Txij li xyoo 1940 los, cov tshuaj ua kom ci ntsa iab tau siv ua ke nrog cov tshuaj ntxuav khaub ncaws. Txawm hais tias lawv muaj cov tshuaj ntxuav khaub ncaws tsawg, lawv ua rau cov khaub ncaws dawb thiab ci ntsa iab zoo kawg nkaus, ua rau lawv yog cov khoom siv tseem ceeb thiab nyiam siv hauv kev lag luam tshuaj ntxuav khaub ncaws.

Raws li cov ntaub ntawv tsis tiav,40% ntawm lub ntiaj teb kev tsim khoom siv ua kom pom kev ci ntsa iabtam sim no siv rau hauv kev lag luam ntxuav khaub ncaws.

Tsab xov xwm no muab ib qho kev piav qhia luv luv txog Optical Brighteners, suav nrog lawv cov lus txhais, cov txheej txheem ua kom dawb, kev tsim khoom thiab kev siv, cov tshuaj pom zoo, thiab qhov tseem ceeb tshaj plaws, lawv txoj kev nyab xeeb hauv kev siv - qhov kev txhawj xeeb tseem ceeb rau cov neeg siv khoom thoob ntiaj teb.

1. Dab tsi yogCov Khoom Siv Ci Ntxuam Qhov Muag?

Cov tshuaj ua kom ci ntsa iab yog ib hom tshuaj zas xim Optical. Nyob rau hauv lub teeb ultraviolet (UV), lawv tso tawm lub teeb xiav thiab violet uas ua kom tiav lub teeb daj ntawm qhov chaw substrate, yog li ua tiav cov nyhuv dawb.

Kuj tseem hu uacov tshuaj ua kom pom kev zoo or dawb Optical dyes, lawv siv cov xim kho qhov muag los ua kom dawb, ci ntsa iab thiab txhim kho qhov ci ntsa iab ntawm cov khoom dawb lossis cov xim sib dua xws li ntaub, ntawv, thiab yas.

2. Kev Ua Kom Dawb Huv ntawm Cov Khoom Ua Kom Dawb Huv

Raws li lawv cov lus txhais, cov txheej txheem ua kom dawb ntawm Optical Brighteners yog raws li nram no:

Thaum raug tshav ntuj (uas muaj lub teeb UV), lawv nqus lub teeb UV nrog lub wavelength ntawm 340 ~ 380nm thiab tso tawm lub teeb pom kev zoo hauv qhov pom xiav-violet (410 ~ 460nm). Lub teeb no sib xyaw nrog lub teeb daj ntawm lub substrate kom tsim cov nyhuv dawb.

Qhov kev cuam tshuam ntawm lub teeb pom kev los ntawm lub substrate ci ntsa iab raug txhim kho, uas ua rau lub substrate dawb thiab ci ntsa iab ntau dua.

3. Daim Ntawv Thov ntawm Optical Brighteners

Cov tshuaj ua kom ci ntsa iab siv dav hauv ntau yam lag luam thiab thaj chaw, suav nrog cov ntaub, kev ua ntawv, cov tshuaj ntxuav tes, cov yas, cov tshuaj pleev xim, cov kua mem, tawv, kev tiv thaiv kev cuav, thiab kev kuaj pom laser. Kev faib tawm thoob ntiaj teb ntawm daim ntawv thov los ntawm kev lag luam tau qhia hauv lub rooj hauv qab no:

4. Vim li cas thiaj yuav tsum ntxiv cov tshuaj ua kom ci ntsa iab rau hauv cov tshuaj ntxuav khaub ncaws?

(1) Txhim kho kev ntxuav kom huv si

Cov ntaub dawb lossis xim dawb uas ua los ntawm cov xov ntuj thiab cov xov hluavtaws feem ntau yuav daj thiab zoo li qub tom qab siv thiab ntxuav ntau zaus. Thaum cov ntaub raug ntxuav, cov tshuaj Optical Brighteners hauv cov tshuaj ntxuav khaub ncaws yuav nqus rau ntawm qhov chaw ntawm cov ntaub, ua kom cov ntaub ntxuav dawb thiab ci ntsa iab, rov qab ua kom cov ntaub daj, qub rov qab zoo li qub, ci ntsa iab thiab zoo li tshiab. Qhov noua rau pom kev zoo dua qub ntawm kev ntxuav tag nrhontawm cov khoom ntxuav tais diav.

(2) Txhim kho qhov tsos ntawm cov khoom ntxuav tes

Cov tshuaj ua kom pom tseeb ua rau cov tshuaj ntxhua khaub ncaws lossis xab npum dawb dua,txhim kho qhov pom kev ntawm cov khoom ntxuav khaub ncaws thiab txhim kho lawv cov khoom qib.

5. Cov Tshuaj Ci Ntxuam Rau Cov Tshuaj Ntxuav Khaub Ncaws

Kev xaiv cov tshuaj ua kom ci ntsa iab yog qhov tseem ceeb rau cov tshuaj ntxuav khaub ncaws. Raws li ntau xyoo ntawm kev siv, DSD acid bis-triazine thiab distyryl biphenyl Optical Brighteners muab kev ua haujlwm zoo tshaj plaws.

Ntawm cov no,CI Optical Brightener 351thiabCI Optical Brightener 71yog cov variants siv dav tshaj plaws thoob ntiaj teb - tseem hu uaCov Tshuaj Ci Ntxuam Optical Brightener CBS thiab Optical Brightener CXT, ob hom tseem ceeb tau txais yuav dav hauv kev lag luam ntxuav xab npum hauv Suav teb thiab lees paub thoob ntiaj teb.

6. Cov Tshuaj Pom Zoo ntawm Cov Tshuaj Ci Ntxim Saib Hauv Cov Tshuaj Ntxuav Khaub Ncaws

Ntau dua tsis zoo duathaum nws los txog rau qhov ntau npaum li cas ntawm Optical Brighteners hauv cov tshuaj ntxuav khaub ncaws. Qhov ntau npaum li cas zoo tshaj plaws yog txiav txim siab los ntawm cov yam xws li cov qauv tshuaj ntxuav khaub ncaws, lub hom phiaj siv, thiab hom Optical brightener tshwj xeeb.

Lub teeb daj ntawm cov ntaub ntxhua khaub ncaws muaj qhov txwv, yog li qhov ntau ntawm cov teeb xiav-violet fluorescence uas xav tau los daws nws kuj muaj tsawg. Thaum qhov kev sib sau ua ke ntawm Optical Brighteners ntawm cov ntaub nce ntxiv, qhov muaj zog ntawm cov teeb xiav-violet fluorescence uas tso tawm nce ntxiv, ua rau cov ntaub dawb zuj zus.

Thaum qhov kev sib xyaw ua ke mus txog qib zoo tshaj plaws, qhov muaj zog ntawm cov teeb ci xiav-violet uas tawm los yuav ua rau lub teeb daj ntawm daim ntaub ploj mus—qhov no yog qhov taw tes ntawm qhov ua kom dawb tshaj plawsKev nce ntxiv ntawm cov tshuaj yuav ua rau cov xim dawb poob qis.

Qhov cwj pwm no qhia txog qhov tseem ceeb ntawm kev tswj hwm cov tshuaj kom raug. Hauv Tebchaws Europe thiab Tebchaws Meskas, cov tshuaj Optical Brighteners uas pom zoo hauv cov tshuaj ntxuav tes yog cov ntau yam.txij li 0.05% mus rau 0.5%.

7. Kev Nyab Xeeb ntawm Cov Tshuaj Ci Ntxuam Rau Kev Siv Xab Npum

Kev nyab xeeb ntawm Optical Brighteners yog qhov kev txhawj xeeb tseem ceeb rau cov neeg siv khoom, thiab txawm tias yog qhov ua rau muaj kev tsis ntseeg thiab kev ntxhov siab tsis tsim nyog. Rau Optical Brightener CBS thiab CXT - ob hom kev hloov pauv feem ntau siv hauv kev lag luam ntxuav khaub ncaws - cov kws tshawb fawb txog tshuaj lom thiab cov kws tshawb fawb txog ecology thoob ntiaj teb tau ua kev tshawb fawb txog kev tshawb fawb txog cov tsiaj hauv chaw kuaj mob thiab cov neeg ua haujlwm pab dawb los ntsuas lawv txoj kev nyab xeeb.

Cov kev tshawb fawb no qhia txog kev lom tshuaj heev, kev lom tshuaj ntawm daim tawv nqaij, kev khaus, kev ua rau lub siab xav, kev lom tshuaj genotoxicity, kev lom tshuaj ntau zaus, kev ua rau lub cev tsis zoo, kev ua rau mob qog nqaij hlav, kev sib sau ua ke hauv lub cev, nrog rau lawv cov kev sib sau ua ke hauv cov dej thiab av. Tsis tas li ntawd, kev sim thiab kev txiav txim siab tau ua tiav rau cov xwm txheej uas tib neeg yuav raug tshuaj, qib kev raug tshuaj, thiab cov kev txwv kev raug tshuaj.

Cov lus xaus yog meej thiab meej:

1. Cov ntaub ntawv tshiab kawg los ntawm European Chemicals Agency (ECHA) lees paub tias Optical Brighteners rau kev siv tshuaj ntxuav yogtsis yog PBT (Persistent, Bioaccumulative, Toxic) lossis vPvB (very Persistent, very Bioaccumulative) cov tshuaj.

2. Cov khoom ua kom pom kev ci ntsa iab yogtsis suav nrognyob rau hauv daim ntawv teev cov xim txwv tsis pub siv los ntawm European Union thiab International Association for Research and Testing in the Field of Textile Ecology (Oeko-Tex).

3.Pawg Sab Laj Kev Lag Luam Tshuaj European (CEFIC) thiab cov koom haum xab npum thiab tshuaj ntxuav hauv tebchaws lees paub tias Optical Brighteners rau kev siv tshuaj ntxuav yog muaj kev nyab xeeb thiabtsis ua rau muaj kev puas tsuaj rau tib neeg kev noj qab haus huv lossis ib puag ncig.

4. Lub Koom Haum Xab Npum thiab Tshuaj Ntxuav Khaub Ncaws Nyiv (JSDA) xaus lus tias cov tshuaj ua kom ci ntsa iab rau kev siv tshuaj ntxuav khaub ncaws muaj ib qhokev pheej hmoo tsawg heevrau tib neeg kev noj qab haus huv thiab ib puag ncig.

Cov lus piav qhia no muab kev nkag siab dav dav thiab raug ntawm Optical Brighteners thiab lawv daim ntawv thov hauv cov tshuaj ntxuav tes.
