Yini impahla ye-EPDM? -Ukuhlaziywa kokujula kwezimpawu kanye nokusetshenziswa kwenjoloba ye-EPDM
I-EPDM (ethylene-propylene-Dieene Monomer) iyinjoloba yokwenziwa enesimo sezulu esihle kakhulu, i-ozone ne-chemical ukumelana, futhi isetshenziswa kabanzi kwezimoto, ezokwakha, ze-elekthronikhi kanye nezinye izimboni. Ngaphambi kokuqonda ukuthi iyiphi i-EPDM eyenziwe ngayo, kuyadingeka ukuqonda isakhiwo sayo esiyingqayizivele nenqubo yokukhiqiza ukuze uqonde kangcono izakhiwo zawo nokusebenzisa.
1. Ukwakheka kwamakhemikhali kanye nokwakheka kwamangqamuzana kwe-EPDM
I-ePDM irabha ithola igama layo ezingxenyeni zalo eziphambili: I-Ethylene, i-Pepylene kanye nama-Diene Minonomon. Lawa ma-monomers akha amaketanga anwebekile e-polymer ngokusebenzisa ukusabela kwe-copolymerication. I-Ethylene ne-Pepylene inikezela ngokuvikelwa okuhle kakhulu nokuvimbela i-oxidation, kuyilapho ama-diene monomers evumela i-EPDM ixhumeke ngokungenwa yi-vulcansation noma i-peroxide, yandisa amandla okuqina.
2. Izici zokusebenza ezibalulekile ze-EPDM
Ngenxa yokwakheka kwayo kwamakhemikhali okuyingqayizivele, i-EPDM inalo uhla lwezakhiwo ezinhle kakhulu ezenza ukuthi zivelele emasimini amaningi.Epdm zinokuphikiswa okuhle kakhulu kanye nokumelana kwe-UV, okusho ukuthi iyakwazi ukuvezwa elangeni isikhathi eside Ngaphandle kokuwohloka.Epdm nakho kubuye kube nokumelana okuhle kwe-ozone, okuvumela ukuthi kugcinwe ukusebenza kwayo ezimweni zemvelo ezinokhahlo ngaphandle kokuqhekeka.
Esinye isici esibalulekile ukumelana kwaso kwamakhemikhali, ikakhulukazi kuma-acid, ama-alkali kanye nama-sol sols ahlukahlukene. Ngakho-ke, i-EPDM ivame ukusetshenziswa ezimweni ezidinga ukuvezwa isikhathi eside kumazinga okushisa okusebenza, futhi ngokuvamile kungasebenza ngokujwayelekile phakathi kuka-40 ° C kanye no-150 ° C, okwenza kusetshenziswe kakhulu ezimotweni imboni, njengezimpawu zewindi, i-radiator hoses, njll.
3. Izicelo ze-EPDM ezimbonini ezahlukahlukene
Ukusetshenziswa okusabalele kwe-EPDM kuvezwa ngokuguquguquka kwayo kanye nezinto ezinhle kakhulu zomzimba. Embonini yezimoto, i-EPDM ivame ukusetshenziswa ekwenziweni kwezimpawu zasolwandle, izimpawu zeminyango, izinsimbi zomoya kanye ne-radiator hoses. Ngenxa yokuvimbela kwabo nokuguga kwabo, lezi zingxenye zigcina ukuqina kwazo nokusebenza kwazo isikhathi eside, kuthuthukisa impilo yensiza yemoto.
Embonini yezokwakha, i-EPDM isetshenziswa kabanzi ephahleni lwamanzi, umnyango kanye nama-samps wefasitela kanye nezinye izinhlelo zokusebenza ezidinga ukumelana manzi kanye ne-UV. Ukumelana kwayo kwesimo sezulu esihle nokuguquguquka kwesimo sezulu kuqinisekisa ukuqina kwesakhiwo kanye nokwenza uphawu kwezakhiwo.Epdm nakho kusetshenziswe ezintweni ezifunyayo zezintambo nezintambo, ukuhlinzeka ukusebenza okuhle kakhulu kogesi kanye nokumelana kwamakhemikhali.
4. Ukuvikelwa kwezemvelo kwe-EPDM nentuthuko esimeme
Ngokwesimo samanje sezidingo eziqinile zokuvikelwa kwemvelo, i-EPDM nayo iyathinteka ngenxa yokuvikelwa kwayo kwezemvelo kanye nokuthuthuka okuqhubekayo kwentuthuko. I-EPDM iyinto esetshenziswa kabusha, inqubo yokukhiqiza ingabe amagesi ayingozi namashidi ayingozi, ngokuhambisana nesidingo somphakathi wanamuhla wokuvikelwa kwemvelo. Ngokuthuthuka okuqhubekayo kwenqubo yokukhiqiza, amandla kanye nezinsizakusebenza ze-EPDM nazo zincishiswa kancane kancane, zifaka isandla ekuthuthukisweni okuqhubekayo komkhakha.
Ukugcina
Yini impahla ye-EPDM? Kuyinto eyenziwe ngendwangu yerabha esebenza kahle kakhulu nezinhlobonhlobo zezicelo. Ngokumelana nesimo sezulu sayo, ukumelana kwamakhemikhali kanye nobungani bemvelo, kudlala indima ebalulekile ezimbonini ezahlukahlukene. Noma ngabe embonini yezimoto, imboni yezokwakha, noma amasimu kagesi nele-elekthronikhi, i-EPDM isiphenduke isinqumo esibonakalayo esibonakalayo ngenxa yokusebenza kwayo okuvelele.
