Ipulasitiki ende yengilazi eqinisiwe ye-polypropylene ibhekisela ezintweni eziyinhlanganisela ye-polypropylene eguquliwe ene-glass fibre ubude obuyi-10-25mm, eyakhiwe yaba isakhiwo esinezinhlangothi ezintathu ngokubumba umjovo nezinye izinqubo, ezifushanisiwe njenge-LGFPP.Ngenxa yokusebenza kwayo okuhle kakhulu okubanzi, ingilazi ende eqiniswe nge-polypropylene isetshenziswa kabanzi emkhakheni wezimoto.
Izici nezinzuzo ze-fiber yengilazi ende eqiniswe i-polypropylene
- Ukuzinza okuhle kwe-dimensional
- Ukumelana nokukhathala okuhle kakhulu
- Ukusebenza kwe-creep encane
- I-anisotropy encane, i-warpage deformation ephansi
- Izakhiwo ezinhle kakhulu zemishini, ikakhulukazi ukumelana nomthelela
- I-fluidity enhle, ilungele ukucutshungulwa komkhiqizo onezindonga ezincane
I-10 ~ 25mm yengilazi ende ye-fiber reinforced polypropylene (LGFPP) inamandla aphakeme, ukuqina, ukuqina, ukuqina kwe-dimensional, kanye ne-warpage ephansi uma kuqhathaniswa ne-4 ~ 7mm yengilazi emfishane ye-polypropylene (GFPP) evamile.Ngaphezu kwalokho, ingilazi ende eqiniswe nge-polypropylene impahla ngeke ikhiqize ukukhasa okuphawulekayo ngisho noma ingaphansi kwezinga lokushisa eliphezulu elingu-100 ℃, futhi inokumelana nokukhasa okungcono kune-polypropylene yengilazi emfushane eqiniswe.
Ekhiqizweni elibunjiwe lomjovo, imicu yengilazi ende iyanyakaziswa ibe yisakhiwo senethiwekhi esinezinhlangothi ezintathu.Ngisho nangemva kokuba i-polypropylene substrate ishisiwe, inethiwekhi ye-fiber yengilazi ende isakha uhlaka lwamathambo e-glass fibre enamandla athile, kuyilapho i-fibre yengilazi emfishane ngokuvamile iba i-fiber engeyona amandla ngemva kokuvutha.uhlaka lwamathambo.Lesi simo sibangelwa ikakhulukazi ngoba isilinganiso sobude nobubanzi befiber eqinisayo sinquma umphumela wokuqinisa.Izihlungi namafayibha engilazi amafushane anesici esibalulekile esingaphansi kwe-100 awanawo amandla okuqiniswa, kuyilapho imicu yengilazi emide enesici esibalulekile esingaphezu kuka-100 idlala indima yokuqinisa.
Uma kuqhathaniswa nezinto zensimbi nezinto eziyinhlanganisela ye-thermosetting, ipulasitiki ende ye-fiber yengilazi inokuminyana okuphansi, futhi isisindo sengxenye efanayo singancishiswa ngo-20% kuya ku-50%.Ipulasitiki ye-fiber yengilazi ende inganikeza abaklami ukuguquguquka okukhulu kwedizayini, njengokubunjwa okubumbekayo okunobumo obuyinkimbinkimbi.Inani lezingxenye nezingxenye ezihlanganisiwe ezisetshenzisiwe zisindisa izindleko zesikhunta (ngokuvamile, izindleko zokubunjwa kwengilazi ende ye-fiber plastic injection zingaba ngu-20% wezindleko zokubumba izitembu zensimbi), futhi kunciphisa ukusetshenziswa kwamandla (ukusetshenziswa kwamandla okukhiqiza amapulasitiki amaplastiki ama-fiber amade. i-60% kuphela yemikhiqizo yensimbi %~80%, 35% ~ 50% yemikhiqizo ye-aluminium), okwenza inqubo yokuhlanganisa ibe lula.
Ukusetshenziswa kwe-Long Glass Fiber Reinforced Polypropylene Ezingxenyeni Zezimoto
I-polypropylene eqiniswe isikhathi eside isetshenziswa kuhlaka lomzimba wedeshibhodi yemoto, ubakaki webhethri, imojula yangaphambili, ibhokisi lokulawula, uhlaka lokusekela isihlalo, i-spare placenta, i-mudguard, ikhava ye-chassis, umgoqo womsindo, uhlaka lomnyango ongemuva, njll.
Imojula yangaphambili: Kumamojula angaphambili ezimoto, kusetshenziswa impahla ye-LGFPP (i-LGF yokuqukethwe 30%), ingahlanganisa izingxenye zensimbi zendabuko ezingaphezu kweziyi-10 ezifana nama-radiators, izipikha, ama-condenser, nabakaki kube kukonke;imelana nokugqwala kunezingxenye zensimbi.Ukuminyana kuncane, isisindo sincishiswa cishe ngo-30%, futhi sinezinga eliphakeme lenkululeko yokuklama.Ingasetshenziswa kabusha ngokuqondile ngaphandle kokuhlunga nokucubungula;kunciphisa izindleko zokukhiqiza futhi kunezinzuzo ezisobala ekunciphiseni izindleko.
I-Instrument panel body skeleton: Okwezinto ezithambile zephaneli yezinsimbi zamathambo, kusetshenziswa impahla ye-LGFPP inamandla aphezulu, i-modulus yokugoba ephakeme, kanye noketshezi olungcono kunezinto ezigcwele ze-PP.Ngaphansi kwamandla afanayo, ubukhulu bomklamo wephaneli yensimbi bungancishiswa ukuze kuncishiswe isisindo , Umphumela ojwayelekile wokulahlekelwa isisindo cishe u-20%.Ngesikhathi esifanayo, ubakaki wephaneli wezinsimbi ezivamile wezingxenye eziningi ungathuthukiswa ube imojuli eyodwa.Ngaphezu kwalokho, ukukhethwa kwezinto ezibonakalayo zomzimba wepayipi elincibilika ngaphambili kanye nohlaka olumaphakathi lwedeshibhodi ngokuvamile luyinto efanayo nohlaka oluyinhloko lwedeshibhodi, olungathuthukisa nakakhulu umphumela wokunciphisa isisindo.
Isihlalo esingemuva: Ingangena esikhundleni sohlaka lwensimbi oluvamile ukuze ithole ukuncishiswa kwesisindo esingu-20%, futhi inenkululeko ehle kakhulu yokuklama nokusebenza kokusebenza komshini, nezici ezifana nesikhala sokuhlala esinwetshiwe.
Ukubaluleka kwesicelo se-fiber yengilazi ende eqiniswe i-polypropylene emkhakheni wezimoto
Ngokuphathelene nokushintshwa kwezinto ezibonakalayo, imikhiqizo ye-polypropylene eqinisiwe yengilazi ende inganciphisa isisindo kanye nezindleko ngesikhathi esifanayo.Esikhathini esedlule, izinto eziqinisiwe zengilazi ezimfushane zazithatha indawo yensimbi.Eminyakeni yamuva nje, ngokusetshenziswa nokuthuthukiswa kwezinto ezingasindi, izinto zokwakha ze-polypropylene zengilazi ende ziye zashintsha kancane kancane amapulasitiki aqiniswe ngengilazi emifushane ezingxenyeni eziningi zezimoto, ezithuthukiswa ngokwengeziwe.Ucwaningo nokusebenzisa izinto ze-LGFPP ezimotweni.
