Nta

Anionic, tiv taus PH4.5-11.

1. Cov fluorescence khaus, zoo heev whitening nyhuv, thiab zoo lub teeb ceev ceev;

2. Yooj yim soluble, zoo acid thiab alkali tsis kam, nrog cov nyhuv whitening zoo dua VBL hauv pH ntau ntawm 4.5-7;

3. Hom anionic, siv tau rau tib lub da dej nrog anionic lossis nonionic surfactants.

Daim ntawv thov

Optical Brightener BA feem ntau yog siv rau hauv pulp brightening, nto sizing thiab txheej, thiab lwm yam, nrog siab acid kuj. Nws yog thawj qhov kev xaiv los tsim cov ntawv uas yuav tsum muaj qhov ci ntsa iab.

Kev lag luam ntawv: Siv rau pulp whitening, nto sizing, thiab txheej txheej txheem txheej. Nws nta sai sai thiab zoo acid kuj. Nws cov nyhuv whitening yog tshwj xeeb tshaj yog nyob rau hauv acidic tej yam kev mob ntawm pH 4.5-7. Nws tau thov kom muaj kev ci ntsa iab zoo dua li cov khoom lag luam VBL ib txwm, thiab tsis tshua muaj xim daj thaum lub sijhawm.

Kev lag luam textile: Haum rau cov paj rwb, ntaub pua chaw, txhob lo lo ntxhuav, nylon (polyamide), thiab cellulosic fibers. Nws kuj tseem siv tau rau cov tshuaj dawb huv - cov ntaub xim

Kev siv tshuaj

1.Thaum ci nyob rau hauv cov ntaub so ntswg, kho qhov muag brightener BA yuav tsum tau ntxiv ua ntej alum lossis cationic auxiliary agent; ntau npaum li cas: 0.05-0.4% (ntawm cov pulp qhuav).
2. Hauv qhov loj me, nws tuaj yeem ua haujlwm nrog CMC, PVA, hmoov txhuv nplej siab, lossis anionic lossis cationic hluavtaws sizing tus neeg sawv cev.
3. Hauv txheej txheej, nws tuaj yeem siv tau rau txhua theem ntawm txheej txheej txheej hauv daim ntawv ntawm cov tshuaj aqueous tom qab yaj.
