Umtya wokutywina wemoto (Ucango, ifestile, isibhakabhaka)
Umtya wokutywina wemoto
Umtya wokutywina we-Automotive ungomnye wamacandelo abalulekileyo, asetyenziswa ngokubanzi emnyango, ifestile, umzimba wemoto, i-skylight, i-injini ye-injini kunye nokugcinwa (umthwalo) ibhokisi njl njl, kunye ne-insulation sound, uthuli-ubungqina, umsebenzi ongenamanzi kunye nomswakama, ukugcina nokugcina indawo encinci ngaphakathi kwemoto, ukudlala imoto ehlala kuyo, izixhobo zombane kunye nemishini 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; PRIMARY DOOR Itywina; Umcu wokutywina wegroove yesikhokelo sefestile (i-GLASSRUN CHANNEL); Imicu yangaphakathi nangaphandle (i-watercut)(WAISTLINE); ISIQINISO SESIQINISEKISO; 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 eqhelekileyo esetyenziswayo ibandakanya umcu wokutywina wesakhelo socango, umtya wokutywina wesutikheyisi, umtya wokutywina wecala le-injini, njl. njl Imicu emibini edityanisiweyo yokutywina -- yenziwe ngeglu eshinyeneyo kunye neglu egwebu olugwebu, ngokufuthi kwiglu eshinyeneyo kwicala le-axis equlethe imathiriyeli yesinyithi; Itywina elihlanganisiweyo kathathu - liqukethe iindidi ezimbini ze-sealant (enye yazo inombala okhanyayo) kunye ne-sponge sealant, ngokuqhelekileyo iqulethe i-metal skeleton kunye nemicu eqinisiweyo ngaphakathi kwe-sealant. Umcu wokutywina owenziwe ngezinto ezine ezihlanganisiweyo - iShanghai Shenya Seal parts Co., Ltd. ithathe inkekelo ekuphuhliseni nasekuveliseni umcu wokutywina odibeneyo owenziwe ngeentlobo ze-rubber ezi-4, kumphezulu werabha (i-bubble tube) kwaye ugqunywe ngomqolo obhityileyo we-adhesive layer, 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 yeentambo zokutywina, kwisicelo esisebenzayo, i-vulcanization, ukhuseleko, ukuqinisa, izixhobo zokusebenza zenkqubo kunye nezixhobo ezikhethekileyo ezinikezelweyo (ezifana nombala, i-agent agent) zongezwa kwizinto ze-EPDM ukwenza i-adhesive dense (kubandakanya i-adhesive emnyama kunye ne-adhesive color) kunye ne-sponge adhesive. Umcu wokutywina we-Automotive ikakhulukazi uqulunqwe ngu-elasticity elungileyo kunye nokumelana nokuguqulwa koxinzelelo, ukumelana nokwaluphala, i-ozone, isenzo sekhemikhali, uluhlu olubanzi lobushushu (-40 ℃ ~ + 120 ℃) I-EPDM igwebu lerabha kunye ne-composite eshinyeneyo, equlethe intsimbi eyodwa kunye nentsimbi yolwimi, ehlala ixesha elide, 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
I-rubber yendalo luhlobo lwe-polyisoprene njengeyona nto iphambili ye-polymer compound yendalo, i-molecular formula yi (C5H8) N, i-91% ~ 94% yamacandelo ayo i-rubber hydrocarbon (i-polyisoprene), enye i-protein, i-fatty acid, i-ash, iswekile kunye nezinye izinto ezingenayo irabha. Irabha yendalo yeyona isetyenziswa ngokubanzi irabha yenjongo jikelele. Ngenxa yokuba irabha yendalo inoluhlu lweempawu zomzimba kunye neekhemikhali, ngokukodwa ukomelela kwayo okugqwesileyo, ukugquma, ukwahlukaniswa kwamanzi kunye neplastiki kunye nezinye iimpawu, kwaye, emva konyango olufanelekileyo, inokumelana neoli, ukuxhathisa kwe-asidi, ukuxhathisa kwealkali, ukumelana nobushushu, ukumelana nokubanda, ukumelana noxinzelelo, ukuxhathisa ukunxiba kunye nezinye iipropati ezixabisekileyo, ngoko ke, inoluhlu 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.
