Boitsebiso ba EPDM ke eng? -Tlhahlobo e tebileng ea litšobotsi le ts'ebeliso ea rabara ea EPDM
EPDM (ethylene-propylene-diene monomer) ke rabara ea maiketsetso e nang le boemo ba leholimo bo botle, ozone le lik'hemik'hale tse hanyetsanang le lik'hemik'hale, 'me e sebelisoa haholo indastering ea likoloi, kaho, ea elektronike le tse ling. Pele o utloisisa hore na EPDM e entsoe ka eng, hoa hlokahala ho utloisisa sebopeho sa eona se ikhethang sa limolek'hule le mokhoa oa ho etsa tlhahiso e le hore u utloisise hantle thepa le litšebeliso tsa eona.
1. Sebopeho sa lik'hemik'hale le sebopeho sa limolek'hule tsa EPDM
Rabara ea EPDM e fumana lebitso la eona ho tsoa likarolong tsa eona tse kholo: ethylene, propylene le diene monomers. Li-monomers tsena li theha liketane tse otlolohileng tsa polymer ka karabelo ea copolymerization. Ethylene le propylene li fana ka mocheso o babatsehang le ho hanyetsa oxidation, ha li-diene monomers li lumella EPDM hore e kopane ka vulcanisation kapa peroxide, e ntse e eketsa matla le ho tšoarella ha thepa.
2. Litšobotsi tsa bohlokoa tsa ts'ebetso ea EPDM
Ka lebaka la lik'hemik'hale tse ikhethang tsa lik'hemik'hale, EPDM e na le mefuta e mengata e babatsehang e etsang hore e hlahelle libakeng tse ngata.EPDM e na le boemo bo botle ba leholimo le ho hanyetsa UV, ho bolelang hore e khona ho pepesehela khanya ea letsatsi ka nako e telele. ntle le ho senyeha.EPDM e boetse e na le khanyetso e babatsehang ea ozone, e lumellang hore e boloke ts'ebetso ea eona maemong a thata a tikoloho ntle le ho senya.
Ntho e 'ngoe ea bohlokoa ke ho hanyetsa lik'hemik'hale, haholo-holo ho li-acids, alkalis le li-solvents tse sa tšoaneng tsa polar. Ka hona, EPDM e atisa ho sebelisoa maemong a hlokang nako e telele ea lik'hemik'hale.EPDM e na le mefuta e mengata ea mocheso oa ho sebetsa, 'me hangata e ka sebetsa ka mokhoa o tloaelehileng pakeng tsa -40 ° C le 150 ° C, e leng se etsang hore e sebelisoe haholo-holo likoloing. indasteri, joalo ka litiiso tsa lifensetere, li-hose tsa radiator, jj.
3. Likopo tsa EPDM liindastering tse sa tšoaneng
Tšebeliso e atileng ea EPDM e bakoa ke ho feto-fetoha ha eona le litšobotsi tse ntle tsa 'mele. Ka indasteri ea likoloi, EPDM e atisa ho sebelisoa ha ho etsoa liqibi, litiiso tsa mamati, li-wiper tsa windscreen le li-hose tsa radiator. Ka lebaka la ho hanyetsa mocheso le botsofali, likarolo tsena li boloka elasticity le ts'ebetso ea tsona ka nako e telele, ho ntlafatsa bophelo ba tšebeletso ea koloi.
Lefapheng la kaho, EPDM e sebelisoa haholo ho thibela metsi a marulelong, litiiso tsa menyako le lifensetere le lisebelisoa tse ling tse hlokang ho thibela metsi le ho hanyetsa UV. Ho hanyetsa ha eona boemo ba leholimo bo botle le ho feto-fetoha ha maemo ho netefatsa hore ho tsitsisa ha moralo le ts'ebetso ea tiiso ea mehaho.EPDM e boetse e sebelisoa ka thepa ea sheathing ea lithapo le lithapo, ho fana ka ts'ebetso e babatsehang ea ho kenya motlakase le ho hanyetsa lik'hemik'hale.
4. Tšireletso ea tikoloho ea EPDM le tsoelo-pele e tsitsitseng
Boemong ba hajoale ba litlhoko tse ntseng li eketseha tsa ts'ireletso ea tikoloho, EPDM e boetse e amehile ka lebaka la ts'ireletso ea eona ea tikoloho le bokhoni ba nts'etsopele ea moshoelella. EPDM ke thepa e ka sebelisoang hape, ts'ebetso ea tlhahiso ha e na likhase tse kotsi le litšila, ho latela tlhoko ea sechaba ea kajeno ea ts'ireletso ea tikoloho. Ka ntlafatso e tsoelang pele ea ts'ebetso ea tlhahiso, tšebeliso ea matla le lisebelisoa tsa EPDM e ntse e fokotseha butle-butle, e leng se tlatsetsang ntlafatsong e tsitsitseng ea indasteri.
Qetello
Boitsebiso ba EPDM ke eng? Ke thepa ea rabara ea maiketsetso e nang le ts'ebetso e babatsehang le mefuta e mengata ea likopo. Ka ho hanyetsa boemo ba leholimo, khanyetso ea lik'hemik'hale le botsoalle ba tikoloho, e phetha karolo ea bohlokoa liindastering tse sa tšoaneng. Ebang ke indastering ea likoloi, indasteri ea kaho, kapa masimong a motlakase le a elektroniki, EPDM e fetohile khetho ea bohlokoa ea thepa ka lebaka la ts'ebetso ea eona e ikhethang.
