Daim ntawv thov
Optical brightener KCB yog ib qho ntawm cov khoom lag luam zoo tshaj plaws ntawm ntau cov fluorescent whitening agents.Cov nyhuv whitening muaj zog, ci xiav thiab ci xim, nws muaj cov cua sov zoo, huab cua tsis kam thiab tshuaj lom neeg ruaj khov.Nws yog tsuas yog siv rau kev ntxuav hniav dawb ntawm cov khoom siv yas thiab hluavtaws fiber ntau, thiab nws kuj muaj qhov pom tseeb ci ntsa iab ntawm cov khoom yas uas tsis yog ferrous.Nws kuj yog siv dav hauv ethylene / vinyl acetate (EVA) copolymer, uas yog ib qho zoo heev ntau yam ntawm optical brighteners hauv khau kis las.Nws kuj yog siv dav hauv PE, PP, PVC, PS, ABS, PMMA thiab lwm yam yas zaj duab xis, molding cov ntaub ntawv, txhaj tshuaj molding cov ntaub ntawv thiab polyester fibers.Nws kuj tseem muaj txiaj ntsig zoo rau kev ua kom dawb ntawm cov xim thiab cov xim ntuj.Qhov ntau yam no yog cov tshuaj lom tsawg tshaj plaws ntawm ntau hom tshuaj ntxuav hniav dawb.Tebchaws Asmeskas tau hais tias nws tuaj yeem siv rau cov khoom ntim khoom noj dawb.
Kev Siv Tshuaj
Rau cov yas los yog cov resins, qhov ntau npaum li cas yog 0.01-0.03%, uas yog, li ntawm 10-30 grams ntawm BC-111 fluorescent whitening tus neeg sawv cev yog ntxiv rau 100 kilograms ntawm cov khoom siv yas.Tus neeg siv tuaj yeem kho qhov ntau npaum li cas ntawm tus neeg sawv cev whitening raws li qhov yuav tsum tau ua ntawm whiteness.Yog hais tias ib qho ultraviolet absorber xws li titanium dioxide ntxiv rau cov khoom siv yas, qhov zoo tshaj plaws ntawm cov tshuaj ntxuav hniav dawb yuav tsum tau kho kom haum.
PE: 10-25g / 100kg yas raw khoom
