Ubwino ndi kuipa kwa EPDM rabara hose

Hebei conqi Auto Parts Co., Ltd. ali ndi zaka 10 akutulutsa mphira ndi zinthu zapulasitiki kuti agawane nanu zabwino ndi zoyipa zamapaipi a EPDM: kukana kukalamba, kutsekereza kwamagetsi ndi magwiridwe antchito a ozoni ndizopambana.Kukana kwanyengo yabwino, kukana kwa ozoni, kukana kutentha, kukana kwa asidi ndi alkali, kukana kwa nthunzi wamadzi, kukhazikika kwamtundu, mphamvu zamagetsi, kudzaza mafuta ndi kutentha kwanthawi zonse kwamankhwala osiyanasiyana a polar monga ma alcohols, ma acid, alkali, oxidants, refrigerants, Detergents, nyama. ndi mafuta a masamba, ketoni ndi mafuta onse ali ndi kukana kwabwino;komabe, amakhala osakhazikika muzinthu zosungunulira za aliphatic ndi zonunkhira (monga petulo, benzene, etc.) ndi mafuta amchere.Pansi pa nthawi yayitali ya asidi woyikirapo, ntchitoyo idzachepanso, ndipo kukana kwa nthunzi wamadzi kumakhala bwino kuposa kukana kwake kutentha.Mu nthunzi yotentha kwambiri pa 230 ° C, palibe kusintha kwa mawonekedwe pambuyo pa maola pafupifupi 100.Pazifukwa zomwezo, mphira wa fluororubber, rabara ya silikoni, labala ya fluorosilicone, labala ya butyl, labala ya nitrile, ndi mphira wachilengedwe zidzawoneka kuwonongeka pakapita nthawi yochepa.Popeza palibe ma polar olowa m'malo a mphira wa ethylene-propylene, mphamvu yolumikizana ya molekyulu ndi yotsika, ndipo unyolo wa mamolekyu ukhoza kukhalabe wosinthika mosiyanasiyana, wachiwiri kokha ku rabala wachilengedwe ndi mphira wa butadiene, ndipo uthabe kukhalabe. pa kutentha kochepa.Chifukwa cha kusowa kwa magulu ogwira ntchito m'magulu a mphira a ethylene-propylene, mphamvu yogwirizanitsa imakhala yochepa, ndipo mphirayo ndi yosavuta kuphuka, ndipo kudzimangiriza ndi kugwirizanitsa ndizovuta kwambiri.
Fakitale yathu yakhala ikuyesa zambiri ndikupanga zambiri, ndipo kusinthidwa kwa zipangizo zamakono ndi zamakono zafupikitsa pang'onopang'ono kusiyana pakati pa ubwino ndi kuipa kwa machubu a epdm ndipo ndizokhazikika.Komabe, m'pofunikanso kusankha zoyenera kwambiri kwa makasitomala malinga ndi zosowa za makasitomala.mankhwala.
