II. Hauv -Qhov sib piv qhov tob ntawm cov yam ntxwv tseem ceeb
1. Cov tsos thiab ntxoov ntxoo txawv
OB: Lub teeb daj hmoov nrog ci xiav fluorescence.
OB-1: Feem ntau yellowish-ntsuab hmoov, muaj nyob rau hauv ob variants -
OB-1 Yellow: Bluish-Violet fluorescence
OB-1 Green: Blue fluorescence (OB-1 Green yog feem ntau siv hauv kev lag luam yas)
2. Kev sib piv Dispersibility
OB: Superior dispersibility- yooj yim dua thiab sib npaug faib rau hauv substrate. Rau cov tshuab uas muaj cov kev xav tau siab dispersibility xws li xim, inks, thiab coatings, OB muaj qhov zoo sib xws.
OB-1: Nruab nrab dispersibility, txawm tias cov txiaj ntsig txaus siab tuaj yeem ua tiav hauv feem ntau cov ntaub ntawv yas ua los ntawm kev sib xyaw ua ke.
3. Kev ruaj ntseg thiab huab cua tsis kam
OB: Zoo dua stability- tsis tshua muaj kev tsiv teb tsaws thiab yellowing thaum tom qab- siv theem, ua rau nws haum rau cov ntawv thov uas xav tau kev ua haujlwm siab.
OB-1: Kev ruaj ntseg tsis muaj zog heev - tuaj yeem pom kev tsiv teb tsaws lossis daj nyob rau hauv qee yam kev mob tshwj xeeb (txawm hais tias qhov no tsis yog qhov tseeb, thiab kev tswj xyuas kom zoo tuaj yeem txo cov teeb meem zoo li no).
4. Brightening Effect (Whiteness Value)
OB-1xa ibtseem ceeb dua whiteness tus nqidua li OB, muab cov teebmeem kev ci ntsa iab ntau dua - zoo tagnrho rau cov khoom siv siab - kawg nrog cov kev xav kom dawb huv.
OBmuab nruab nrab whiteness, txaus rau feem ntau cov pa siv.
5. Nqe sib piv
OB yog kim kim tshaj OB-1, nrog rau tam sim no kev lag luam tus nqi sib txawv tshaj 100%.
Keeb kwm: Thaum ntxov, tus nqi ntawm ob yam khoom zoo sib xws. Txawm li cas los xij, nyob rau xyoo tas los no, vim muaj kev tswj hwm ib puag ncig nruj thiab txwv cov khoom siv raw khoom, OB raw khoom lag luam tau ntsib cov khoom nruj, ua rau tus nqi nce ntxiv. Lub caij no, OB-1 cov saw hlau tseem nyob ruaj khov, thiab nws cov nqi tau txais txiaj ntsig tau dhau los ua qhov tseem ceeb.
