Dab tsi yog Epoxy Coatings

Epoxy-raws li txheej txheej tuaj yeem yog ob lub tshuab (tseem hu ua ob ntu epoxy txheej) lossis siv los ua ib qho hmoov txheej. Ob feem epoxy txheej yog siv rau kev ua haujlwm siab ntawm cov hlau substrate. Lawv yog ib qho kev xaiv zoo rau cov hmoov txheej formulations nyob rau hauv industrial thiab automotive daim ntaub ntawv ua tsaug rau lawv tsis tshua muaj volatility thiab compatibility nrog waterborne formulations. Epoxy hmoov txheej yog dav siv rau cov hlau txheej hauv "cov khoom dawb" xws li cov cua sov thiab cov khoom siv loj loj. Epoxy txheej kuj tau dav siv rau kev tiv thaiv corrosion ntawm cov kav dej thiab fittings: nyob rau hauv kev lag luam roj thiab roj, tab sis kuj rau cov kav dej, pob zeb reinforcing rebar rau npe ob peb.

Epoxy yog ib qho copolymer uas tau txais los ntawm reticulation ntawm epoxide (resin) nrog polyamine (hardener). Lawv paub zoo rau lawv cov qib siab ntawm adhesion, tshwj xeeb tshaj yog nyob rau hauv cov hlau, muaj tshuaj lom neeg thiab thermal tsis kam, thiab zoo heev hluav taws xob rwb thaiv tsev muaj peev xwm. Epoxy formulations yog li ntawd ib qho kev daws teeb meem rau ntau yam khoom siv hluav taws xob thiab cov khoom siv hluav taws xob (xws li: coil coil, solder mask on circuit boards). Ovrall epoxy txheej yog kim dua li lwm cov tshuab xws li Alkyd lossis Acrylic, tab sis lawv kuj qhia tau zoo dua. Ntawm qhov tod tes, epoxy txheej ib txwm raug kev txom nyem los ntawm UV kab teeb. Qhov kev qaug zog no tau them nyiaj los ntawm kev siv cov txheej txheem UV tiv thaiv los yog topcoat
