Txheej zaj duab xis tsim cov xim coated phaj feem ntau suav nrog txheej adhesion thiab txheej ziab.
Xim coated phaj txheej adhesion
Thawj kauj ruam ntawm cov adhesion ntawm steel sawb substrate thiab txheej yog cov ntub dej ntawm cov xim coated phaj txheej rau saum npoo ntawm substrate.Cov txheej ntub dej tuaj yeem hloov cov huab cua thiab dej thaum chiv thawj adsorbed rau saum npoo ntawm steel sawb substrate.Nyob rau tib lub sijhawm, volatilization ntawm cov kuab tshuaj nyob rau saum npoo ntawm substrate muaj cov nyhuv ntawm kev sib cais los yog o.Yog hais tias lub solubility tsis nyob rau hauv cov zaj duab xis tsim resin ntawm cov xim coated phaj txheej thiab nto ntawm lub substrate raug xaiv kom zoo, ib tug inter-mixed txheej yuav raug tsim nyob rau hauv nruab nrab ntawm cov xim coated phaj substrate thiab txheej zaj duab xis, qhov no yog heev. tseem ceeb rau qhov zoo adhesion ntawm txheej.
B Xim coated phaj txheej kom qhuav
Lub adhesion kev tsim kho ntawm cov xim coated phaj 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 phaj, thiab tseem txuas ntxiv cov txheej txheem ntawm tig mus rau hauv cov khoom txuas ntxiv, uas tuaj yeem ua tiav tag nrho cov txheej txheem txheej txheej. txheej txheem.Cov txheej txheem no los 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 ntaub ntawv sib txawv thiab cov txheej txheem ntawm cov txheej txheem muaj lawv tus kheej zaj duab xis-tsim mechanism, uas yog txiav txim siab los ntawm cov khoom ntawm cov yeeb yaj kiab tsim cov khoom siv hauv cov txheej txheem.Feem ntau, peb faib cov zaj duab xis-txheej txheej txheej rau hauv ob pawg: khoom thiab teb
(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 hnyav los yog lwm yam dispersion xov xwm nyob rau hauv cov zaj duab xis, thiab cov zaj duab xis viscosity maj mam nce los ua ib tug khoom zaj duab xis.Piv txwv li: acrylic xim, chlorinated roj hmab xim, vinyl xim, thiab lwm yam.
(2) Kev hloov pauv.Feem ntau, nws yog hais txog cov tshuaj tiv thaiv uas tshwm sim thaum lub sij hawm ua zaj duab xis txheej txheem, thiab zaj duab xis txheej txheej feem ntau yog nyob ntawm cov tshuaj tiv thaiv.Qhov kev ua yeeb yaj kiab zoo li no yog cov txheej txheem ntawm cov yeeb yaj kiab tsim cov tshuaj hauv cov txheej txheem polymerizing zaj duab xis hu ua polymer tom qab kev tsim kho.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 tsim cov yeeb yaj kiab.Lub coil txheej yog ib qho zoo uas tso siab rau ntau txoj hauv kev los tsim cov yeeb yaj kiab.
