Njira zodziwika bwino zoyeretsera mafakitale zimaphatikizapo madzi othinana kwambiri, ma reagents amadzi, mafunde akupanga, ndi kupukuta kwamakina. Komabe, njira izi zoyeretsera zili ndi mavuto monga kuwonongeka kwa gawo lapansi, malo osagwira bwino ntchito, kuipitsa, kuyeretsa pang'ono, komanso mtengo wokwera kwambiri. Ndi kukulira kwa kuipitsidwa kwachilengedwe, akatswiri ochokera kumaiko osiyanasiyana akutukula njira zopulumutsira mphamvu, zachilengedwe komanso zamaukadaulo atsopano. Chifukwa laser kukonza ukadaulo uli ndi zabwino zambiri monga kuwonongeka kochepa kwa zinthu zapansi panthaka, kuyeretsa kwambiri, kutulutsa mpweya ndipo palibe kuipitsa, pang'onopang'ono kumayesedwa ndikuyanjidwa ndi maphunziro ndi makampani. Palibe kukayikira kuti kugwiritsa ntchito ukadaulo wa laser kuyeretsa dothi pamalo opangira zitsulo kuli ndi chiyembekezo chokwanira kwambiri.
Mbiri yakutukuka ndi mkhalidwe wapano waukadaulo wa laser
In the 1960s, the famous physicist Schawlow first proposed the concept of laser cleaning, and then applied the technology to the repair and maintenance of ancient books. Laser cleaning has a wide range of decontamination, from thick rust layers to fine particles on the surface of objects, including the cleaning of cultural relics, the removal of rubber dirt on the surface of tire molds, the removal of silicone oil contaminants on the surface of gold films, and the microelectronics industry. High precision cleaning. Laser cleaning technology really began in 2004, and began to invest a lot of manpower and material resources to strengthen the research on laser cleaning technology. In the past decade, with the development of advanced lasers, from inefficient and bulky carbon dioxide lasers to light and compact fiber lasers; from continuous output lasers to short pulse lasers with nanoseconds or even picoseconds and femtoseconds; from visible light output To the output of long-wave infrared light and short-wave ultraviolet light... lasers have developed by leaps and bounds in terms of energy output, wavelength range, or laser quality and energy conversion efficiency. The development of lasers has naturally promoted the rapid development of laser cleaning technology. Laser cleaning technology has achieved fruitful results in theory and application.
Mfundo zaukadaulo wa laser
Njira yakutsuka kwa laser imatengera mawonekedwe a kuwala kwa ma pulaneti opangidwa ndi laser ndipo kumadalira mawonekedwe a chithunzi omwe amachitika chifukwa cha kulumikizana pakati pa mtengo wokulirapo, kuwala kwapafupipafupi kwa laser ndi chosanjikiza. Mfundozi zitha kufotokozedwa mwachidule motere (Chithunzi 1)
A) mtengo womwe umatulutsidwa ndi laser umatengedwa ndi chosakanizira pamtunda kuti uchitidwe;
B) Kuperewera kwa mphamvu yayikulu kumapanga plasma yomwe ikukwera mofulumira (mpweya wambiri wosakhazikika), womwe umapanga mafunde owonongera;
C) Mphepo yamkuntho imasandutsira zinyalala kukhala zidutswa ndipo zimathetsedwa;
D) M'lifupi mwake mulitali muyenera kukhala waufupi mokwanira kuti mupewe kutentha komwe kumawononga malo osungidwawo;
(E) Kafukufuku akuwonetsa kuti pakakhala ma oxide pazitsulo, plasma imapangidwa pazitsulo.
Plasma imangopangika pamene mphamvu yachuma ili pamwamba penipeni, zomwe zimatengera wosakanikira wosanjikiza kapena oxide wosanjidwa. Mphamvu yotsetserayi ndiyofunika kwambiri pakuyeretsa koyenera pomwe mukuwonetsetsa chitetezo cha gawo lapansi. Pali gawo limodzi lachiwonekere lachiwonetsero cha plasma. Ngati mphamvu yamagetsi ipambana pakhomo, zinthu zoyambira ziziwonongeka. Kuti muchite kuyeretsa kogwira mtima pansi pa chikhazikitso chowonetsetsa chitetezo cha gawo lapansi, magawo a laser ayenera kusinthidwa malinga ndi momwe zinthu zilili, kotero kuti mphamvu yakuwala kwamphamvu ndiyomwe ili pakati pamagawo awiri.
