Taw qhia ntawm Optical brightener OB-1
Optical brightener OB-1,2,2- (4,4-distyreneyl) dibenzoxazole yog cov khoom siv daj crystalline nrog lub melting point ntawm 359-362 ℃. Nws yog insoluble hauv dej, tsis muaj ntxhiab, thiab muaj kev ua haujlwm ruaj khov. Qhov siab tshaj plaws nqus spectrum wavelength yog 374nm, thiab nws muaj zog fluorescence nrog fluorescence emission wavelength ntawm 434nm. Optical brightener OB-1 yog qhov ua kom pom kev zoo siv rau polyester fibers, thiab siv dav hauv cov yas xws li ABS, PS, HIPS, PC, PP, PE, EVA, thiab tawv PVC. Nws muaj cov nyhuv whitening zoo heev, zoo thermal stability, thiab ntxiv me ntsis ntxiv.
Optical brighteners tuaj yeem nqus pom tsis pom lub teeb ultraviolet (nrog lub wavelength ntawm kwv yees li 360-380nm) thiab hloov nws mus rau ntev wavelength xiav lossis ntshav pom lub teeb, yog li them nyiaj rau qhov tsis xav tau daj me ntsis hauv matrix. Nyob rau tib lub sijhawm, lawv muaj kev cuam tshuam pom lub teeb ntau dua li qhov teeb meem ntawm qhov teeb meem nyob rau hauv thaj tsam ntawm 400-600nm, ua rau cov khoom zoo li dawb, ci dua, thiab muaj zog dua.
Siv Optical brightener OB-1
Cov khoom no yog tsim rau cov khoom ua kom zoo nkauj thiab ci ntsa iab xws li PVC, PE, PP, ABS, PC, PA, thiab lwm yam. Nws muaj ntau npaum li cas, muaj zog adaptability, thiab zoo dispersibility. Cov khoom no muaj cov tshuaj toxicity tsawg heev thiab tuaj yeem siv rau cov yas yas siv rau hauv cov khoom ntim khoom noj thiab cov menyuam yaus cov khoom ua si. Nws tuaj yeem muab ntxiv thaum lub sijhawm ua haujlwm tom qab lossis polymerization, thiab cov khoom siv whitened muaj cov xim dawb thiab zoo heev thaum tshav kub kub thiab huab cua tsis kam. OB-1 kuj tseem tuaj yeem ua rau hauv cov tshuaj pleev xim rau textile whitening.
Qhov zoo ntawm Optical brightener OB-1
1.Los ntawm qhov kev xav ntawm qhov kub thiab txias:
Optical brightener OB-1 muaj qhov melting point ntau dua 350 ℃ thiab tam sim no yog qhov kub-resistant tshaj plaws ntawm tag nrho cov khoom kho qhov muag brightener. Rau cov thawj coj ua cov yas uas muaj kub-resistant, kho qhov muag brightener OB-1 yog qhov tsim nyog dua.
Raws li paub zoo, kev lag luam yas yog kev lag luam dav thiab muaj ntau hom kev lag luam nrog ntau hom thiab cov yam ntxwv. Cov txheej txheem tsim khoom kub ntawm cov khoom yas feem ntau yog qhov siab, qee qhov txawm tias ncav cuag tshaj 300 degrees Celsius. Tam sim no, tsuas yog kho qhov muag brightener OB-1 tuaj yeem tiv taus qhov kub thiab txias, uas kuj yog qhov zoo ntawm qhov muag teeb pom kev zoo OB-1.
2. Txiav txim los ntawm lub teeb fluorescent emitted
Cov khoom siv kho qhov muag sib txawv muaj cov xim sib txawv, qee qhov kho qhov muag pom kev ci ntsa iab emit xiav lub teeb, thaum lwm tus emit xiav xiav lub teeb. Feem ntau ntawm cov khoom siv raw hauv qhov xwm txheej yog xim daj, thiab lub teeb daj ua ke nrog lub teeb xiav ua rau lub teeb dawb. Yog li ntawd, optical brighteners nrog hnyav xiav lub teeb muaj fluorescence zoo dua thiab whitening teebmeem, thiab tus nqi ntxiv kuj tsawg dua.
Optical brightener OB-1 tuaj yeem muab faib ua theem ntsuab thiab daj theem ntawm qhov tsos. Cov fluorescence tawm los ntawm theem ntsuab yog biased rau xiav lub teeb, thaum lub fluorescence emission los ntawm lub daj theem yog biased rau xiav xiav lub teeb. Yog li, qhov no yog vim li cas cov neeg siv khoom feem ntau xaiv cov theem ntsuab ntawm optical brightener OB-1 niaj hnub no.
