Q2: Puas muaj qhov sib txawv ntawm FBE txheej thiab FBE hmoov txheej? A2: FBE txheej piav qhia txog cov txheej txheem kho zaum kawg ntawm cov yeeb nkab lossis cov khoom siv, thaum FBE hmoov txheej qhia txog cov khoom siv hmoov thiab cov txheej txheem hmoov siv los ua cov txheej txheem.

Q3: Cov khoom tshuaj ntsuam xyuas dab tsi feem ntau siv los txais FBE txheej ntawm cov kav dej coated? A3: Kev lees txais feem ntau yog tsom rau cov yeeb yaj kiab qhuav tuab (DFT) kev faib tawm, kev tsis sib txuas / porosity kuaj, kho thiab rov kuaj cov ntaub ntawv, kev soj ntsuam kev txiav rov qab / kawg, thiab kev sib txuas cov yeeb nkab ID rau txheej ntau thiab cov ntaub ntawv tshuaj xyuas.

Q4: Qhov twg epoxy primer thiab epoxy xim haum rau hauv cov yeeb nkab txheej project uas qhia FBE? A4: Epoxy primer feem ntau piav qhia txog cov epoxy puag hauv cov txheej txheem ntau lub tsho, qhov twg FBE tuaj yeem ua lub tsho tiv no, thaum cov xim epoxy feem ntau yog siv rau txheej txheej pob qij txha lossis kho hauv zos qhov twg cov hmoov fusion tsis rov qab siv dua ntawm qhov chaw.
