I-Optical brightener OB kanye ne-Optical brightener OB-1 zivame ukusetshenziswa embonini yepulasitiki, yomibili eyi-universal whitening agents yamapulasitiki. Kusukela emagameni, siyabona ukuthi afana kakhulu, kodwa yimuphi umehluko oqondile phakathi kwawo?
1. Ukubukeka okuhlukile:
Ukubukeka kwe-Optical brightenerOBimpushana emhlophe Efanayo. Kunezinhlobo ezimbili ze-Optical brightenerOB-1: OB-1 ophuzi no-OB-1 oluhlaza. Ukukhanya kombala we-OB-1 ophuzi ukukhanya okuluhlaza okwesibhakabhaka okunsomi, futhi ukukhanya kombala ka-OB-1 okuluhlaza kuwukukhanya okuluhlaza okwesibhakabhaka. I-OB-1 eluhlaza ivame ukusetshenziswa embonini yepulasitiki.
OB OB-1
2. Amaphuzu ancibilikayo ahlukene:
Indawo encibilikayo ye-Optical brightener OB ingu-200 ℃, ephansi kunephuzu lokuncibilika le-Optical brightener OB-1 ngo-360 ℃ (OB-1 i-ejenti ekwazi ukumelana nokushisa kakhulu), enquma kakhulu ukusetshenziswa kwe-Optical emibili. izikhanyisi. Ngakho-ke, i-OB ayifanele imikhiqizo yokushisa okuphezulu, futhi ngakolunye uhlangothi, i-OB-1 ingasetshenziselwa izinto ezidinga ukucutshungulwa kwezinga lokushisa eliphezulu.
3. Ukuhlakazeka nokuzinza : OB>OB-1
Lapha, kufanele kuqashelwe ukuthi i-dispersibility enhle isho ukuthi umkhiqizo uncibilika kalula futhi ufana. Isibonelo, upende noyinki kudinga ukuhlakazeka okuphezulu kwama-Optical brighteners; Ukuzinza okuhle kubhekisela eqinisweni lokuthi umkhiqizo awujwayele ukufuduka futhi ube phuzi esigabeni sakamuva. Isibonelo, ezinye izicathulo zekhwalithi ephansi zingase zibonakale zimhlophe futhi zihlanzekile lapho zithengwa okokuqala, kodwa maduzane ziphenduke zibephuzi futhi zishintshe umbala. Lokhu kukhombisa ukuthi ukuzinza kwama-Optical brighteners akulungile.
Ukusabalalisa kuchaza ngokuyinhloko ukuzinza kwesicelo, futhi imikhiqizo ene-dispersibility enhle izoba nemiphumela emhlophe ehlala isikhathi eside, futhi ukuphuzi komkhiqizo kuzohamba kancane kakhulu. I-Optical brightener OB inokuhlakazeka okungcono nokuzinza kune-OB-1, yingakho kunconywa ukuthi kusetshenziswe i-OB ezimbotsheni ze-inki ngoba i-OB ayijwayelene nesenzakalo sokuphuzi okungenzeka senzeke ezigabeni zokuqala ze-OB-1.

5. Ukusetshenziswa:
OB: Ipulasitiki ethambile (PVC), ipulasitiki esobala, ifilimu, upende noyinki, iziqukathi zokudla, amathoyizi ezingane
OB-1: Ipulasitiki eqinile, izinga lokushisa eliphezulu, ubhasikidi wezithelo
