Hauv cov ntsiab lus, tus nqi tseem ceeb ntawm fluorescent whitening agents (FWAs) hauv cov xim thiab cov xim yog nyob rau hauv peb qhov tseem ceeb:
Txhim khu kev dawb huv thiab ci ntsa iab, ua kom pom cov khoom zoo, thiab txhim kho qhov kawg -siv kev ua tau zoo.
Nrog kev txhim kho txuas ntxiv ntawm cov neeg siv khoom xav tau thiab kev nce qib txuas ntxiv hauv cov txheej txheem thev naus laus zis, cov xim tau ntev dhau los ua lawv lub luag haujlwm tseem ceeb ntawm kev tiv thaiv saum npoo yooj yim. Niaj hnub no, lawv ua lub luag haujlwm tseem ceeb hauv kev ua kom zoo nkauj ntawm cov substrates thiab ua kom pom kev pom zoo. Txawm li cas los xij, feem ntau cov xim ntshiab los yog xim dawb muaj nyob rau hauv muaj cov xim daj daj thaum tsim khoom. Hauv cov txheej txheem ib txwm muaj, txhawm rau npog qhov tsis xws luag, ib txoj hauv kev "bluing" lub cev feem ntau yog ua haujlwm - ntxiv cov xim xiav los ua kom lub teeb daj raws li cov ntsiab lus xim ntxiv. Tab sis txoj hauv kev no feem ntau ua rau dull, greyish dawb zaj duab xis uas tsis muaj qhov ci thiab vibrancy.
Piv txwv li,fluorescent whitening agents, raws li cov khoom siv kho qhov muag, tuaj yeem nqus tsis pom lub teeb ultraviolet thiab rov- tawm nws li xiav -violet fluorescence. Qhov xiav no -violet lub teeb optically ntxiv rau lub teeb daj uas tshwm sim los ntawm txheej txheej, ua kom muaj qhov zoo tagnrho tag nrho - reflection dawb lub teeb nyhuv. Los ntawm qhov pom kev pom, cov xim dawb tshwmhuv si, ci dua, thiab ntau luminous, thaum lub teeb - cov xim coatings saibntau vivid thiab qhov muag -catching. Lub zuag qhia tag nrho aesthetic zoo ntawm cov khoom ua tiav ib tug zoo leap.
Tsis tas li ntawd, FWAs tuaj yeem nqus tau zoo lossis thaiv ib feem ntawm cov hluav taws xob ultraviolet, txo nws txoj kev degradation ntawm cov xim thiab cov txheej txheem hauv cov txheej txheem. Qhov no txhim kho covlightfastness thiab weatherabilityntawm zaj duab xis, ho txuas ntxiv lub neej kev pab cuam ntawm cov xim raug rau sab nraum zoov thiab ncaj qha tshav ntuj tej yam kev mob. Qhov no tsis yog tsuas yog kev hloov kho zoo li tab sis kuj yog qhov pom taukev tiv thaiv.
2. Pom zoo hom thiab qib ntawm Fluorescent Whitening Agents rau xim & txheej
Cov txheej txheem txheej txheej sib txawv tsim cov kev cai sib txawv ntawm FWAs hais txog kev solubility, ionic xwm, thiab compatibility. Raws li peb lub xyoo dhau los ntawm kev pabcuam kev pabcuam hauv kev lag luam coatings, Jinan Tonex Chemical tau sau tseg cov khoom siv feem ntau hauv qab no rau cov qauv siv siv:
| Txheej Txheej Txheej | FWA Property Requirements | Cov qhab nia pom zoo (CI Number) |
|---|---|---|
| Tsis yog- dej- cov xim tsis zoo(roj-cov xim pleev xim, hnyav-cov txheej txheej, UV tshuab) | Tsis yog-ionic, dej-insoluble, dispersible yam; xav tau kev sib raug zoo nrog cov kuab tshuaj organic thiab cov txheej txheem resin | C.I. 184, C.I. 185, C.I. 199, C.I. 368, C.I. 378 |
| Dej- raws li txheej txheej(Cov xim pleev xim hauv tsev, architectural tha xim sab hauv / sab nrauv phab ntsa, cov xim muaj dej) | Anionic, dej -soluble; yuav tsum muaj zog compatibility nrog aqueous systems | C.I. 85, C.I. 220 |
Ib Daim Ntawv Pom Zoo los ntawm Jinan Tonex Tshuaj:
Cov qib uas tau teev tseg saum toj no yog txhua yam zoo- tsim, cov khoom lag luam loj tau siv dav hauv khw. Txawm li cas los xij, qhov kev xaiv zaum kawg yuav tsum yog raws li kev ntsuam xyuas dav dav ntawm koj cov qauv tsim tshwj xeeb -xws li hom resin, hnyav system, pigment muaj pes tsawg leeg, thiab lub hom phiaj whiteness.
Yog tias koj xav tau cov qauv kuaj lossis cov lus qhia ua kom zoo tshaj plaws, thov tsis txhob yig tiv tauj peb. Peb yeej ib txwm npaj los muab rau kojib qho - ntawm - ib qho kev txhawb nqa kev tshaj lij.
