Hauv kev tsim khoom lag luam thiab cov khoom siv science, kev ua raws li kev txhim kho kom zoo nkauj kom zoo nkauj thiab kev ua haujlwm ntawm cov khoom lag luam yog ib txwm tsis xaus. Ib qho kev hloov tshiab uas tau txais cov traction loj yog kev siv kho qhov muag brighteners, tshwj xeeb hauv huab cua. Txawm li cas los xij, ib lo lus nug uas tau los txog yog seb puas muaj qhov brighteners ourés yog tib yam li tshuaj dawb. Kab lus no aims rau demystify cov lus no thiab tshawb lawv cov haujlwm, kev siv, thiab sib txawv.
Dab tsi yog optical brightener?
Kho qhov muag Brighteners, Kuj tseem hu ua fluorescent whitening cov neeg sawv cev (FWA), muaj cov sib xyaw uas nqus ultraviolet (UV) lub teeb thiab rov tso nws lub teeb xiav. Tus txheej txheem no ua rau cov khoom uas tuaj yeem tshwm ntsej muag dawb thiab ci rau tib neeg lub qhov muag. Kev ua kom tsis pom zoo yog siv nyob rau hauv ntau yam kev lag luam, suav nrog cov ntawv nyeem, tshuaj ntxuav tes thiab plastics.
Nyob rau hauv cov ntaub ntawv ntawm cov plastics, tus neeg muaj qhov muag muaj qhov muag tau ntxiv thaum lub sijhawm tsim khoom lag luam los txhim kho kev pom ntawm cov khoom kawg ntawm cov khoom kawg. Lawv yog cov khoom siv tau tshwj xeeb hauv kev ua cov khoom siv yas saib kom huv thiab muaj txiaj ntsig ntau, them nyiaj rau qee qhov kev npau taws uas yuav tshwm sim sijhawm.
Yuav ua li cas kho qhov muag brighteners ua haujlwm?
Qhov kev tshawb fawb tom qab tus neeg muaj txiaj ntsig kho qhov muag muaj nws cov hauv paus hauv fluorescence. Thaum ultraviolet teeb ntaus npoo ntawm cov khoom siv yas muaj cov khoom siv ua kom zoo nkauj, lub compound nqus lub teeb thiab rov muaj emits nws li pom lub teeb xiav. Qhov xiav lub teeb cancels tawm ib qho daj daj, ua rau cov yas saib cov hniav dawb thiab ntau dua.
Qhov ua tau zoo ntawmKho qhov muag BrightenersNyob ntawm ntau yam, suav nrog cov hom yas, qhov concentration ntawm brightenler, thiab cov kev tsim tshwj xeeb ntawm cov compound. Nquag kho qhov muag ci ntsa iab siv rau hauv cov plastics suav nrog cov dilbene derivatives, coumarins thiab benzoxzoles.
Daim ntawv thov Fluorescent whitening cov neeg sawv cev hauv huab plastics
Qhov muag tsis zoo yog siv dav hauv cov khoom yas, suav nrog:
1. Ntim khoom: ua cov ntim khoom pom kev pom kev pom thiab txhim kho cov tsos ntawm cov khoom sab hauv.
2. Cov khoom hauv yim neeg: xws li ntim, cov tais diav, rooj tog zaum, tswj kom huv thiab ci.
3. Cov ntu pib: Txhim kho qhov zoo nkauj ntawm sab hauv thiab sab nraud.
4. Electronics: Xyuas kom tau ib txoj kev sleek, niaj hnub saib hauv vaj tse thiab lwm yam.
Puas yog kho qhov muag ci ntsa iab tib yam li tshuaj dawb?
Teb luv luv yog tsis muaj; Kev ua kom tsis pom zoo thiab cov tshuaj kom dawb tsis zoo li qub. Thaum ob qho tib si tau siv los txhim kho cov tsos ntawm cov khoom, lawv ua haujlwm los ntawm kev sib txawv sib txawv thiab ua haujlwm sib txawv.
BLEK yog dab tsi?
Bleach yog tshuaj lom neeg feem ntau siv rau kev siv tshuaj tua kab thiab ntxuav kom huv. Feem ntau hom tshuaj dawb yog chlorine tshuaj dawb (sodium hypochlorite) thiab cov tshuaj oxygen (hydrogen peroxide). BLEX ua haujlwm los ntawm kev ua txhaum cov tshuaj lom neeg ntawm stains thiab pigments, tau tshem tawm cov xim los ntawm cov ntaub ntawv.
Qhov sib txawv tseem ceeb ntawm kev ua kom zoo nkauj tawg thiab tshuaj dawb
1. Mechanism ntawm Kev Ua:
- Kho kom zoo rau cov khoom siv kho tshiab: Ua rau cov ntaub ntawv tshwm ntsej muag hniav dawb thiab ci ntsa iab los ntawm kev nqus UV thiab rov ua kom pom lub teeb xiav.
- BLEA: Tshem tawm cov xim los ntawm cov ntaub ntawv los ntawm kev siv cov tshuaj los ntawm cov khoom siv thiab cov pigments.
2. Lub Hom Phiaj:
- Fluorescent White Frents: Siv feem ntau los txhim kho kev pom ntawm cov ntaub ntawv los ntawm kev ua rau lawv tshwm sim ntxhua khaub ncaws thiab ntau dua.
- Tshuaj dawb: siv rau kev ntxuav, tshuaj tua kab thiab kev tshem tawm stain.
3. Daim Ntawv Thov:
- Fluorescent whitening tus neeg sawv cev: feem ntau siv hauv plastics, textiles thiab xab npum.
- Tshuaj dawb: Siv hauv cov khoom siv ntxuav cov khoom siv, cov tshuaj ntxuav ntxhua khaub ncaws thiab cov tshuaj ntxuav kev lag luam.
4. Tshuaj Muaj Zog:
- Fluorescent Whites Cov neeg sawv cev: Feem ntau cov organic sib xyaw xws li stilbene derivatives, coumarins thiab benzoxzoles.
- BLEAFACANIC cov tebchaw xws li sodium hypochlorite (chlorine cugorite (chlorine sib xyaw ua ke xws li hydrogen peroxide (cov tshuaj oxygen (cov tshuaj oxygen
Kev Nyab Xeeb Kev Nyab Xeeb thiab Kev Txiav Txim Siab
Kho qhov muag Brightenersthiab tshuaj dawb rau txhua tus muaj lawv cov kev txhawj xeeb thiab ib puag ncig kev txhawj xeeb. Kev ua kom tsis pom zoo yog ntsuas kev nyab xeeb rau kev siv cov neeg siv khoom, tab sis muaj kev txhawj xeeb txog lawv cov kev cuam tshuam ntawm ib puag ncig thiab muaj peev xwm ntawm lub neej muaj dej. Tshuaj ntxuav kom dawb, cov tshuaj dawb tshwj xeeb, yog corrorine thiab tsim kev phom sij xws li cov tshuaj lom zem xws li cov tshuaj lom zem xws li cov neeg dioxins, uas muaj kev phom sij rau tib neeg kev noj qab haus huv thiab ib puag ncig.
Hauv kev xaus
Txawm hais tias kho qhov muag tshiab thiab ua kom dawb yuav tshwm sim zoo ib yam li lawv cov tshuaj ntxuav hniav dawb, lawv cov tshuab, thiab cov ntawv thov sib txawv. Kev thov kho qhov muag tau tshwj xeeb siv los txhim kho qhov kev pom ntawm kev pom ntawm cov yas thiab lwm cov ntaub ntawv los ntawm kev ua rau lawv pom cov hniav dawb thiab ci dua. Nyob rau hauv kev sib piv, tshuaj dawb yog lub tshuab nqus tsev ntxhua khaub ncaws siv los tshem cov stains thiab tshuaj tua kab mob.
Nkag siab cov kev sib txawv no yog qhov tseem ceeb rau cov tuam txhab tsim khoom, cov neeg siv khoom, thiab txhua tus neeg koom nrog cov ntaub ntawv kev tshawb fawb lossis kev tsim khoom. Los ntawm kev xaiv txoj cai compound rau txoj cai daim ntawv thov, peb tuaj yeem ua tiav qhov xav tau kev xav tau zoo thiab ua haujlwm tau thaum tsis muaj peev xwm cuam tshuam rau kev noj qab haus huv thiab ib puag ncig.
