iimveliso

Ngenxa yokuqhubela phambili ngokukhawuleza kwe-"New Four Modernizations" kwishishini leemoto (Ukukhanya, Umbane, Ubukrelekrele), iiplastiki zobunjineli ziyaqhubeka nokuvelisa izinto ezintsha ezingazange zibonwe ngaphambili. Phakathi kwezinye iindlela ezininzi ezingasetyenziswayo endaweni yesinyithi, **PP long glass fiber reinforced material (PP-LGF)** iye yaba lukhetho olukhethwayo kwiindawo zesakhiwo seemoto kunye nezixhobo zangaphakathi ezisebenzayo, ngenxa yamandla ayo akhethekileyo, ukumelana nokudinwa, kunye nokukwazi kwayo "ukwenziwa kwesinyithi seplastiki."

Njengenkampani ebandakanyeka kakhulu kweli candelo, iJurong Best Composite Materials Co., Ltd. ivelisa uthotho lwePP-GF30, PP-GF40, kunye nePP-GF50, olugubungela ngokuchanekileyo uluhlu olupheleleyo lweemfuno ukusuka kwizakhiwo ezithwala umthwalo wesibini ukuya kwiindawo ezinobunzima obukhulu. Ngezantsi, sijonga ingqiqo ethile yesicelo kunye nexabiso lezi zinto kwizinto ezintathu ezibalulekileyo: isiseko se-shift lever, isigqubuthelo senjini, kunye ne-sunroof rail.

I. Isiseko seShift Lever (Ibracket yeGearshift Mechanism): Ibhalansi Phakathi kokuqina okuphezulu kunye nokumelana nokuqhekeka

Inkcazo yeSimo sesicelo:

Isiseko se-shift lever sikwindawo ye-central console yesithuthi. Asigcini nje ngokuba namandla omqhubi okutshintsha kodwa sikwakhusela nendlela entsonkothileyo yokutshintsha ye-elektroniki. Iziseko zesinyithi zemveli zinzima kwaye zinokuba neengxaki ze-NVH (Ingxolo, Ukungcangcazela, Ubunzima).

Isisombululo sezinto: PP-GF40 (Umlinganiselo weGolide) Kolu setyenziso, i-PP-LGF enomxholo wefayibha yeglasi engama-40% lukhetho olungabizi kakhulu.

Ukuhambelana Kokusebenza Koomatshini: Xa kuthelekiswa ne-PP-GF30, i-PP-GF40 idla ngokufikelela kwi-flexural modulus engaphezulu kwe-6000 MPa, nto leyo enika ukumelana okuphezulu kokuguquguquka. Oku kuqinisekisa ukuba ngexesha lokutyhala nokutsala rhoqo ngumqhubi, isiseko asishukumi okanye sitshintshe, sigcina imvakalelo yokutshintsha koomatshini echanekileyo.

Uphononongo lweTyala kunye neZiphumo: Umenzi wemoto odibeneyo omkhulu utshintshe isiseko waya kwi-PP-GF40 kuphuculo lwemodeli. Iziphumo zibonise ukuba kuvavanyo lokujikeleza kobushushu ukusuka kwi--35°C ukuya kwi-85°C, i-PP-GF40 ayizange igcine ukuqina okufana ne-nylon kuphela kodwa ikwanciphise neendleko malunga ne-20-25%. Ukongeza, isebenzisa uxinano oluphantsi lwe-PP, ifikelele ekunciphiseni ubunzima obuyinxenye enye ngaphezulu kwe-15%.

Izinto ekufuneka ziqwalaselwe kwimveliso:

Ulawulo lweWarpage: Isiseko se-shift lever sinejometri entsonkothileyo enemingxuma emininzi yokuyifaka nokufumana indawo. Nangona i-PP-GF40 inokugeleza okungcono kune-PA, uyilo olufanelekileyo lwesango (ngcono ii-valve gate hot runners) luyadingeka ukulawula ukujongwa kwefayibha yeglasi kunye nokuphepha i-warpage ebangelwa kukuncitshiswa kwe-anisotropic.

Amandla oQhagamshelo: Ngenxa yokuba i-PP ayinayo i-polarity ininzi, ukuba isiseko sifuna izikrufu ezithwala umthwalo, kuyacetyiswa ukuba uyile izinto zokufaka zesinyithi okanye usebenzise i-ultrasonic welding ukuze uphephe ukuqhekeka koxinzelelo okubangelwa kukuzidibanisa ngqo nezikrufu.

II. Isigqubuthelo senjini (Isigqubuthelo se-Intake Manifold / Isigqubuthelo sentloko yesilinda): Imfazwe yokunyamezela kwi-"Steamer" yobushushu obuphezulu

Inkcazo yeSimo sesicelo:

Isiciko senjini sikwindawo engundoqo yegumbi lenjini, xa sidibana nomoya oshushu ixesha elide, umphunga weoyile, kunye namaqondo obushushu aphezulu (ixesha elide yi-120-140°C). Iimfuno eziphambili kukumelana nokuguga kobushushu ixesha elide kunye nokuzinza kobukhulu.

Isisombululo sezinto: PP-GF30 (Uphuculo oluZinzisiweyo kuBushushu)

Nangona i-PP-GF30 iludidi oluqinisiweyo olusetyenziswa ngokubanzi, usetyenziso olujikeleze injini lufuna ukulungiswa okukhethekileyo kokuzinzisa ubushushu (uHlala luQinisekile).

Amandla Okudinwa Okuphezulu: Kwi-PP yesiqhelo ye-short-glass-fiber, ukuhamba kwe-molecular chain kuyanda xa kushushu kakhulu, nto leyo ebangela ukwehla okukhulu kobulukhuni. Nangona kunjalo, isakhiwo senethiwekhi esinemilinganiselo emithathu esenziwe yi-PP-GF30 ye-long-glass-fiber sisinika amandla okudinwa aphezulu kwi-120°C aphindwe kabini kunalawo e-PP yesiqhelo ye-short-glass-fiber eqinisiweyo, kwaye ingaphezulu nge-10% kune-nylon eqinisiweyo ye-glass-fiber, eyaziwa ngokumelana nobushushu.

Uphononongo lweTyala kunye neZiphumo: Umenzi weemoto waseYurophu watshintsha i-aluminium nge-PP-LGF30 ukuze enze isigqubuthelo senjini esihonjisiweyo. Iziphumo bezibalulekile: ngaphandle kokunciphisa ubunzima obungaphezulu kwama-40%, izinto ze-LGF zinciphise kakhulu ukudluliselwa kweentshukumo zenjini ezikhawulezayo ukuya kwikhabhinethi. Idlule kwi-150°C / uvavanyo lokuguga komoya oshushu lweeyure ezili-1000 ngaphandle kokuqhekeka okanye ukuguquka.

Izinto ekufuneka ziqwalaselwe kwimveliso:

Ivumba Eliphantsi kunye ne-VOC Ephantsi: Isigqubuthelo senjini sijongene nendawo yabakhweli, kwaye amaqondo obushushu aphezulu akhawulezisa ukukhutshwa kwe-VOC. Ngexesha lokudibanisa kunye nokubumba inaliti, ubushushu bokucheba kufuneka bulawulwe ngokungqongqo ukuze kuthintelwe ukubola kwe-PP kunye nokuveliswa kwe-aldehydes kunye neeketones, ukuqinisekisa inqanaba levumba ≤ 3.0.

Ubude Bokugcinwa Kwefayibha Yeglasi: Le yeyona mfihlo iphambili yezinto ze-LGF. Izikrufu ezichetywe kancinci kufuneka zisetyenziswe ngexesha lokubumba inaliti ukuqinisekisa ukuba ubude befayibha yeglasi kwinxalenye egqityiweyo buhlala phakathi kwe-3 mm kunye ne-6 mm (ngokuchaseneyo ne-0.2-0.4 mm kwiifayibha ezimfutshane eziqhelekileyo). Ngaphandle koko, inzuzo yokuqinisa "ifayibha yeglasi ende" iyalahleka.

III. Isitimela seSunroof (Itshaneli yokukhupha amanzi / ifreyimu): Eyona nto iphambili ekufuneni ukuchaneka okuKhawulezayo nokuLungelelanisayo

Inkcazo yeSimo sesicelo:

Iireli zelanga ezibanzi zihlala zijikeleza uphahla lwesithuthi, zifuna ukuqina okuphezulu kakhulu kunye ne-coefficient ephantsi ye-linear thermal expansion (CLTE). Iireli zesinyithi zemveli azinzima nje kuphela kodwa zikwafuna amanyathelo okucubungula anzima nabizayo.

Isisombululo sezinto: PP-GF50 (Umgangatho weFlagship oQiniseka kakhulu)

Ngomxholo wefayibha yeglasi engama-50%, eli linqanaba "lesilingi" lokuqinisa i-PP, elenzelwe iimfuno zokuqina okugqithisileyo.

Ukuqina Okufana Nesinyithi: I-PP-GF50 idla ngokufikelela kwimodulus egobileyo engaphezulu kwe-10,000 MPa. Oku kuvumela iireyile ze-sunroof ezibhityileyo nezinodonga oluncinci ukuba zigcine zithe tye phantsi kobushushu obujikelezayo, ukuqinisekisa ukutyibilika kweglasi okuthambileyo kunye nokungabikho kwengxolo engaqhelekanga.

I-CLTE ephantsi: Ulwakhiwo lwenethiwekhi yeefayibha zeglasi ezinde luthintela ngokufanelekileyo ukwanda/ukucutheka kobushushu be-matrix ye-PP, lunciphisa i-CLTE yayo ukusuka kwi-10-15×10⁻⁵/K kwi-PP eqhelekileyo ukuya kwi-2-3×10⁻⁵/K (kufutshane namanqanaba e-aluminium alloy), lusombulula ngempumelelo imiba yokubopha umzila ebangelwa kukwanda/ukucutheka kobushushu.

Uphononongo lweTyala kunye neZiphumo: Umenzi weemoto ophambili waseTshayina usebenzise i-PP-LGF50 ukutshintsha ii-aluminium extrusions kwiireyile ze-sunroof zeSUV yakhe ephambili. Oku kufezekise ukwehla kobunzima ngama-30% ngenxalenye nganye kwaye kwadibanisa izibiyeli zesinyithi ezininzi kwinxalenye ebunjiweyo, kunciphisa amanyathelo okuhlanganisa ngamahlanu kwaye kunciphisa kakhulu iindleko zokuvelisa zizonke.

Izinto ekufuneka ziqwalaselwe kwimveliso:

Ukuqhakaza kweFayibha yeGlasi: Ngenxa yokuba i-GF50 inomxholo ophezulu wefayibha, "ifayibha yeglasi eqhakaza" kumphezulu wenxalenye ixhaphakile, nto leyo echaphazela inkangeleko. Amaqondo obushushu aphezulu okubola (80-100°C) kunye neteknoloji yobushushu obukhawulezayo/yokupholisa kunye nemiphezulu yokubola enobume obuhle kuyacetyiswa ukuze kugqunywe okanye kufunxwe le micu.

Ukumelana nemozulu: Ii-sunroofs zichatshazelwa ngamanzi kunye nemitha ye-UV. Kufuneka kongezwe izinto ezigcina ubushushu kwi-carbon black kunye ne-UV stabilizers kwifomyula ukuthintela ukonakala kwezinto kunye nokutsalwa yitshokhwe phantsi kokukhanya kwe-UV.—

IV. Isishwankathelo kunye neMbono yoShishino

Izinto zefayibha yeglasi ende yePP azisezo "ziiplastiki" nje, kodwa zintsonkothile "zizisombululo zezinto ezidityanisiweyo."

I-PP-GF30 ludidi oluqhelekileyo, olufanelekileyo kwizinto ezijikeleze injini (ezifana nezigqubuthelo) ezifuna indibaniselwano elungeleleneyo yokumelana nobushushu kunye nokusebenza ngokubanzi. Ikwalukhetho lokuqala kwiindawo zesakhiwo sangaphakathi, ukulinganisela ukuqina kunye nokuqina, kwaye ingahlengahlengiswa kwiziseko ze-shift lever kunye nee-sunroof rails.

I-PP-GF40 yeyona ndlela ilungileyo yokutshintsha i-nylon. Njenge-universal grade enamandla aphakathi ukuya kwaphezulu, igubungela zonke izinto ezintathu eziphambili, ukulinganisela ukusebenza kunye neendleko. Ibonelela ngokusebenza kakuhle kunye neendleko kwiindawo zesakhiwo ezifana neziseko ze-shift lever.

I-PP-GF50 sisixhobo esinamandla "sokutshintsha isinyithi ngeplastiki," sigxile kwiindawo ezinkulu zesakhiwo ezineemfuno zokuqina okuphezulu kakhulu, njengee-sunroof rails kunye neemodyuli zangaphambili. Yenzelwe ukusetyenziswa kweendawo zenjini ezinomthwalo omninzi, inika ukuqina okuphezulu kakhulu, ukumelana nobushushu, kunye nokumelana nokuqhekeka, igxile kakhulu kwizigqubuthelo zenjini.

Njengoko imfuno yokutshintsha kwezibane zemoto ukusuka "kwizinto ezicetyiswayo" ukuya "kwizinto eziyimfuneko," imida yokusetyenziswa kwezinto zePP zeglasi ende-ifayibha kwiindawo zesakhiwo semoto iyaqhubeka nokukhula.

Ndixelele ukuba ufuna naluphi na utshintsho kwinguqulelo okanye kwifomathi.
