Fluorinated ethylene propylene (FEP).ingachazwa njenge-fluoropolymer resin eneningi elihle kakhulu elibonakalayo.amakhemikhali kanye nezakhiwo zikagesi ze-PTFE kodwa zingasetshenzwa kusetshenziswa imishini evamile yokucubungula i-thermoplastics.
Amakhava e-FEP ashwabanisa ukushisa alungile lapho kudingeka khona ukuvikelwa ezindaweni ezingezinhle.Ukulula kwayo ukufaka kunciphisa izindleko zesondlo kanye nesikhathi esiphansi.Iphinde inikeze ukumelana nokugqwala okuhle kakhulu, ukuvikeleka ekuhlukunyezweni ngokomzimba, ukumelana nokushaqeka nokuhuzuka, izakhiwo zikagesi ezinhle kakhulu, nokuhlanzeka okuphezulu nokuba sobala.Ukuncipha cishe ku-20%.Izinga lokushisa lokuncipha lingu-350° F. Amandla okubamba ama-psi angu-5-8 kanye nokuqeda okungaphezulu okungama-intshi angu-40 micro.Izinga lokushisa eliqhubekayo le-polymer FEP lingu-400° F. Nokho, ngaphansi kokulayisha okuphezulu, lokhu kwehla kakhulu.Ngohlelo lokusebenza lwekhava ye-roll lapho ukucindezela okuphezulu kubandakanyeka, izinga lokushisa akufanele lidlule ku-200°F.Kulezo zicelo zokucindezela okuphezulu nokushisa, ishubhu ye-ID eqoshiwe kufanele isetshenziswe ngokunamathela.
Ukufaka amakhava e-FEP roll kufanele uqale ukhethe ububanzi obuseduze obukhudlwana kunosayizi ofisa.Khetha ubude obususelwe ekuncipheni okungu-3% ngobude.Kumakhava ama-roll, futhi vumela okungeziwe okungu-2”-3” ngobude kuma-cuffs wokugcina.Isikele noma ummese obukhali ungasetshenziswa ukusika amashubhu.Ukuze ushwabanise amashubhu engxenyeni ethile, sebenzisa u-250-400° F, kuye ngokusetshenziswa.Lokhu kungenziwa ngokusebenzisa ihhavini lomoya oshisayo noma isibhamu somoya oshisayo esithengiswayo.Ukuze uthole izembozo ze-roll, kunconywa izibhamu ezimbili zomoya oshisayo, ohlangothini ngalunye lwe-roller, zisetshenziswe.I-roller kanye neshubhu kufanele kujikelezwe ngokufanayo ngenkathi kusetshenziswa ukushisa.
