izindaba

Ingaphakathi likanokusho, ama-hood acwebezelayo, ukuduma okumangazayo…konke kubonisa ukuzikhukhumeza kwezimoto zezemidlalo ezinkulu, ezibonakala zikude kakhulu nokuphila kwabantu abavamile, kodwa uyazi? Eqinisweni, ingaphakathi nama-hood alezi zimoto zenziwe ngemikhiqizo ye-fiberglass.

Ngaphezu kwezimoto ezisezingeni eliphezulu, abantu abavamile bashayela izimoto namaloli athutha izimpahla, zonke ezenziwe ngefayibha yengilazi. Kungashiwo ukuthi ukusebenza kwefayibha yengilazi kungandiswa unomphela.

Njengamanje, izinto ezihlanganisiwe zezingxenye zezimoto eziqiniswe ngefayibha yengilazi zingahlukaniswa zibe izinhlobo ezimbili: i-thermoplastic kanye ne-thermosetting. Izinqubo zokukhiqiza zalezi zibili zihlukile, futhi ukusetshenziswa kwazo kuhlukile. Imikhiqizo yefayibha yengilazi ye-thermosetting ye-LFT isetshenziselwa kakhulu izingxenye zangaphakathi zezimoto, njengezibiyeli zephaneli yezinsimbi, amabhokisi amathayi asele, izibiyeli zangaphambili kanye nezinye izingxenye zohlaka olungezona okuzenzakalelayo; imikhiqizo ye-thermoset SMC fiberglass isetshenziselwa kakhulu izimbobo zezimoto, amabhampa, kanye nezihlukanisi zamathangi kaphethiloli. Izimbozo zokushisa nezinye izingxenye zesakhiwo sezimoto.
Ngokuthuthuka kwemboni yezimoto kanye nokukhuthazwa kokulondolozwa kwamandla kanye nemibono yokuvikela imvelo, izimoto ezilula seziyisitayela esivamile. Ukusetshenziswa kukaphethiloli wemoto kuncike kakhulu ekushintsheni kwenjini kanye nesisindo sayo yonke imoto. Ngenxa yokugcina ikhwalithi iyonke, ukusebenza kanye nezindleko zemoto, ukunciphisa isisindo semoto kungakhuphula ngempumelelo amandla okukhipha kanye nokuphatha, kunciphise ukusetshenziswa kukaphethiloli, futhi kunciphise ukukhishwa komoya ophumayo. Izifundo zikhombisile ukuthi ngokunciphisa ngakunye okungu-10% kwesisindo semoto, ukusetshenziswa kukaphethiloli kungancishiswa ngo-6-8%. Ukufaka esikhundleni sensimbi yendabuko ngefayibha yengilazi kunganciphisa kakhulu isisindo semoto.

Imikhiqizo ye-SMC iyingxenye ebalulekile yezingxenye zezimoto. Indlela yokunciphisa isisindo sezimoto ngokuthuthukisa ukusebenza kwazo yinkinga ephuthumayo okufanele abakhiqizi bezimoto bayixazulule.
Njengamanje, indlela eqashelwa kakhulu embonini ukufaka ama-filler endabuko ngama-glass beads angenalutho, ngaleyo ndlela kuncishiswe ubuningi beshidi, ukuze kufezwe umphumela wokunciphisa isisindo semoto. Kodwa inkinga ebangelwa yilokhu ukuthi izakhiwo zemishini zezinto nazo ziyancipha. Ngakho-ke, ukuze kuqinisekiswe izakhiwo zemishini ngaphansi kwezimo eziphansi kobuningi, imicu yengilazi ingasetshenziswa ukuhlinzeka ngezimo zemishini eziphezulu. Imikhiqizo ye-SMC okukhulunywe ngayo ngenhla yakhiwe nge-glass fiber, i-filler kanye ne-resin.
Imikhiqizo yefayibha yengilazi ye-SMC enamandla aphezulu kanye nezakhiwo zobuso. Umkhiqizo ungahlangabezana nezidingo zezakhiwo zomshini kanye nezakhiwo zobuso zezinga le-A ngesikhathi esisodwa, futhi ufanelekela ukukhiqizwa kwezingxenye zokubukeka kwezimoto kanye nezingxenye zesakhiwo. Uma kuqhathaniswa nabancintisana embonini ngaphansi kwezimo ezifanayo, ukusebenza komshini sekukonke kukhuphuke ngo-20%, okunikeza ikhambi lenkinga yokuwohloka kokusebenza komshini kwe-SMC okuphansi.
Njengalezo zimoto zezemidlalo ezinkulu ezifiselekayo, izidingo zamandla nokubukeka ziphakeme kakhulu kunezimoto ezivamile, ikakhulukazi ngokubukeka nokushelela. I-SMC isebenzisa i-glass fiber 456 njengohlobo olusha lomkhiqizo we-glass fiber wezingxenye zezimoto, olungahlangabezana nobuso be-A-level yekhasimende, okungukuthi, izidingo zobuso besibuko, futhi ukukhanya kwayo kwanele ukuhambisana nokubekwa kwezimoto ezinkulu.

Ngaphezu kwemikhiqizo ye-SMC, izinto ze-thermoplastic eziqiniswe ngefayibha yengilazi nazo zingadlala indima ebalulekile emkhakheni wokufaka insimbi esikhundleni sepulasitiki ezimotweni. Intambo ye-LFT esebenza kahle kakhulu engu-362H isetshenziswa kakhulu ezingxenyeni zezimoto njengezibuko ezingemuva, izembozo ezingangeni msindo, amabakaki ephaneli yezinsimbi, njll.
Ubuchwepheshe be-LFT bunezidingo eziphezulu zokucutshungulwa kwentambo, ikakhulukazi ukumelana nokuguguleka kwentambo. Uboya ngekhilogremu engu-362H buphansi kakhulu. UDkt. Fan Jiashu we-Product R&D Center ukuqinisekisile lokhu ngokuqhathanisa okulingayo. Lapho ebeka umswakama ku-50%, uboya ngekhilogremu engu-362H buphansi kakhulu kunobomkhiqizo wokuqhathanisa; lapho umswakama ukhuphuka ufike ku-75%, uboya bayo yonke imikhiqizo buyanda, okunqunywa yizici ze-ejenti yokulinganisa yentambo uqobo. Kodwa okumangalisayo ukuthi lapho umswakama ungama-75%, uboya be-362H busephansi kunobeqembu lokulawula, okubonisa ukumelana okuhle kakhulu kokuguguleka kwe-362H.
Akukhona lokho kuphela, izakhiwo zemishini ze-362H nazo zinamandla aphezulu kanye nokuqina okuphezulu. Ngayo, imoto izomelana kakhulu nokuphahlazeka lapho kwenzeka umthelela omkhulu. Ngeke "ibe buthakathaka" njengensimbi, futhi ngeke "ilimale kalula". Lokhu kufana nobuso be-362H. Ukwelashwa kwe-ejenti yosayizi oyingqayizivele akuhlukaniseki. Ukuthuthukiswa koboya obuphezulu bokukhiqiza kanye nokusebenza okuphezulu kwe-LFT-enhanced direct warn ye-PP 362H kuthuthukisa kakhulu uhlelo lomkhiqizo woboya obuqondile be-LFT. Ukusabalala kwayo okuphezulu kanye nokugcotshwa kwayo okuphezulu kuhlangabezana nezidingo zamakhasimende zokucutshungulwa kalula.
