Fluorescent Whitening Agent (FWA)

Kufotokozera mwachidule:

Ndiwophatikizi wokhala ndi kuchuluka kwachulukidwe kokwanira, mwadongosolo la magawo 1 miliyoni mpaka 100,000, omwe amatha kuyera bwino magawo achilengedwe kapena oyera (monga nsalu, mapepala, mapulasitiki, zokutira).Imatha kuyamwa kuwala kwa violet ndi kutalika kwa 340-380nm ndikutulutsa kuwala kwa buluu ndi kutalika kwa 400-450nm, komwe kumatha kupanga bwino chikasu chobwera chifukwa cha kuwonongeka kwa zinthu zoyera.Ikhoza kusintha kuyera ndi kuwala kwa zinthu zoyera.The fulorosenti whitening wothandizira palokha ndi colorless kapena kuwala chikasu (wobiriwira) mtundu, ndipo chimagwiritsidwa ntchito kupanga mapepala, nsalu, zotsukira kupanga, mapulasitiki, zokutira ndi mafakitale ena kunyumba ndi kunja.Pali mitundu 15 yoyambira komanso mitundu pafupifupi 400 yamankhwala oyeretsa a fulorosenti omwe apangidwa ndi mafakitale.

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 zotsatira, 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 kowala kwambiri, ndipo styrene-triazine fluorescent whitening agent imapangitsa kuti nsalu ikhale yobiriwira pambuyo pogwiritsidwa ntchito mobwerezabwereza.Kuda, kuyera kumachepa.Insoluble mu chlorinated hydrocarbons, koma akhoza kumwazikana mwa iwo.The tinthu mankhwala a mankhwalawa ndi lalikulu pafupifupi tinthu kukula, amene ndi zachilengedwe 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.
