zvigadzirwa

Nekufambira mberi nekukurumidza kwe "New Four Modernizations" yeindasitiri yemotokari (Lightweighting, Electricization, Intelligence), mapurasitiki einjiniya ari kuita hunyanzvi husina kumboonekwa. Pakati pezvimwe zvinhu zvakawanda zvinotsiva simbi, **PP long glass fiber reinforced material (PP-LGF)** yave sarudzo inofarirwa yezvikamu zvemotokari uye zvikamu zvinoshanda mukati, nekuda kwesimba rayo rakanaka, kuramba kuneta, uye kugona kwayo "plastic metallization".

Sekambani ine basa guru munyaya iyi, Jurong Best Composite Materials Co., Ltd. inogadzira mhando dzePP-GF30, PP-GF40, uye PP-GF50, idzo dzinonyatso fukidza zvese zvinodiwa kubva kuzvivakwa zvinotakura mutoro kusvika kuzvikamu zvemapfupa zvine kusimba kwakanyanya. Pazasi, tinotarisa mashandisirwo chaiwo uye kukosha kwezvinhu izvi muzvikamu zvitatu zvakakosha: shift lever base, injini cover, uye sunroof rail.

I. Chigadziko cheShift Lever (Gearshift Mechanism Bracket): Kuenzana Pakati peHigh Stiffness neCreep Resistance

Tsananguro yeChiitiko Chekushandisa:

Chigadziko che "shift lever" chiri munzvimbo yepakati pemota. Hachingogumiri pakushandisa simba remutyairi rekuchinja mota asiwo chinodzivirira mashandiro akaomarara e "electronic shift mechanism". Zvigadziko zvesimbi zvechinyakare zvinorema uye zvinowanzobatwa nematambudziko eNVH (Noise, Vibration, Harshness).

Mhinduro Yezvinhu: PP-GF40 (Chiyero Chegoridhe) Pakushandisa uku, PP-LGF ine 40% yegirazi fiber isarudzo inodhura zvishoma.

Kuenderana Kwekushanda Kwemuchina: Zvichienzaniswa nePP-GF30, PP-GF40 inowanzoita kuti flexural modulus ive pamusoro pe6000 MPa, zvichipa resistance yakanyanya. Izvi zvinoita kuti panguva yekusundidzirwa nekudhonzwa nemutyairi kakawanda, hwaro hahutsvedzeri kana kutenderera, zvichiramba zvichiita kuti mechanical shift iite seyakanaka.

Chidzidzo Chenyaya & Mhedzisiro: Kambani huru yemubatanidzwa yakachinja base kuenda kuPP-GF40 mukuvandudza modhi. Zvakabuda zvakaratidza kuti mukuyedza kupisa kubva pa -35°C kusvika 85°C, PP-GF40 haina kungoramba yakasimba senylon chete asiwo yakaderedza mitengo neinenge 20-25%. Pamusoro pezvo, ichishandisa density yakaderera yePP, yakawana kudzikiswa kwehuremu hwechikamu chimwe chete neanopfuura 15%.

Zvaunofanira Kufunga Nezvekugadzira:

Kudzora Warpage: Hwaro hweshift lever hune maitiro akaomarara ane maburi akawanda ekumisikidza uye ekuwana nzvimbo. Kunyangwe PP-GF40 ichikwanisa kuyerera zviri nani pane PA, dhizaini chaiyo yegedhi (zviri nani kushandisa valve gate hot runners) inodiwa kudzora girazi fiber orientation uye kudzivirira warpage inokonzerwa nekuderera kweanisotropic.

Simba reKubatanidza: Nekuda kwekusagadzikana kwePP, kana hwaro huchida masikuruu anorema, zvinokurudzirwa kugadzira masikuruu esimbi kana kushandisa welding ye ultrasonic kudzivirira kutsemuka kunokonzerwa ne direct-tapping screw threading.

II. Chifukidziro cheInjini (Chifukidziro cheIntake Manifold / Chifukidziro cheMusoro weSilinda): Hondo yekutsungirira mu "Steamer" inodziya zvakanyanya

Tsananguro yeChiitiko Chekushandisa:

Chifukidziro cheinjini chiri pakati penzvimbo yeinjini, chinosangana nemhepo inopisa kwenguva refu, utsi hwemafuta, uye tembiricha yakakwirira (kwenguva refu 120-140°C). Zvinodiwa zvikuru ndezvekuti irambe ichidzivirira kupisa kwenguva refu uye kuti isanyanya kugadzikana.

Mhinduro Yezvinhu: PP-GF30 (Kusimudzira Kupisa)

Kunyangwe PP-GF30 iri giredhi rakasimbiswa rine chinangwa chakajairika, mashandisirwo akapoteredza injini anoda kugadziriswa kwakakosha kwekudzikamisa kupisa (Heat Aging Stabilized).

Simba Rekuneta Pakupisa Kwakakwirira: MuPP yegirazi pfupi, kufamba kwemasero emuchina kunowedzera kana tembiricha yakakwira, zvichikonzera kudzikira kukuru kwekuoma. Zvisinei, chimiro che network chine mativi matatu chakagadzirwa nePP-GF30 yegirazi refu chinoipa simba rekuneta pakupisa kwakakwirira pa120°C rinopetwa kaviri kupfuura PP yakajairika yegirazi pfupi, uye kunyange 10% yakakwira kupfuura nylon yakasimbiswa negirazi, inozivikanwa nekudzivirira kupisa kwayo.

Chidzidzo Chemuenzaniso & Mhedzisiro: Kambani yemotokari yekuEurope yakatsiva aruminiyamu nePP-LGF30 kuti ive chifukidziro chekushongedza injini. Mhedzisiro yacho yaive yakakosha: kunze kwekuderedzwa kwehuremu neanopfuura 40%, zvinhu zveLGF zvakaderedza zvakanyanya kutapurirana kwemhepo inotenderera zvakanyanya kuenda kukamuri. Yakapfuura bvunzo dze150°C / 1000-awa dzekupisa pasina kutsemuka kana kuchinja.

Zvaunofanira Kufunga Nezvekugadzira:

Kunhuhwirira Kushoma & VOC Yakaderera: Chifukidziro cheinjini chinotarisana nekamuri revatakurwi, uye tembiricha yepamusoro inokurumidza kubuda kweVOC. Munguva yekubatanidza uye kugadzira jekiseni, kupisa kwemoto kunofanirwa kudzorwa zvakasimba kudzivirira PP kuora uye kugadzirwa kwealdehydes nemaketone, zvichiita kuti hwema huve padanho re ≤ 3.0.

Kureba Kwekuchengetedza Fiber yeGirazi: Ichi ndicho chakavanzika chikuru chezvinhu zveLGF. Skuruu dzine kucheka kwakaderera dzinofanira kushandiswa panguva yekuumbwa kwejekiseni kuitira kuti kureba kwefiber yegirazi muchikamu chapera kurambe kuri pakati pe3 mm ne6 mm (kusiyana ne0.2-0.4 mm kune fibers pfupi dzakajairika). Zvikasadaro, kubatsira kwe "fiber yegirazi refu" kunorasika.

III. Njanji yeSunroof (Drain Channel / Furemu): Kutsvaga Kwekupedzisira Kwekureruka uye Kunyatsojeka

Tsananguro yeChiitiko Chekushandisa:

Marambi edenga remoto anowanzo tenderera padenga remota, achida kusimba kwakanyanya uye kuwedzera kwekupisa kwemagetsi kwakaderera (CLTE). Marambi esimbi echinyakare haangorevi chete kuti anorema asiwo anoda matanho akaomarara uye anodhura ekugadzirisa.

Mhinduro Yezvinhu: PP-GF50 (Giredhi reFlagship Rakasimba)

Ne50% yefiber yegirazi, iyi ndiyo "ceiling" level yePP rekusimbisa, yakagadzirirwa zvinodiwa zvakanyanya kuomarara.

Kusimba Kwakafanana Nesimbi: PP-GF50 inowanzoita kuti denga rive ne flexural modulus pamusoro pe 10,000 MPa. Izvi zvinobvumira denga rezuva rakatetepa, rakatetepa kuti rirambe rakatwasuka kana tembiricha yachinja, zvichiita kuti girazi ritsvedzerere zvakanaka uye risanyanye kunzwika ruzha.

CLTE Yakaderera: Maumbirwo enetwork yefibers refu dzegirazi anonyatso dzivisa kuwedzera/kukwenya kwePP matrix, zvichideredza CLTE yayo kubva pa10-15×10⁻⁵/K yePP yakajairika kusvika pa2-3×10⁻⁵/K (pedyo nemazinga ealuminium alloy), zvichigadzirisa zvinobudirira matambudziko ekubatanidza njanji anokonzerwa nekuwedzera/kukwenya kwekupisa.

Chidzidzo Chemuenzaniso & Mhedzisiro: Kambani yemotokari yekuChina ine mukurumbira yakashandisa PP-LGF50 kutsiva aruminiyamu inoburitsa zvinhu padenga remotokari yayo huru yeSUV. Izvi zvakaderedza huremu ne30% pachikamu chimwe nechimwe uye zvakabatanidza mabhureki esimbi akawanda muchikamu chakaumbwa, zvichideredza matanho ekubatanidza neshanu uye zvakaderedza zvakanyanya mari yekugadzira.

Zvaunofanira Kufunga Nezvekugadzira:

Kutumbuka kweGlass Fiber: Nehuwandu hwakawanda hweGF50, "kutumbuka kwegirazi fiber" pamusoro pechikamu kwakajairika, zvichikanganisa chitarisiko. Kupisa kwakanyanya kwevhu (80-100°C) nehunyanzvi hwekupisa nekukurumidza/kutonhora uye nzvimbo dzakapfava dzevhu zvinokurudzirwa kuti zvifukidze kana kunwisa vhudzi.

Kusamira Kwemamiriro Ekunze: Madenga ezuva anobatwa nemvura nemwaranzi yeUV. Kabhoni nhema uye zvinosimbisa UV zvinofanirwa kuwedzerwa muchimiro ichi kudzivirira kuora kwezvinhu uye kudonha kwechoko kana zvasangana neUV.—

IV. Pfupiso uye Maonero Eindasitiri

Zvinhu zvePP zvegirazi refu hazvisisiri "mapurasitiki" chete, asi "mhinduro dzezvinhu zvakasanganiswa" dzakaoma.

PP-GF30 imhando yepasi rose, yakakodzera zvikamu zvakatenderedza injini (zvakaita semavhavha) zvinoda musanganiswa wakaringana wekudzivirira kupisa uye kushanda kwakazara. Ndiyo sarudzo yekutanga yezvikamu zvemukati, kuenzana kwekusimba uye kuomarara, uye inogona kugadziriswa kune mabhesi e shift lever uye sunroof rails.

PP-GF40 ndiyo sarudzo yakanakisisa yekutsiva nayiloni. Semhando yepasi rose ine simba repakati nepakati kusvika pakakwirira, inofukidza zvikamu zvitatu zvikuru, zvinoenzanisa mashandiro uye mutengo. Inopa mashandiro uye kushanda zvakanaka muzvikamu zvechivakwa zvakaita sema shift lever bases.

PP-GF50 chishandiso chine simba che "kutsiva simbi nepurasitiki," inonyanya kugadzira zvikamu zvikuru zvechivakwa zvine zvinodiwa zvakanyanya kuomarara, zvakaita sema sunroof rails nema front-end modules. Yakagadzirirwa kushandiswa kwema compartment einjini ane mutoro wakawanda, inopa kuomarara kwakanyanya, kudzivirira kupisa, uye kuramba kukambaira, ichinyanya kutarisa ma cover einjini.

Sezvo kudiwa kwekuchinja kwezviyereso zvemotokari kubva pakuchinja kwe "zvinokurudzirwa" kuenda ku "zvinosungirwa," miganhu yekushandisa yezvinhu zvePP zvegirazi refu muzvikamu zvekuvaka mota iri kuramba ichikura.

Ndizivisei kana muchida kugadzirisa chero shanduko kana mafomati.
