Optical brightener OB thiab Optical brightener OB-1 feem ntau yog siv rau hauv kev lag luam yas, ob qho tib si yog cov tshuaj dawb huv rau cov yas. Los ntawm cov npe, peb tuaj yeem pom tias lawv zoo sib xws, tab sis dab tsi yog qhov txawv ntawm lawv?
1. Txawv txawv:
Cov tsos ntawm Optical brightenerOByog zoo ib yam-dawb hmoov. Muaj ob hom Optical brightenerOB-1: OB-1 daj thiab OB-1 ntsuab. Lub teeb xim ntawm OB-1 daj yog xiav xiav lub teeb, thiab lub teeb xim ntawm OB-1 ntsuab yog xiav lub teeb. OB-1 ntsuab yog feem ntau siv hauv kev lag luam yas.
OB OB-1
2. Cov ntsiab lus melting sib txawv:
Lub melting point ntawm Optical brightener OB yog 200 ℃, uas yog qis dua lub melting point ntawm Optical brightener OB-1 los ntawm 360 ℃ (OB-1 yog cov feem ntau tshav kub-resistant whitening agent), uas loj txiav txim siab daim ntawv thov ntawm ob Optical. brighteners. Yog li, OB tsis haum rau cov khoom kub kub, thiab ntawm qhov tod tes, OB-1 tuaj yeem siv rau cov khoom siv uas yuav tsum tau ua haujlwm kub.
3. Dispersibility thiab stability: OB> OB-1
Ntawm no, nws yuav tsum tau muab sau tseg tias zoo dispersibility txhais tau hais tias cov khoom yog yooj yim dua soluble thiab uniform. Piv txwv li, xim thiab number case yuav tsum muaj siab dispersibility ntawm Optical brighteners; Kev ruaj ntseg zoo yog hais txog qhov tseeb tias cov khoom tsis tshua muaj kev tsiv teb tsaws thiab yellowing nyob rau theem tom ntej. Piv txwv li, qee cov khau uas tsis zoo yuav tshwm sim dawb thiab dawb huv thaum thawj zaug yuav, tab sis sai sai tig daj thiab tsis muaj xim. Qhov no qhia tias kev ruaj ntseg ntawm Optical brighteners tsis zoo.
Dispersion feem ntau txhais cov kev ruaj ntseg ntawm daim ntawv thov, thiab cov khoom uas muaj dispersibility zoo yuav muaj cov nyhuv whitening ntev, thiab yellowing ntawm cov khoom yuav qeeb heev. Optical brightener OB muaj kev cuam tshuam zoo dua thiab ruaj khov dua li OB-1, uas yog vim li cas nws thiaj li pom zoo kom siv OB hauv cov xim pleev xim vim OB tsis tshua muaj qhov tshwm sim daj uas yuav tshwm sim thaum ntxov ntawm OB-1.
4. Tus nqi yog qhov sib txawv loj tshaj ntawm OB thiab OB-1
OB yog kim dua OB-1, yog li cov neeg siv khoom siv Optical brightenerOB-1 yuav tsum sim xaiv OB-1. Rau cov neeg muas zaub uas yuav tsum tau tshwj xeeb, xws li high-end number case coatings thiab mos yas, nws raug nquahu kom tseem siv OB-1.
5. Kev siv:
OB: Cov yas mos (PVC), pob tshab yas, zaj duab xis, xim thiab number case, ntim khoom noj, cov khoom ua si menyuam yaus
OB-1: Yas tawv, kub kub, txiv hmab txiv ntoo pob tawb
