Ko nga tikanga o te horoi a-taiao te nuinga o te wai, te wai totika, reagents matū, ngaru ultrasonic, me te mahi miihini. Heoi, ko nga tikanga horoi tenei he raru penei i te kino o te papa, te waahi kore mahi, te paru, te horoi horoi noa, me nga utu horoi. Na te kaha o te paru o te taiao, kei te kaha te maatauranga a nga kairangahau mai i nga tini whenua mo te penapena o te whakaoranga, te taiao me te hangarau horoi hou. No te mea te horoi horoi laser he maha nga painga o te hangarau penei i te iti o te kino ki nga papanga paparanga, te horoi totika, te kore kore me te aukati, ka whai hua ka whakamanahia e te ao wero me te umanga. Kaore i te feaa ko te tono hangarau horoi mo te horoi i te puehu ki te horoi i te paru i runga i nga papa whakarewa te tino nui o te tumanako.
Te hitori whanaketanga me te mana o tenei hangarau hangarau horoi
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.
Te parau tumu o te hangarau horoi horoi laser
Ko te mahinga o te horoi laser pulsed ka tiimata ki nga ahuatanga o te puku marama i hangaia e te laser me te tau kei runga i te tauhohenga photophysical i puta na te taunekeneke i waenga i te kurupae maama te-teitei, te laser poto poto me te papa tohatoha. Ko te maakete tinana e taea te whakarapopotohia e whai ake nei (Whakaahua 1)
A) Ko te kurupae i tukuna e te laser, ka uru te papa poke ki te mata ki te rongoa;
B) Ko te ngaronga nui o te kaha o te kaha o te hinu nui (he hau totoka tino kaha), e whakaputa ngaru ohorere ana;
C) Ka poipoihia te ngaru puhaka hei ruinga ka mutu;
D) Me whanui te whanui o te huringa maamaa kia kore ai e whakahekehia te wera, ka aukati i te papanga;
(E) E whakaatuhia ana e nga whakamatautau, i te wa kei te oxide i runga i te papanga whakarewa, ka puta te raarangi mai i te mata whakarewa.
Ka hangaia anake te Plasma i te wa e eke ake ai te taarua o te hiko ki runga ake o te paepae, e pa ana ki te paparanga o te paparanga o te paparanga oxide ranei ka tangohia. He mea nui tenei paanga mo te horoi tika i te wa e whakarite ana i te haumaru o te papanga ngarara. He whetu tuarua mo te ahua o te plasma. Mena te nui o te kaha o te pngao ki tenei paepae, ka pakaru te papanga turanga. Hei whakatutuki i te horoi tino pai i raro i te waahi o te whakarite kia ora te haumaru o te papanga tote, me whakatika nga tohu o te laser kia rite ki te ahuatanga, kia whakapiki i te whakapiki kaha o te pana marama i waenga i nga paepae rua.
