Niaj hnub no, raws li kev lag luam ntawm cov ntaub ntawv tshawb fawb txuas ntxiv txhim kho, kev nrhiav kev ua tau zoo ntawm cov khoom tseem zoo li qub. Dispersible titanium dioxide yog ib qho ntawm unsung heroes ntawm txoj kev loj hlob no, tshwj xeeb tshaj yog nyob rau hauv lub teb ntawm cov txiv neej ua fibers. Cov khoom lag luam tshwj xeeb no tau tsim los siv cov thev naus laus zis North American ntau lawm tau dhau los ua cov khoom lag luam hloov pauv rau cov tuam txhab tshuaj fiber ntau hauv tsev.
Lub hauv paus ntawm qhov kev tsim kho tshiab no yog Kewei, uas tau dhau los ua tus thawj coj hauv kev tsim cov titanium dioxide raws li cov txheej txheem sulfuric acid. Kewei tau cog lus rau kev ua tau zoo, kev tiv thaiv ib puag ncig thiab kev siv thev naus laus zis, siv cov khoom tshwj xeeb ntawm titanium dioxide los txhim kho kev ua haujlwm ntawm cov tshuaj fibers.
Yog li cas lub luag haujlwm uadispersion titanium dioxideua si hauv kev txhim kho cov khoom lag luam? Cov lus teb nyob hauv nws cov khoom tshwj xeeb. Titanium dioxide paub txog nws qhov siab refractive index, zoo heev UV tsis kam, thiab zoo heev opacity. Thaum ntxiv rau cov tshuaj fibers, nws tuaj yeem ua rau kom muaj zog thiab ua haujlwm ntev ntawm cov khoom kawg. Qhov no yog qhov tseem ceeb tshwj xeeb hauv cov ntawv thov uas raug tshav ntuj thiab ib puag ncig tej yam yuav ua rau cov khoom degrade dhau sijhawm.
Tsis tas li ntawd, kev siv dispersedtitanium dioxidenyob rau hauv tshuaj fibers pab txhim kho xim stability. Daim ntawv anatase ntawm titanium dioxide yog tshwj xeeb tshaj yog zoo ntawm kev tswj cov xim vibrancy, kom ntseeg tau tias cov khoom khaws lawv cov kev zoo nkauj txawm tias tom qab siv ntev. Qhov no yog qhov tseem ceeb tshaj plaws rau cov tuam txhab lag luam txhawm rau ua kom tau raws li cov neeg siv khoom xav tau rau cov khoom lag luam zoo, pom kev pom zoo.
Ntxiv nrog rau kev zoo nkauj, dispersed titanium dioxide kuj ua lub luag haujlwm tseem ceeb hauv kev ua haujlwm ntawm cov tshuaj fibers. Nws zoo diffuses lub teeb, yog li txhim kho cov thermal zog ntawm cov fiber ntau, ua rau nws xis nyob rau hauv ntau yam kev nyab xeeb. Qhov no tshwj xeeb tshaj yog muaj txiaj ntsig zoo hauv kev lag luam textile, qhov kev nplij siab thiab kev ua haujlwm yog qhov tseem ceeb tshaj plaws.
Kewei tau cog lus tias yuav siv cov cuab yeej siv ntau tshaj plaws los xyuas kom meej tias cov titanium dioxide uas ua tau zoo tshaj plaws. Lub tuam txhab cov txheej txheem kev siv tshuab ua kom muaj kev tswj xyuas meej ntawm titanium dioxide particle loj thiab kev faib tawm, uas yog ib qho tseem ceeb rau kev ua tiav kev pom kev tawg ntawm cov tshuaj fibers. Qhov kev tswj hwm qib no tsis tsuas yog txhim kho fiber ntau kev ua tau zoo tab sis kuj tseem txhawb nqa tag nrho kev ruaj ntseg ntawm cov txheej txheem tsim khoom.
Tsis tas li ntawd, Coolway txoj kev cog lus rau kev tiv thaiv ib puag ncig ua ke nrog qhov kev thov loj hlob rau kev coj ua kom ruaj khov hauv kev tsim khoom lag luam. Los ntawm kev tsim cov khoom zoo sulfate-txheej txheem titanium dioxide, lub tuam txhab txo cov pov tseg thiab txo cov kev cuam tshuam ib puag ncig ntawm cov txheej txheem ntau lawm. Tsis tsuas yog qhov no zoo rau lub ntiaj teb, nws kuj ua rau Coolway ua tus thawj coj hauv kev lag luam.
Nyob rau hauv luv luv, lub luag hauj lwm ntawm dispersed titanium dioxide nyob rau hauv kev txhim kho cov khoom ua tau zoo yuav tsis tau underestimated. Raws li cov khoom lag luam tshwj xeeb anatase, nws muaj cov khoom siv hluavtaws fiber ntau ntau cov txiaj ntsig, los ntawm kev txhim kho durability thiab xim stability kom txhim kho thermal zog. Nrog cov thawj coj hauv kev lag luam zoo li Kewei ntawm qhov ua ntej ntawm kev tsim kho tshiab, yav tom ntej ntawm cov tshuaj fibers zoo li ci ntsa iab. Raws li cov chaw tsim khoom txuas ntxiv mus nrhiav txoj hauv kev los txhim kho cov khoom zoo, kev sib koom ua ke ntawm cov titanium dioxide dispersed yuav tsis muaj qhov tsis txaus ntseeg ua lub luag haujlwm tseem ceeb hauv kev tsim cov khoom siv ua haujlwm siab tom ntej.
