Cov ntaub ntawv acrylic yog dav siv. Lawv pheej yig thiab muaj qhov zoo ntawm laser nqus. Lawv tuaj yeem siv los ua txhua yam ntawm cov khoom, suav nrog txhua yam ntawm cov paib, khoom plig thiab khoom plig.
Feem ntau cov neeg feem ntau xaiv cov pob tshab acrylic vim nws nrov heev thiab siv tau yooj yim. Cov pob tshab acrylic no feem ntau yog carved nrog carbon dioxide laser, uas yog txiav txim raws li cov yam ntxwv ntawm lub teeb. Lub wavelength ntawm carbon dioxide laser yog 9.2-10.8 μ m. Carbon dioxide laser kuj tseem hu ua molecular laser.
Txhawm rau siv cov ntaub ntawv laser engraving acrylic, peb yuav tsum xub nkag siab txog kev faib tawm ntawm cov ntaub ntawv. Acrylic feem ntau yog hais txog cov yas thermal ua los ntawm ntau hom. Acrylic phaj muab faib ua ob pawg: casting phaj thiab extrusion phaj raws li cov txheej txheem ntau lawm.
1. Acrylic casting board: siab molecular hnyav, zoo heev nruj, lub zog thiab zoo heev tshuaj tsis kam. Cov phaj no yog tus cwj pwm los ntawm kev ua haujlwm me me, qhov sib piv tsis tau yooj yim hauv cov xim thiab cov nyhuv zoo nkauj, ua tiav cov khoom tshwj xeeb thiab haum rau ntau lub hom phiaj tshwj xeeb. (thaum laser engraving, cam khwb cia acrylic yuav hloov mus rau hauv cov khoom txias raws li nyob rau hauv ntau yam kev cai daim ntaub ntawv. Nws tuaj yeem molded rau hauv ntau cov duab thiab ntau thiab tsawg, thiab nws yog feem ntau siv los ua khoom plig vim nws zoo optical zoo.
2.Acrylic extruded phaj: piv nrog cam khwb cia phaj, extruded phaj muaj qis dua molecular hnyav thiab tsis muaj zog txhua yam khoom. Txawm li cas los xij, qhov no yog qhov tsim nyog rau kev khoov thiab thermoforming, thiab yog qhov tsim nyog rau lub tshuab nqus tsev nqus nqus molding sai sai thaum cuam tshuam nrog cov phaj loj. Nyob rau tib lub sij hawm, lub thickness kam rau ua ntawm extruded phaj yog me dua li ntawm cam khwb cia phaj.
Nws yog ib qho yooj yim los ua extruded acrylic dua cam khwb cia acrylic, uas ua rau extruded acrylic pheej yig dua. Tsis tas li ntawd, lub extruded acrylic laser engraving yog huv si thiab du, thiab ntug yog nplaim polished. Laser engraving cov khoom zoo li meej heev, tsis zoo li lub frosted tsos tom qab casting acrylic engraving. Nws kuj yog softer thiab yooj yim rau lo thaum lub sij hawm teb engraving.
Cov nyhuv ntawm laser engraving acrylic yog qhov zoo tshaj plaws ntawm lub zog qis thiab kev kub ceev. Yog tias koj cov khoom siv acrylic muaj txheej txheej lossis lwm yam khoom siv ntxiv, thov ua kom lub zog los ntawm 10%, tab sis ceev ceev ntawm kev siv ntawm cov xim tsis muaj acrylic. Qhov no muab ntau zog rau lub laser txiav cov xim. Cov ntaub ntawv sib tham yuav txiav txim siab qhov kev teeb tsa zoo tshaj plaws rau koj lub laser. Txawm li cas los xij, yog tias siv cov cam khwb cia acrylic, koj tuaj yeem kos ntawm qhov zaus ntawm 10000 - 20000 Hz, thiab yog tias siv cov acrylic extruded, koj tuaj yeem xav carve ntawm qis zaus ntawm 2000 - 5000 Hz. Tsawg zaus ua rau cov pulses qis dua, ua rau lub zog pulse los yog txo lub zog tas li hauv acrylic acid. Qhov tshwm sim no ua rau muaj qhov kub tsawg, nplaim taws tsawg thiab qeeb txiav ceev.
