Kukhala ndi fluorescence sikutanthauza kuwonjezera fulorosenti whitening wothandizira CBS-X

Tikudziwa kuti zovala zakale zoyera ndi zosindikizidwa, wowuma wankhungu, ndi njere nthawi zambiri zimatulutsa kuwala konyezimira, kumapangitsa anthu kumva kukhala achikasu.Ngati mulingo woyenera wa fluorescent whitening wothandizira wawonjezedwa panthawiyi, izifulorosenti whitening wothandiziraimatulutsa kuwala kwa buluu kapena kofiirira pambuyo poyamwa ndi kuwala kwa ultraviolet, kupanga mtundu wofananira ndi kuwala kwachikasu kotengedwa ndi chinthucho chokha, potero kuchotsa chodabwitsa choyambirira cha "chikasu" ndikupanga zovala ndi zida zosindikizidwa zomwe poyambirira zimawoneka zachikale. kuwoneka oyera ngati atsopano (chidziwitso: kuwonjezera zowunikira za fulorosenti ku wowuma wankhungu ndipo njere sizololedwa!).Iyi ndiye mfundo yoyera ya fluorescent whitening agents.Mwachidule, fulorosenti whitening wothandiziraCBS-Xamagwiritsa ntchito utoto wowoneka bwino kuyera, kuwunikira, kapena kuwunikira zinthu zoyera kapena zowala.Simakumana ndi mankhwala aliwonse ndi chinthucho, koma zimangodalira mawonekedwe owoneka kuti awonjezere kuyera kwa chinthucho.Chifukwa chake, chowunikira choyera cha fulorosenti CBS-X imadziwikanso kuti "optical whitening agent" kapena "dye yoyera".

 Kodi kukhalapo kwa fluorescence kukutanthauza kuwonjezeredwa kwa fluorescent whitening agent CBS-X?

Monga tafotokozera pamwambapa, chochitika cha fluorescence ndizochitika zakuthupi zomwe zingayambike kuchokera kuzinthu zachibadwa za fulorosenti, monga fluorescein mu ziphaniphani;Pakhozanso kukhala zinthu zosiyanasiyana za fulorosenti zochokera kuzinthu zopanga kupanga, monga inki za fulorosenti, zokutira za fulorosenti, zolembera za fulorosenti, mapulasitiki a fulorosenti, ndi zipangizo zina zomwe zikuganiziridwa kuti ndi zipangizo zogwiritsira ntchito fulorosenti, komanso zipangizo zoyera za fulorosenti.Fluorescent whitening agents ndi mtundu wapadera chabe wa zinthu za fulorosenti zomwe zimakhala zoyera komanso zowala pakati pa zinthu zosiyanasiyana zovuta za fulorosenti.Chifukwa chake, kunena mosamalitsa, zinthu za fulorosenti sizifanana ndi zowunikira za fulorosenti, ndipo kuyang'ana zochitika za fulorosenti sikutanthauza kuwonjezeredwa kwa zowunikira za fulorosenti !!!

 Fluorescence phenomenon ≠ kupezeka kwafulorosenti whitening wothandizira CBS-X

 Zowunikira za fluorescent zimapanga zochitika za fluorescence (pamafunde enaake)

 Monga zowonjezera zakudya, mitundu yosiyanasiyana ya zowunikira za fulorosenti ndizovuta.Malinga ndi kagwiritsidwe ntchito, amagawidwa kukhala zowunikira za fulorosenti zopangira mapepala, mapulasitiki ndi zida zopangira, nsalu, zotsukira, inki, zomatira, ndi zina.

 Malinga ndi gulu la ma ionic, zowunikira za fulorosenti zitha kugawidwanso kukhala zowunikira zopanda ionic, zowunikira za anionic, zowunikira za cationic, ndi zowunikira za amphoteric.

Malinga ndi kapangidwe ka mankhwala, amatha kugawidwa m'magulu asanu: mtundu wa stilbene, mtundu wa coumarin, mtundu wa pyrazoline, mtundu wa benzoxazole, ndi mtundu wa phthalimide imide.

Malinga ndi kusungunuka kwamadzi, amatha kugawidwa m'magulu awiri: osungunuka m'madzi ndi osasungunuka.Madzi osungunuka a fulorosenti amagwiritsidwa ntchito makamaka poyeretsa mapepala, zokutira, zotsukira zovala, ndi nsalu za thonje, pomwe madzi osasungunuka a fulorosenti amagwiritsidwa ntchito kwambiri popanga zinthu zoyera monga ulusi wamankhwala ndi mapulasitiki.

 Pakadali pano, pali masinthidwe amankhwala pafupifupi 15 ndi zowunikira zopitilira 400 za fulorosenti.Pambuyo pa zaka zambiri akusesa mchengawo, wina wachotsedwa kale, ndipo tsopano pali mitundu yambirimbiri yamitundu yomwe imagwiritsidwa ntchito mofala yomwe ikupangidwabe ndikugwiritsidwa ntchito padziko lonse lapansi.
