusebenza. Ukukhipha ukushisa okusebenzayo kuvimbela ukushisisa ngokweqile kwezinto ezizwela ukushisa, ukugwema ukuthambisa, i-carbonization, noma ukuwohloka.
Ngaphezu kokuvikela izinto ezisetshenziswayo, ama-chiller aphinde avikele imithombo ye-laser nezingxenye ze-optical, andise ubude besikhathi semishini. Ehlome ngezici zokuphepha ezakhelwe ngaphakathi, ama-chiller embonini anikeza izexwayiso zangaphambi kwesikhathi kanye nokuvikela okuzenzakalelayo uma kwenzeka kuba nokungasebenzi kahle, okunciphisa ubungozi bokungasebenzi kwemishini noma izigameko zokuphepha.
Isiphetho
Ngokucubungula ngokuphelele izakhiwo zezinto ezibonakalayo, imingcele ye-laser, namasu okucubungula, lesi sihloko sinikeza izixazululo ezisebenzayo zokuhlanza i-laser ezindaweni ezinobungozi obukhulu. Lezi zindlela zihlose ukuqinisekisa ukuhlanza okuphumelelayo kuyilapho kunciphisa amandla okulimala kwezinto ezibonakalayo-ukwenza ukuhlanzwa kwe-laser kuphephe futhi kuthembeke kakhudlwana ezinhlelweni ezibucayi neziyinkimbinkimbi.
