Umugqa wokuvala wezimoto (Umnyango, iwindi, ukukhanya kwesibhakabhaka)
Umugqa wokuvala wemoto
I-Automotive sealing strip ingenye yezingxenye ezibalulekile, ezisetshenziswa kakhulu emnyango, efasiteleni, emzimbeni wemoto, skylight, ikesi lenjini kanye nebhokisi (imithwalo) ibhokisi njll, elinokufakwa komsindo, lingangenwa uthuli, lingangeni manzi kanye nomsebenzi wokudambisa, gcina futhi ulondoloze okuncane. imvelo ngaphakathi emotweni, ukudlala umgibeli wemoto, imishini kagesi kanye nemishini kanye nezinto ezihambisanayo zokuvikela okubalulekile. Ngokuthuthuka kwemboni yezimoto, ukubaluleka kokuhle, ukuvikelwa kwemvelo kanye nomsebenzi onethezekile womugqa wokuvala kuya ngokuya kugqama. I-SEALING SYSTEM (i-auto-bile SEALING SYSTEM) efakwe ezingxenyeni ezihlukahlukene zemoto iye yacwaningwa ngokukhethekile futhi yathuthukiswa embonini yezimoto yangaphandle, futhi ukubaluleka kwayo kudonsa ukunakwa okukhulayo. 1. Ngokusho kwegama lezingxenye zokuvala (izingxenye), ukuhlukaniswa kuhlanganisa: injini ye-HOOD seal, futhi ingahlukaniswa ngaphambili, ohlangothini nangemuva; DOOR SEAL; I-WINDOW izikrini zeWindows air yangaphambili nangemuva; I-SIDE window seal (I-SIDE Window seal); SUNROOF uphawu; PRIMARY DOOR SEAL; Umugqa wokuvala we-groove yomhlahlandlela wewindi (I-GLASSRUN CHANNEL); Imicu yangaphakathi nangaphandle (i-watercut)(WAISTLINE); ISIVIVINYO ESIQINISEKISO; I-anti-noise sealing strip; Okufana nothuli. 2. Ngokwezici ze-SEALING, ingahlukaniswa ngophawu lwe-WEATHERSTRIP kanye nophawu olujwayelekile. Phakathi kwazo, umugqa wokuvala uphawu lwesimo sezulu ufakwe ishubhu ye-sponge bubble engenalutho, enokushisa okungcono nokugcinwa komswakama. Imichilo yokuvala yesimo sezulu evame ukusetshenziswa ihlanganisa umucu wokuvala uhlaka lomnyango, umugqa wokuvala ipotimende, umugqa wekhava yekesi lenjini, njll. Imichilo yokuvala ejwayelekile evame ukusetshenziswa iyimicu yokuvala yamafasitela ngaphambili nangemuva kanye nemicu yokuvala iwindi ekhona, imicu yangaphakathi nangaphandle, njll. 3. Ngokusho ekuhlukaniseni isakhiwo esiyinhlanganisela sento yerabha, ingahlukaniswa ibe umucu wokuvala wenjoloba omsulwa -- owenziwe ngerabha eyodwa; Imichilo emibili ehlanganisiwe yokuvala -- eyakhiwe ngeglue elicinene ne-foam glue, evamise ukuba kwiglue elicinene elibheke eksisi equkethe insimbi yohlaka lwamathambo; I-triple composite seal - iqukethe izinhlobo ezimbili ze-sealant (eyodwa enombala okhanyayo) kanye ne-sponge sealant, ngokuvamile equkethe uhlaka lwensimbi kanye nemicu eqinisiwe ngaphakathi kwe-sealant. Imicu emine eyinhlanganisela yokuvala - I-Shanghai Shenya Sealing parts Co., Ltd. ihole ekuthuthukisweni nasekukhiqizeni umucu oyinhlanganisela wokuvala owenziwe ngezinhlobo ezi-4 zezinto zenjoloba, endaweni yenjoloba (bubble tube) futhi embozwe ngongqimba oluncane lwensimbi. i-adhesive layer eyisivikelo, ukuze kuthuthukiswe impilo yesevisi yezimpawu. 4. Ngokohlobo lokuhlukaniswa kwezinto ezibonakalayo, zingahlukaniswa zibe umucu wokuvala irabha; Umugqa wokuvala wepulasitiki; I-Thermoplastic elastomer seal strip. 5. Ihlukaniswa ngokwesimo sokwelashwa okungaphezulu, indawo ethile yomugqa wokuvala uphawu ngemva kokwelashwa okwengeziwe, ingahlukaniswa ibe umucu wokuvala ogelezayo; Umucu wokuvala wokumboza ngaphezulu; Kukhona imichilo yophawu lwendwangu. 6. Ukuhlukaniswa komsebenzi okukhethekile, omunye umugqa wokuvala unomsebenzi okhaliphile we-elekthronikhi, njengomugqa wokuvala wokuvala i-clamping.
(2) impahla yomugqa wokuvala
Irabha ye-EPdm
I-Ethylene propylene diene diene (EPDM) ihlanganiswa nge-polymerization ye-ethylene kanye ne-propylene monomers ngenani elincane le-diolefin engahlanganisiwe. Isakhiwo se-polymer sibonakala ngezibopho eziphindwe kabili ezingagcwalisiwe eketangeni eliyinhloko kanye nezibopho eziphindwe kabili ezingagcwalisiwe ochungechungeni lwegatsha. Ngakho-ke, inokumelana nesimo sezulu esihle kakhulu, ukumelana nokushisa, ukumelana ne-ozone, umugqa wokumelana ne-uv kanye nokusebenza okuhle kokusebenza kanye nokucindezelwa okuphansi kwe-deformation unomphela, ngakho-ke iyinto ethandwayo yokukhiqiza imichilo yokuvala. Njengamanje, iningi lezinto ezisetshenziswayo zokuvala uphawu zezimoto zisebenzisa i-EPDM njengento eluhlaza eyinhloko. Ngokusho kwezingxenye ezihlukene kanye nemisebenzi yemigqa yokuvala, ekusebenzeni okungokoqobo, i-vulcanization, ukuvikelwa, ukuqinisa, izinto zesistimu yokusebenza kanye nezinto ezikhethekile ezinikeziwe (ezifana ne-colorant, i-ejenti egwebuzelayo) zengezwa ezintweni ze-EPDM ukuze zenze i-adhesive adhesive (kuhlanganise ne-adhesive emnyama. nokunamathela kombala) kanye nengcina yesipontshi. Umugqa wokuvala uphawu wezimoto uhlanganiswe ikakhulukazi nokunwebeka okuhle kanye nokumelana nokuguqulwa kokucindezelwa, ukumelana nokuguga, i-ozone, isenzo samakhemikhali, ububanzi obubanzi bezinga lokushisa (-40 ℃ ~ + 120 ℃) Igwebu lerabha le-EPDM kanye nenhlanganisela eminyene, equkethe into eyingqayizivele yensimbi. kanye nebhande lolimi, eliqinile, kulula ukulifaka. Sekuyisikhathi eside ifaniswe nabakhiqizi abakhulu bezimoto.
Imininingwane yomkhiqizo
Ibanga lokushisa elinconyiwe:
Izinto ze-EPDM -40 °F -248 °F (-40℃ -120 ℃)
Impahla yensimbi yangaphakathi: ucingo lwensimbi noma ishidi lensimbi
Irabha yemvelo
Irabha yemvelo iwuhlobo lwe-polyisoprene njengengxenye eyinhloko yenhlanganisela ye-polymer yemvelo, ifomula yamangqamuzana ithi (C5H8) N, 91% ~ 94% yezingxenye zayo i-rubber hydrocarbon (polyisoprene), enye enye iphrotheni, i-fatty acid, umlotha, ushukela. nezinye izinto ezingezona irabha. Irabha yemvelo iyona esetshenziswa kakhulu inhloso ejwayelekile yenjoloba. Ngenxa yokuthi irabha yemvelo inochungechunge lwezimpawu zomzimba namakhemikhali, ikakhulukazi ukuqina kwayo okuhle kakhulu, ukwahlukanisa, ukuhlukaniswa kwamanzi kanye nepulasitiki nezinye izici, futhi, ngemva kokwelashwa okufanele, futhi inokumelana namafutha, ukumelana ne-asidi, ukumelana ne-alkali, ukumelana nokushisa, ukumelana nokubanda, ukumelana nokucindezela, ukumelana nokugqoka nezinye izinto ezibalulekile, ngakho-ke, kunezinhlobonhlobo zokusetshenziswa. Isibonelo, ukusetshenziswa kwansuku zonke kwezicathulo zemvula, izikhwama zamanzi afudumele, i-elastic; Amagilavu odokotela abahlinzayo, amashubhu okumpontshelwa igazi, amakhondomu asetshenziswa emkhakheni wezokwelapha nezempilo; Zonke izinhlobo zamathayi asetshenziswa kwezokuthutha; Amabhande okuthutha, amabhande okuthutha, amagilavu amelana ne-asidi ne-alkali ukuze asetshenziswe ezimbonini; Ukusetshenziswa kwezolimo kwe-drainage kanye nepayipi lokunisela, izikhwama ze-ammonia; Amabhaluni anomsindo okuhlola isimo sezulu; Imishini yokubeka uphawu kanye ne-shockproof yokuhlolwa kwesayensi; Izindiza, amathangi, izikhali namamaski egesi asetshenziselwa ukuzivikela; Ngisho namarokhethi, amasathelayithi okwenziwa emhlabeni kanye nemikhumbi-mkhathi neminye imikhiqizo eyinkimbinkimbi yesayensi nezobuchwepheshe ayinakuhlukaniswa nenjoloba yemvelo. Njengamanje, kunezinto ezingaphezu kuka-70,000 emhlabeni ezenziwe ngokwengxenye noma ngokuphelele ngenjoloba yemvelo. I-Thermoplastic Vulcanizate (i-Thermoplastic Vulcanizate), ebizwa ngokuthi i-TPV
I-1, ukunwebeka okuhle nokumelana nokucindezelwa kwe-deformation, ukumelana kwemvelo, ukumelana nokuguga kulingana nenjoloba ye-epDM, ngesikhathi esifanayo ukumelana kwayo nowoyela nokumelana ne-solvent kanye ne-neoprene evamile efanayo. 2, ububanzi obubanzi bokushisa kwesicelo (-60-150 ℃), uhla olubanzi lwesicelo esithambile nesiqinile (25A - 54D), izinzuzo zokudaya kalula zithuthukisa kakhulu inkululeko yokuklama umkhiqizo. I-3, ukusebenza okuhle kakhulu kokucubungula: umjovo otholakalayo, i-extrusion kanye nezinye izindlela zokucubungula ze-thermoplastic, zisebenza kahle, zilula, asikho isidingo sokwengeza imishini, i-liquidity ephezulu, isilinganiso esincane sokuncipha. 4, ukuvikelwa kwemvelo okuluhlaza, okugaywa kabusha, nokusetshenziswa okuphindaphindiwe izikhathi eziyisithupha ngaphandle kokwehla okukhulu kokusebenza, ngokuhambisana nezidingo zemvelo ze-EU. 5, amandla adonsela phansi athile alula (0.90 -- 0.97), ikhwalithi yokubukeka iyunifomu, ibanga elingaphezulu liphezulu, umuzwa muhle. Ngokusekelwe kuzici zokusebenza ezingenhla, i-TPV isetshenziswa kabanzi ezinhlobonhlobo zezinhlelo zokusebenza ngezinto zenjoloba zendabuko. Njengamanje, eminye imikhiqizo yomugqa wokuvala uphawu wemoto ithathelwa indawo yi-TPV yerabha evuvukele ye-thermoplastic ene-EPDM. I-TPV yerabha ene-thermoplastic vulcanized inezinye izinzuzo ezithile ekusebenzeni okuphelele nezindleko eziphelele.
