Mayankho Otsuka ndi Laser: Kuthana ndi Mavuto Pakukonza Zinthu Zoopsa Kwambiri

Kuyeretsa pogwiritsa ntchito laser kwakhala njira yothandiza kwambiri komanso yochotsera zinthu molunjika popanda kukhudza. Komabe, pogwira ntchito ndi zinthu zobisika, ndikofunikira kuti kuyeretsa kukhale koyenera komanso kotetezeka. Nkhaniyi ikupereka njira yolongosoka yothanirana ndi mavuto omwe angakhalepo pofufuza mawonekedwe a zinthu, magawo a laser, ndi kapangidwe kake.

Njira Zowonongera ndi Njira Zothanirana ndi Zipangizo Zoopsa Kwambiri Poyeretsa ndi Laser

1. Zipangizo Zosavuta Kutenthetsa

Njira Yowonongeka: Zipangizo zomwe zimakhala ndi malo otsika osungunuka kapena kutentha koipa—monga pulasitiki kapena rabala—zimafewa, zimasungunuka, kapena kusintha chifukwa cha kutentha komwe kumawonjezeka panthawi yoyeretsa ndi laser.

Mayankho: (1) Pazinthu monga pulasitiki ndi rabala: Gwiritsani ntchito ma laser othamanga amphamvu pang'ono ophatikizidwa ndi mpweya wosagwira ntchito (monga nayitrogeni). Kutalikirana koyenera kwa mpweya kumathandiza kuti kutentha kusamayende bwino, pomwe mpweya wosagwira ntchito umathandiza kupatula mpweya, kuchepetsa okosijeni. (2) Pazinthu zokhala ndi machubu monga matabwa kapena ceramic: Ikani ma laser othamanga pang'ono, okhala ndi machubu afupi okhala ndi ma scan angapo. Kapangidwe ka mkati ka machubu kumathandiza kufalitsa mphamvu ya laser kudzera mu kuwunikira mobwerezabwereza, kuchepetsa chiopsezo cha kutentha kwambiri komwe kumachitika pamalopo.

2. Zipangizo Zophatikizana Zambiri

Njira Yowonongera: Kuchuluka kwa mphamvu zomwe zimayamwa pakati pa zigawo kungayambitse kuwonongeka kosayembekezereka kwa gawo lapansi kapena kupangitsa kuti chophimbacho chichotsedwe.

Mayankho: (1) Pa zitsulo zopakidwa utoto kapena zinthu zophatikizika: Sinthani ngodya ya laser kuti musinthe njira yowunikira. Izi zimathandizira kulekanitsa mawonekedwe pamene mumachepetsa kulowa kwa mphamvu mu substrate. (2) Pa zinthu zophimbidwa (monga nkhungu zophimbidwa ndi chrome): Gwiritsani ntchito ma laser a ultraviolet (UV) okhala ndi mafunde enaake. Ma laser a UV amatha kuchotsa chophimbacho popanda kutentha kwambiri, kuchepetsa kuwonongeka kwa zinthu zomwe zili pansi pake.

3. Zipangizo Zolimba Kwambiri ndi Zosalimba

Njira Yowonongera: Zipangizo monga galasi kapena silicon ya kristalo imodzi zimatha kukhala ndi ming'alu yaying'ono chifukwa cha kusiyana kwa kutentha kapena kusintha kwadzidzidzi kwa kapangidwe ka kristalo.

Mayankho: (1) Pazinthu monga galasi kapena monocrystalline silicon: Gwiritsani ntchito ma ultra-short pulse lasers (monga femtosecond lasers). Kuyamwa kwawo kosalunjika kumathandiza kusamutsa mphamvu musanayambe kugwedezeka kwa lattice, kuchepetsa chiopsezo cha ming'alu yaying'ono. (2) Pazinthu zopangidwa ndi ulusi wa kaboni: Gwiritsani ntchito njira zopangira beam-shaping, monga annular beam profiles, kuti muwonetsetse kuti mphamvu imagawidwa mofanana ndikuchepetsa kuchuluka kwa kupsinjika pa resin-fiber interfaces, zomwe zimathandiza kupewa kusweka.

Ma Industrial Chillers : Mnzake Wofunika Kwambiri Poteteza Zipangizo Pakutsuka ndi Laser

Ma chiller a mafakitale amagwira ntchito yofunika kwambiri pochepetsa chiopsezo cha kuwonongeka kwa zinthu zomwe zimachitika chifukwa cha kutentha komwe kumadza chifukwa cha kusungunuka kwa kutentha panthawi yoyeretsa pogwiritsa ntchito laser. Kuwongolera kutentha kwawo molondola kumatsimikizira mphamvu yokhazikika yotulutsa laser komanso ubwino wa kuwala pansi pa mikhalidwe yosiyanasiyana yogwirira ntchito. Kutaya kutentha bwino kumalepheretsa kutenthedwa kwambiri kwa zinthu zomwe zimakhudzidwa ndi kutentha, kupewa kufewa, kusungunuka kwa kaboni, kapena kusintha kwa kutentha.

Kuwonjezera pa kuteteza zipangizozi, ma chiller amatetezanso magwero a laser ndi zida zowunikira, zomwe zimawonjezera nthawi ya moyo wa zida. Popeza ali ndi zida zotetezera zomwe zimamangidwa mkati, ma chiller amafakitale amapereka machenjezo oyambirira komanso chitetezo chokha ngati zinthu zitasokonekera, zomwe zimachepetsa chiopsezo cha kulephera kwa zida kapena ngozi.

Mapeto

Mwa kuganizira mozama za katundu wa zinthu, magawo a laser, ndi njira zogwirira ntchito, nkhaniyi ikupereka njira zothandiza zoyeretsera laser m'malo omwe ali pachiwopsezo chachikulu. Njirazi cholinga chake ndi kuonetsetsa kuti kuyeretsa bwino komanso kuchepetsa kuwonongeka kwa zinthuzo—kupangitsa kuyeretsa laser kukhala kotetezeka komanso kodalirika pakugwiritsa ntchito kosavuta komanso kovuta.
