Mzere wosindikizira wamagalimoto (Khomo, zenera, kuwala kowala)
Mzere wosindikizira wagalimoto
Magalimoto osindikizira Mzere ndi chimodzi mwazinthu zofunika kwambiri, zomwe zimagwiritsidwa ntchito kwambiri pakhomo, zenera, thupi la galimoto, skylight, galimoto ya injini ndi bokosi (katundu) bokosi ndi zina, ndi zotsekemera zomveka, fumbi-umboni, madzi ndi damping ntchito, kusunga ndi kusunga yaing'ono. chilengedwe mkati mwa galimoto, kusewera galimoto okwera, zida zamagetsi ndi makina ndi zinthu ancillary chitetezo zofunika. Pakukula kwamakampani amagalimoto, kufunikira kwa kukongola, kutetezedwa kwa chilengedwe komanso ntchito yabwino yamizere yosindikizira ikukula kwambiri. SEALING SYSTEM (automo-bile SEALING SYSTEM) yoyikidwa m'malo osiyanasiyana agalimoto idafufuzidwa mwapadera ndikupangidwa m'makampani oyendetsa magalimoto akunja, ndipo kufunikira kwake kukukopa chidwi. 1. Malingana ndi dzina la magawo osindikizira (magawo), gululi limaphatikizapo: injini ya HOOD chisindikizo, ndipo ikhoza kugawidwa kutsogolo, mbali ndi kumbuyo; CHIZINDIKIRO CHA KHOMO; WINDOW zowonetsera kwa kutsogolo ndi kumbuyo mpweya Mawindo; Chisindikizo chawindo cha SIDE (chisindikizo chawindo cha SIDE); SUNROOF chisindikizo; CHISINDIKIZO CHACHIKHOMO CHOYAMBA; Mzere wosindikizira wa zenera lowongolera groove (GLASSRUN CHANNEL); Zingwe zamkati ndi zakunja (zodula madzi)(WAISTLINE); CHISINDIKIZO CHA THUNA; Mzere wosindikizira wotsutsa phokoso; Monga anti-fumbi. 2. Malinga ndi mawonekedwe a KUSINTHA, ikhoza kugawidwa mu WEATHERSTRIP seal ndi chisindikizo chamba. Pakati pawo, Mzere wosindikizira wa nyengo uli ndi chubu chopanda kanthu cha siponji, chomwe chimakhala ndi kutentha kwabwino komanso kusunga chinyezi. Zingwe zomata zomwe zimagwiritsidwa ntchito nthawi zambiri zimaphatikizapo chitseko chosindikizira, mizere yosindikiza masutikesi, chivundikiro cha chivundikiro cha injini, ndi zina zambiri. Zingwe zomata zomwe zimagwiritsidwa ntchito nthawi zambiri zimakhala kutsogolo ndi kumbuyo kwa mazenera osindikiza ndi zingwe zosindikizira zapakona, zamkati ndi zakunja, ndi zina zotero. kumagulu amtundu wa rabara, amatha kugawidwa mumzere wosindikizira wa rabara - wopangidwa ndi mphira umodzi; Mzere wosindikizira wamitundu iwiri - wopangidwa ndi guluu wandiweyani ndi guluu wa thovu, nthawi zambiri guluu wandiweyani molunjika kolowera komwe kumakhala ndi mafupa achitsulo; Chisindikizo chamagulu atatu - chimakhala ndi mitundu iwiri ya sealant (imodzi yomwe ndi yopepuka) ndi siponji yosindikizira, nthawi zambiri imakhala ndi mafupa achitsulo ndi ulusi wolimbitsa mkati mwa sealant. Zingwe zinayi zosindikizira - Shanghai Shenya Sealing parts Co., Ltd. idatsogola pakupanga ndi kupanga gulu losindikiza lopangidwa ndi mitundu 4 ya zida za mphira, pamwamba pa mphira (bubble chubu) ndikukutidwa ndi wosanjikiza wopyapyala. zomatira zoteteza zosanjikiza, kuti mupititse patsogolo moyo wautumiki wa zisindikizo. 4. Malinga ndi mtundu wa zinthu zakuthupi, zitha kugawidwa m'mizere yosindikiza mphira; Mzere wosindikizira wa pulasitiki; Thermoplastic elastomer seal strip. 5. Odziwika monga pamwamba mankhwala boma, ena kusindikiza Mzere pamwamba pambuyo mankhwala owonjezera, akhoza kugawidwa mu akukhamukira kusindikiza Mzere; Mzere wosindikiza wokutira pamwamba; Pali mizere yosindikizira ya nsalu. 6. Gulu lapadera la ntchito, Mzere wina wosindikiza uli ndi ntchito yanzeru yamagetsi, monga anti-clamping sealing strip.

Epdm mphira
Ethylene propylene diene diene (EPDM) imapangidwa ndi polymerization ya ethylene ndi propylene monomers ndi diolefin yaying'ono yopanda conjugated. Kapangidwe ka polima amadziwika ndi unsaturated zomangira awiri mu unyolo waukulu ndi unsaturated zomangira awiri mu unyolo nthambi. Chifukwa chake, ili ndi kukana kwanyengo yabwino, kukana kutentha, kukana kwa ozoni, kukana kwa UV komanso kuwongolera bwino komanso kutsika kwapang'onopang'ono kokhazikika, kotero ndizomwe zimakondedwa popanga mizere yosindikiza. Pakadali pano, zida zambiri zosindikizira zamagalimoto zikugwiritsa ntchito EPDM ngati zida zazikulu. Malingana ndi magawo osiyanasiyana ndi ntchito zazitsulo zosindikizira, pogwiritsira ntchito, vulcanization, chitetezo, kulimbikitsa, zipangizo zogwirira ntchito ndi zipangizo zapadera (monga colorant, thovu) zimawonjezeredwa ku zipangizo za EPDM kuti apange zomatira wandiweyani (kuphatikizapo zomatira zakuda). ndi zomatira zamitundu) ndi zomatira za siponji. Mzere wosindikizira wamagalimoto umapangidwa ndi kusungunuka kwabwino komanso kukana kupindika kwa kupsinjika, kukana kukalamba, ozoni, zochita zamankhwala, mitundu yosiyanasiyana ya kutentha (-40 ℃ ~ + 120 ℃) EPDM thovu labala ndi wandiweyani, wokhala ndi chitsulo chapadera. ndi lilime chomangira, cholimba, zosavuta kukhazikitsa. Zakhala zikufanana ndi opanga magalimoto akuluakulu.
Mafotokozedwe azinthu
Kutentha kovomerezeka:
Zida za EPDM -40 °F -248 °F (-40 ℃ -120 ℃)
Zida zamkati zazitsulo: waya wachitsulo kapena pepala lachitsulo
Labala wachilengedwe
Raba zachilengedwe ndi mtundu wa polyisoprene monga chigawo chachikulu cha chilengedwe polima pawiri, molecular formula ndi (C5H8) N, 91% ~ 94% ya zigawo zake ndi rabara hydrocarbon (polyisoprene), enawo ndi mapuloteni, mafuta acid, phulusa, shuga. ndi zinthu zina zosakhala mphira. Labala wachilengedwe ndiye mphira wogwiritsidwa ntchito kwambiri. Chifukwa mphira wachilengedwe uli ndi mikhalidwe yambiri yakuthupi ndi mankhwala, makamaka kulimba kwake, kutsekemera, kudzipatula kwamadzi ndi pulasitiki ndi zinthu zina, ndipo, pambuyo pa chithandizo choyenera, chimakhalanso ndi kukana kwamafuta, kukana asidi, kukana kwa alkali, kukana kutentha, kukana kuzizira, kukana kupanikizika, kukana kuvala ndi zinthu zina zamtengo wapatali, kotero, zimakhala ndi ntchito zambiri. Mwachitsanzo, kugwiritsa ntchito nsapato za mvula tsiku ndi tsiku, matumba a madzi ofunda, zotanuka; Magolovesi a opaleshoni, machubu oika magazi, makondomu omwe amagwiritsidwa ntchito m'chipatala ndi zaumoyo; Mitundu yonse ya matayala omwe amagwiritsidwa ntchito poyendetsa; Malamba oyendetsa, malamba oyendetsa, magalavu osamva asidi ndi alkali kuti agwiritse ntchito mafakitale; ntchito ulimi ngalande ndi ulimi wothirira payipi, ammonia matumba; Mabaluni oyimba pofufuza zanyengo; Kusindikiza ndi zida shockproof zoyeserera zasayansi; ndege, akasinja, zida zankhondo ndi zophimba mpweya zomwe zimagwiritsidwa ntchito podzitchinjiriza; Ngakhale maroketi, ma satelayiti opangidwa ndi dziko lapansi ndi zouluka mumlengalenga ndi zinthu zina zapamwamba zasayansi ndi zaumisiri sizingasiyanitsidwe ndi mphira wachilengedwe. Pakali pano, padziko lapansi pali zinthu zoposa 70,000 zopangidwa ndi mphira wachilengedwe. Thermoplastic Vulcanizate (Thermoplastic Vulcanizate), yotchedwa TPV
1, elasticity yabwino ndi kukana mapindikidwe kukana, kukana chilengedwe, kukana kukalamba ndi ofanana ndi mphira epDM, nthawi yomweyo kukana mafuta ake ndi kukana zosungunulira ndi neoprene ambiri ofanana. 2, osiyanasiyana kutentha ntchito (-60-150 ℃), osiyanasiyana zofewa ndi zovuta ntchito (25A - 54D), ubwino wopaka utoto bwino kwambiri ufulu wa kupanga mankhwala. 3, kwambiri processing ntchito: kupezeka jekeseni, extrusion ndi zina thermoplastic processing njira processing, kothandiza, losavuta, palibe chifukwa kuwonjezera zida, high liquidity, yaing'ono shrinkage mlingo. 4, kuteteza zachilengedwe zobiriwira, zobwezeretsedwanso, komanso kugwiritsa ntchito mobwerezabwereza kasanu ndi kamodzi popanda kuchepa kwakukulu kwa magwiridwe antchito, mogwirizana ndi zofunikira zachilengedwe za EU. 5, mphamvu yokoka yeniyeni ndi yopepuka (0.90 - 0.97), mawonekedwe ake ndi ofanana, mawonekedwe apamwamba ndi apamwamba, kumva bwino. Kutengera ndi magwiridwe antchito omwe ali pamwambapa, TPV imagwiritsidwa ntchito kwambiri pamagwiritsidwe osiyanasiyana ndi zida zachikhalidwe za rabala. Pakadali pano, zinthu zina zamizere yosindikizira yamagalimoto zimasinthidwa ndi TPV ya mphira wopangidwa ndi thermoplastic vulcanized EPDM. TPV ya rabara ya thermoplastic vulcanized ili ndi maubwino ena pakuchita bwino komanso mtengo wokwanira.
