Ama-Fluoroelastomers aqhamuke njengoshintsho embonini yezimoto nemishini, enikeza ukuguquguquka okungenakuqhathaniswa ekusetshenzisweni okuhlukahlukene. Ngokumelana kwawo namakhemikhali okukhethekile, ukuzinza kwezinga lokushisa eliphezulu, kanye nezakhiwo ezisezingeni eliphezulu zemishini, lawa ma-elastomer asephenduke indawo yokukhetha yokunikeza amandla imishini yezimboni. Emkhakheni wezimoto, ama-fluoroelastomers afakazele ukuqina kwawo ngokuqinisekisa ukusebenza okuthembekile ezinhlelweni ezibucayi ezifana namasistimu kaphethiloli, ama-seal enjini, nama-gaskets. Ukumelana kwazo nezinto zokubasa, uwoyela, namanye amakhemikhali anolaka kuzenza zilungele ukugcina ubuqotho bezingxenye zezimoto ezindaweni ezidinga kakhulu. Ngaphezu kwalokho, ikhono lama-fluoroelastomers lokumelana namazinga okushisa aphakeme kanye nezimo zezulu ezimbi liwenze abaluleke kakhulu ekusetshenzisweni kwemishini. Ukusuka kuma-seal nama-O-rings kuye kuma-diaphragm nama-gaskets, ama-fluoroelastomers adlala indima ebalulekile ekuqinisekiseni ukusebenza kahle nokuthembekile kwemishini ehlukahlukene. Kulesi sihloko, sizocubungula ukusebenzisana kwezinto ezihlukahlukene kwama-fluoroelastomers kukho kokubili izinhlelo zokusebenza zezimoto nemishini, sihlole izakhiwo zazo ezihlukile kanye nezinzuzo ezizinikeza abakhiqizi nabasebenzisi bokugcina ngokufanayo.
Ukuhlukahluka kwe-Fluoroelastomers kuzinhlelo zokusebenza zezimoto
I-Fluoroelastomers, eyaziwa nangokuthi i-FKM, iwuhlobo lwerabha yokwenziwa enikeza ukuguquguquka okukhethekile ezinhlelweni zezimoto. Ngenhlanganisela yawo eyingqayizivele yokumelana nokushisa okuphezulu, ukuhambisana kwamakhemikhali, nokuqina, ama-fluoroelastomers abe yingxenye ebalulekile ezinhlelweni ezihlukahlukene zezimoto.
Enye yezinzuzo eziyinhloko zama-fluoroelastomers amandla awo okumelana namazinga okushisa aphezulu. Lezi zinsiza zingasebenza kahle ezindaweni ezisukela ku -40°C kuya ku-250°C, zizenze zilungele ukusetshenziswa lapho ukuguquka kwezinga lokushisa kuvame, njengezigxivizo zenjini nama-gaskets. Ukumelana kwazo nokushisa okuhle kakhulu kuqinisekisa ukuthi ama-seal agcina ubuqotho bawo, avimbele noma yikuphi ukuvuza noma ukwehluleka okungaholela ekulungiseni okubizayo.
Ngaphezu kokumelana nezinga lokushisa, ama-fluoroelastomers nawo abonisa ukuhambisana kwamakhemikhali okuhlukile. Angakwazi ukumelana nokuchayeka kumafutha, uwoyela, izincibilikisi, noketshezi oluhlukahlukene lwezimoto ngaphandle kokuwohloka noma ukulahlekelwa izici zazo zokuvala. Lokhu kumelana namakhemikhali kubalulekile ekusebenzeni kwezimoto, lapho ukuchayeka ezinto ezonakalisayo kuvame. Ngokusebenzisa ama-fluoroelastomers, abakhiqizi bangaqinisekisa ukuthi izimoto zabo zihlala zingavuzi futhi zisebenza ngisho nasezimeni ezinzima kakhulu.
Ukuqina ngesinye isici esibalulekile sama-fluoroelastomers. Lezi zinto zinezici ezinhle kakhulu zemishini, kufaka phakathi amandla aphezulu okudonsa kanye nokumelana nokukhala. Lokhu kubenza baqine kakhulu ekugugekeni nasekudabukeni, okuqinisekisa ukusebenza okuhlala isikhathi eside ekufuneni izicelo zezimoto. Kungakhathaliseki ukuthi isetshenziswa ezingxenyeni zenjini, amasistimu kaphethiloli, noma ama-transmission seal, ama-fluoroelastomers ahlinzeka ngezixazululo ezithembekile zokuvala ezingamelana nobunzima bokusetshenziswa kwansuku zonke.
Ukuguquguquka kwama-fluoroelastomers kudlulela ngalé kwezakhiwo zawo zokusebenza. Lezi zinto zibuye zibumbeke kakhulu, okuvumela abakhiqizi ukuthi bakhe izimo eziyinkimbinkimbi nemiklamo ukuze ivumelane nezidingo ezithile zezimoto. Kungakhathaliseki ukuthi i-gasket yangokwezifiso noma uphawu olunembayo, ama-fluoroelastomers angabunjwa ukuze abe nokucaciswa okunembile, okuqinisekisa ukulingana okuphelele nokusebenza okuphelele.
Ukuhlukahluka kwe-Fluoroelastomers Kuzicelo Zomshini
I-Fluoroelastomers iyimpahla eguquguqukayo kakhulu ethola ukusetshenziswa okubanzi ezimbonini zemishini ehlukahlukene. Ngezakhiwo zabo ezihlukile kanye nekhono lokumelana nezimo ezimbi kakhulu, ama-fluoroelastomers asebaluleke kakhulu ekuqinisekiseni ukwethembeka nokuphila isikhathi eside kwezingxenye zemishini.
Enye yezinzuzo ezibalulekile zama-fluoroelastomers ukumelana kwawo okuhle kakhulu namazinga okushisa aphezulu. Ukusetshenziswa kwemishini kuvame ukubandakanya ukuchayeka emazingeni okushisa aphakeme, futhi ama-fluoroelastomers angagcina izakhiwo zawo eziwumshini ngisho nalapho kushisa kakhulu. Lesi sakhiwo sizenza zilungele ukusetshenziswa kuma-gaskets, seal, nama-O-rings, lapho zingavimbela khona ukuvuza futhi ziqinisekise ubuqotho bemishini.
Ngaphezu kokumelana kwawo nezinga lokushisa eliphezulu, ama-fluoroelastomers nawo akhombisa ukumelana namakhemikhali okuhlukile. Angakwazi ukumelana nokuchayeka ezinhlobonhlobo zamakhemikhali, okuhlanganisa izinto zokubasa, uwoyela, izinyibilikisi, nama-asidi. Lokhu kubenza bafanelekele ukusetshenziswa emishinini lapho ukuthintana nezinto ezonakalisayo kuvame. Ngokusebenzisa ama-fluoroelastomers, abakhiqizi bangathuthukisa ukuqina nokuthembeka kwemishini yabo, behlise ubungozi bokwehluleka kwengxenye kanye nokulungiswa okumba eqolo.
Esinye isici esibalulekile sama-fluoroelastomers ukumelana kwawo nesethi yokucindezela. Izingxenye zemishini zivame ukubhekana nokucindezela okukhulu nokucindezelwa, okungaholela ekuguquguqukeni nasekulahlekelweni kokusebenza ngokuhamba kwesikhathi. Kodwa-ke, ama-fluoroelastomers anamandla okugcina ukwakheka kwawo nokunwebeka ngisho nangaphansi kokucindezelwa isikhathi eside. Lesi sakhiwo siqinisekisa ukuthi imishini isebenza ngokushelela nangempumelelo, ngaphandle kokulahlekelwa ekusebenzeni noma ukwanda kokusetshenziswa kwamandla.
Ngaphezu kwalokho, ama-fluoroelastomers anikeza ukumelana okuhle kakhulu ne-ozone nesimo sezulu, okuwenza afanelekele ukusetshenziswa kwemishini yangaphandle. Bangakwazi ukumelana nokuchayeka emisebeni ye-UV, amazinga okushisa aphakeme, nezimo zezulu ezinzima, ngaphandle kokuwohloka noma ukulahlekelwa izici zabo ezibonakalayo. Lokhu kumelana nezinto zemvelo kuqinisekisa ukuphila isikhathi eside nokuthembeka kwemishini, ngisho nasezilungiselelweni zangaphandle eziyinselele.
Isiphetho
Ama-Fluoroelastomers anikezela ngezinzuzo ezahlukahlukene ekusetshenzisweni kwezimoto nemishini. Angakwazi ukumelana namazinga okushisa aphakeme, amelane namakhemikhali, anikeze ukuqina, futhi anikeze ukuguquguquka kokuklama. Lokhu kubenza babaluleke embonini yezimoto, ukuqinisekisa ukwethembeka nokuphila isikhathi eside kwezimoto. Embonini yemishini, ama-fluoroelastomers akhethwa ngenxa yokumelana kwawo nezinga lokushisa eliphezulu, ukumelana namakhemikhali, ukumelana nesethi yokucindezela, nokumelana ne-ozone nesimo sezulu. Ngokuhlanganisa ama-fluoroelastomers ezingxenyeni zemishini, abakhiqizi bangaqinisekisa ukusebenza kahle, ukuphila isikhathi eside, nokuthembeka, okuzuzisa imboni kanye nabasebenzisi bokugcina.
