Zomwe Muyenera Kudziwa Zokhudza Kuyeretsa Laser
Laser yoyamba padziko lapansi idapangidwa mu 1960 ndi wasayansi waku America Pulofesa Theodore Harold Mayman pogwiritsa ntchito kafukufuku ndi chitukuko cha ruby, Kuyambira pamenepo ukadaulo wa laser umapindulitsa anthu m'njira zosiyanasiyana.Kuchulukitsidwa kwaukadaulo wa laser kumapangitsa kukula kwachangu kwa sayansi ndi ukadaulo pantchito zachipatala, kupanga zida, kuyeza mwatsatanetsatane komanso kupanganso uinjiniya kumathandizira kupita patsogolo kwa anthu.
Kugwiritsa ntchito laser m'munda woyeretsa kwachita bwino kwambiri.Poyerekeza ndi njira zachikhalidwe zoyeretsera monga mikangano yamakina, corrosion yamankhwala komanso kuyeretsa pafupipafupi kwa ultrasound, kuyeretsa kwa laser kumatha kuzindikira ntchito yodziwikiratu ndi maubwino ena monga kuyendetsa bwino, mtengo wotsika, kuwononga chilengedwe, kusawonongeka kwa zinthu zoyambira komanso kukonza kosavuta kwa kufalikira kwa ntchito.Kuyeretsa kwa laser kumakwaniritsadi lingaliro la kukonza zobiriwira, zachilengedwe komanso njira yodalirika komanso yothandiza yoyeretsa.
Mbiri ya Laser Cleaning Development
Chiyambireni kubadwa kwa lingaliro laukadaulo woyeretsa laser m'ma 1980, kuyeretsa kwa laser kwatsagana ndi kupita patsogolo kwaukadaulo wa laser ndi chitukuko.M’zaka za m’ma 1970, wasayansi wina wa ku United States, dzina lake J. Asums, anaika patsogolo maganizo oti agwiritse ntchito ukadaulo woyeretsa wa laser poyeretsa ziboliboli, zojambula ndi zinthu zina zachikhalidwe.Ndipo zatsimikizira mwakuchita kuti kuyeretsa kwa laser kuli ndi gawo lofunikira pakuteteza zikhalidwe zachikhalidwe.
Mabizinesi akuluakulu omwe amagwira ntchito yopanga zida zoyeretsera za Laser akuphatikizapo Adapt Laser ndi Laser Clean All ochokera ku United States, El En Goup ochokera ku Italy ndi Rofin waku Germany, ndi zina zambiri. .Mwachitsanzo, EYAssendel'ft et al.Poyamba adagwiritsa ntchito laser yothamanga kwambiri yothamanga kwambiri ya CO2 mu 1988 poyesa kuyesa konyowa, kugunda kwamphamvu kwa 100ns, mphamvu imodzi yamagetsi 300mJ, panthawiyo anali mtsogoleri padziko lonse lapansi.Kuyambira 1998 mpaka pano, kuyeretsa kwa laser kwachitika modumphadumpha.R.Rechner et al.adagwiritsa ntchito laser kuyeretsa wosanjikiza wa okusayidi pamwamba pa aluminiyamu aloyi ndikuwona kusintha kwamitundu ndi zomwe zili mkati musanayambe komanso pambuyo poyeretsa poyang'ana maikulosikopu ya elekitironi, ma dispersive spectrometer, infuraredi sipekitiramu ndi X-ray photoelectron spectroscopy.Akatswiri ena agwiritsa ntchito laser ya femtosecond pakuyeretsa ndi kusunga zolemba ndi zolemba zakale, ndipo ili ndi ubwino woyeretsa kwambiri, kutayika kwazing'ono komanso kuwonongeka kwa ulusi.
Masiku ano, kuyeretsa kwa laser kukuchulukirachulukira ku China, ndipo MimoWork yakhazikitsa makina otsuka am'manja a laser amphamvu kwambiri kuti athandize makasitomala kupanga zitsulo padziko lonse lapansi.

Mfundo Yoyeretsera Laser
Laser kuyeretsa ndi kugwiritsa ntchito makhalidwe a mkulu kachulukidwe mphamvu, controllable malangizo ndi convergence luso la laser kuti mphamvu yomanga pakati zoipitsa ndi masanjidwewo awonongeke kapena zoipitsa mwachindunji vaporized njira zina decontaminate, kuchepetsa mphamvu yomanga ya zoipitsa ndi masanjidwewo, ndiyeno kukwaniritsa kuyeretsa pamwamba pa workpiece.Pamene zoipitsa pamwamba pa workpiece kuyamwa mphamvu ya laser, gasification awo mofulumira kapena pompopompo matenthedwe kukula adzagonjetsa mphamvu pakati zoipitsa ndi gawo lapansi pamwamba.Chifukwa cha kuchuluka kwa kutentha kwamphamvu, the
Njira yonse yoyeretsera laser imatha kugawidwa m'magawo anayi:
1. laser gasification kuwonongeka,
2. kuchotsa laser,
3. Kuwonjeza kwa kutentha kwa tinthu tating'onoting'ono,
4. kugwedezeka kwa matrix pamwamba ndi kutsekedwa koipitsa.
Kusamala kwina
Zachidziwikire, mukamagwiritsa ntchito ukadaulo wa laser woyeretsa, chidwi chimayenera kuperekedwa ku malo oyeretsera laser a chinthu chomwe chiyenera kutsukidwa, ndikusankhidwa koyenera kwa laser wavelength, kuti mukwaniritse bwino kuyeretsa.Kuyeretsa kwa laser kumatha kusintha kapangidwe kake ndikuyika kwa gawo lapansi popanda kuwononga gawo lapansi, ndipo kumatha kuwongolera kuuma kwa gawo lapansi, kupititsa patsogolo magwiridwe antchito ake a gawo lapansi.Kuyeretsa kumakhudzidwa makamaka ndi mawonekedwe a mtengowo, magawo akuthupi a gawo lapansi ndi zinthu zonyansa komanso kuyamwa kwa dothi ku mphamvu yamtengo.
