Fluorinated ethylene propylene (FEP).inokuchazwa njenge-fluoropolymer resin enezona zinto zibalaseleyo zomzimba.iipropathi zeekhemikhali kunye nombane we-PTFE kodwa zinokulungiswa kusetyenziswa izixhobo eziqhelekileyo zokulungisa i-thermoplastics.
I-FEP yokunciphisa ubushushu izigqubuthelo zomqulu zifanelekile apho kufuneka ukhuseleko kwiindawo ezingalunganga.Ukulula kwayo ukufakela kunciphisa iindleko zokugcina kunye nexesha eliphantsi.Ikwabonelela ngokumelana nokugqwesa okugqwesileyo, ukukhuselwa kuxhatshazo lomzimba, ukothuka kunye nokuxhathisa ukonakala, iipropathi ezigqwesileyo zombane, kunye nokucoceka okuphezulu kunye nokungafihli.Ukucutheka kumalunga nama-20%.Ukushisa kwe-shrinkage yi-350 ° F. I-force yokubamba i-5-8 psi kunye nokugqitywa komphezulu ngama-intshi angama-40.Ubushushu obuqhubekayo bepolymer FEP yi-400 ° F. Nangona kunjalo, phantsi kokulayisha okuphezulu, oku kwehla kakhulu.Ukusetyenziswa kwe-roll cover cover apho uxinzelelo oluphezulu lubandakanyekayo, ubushushu akufunekanga budlule kwi-200°F.Kwezo zicelo zoxinzelelo oluphezulu kunye nobushushu, ityhubhu ye-ID efakiweyo kufuneka isetyenziswe kunye ne-adhesive.
Ukufakela amaqweqwe e-FEP roll kufuneka kuqala ukhethe i-diameter ekufutshane enkulu kunobungakanani obufunekayo.Khetha ubude obusekwe kuqikelelo olumalunga ne-3% yobude.Kwizigqubuthelo eziqengqelekayo, kwakhona vumela i-2"-3" eyongezelelweyo ubude kwiicuffs zokuphela.Isikere okanye imela yoncedo ebukhali ingasetyenziselwa ukusika iityhubhu.Ukunciphisa i-tubing kwinxalenye, sebenzisa i-250-400 ° F, kuxhomekeke kwisicelo.Oku kunokwenziwa ngokusebenzisa i-oven yomoya oshushu okanye umpu worhwebo womoya oshushu.Kwizigqubuthelo zomqulu, kucetyiswa ukuba kusetyenziswe izibhamu ezimbini zomoya oshushu, ngapha nangapha kwe-roller.I-roller kunye ne-tube kufuneka ijikelezwe ngokufanayo ngelixa usebenzisa ukushisa.
