Cov nplooj ntawv PC (polycarbonate) yuav raug kev laus vim yog hluav taws xob ultraviolet, yog li PC sheet manufacturers tau siv ntau txoj hauv kev los daws qhov teeb meem no txhawm rau txhawm rau txuas lub neej kev pabcuam ntawm daim ntawv.Tam sim no, txoj kev ua tau zoo tshaj plaws thiab muaj txiaj ntsig zoo yog ntxiv cov khoom siv ultraviolet (abbreviated li UV cov ntaub ntawv) rau cov khoom.Raws li cov txheej txheem ntau lawm, muaj peb txoj hauv kev ntxiv cov khoom siv UV: sib xyaw ntxiv txoj kev, txheej txheej thiab co-extrusion txoj kev.
1.Txoj kev sib xyaw ntxiv
Ib qho piv txwv ntawm cov khoom siv UV (kwv yees li 5%) yog tov rau hauv cov khoom siv PC, thiab tom qab ntawd melted thiab extruded ntawm qhov kub thiab txias.Txawm li cas los xij, feem ntau ntawm cov phiaj xwm ua tiav los ntawm txoj kev no tseem raug rau lub hnub, yog li kev laus ntawm cov phaj saum npoo tseem tsis tuaj yeem zam.
2. Txheej txheej
Txheej txheej ntawm cov khoom siv UV rau saum npoo ntawm lub rooj tsavxwm.Txawm li cas los xij, vim qhov tsis zoo ntawm PC thiab lwm yam khoom siv, cov dej nag tuaj yeem yooj yim ntxuav cov txheej ntawm lub rooj tsavxwm tom qab kev teeb tsa.Tsis tas li ntawd, txiav txim siab tias lub rooj tsavxwm tuaj yeem raug puas tsuaj thaum lub sijhawm khaws cia thiab kev thauj mus los, ob sab ntawm lub rooj tsavxwm tau them nrog cov yeeb yaj kiab tiv thaiv thaum tsim khoom.Cov yeeb yaj kiab tiv thaiv yuav tsum tau muab tshem tawm tom qab kev teeb tsa, thiab vim tias cov yeeb yaj kiab tiv thaiv yog nplaum, ntau cov khoom siv UV coated rau saum npoo yuav lo thaum lub sij hawm tsim kua muag, yog li cov nyhuv tiag tiag kuj tsis zoo.
3. Coextrusion
Tam sim no, txoj kev tshaj lij tshaj plaws hauv ntiaj teb yog txoj kev co-extrusion.Nyob rau hauv txoj kev no, cov khoom tseem ceeb ntawm PC thiab cov khoom siv UV yog melted thiab extruded ntawm qhov kub thiab txias nyob rau hauv ib tug extruder, merged nyob rau hauv pwm, thiab ces ntws los ntawm cov khiav nyob rau hauv lub pwm los tsim ib tug tuab tiv thaiv txheej ntawm lub PC.Txawm li cas los xij, kev hloov pauv ntawm qhov kub thiab txias, ceev, siab, thiab lwm yam hauv kev tsim khoom tiag tiag siv txoj kev no yuav cuam tshuam rau kev faib cov khoom siv UV rau saum npoo ntawm daim ntawv, ua rau lub thickness tsis sib npaug ntawm qhov dav ntawm daim ntawv.
