Msika wa Rubber gasket? 

Kuwona Kuchokera Pansi

Aliyense akulankhula za momwe msika ukuyendera, koma theka la zolosera zomwe mumawerenga zimamveka kuti zasokonekera pashopu. Kusintha kwenikweni sikuli m'malipoti; ali m'mapepala omwe amatera pa desiki langa, zitsanzo zolephera zomwe timathetsa, komanso kufulumira kwadzidzidzi kwa kasitomala za kulephera kusindikiza m'malo onyowa, am'mphepete mwa nyanja. Ndizochepa pa nkhani zazikulu komanso zambiri za zokwawa, zofunikira zenizeni mphira gasket ntchito.

Kusintha Kwazinthu Sikuti Ndi Buzzword Yake

Kwa zaka zambiri, EPDM ndi Nitrile anali mafumu opita kwa mafumu. Zodalirika, zomveka, zotsika mtengo. Koma chitsenderezo chikubwera kuchokera kumbali zonse tsopano. Sichimangokhudza kutentha kapena kukana mafuta. Ndikuwona ma RFQ ochulukirapo akuwonetsa kutsika kwa VOC kapena akufunika kutsatiridwa ndi mfundo za FDA kapena USP Class VI pazotsekera m'nyumba zazida zamankhwala. Gawo la silikoni likukulirakulirabe, koma ngakhale likugawika - silikoni yokhazikika kwambiri m'malo ovuta kwambiri motsutsana ndi rabara yamadzimadzi ya silicone yamagetsi ovuta, opanda flash mumagetsi ogula.

Kukankhira motsutsana ndi mankhwala a PFAS ndi chitsanzo cha konkire. Tidakhala ndi projekiti ya kasitomala wamagalimoto aku Germany chaka chatha pomwe mapangidwe oyamba adagwiritsa ntchito gasket ya fluoroelastomer FKM pagawo lamafuta. Zomwe zidakumana nazo zonse zaukadaulo, koma zidabweranso ndikulamula njira ina yopanda PFAS chifukwa cha malamulo omwe akubwera. Tinakhala miyezi itatu tikuyesa ma acrylics osinthidwa komanso zosakanikirana za nitrile zodzaza kwambiri. Kulephera sikunali kuyesa kwa labu, koma kupsinjika kwa nthawi yayitali komwe kumayikidwa pansi pa njinga yamoto. Tinafika kumeneko, koma mtengo wa gawo lililonse unalumpha 22%. Izi ndizochitika zenizeni: sayansi yakuthupi ikuyendetsedwa ndi chemistry yolamulira monga momwe uinjiniya.

Ndipo imapanga ma niches odabwitsa. Ndikukumbukira wogulitsa, Handan Zitai Fastener Manufacturing Co., Ltd., yemwe ali mu gawo lalikulu la magawo ku Yongnian, Hebei. Amadziwika ndi zomangira, koma mayendedwe awo popereka magulu ophatikizika a fastener-gasket (monga washer-gasket) amamveka. Imalankhula za kufunikira kwa njira zosindikizira zophatikizika zomwe zimathandizira kuphatikiza. Malo omwe ali pafupi ndi mayendedwe akuluakulu monga Beijing-Guangzhou Railway mwina amawathandiza kuti asamawononge ndalama pamagulu ophatikizikawa, omwe ndi theka lankhondo.

Kulondola Sikulinso Kwamba

Kulekerera kumatanthawuza +/- 0.5mm. Tsopano, pa chilichonse chopangira magetsi pamagalimoto kapena zida zolondola, tikulankhula +/- 0.1mm kapena zothina. Zomwe zikuchitika sizingokhudza chiwerengero; zimatengera kusasinthika pakupanga mayunitsi 500,000. Gasket ya mbale yoziziritsira batire yomwe yatsika ndi magawo khumi a millimeter sangangogwedezeka kuti isindikize. Zimapanga malo otentha otentha.

Apa ndi pamene mayendedwe amsika kugunda zenizeni zopanga. Kumangirira kolimba kumakhala kofunikira kwambiri pamawonekedwe apamwamba, osavuta, koma tikuwonetsa zambiri ndikudula bwino kuchokera pamapepala a kalendala ndipo, mochulukira, kudula kwa waterjet kwa ma prototype otsika, ovuta. Mtengo wa zida za nkhungu yojambulira jekeseni wovuta ukhoza kukhala wolepheretsa kuyambitsa kwatsopano. Ndawonapo ma projekiti akuyimilira chifukwa cha ndalama zopangira zinthu zapadera mphira gasket adachotsa malire a phindu kwa zaka ziwiri zoyamba zogulitsa.

Kuyesera kulephera? Nthawi ina tidayesa kugwiritsa ntchito rabara yotsika mtengo, ya siponji yokhala ndi chikopa kuti tikwaniritse zomwe tikufuna kusindikiza komanso mtengo wa kabati yakunja ya telecom. Idapambana mayeso oyamba a IP67. Koma patangotha ​​nyengo imodzi, chinkhupulecho chinatenga chinyezi, n’kuundana, n’kugwetsa selo. Chisindikizocho chinalephera kwambiri. Phunzirolo linali lankhanza: kulondola kumatanthauzanso kumvetsetsa bwino kwa chilengedwe chonse, osati kuyesa kuvomereza fakitale.

Kukwera Kwachete kwa Mapangidwe a Serviceability

Ichi ndi dalaivala wochenjera koma wamphamvu. M'makina opanga mafakitale makamaka mu mapaketi a batri a EV, ma gaskets salinso oyenera ndikuyiwala. Ayenera kusindikiza bwino kwa zaka komanso kulola kuti asawononge osawononga kuti akonze kapena kusintha ma cell. Izi zikupha zida zambiri zomatira zomata kapena zochiritsika.

Tikuwona mapangidwe ambiri omwe amayitanitsa mbiri zosindikizira zomwe zingagwiritsidwenso ntchito ndi kukakamiza koyendetsedwa, monga mawonekedwe a D kapena zisindikizo zopanda pake zomwe zili ndi malo ogwa. Zinthuzo zimafunikira kupsinjika kochepa, inde, komanso mphamvu yabwino yong'ambika komanso kukana kugwedezeka panthawi ya disassembly. Ndizinthu zina zofunika kwambiri. Makasitomala mu gawo la HVAC amafuna gasket yanyumba yosefera yomwe imatha kuchotsedwa ndikukhazikitsidwanso nthawi zosachepera makumi asanu popanda kutayikira. Tinamaliza ndi EPDM yowirira, yotsekedwa yokhala ndi khungu lopangidwa mwapadera. Zinagwira ntchito, koma chitukukochi chinali chobwerezabwereza, chodzazidwa ndi kuyesa ndi kusintha kwa malo.

Izi zikugwirizananso ndi mtengo wathunthu wa umwini, zomwe ndizomwe mainjiniya akuyezedwa pano. Si gasket yotsika mtengo kwambiri, koma yomwe siyikakamiza kutsitsa makina a $ 5,000 kuti mulowe m'malo mwa $ 5.

Supply Chain Zowona Zopanga Zosankha

Kusokonezeka kwa nthawi ya mliri sikunathe kwenikweni; iwo anangosintha mawonekedwe. Nthawi zotsogola zopangira zida zamtundu wakuda wakuda kapena zochizira platinamu zimathabe kugwedezeka. Izi zapangitsa kuti zinthu zapawiri kapena zovomerezeka zisinthe kukhala gawo lofunikira kwambiri. Ndikuthera nthawi yochulukirapo ndikukonzekeretsa banja lazinthu la Plan B pamodzi ndi chisankho choyambirira.

Izi zimakonda opanga zazikulu, zophatikizika ndikuyika kukakamiza kwa masitolo ang'onoang'ono. Zimabweretsanso makampani monga Handan Zitai omwe tawatchulawa muzokambirana mosiyana. Kwa chomangira chokhazikika chokhala ndi chochapira chosavuta cha rabara, mtundu wawo wopangira ma voliyumu apamwamba kwambiri (kuyandikira kwawo ku National Highway 107 ndi Beijing-Shenzhen Expressway ndi mwayi wovomerezeka) utha kukhala wotsimikiza. Koma pamwambo, njira yosindikizira yopangidwa mwaluso, malo amafunikira zochepa kuposa mgwirizano waukadaulo. The msika ili ndi magawo awiri: zosindikizira ngati zamalonda motsutsana ndi zida zopangidwa kwambiri.

Chiwopsezo tsopano ndikusiyana mopitilira muyeso. Kuyesa kusunga magiredi ochulukirapo kuti muthe kulabadira kumatha kupha kutuluka kwa ndalama. Taphunzira kuyang'ana kwambiri pachimake cha mabanja pafupifupi asanu ndi atatu a polima omwe timawadziwa mkati, ndikugwirizana kwambiri ndi ophatikiza ochepa odalirika pazinthu zachilendo. Ndi za kuya, osati m'lifupi chabe.

Kumene Smart Hype Imakwaniritsa Zofunikira

Masensa ophatikizidwa mu gaskets? Nthawi zambiri akadali zinthu za lab. Nzeru zenizeni zili mu kamangidwe ndi kufufuza deta. Ndikulankhula za ma gaskets okhala ndi ma QR codes laser-okhazikika pamwamba omwe amabwerera ku gulu lenileni la pawiri, machiritso magawo, ndi satifiketi ya QA. Izi zikukhala muyezo wamagalimoto amtundu wamagalimoto ndi ndege. Ndi kuyankha kuudindo komanso kutsatiridwa bwino, osati chinyengo.

Njira yothandiza kwambiri yanzeru ndiyo kulephera kulosera. Pomvetsetsa kuchuluka kwa ma compression, ma curve okalamba otenthetsera, komanso kuyanjana kwazinthu zina gasket kupanga, tsopano titha kutengera moyo wake wautumiki womwe ukuyembekezeka mu mapasa a digito a msonkhano. Izi zimalola makasitomala kusuntha kuchoka pakukonzekera nthawi kupita kutengera momwe zinthu ziliri. Sizowoneka bwino, koma zimapulumutsa mamiliyoni mu nthawi yosakonzekera.

Chifukwa chake, ndikaganizira zomwe zikuchitika, ndimaganiza zocheperako pamzere wokulirapo pa graph ndi zina mwazomwe zasonkhanitsidwa, zokakamiza za granular: chemistry yowongolera, kulolerana kwapang'ono, kufunidwa kwa serviceability, ma buffer chain, ndi kutsatiridwa kwa data. Gasket ya rabara si chidutswa cha mphira panonso; ndi gawo lolondola lopangidwa ndi polima lomwe limatanthauzidwa ndi chilengedwe chake chonse. Msikawu ukukakamiza aliyense kumtunda, kuyambira kophatikiza mpaka wopanga makina mpaka wogawa. Iwo omwe amakhala mu malingaliro azinthu zazachuma adzapanikizidwa. Ena onse ali otanganidwa mu labu, pa atolankhani, ndi pa foni, kulingalira chitsanzo chimodzi cholephera ndi chisindikizo chimodzi chopambana panthawi imodzi.
