Ipulasitiki ye-polypropylene eqiniswe ngefayibha yengilazi ende ibhekisela ezintweni ezihlanganisiwe ze-polypropylene eziguquliwe ezinobude befayibha yengilazi obungu-10-25mm, ezakhiwe zibe isakhiwo esinezilinganiso ezintathu ngokusebenzisa ukubumba ngemijovo nezinye izinqubo, ezifushaniswe ngokuthi i-LGFPP. Ngenxa yokusebenza kwayo okuhle kakhulu, i-polypropylene eqiniswe ngefayibha yengilazi ende isetshenziswa kabanzi emkhakheni wezimoto.
Izici kanye nezinzuzo ze-polypropylene ende eqiniswe nge-fiber yengilazi
- Ukuqina okuhle kobukhulu
- Ukumelana nokukhathala okuhle kakhulu
- Ukusebenza okuncane kokunyakaza
- i-anisotropy encane, ukuguqulwa kwe-warpage okuphansi
- Izakhiwo ezinhle kakhulu zemishini, ikakhulukazi ukumelana nomthelela
- Ukugeleza okuhle, okufanelekela ukucutshungulwa komkhiqizo odongeni oluncane
I-polypropylene eqiniswe ngefayibha yengilazi ende engu-10 ~ 25mm (LGFPP) inamandla aphezulu, ukuqina, ukuqina, ukuzinza okulinganiselwe, kanye nokugoba okuphansi uma kuqhathaniswa ne-polypropylene eqiniswe ngefayibha yengilazi emfushane engu-4 ~ 7mm evamile. Ngaphezu kwalokho, izinto ze-polypropylene eqiniswe ngefayibha yengilazi ende ngeke zikhiqize ukugoba okukhulu noma ngabe zitholwa ekushiseni okuphezulu okungu-100 ℃, futhi zinokumelana okungcono kokugoba kune-polypropylene eqiniswe ngefayibha yengilazi emfushane.
Kumkhiqizo obunjiwe ngomjovo, imicu yengilazi ende ihlanganiswa ibe yisakhiwo senethiwekhi esinezinhlangothi ezintathu. Ngisho nangemva kokuba i-substrate ye-polypropylene isishisiwe, inethiwekhi ye-fiber yengilazi ende isakha i-skeleton ye-fiber yengilazi enamandla athile, kuyilapho i-fiber yengilazi emfushane ngokuvamile iba i-fiber engenamandla ngemva kokushiswa. Lesi simo sibangelwa ikakhulukazi ngoba isilinganiso sobude nobubanzi be-fiber yokuqinisa sinquma umphumela wokuqinisa. Ama-filler kanye nemicu yengilazi emfushane enesilinganiso sesici esibucayi esingaphansi kuka-100 ayinazo iziqiniseko, kuyilapho imicu yengilazi ende enesilinganiso sesici esibucayi esingaphezu kuka-100 idlala indima yokuqinisa.
Uma kuqhathaniswa nezinto zensimbi nezinto ezihlanganisiwe ze-thermosetting, ipulasitiki yefayibha yengilazi ende inobuningi obuphansi, futhi isisindo sengxenye efanayo singancishiswa ngo-20% kuya ku-50%. Ipulasitiki yefayibha yengilazi ende inganikeza abaklami ukuguquguquka okukhulu komklamo, njengezimo ezibunjwayo ezinezimo eziyinkimbinkimbi. Inani lezingxenye nezingxenye ezihlanganisiwe ezisetshenziswayo kusindisa izindleko zesikhunta (ngokuvamile, izindleko zesikhunta sepulasitiki yefayibha yengilazi ende zingaba ngu-20% wezindleko zesikhunta sokunyathela insimbi), futhi kunciphisa ukusetshenziswa kwamandla (ukusetshenziswa kwamandla okukhiqiza kwepulasitiki yefayibha yengilazi ende kungu-60% kuphela wemikhiqizo yensimbi. %~80%, 35%~50% yemikhiqizo ye-aluminium), okwenza kube lula inqubo yokuhlanganisa.
Ukusetshenziswa kwe-Long Glass Fiber Reinforced Polypropylene ezingxenyeni zezimoto
I-polypropylene eqiniswe ngefayibha ende isetshenziswa ohlakeni lomzimba wedeshibhodi yemoto, i-bracket yebhethri, i-module yangaphambili, ibhokisi lokulawula, uhlaka lokusekela isihlalo, i-placenta eyisipele, i-mudguard, ikhava ye-chassis, isithiyo somsindo, uhlaka lomnyango wangemuva, njll.
Imodyuli engaphambili: Kumamojula engaphambili ezimoto, kusetshenziswa izinto ze-LGFPP (okuqukethwe yi-LGF okungu-30%), ingahlanganisa izingxenye zensimbi zendabuko ezingaphezu kwe-10 ezifana nama-radiator, izipikha, ama-condenser, kanye nama-brackets zibe yi-whole; ayimelani nokugqwala kakhulu kunezingxenye zensimbi. Ubuningi buncane, isisindo sincishiswa cishe ngo-30%, futhi inezinga eliphakeme lenkululeko yokuklama. Ingaphinde isetshenziswe ngqo ngaphandle kokuhlunga nokucubungula; inciphisa izindleko zokukhiqiza futhi inezinzuzo ezisobala zokunciphisa izindleko.
Uhlaka lomzimba wephaneli yezinsimbi: Kwezinto zokwakha uhlaka lwephaneli yezinsimbi ezithambile, ukusebenzisa izinto ze-LGFPP kunamandla aphezulu, i-modulus ephezulu yokugoba, kanye nokugeleza okungcono kunezinto ze-PP ezigcwalisiwe. Ngaphansi kwamandla afanayo, ubukhulu bomklamo wephaneli yezinsimbi bungancishiswa ukuze kuncishiswe isisindo, Umphumela wokulahlekelwa isisindo ojwayelekile ungaba ngu-20%. Ngesikhathi esifanayo, i-bracket yephaneli yezinsimbi yendabuko enezingxenye eziningi ingathuthukiswa ibe yimojula eyodwa. Ngaphezu kwalokho, ukukhethwa kwezinto zomzimba womsele wangaphambili wokuncibilikisa kanye nohlaka oluphakathi lwedeshibhodi ngokuvamile kuyizinto ezifanayo nohlaka oluyinhloko lwedeshibhodi, olungathuthukisa kakhulu umphumela wokunciphisa isisindo.
Isihlalo esingemuva: Singathatha indawo yohlaka lwensimbi lwendabuko ukuze sifinyelele ukwehla kwesisindo okungu-20%, futhi sinenkululeko yokuklama enhle kakhulu kanye nokusebenza kahle kwemishini, kanye nezici ezifana nendawo yokuhlala eyandisiwe.
Ukubaluleka kokusetshenziswa kwe-polypropylene ende eqinisiwe yengilazi ensimini yezimoto
Ngokuphathelene nokushintshana kwezinto, imikhiqizo ye-polypropylene eqiniswe ngefayibha yengilazi ende inganciphisa isisindo kanye nezindleko ngesikhathi esifanayo. Esikhathini esidlule, izinto eziqiniswe ngefayibha yengilazi emfushane zathatha indawo yezinto zensimbi. Eminyakeni yamuva nje, ngokusetshenziswa nokuthuthukiswa kwezinto ezilula, izinto ze-polypropylene eqiniswe ngefayibha yengilazi ende ziye zathatha indawo kancane kancane yepulasitiki eqiniswe ngefayibha yengilazi emfushane ezingxenyeni eziningi zezimoto, okukhuthazwa kakhulu. Ucwaningo nokusetshenziswa kwezinto ze-LGFPP ezimotweni.
