Hlau oxide xim yog ib hom xim muaj nrog kev faib tawm zoo, zoo heev lub teeb tsis kam thiab huab cua tsis kam. Cov hlau oxide pigments tsuas yog hais txog plaub hom xim xim, hlau oxide liab, hlau daj, hlau dub thiab hlau xim av, raws li hlau oxide, ntawm cov hlau oxide liab yog lub ntsiab lus tseem ceeb (kwv yees li 50% ntawm cov hlau oxide pigments), Mica hlau oxide siv los tiv thaiv xeb xim thiab siv hlau oxide siv los ua cov ntaub ntawv sau tseg cov hlau nplaum kuj yog rau cov qeb ntawm cov hlau oxide pigments. Cov hlau oxide yog qhov thib ob loj tshaj plaws hauv cov xim inorganic tom qab titanium dioxide thiab cov xim loj tshaj plaws inorganic xim. Ntawm tag nrho cov hlau oxide pigments noj, ntau dua 70% yog npaj los ntawm cov tshuaj lom neeg, uas yog hu ua hluavtaws hlau oxide.
Cov hlau oxide pigments thiab cov ntsaws muaj cov xim liab, daj, dub, txiv kab ntxwv, thiab lwm yam Ntawm lawv, cov xim liab thiab daj hlau oxide xim tau siv ntau tshaj plaws hauv thaj teb ntawm txheej txheej txheej txheej txheej, thiab cov hlau oxide pigments muaj kev cuam tshuam los ntawm ntau yam rog hauv cov txheej txheem npaj cov txheej txaij architectural. Agglomeration yuav cuam tshuam rau cov xim zog, zais lub zog, ci, thiab lwm yam ntawm cov xim thaum lub txheej txheem txheej. Yog li ntawd, nws yog qhov tsim nyog yuav tsum tau nruab nrog kev ua haujlwm siab-siab ua kom haum rau hlau oxide liab thiab daj xim.
Cov hlau oxide liab thiab daj xim dispersants yuav tsum muaj peev xwm txhim kho cov ua haujlwm ntawm cov xim txig los ntawm peb qho:
1. Nws tuaj yeem ua kom cov xim txhim kho cov xim ntxiv thiab ua kom yooj yim sib tsoo.
2. Cov khoom siv hluav taws xob no tuaj yeem siv kom tawg txhua hom hlau oxide, thiaj li txo tau cov hom dispersants uas yuav tsum tau. Qhov no yog qhov sib txawv tshwj xeeb tshaj plaws ntawm nws thiab polyacrylate additives.
3. Lub tshuab hluav taws xob nqaim cov nqi thiab kev ua haujlwm sib txawv nrog ntau cov khoom sib ntxiv kim polymer.
Lub hauv paus ntsiab lus ntawm hlau oxide dispersant yog tias cov khoom tshiab ua kom muaj qhov zoo ntawm ob sab ntawm electrostatic kev ruaj ntseg thiab steric stability. Txawm hais tias nws xav tau khaws cia rau lub sijhawm ntev, nws tseem tuaj yeem muab cov xim txhim kho kom ntev thiab ua kom muaj kev sib txuam ntawm lub zog siab. Tsis tas li ntawd, cov roj ntsha ntxiv tuaj yeem txo qhov viscosity ntawm cov xim xim kom pom tseeb, kom cov xim ntau dua tuaj yeem muab ntxiv rau qhov mloog kom txo qis cov xim xav tau kom npog thaj tsam thaj chaw.
Txheeb suav, qhov kev thov rau lub zog zais thiab xim muaj zog ntawm cov xim tsev thiab cov ntawv sau rau hauv cov vaj tsev tsim ua vaj tse ntau zuj zus tuaj, uas ua kom muaj ntau qhov xav tau ntawm kev siv cov hlau oxide dispersants, thiab xav tau cov hlau oxide hmoov ua los ntawm cov xim sib txawv thiab cov txheej txheem Cov.
