imikhiqizo

Ngokuthuthuka okusheshayo kwe-"New Four Modernizations" embonini yezimoto (Ukukhanya, Ugesi, Ubuhlakani), amapulasitiki obunjiniyela aqala ukusebenza ngendlela entsha engakaze ibonwe. Phakathi kwezinye izindlela eziningi ezingasetshenziswa esikhundleni sensimbi, **PP long glass fiber reinforced material (PP-LGF)** isibe ukukhetha okuthandwayo kwezingxenye zesakhiwo sezimoto kanye nezingxenye zokusebenza kwangaphakathi, ngenxa yamandla ayo amahle kakhulu, ukumelana nokukhathala, kanye nekhono eliyingqayizivele "lokwenziwa kwensimbi yepulasitiki."

Njengenkampani ehileleke kakhulu kulo mkhakha, iJurong Best Composite Materials Co., Ltd. ikhiqiza uchungechunge lwe-PP-GF30, PP-GF40, kanye ne-PP-GF50, oluhlanganisa kahle uhla oluphelele lwezidingo kusukela ezakhiweni ezithwala umthwalo wesibili kuya ezingxenyeni zamathambo ezinokuqina okuphezulu. Ngezansi, sihlola indlela ethile yokusebenzisa kanye nenani lalezi zinto ezingxenyeni ezintathu ezibalulekile: isisekelo se-shift lever, ikhava yenjini, kanye nesitimela se-sunroof.

I. Isisekelo Se-Shift Lever (I-Gearshift Mechanism Bracket): Ibhalansi Phakathi Kokuqina Okuphezulu Nokumelana Nokucwila

Incazelo Yesimo Sesicelo:

Isisekelo se-shift lever sitholakala endaweni ye-central console yemoto. Asigcini nje ngokuba namandla okushintsha komshayeli kodwa futhi sivikela nendlela eyinkimbinkimbi yokushintsha kagesi. Izisekelo zensimbi zendabuko ziyasinda futhi zithambekele ezinkingeni ze-NVH (Umsindo, Ukudlidliza, Ubukhali).

Isixazululo Sezinto Ezibalulekile: PP-GF40 (Isilinganiso Segolide) Kulolu hlelo lokusebenza, i-PP-LGF enokuqukethwe kwe-fiber yengilazi engu-40% iyisinqumo esingabizi kakhulu.

Ukufaniswa Kokusebenza Komshini: Uma kuqhathaniswa ne-PP-GF30, i-PP-GF40 ivame ukufeza i-modulus eguquguqukayo engaphezu kuka-6000 MPa, okuhlinzeka ngokumelana okuphezulu kokuguquguquka. Lokhu kuqinisekisa ukuthi ngesikhathi sokusunduza nokudonsa njalo ngumshayeli, isisekelo asinyakazi noma sinyakaze, sigcina umuzwa oqondile wokushintsha komshini.

Ucwaningo Lwesibonelo kanye Nemiphumela: Umkhiqizi omkhulu wezimoto ezihlangene ushintshe isisekelo saba yi-PP-GF40 ekuthuthukisweni kwemodeli. Imiphumela ibonise ukuthi ekuhlolweni kokujikeleza kokushisa kusuka ku--35°C kuya ku-85°C, i-PP-GF40 ayizange igcine ukuqina okufana ne-nylon kodwa futhi yehlise nezindleko cishe ngo-20-25%. Ngaphezu kwalokho, isebenzisa ubuningi obuphansi be-PP, ifinyelele ukwehla kwesisindo sengxenye eyodwa ngaphezu kuka-15%.

Izinto Okumelwe Uzicabangele Zokukhiqiza:

Ukulawulwa Kwe-Warpage: Isisekelo se-shift lever sinokwakheka okuyinkimbinkimbi okunezimbobo eziningi zokufaka nokuthola indawo. Nakuba i-PP-GF40 inokugeleza okungcono kune-PA, ukwakheka kwesango okufanele (okungcono kakhulu ama-valve gate hot runners) kuyadingeka ukulawula ukuqondiswa kwefayibha yengilazi nokugwema i-warpage ebangelwa ukuncishiswa kwe-anisotropic.

Amandla Okuxhumana: Ngenxa yokuthi i-PP ine-polarity ephansi ngokwemvelo, uma isisekelo sidinga izikulufo ezithwala umthwalo, kuyalulekwa ukuklama izifakelo zensimbi noma ukusebenzisa ukushisela kwe-ultrasonic ukuze ugweme ukuqhekeka kokucindezeleka okubangelwa ukugoqa izikulufo ezizithinta ngqo.

II. Isembozo Senjini (Intake Manifold Cover / Cylinder Head Cover): Impi Yokukhuthazela E-“Steamer” Esezingeni Eliphezulu Lokushisa

Incazelo Yesimo Sesicelo:

Isembozo senjini sitholakala endaweni eyinhloko yegumbi lenjini, lapho sithintana khona isikhathi eside nomoya oshisayo, umusi kawoyela, kanye namazinga okushisa aphezulu (isikhathi eside esingu-120-140°C). Izidingo eziyinhloko ukumelana nokuguga kokushisa isikhathi eside kanye nokuqina kobukhulu.

Isixazululo Esibalulekile: PP-GF30 (Ukuthuthukiswa Okuzinzile Kokushisa)

Nakuba i-PP-GF30 iyizinga eliqinisiwe elijwayelekile, izinhlelo zokusebenza ezizungeze injini zidinga ukulungiswa okukhethekile kokuzinzisa ukuguga kokushisa (i-Heat Aging Stabilized).

Amandla Okukhathala Okuphezulu: Ku-PP evamile ye-fiber-glass-fibre, ukuhamba kwe-molecule chain kuyanda emazingeni okushisa aphezulu, okubangela ukwehla okukhulu kokuqina. Kodwa-ke, isakhiwo senethiwekhi esinezinhlangothi ezintathu esakhiwe yi-PP-GF30 ye-fiber-glass-long glass sinikeza amandla okukhathala aphezulu ku-120°C okuphindwe kabili kunaleyo ye-PP evamile ye-fiber-glass-fibre-reinforced, futhi ngisho nangaphezu kuka-10% kune-nylon eqiniswe yi-fiber-glass, eyaziwa ngokumelana kwayo nokushisa.

Ucwaningo Lwesibonelo kanye Nemiphumela: Umenzi wezimoto waseYurophu washintsha i-aluminium nge-PP-LGF30 ukuze kube yisembozo sokuhlobisa injini. Imiphumela yayibalulekile: ngaphandle kokunciphisa isisindo okungaphezu kuka-40%, izinto ze-LGF zanciphisa kakhulu ukudluliselwa kokudlidliza kwenjini okuvama kakhulu ekhabini. Yadlula ukuhlolwa kokuguga komoya oshisayo okungu-150°C / amahora angu-1000 ngaphandle kokuqhekeka noma ukuguqulwa.

Izinto Okumelwe Uzicabangele Zokukhiqiza:

Iphunga Eliphansi kanye ne-VOC Ephansi: Isembozo senjini sibhekene negumbi labagibeli, futhi amazinga okushisa aphezulu asheshisa ukukhishwa kwe-VOC. Ngesikhathi sokuhlanganiswa kanye nokubumbana komjovo, ukushisa okusheshisiwe kumele kulawulwe ngokuqinile ukuze kugwenywe ukuwohloka kwe-PP kanye nokukhiqizwa kwama-aldehydes nama-ketone, okuqinisekisa izinga lephunga ≤ 3.0.

Ubude Bokugcinwa Kwefayibha Yengilazi: Lena imfihlo eyinhloko yezinto ze-LGF. Izikulufo ezishefa kancane kumele zisetshenziswe ngesikhathi sokubumba umjovo ukuqinisekisa ukuthi ubude befayibha yengilazi engxenyeni eqediwe buhlala phakathi kuka-3 mm no-6 mm (ngokungafani no-0.2-0.4 mm wefayibha ezimfushane ezivamile). Ngaphandle kwalokho, inzuzo yokuqinisa "ifayibha yengilazi ende" iyalahleka.

III. Isitimela Sophahla Lwelanga (Isiteshi Sokukhipha Amanzi / Uhlaka): Ukuphishekela Okuphelele Kokucacisa Okulula Nobukhulu

Incazelo Yesimo Sesicelo:

Ama-rail e-sunroof ane-panoramic avame ukumboza uphahla lwemoto, adinga ukuqina okuphezulu kakhulu kanye ne-coefficient ephansi yokwandiswa kokushisa okuqondile (i-CLTE). Ama-rail ensimbi endabuko awagcini nje ngokuba nzima kodwa futhi adinga izinyathelo zokucubungula eziyinkimbinkimbi nezibizayo.

Isixazululo Sezinto Ezibalulekile: PP-GF50 (Ibanga Lokugqama Eliqinile Kakhulu)

Ngokuqukethwe kwefayibha yengilazi engu-50%, leli yizinga "lophahla" lokuqinisa i-PP, elenzelwe izidingo zokuqina okukhulu.

Ukuqina Okufana Nensimbi: I-PP-GF50 ivame ukuthola i-modulus eguquguqukayo engaphezu kwe-10,000 MPa. Lokhu kuvumela izinsimbi zophahla lwelanga ezincane nezinodonga oluncane ukuthi zigcine ziqondile ngaphansi kokujikeleza kokushisa, okuqinisekisa ukushelela kwengilazi okubushelelezi futhi kungabikho msindo ongajwayelekile.

I-CLTE Ephansi: Isakhiwo senethiwekhi yemicu yengilazi ende sivimbela ngempumelelo ukwanda/ukufinyela kokushisa kwe-matrix ye-PP, sinciphisa i-CLTE yayo kusuka ku-10-15×10⁻⁵/K ye-PP evamile kuya ku-2-3×10⁻⁵/K (eduze kwamazinga e-aluminium alloy), sixazulula ngempumelelo izinkinga zokubopha isitimela ezibangelwa ukwanda/ukufinyela kokushisa.

Ucwaningo Lwesibonelo kanye Nemiphumela: Umkhiqizi wezimoto ohamba phambili waseShayina usebenzise i-PP-LGF50 ukufaka esikhundleni se-aluminium extrusions ye-sunroof rails ye-SUV yayo eyinhloko. Lokhu kwafeza ukwehla kwesisindo ngo-30% ngengxenye ngayinye futhi kwahlanganisa ama-bracket ensimbi amaningi engxenyeni ebunjiwe, kunciphisa izinyathelo zokuhlanganisa ngamahlanu futhi kwehlisa kakhulu izindleko zokukhiqiza eziphelele.

Izinto Okumelwe Uzicabangele Zokukhiqiza:

Ukuqhakaza Kwefayibha Yengilazi: Njengoba inokuqukethwe okuphezulu kwefayibha ye-GF50, "ukuqhakaza kwefayibha yengilazi" ebusweni bengxenye kuvamile, okuthinta ukubukeka. Amazinga okushisa aphezulu esikhunta (80-100°C) ngobuchwepheshe bokushisa okusheshayo/bokupholisa kanye nezindawo zesikhunta ezinobunjwa obuhle kuyanconywa ukuze kumbozwe noma kumuncwe imicu.

Ukumelana Nesimo Sezulu: Uphahla lwelanga luvezwa emanzini nasemisebeni ye-UV. Umnyama wekhabhoni kanye neziqinisi ze-UV kumele zengezwe ekwakhiweni ukuze kuvinjelwe ukuwohloka kwezinto kanye nokushiswa ngetshokho ngaphansi kokuvezwa yi-UV.—

IV. Isifinyezo kanye Nombono Wemboni

Izinto zefayibha yengilazi ende ye-PP azisezona nje “ipulasitiki,” kodwa “izixazululo zezinto ezihlanganisiwe” eziyinkimbinkimbi.

I-PP-GF30 iyizinga elijwayelekile, elifanele izingxenye ezizungeze injini (njengezembozo) ezidinga inhlanganisela elinganiselayo yokumelana nokushisa kanye nokusebenza kahle. Futhi iyisinqumo sokuqala sezingxenye zesakhiwo sangaphakathi, ukulinganisela ukuqina nokuqina, futhi ingashintshwa ukuze isetshenziswe ezisekelweni ze-shift lever kanye ne-sunroof rails.

I-PP-GF40 iyisinqumo esingcono kakhulu sokushintsha inayiloni. Njengezinga eliphakathi kuya kweliphezulu elinamandla ajwayelekile, ihlanganisa zonke izingxenye ezintathu ezinkulu, ukulinganisela ukusebenza kanye nezindleko. Ihlinzeka kokubili ukusebenza kanye nokusebenza kahle kwezindleko ezingxenyeni zesakhiwo ezifana nezisekelo ze-shift lever.

I-PP-GF50 iyithuluzi elinamandla "lokufaka esikhundleni sensimbi ngepulasitiki," egxile ezingxenyeni ezinkulu zesakhiwo ezinezidingo zokuqina okuphezulu kakhulu, njengemijikelezo yelanga namamojula angaphambili. Yakhelwe ukusetshenziswa kwezingxenye zenjini ezithwala umthwalo omkhulu, inikeza ukuqina okuphezulu kakhulu, ukumelana nokushisa, kanye nokumelana nokukhukhuleka, ngokugxila okuyinhloko ezimbozweni zenjini.

Njengoba isidingo sokushintsha kwezibani zezimoto kusuka “kokunconywayo” kuya “kokuphoqelekile,” imingcele yokusetshenziswa kwezinto ze-PP ze-fiber-glass ende ezingxenyeni zesakhiwo sezimoto iyaqhubeka nokukhula.

Ngitshele uma udinga noma yikuphi ukulungiswa ekuhunyushweni noma ekufometheni.
