Ma Optical Brighteners akhala akugwiritsidwa ntchito limodzi ndi sopo kuyambira mu 1940. Ngakhale kuti ali ndi mlingo wochepa mu sopo, amapereka kuwala kodabwitsa komanso kowala, zomwe zimapangitsa kuti akhale chowonjezera chofunikira komanso chokondedwa kwambiri mumakampani opanga sopo.

Malinga ndi ziwerengero zosakwanira,40% ya opanga ma Optical brightener padziko lonse lapansipakadali pano ikugwiritsidwa ntchito mu gawo la sopo.

Nkhaniyi ikupereka mwachidule za Optical Brighteners, kuphatikizapo tanthauzo lake, njira yoyeretsera, kupanga ndi kugwiritsa ntchito, mlingo woyenera, komanso chofunika kwambiri, chitetezo chake pakugwiritsa ntchito—nkhani yofunika kwambiri kwa ogula padziko lonse lapansi.

1. Kodi ndi chiyaniZowunikira Zowala?

Optical Brighteners ndi mtundu wa utoto wa Optical. Pogwiritsa ntchito kuwala kwa ultraviolet (UV), amatulutsa kuwala kwabuluu ndi violet komwe kumawonjezera kuwala kwachikasu pamwamba pa substrate, motero amapanga kuwala koyera.

Amadziwikanso kutizowunikira kuwala or utoto woyera wa kuwala, amagwiritsa ntchito mphamvu yowonjezera ya utoto wowala kuti ayeretse, aunikire, ndikuwonjezera kuwala kwa zinthu zoyera kapena zowala monga nsalu, mapepala, ndi mapulasitiki.

2. Njira Yoyeretsera Ma Optical Brighteners

Monga momwe tafotokozera, njira yoyeretsera ya Optical Brighteners ndi iyi:

Pokhala ndi kuwala kwa dzuwa (komwe kuli kuwala kwa UV), amayamwa kuwala kwa UV komwe kumakhala ndi kutalika kwa 340 ~ 380nm ndipo amatulutsa kuwala kwa Optical mu mtundu wa buluu-violet wooneka (410 ~ 460nm). Kuwala kumeneku komwe kumatuluka kumasakanikirana ndi kuwala kwachikasu pa substrate kuti kupange mawonekedwe oyera.

Kuwala kooneka ndi gawo lowala kumawonjezeka, zomwe zimapangitsa kuti gawo lowala ndi loyera likhale loyera kwambiri.

3. Kugwiritsa Ntchito Zowunikira Zowala

Optical Brighteners amagwiritsidwa ntchito kwambiri m'mafakitale ndi m'magawo osiyanasiyana, kuphatikizapo nsalu, kupanga mapepala, sopo, mapulasitiki, zokutira, inki, zikopa, zotsutsana ndi zinthu zabodza, komanso kuzindikira laser. Kufalikira kwa ntchito padziko lonse lapansi m'mafakitale kukuwonetsedwa mu tebulo ili m'munsimu:

4. N’chifukwa Chiyani Mumawonjezera Zounikira za Optical ku Zotsukira Madzi?

(1) Kulimbitsa Magwiridwe Abwino Otsuka

Nsalu zoyera kapena zopepuka zopangidwa ndi ulusi wachilengedwe komanso wopangidwa zimakhala zachikasu ndipo zimaoneka ngati zatha ntchito mobwerezabwereza. Nsalu zikachapidwa, ma Optical Brighteners omwe ali mu sopo amamatira pamwamba pa nsalu, kuyeretsa ndi kuunikira zinthu zotsukidwa, ndikubwezeretsa nsalu zakale zachikasu kukhala zoyera, zowala komanso zatsopano.zimakweza mawonekedwe onse ochapiracha mankhwala oyeretsera.

(2) Kuwongolera Maonekedwe a Zinthu Zotsukira Madzi

Ma Optical Brighteners amawonjezera bwino kuyera kwa sopo wothira zovala kapena sopo,kukulitsa mawonekedwe a zinthu zotsukira ndi kukweza mtundu wa zinthu zomwe zimagwiritsidwa ntchito.

5. Zowunikira Zodziwika Bwino za Detergents

Kusankha Optical Brighteners ndikofunikira kwambiri pakupanga sopo. Kutengera ndi zaka zambiri zomwe zagwiritsidwa ntchito, DSD acid bis-triazine ndi distyryl biphenyl Optical Brighteners zimapereka magwiridwe antchito abwino kwambiri.

Pakati pa izi,CI Optical Brightener 351ndiCI Optical Brightener 71ndi mitundu yomwe imagwiritsidwa ntchito kwambiri padziko lonse lapansi—yomwe imadziwikanso kutiCBS ndi CXT ya Optical Brightener, mitundu iwiri ikuluikulu yogwiritsidwa ntchito kwambiri mumakampani opanga sopo ku China ndipo yadziwika padziko lonse lapansi.

6. Mlingo Woyenera wa Ma Optical Brighteners mu Detergents

Zambiri sizili bwinoPonena za mlingo wa Optical Brighteners mu sopo. Kuchuluka koyenera kumatsimikiziridwa ndi zinthu monga kapangidwe ka sopo, kagwiritsidwe ntchito, ndi mtundu weniweni wa Optical brightener.

Kuwala kwachikasu pa nsalu zotsukidwa ndi kochepa, kotero kuchuluka kwa kuwala kwa buluu-violet komwe kumafunika kuti kukhale kofanana ndi kuwalako kumakhala kochepa. Pamene kuchuluka kwa Optical Brighteners pa nsalu kukuwonjezeka, mphamvu ya kuwala kwa buluu-violet komwe kumatulutsa kumawonjezeka, zomwe zimapangitsa kuti nsaluyo ikhale yoyera pang'onopang'ono.

Pamene kuchuluka kwa kuwala kwa buluu-violet kukafika pamlingo woyenera, mphamvu ya kuwala kwa buluu-violet komwe kumatulutsa kumatsutsana ndi kuwala kwachikasu pa nsalu—Iyi ndiye mfundo yayikulu yoyeretsa kwambiriKuonjezera mlingo m'malo mwake kungayambitse kuchepa kwa kuyera.

Khalidweli likugogomezera kufunika kolamulira mlingo molondola. Ku Ulaya ndi ku United States, mlingo woyenera wa Optical Brighteners mu zotsukira suti ndi wosiyana.kuyambira 0.05% mpaka 0.5%.

7. Chitetezo cha Zowunikira Zowala Pogwiritsa Ntchito Detergent

Chitetezo cha Optical Brighteners ndi chinthu chomwe chimadetsa nkhawa kwambiri ogula, komanso chimayambitsa kukayikira kosafunikira komanso nkhawa. Kwa Optical Brightener CBS ndi CXT—mitundu iwiri yomwe imagwiritsidwa ntchito kwambiri mumakampani opanga sopo—akatswiri a poizoni ndi zachilengedwe padziko lonse lapansi achita kafukufuku wasayansi wozama pa nyama zoyesera ndi anthu odzipereka kuti aone momwe zilili zotetezeka.

Maphunzirowa akufotokoza za poizoni woopsa, poizoni pakhungu, kuyabwa, kukhudzidwa ndi majini, poizoni wobwerezabwereza, poizoni woyambitsa khansa, kuchulukana kwa maselo m'thupi, komanso kuchuluka kwa zinthu zomwe zimapezeka m'mitsinje ndi m'nthaka. Kuphatikiza apo, kuyerekezera ndi kuchepetsa kunachitika pazochitika zomwe anthu angakumane nazo, kuchuluka kwa poizoni wopezeka, komanso malire a poizoni wopezeka m'thupi.

Mapeto ake ndi omveka bwino komanso otsimikizika:

1. Deta yaposachedwa kuchokera ku European Chemicals Agency (ECHA) ikutsimikizira kuti Optical Brighteners yogwiritsira ntchito sopo ndiosati zinthu za PBT (Zopitirira, Zokhazikika, Zoopsa) kapena vPvB (Zopitirira kwambiri, Zokhazikika kwambiri).

2. Owala Owala ndisizinaphatikizidwepamndandanda wa utoto woletsedwa woperekedwa ndi European Union ndi International Association for Research and Testing in the Field of Textile Ecology (Oeko-Tex).

3.Bungwe la European Chemical Industry Council (CEFIC) ndi mabungwe adziko lonse a sopo ndi zotsukira sopo akutsimikiza kuti Optical Brighteners yogwiritsira ntchito sopo ndi yotetezeka komansosizingawononge thanzi la anthu kapena chilengedwe.

4. Bungwe la Japan Soap and Detergent Association (JSDA) latsimikiza kuti Optical Brighteners yogwiritsira ntchito sopo ndi yothandiza kwambiri.chiopsezo chochepa kwambiriku thanzi la anthu ndi chilengedwe.

Chidule ichi chikupereka kumvetsetsa kokwanira komanso kolondola kwa Optical Brighteners ndi momwe amagwiritsidwira ntchito mu sopo. Ngati mukufuna kudziwa zambiri zokhudza zinthu zathu za Optical brightener, chonde musazengereze kutero.Lumikizanani nafenthawi iliyonse—timapereka mayankho apamwamba, ogwirizana komanso okonzedwa mwamakonda malinga ndi zosowa zanu zopangira sopo.
