Umtya wokutywina wemoto (Ucango, ifestile, isibhakabhaka)
Umtya wokutywina wemoto
Umtya wokutywina wemoto yenye yamacandelo abalulekileyo, asetyenziswa kakhulu kumnyango, kwifestile, kumzimba wemoto, kwisibhakabhaka, kwityala le-injini kunye nebhokisi (imithwalo) yebhokisi njl njl, kunye nokugqunywa kwesandi, ukungabikho kothuli, ukungangeni kwamanzi kunye nomsebenzi wokudambisa, gcina kwaye ugcine incinci. okusingqongileyo ngaphakathi kwimoto, ukudlala umhlali wemoto, izixhobo zombane kunye nezomatshini kunye nezinto ezincedisayo zokukhusela okubalulekileyo.Ngophuhliso lweshishini leemoto, ukubaluleka kobuhle, ukhuseleko lokusingqongileyo kunye nomsebenzi otofotofo wokutywinwa komcu uya usiba obala.INKQUBO YOKUTHINISWA (i-auto-bile-SEALING SYSTEM) efakwe kwiindawo ezahlukeneyo zemoto iye yaphandwa ngokukodwa kwaye yaphuhliswa kwishishini leemoto zangaphandle, kwaye ukubaluleka kwayo kukutsala ingqalelo eyandayo.1. Ngokwegama leenxalenye zokutywina (iinxalenye), ulwahlulo lubandakanya: i-injini ye-HOOD seal, kwaye inokwahlulwa ibe ngaphambili, kwicala nangasemva;UKUtywinwa komnyango;IWINDOW izikrini zeWindows zangaphambili nasemva zomoya;I-SIDE itywina yefestile (i-SIDE Window seal);SUNROOF itywina;Itywina lomnyango oliziko;Umcu wokutywina wegroove yesikhokelo sefestile (i-GLASSRUN CHANNEL);Imicu yangaphakathi nangaphandle (i-watercut)(WAISTLINE);TINQWANE LESIQINISO;Umtya wokutywina wokuchasana nengxolo;Ezinje ngothuli.2. Ngokweempawu zokutywinwa, ingahle ihlelwe ngokwe-WEATHERSTRIP seal kunye netywina ngokubanzi.Phakathi kwazo, umtya wokutywina wemozulu uxhotyiswe ityhubhu ye-sponge bubble, enobushushu obungcono kunye nomsebenzi wokugcina ukufuma.Imicu yokutywina yemozulu exhaphakileyo ibandakanya umcu wokutywina wesakhelo socango, umtya wokutywina wesutikheyisi, umtya wecala le-injini, njl.njl. Imicu yokutywina eqhelekileyo esetyenziswa ngokubanzi ingaphambili nangasemva ngemicu yokutywina yefestile kunye nemicu yokutywina yefestile, yangaphakathi nangaphandle, njl njl. kuhlelo lwerubha oludityanisiweyo, lunokwahlulwa lube ngumtya wokutywina werabha osulungekileyo -- owenziwe ngerabha enye;Imicu emibini edityanisiweyo yokutywina -- yenziwe ngeglu eshinyeneyo kunye neglu egwebu olugwebu, ngokufuthi kwiglu eshinyeneyo kwicala le-axis equlethe imathiriyeli yesinyithi;Isitywina esihlanganisiweyo kathathu - siquka iindidi ezimbini ze-sealant (enye yazo inombala okhanyayo) kunye ne-sponge sealant, ngokuqhelekileyo iqulethe i-metal skeleton kunye nemicu eqinisiweyo ngaphakathi kwe-sealant.Imicu emine yokutywina edityanisiweyo-iShanghai Shenya Sealing parts Co., Ltd. iye yakhokela ekuphuhliseni nasekuveliseni icwecwe lokutywina elidityanisiweyo elenziwe ziintlobo ezi-4 zemathiriyeli yerabha, kumphezulu werabha (ityhubhu yeqamza) kwaye igqunywe ngomaleko obhityileyo. i-adhesive layer adhesive, ukwenzela ukuba kuphuculwe ngakumbi ubomi benkonzo yamatywina.4. Ngokohlobo lokuhlelwa kwezinto, zinokwahlulwa zibe ngumtya wokutywina werabha;Umtya wokutywina weplastiki;Thermoplastic elastomer seal strip.5. Ihlelwe ngokwemeko yonyango lomphezulu, umphezulu othile wokutywina emva konyango olongezelelweyo, unokohlulwa ube ngumtya wokutywina;Umtya wokutywina wokugquma ubuso;Kukho imicu yokutywina ilaphu.6. Ukuhlelwa komsebenzi okhethekileyo, umcu wokutywina unomsebenzi okrelekrele we-elektroniki, onjengomcu wokutywina wokutywina.
(2) Isixhobo somtya wokutywina
Irabha ye-EPDM
I-Ethylene propylene diene diene (EPDM) yenziwe nge-polymerization ye-ethylene kunye ne-propylene monomers kunye nenani elincinci le-non-conjugated diolefin.Ulwakhiwo lwepolymer lubonakaliswa ngamabhondi angenawo unsaturated kwikhonkco eliphambili kunye neebhondi eziphindwe kabini ezingaxutywanga kwikhonkco legatsha.Ke ngoko, inokumelana nemozulu ebalaseleyo, ukumelana nobushushu, ukuxhathisa kwe-ozone, ukuchasana kwe-uv kunye nokusebenza kakuhle kokusetyenzwa kunye noxinzelelo oluphantsi loguquko olusisigxina, ngoko ke yeyona nto ikhethwayo yokuvelisa imicu yokutywina.Okwangoku, uninzi lwezixhobo zokutywina zemoto zisebenzisa i-EPDM njengeyona mathiriyeli ikrwada.Ngokwamacandelo ahlukeneyo kunye nemisebenzi yemicu yokutywina, kwisicelo esisebenzayo, i-vulcanization, ukukhuselwa, ukuqinisa, izixhobo zokusebenza zenkqubo kunye nezinto ezikhethekileyo ezinikezelweyo (ezifana nombala, i-agent ye-foaming) zongezwa kwizinto ze-EPDM ukwenza i-adhesive dense (kubandakanya i-adhesive emnyama. kunye nokuncamathelisa umbala) kunye nokuncamathelisa isipontshi.Umtya wokutywina wemoto ubandakanya ubukhulu becala obuthambileyo kunye nokumelana nokuguqulwa koxinzelelo, ukumelana nokwaluphala, i-ozone, isenzo sekhemikhali, uluhlu olubanzi lobushushu (-40 ℃ ~ + 120 ℃) I-EPDM igwebu lerabha kunye ne-composite eshinyeneyo, equlethe ukulungiswa kwentsimbi eyodwa. kunye ne-buckle yolwimi, yomelele, kulula ukuyifaka.Kudala ifaniswe nabavelisi abakhulu beemoto.
Iimpawu zemveliso
Uluhlu lobushushu olucetyiswayo:
Izinto ze-EPDM -40 °F -248 °F (-40℃ -120 ℃)
Izinto zentsimbi zangaphakathi: ucingo lwentsimbi okanye ishidi lentsimbi
Irabha yendalo
Irabha yendalo luhlobo lwepolyisoprene njengeyona nto iphambili kwikhompawundi yepolymer yendalo, ifomula yemolekyuli yi (C5H8) N, 91% ~ 94% yamacandelo ayo yirubber hydrocarbon (polyisoprene), enye iprotheyini, i-fatty acid, uthuthu, iswekile. kunye nezinye izinto ezingezizo irabha.Irabha yendalo yeyona isetyenziswa ngokubanzi irabha yenjongo jikelele.Ngenxa yokuba irabha yendalo inoluhlu lweempawu zomzimba kunye neekhemikhali, ngakumbi ukomelela kwayo okugqwesileyo, ukugquma, ukwahlula amanzi kunye neplastiki kunye nezinye iimpawu, kwaye, emva konyango olufanelekileyo, inokumelana ne-oyile, ukuxhathisa kweasidi, ukuxhathisa kwealkali, ukuxhathisa ubushushu, ukumelana nokubanda, ukumelana noxinzelelo, ukumelana nokugqoka kunye nezinye iimpawu ezixabisekileyo, ngoko ke, kunoluhlu olubanzi lokusetyenziswa.Ngokomzekelo, ukusetyenziswa kwansuku zonke kwezicathulo zemvula, iingxowa zamanzi afudumeleyo, i-elastic;Iiglavu zotyando, iityhubhu zotofelo-gazi, iikhondom ezisetyenziswa kwicandelo lezonyango nelezempilo;Zonke iintlobo zamatayara asetyenziswa kuthutho;Amabhanti okuhambisa, amabhanti okuthutha, iiglavu ezixhathisa iasidi kunye nealkali ukwenzela ukusetyenziswa kwemizi-mveliso;Ukusetyenziswa kwezolimo kwimibhobho yamanzi kunye nokunkcenkceshela, iingxowa ze-ammonia;Iibhaloni ezandisiweyo zovavanyo lwemozulu;Izixhobo zokutywina kunye nezothusayo zovavanyo lwenzululwazi;Iinqwelo-moya, iitanki, izixhobo zokudubula kunye neemaski zerhasi ezisetyenziselwa ukukhusela;Kwaneerokhethi, iisathelayithi zomhlaba ezenziweyo neziphekepheke kunye nezinye iimveliso ezintsonkothileyo zenzululwazi nezobuchwepheshe azinakwahlulwa kwirabha yendalo.Okwangoku, kukho izinto ezingaphezu kwama-70,000 ehlabathini ezenziwe ngokuyinxenye okanye ngokupheleleyo ngerabha yendalo.I-Thermoplastic Vulcanizate (i-Thermoplastic Vulcanizate), ebizwa ngokuba yi-TPV
I-1, i-elasticity enhle kunye nokuxhatshazwa kwe-compression deformation, ukumelana nokusingqongileyo, ukuchasana nokuguga kufana nerabha ye-epDM, kwangaxeshanye ukuxhathisa kwayo kwe-oyile kunye nokumelana ne-solvent kunye ne-neoprene jikelele efanayo.I-2, uluhlu olubanzi lobushushu besicelo (-60-150 ℃), uluhlu olubanzi lwesicelo esithambileyo nesinzima (25A - 54D), iingenelo zokudaya ngokulula ziphucula kakhulu inkululeko yoyilo lwemveliso.I-3, ukusebenza kakuhle kokusebenza: inaliti ekhoyo, i-extrusion kunye nezinye iindlela zokusetyenzwa kwe-thermoplastic, iyasebenza, ilula, akukho mfuneko yokongeza izixhobo, umbane ophezulu, isantya esincinci sokucutheka.I-4, ukukhuselwa kokusingqongileyo okuluhlaza, ukuphinda kusetyenziswe, kunye nokusetyenziswa ngokuphindaphindiweyo kwamaxesha amathandathu ngaphandle kokuncipha okubonakalayo kokusebenza, ngokuhambelana neemfuno zokusingqongileyo ze-EU.I-5, ubunzima obuthile bulula (0.90 -- 0.97), umgangatho wembonakalo ufana, umgangatho ophezulu uphezulu, ukuvakalelwa kulungile.Ngokusekelwe kwiimpawu zokusebenza ezingentla, i-TPV isetyenziswa ngokubanzi kuluhlu olubanzi lwezicelo kunye nezixhobo zerabha zendabuko.Okwangoku, ezinye iimveliso zomtya wokutywina wemoto zithatyathelwa indawo yi-TPV yerabha ye-thermoplastic vulcanized nge-EPDM.I-TPV yerabha ye-thermoplastic vulcanized ineengenelo ezithile ezizezinye ekusebenzeni okubanzi kunye neendleko ezibanzi.
