Kodi EPDM ndi chiyani? - Kusanthula kwakuya kwa mawonekedwe ndi ntchito za mphira wa epdm
EPDM (Ethylene-Propylene Monomer) ndi mphira wopangidwa ndi nyengo yabwino kwambiri, ozoni ndi kukana kwa mankhwala, ndipo imagwiritsidwa ntchito mogwirizana, zomangamanga, zamagetsi ndi mafakitale ambiri. Musanamvetsetse zomwe Epdm imapangidwa, ndikofunikira kumvetsetsa kapangidwe kake kake ndi njira yopanga kuti imvetsetse bwino zomwe zimagwiritsidwa ntchito.
1. Kupanga kwamankhwala ndi kapangidwe kake ka epdm
EPDM rabara imatchula dzina lake kuchokera pazigawo zake zazikulu: Ethylene, Prosinean ndi Diene Monomers. Zosangalatsazi zimapanga maunyolo otanuka chifukwa cha polmermisations zimachitika. Ethylene ndi Propylene amapereka kutentha kwambiri kwa kutentha, pomwe sodina moomemers amalola Epdm kuti ikhale yolumikizidwa ndi Vulcanation kapena Peroxide, kuwonjezera nyongazo za nkhaniyi.
2. Makhalidwe ogwirira ntchito a EPDM
Chifukwa cha kapangidwe kake ka mankhwala, EPDM imakhala ndi mitundu yabwino kwambiri yomwe imapangitsa kuti ikhale m'minda yambiri.pddm imakhala ndi nyengo yabwino kwambiri komanso kukana kwa nthawi yayitali. Popanda kuwonongeka.
Chofunikira china ndi kukana kwake mankhwala, makamaka acids, alkalis ndi polarnt osiyanasiyana. Chifukwa chake, Epdm nthawi zambiri amagwiritsidwa ntchito pamavuto kwa mankhwala.pddm ali ndi kutentha kwambiri, ndipo nthawi zambiri amatha kugwira ntchito pakati pa -40 ° C ndi 150 ° Makampani, monga zisindikizo zawindo, radiator hoses, etc.
3. EPDM Kugwiritsa Ntchito M'mafakitale Osiyanasiyana
Kugwiritsa ntchito epdm kumadziwika kuti ndi njira yabwino kwambiri yochitira zinthu mosiyanasiyana. Mu makampani ogulitsa magalimoto, Epdm amagwiritsidwa ntchito popanga Zisindikizo, Zisindikizo pakhomo, zopukuta zamphepo, mitengo ya radiator. Chifukwa cha kutentha kwawo ndi kukalakana kwawo, zinthu izi zimasunga zolemeledwa kwa nthawi yayitali, kulimbikitsa moyo wagalimoto.
Mu makampani omanga, Epdm amagwiritsidwa ntchito kwambiri padenga lopanda madzi, khomo ndi zisindikizo za pawindo ndi mapulogalamu ena omwe amafunikira kukana madzi ndi UV. Nyengo yake yabwino ndi kusinthasintha kutsimikizika kwa magwiridwe antchito.
4. Chitetezo cha EPDM ndi chitukuko chokhazikika
M'malemba omwe alipo kale zolimba zachilengedwe zomwe zimachitika zachilengedwe, Epdm amaderanso nkhawa chifukwa choteteza zachilengedwe komanso kuthekera kokhazikika. EPDM ndi zinthu zobwezeretsanso, ntchito yopanga sizachilendo ndi ma cases, mogwirizana ndi anthu omwe ali masiku ano amafunikira kuteteza chilengedwe. Mwa kusintha mosalekeza kwa ntchito yopanga, mphamvu ndi kugwiritsa ntchito Epdm imachepetsedwa pang'onopang'ono, ndikuthandizira kukulitsa mafakitale.
Mapeto
Kodi EPDM ndi chiyani? Ndi zinthu zopangidwa ndi mphira zomwe zimagwirira ntchito bwino komanso kugwiritsa ntchito mitundu ingapo. Ndi nyengo yake kukana, kukana kwa mankhwala ndi ubwenzi wachilengedwe, imagwira ntchito yofunika m'mafakitale osiyanasiyana. Kaya mumatakampani opanga magalimoto, kapena minda yamagetsi komanso yamagetsi, EPDM yasankhidwa mosafunikira chifukwa cha ntchito yake yapamwamba.
