Zaj duab xis tsim ntawmxim coated boardtxheej txheej feem ntau suav nrog ob yam: txheej adhesion thiab txheej ziab.
Adhesion ntawm A xim coated board txheej
Thawj kauj ruam nyob rau hauv adhesion ntawm lub steel sawb substrate thiab txheej yog cov ntub dej ntawm cov xim coated board txheej ntawm lub substrate nto.Cov txheej ntub dej tuaj yeem hloov tau cov huab cua thiab dej thaum chiv thawj adsorbed ntawm steel sawb substrate nto.Nyob rau tib lub sij hawm, lub volatilization ntawm cov kuab tshuaj nyob rau hauv lub substrate nto ua rau dissolution los yog o.Yog hais tias lub solubility tsis nyob rau hauv cov zaj duab xis-forming resin ntawm cov xim coated board txheej thiab cov substrate nto raug xaiv kom tsim nyog, nws yuav tsim ib tug immiscible txheej ntawm cov xim coated board substrate nto thiab txheej zaj duab xis, qhov no yog ib qho tseem ceeb heev rau lub zoo adhesion ntawm txheej.
Kev ziab ntawm Bxim coated boardtxheej
Lub adhesion kev tsim kho ntawm cov xim coated board txheej tsuas yog ua tiav thawj kauj ruam ntawm txheej txheej zaj duab xis tsim nyob rau hauv txheej txheej txheej txheej ntawm cov xim coated board, thiab cov txheej txheem ntawm kev ua ib tug ruaj nrees zaj duab xis yuav tsum tau mus ntxiv, uas yuav ua kom tiav tag nrho cov txheej txheem txheej txheej txheej.Cov txheej txheem ntawm kev hloov ntawm "wt film" mus rau "dry film" feem ntau yog hu ua "qhuav" lossis "kho".Cov txheej txheem ziab thiab curing no yog qhov tseem ceeb ntawm txheej txheej zaj duab xis txheej txheem.Cov txheej txheem sib txawv thiab cov txheej txheem muaj lawv tus kheej cov txheej txheem ua yeeb yaj kiab, uas tau txiav txim siab los ntawm cov khoom ntawm cov yeeb yaj kiab tsim cov khoom siv hauv txheej.Feem ntau, peb faib cov txheej txheem ua yeeb yaj kiab ntawm txheej txheej ua ob pawg:
(1) Tsis hloov pauv.Feem ntau, nws yog hais txog lub cev zaj duab xis-tsim txoj kev, uas feem ntau yog nyob ntawm lub volatilization ntawm cov kuab tshuaj los yog lwm yam dispersing xov xwm nyob rau hauv lub txheej zaj duab xis, maj mam nce lub viscosity ntawm txheej zaj duab xis thiab tsim ib tug txheej txheej zaj duab xis.Piv txwv li, acrylic coatings, chlorinated roj hmab coatings, ethylene txheej, thiab lwm yam.
(2) Kev hloov pauv.Feem ntau, nws hais txog qhov tshwm sim ntawm cov tshuaj tiv thaiv kab mob thaum lub sij hawm tsim cov yeeb yaj kiab, thiab cov txheej txheem feem ntau yog nyob ntawm cov tshuaj lom neeg los tsim cov yeeb yaj kiab.Cov txheej txheem ua yeeb yaj kiab no yog hais txog polymerization ntawm cov yeeb yaj kiab tsim cov tshuaj hauv cov txheej txheem, hu ua polymers, tom qab thov.Nws tuaj yeem hais tias yog ib txoj hauv kev tshwj xeeb ntawm polymer synthesis, uas ua tiav raws li cov tshuaj tiv thaiv ntawm polymer synthesis.Piv txwv li, alkyd txheej, epoxy txheej, polyurethane txheej, phenolic txheej, thiab lwm yam. Txawm li cas los xij, feem ntau cov txheej txheem niaj hnub tsis tsim cov yeeb yaj kiab hauv ib txoj kev, tab sis cia siab rau ntau txoj hauv kev los ua cov yeeb yaj kiab thaum kawg, thiab coil txheej yog ib hom yeeb yaj kiab uas tso siab rau ntau txoj hauv kev los ua cov yeeb yaj kiab thaum kawg.
