Quality Index
1. Maonekedwe: ufa wonyezimira wachikasu
2. Mthunzi: Blue Violet
3. Fluorescence intensity (yofanana ndi mankhwala wamba): 100,140,145,150
3. Chinyezi: ≤5%
5. Madzi osasungunuka kanthu: ≤0.5%
6. Fineness (sieve posungira mlingo kudzera 120 mauna muyezo sieve): ≤5%
Magwiridwe ndi Makhalidwe
1. Ndi anionic ndipo angagwiritsidwe ntchito mu kusamba komweko ndi anionic surfactants kapena dyes, non-ionic surfactants ndi hydrogen peroxide.
2. Sikoyenera kugwiritsidwa ntchito mu kusamba komweko ndi cationic surfactants kapena dyes.
3. The fulorosenti whitening wothandizira VBL ndi wokhazikika kwa inshuwalansi ufa.
4. Fluorescent lightener VBL sichigonjetsedwa ndi ayoni achitsulo monga mkuwa ndi chitsulo.
Kuchuluka kwa Ntchito
1. Amagwiritsidwa ntchito poyeretsa thonje ndi zinthu zoyera za viscose, komanso kuwunikira zinthu zowala kapena zosindikizidwa, zokhala ndi kuwala kwachangu, kuyanjana kwabwino kwa ulusi wa cellulose, katundu wamba, kusindikiza, utoto, utoto wa pad ndi Oyenera kusindikiza phala.
2. Fluorescent lightener VBL itha kugwiritsidwa ntchito poyeretsa vinylon ndi zinthu za nayiloni.
3. Amagwiritsidwa ntchito poyeretsa mafakitale a mapepala, zamkati kapena utoto.
Malangizo
1. M'makampani opanga mapepala, chothandizira choyera cha fulorosenti VBL chikhoza kusungunuka m'madzi ndikuwonjezeredwa ku zamkati kapena utoto.
M'makampani opanga mapepala, gwiritsani ntchito madzi nthawi 80 kuti musungunule chopangira choyera cha fulorosenti VBL ndikuwonjezera pazamkati kapena zokutira.Kuchuluka kwake ndi 0.1-0.3% ya kulemera kwa zamkati zowuma fupa kapena zokutira zouma.
2. M'makampani osindikizira ndi opaka utoto, chopangira choyera cha fulorosenti VBL chikhoza kuwonjezeredwa mwachindunji ku matope opaka utoto, ndipo angagwiritsidwe ntchito atatha kusungunuka m'madzi.
Mlingo
0.08-0.3%, chiŵerengero chosambira: 1:40, kutentha kwabwino kwambiri kopaka utoto: 60 ℃
Kusungirako ndi Kusamala
1. Ndi bwino kusunga fulorosenti whitening wothandizira VBL pamalo ozizira, owuma ndi kupewa kuwala.Nthawi yosungira ndi zaka 2.
2. Nthawi yosungirako ya fulorosenti whitening wothandizira VBL ndi kuposa 2 miyezi.Makristasi ochepa amaloledwa, ndipo zotsatira zogwiritsira ntchito sizidzakhudzidwa panthawi ya alumali.
3. VBL yowunikira imatha kusakanikirana ndi anionic ndi osakhala a ionic surfactants, mwachindunji, acidic ndi mitundu ina ya anionic, utoto, ndi zina zotero. Sizoyenera kugwiritsidwa ntchito mu kusamba komweko ndi utoto wa cationic, surfactants, ndi ma resins opangidwa.
4. Madzi abwino kwambiri ayenera kukhala madzi ofewa, omwe sayenera kukhala ndi ayoni achitsulo monga mkuwa ndi chitsulo ndi klorini yaulere, ndipo ayenera kukonzekera mwamsanga atagwiritsidwa ntchito.
5. Mlingo wa fluorescent whitening agent VBL uyenera kukhala woyenera, kuyera kumachepa kapena kutembenukira chikasu pamene kuli kochuluka.Ndibwino kuti mlingo sayenera kupitirira 0.5%.
