Epoxy ester resin txheej yog ib txheej txheej txheej txheej nrog epoxy ester resin ua cov khoom siv ua yeeb yaj kiab. Epoxy ester resin yog compounded los ntawm epoxy resin thiab zaub roj fatty acid ester. Piv nrog rau cov txheej txheem epoxy, txheej txheej muaj tus nqi qis dua thiab tsis zoo alkali tsis kam. Feem ntau siv los ua ntau yam hlau primers thiab tshuaj tiv thaiv corrosion rau cov khoom siv sab nraum zoov hauv cov nroj tsuag tshuaj. Polyurethane resins siv los tiv thaiv corrosion feem ntau muaj ob yam: isocyanate-NCO thiab hydroxyl. Thaum siv, ob qho tib si sib xyaw ua ke thiab kho kom tsim tau polyurethane (polyurethane).
Cov yam ntxwv ntawm polyurethane coatings: ① Zoo lub cev thiab txhua yam khoom. Cov xim zaj duab xis yog tawv, hloov tau, ci, plump, hnav-resistant, thiab muaj zog adhesion. ② Zoo corrosion kuj. Resistant rau roj, kua qaub, tshuaj lom neeg thiab cov khoom siv khib nyiab. Alkali kuj yog me ntsis qis dua epoxy xim. ③ Kev laus ua haujlwm zoo dua li epoxy txheej. Feem ntau siv los ua lub tsho tiv no sab saum toj, tab sis kuj yog primer. ④Polyurethane resin tuaj yeem ua rau miscible nrog ntau yam resins, thiab cov qauv tuaj yeem hloov kho ntau yam kom tau raws li ntau yam kev xav tau. ⑤ Nws tuaj yeem kho tau ntawm chav tsev kub lossis cua sov, thiab tuaj yeem kho tau ntawm qhov kub qis dua (0 degree ). ⑥ Kev ruaj khov ntawm cov khoom siv polyisocyanate tsis zoo thiab yuav tsum tau insulated los ntawm ya raws kom tsis txhob muaj jelly. Polyurethane txheej yog kim tab sis muaj lub neej ua haujlwm ntev. Ib tug siv cov txheej txheem tshwj xeeb hauv ob sab phlu, uas yog tsim los ntawm winding filaments ntawm cov ntaub ntawv sib xyaw lossis extruding thermoplastics los tsim cov ntaub ntawv corrosion-resistant hauv cov yeeb nkab steel. Cov khoom siv tiv thaiv corrosion no tuaj yeem cais cov kua corrosive thiab roj ntawm cov roj av los ntawm cov yeeb nkab steel. Nws tuaj yeem muab sab hauv los tiv thaiv corrosion hauv ob sab phlu rau oilfield steel kav thiab kav dej.
