Izinto zangaphakathi zikanokusho, izigqoko ezicwebezelayo, ukubhonga okushaqisayo...konke kubonisa ukuzikhukhumeza kwezimoto zezemidlalo eziphambili, ezibonakala zikude nempilo yabantu abavamile, kodwa ingabe uyazi?Eqinisweni, ingaphakathi nama-hoods alezi zimoto zenziwe ngemikhiqizo ye-fiberglass.
Ngaphandle kwezimoto ezisezingeni eliphezulu, abantu abaningi abajwayelekile bashayela izimoto namaloli athutha impahla, wonke enziwe nge-glass fiber.Kungashiwo ukuthi ukusebenza kwesicelo se-glass fiber kunganwetshwa unomphela.
Njengamanje, izinto eziyinhlanganisela yezingxenye zezimoto eziqiniswe ngengilazi zingahlukaniswa zibe izinhlobo ezimbili: i-thermoplastic ne-thermosetting.Izinqubo zokukhiqiza kokubili zihlukile, futhi ukusetshenziswa nakho kuhlukile.Imikhiqizo ye-fiber yengilazi ye-Thermosetting ye-LFT isetshenziselwa ikakhulukazi izingxenye zangaphakathi zezimoto, njengabakaki bephaneli yezinsimbi, amabhokisi angamasondo ayisipele, abakaki abangaphambili nezinye izingxenye zozimele ezingezona ezizenzakalelayo;Imikhiqizo ye-thermoset SMC fiberglass isetshenziselwa ikakhulukazi ama-hoods ezimoto, amabhampa, nezihlukanisi zamathangi kaphethiloli.Amakhava ashisayo nezinye izingxenye zesakhiwo sezimoto.
Ngokuthuthuka kwemboni yezimoto kanye nokugqugquzelwa kokugcinwa kwamandla kanye nemiqondo yokuvikela imvelo, izimoto ezingasindi seziphenduke inkambiso evamile.Ukusetshenziswa kukaphethiloli wemoto kuncike kakhulu ekugudluzweni kwenjini kanye nesisindo esiphelele semoto.Ngokwesisekelo sokugcina ikhwalithi iyonke, ukusebenza kanye nezindleko zemoto, ukunciphisa isisindo semoto kungakhuphula ngempumelelo amandla okukhiphayo nokubamba, ukunciphisa ukusetshenziswa kukaphethiloli, nokunciphisa ukukhishwa kwe-exhaust.Ucwaningo luye lwabonisa ukuthi njalo ngo-10% ukunciphisa isisindo semoto, ukusetshenziswa kukaphethiloli kungancishiswa ngo-6-8%.Ukushintsha insimbi yendabuko nge-glass fiber kunganciphisa kakhulu isisindo semoto.
Imikhiqizo ye-SMC iyingxenye ebalulekile yezingxenye zezimoto.Indlela yokunciphisa isisindo sezimoto ngokuthuthukisa ukusebenza kwazo kuyinkinga ephuthumayo okufanele ixazululwe abakhiqizi bezimoto.
Njengamanje, indlela eyaziwa kakhulu embonini iwukuba esikhundleni sokugcwaliswa kwendabuko ngobuhlalu bengilazi obungenalutho, ngaleyo ndlela kunciphise ukuminyana kweshidi, ukufeza umphumela wokunciphisa isisindo semoto.Kodwa inkinga eyilethwa yilokhu ukuthi izakhiwo zemishini zezinto nazo ziyancipha.Ngakho-ke, ukuze kuqinisekiswe izakhiwo zemishini ngaphansi kwezimo eziphansi, imicu yengilazi ingasetshenziswa ukuhlinzeka ngezimo eziphezulu zemishini.Imikhiqizo ye-SMC eshiwo ngenhla yenziwe nge-glass fiber, filler kanye ne-resin.
Imikhiqizo ye-Glass fiber ye-SMC enamandla aphezulu kanye nezakhiwo ezingaphezulu.Umkhiqizo ungahlangabezana nezidingo zezakhiwo zemishini kanye nezindawo ezingaphezulu kwezinga le-A ngesikhathi esifanayo, futhi ulungele ukukhiqizwa kwezingxenye zokubukeka kwemoto kanye nezingxenye zesakhiwo.Uma kuqhathaniswa nezimbangi zezimboni ngaphansi kwezimo ezifanayo, ukusebenza kwemishini sekukonke kukhuphuke ngo-20%, okunikeza isisombululo senkinga yokuwohloka kokusebenza kwemishini ye-SMC ephansi.
Njengalezo zimoto ezinkulu zezemidlalo ezinomona, izidingo zamandla nokubukeka ziphakeme kakhulu kunezimoto ezijwayelekile, ikakhulukazi ukubukeka nokushelela.I-SMC isebenzisa i-glass fiber 456 njengohlobo olusha lomkhiqizo we-glass fiber ezingxenyeni zezimoto, ezingahlangabezana nezinga le-A lekhasimende, okungukuthi, izimfuneko zesibuko, futhi ukukhanya kwayo kwanele ukuhambisana nokuma kwezimoto ezinkulu.
Ngaphezu kwemikhiqizo ye-SMC, izinto zokwakha ze-thermoplastic eziqiniswe ngengilazi nazo zingadlala indima ebalulekile emkhakheni wokushintsha insimbi ngepulasitiki ezimotweni.Intambo ye-LFT esebenza kahle kakhulu engu-362H isetshenziswa kakhulu ezingxenyeni zemoto ezifana nezibuko ezibuka ngemuva, amakhava angenamsindo, abakaki bephaneli yezinsimbi, njll.
Ubuchwepheshe be-LFT bunezidingo eziphezulu zokucutshungulwa kwentambo, ikakhulukazi ukumelana nokugqokwa kwentambo.Uboya bezinwele ngekhilogremu engu-362H buphansi kakhulu.UDkt. Fan Jiashu Wesikhungo Se-R&D Yomkhiqizo ukuqinisekisile lokhu ngokuqhathanisa kokuhlola.Lapho ebeka umswakama ku-50%, izinwele ze-kilogram ze-362H ziphansi kakhulu kunomkhiqizo wokuqhathanisa;lapho umswakama ukhuphuka ufike ku-75%, izinwele zezinwele zayo yonke imikhiqizo ziyanda, okunqunywa izici ze-agent yokulinganisa yentambo ngokwayo.Kodwa okumangalisayo ukuthi uma umswakama ungama-75%, izinwele ze-362H zisephansi kuneqembu lokulawula, okubonisa ukumelana okuhle kakhulu kwe-abrasion ye-362H.
Akukhona lokho kuphela, izakhiwo zemishini ye-362H nazo zingamandla aphezulu kanye nokuqina okuphezulu.Ngayo, imoto izomelana kakhulu nokuphahlazeka lapho kwenzeka umthelela omkhulu.Ngeke ibe "brittle" njengensimbi, futhi ngeke "ilimale" kalula.Lokhu kuyafana nobuso buka-362H.Ukwelashwa kwe-ejenti yokulinganisa okuyingqayizivele akunakuhlukaniswa.Ukuthuthukiswa kokwenziwa okuphezulu kanye nentambo eqondile ethuthukisiwe ye-LFT ethuthukisiwe ye-PP 362H ngokuqhubekayo kuthuthukisa uhlelo lomkhiqizo lwentambo eqondile ye-LFT.Ukuhlakazeka kwayo okuphezulu kanye nokugcotshwa okuphezulu kuhlangabezana nezidingo zekhasimende zokuqhubekela phambili.
