Eminyakeni yamuva nje, ukusetshenziswa kwamapulasitiki ezimotweni kuye kwaqhubeka nokwanda.Njengamanje, ukusetshenziswa kwamapulasitiki ezimoto eJalimane, e-United States, eJapan nakwamanye amazwe sekufinyelele ku-10% kuya ku-15%, kanti amanye aze afinyelela ngaphezulu kwama-20%.Uma sibheka izinto ezisetshenziswa ezimotweni zanamuhla, kungakhathaliseki ukuthi izingxenye zokuhlobisa zangaphandle, izingxenye zokuhlobisa zangaphakathi, noma izingxenye ezisebenzayo nezakhiwo, isithunzi sokukhiqizwa kwepulasitiki singabonakala yonke indawo.Futhi ngokuthuthuka okuqhubekayo kobulukhuni bobunjiniyela bobunjiniyela, amandla, kanye nezakhiwo eziqinile, amafasitela epulasitiki, iminyango, amafreyimu ngisho nezimoto zonke zepulasitiki ziye zavela kancane kancane, futhi inqubo ye-plasticization yezimoto iyakhula ngesivinini.
Yiziphi izinzuzo zokusebenzisa ipulasitiki njengezinto zezimoto?
1.Ukubumba ipulasitiki kulula, okwenza kube lula kakhulu ukucubungula izingxenye ezinobunjwa obuyinkimbinkimbi.Isibonelo, lapho iphaneli yensimbi icutshungulwa ngamapuleti ensimbi, ngokuvamile kudingekile ukucubungula nokubumba izingxenye ezihlukahlukene, bese uzihlanganisa noma uzishise ngezixhumi, okudinga izinqubo eziningi.Ukusetshenziswa kwepulasitiki kungabunjwa ngesikhathi esisodwa, isikhathi sokucubungula sifushane, futhi ukunemba kuqinisekisiwe.
2. Inzuzo enkulu yokusebenzisa amapulasitiki ezintweni zezimoto ukunciphisa isisindo somzimba wemoto.I-Lightweight inhloso elandelwa imboni yezimoto, futhi amapulasitiki angabonisa amandla awo kulokhu.Ngokuvamile, amandla adonsela phansi epulasitiki angu-0.9 ~ 1.5, futhi amandla adonsela phansi athile ezinto ezihlanganisiwe ze-fiber ngeke adlule 2. Phakathi kwezinto zensimbi, amandla adonsela phansi ensimbi ye-A3 angu-7.6, ithusi yi-8.4, futhi i-aluminium ingu-2.7.Lokhu kwenza amapulasitiki abe yizinto ezithandwayo ezimotweni ezingasindi.
3. Izici zokuguga okunwebekayo zemikhiqizo yepulasitiki zimunca amandla amaningi okushayisana, zibe nomthelela omkhulu wokubhafa emithelelaneni eqinile, futhi zivikele izimoto nabagibeli.Ngakho-ke, amaphaneli ensimbi yepulasitiki namasondo okuqondisa asetshenziswa ezimotweni zanamuhla ukuze kuthuthukiswe umphumela wokugoba.Amabhampa angaphambili nangemuva kanye nama-trim strips enziwe ngezinto zepulasitiki ukunciphisa umthelela wezinto ezingaphandle kwemoto lapho nomsindo wemoto.Ngaphezu kwalokho, ipulasitiki nayo inomsebenzi wokumunca nokunciphisa ukudlidliza nomsindo, okungathuthukisa ukunethezeka kokugibela.
4. amapulasitiki angenziwa amapulasitiki anezakhiwo ezidingekayo ngokungeza ama-fillers ahlukene, ama-plasticizers kanye nama-hardeners ngokusho kokwakheka kwamapulasitiki, futhi amandla emishini kanye nokucubungula kanye nezakhiwo zokubumba zezinto zingashintshwa ukuze kuhlangabezane nezidingo zezingxenye ezahlukene emotweni. .Isibonelo, i-bumper kumele ibe namandla amakhulu, kuyilapho umcamelo ne-backrest kufanele yenziwe ngegwebu elithambile le-polyurethane.
5.Ipulasitiki inokumelana nokugqwala okuqinile futhi ngeke igle uma ilimele endaweni.Kodwa-ke, uma indawo kapende yonakele noma i-anti-corrosion ingenziwanga kahle ekukhiqizeni insimbi, kulula ukugqwala nokugqwala.Ukumelana nokugqwala kwamapulasitiki kuma-asidi, ama-alkali, nosawoti kukhulu kunokwamapuleti ensimbi.Uma amapulasitiki asetshenziswa njengezembozo zomzimba, afaneleka kakhulu ukusetshenziswa ezindaweni ezinokungcola okukhulu.
Ngokuvamile, amapulasitiki ezimoto athuthukile kusukela ezingxenyeni ezijwayelekile zokuhlobisa kuya ezingxenyeni zesakhiwo kanye nezingxenye zokusebenza;izinto zepulasitiki zezimoto ziyathuthuka zibheke ezintweni eziyinhlanganisela nama-alloys epulasitiki anamandla aphezulu, umthelela ongcono, nokugeleza okuphezulu kakhulu.Luselude ukhalo okusamele luhanjwe ngokukhangiswa kwezimoto zepulasitiki esikhathini esizayo.Akuyona nje kuphela indaba yokuphepha, kodwa futhi nezindaba ezifana nokuguga nokugaywa kabusha.Lokhu kudinga ukuthuthukiswa okwengeziwe kwezobuchwepheshe.
