CI Fluorescent Brightener PS-2000

Fluorescent Brightener PS-2000 yog ib qho zoo heev polymer-raws li optical brightener, tshwj xeeb tshaj yog engineered kom tau raws li cov kev xav tau nruj ntawm siab- kawg yas thiab fiber ntau daim ntaub ntawv uas tsis kam mus tsiv teb tsaws thiab ntev -lub sij hawm stability yog ib qho tseem ceeb. Tsis zoo li cov pa qis-molecular- hnyav brighteners, nws cov qauv tshuaj yog ua raws li tus qauv tsim, siab -molecular- hnyav polymer nraub qaum nrog nqaim molecular hnyav tis. Qhov kev tsim qauv no nthuav tawm cov khoom lag luam nrog kev txhim kho cov melting ntau thiab zoo dua thermal kuj, tso cai rau nws nyob ruaj khov nyob rau hauv kev xav tau siab -kub ua hauj lwm tej yam kev mob- xws li extrusion, txhaj molding, los yog spinning ntawm engineering plastics-tsis muaj thermal degradation los yog poob ntawm optical kev ua si.

Cov khoom yog muab los ua daj daj mus rau dawb, dawb- ntws granular daim ntawv los yog hmoov zoo, ua kom yooj yim ntawm kev tuav, meej metering, thiab sai dispersion nyob rau hauv polymer matrices. Nws qhov xwm txheej polymeric yog qhov tseem ceeb rau nws qhov tshwj xeeb kev tsiv teb tsaws chaw. Nrog rau qhov qis qis ntawm cov molecular txav piv rau cov me me - cov khoom ci ci, PS-2000 nthuav tawm tsawg kawg nkaus nyiam tsiv teb tsaws, tawg, lossis nthuav tawm mus rau saum npoo ntawm cov khoom tiav. Qhov no zoo tshem tawm qhov tshwm sim tsis zoo xws li "phaj-tawm" lossis "blooming" uas tuaj yeem tshwm sim ntawm cov khoom yas nyob rau lub sijhawm, yog li khaws cov kev zoo nkauj thiab kev ua haujlwm ntawm cov khoom thoob plaws hauv lawv lub neej.

Optically, Fluorescent Brightener PS-2000 ua haujlwm los ntawm kev ua haujlwm zoo fluorescent. Nws absorbs ultraviolet lub teeb nrog lub ncov nqus wavelength ntawm kwv yees li 365 nm thiab rov emits lub zog no li khaus xiav fluorescence (emission range 430-440 nm). Qhov no emission xiav lub teeb counteracts lub hauv paus yellowish los yog greyish tint ntawm substrates, ua rau ib tug visually whiter, ci, thiab huv si tsos. Lub brightener lub siab fluorescent tawm los ua kom muaj kev nyab xeeb thiab ci ntsa iab txawm tias qis ntxiv (feem ntau 0.02-0.2 wt%), yam tsis muaj kev cuam tshuam cov khoom siv hluav taws xob lossis thermal ntawm tus tswv tsev polymer.

Fluorescent Brightener PS-2000 yog qhov zoo tshaj plaws rau cov khoom siv hluav taws xob zoo thiab cov fibers uas xav tau kev tsiv teb tsaws zoo thiab ua haujlwm ntev. Nws cov ntawv thov tseem ceeb suav nrog:

Khoom noj khoom haus-Cov ntaub ntawv ntim khoom: Qhov twg tsis yog- cov khoom tsiv teb tsaws yog qhov tseem ceeb rau kev ua raws li cov cai tswj kev nyab xeeb khoom noj.

Automotive Sab hauv Cheebtsam: Xws li dashboards, qhov rooj vaj huam sib luag, thiab trim, uas yuav tsum muaj xim thiab zoo li nyob rau hauv lub sij hawm raug tshav kub thiab UV hluav taws xob.

High-Tsev Khoom Siv Hauv Tsev thiab Cov Khoom Siv Hluav Taws Xob Hluav Taws Xob: Qhov chaw zoo nkauj ntawm lub ntsej muag thiab lub sijhawm ntev - xim ruaj khov yog cov ntsiab lus muag muag.

High-Kev ua tau zoo Fibers thiab Technical Textiles: Yuav tsum tau ua kom zoo nkauj zoo nkauj thiab ci ntsa iab uas tiv taus kev ntxuav dua thiab raug UV.

Cov qauv polymeric ntawm PS-2000 ua kom muaj kev sib raug zoo nrog ntau cov txheej txheem polymer, suav nrog polyolefins (PP, PE), polystyrene (PS), ABS, polycarbonate (PC), thiab polyesters. Nws tsis cuam tshuam nrog lwm cov additives, xws li stabilizers, pigments, los yog fillers, thiab tuaj yeem koom ua ke ntawm kev sib xyaw qhuav, masterbatch, lossis kev sib xyaw ncaj qha. Tsis tas li ntawd, nws qhov kev ruaj ntseg nyob rau hauv lub polymer matrix guarantees tias cov nyhuv whitening tseem zoo ib yam nyob rau hauv lub sij hawm, txawm nyob rau hauv hnyav ib puag ncig tej yam kev mob-ua rau nws yog ib tug zoo tagnrho xaiv rau daim ntaub ntawv uas cov khoom nteg ntev thiab zoo li tuav yog qhov tseem ceeb.

Fluorescent Brightener PS-2000 yog tsim los ntawm kev tswj xyuas kom zoo, nrog rau txhua pawg ua haujlwm rau cov khoom hnyav molecular faib, thermal stability, thiab kho qhov muag kev ua tau zoo los xyuas kom muaj kev rov ua dua tshiab. Peb muab kev pab txhawb nqa los pab cov neeg siv khoom xaiv qhov zoo tshaj plaws noj, kev koom ua ke, thiab kev ua haujlwm tsis zoo rau lawv cov resin tshwj xeeb thiab daim ntawv thov xav tau.

1. Txoj Kev Dyeing Exhaustion

Formula: Ntxiv fluorescent whitening tus neeg saib xyuas PS-2000H3 ntawm 0.15% ~ 0.4% (owf) ntawm cov ntaub hnyav, thiab kho cov pH ntawm cov dye da dej rau qhov ntau ntawm 5 ~ 6 nrog acetic acid.

Cov cawv sib piv: Tswj ntawm 1: 10 thiab 1: 30, uas tuaj yeem hloov kho tau yooj yim raws li cov khoom siv thiab hom ntaub.

Cov txheej txheem txheej txheem: Dye tsis tu ncua ntawm qhov kub ntawm 100 ~ 135℃rau 30 ~ 60 feeb.

Tswv yim: Hauv kev tsim khoom tiag tiag, nws raug nquahu kom txiav txim siab cov txheej txheem tsim nyog tshaj plaws los ntawm kev siv me me - teev dyeing kom ua tiav cov txiaj ntsig zoo tshaj plaws.

2. Pad-Dyeing Kub- Txoj Kev Melt

Formula: Thaum npaj cov tshuaj ua haujlwm, ntxiv fluorescent whitening agent PS-2000H3 ntawm qhov concentration ntawm 1.5 ~ 4g / L.

Cov txheej txheem txheej txheem: Ua ob lub dips thiab ob lub ncoo ntawm cov ntaub, tswj cov padding tus nqi mus txog kwv yees li 70%.

Cov ntaub ces nkag mus rau theem ua ntej- ziab, qhov twg nws pib qhuav ntawm 100℃.

Thaum kawg, nws dhau qhov kub ntawm 180 ~ 200℃rau 20 ~ 30 vib nas this.

Kev ceeb toom tseem ceeb: Tom qab cov txheej txheem pretreatment, cov ntaub yuav tsum tau ntxuav kom huv si kom tsis txhob muaj cov alkali seem uas cuam tshuam rau cov nyhuv whitening tom ntej.
