Hose ea rabara ea EPDM, e le hose ea rabara ea maiketsetso e sebetsang hantle haholo, e boemong bo ke keng ba nkeloa sebaka liindastering tse ngata ka melemo ea eona e ikhethang ea ts'ebetso le likarolo tse pharaletseng tsa ts'ebeliso. Hose ena e sebelisa rabara ea ethylene propylene diene monomer (EPDM) joalo ka thepa e ka sehloohong e tala. E ntshetswa pele ka hloko kaZebungTs'ebetso e tsoetseng pele ea tlhahiso ea theknoloji, e le hore sehlahisoa se be le thepa e ntle ea 'mele le ea lik'hemik'hale' me se ka sebetsa ka mokhoa o tsitsitseng libakeng tse fapaneng tse rarahaneng.
1). Tshebetso e babatsehang
1. Ho hanyetsa mocheso o phahameng:Hose ea rabara ea EPDMe khona ho mamella mocheso ho fihla ho 150°C mme e ntse e ka sebetsa ka mokhoa o tsitsitseng tikolohong ea mocheso o phahameng o tsoelang pele. Karolo ena e etsa hore e tšoanelehe ka ho khetheha bakeng sa liketsahalo tse hlokang mecha ea phatlalatso ea mocheso o phahameng, joalo ka liphaephe tsa ho futhumatsa likoloi, hose ea metsi a pholileng a indasteri, joalo-joalo. Libakeng tsa mocheso o phahameng,Lithapo tsa rabara tsa EPDMe ka boloka botsitso ba thepa ea bona ea 'mele le ea lik'hemik'hale.
2. Ho hanyetsa lik'hemik'hale:Lithapo tsa rabara tsa EPDMe na le mamello e ntle ho lik'hemik'hale tse ngata, e ka sebetsa ka mokhoa o tsitsitseng libakeng tse sa tšoaneng tse rarahaneng, 'me ha e senyehe ke mecha ea litaba. Hose ena e ka hanela kutu ho tsoa mefuteng e fapaneng ea litharollo tsa asiti le alkali, lihatsetsi le lintho tse ling, ka hona e sebelisoa haholo lits'ebetsong tse tsamaisang thepa lik'hemik'hale, lijo, meriana le liindasteri tse ling.
3. Ho hanyetsa botsofali:Hose ea rabara ea EPDMe bonts'a khanyetso e matla ea botsofali tlas'a khanya ea letsatsi, moea le maemo a mocheso o phahameng, 'me e ka boloka botsitso le bophelo ba tšebeletso ea thepa ka nako e telele. Sebopeho sa eona sa lik'hemik'hale se tsitsitse, ketane e kholo e entsoe ka lik'hemik'hale tse tsitsitseng tsa lik'hemik'hale tse tletseng lik'hemik'hale, 'me li na le litlamo tse peli tse sa tsitsang ka lehlakoreng la ketane, kahoo ha ho bonolo ho tsofala, ho thatafala, ho senya le liketsahalo tse ling.
4. Ho hanyetsa boemo ba leholimo le ho hanyetsa ho apara:Hose ea rabara ea EPDMe na le khanyetso e matla ea boemo ba leholimo 'me e ka hanela khoholeho ea tikoloho e thata joalo ka mahlaseli a ultraviolet, moea le pula, leqhoa le lehloa. Ka nako e ts'oanang, khanyetso ea eona e ntle ea ho apara e thibela ka katleho likhohlano le ho roala, e sireletsa mokhoa oa phetisetso ka har'a lipeipi, 'me e lelefatsa bophelo ba tšebeletso.
5. Lintho tse phahameng tsa mochini:Hose ea rabara ea EPDMe na le matla a matle a ho tsikitlanya, ts'ebetso ea ho kobeha, elasticity le ho hanyetsa ho roala, 'me e khona ho mamella khatello e matla ea matla le khatello ea maikutlo. Thepa ena e babatsehang ea mechine e nolofalletsaHose ea rabara ea EPDMho boloka ts'ebetso e tsitsitseng tlasa maemo a fapaneng a khatello ea maikutlo.
2). Libaka tse pharaletseng tsa ts'ebeliso
1. Indasteri ea likoloi:Hose ea rabara ea EPDMe na le boemo ba bohlokoa indastering ea likoloi 'me e sebelisoa haholo ho litsamaiso tsa braking tsa likoloi, litsamaiso tse pholileng, tsamaiso ea moea, tsamaiso ea mafura, joalo-joalo. mocheso oa eona o phahameng oa ho hanyetsa le ho hanyetsa acid le alkali ho etsa hore li-hoses tsena li sebetse ka mokhoa o tsitsitseng ka nako e telele. mocheso le tikoloho e rarahaneng ea lik'hemik'hale.
2. Tlhahiso ea indasteri: indastering ea tlhahiso ea indasteri,Lithapo tsa rabara tsa EPDMli loketse lipalangoang tsa mefuta e fapaneng ya mecha ea litaba lik'hemik'hale, ho akarelletsa le metsi, mouoane, acid le alkali ditharollo, joalo-joalo Hangata li sebelisoa limela tsa lik'hemik'hale, limela tsa meriana, liindasteri tsa lijo le masimo a mang ho etsa bonnete ba lipalangoang tse sireletsehileng le tse ka tšeptjoang nakong ea tlhahiso. tshebetso.
3. Indasteri ea kaho: indastering ea kaho,Lithapo tsa rabara tsa EPDMe ka sebelisoa bakeng sa phepelo ea metsi le tsamaiso ea ho ntša metsi meahong. Ho hanyetsa ha eona mocheso o phahameng ho thusa hose ho boloka liphello tse ntle tsa tšebeliso libakeng tse phahameng tsa mocheso lehlabula, ho fana ka litiiso tse matla bakeng sa ts'ebetso e tloaelehileng ea mehaho.
4. Boenjiniere ba tšireletso ea tikoloho: Li-hose tsa rabara tsa EPDM le tsona li phetha karolo ea bohlokoa ho boenjiniere ba tšireletso ea tikoloho. Li sebelisoa haholo ho hloekisa metsi a litšila a indasteri, ho hloekisa likhoerekhoere le mekhoa ea ho ntša metsi, 'me li ka mamella mecha ea litaba e senyang le mocheso o phahameng ho netefatsa ts'ebetso e tsitsitseng ea lisebelisoa tsa ts'ireletso ea tikoloho.
5. Temo: Lefapheng la temo,Lithapo tsa rabara tsa EPDMhangata li sebelisoa mekhoeng ea ho nosetsa masimong, mekhoa ea ho fafatsa temo, lipalangoang tsa manyolo a temo, joalo-joalo. Lintho tsa eona tse khahlanong le botsofali le li-ultraviolet li etsa hore hose e sebelisoe nako e telele libakeng tse ka ntle, e fana ka tšehetso e matla bakeng sa tlhahiso ea temo.
Ka kakaretso,Hose ea rabara ea EPDMe bonts'itse matla a ts'ebeliso e matla liindastering tse ngata ka ts'ebetso ea eona e ntle haholo le likarolo tse pharaletseng tsa ts'ebeliso. Ka tsoelopele e tsoelang pele le kholo eaZebungTheknoloji, likarolo tsa ts'ebetso le ts'ebeliso eaHose ea rabara ea EPDMe tla atolosoa le ho ntlafatsoa ho ea pele, ho fana ka tharollo ea boleng bo holimo le e tšepahalang bakeng sa liindasteri tse ling.
