Zokolola za fluorescence quantum ndizokwera, ndipo mlingo wake ndi gawo limodzi mwa magawo anayi okha a stilbene-triazine mtundu wa fluorescence self-enhancing agent.Hue wofiirira (kuwala kwa buluu wabuluu), kugonjetsedwa kwambiri ndi chlorine bleaching, hydrogen peroxide bleaching ndi asidi amphamvu, alkali wamphamvu, akhoza kuonjezera kuyera kwa ufa wochapira ndi sopo ndi sopo, kusintha maonekedwe ake.Kuyenda bwino, kutentha pang'ono, kusamba pang'ono kusiyana ndi kusamba m'manja ndi makina ochapira yunifolomu kuyera kwa zovala, sikudzatulutsa mawanga.Wamphamvu whitening kwenikweni, m'madzi ozizira ndi madzi ofunda pa mapadi ulusi.Polyamide.Mapuloteni CHIKWANGWANI.Thonje ndi zinthu zina zoyera za fulorosenti zimakhala ndi mphamvu yodziwonjezera yokha, pamene zoyera za fulorosenti zimakhala ndi zoyera zochepa pa kutentha kochepa.Liwiro loyera limakhala lofulumira, ndipo nsaluyo imatha kufika kuyera kwambiri mu nthawi yochepa kwambiri.Ili ndi dzuwa louma komanso lonyowa kwambiri komanso kukana kutulutsa thukuta, ndipo diphenyl triazine fluorescent whitening agent ndi yosavuta kuwola panthawi yowumitsa nsalu yotsuka, ndipo imapangitsa kuti nsaluyo ikhale yachikasu pansi pa ntchito ya thukuta.Pambuyo kutsuka mobwerezabwereza, zotsatira zake zimakhala bwino, kuchapa koyera kwambiri, kuchapa kwambiri, ndipo styrene-triazine fluorescent whitening agent imapangitsa kuti nsalu ikhale yobiriwira ikagwiritsidwa ntchito mobwerezabwereza.Kuda, kuyera kumachepa.Insoluble mu chlorinated hydrocarbons, koma amatha kumwazikana mwa iwo.The tinthu mankhwala a mankhwalawa ndi lalikulu pafupifupi tinthu kukula, amene ndi chilengedwe wochezeka mankhwala.
Gwiritsani ntchito
Amagwiritsidwa ntchito kwambiri mu ufa wochapira wapamwamba kwambiri.Super concentrated liquid detergent, itha kugwiritsidwanso ntchito mu sopo.Kuyera kwa sopo kungagwiritsidwenso ntchito muzofewetsa nsalu ndi kumaliza.Itha kugwiritsidwa ntchito yokha kapena kuphatikiza ndi mitundu ina ya fluorescent whitening agent malinga ndi zosowa zosiyanasiyana.Thonje amapakidwa utoto chifukwa cha kutopa ndi pad, ubweya wa nkhosa amapaka ndi kutopa, ndipo nayiloni amapakidwa utoto chifukwa cha kutopa.Njira yokhazikitsira utoto wopaka utoto wotentha.Acid pad utoto kapena zosungunulira pad utoto njira, amathanso utoto silika, kufulumira kwabwino.Kugwirizana kwa thonje ndi kotsika mpaka pakati, ndipo kuyanjana kwa ubweya, silika ndi nayiloni ndikwambiri.
Mlingo wovomerezeka
① Mu zotsukira zopangira, tikulimbikitsidwa kuwonjezera motere:
| Mtundu | mlingo/% | Mtundu | mlingo/% |
| Wamba wochapira ufa | 0.05-0.25 | Sopo wakuchapira | 0.05-0.15 |
| Ufa wochapira wokhazikika | 0.10-0.40 | Sopo wakuchimbudzi | 0.05-0.15 |
| Zotsukira zamadzimadzi | 0.05-0.40 | Chochapa chofewa | 0.02-0.05 |
| Wothandizira kuyeretsa mafakitale | 0.20-1.00 | Emulsio | 0.05-0.15 |
② Kugwiritsa ntchito pa kusindikiza ndi kudaya: malo achikasu osambira a 1:20 ndi 0.3%, ndipo chikasu cha 1:40 ndi 0.5%.

Zogulitsa zachilengedwe, zimapewa kuwononga fumbi pakagwiritsidwe ntchito, zosavuta kugwiritsa ntchito, zosungunuka mosavuta m'madzi, zimatha kusakanikirana ndi madzi mulimonse.
Gwiritsani ntchito
Oyenera zotsukira madzi.Sopo.Sopo ndi zinthu zina zochapira zitha kugwiritsidwanso ntchito mwachindunji pa thonje.Kuwala koyera kwa bafuta, silika, ubweya, nayiloni ndi nayiloni kutentha kutentha.
Mlingo wovomerezeka
Ikhoza kuwonjezeredwa mwachindunji ku slurry ya detergent, ndipo ingagwiritsidwenso ntchito mwachindunji kuyeretsa nsalu, ndipo kuyamwa kwa ultraviolet ndikosiyana kwambiri.
