Epoxy yeeb nkab yog ib yam khoom ua los ntawm hluav taws xob alkali-dawb iav fiber ntau daim ntaub impregnated nrog epoxy resin, ci, kub-pressed nyob rau hauv lub molding pwm, thiab ua tiav. Nws muaj cov khoom siv hluav taws xob siab, dielectric zog, thiab zoo machinability. Epoxy yeeb nkab yog tsim rau siv raws li insulating structural qhov chaw nyob rau hauv cov khoom siv hluav taws xob, thiab yuav siv tau nyob rau hauv ib puag ncig ntub thiab transformer roj. Kev faib tawm cua sov ntawm cov yeeb nkab epoxy suav nrog Chav B (130 degrees) thiab Chav F (155 degrees). 12
Cov tsos ntawm epoxy yeeb nkab yuav tsum tiaj tus thiab du, tsis muaj npuas, roj stains, thiab impurities. Xim tsis sib xws, khawb, thiab me ntsis tsis sib xws uas tsis cuam tshuam kev siv tau tso cai. Epoxy kav nrog phab ntsa thickness ntau tshaj 3 hli tau tso cai kom muaj cov kab nrib pleb ntawm lub ntsej muag kawg lossis hla ntu uas tsis cuam tshuam kev siv. 13
Hluav taws kub sib ntaus epoxy yeeb nkab yog ib qho tshwj xeeb epoxy yeeb nkab, uas yog tsim los ntawm txheej polyethylene los yog epoxy resin yas rau ntawm phab ntsa ntawm cov yeeb nkab dub. Nws yog tsim rau kev siv dej, kev tiv thaiv hluav taws, roj av, hluav taws xob, kev lag luam tshuaj, roj thiab lwm yam lag luam. Cov yeeb nkab no muaj cov yam ntxwv ntawm kev sib txhuam coefficient thiab kev sib txhuam coefficient, zoo heev tiv thaiv lub cev txawv teb chaws adhesion, siab mechanical zog, muaj zog txheej adhesion, zoo tshuaj corrosion kuj, anti-aging, thiab ntev kev pab cuam lub neej. 4
FR-4 epoxy yeeb nkab muaj cov khoom siv hluav taws xob zoo thiab cov khoom siv hluav taws xob, ua kom sov thiab noo noo tsis kam, thiab ua haujlwm zoo. Nws yog cov khoom siv laminated tubular ua los ntawm cov ntaub ntawv hluav taws xob impregnated nrog epoxy phenolic resin thiab lwm yam ntaub ntawv los ntawm kev kub siab thiab kub siab kub nias. FR-4 epoxy yeeb nkab muaj ntau yam kev siv, suav nrog cov khoom siv hluav taws xob hauv cov tshuab hluav taws xob thiab cov khoom siv hluav taws xob, thiab siv rau hauv qhov chaw ntub dej thiab cov roj hloov pauv. 56
Cov yam ntxwv ntawm epoxy resin yeeb nkab muaj xws li siab zog, corrosion kuj, tshav kub tsis kam, txias tsis kam, av qeeg tsis kam thiab yooj yim siv. Nws muaj kev tiv thaiv corrosion zoo heev thiab ua siab ntev rau cov tshuaj lom neeg xws li acids, alkalis, thiab ntsev. Epoxy resin yeeb nkab tuaj yeem tiv taus qhov kub thiab txias tau ntev, thiab nws qhov kub thiab txias deformation tuaj yeem ncav cuag ntau tshaj 200 degree. Nws tseem tuaj yeem tuav lub zog zoo thiab tawv tawv ntawm qhov kub thiab txias, thiab muaj kev cuam tshuam zoo rau qhov kub thiab txias. Tsis tas li ntawd, nws kuj muaj av qeeg zoo thiab tuaj yeem tswj kev ruaj ntseg hauv kev puas tsuaj ntuj xws li av qeeg. Epoxy raj yog lub teeb yuag, yooj yim rau kev txiav, nruab thiab txuas, thiab yuav tsum tsis muaj vuam lossis nplaum.
