Scope ntawm daim ntawv thov
Fluorescent brightener PF-3 feem ntau yog siv rau kev ua kom zoo nkauj thiab ci ntsa iab PVC, polystyrene, polyacrylate, polyester zaj duab xis, siab thiab tsis tshua muaj siab polyethylene, ABS, plexiglass, daim npav lag luam, ntawv qib siab, thiab lwm yam.
Kev noj tshuaj
Daim ntawv thov txheej txheem: Sib tov cov optical brightener PF-3 nyob rau hauv cov yas xaiv ntawm 0.03-0.1% ntawm qhov hnyav ntawm cov yas, thiab tom qab ntawd txuas ntxiv nrog cov txheej txheem yas siv.Nco ntsoov ntawm no tias nws yuav tsum sib tov zoo.
Fluorescent brightener PF-3 tuaj yeem yaj nrog cov yas yas thiab tom qab ntawd milled rau hauv qhov kev ncua nrog peb yob los tsim ib tug niam cawv.Tom qab ntawd do hauv PF-3 yas fluorescent whitening tus neeg sawv cev raug ncua tsis tu ncua thaum lub sijhawm ua, thiab ua kom nws nyob ntawm qhov kub thiab txias (lub sijhawm nyob ntawm qhov kub), feem ntau ntawm 120～150 ℃ rau li 30 feeb, thiab 180～190 ℃ rau li 1 feeb.Uas yog los tsim ib tug zoo whitening thiab brightening nyhuv.Los yog sib tov txhua yam ntawm raw cov ntaub ntawv ua ntej, thiab thaum kawg ntxiv PF brightener, sib tov tusyees ntawm 160 ℃ rau li 5 feeb, thiab ces yob rau hauv cov duab.
