Zaj duab xis- pab tsim cov kev pab cuam feem ntau pab txhawb kev tsim cov yeeb yaj kiab hauv emulsion txheej. Tom qab daim ntawv thov, raws li dej evaporates, cov resin hais dispersed nyob rau hauv lub emulsion los ze zog thiab sib cuag nrog ib leeg. Yog hais tias qhov kub ntawm qhov chaw nyob qis qis, cov khoom siv resin tuaj yeem ua tsis tiav thiab coalesce txaus, uas ua rau kom dawb, roughness, los yog tawg ntawm cov zaj duab xis txheej. Kev sib xyaw ua ke ntawm cov yeeb yaj kiab uas tsim nyog- kev pab tsim ua kom qis dua cov yeeb yaj kiab polymer yam tsawg kawg nkaus - ua qhov kub thiab txias, ua kom yooj yim rau cov khoom ua kom deform thiab coalesce, yog li tsim kom muaj cov yeeb yaj kiab tsis tu ncua. Qhov no yog qhov tseem ceeb tshwj xeeb tshaj yog rau cov hlau txheej emulsions, vim tias cov yeeb yaj kiab tsis zoo muab kev tiv thaiv zoo tshaj plaws ntawm cov hlau nto, tso lub hauv paus rau kev tiv thaiv ntev -.
Zaj duab xis- pab tsim kuj txhim khu kev ua tau zoo tag nrho ntawm cov zaj duab xis txheej. Thaum lub sij hawm ua zaj duab xis - txheej txheem tsim, lawv txhawb cov coalescence ntawm emulsion hais, ua rau ib tug denser thiab smoother txheej, uas txhim kho cov khoom xws li leveling, gloss, yooj, thiab nto zoo. Cov yeeb yaj kiab tsim nyog- kev pab tsim ua kom txo qis cov voids microscopic thiab qhov tsis xws luag hauv zaj duab xis, ua kom muaj kev sib cuag zoo dua thiab adhesion ntawm cov txheej thiab cov hlau substrate. Tsis tas li ntawd, kev tsim cov yeeb yaj kiab zoo tshaj plaws ua rau muaj kev txhim kho dej tsis kam, tiv thaiv corrosion, thiab weatherability, muab hlau nto nrog kev tiv thaiv ruaj khov. Txij li ntau hom emulsions thiab resins muaj ntau yam yuav tsum tau ua rau zaj duab xis - kev pab tsim, cov kev xaiv tshwj xeeb yog nyob ntawm yam xws li hom resin, daim ntawv thov kub, thiab kev ua tau zoo.
Zaj duab xis- pab tsim kuj txhim kho cov yam ntxwv ntawm daim ntawv thov, ua kom cov emulsion ntws thiab kis tau zoo thaum cov txheej txheem xws li txhuam los yog txau. Kev noj tshuaj yuav tsum tau ua tib zoo tswj; Kev sib ntxiv tsis txaus tuaj yeem ua tsis tau zoo los txhawb kev tsim cov yeeb yaj kiab, thaum sib ntxiv ntau dhau tuaj yeem ua rau lub sijhawm ziab, txo qis thaum ntxov -theem hardness, lossis cuam tshuam cov dej tsis kam. Yog li ntawd, thaum tsim cov hlau txheej emulsions, zaj duab xis- tsim cov kev pab yuav tsum sib npaug nrog rau lwm yam khoom siv -xws li emulsion nws tus kheej, thickeners, thiab ntub dej cov neeg ua hauj lwm -kom ntseeg tau tias muaj kev ua tau zoo tsawg-kub zaj duab xis tsim thaum tuav lub txheej hardness, dej tsis kam, thiab durdh.
