PE daahan, budada epoxy thermosetting ah, rinjiga aan sunta ahayn, daawaynta si ay u sameeyaan daahan of qaab-dhismeedka cross-ku xidhan miisaanka culus, oo leh caabbinta kiimikada heer sare ah iyo guryaha farsamo sare, gaar ahaan iska caabin abrasion ugu fiican iyo adhesion.Dahaarku waa 100% adag, dareere-la'aan, wasakh-la'aan, ka faa'iidaysiga budada ilaa 95%, waxaana lagu aasay dahaarka tayada ka hortagga daxalka.

Budada Epoxy ayaa lagu dabaqay iyadoo la adeegsanayo habka buufinta elektrostatic.Maaddaama habka Dip budada epoxy ay dhibsatay adhesion, budada epoxy weligood si ballaaran loo isticmaali karo.Sanadihii la soo dhaafay, oo ay la socdaan saddex qumbaha gaarka ah epoxy fosfooraska budada ah ayaa si guul leh u horumariyay qabashada ugu horreysa ee xajinta ee dhibaatooyinka habka budada epoxy budada, dip epoxy budada ayaa bilaabay inay kor u qaaddo tignoolajiyadan soo ifbaxaysa.

Daahan PE ee nooca daahan birta birta, huurka, heerkulka, iwm go'aaminta daahan nuugista biyaha, dhumucdiisuna waxay hoos yimaadaan shuruudaha la mid ah daahan sida function caabbinta lays.Daraasaduhu waxay muujiyeen in samaynta epoxy-ga iskuxiran ee xaddi gaar ah oo kanaalo ah, kanaaladan molecules-ka biyaha galay resin epoxy waxay bixiyaan kanaal.Imaansho ka tunnel galay xal daahan / interface biraha, falcelinta interface la film alaabta daxalka biraha, lakabka this ka hortagtaa biraha alaabta daxalka iyo xal falcelinta, iska caabin daahan hoos u.Sida ions badan oo daxalka ah ay gaaraan interface-ka, lakabkan filimka wax soo saarka daxalka ayaa si tartiib tartiib ah loo burburiyaa, kor u kaca daxalka, taasoo keentay daahan epoxy laga xayuubiyay durbaanka.Dahaarka FBE ayaa lagu daaweeyay weli qani ku ah ether iyo hydroxyl, kooxdan falcelinta falcelinta leh ee isku xidhka kiimikaad oo leh lakabka dusha tuubada oo si adag isugu xidhan si ay u sameeyaan daahan u adkaysta daxalka.Furitaanka dahaarka, isafgaradka iyo pinholes iyo sababo kale, waxay leeyihiin heerar kala duwan oo daahan oo uu leeyahay permeability ah biyaha, haddii ilaalinta cathodic xad-dhaaf ah, kobcinta hydrogen cathodic, oo leh ururinta atamka hydrogen firfircoon, ilaa xad, ee hydrogen la ether group. iyo falcelinta hydroxyl, taas oo wiiqaysa ku dheggan dahaarka iyo tuubada birta, taasoo keentay in xoogga adhesion baaba'o.Natiijadu waa dahaarka ka soo baxa tuubada oo go'an.
