Chiyambi cha Optical Brightener OB-1
Chowunikira cha Optical OB-1,2,2- (4,4-distyreneyl) dibenzoxazole ndi chinthu chachikasu cha kristalo chokhala ndi malo osungunuka a 359-362 ℃. Sichisungunuka m'madzi, sichinunkha, ndipo chimagwira ntchito bwino. Kutalika kwa mafunde a mayamwidwe ndi 374nm, ndipo chili ndi kuwala kwamphamvu ndi kutalika kwa mafunde a fluorescence emission a 434nm. Chowunikira cha Optical OB-1 ndi chowunikira champhamvu cha optical chomwe chimagwiritsidwa ntchito popanga ulusi wa polyester, ndipo chimagwiritsidwa ntchito kwambiri mu mapulasitiki monga ABS, PS, HIPS, PC, PP, PE, EVA, ndi PVC yolimba. Chili ndi mphamvu yabwino kwambiri yoyeretsa, kukhazikika kwa kutentha, komanso kuwonjezera pang'ono.
Zowunikira kuwala zimatha kuyamwa kuwala kosaoneka kwa ultraviolet (komwe kumakhala ndi mafunde a pafupifupi 360-380nm) ndikukusintha kukhala kuwala kwakutali kwa mafunde abuluu kapena ofiirira, motero zimathandizira chikasu chochepa chomwe sichinafunike mu matrix. Nthawi yomweyo, zimawunikira kuwala kowoneka bwino kuposa mafunde oyambirira a incident omwe ali ndi mafunde a 400-600nm, zomwe zimapangitsa kuti chinthucho chiwoneke choyera, chowala, komanso chowala kwambiri.
Kugwiritsa ntchito Optical brightener OB-1
Chogulitsachi ndi choyenera kuyeretsa ndi kuunikira mapulasitiki monga PVC, PE, PP, ABS, PC, PA, ndi zina zotero. Chili ndi mlingo wochepa, chosinthika kwambiri, komanso chosavuta kufalitsa. Chogulitsachi chili ndi poizoni wochepa kwambiri ndipo chingagwiritsidwe ntchito kuyeretsa mapulasitiki omwe amagwiritsidwa ntchito poika chakudya ndi zoseweretsa za ana. Chikhoza kuwonjezedwa mukamakonza kapena polima, ndipo zinthu zoyerazo zimakhala zoyera kwambiri komanso zimateteza kutentha ndi nyengo. OB-1 ikhozanso kupangidwa kukhala phala loyeretsa nsalu.
Ubwino wa Optical Brightener OB-1
1. Kuchokera pamalingaliro a kukana kutentha:
Chowunikira cha OB-1 chili ndi malo osungunuka opitirira 350 ℃ ndipo pakadali pano ndiye chowunikira kwambiri chomwe chimateteza kutentha pakati pa zinthu zonse zowunikira. Kwa akuluakulu opanga mapulasitiki osatentha kwambiri, chowunikira cha OB-1 ndicho choyenera kwambiri.
Monga momwe zimadziwikira, makampani opanga pulasitiki ndi makampani akuluakulu komanso osiyanasiyana okhala ndi mitundu ndi makhalidwe osiyanasiyana. Kutentha kwa zinthu zambiri zopangidwa ndi pulasitiki kumakhala kokwera, zina zimafika madigiri Celsius oposa 300. Pakadali pano, OB-1 yokha ndi yomwe imatha kupirira kutentha kotere, komwe ndi ubwino wa OB-1 yopangira kuwala.
2. Kuweruza kuchokera ku kuwala kwa fluorescent komwe kumatulutsa
Zipangizo zosiyanasiyana zowunikira kuwala zimakhala ndi mitundu yosiyanasiyana, zina zowunikira kuwala zimatulutsa kuwala kwabuluu, pomwe zina zimatulutsa kuwala kofiirira kwabuluu. Zinthu zambiri zachilengedwe ndi zachikasu, ndipo kuwala kwachikasu kophatikizidwa ndi kuwala kwabuluu kumapanga kuwala koyera. Chifukwa chake, zowunikira kuwala zokhala ndi kuwala kwabuluu kolemera zimakhala ndi kuwala kwabwino komanso kuyera bwino, ndipo kuchuluka komwe kumawonjezeredwa kumakhala kochepa.
Chowunikira kuwala OB-1 chingagawidwe m'magulu awiri: gawo lobiriwira ndi gawo lachikasu malinga ndi mawonekedwe. Kuwala komwe kumatuluka ndi gawo lobiriwira kumayenderana ndi kuwala kwabuluu, pomwe kuwala komwe kumatuluka ndi gawo lachikasu kumayenderana ndi kuwala kwabuluu wofiirira. Chifukwa chake, ichi ndichifukwa chake makasitomala ambiri amasankha gawo lobiriwira la chowunikira kuwala OB-1 masiku ano.
Ndife ogulitsa akuluakulu ku China, ngati mukufuna mtengo kapena zambiri, tikukulandirani kuti mulankhule nafe pa:
