Isingeniso se-Optical brightener OB-1
I-Optical brightener OB-1,2,2- (4,4-distyreneyl) i-dibenzoxazole iyi-crystalline ephuzi enendawo yokuncibilika engu-359-362 ℃. Ayincibiliki emanzini, ayinaphunga, futhi isebenza kahle. Ubude be-spectrum yokumunca obuphezulu bungu-374nm, futhi inokukhanya okunamandla okunobude be-fluorescence emission obungu-434nm. I-Optical brightener OB-1 iyi-optical brightener esebenza kahle esetshenziselwa imicu ye-polyester, futhi isetshenziswa kabanzi kumapulasitiki afana ne-ABS, PS, HIPS, PC, PP, PE, EVA, kanye ne-PVC eqinile. Inomphumela omuhle kakhulu wokwenza mhlophe, ukuzinza okuhle kakhulu kokushisa, kanye nokufakwa okuncane.
Izibani zokukhanya ezikhanyayo zingamunca ukukhanya okungabonakali kwe-ultraviolet (okunobubanzi be-wavelength obungaba ngu-360-380nm) bese zikuguqula kube ukukhanya okude okuluhlaza okwesibhakabhaka noma okunsomi okubonakalayo, ngaleyo ndlela kuhlawulele okuphuzi okuncane okungafuneki ku-matrix. Ngesikhathi esifanayo, zibonisa ukukhanya okubonakalayo kakhulu kunobude be-wavelength bokuqala obuphakathi kuka-400-600nm, okwenza umkhiqizo ubonakale umhlophe, ukhanya, futhi ukhanya kakhudlwana.
Ukusetshenziswa kwe-Optical brightener OB-1
Lo mkhiqizo ufanelekela ukwenza amapulasitiki abe mhlophe futhi akhanye njenge-PVC, PE, PP, ABS, PC, PA, njll. Unomthamo ophansi, ukuguquguquka okunamandla, kanye nokuhlakazeka okuhle. Lo mkhiqizo unobuthi obuphansi kakhulu futhi ungasetshenziswa ukwenza amapulasitiki abe mhlophe asetshenziswa ekupakisheni ukudla kanye namathoyizi ezingane. Ungangezwa ngesikhathi sokucubungula noma ukwenziwa i-polymerization, kanti izinto ezimhlophe zimhlophe kakhulu futhi zimelana kahle nokushisa nesimo sezulu. I-OB-1 ingenziwa futhi ibe yi-paste yokwenza amapulasitiki abe mhlophe.
Izinzuzo ze-Optical brightener OB-1
1. Ngokombono wokumelana nokushisa:
I-OB-1 yokukhanyisa ukukhanya inendawo yokuncibilika engaphezu kuka-350 ℃ futhi okwamanje iyiyona emelana nokushisa kakhulu phakathi kwayo yonke imikhiqizo yokukhanyisa ukukhanya. Kubaphathi abakhiqiza amapulasitiki amelana nokushisa okuphezulu, i-OB-1 yokukhanyisa ukukhanya ifaneleka kakhulu.
Njengoba kwaziwa kahle, imboni yepulasitiki iyimboni ebanzi futhi ehlukahlukene enezinhlobo eziningi nezici. Izinga lokushisa lenqubo yokukhiqiza lemikhiqizo eminingi yepulasitiki liphezulu kakhulu, eminye ifinyelela ngisho nangaphezu kwama-degree Celsius angu-300. Njengamanje, i-OB-1 yokukhanyisa optical kuphela engamelana namazinga okushisa aphezulu kangaka, okuyinzuzo futhi ye-OB-1 yokukhanyisa optical.
2. Ukwahlulela ngokukhanya kwe-fluorescent okukhishwe
Imikhiqizo ehlukene yokukhanyisa ukukhanya kwe-optical inemibala ehlukene, eminye yokukhanyisa ukukhanya kwe-optical ikhipha ukukhanya okuluhlaza okwesibhakabhaka, kanti eminye ikhipha ukukhanya okuluhlaza okwesibhakabhaka onsomi. Iningi lezinto zokusetshenziswa zemvelo ziphuzi, kanti ukukhanya okuphuzi okuhlanganiswe nokukhanya okuluhlaza okwesibhakabhaka kukhiqiza ukukhanya okumhlophe. Ngakho-ke, okukhanyisa ukukhanya kwe-optical okunokukhanya okuluhlaza okwesibhakabhaka okunzima kunemiphumela engcono ye-fluorescence kanye ne-whitening, futhi inani elingeziwe nalo lincane.
I-OB-1 yokukhanyisa ukukhanya ingahlukaniswa ibe yisigaba esiluhlaza kanye nesigaba esiphuzi ngokwendlela ebukeka ngayo. I-fluorescence ekhishwa yisigaba esiluhlaza ithambekele ekukhanyeni okuluhlaza okwesibhakabhaka, kanti i-fluorescence ekhishwa yisigaba esiphuzi ithambekele ekukhanyeni okuluhlaza okwesibhakabhaka okunsomi. Ngakho-ke, yingakho amakhasimende amaningi ekhetha isigaba esiluhlaza se-OB-1 yokukhanyisa ukukhanya kulezi zinsuku.
