Polycarbonate Sheets UV Resistant

Cov txheej txheem tseem ceeb ntawm UV tsis kam rau cov nplooj ntawv Polycarbonate suav nrog hybrid ntxiv thiab UV co-extruded ntxiv.

Hybrid ntxiv yuav tsum sib tov lub UV absorber nrog raw khoom ntawm PC granules thiab muab tso rau hauv lub tshuab txhaj tshuaj molding tom qab sib tov. Txoj kev no yog qhov yooj yim, tab sis cov nyhuv yog txwv, vim tias nws tsis tuaj yeem tsim cov txheej txheem UV zoo rau ntawm lub rooj tsavxwm PC, uas yuav ua rau kev laus thiab yellowing ntawm lub rooj tsavxwm tom qab ob peb xyoos.
UV co-extrusion hom ntxiv yog los ntawm cov txheej txheem extrusion sib xyaw hauv cov pwm, hauv cov txheej txheem extrusion ncaj qha rau saum npoo ntawm PC tsis kam phaj los tsim UV extrusion txheej. Cov txheej txheem UV-tiv taus tsim los ntawm txoj kev no yog ib yam thiab ntom, uas cuam tshuam qhov kev laus ntawm cov nplooj ntawv Polycarbonate.
Tsis tas li ntawd, cov nplooj ntawv ob sab UV-tiv taus ua tiav qhov theoretical siab tshaj plaws lub neej ncua sij hawm thiab tseem tiv thaiv cov nplooj ntawv Polycarbonate nyob rau ntau qhov xwm txheej, muab lawv lub neej ntev dua.

Yangzhou Chengsen tau tsim mature ob-sided anti-ultraviolet PC endurance panels rau canopies, siv Hitz khoom vaj huam sib luag ntau lawm kab los ntawm Nyiv. Lub tshuab ua yeeb yaj kiab sib xyaw co-extrusion tuaj yeem ua rau cov txheej txheem los tiv thaiv ultraviolet thiab PC cuam tshuam-resistant txheej tag nrho ywj siab thiab sib koom ua ke, nrog lub thickness txog li 50μm. Raws li kev poob txhua xyoo ntawm kwv yees li 2-3μm, lub neej kev pabcuam yog ntau tshaj kaum xyoo. Ntxiv mus, cov khoom siv uas muaj cov khoom siv ntau dua li cov roj hluav taws xob ntau dua li cov roj hluav taws xob, uas tuaj yeem npog cov nplaim hluav taws xob, uas tuaj yeem tiv thaiv tus PC UV puas.
