Nrog rau kev nce qib ntawm cov dej tsis tu ncua -cov coatings, eco- cov phooj ywg coatings, thiab cov txheej txheem kev lag luam, kev tsim cov yeeb yaj kiab- kev pab cuam yog hloov los ntawm ib qho kev tsom mus rau zaj duab xis - ua kev ua tau zoo mus rau eco- kev phooj ywg, kev ua haujlwm siab, ntau yam tshwj xeeb. Thaum cov yeeb yaj kiab ib txwm siv- kev tsim cov khoom siv feem ntau hais txog qhov kev sib tw ntawm qis- qhov kub thiab txias ntawm cov yeeb yaj kiab tsim hauv emulsions, cov kev xav tau niaj hnub xav kom muaj qhov sib npaug ntawm cov cwj pwm kev ua tau zoo-xws li VOC emissions, tsw, zaj duab xis hardness, dej tsis kam, thiab cia ruaj khov- nrog rau kev tsim cov yeeb yaj kiab zoo. Yog li ntawd, yav tom ntej zaj duab xis- kev pab tsim yuav tsum txo qis lawv qhov cuam tshuam rau ib puag ncig thiab tib neeg kev noj qab haus huv thaum tuav cov yeeb yaj kiab zoo heev - tsim muaj peev xwm.
Eco-tus phooj ywg thiab qis-VOC zaj duab xis- tsim cov kev pabcuam sawv cev rau txoj kev loj hlob tseem ceeb. Raws li daim ntawv thov dav dav ntawm dej- cov coatings ua rau nthuav dav, kev ua lag luam xav tau cov khoom lag luam uas tsis muaj ntxhiab tsw thiab tsis muaj volatile organic compound (VOC) cov ntsiab lus. Cov kev txhim kho yav tom ntej yuav ua qhov tseem ceeb txo qis qis thiab qhov seem seem thaum txhim kho zaj duab xis- ua kom muaj txiaj ntsig ntawm ib chav tsev ntawm qhov ntau npaum li cas, yog li ua tiav cov yeeb yaj kiab zoo tshaj plaws nrog cov khoom siv me me. Tsis tas li ntawd, cov khoom siv raw uas muaj kev cuam tshuam ib puag ncig qis, biodegradability zoo dua, lossis ntau dua cov hauv paus ntsiab lus yuav ua rau muaj kev xav ntau dua. Rau cov hlau txheej emulsions, txo VOC cov ntsiab lus thaum ntsib zaj duab xis- tsim cov kev xav tau pab tsav cov evolution ntawm dej{10}}cov txheej hlau ua rau muaj kev ruaj ntseg ntau dua.
Lwm qhov sib txawv loj yog txav mus rau kev ua haujlwm siab thiab kev ua haujlwm ntau. Yav tom ntej zaj duab xis- kev pab tsim yuav tsum tsis tsuas yog txo qhov tsawg kawg nkaus zaj duab xis- ua qhov kub thiab txias, tab sis kuj sib npaug zog xws li zaj duab xis hardness, yooj, adhesion, dej tsis kam, abrasion resistance, thiab corrosion kuj. Los ntawm kev tsim qauv molecular thiab cov thev naus laus zis sib xyaw, zaj duab xis- cov khoom siv tuaj yeem tsim kho kom muaj ntau txoj haujlwm, yog li txo qhov ntau thiab ntau ntawm cov khoom ntxiv uas xav tau hauv kev tsim. Piv txwv li, zaj duab xis- tsim cov khoom siv rau cov hlau substrates tuaj yeem tsim los txhawb cov coalescence ntawm emulsion hais thaum txhawb kev tsim cov yeeb yaj kiab denser, thaum kawg txhim kho cov txheej tiv thaiv kev ua haujlwm ntawm cov hlau.
Kev tshwj xeeb thiab kev sib xyaw thev naus laus zis tseem yuav ua lub luag haujlwm tseem ceeb rau yav tom ntej. Cov tshuab sib txawv ntawm emulsion-xws li acrylic emulsions, styrene-acrylic emulsions, thiab lwm yam dej-cov khoom siv hluav taws xob- muaj cov kev cai sib txawv ntawm cov yeeb yaj kiab- ua kom sov thiab sib haum. Yog li ntawd, cov khoom lag luam yav tom ntej yuav nce siab ntxiv rau cov qauv tsim kom haum rau cov resins tshwj xeeb thiab daim ntawv thov scenarios-xws li kev tsim cov yeeb yaj kiab tshwj xeeb- tsim cov khoom siv ntxiv rau dej-raws li cov txheej hlau, ntoo tiav, cov txheej txheem vaj tsev, thiab cov txheej txheem tiv thaiv kev lag luam. Tsis tas li ntawd, los ntawm kev sib txuas ntau hom yeeb yaj kiab- tsim cov khoom siv ntxiv, nws tuaj yeem hloov kho tus nqi evaporation thiab cov yeeb yaj kiab- txheej txheem tsim; qhov no tso cai rau kev tsim cov yeeb yaj kiab zoo ntawm qhov kub thiab txias thaum tib lub sijhawm txhim kho cov txheej txheem kawg hardness thiab dej tsis kam.
