Zaj duab xis-cov khoom siv feem ntau yog siv hauv cov txheej txheem txheej txheej raws li cov khoom siv polymer emulsions lossis dej-cov khoom siv, tshwj xeeb tshaj yog rau cov khoom uas xav tau cov qauv tshwj xeeb rau kev tsim cov yeeb yaj kiab, qis - daim ntawv thov kev ua haujlwm kub, thiab kev ncaj ncees ntawm zaj duab xis. Thaum lub sij hawm ziab, lawv pab txhawb cov coalescence ntawm polymer hais, ua kom lub txheej los ua ib tug nruam, uniform zaj duab xis. Yog li ntawd, lawv tau siv dav hauv cov xim latex, dej-yuav ua rau muaj txheej txheej, dej-yug ntoo coatings, thiab ntau yam dej ua haujlwm- cov coatings.
Zaj duab xis- kev pab tsim yog tsim rau cov dej- cov xim hlau tiv thaiv, txheej rau cov tshuab thiab steel qauv, hlau tivthaiv txheej, thiab lwm yam khoom siv kho mob hlau. Hlau txheej xav tau qib siab ntawm adhesion, dej tsis kam, thiab corrosion kuj; Kev tsim cov yeeb yaj kiab tsis txaus tuaj yeem ua rau muaj qhov tsis xws li micropores thiab tawg, yog li cuam tshuam kev tiv thaiv ntawm cov hlau substrate. Incorporating the appropriate amount of film-forming aid improves particle coalescence, resulting in a denser, smoother film that enhances adhesion, water resistance, and corrosion resistance.
Zaj duab xis-cov khoom siv yog siv los txhim kho daim ntawv thov thiab zaj duab xis- tsim cov yam ntxwv ntawm cov khoom xws li latex xim thiab tha xim sab hauv / sab nrauv phab ntsa. Qee cov emulsions tawm tsam tsim cov yeeb yaj kiab zoo hauv qhov chaw qis - kub; Ntxiv cov yeeb yaj kiab uas tsim nyog- kev pab tsim kom txo qis qhov tsawg kawg nkaus zaj duab xis- ua qhov kub thiab txias (MFT), tso cai rau cov txheej txheem los ua cov yeeb yaj kiab tsis zoo txawm tias nyob hauv qhov txias dua. Tsis tas li ntawd, cov kev pab no txhim kho zaj duab xis theem, gloss, thiab yooj thaum txo cov teeb meem xws li nto roughness, whitening, thiab cracking.
Zaj duab xis- kev pab tsim kuj pom daim ntawv thov hauv dej-yug ntoo coatings, tawv tiav cov neeg ua hauj lwm, textile coatings, dej-yug nplaum, thiab tej yam yas deg coatings. Nyob rau hauv cov khoom no, lawv ua hauj lwm los txhawb polymer particle coalescence, txhim khu cov zaj duab xis txuas ntxiv, thiab txhim kho daim ntawv thov versatility. Txawm li cas los xij, raws li cov emulsion resins sib txawv muaj cov kev xav tau sib txawv, qhov kev xaiv ntawm zaj duab xis- tsim kev pab hauv kev siv tswv yim yuav tsum yog raws li yam xws li hom resin, iav hloov kub, zaj duab xis yam tsawg kawg nkaus - ua kom sov, thiab qhov xav tau zaj duab xis zaum kawg.
Thaum cov yeeb yaj kiab- cov kev pabcuam tsim muaj ntau qhov kev thov, tsis yog txhua qhov dej-cov emulsions yuav tsum muaj tib hom kev pab. Thaum xaiv qhov ua tau zoo, ib qho yuav tsum xav txog kev sib raug zoo, ntau npaum li cas, evaporation tus nqi, VOC cov ntsiab lus, thiab dej tsis kam, nrog rau kev cuam tshuam ntawm txheej txheej zaj duab xis hardness thiab adhesion. Rau cov emulsions siv hauv cov hlau txheej, tshwj xeeb yog them nyiaj rau kev sib xyaw ua ke ntawm cov yeeb yaj kiab- tsim cov kev pab cuam ntawm zaj duab xis compactness, dej tsis kam, thiab corrosion kuj.
