Izimpawu zezimoto zidlala indima ebalulekile ekuqinisekiseni ukusebenza kahle nokusebenza kwezimoto. Lezi zimpawu zivezwa yizici ezahlukahlukene zezemvelo, kufaka phakathi amazinga okushisa aphezulu, umswakama, namakhemikhali. Ukuthuthukisa ukusebenza kwabo nokuqina kwabo, abakhiqizi bezimoto baphendukela kokuqukethwe okusha okubizwa nge-ethylene propylene diene monomer (i-EPDM). Lo mbhalo uhlola izinzuzo zokusebenzisa izimpawu ze-EPDM embonini yezimoto futhi zivelele ukuthi ziqinisa kanjani ubuhle kulo mkhakha.
Izimpawu ze-EPDM zinikeza izinzuzo eziningi ngaphezu kwezinto zendabuko zendabuko. Okokuqala, babonisa ukumelana okuhlukile kokugula kwezulu nokuguga, kubenza bahlale isikhathi eside ezimeni ezinzima. Lokhu kuphila isikhathi eside kuqinisekisa ukuthi izimoto zigcina ubuqotho babo bokubekwa uphawu kwezikhathi ezeluliwe, kunciphisa isidingo sokufakwa kabusha kwezidingo. Okwesibili, izimpawu ze-EPDM zinokumelana kahle nokushisa okushisa ngokweqile, kubenza balungele ukusetshenziswa kuzo zombili izimo zezulu ezishisayo nezibandayo. Le mpahla ivimbela ukuguquguquka noma ukuqhekeka kwezimpawu zazo, ukuqinisekisa ukusebenza kahle kunoma yisiphi isimo sezulu.
Imboni yezimoto ikhula ngokwengeziwe uphawu lwe-EPDM ngenxa yokusebenza kwayo kanye nokuthembekile. Lezi zimpawu zithola izinhlelo zokusebenza ezingxenyeni ezahlukahlukene zezimoto, kufaka phakathi iminyango, amawindi, ama-sunroofs, ama-hoods, amabhodlela ezinhlamvu, nezindawo zenjini. Izimpawu ze-EPDM zinikeza ukumelana okuhleliwe okuhleliwe, kuqinisekisa ukuthi kufanelekile futhi okuphephile kulezi zinto. Lokhu, nakho, kuyasiza ekunciphiseni umsindo, ukudlidliza, kanye nokhahlo (NVH) amazinga, ukuthuthukisa isipiliyoni sokushayela jikelele kumakhasimende.
Ekuphetheni, ukusetshenziswa kwezimpawu ze-EPDM embonini yezimoto kunikeza izinzuzo eziningi, kufaka phakathi ukuqina okuthuthukile, ukumelana nokushisa okuthe xaxa, kanye namazinga we-NVH athuthukisiwe. Njengoba abakhiqizi bezimoto belwela ubuhle nokusebenza, izimpawu ze-EPDM zifakazela ukuthi ziguqulwa umdlalo, zigcizelela ukuzibophezela kwazo ekuletheni izimoto eziseqophelweni eliphezulu kubathengi.
Izinzuzo ze-Ethylene Propellene Diene Monomer (EPDM)
Izimpawu ze-Ethylene Propellene Dieen Monomer (EPDM) zinikeza izinzuzo eziningi ezimbonini ezahlukahlukene. Lezi zindawo eziguquguqukayo nezihlala isikhathi eside zisetshenziswa kabanzi kwimikhakha yezimoto, yokwakha, kanye nokwakha. Izimpawu ze-EPDM zenziwa ngezinto zokwenziwa zenjoloba ezibonisa ukumelana kahle ne-isimo sezulu, i-ozone, imisebe ye-UV, namazinga okushisa aphezulu. Lo mbhalo uzohlola izinzuzo zezimpawu ze-EPDM ngokuningiliziwe.
Enye yezinzuzo ezisemqoka zezimpawu ze-EPDM ukumelana kwazo okuyingqayizivele ezintweni zezemvelo. Noma ngabe kuwukuchayeka elangeni, imvula, noma amazinga okushisa aphezulu, izimpawu ze-EPDM zigcina ubuqotho babo nokusebenza kwabo. Lokhu kubenza balungele izinhlelo zokusebenza zangaphandle ezinjenge-apotive WeasethermerSpip, ukubekwa uphawu kwewindows, nezinhlelo zokuphahla. Ama-Seals e-EPDM abuye abuse ukumelana kahle namakhemikhali, abenze afanelekele ukusetshenziswa ezimbonini lapho kuvezwa khona izinto ezahlukahlukene kuvamile.
Izimpawu ze-EPDM zaziwa ngokuqina kwazo okuphezulu. Lezi zimpawu zinempilo yenkonzo ende futhi zikwazi ukumelana nokusebenzisa okuphindaphindwayo ngaphandle kokuwohloka. Amandla abo okugcina ukwakheka kwawo kanye nokubekwa uphawu ngesikhathi ngokuhamba kwesikhathi kubenza bathembeke kakhulu kwizicelo ezibucayi. Izimpawu ze-EPDM nazo zimelana nesethi yokuncintisana, okusho ukuthi zingakwazi ukuklebhula emuva esimweni sazo sokuqala ngemuva kokucindezelwa. Lesi sici siqinisekisa uphawu oluqinile nolusebenzayo, ukuvimbela ukuvuza kanye nokuqinisekisa ukusebenza kahle.
Enye inzuzo ebalulekile yezimpawu ze-EPDM yizindawo zazo ezinhle kakhulu zokufakelwa. Lezi zimpawu zinikeza ukufakwa okuphezulu okushisayo nokuzwakala okuzwakalayo, okwenza kube yinto elungele ukusetshenziswa ezinhlelweni ze-HVAC, ukufakwa ngogesi, kanye nemishini. Izikhala ze-EPDM zisiza ukuvikela ukudluliswa kokushisa, ukunciphisa ukusetshenziswa kwamandla kanye nokwenza ngcono ukusebenza kahle. Ngaphezu kwalokho, izakhiwo zazo zokufakwa okuzwakalayo zisiza ukunciphisa ukuhanjiswa komsindo, ukudala imvelo ethe xaxa futhi ethule.
Izimpawu ze-EPDM nazo zivumelana nezimo kakhulu, zizivumele zivumelane nezindawo ezingajwayelekile futhi zinikeze uphawu oluqinile. Ukuguquguquka kwabo kubenza bakulula ukufaka futhi baqinisekise ukuthi kufinyeleleke okuphephile, ngisho nasezinhlotsheni eziyinselele. Izimpawu ze-EPDM zingenziwa ngokwezifiso zokwakheka okukhethekile nosayizi, zibenze baguquguquke ngezidingo ezahlukahlukene zokubekwa uphawu.
Ukusetshenziswa kwezimpawu ze-EPDM embonini yezimoto
Izimpawu ze-EPDM, ezaziwa nangokuthi njenge-ethylene propylene Dieen Monomer Seals, zisetshenziswa kabanzi embonini yezimoto. Lezi zimpawu zenziwa ngengxenye yerabha ye-zokwenziwa enikeza ukumelana okuhle kakhulu ekushiseni, ozone, kanye nesimo sezulu. Zivame ukusetshenziswa ezinhlelweni ezahlukahlukene, kufaka phakathi izimpawu zomnyango kanye nezindawo zewindi, ama-gaskets enjini, kanye nokuxhumeka kwe-hose.
Enye yezinzuzo eziphambili zezimpawu ze-EPDM amandla abo okumelana namazinga okushisa aphezulu. Bangakwazi ukubhekana namazinga okushisa aphezulu futhi aphansi ngaphandle kokulahlekelwa yi-elasticity yawo noma ukuba aphuze. Lokhu kubenza balungele izinhlelo zokusebenza zezimoto lapho kungenzeka khona izimpawu zezulu ezinokhahlo noma amazinga okushisa enjini okwedlulele.
Ama-Seals e-EPDM nawo anokumelana kahle namakhemikhali namafutha, abenze balungele ukusetshenziswa embonini yezimoto. Bangakwazi ukubeka kahle uketshezi lwenjini, kuvimbela ukuvuza kanye nokuqinisekisa ukusebenza kahle. Ngaphezu kwalokho, ukumelana kwabo nemisebe ye-Ozone ne-UV kuyasiza ukwandisa isikhathi sabo sokuphila, kubenze kube yindlela ephumelelayo yabathengisi.
Enye inzuzo ebalulekile yezimpawu ze-EPDM ukuqina kwazo. Lezi zimpawu zinempilo yenkonzo ende futhi zikwazi ukubekezelela ukugqoka nokuklebhula, zizenze zilungele ukufuna izicelo zezimoto. Bangakwazi ukubeka kahle izingxenye ezahlukahlukene, ukuvimbela uthuli, amanzi, nezinye izinto zokungcola ukuthi zingangeni ezindaweni ezibucayi. Lokhu kusiza ukugcina ukusebenza okuphelele kanye nokusebenza kahle kwemoto.
Ngaphezu kwalokho, izimpawu ze-EPDM zinikeza izakhiwo ezinhle kakhulu zokubopha, ziqinisekisa uphawu oluqinile nolunokwethenjelwa. Lokhu kubalulekile embonini yezimoto, lapho ukuvuza okuncane kakhulu kungaholela ezindabeni ezibalulekile. Noma ngabe kuvimbela iminyango namafasitela ukuvikela ukungena kwamanzi noma ukuqinisekisa ukuxhumana okufanele enjini, izimpawu ze-EPDM zidlala indima ebalulekile ekugcineni ubuqotho bezinhlelo zezimoto.
Ukugcina
Izimpawu ze-EPDM zizuzisa kakhulu ngenxa yokumelana kwazo ezicini zemvelo, ukuqina, impahla yokufakelwa kanye nokuvumelana nezimo. Banikeza ukusebenza okuthembekile futhi okuhlala isikhathi eside ezimbonini ezinjengokwezimoto, ukwakhiwa kanye nokwakha. Izimpawu ze-EPDM ziyindlela enhle kakhulu yokufaka uphawu kwamawindi, ophahleni, imishini, nezinye izinhlelo, ngoba zingamelana nezimo ezinzima futhi zilondoloze izakhiwo zazo zokubopha futhi zigcine izakhiwo zazo zokubopha. Embonini yezimoto, izimpawu ze-EPDM zisetshenziswa kakhulu ngoba zingamelana namazinga okushisa aphezulu, zimelane namakhemikhali namafutha, futhi zinikeze izakhiwo ezinhle kakhulu zokubopha. Banikela ekusebenzeni okuphelele kanye nokwethenjwa kwezimoto ngokubopha iminyango, amawindi, izingxenye zenjini, kanye nokuxhumana kwe-hose. Izimpawu ze-EPDM zithathwa njengengxenye ebalulekile embonini yezimoto.
