Bending Test Thiab Adhesion ntawm FBE hmoov txheej
Adhesion ntawm FBE hmoov txheej A cupping tester feem ntau yog siv los txiav txim siab qhov adhesion ntawm FBE hmoov txheej, thiab Fig.7 qhia txog lub hauv paus ntsiab lus ntawm kev ntsuas cupping. Lub taub hau ntawm cupping tester yog spherical, thawb rov qab ntawm coated panels los ntsuam xyuas seb cov zaj duab xis zoo tawg los yog sib cais los ntawm substrate. Fig.8 yog ib qho kev xeem cupping ntawm epoxy hmoov txheej. Nws tuaj yeem pom tias FBE hmoov txheej uas tsis tau ntim nrogNyeem ntxiv…
Kev npaj ntawm Carboxylterminated rau Fusion-bonded-epoxy hmoov txheej
Kev npaj thiab kev ua yam ntxwv ntawm Carboxylterminated Poly (butadiene-co-acrylonitrile) -epoxy Resin Prepolymers rau Fusion-bonded-epoxy Powder Txheej 1 Taw qhia Fusion-bonded-epoxy (FBE) hmoov txheej uas yog thawj zaug tsim los ntawm 3M Co., yog siv dav thaum Kev tiv thaiv corrosion mus ntev yog qhov tseem ceeb xws li hauv cov roj, hlau, roj thiab cov kav dej hauv kev lag luam. Txawm li cas los xij, qhov yuav tsum tau ua ntawm FBE hmoov txheej yog qhov nyuaj vim tias lawv qhov sib txuas sib txuas siab. Lub hauv paus brittleness ntawm kho coatings yog ib qho ntawm cov teeb meem loj tiv thaiv daim ntawv thov dav rau epoxyNyeem ntxiv…
Taw qhia ntawm Fusion bonded epoxy hmoov txheej
Fusion bonded epoxy txheej, tseem hu ua fusion-bond epoxy hmoov txheej thiab feem ntau hu ua FBE txheej, yog epoxy raws hmoov txheej uas tau dav siv los tiv thaiv cov yeeb nkab steel siv hauv kev tsim cov kav dej, cov pob zeb ua kom muaj zog (rebar) thiab ntawm ib qho ntau yam ntawm cov kav dej sib txuas, li qub thiab lwm yam los ntawm corrosion. FBE txheej yog thermoset polymer txheej. Lawv tuaj nyob rau hauv qeb ntawm 'tiv thaiv txheej' hauv cov xim thiab txheej nomenclature. Lub npe 'fusion-bond epoxy' yog vim muaj cov khoom sib txuas sib txuas thiabNyeem ntxiv…
