Lasers tau siv dav hauv ntau qhov chaw, los ntawm cov tshuaj mus rau kev lag luam, thiab lawv txoj kev nyab xeeb tau dhau los ua qhov kev txhawj xeeb tseem ceeb. Cov ntaub ntawv acrylic tau nrov rau lawv cov pob tshab thiab ua haujlwm ntev, ua rau lawv tsim nyog rau cov ntawv thov uas pom qhov tseem ceeb. Hauv cov ntsiab lus no, cov lus nug tshwm sim: cov txiv kab ntxwv acrylic puas tuaj yeem tiv thaiv lasers? Cov lus qhia dav dav no txhawm rau tshawb xyuas cov khoom ntawm acrylic, nws cov kev faib tawm, cov khoom siv, cov ntawv thov, thiab cov kev xav tseem ceeb thaum siv nws ua ib qholaser tiv thaiv cov khoom.
Acrylic yog dab tsi?
Acrylic, feem ntau hu ua PMMA (Polymethyl methacrylate), yog ib qho hluavtaws polymer ua los ntawm acrylic acid thiab methacrylic acid. Nws paub txog nws qhov tseeb, uas yog piv rau iav, tab sis nrog cov txiaj ntsig ntxiv ntawm kev ua kom ruaj khov dua, sib dua hauv qhov hnyav, thiab yooj yim rau kev tsim ntau yam duab. Acrylic cov qauv tshuaj txiav txim siab nws cov yam ntxwv ntawm lub cev, xws li tiv thaiv UV teeb, cuam tshuam lub zog, thiab huab cua.
Classification ntawm Acrylic
Cov ntaub ntawv acrylic tuaj yeem raug cais raws li lawv cov txheej txheem tsim khoom, qhov hnyav molecular, thiab daim ntawv thov:
Cam khwb cia acrylic: Ua los ntawm casting thiab kho cov kua monomer hauv pwm. Nws yog lub npe hu rau nws siab clarity thiab uniformity.
Extruded acrylic: Ua los ntawm cov txheej txheem extrusion, ua rau cov khoom muaj zog tab sis tsis pom qhov pom tseeb dua piv rau cam khwb cia acrylic.
Optical-qib acrylic: Tshwj xeeb tsim rau daim ntaub ntawv uas xav tau siab transparency thiab meej optical zog.
Khoom siv
Acrylic cov khoom tseem ceeb uas ua rau nws muaj txiaj ntsig zoo rau kev tiv thaiv laser suav nrog:
Lub teeb kis tau tus mob: Acrylic kis mus txog 92% ntawm lub teeb pom kev, ua rau nws pob tshab heev.
Refractive index: Qhov ntsuas ntawm qhov ceev ntawm lub teeb qeeb qeeb hauv cov khoom siv. Acrylic muaj qhov ntsuas qis dua li iav, txo qhov ua tau ntawm tag nrho cov kev xav sab hauv.
Absorption thiab reflection: Cov xim sib txawv ntawm acrylic nqus thiab pom lub teeb sib txawv vim pigmentation.
Daim ntawv thov ntawm Acrylic hauv Laser Protection
Acrylic yog siv nyob rau hauv ntau hom ntawm laser kev ruaj ntseg cov cuab yeej, xws li:
Laser tsom iav tsom iav
Laser tiv thaiv qhov rais
Cov teeb meem hauv cov chaw ua haujlwm laser
Enclosures rau high-power laser systems
Nws lub peev xwm los thaiv cov teeb meem wavelengths thaum tso cai rau pom lub teeb kom dhau los ua rau nws yog ib qho khoom siv zoo tshaj plaws rau cov ntawv thov no.
Xim Acrylic thiab Laser Interaction
Cov xim acrylics tuaj yeem txhim kho qhov nqus lossis kev xav ntawm lub teeb ntawm lub teeb. Piv txwv li, txiv kab ntxwv acrylic muaj cov xim uas nqus tau qee zaus ntawm lub teeb. Yog hais tias lub wavelength ntawm lub laser coincides nrog lub absorption spectrum ntawm cov txiv kab ntxwv xim, nws yuav ua tau zoo attenuate los yog thaiv lub laser beam. Txawm li cas los xij, qhov no kuj yog nyob ntawm yam xws li kev siv thiab lub sijhawm ntawm laser raug, nrog rau cov tuab thiab zoo ntawm cov khoom siv acrylic.
Kev txiav txim siab thaum siv Acrylic rau Laser Protection
Qhov tshwj xeeb wavelength: Tsis yog txhua cov ntaub ntawv acrylic zoo tiv thaiv txhua hom lasers. Kev xaiv ntawm cov khoom yuav tsum yog laser wavelength tshwj xeeb.
Thickness thiab ntom: Cov ntawv tuab acrylic tuaj yeem muab kev tiv thaiv zoo dua tab sis kuj tseem tuaj yeem cuam tshuam qhov pom.
Kev ruaj ntseg zoo: Tsuas yog siv cov ntaub ntawv acrylic uas ua tau raws li cov qauv thoob ntiaj teb rau kev nyab xeeb laser.
Kev Kho: Kev tshuaj xyuas tsis tu ncua rau khawb lossis deformations yog qhov tsim nyog los tswj kev ua haujlwm zoo.
Ib puag ncig yam tseem ceeb: Ntev ntev raug rau lub hnub ci tuaj yeem degrade acrylic, cuam tshuam nws cov kev ua tau zoo.
Xaus
Txiv kab ntxwv acrylic yeej muaj peev xwm muab kev tiv thaiv ib co laser wavelengths yog xaiv thiab siv kom tsim nyog. Nws cov xim tuaj yeem txhim kho qhov nqus ntawm lub teeb frequencies, muab qib kev nyab xeeb tiv thaiv laser raug. Txawm li cas los xij, nws yog ib qho tseem ceeb uas yuav tau xav txog kev sib raug zoo ntawm acrylic nrog rau cov laser wavelengths tshwj xeeb hauv kev siv, ua raws li cov qauv kev nyab xeeb thoob ntiaj teb laser, thiab tswj cov khoom siv kom ntseeg tau tias muaj txiaj ntsig zoo. Los ntawm kev ua li ntawd, ib tus tuaj yeem siv cov txiaj ntsig kev tiv thaiv ntawm cov xim acrylics hauv laser ib puag ncig kom nyab xeeb thiab ua tau zoo.
