Optical Brightener Agent: Puas Yog Lawv Dyes lossis Pab Koom Tes?

Dab tsi yog Optical Brightener Agent?

British physicist George Gabriel Stokes thawj zaug piav txog qhov tshwm sim ntawm fluorescence nyob rau hauv 1852. Nyob rau hauv 1929, Krais.P thawj pom tias 6,7-dihydroxycoumarin muaj fluorescent whitening nyhuv;Xyoo 1940, lub tuam txhab German IG tau tsim cov tshuaj tua kab mob fluorescent nrog tus nqi tsim nyog thiab pib nws txoj kev lag luam.

Xyoo 1959, thawj lub Hoobkas Tianjin dye Hoobkas tsim Tuam Tshoj tus thawj Optical Brightener tus neeg sawv cev, VBL (CI85), uas yog ib hom bistriazine aminostilbene.Xyoo 1966, yav dhau los Ministry of Chemical Industry tau tshaj tawm cov qauv kev lag luam tshuaj rau ntau yam no (Tsoomfwv-tsim qauv), suav nrog HG 2-382-66, uas yog thawj qhov kev lag luam tus qauv rau cov khoom siv kho qhov muag hauv Suav teb.Cov qauv khoom tam sim no tau hloov kho mus rau GB / T 10661-2003 'Fluorescent Whitening Agent VBL'.Fluorescent brighteners yog Ameslikas tsuas yog siv hauv textile printing thiab dyeing kev lag luam hauv Suav teb.Thaum xyoo 1960s, cov neeg ua haujlwm kho qhov muag tau pib siv rau hauv kev lag luam tshuaj tua hluav taws, thiab tsuas yog siv hauv kev lag luam ntawv hauv xyoo 1970s.

Optical Brightener Agent yog siv rau ntau yam kev siv, los ntawm textiles mus rau detergents, plastics, coatings, inks, thiab tawv.Nrog rau kev txhim kho kev lag luam sai, kev siv thiab ntau npaum li cas ntawm cov tshuaj fluorescent whitening tseem tab tom nthuav dav.Tam sim no, kev lag luam textile tsis yog thaj chaw uas muaj ntau tshaj plaws ntawm Optical brightener tus neeg sawv cev.Nyob rau hauv ntau lub teb chaws nyob rau hauv lub ntiaj teb no, muaj qhov sib txawv ntawm qhov kev faib ua feem ntawm Optical brightener tus neeg sawv cev nyob rau hauv txawv industries, tab sis qhov kev txiav txim ntawm kev faib ua feem ntawm kev siv yog yeej ib txwm zoo ib yam: uas yog, nws yog tsuas yog siv nyob rau hauv detergents, ua raws li los ntawm papermaking, textiles, thiab plastics thiab lwm qhov chaw hauv cov khoom me me.

Daim ntawv thov hauv Textile Field

optical brightener tus neeg sawv cev tau siv hauv kev lag luam textile rau ze li ntawm 70 xyoo.Lawv tau txais kev pom zoo los ntawm dyeing thiab xov kev lag luam thiab cov neeg siv khoom vim lawv qhov tshwj xeeb whitening thiab brightening los ntawm textile fibers.Tam sim no, tsis muaj kev siv thev naus laus zis uas tuaj yeem hloov lub luag haujlwm ntawm cov neeg ua haujlwm kho qhov muag brightener.

Qee cov neeg xav tias cov tshuaj dawb tuaj yeem hloov kho qhov muag pom qhov muag pom kev.Thiab qee cov khoom lag luam hauv cheeb tsam no tau tshawb fawb, xws li tshuaj chlorine bleaching thiab oxygen bleaching kom ua tiav cov xim dawb ntawm cov ntaub.

Muaj qhov yuav tsum tau ua rau daim ntawv thov ntawm tus neeg saib xyuas qhov muag pom ntawm textiles, uas yuav tsum ua kom tau raws li 5 yam hauv qab no:

① Tsis muaj kev puas tsuaj rau cov fiber ntau, thiab nws muaj cov pob zoo thiab lub zog;

② muaj dej solubility zoo dua;

③ Muaj tshuaj lom neeg ruaj khov;

④ Muaj kev ua kom zoo dua qub;

⑤ Tsis muaj teeb meem rau ib puag ncig.

Raws li hom tshuaj qauv, tus neeg saib xyuas qhov muag pom kev siv hauv kev lag luam textile feem ntau suav nrog rau 6 pawg:

① Ditriazine amino stilbene hom;

② stilbene biphenyl yam;

③ hom bisbenzoxazole;

④ stilbene benzene hom;

⑤ Pyrazoline hom;

⑥ Coumarin hom.

Thaum siv tus neeg sawv cev kho qhov muag pom kev zoo, tus neeg sawv cev tsim kho qhov muag yuav tsum raug xaiv raws li cov tshuaj muaj pes tsawg leeg thiab cov khoom siv lub cev ntawm fiber ntau, thiaj li kom tau txais txiaj ntsig zoo nkauj.

Thoob ntiaj teb, optical brightener agents raug suav hais tias yog cov xim dawb, thiab txhua tus qauv kho qhov muag brightener tus neeg saib xyuas muaj nws tus lej dye index;nyob rau hauv Suav teb, optical brightener agents feem ntau suav hais tias yog ib qho tseem ceeb functionality Finishing pab.

optical brightener tus neeg sawv cev yog siv los ua dyes, thiab lawv txoj kev nyab xeeb yuav tsum ua tau raws li cov qauv kev nyab xeeb rau dyes.Tuam Tshoj tau tshaj tawm ob tus qauv:

GB 19601-2013 'Txoj kev txwv thiab kev txiav txim siab ntawm 23 teeb meem muaj ntxhiab amines hauv cov khoom dye'

GB 20814-2014 'Kev txwv thiab kev txiav txim siab ntawm 10 cov hlau hnyav hauv cov khoom siv zas'

Kev soj ntsuam ntawm 23 teeb meem amines nyob rau hauv cov khoom dye los ntawm roj chromatography / huab hwm coj spectrometry thiab lwm yam analytical txoj kev muab ib tug txhim khu kev qha lub hauv paus rau kev tshawb nrhiav cov teeb meem aromatic amine tebchaw nyob rau hauv cov khoom dye, thiab ntxiv txwv tsis pub cov ntsiab lus ntawm teeb meem aromatic amines nyob rau hauv cov khoom dye ( ≤ 150mg / kg);Kev txiav txim siab ntawm cov hlau hnyav hauv cov khoom siv dyeing los ntawm atomic absorption spectrometry muab lub hauv paus txhim khu kev qha rau kev tshawb pom cov hlau hnyav hauv cov khoom dye, yog li txwv cov ntsiab lus ntawm cov hlau hnyav hauv cov khoom dye.

optical brightener tus neeg saib xyuas yog siv los ua cov pab cuam, thiab lawv txoj kev nyab xeeb yuav tsum ua tau raws li cov qauv kev nyab xeeb ntawm cov koom haum pab.Xyoo 2006, General Administration of Quality Supervision, Inspection and Quarantine and the National Standardization Administration of the People's Republic of China tau tshaj tawm GB / T 20708-2006 'Txoj kev txwv thiab txiav txim siab ntawm qee yam teeb meem hauv Textile Auxiliary Products'.Aromatic amines (≤ 30mg / kg, nruj dua cov qauv dye), txwv tsis pub cov hlau hnyav thiab formaldehyde, cov kev sim, cov cai tshuaj xyuas, cov ntaub ntawv xeem.

Daim ntawv thov ntawm optical brightener tus neeg sawv cev hauv kev lag luam textile thiab kev nyab xeeb ntawm textiles uas tau dhau los ua ntau yam hauv kev ua lag luam kuj tau lees paub los ntawm qhov yuav tsum tau muaj kev ruaj ntseg technical specifications.Tuam Tshoj tam sim no GB 18401-2010 'National Basic Safety Technical Specifications for Textile Products', tus qauv qhia cov txheej txheem kev nyab xeeb yooj yim, cov qauv kev sim, kev soj ntsuam cov cai thiab kev siv cov khoom me nyuam mos thiab me nyuam me, cov khoom ncaj qha rau ntawm daim tawv nqaij, thiab cov khoom siv. tsis nyob rau hauv kev sib cuag nrog daim tawv nqaij.Kev saib xyuas, suav nrog cov cai txwv rau kev txwv tsis pub decomposable aromatic amine dyes, formaldehyde txwv, pH, thiab lwm yam.

Yog li ntawd, tsis hais seb tus neeg saib xyuas qhov muag pom qhov muag puas yog siv los ua cov xim pleev xim lossis ua ib qho kev pabcuam, tsuav yog lub tuam txhab tsim cov khoom siv kho qhov muag brightener tus neeg sawv cev tuaj yeem tsim, muag, thiab siv tus neeg saib xyuas qhov muag pom qhov muag uas ua tau raws li cov qauv, kev siv. ntawm optical brightener tus neeg sawv cev cov khoom ntawm textiles yuav tau txais kev nyab xeeb.Nws tsis yog qhov nyuaj rau kev nkag siab tias nws tseem muaj kev nyab xeeb ntxiv rau tus neeg sawv cev kho qhov muag brightener rau cov tshuaj ntxuav khaub ncaws thiab lwm yam ntaub.

Txawm li cas los xij, nrog rau txoj kev loj hlob ntawm Tuam Tshoj txoj kev lag luam thiab kev txhim kho ntawm kev ua neej nyob, qhov kev thov rau cov neeg ua haujlwm kho qhov muag brightener tseem yuav ua kom nrawm nrog lub hnub, thiab kev txhim kho ntawm cov neeg ua haujlwm kho qhov muag brightener kuj yuav nrawm.Nws yog ib qho tsim nyog yuav tsum ua raws li kev txhim kho thev naus laus zis thiab hloov kho cov qauv, ntxiv dag zog rau kev tshawb fawb txog kev nyab xeeb ntawm ntau yam tshiab, thiab tswj kev ua lag luam.Tsis hais txog ntawm kev lag luam uas tus neeg sawv cev kho qhov muag ci ntsa iab, yuav tsum muaj kev tshawb fawb txog kev nyab xeeb thiab cov qauv siv, kom peb cov neeg siv khoom noj qab haus huv tuaj yeem lav tau, thiab ntau qhov chaw ntawm kev lag luam hauv tebchaws tuaj yeem txhim kho kev noj qab haus huv. thiab ua kom zoo.
