Door gasket msika zomwe zikuchitika? 

Anthu akamafunsa za momwe msika wa gasket ukuyendera, nthawi zambiri amayembekezera mndandanda wazoyendetsa bwino: malamulo oyendetsera mphamvu zamagetsi, kuphatikiza nyumba mwanzeru, zatsopano zakuthupi. Izi sizolakwika, koma zimaphonya mawonekedwe - kusintha kwenikweni kumachitika pamaulendo a fakitale, ma prototypes olephera, ndi zokambirana zamitengo pagulu linalake la EPDM. Mchitidwewu si njira chabe; ndi kukangana pakati pa zomwe mwalingaliridwe zotheka ndi zomwe zimasindikiza chitseko m'nyengo yozizira ku Chicago kapena mvula yamkuntho ku Bangkok. Tiyeni tifufuze mu izo.

Masewera a Zinthu Zakuthupi Siwongokhudza Zolemba

Aliyense amalankhula za silicone ndi TPE m'malo mwa mphira wamba. Mapepala amtunduwo amatsimikizira. Koma m'malo mwake, kusintha kumakhala kosokoneza. Ndikukumbukira pulojekiti yomwe inali ndi wopanga zida zapakatikati yomwe ikufuna kupanga mzere wapamwamba kwambiri. Anapeza silicone yapamwamba kwambiri, yosasinthasintha gasket pakhomo kwa mafiriji. Mayesero anali angwiro. Kenako kupanga voliyumu kugunda. Nthawi yozungulira yozungulira inali 15% yotalikirapo kuposa EPDM yomwe adagwiritsa ntchito kale, kupha mphamvu yawo ya mzere. Mchitidwe wopita ku silikoni unayima chifukwa mtengo wathunthu wa kuwerengera umwini sunachitike patsogolo. Kodi tsopano? Sikuti ntchito zakuthupi zokha, koma kugwirizana kwa ndondomeko. Othandizira omwe amatha kupanga zisankho ndikuchiritsa mbiri akupambana.

Ndiye pali zobwezerezedwanso zomwe zili kukankha. Brands amafuna nkhani zokhazikika. Koma kupeza magwiridwe antchito osasinthika kuchokera kumagulu a raba omwe abwera pambuyo pa mafakitale kapena ogula ndizovuta. Ndawonapo magulu omwe kuponderezana kumasiyanasiyana mosiyanasiyana, zomwe zimatsogolera kulephera kwa chitseko pakatha chaka. Zochitika zenizeni pakati pa opanga zazikulu sizingopereka njira yobiriwira, koma kukhala ndi kuya kwaumisiri wapawiri kuti atsimikizire kugwira ntchito. Ndi mpikisano wabata, waukadaulo wa zida.

Apa ndipamene maziko a kampani amafunikira. Tengani wopanga ngati Malingaliro a kampani Handan Zitai Fastener Manufacturing Co., Ltd.. Kutengera ku Yongnian, pakatikati pamakampani othamanga kwambiri ku China, amawona kusintha kwazinthu kuchokera mbali ina. Ubwino wawo sikuti umangopanga gasket, koma pakuwongolera kutuluka konseko kuchokera ku stamping yachitsulo (kwa magulu ophatikizika a gasket-fastener) mpaka kuphatikizika kwa mphira. Kwa iwo, njira yopita ku mayankho ophatikizana osindikizira ndimasewera achilengedwe. Malo omwe ali pafupi ndi misewu yayikulu ngati Beijing-Guangzhou Railway amatanthauza kuti amatha kutsata madongosolo anthawi yake, osakanikirana omwe amafunikira misonkhano yovutayi. Ndilo kuyankha kothandiza kumayendedwe.

Smart Seal Hype ndi Zowona

Kuphatikiza masensa mu ma gaskets kuti azindikire kulephera kwa chisindikizo kapena kutulutsa mphamvu ndi nkhani yovuta kwambiri. Zikumveka ngati zam'tsogolo. Koma kuchokera kumalingaliro opanga, ndi mutu wodalirika. Tinayesa chitsanzo chokhala ndi inki yosindikizidwa pamlomo wa gasket. Zinagwira ntchito-mpaka zinayang'anizana ndi condensation ndi kuyendetsa njinga zamoto. Zalephera mkati mwa miyezi. Mchitidwewu sikuti umakhudza kupanga gasket kompyuta; ndizokhudza kuzipanga kukhala zogwirizana ndi imodzi. Zomwe zimapatsa chiyembekezo komanso zosawoneka bwino ndizopangidwa ndi gasket zomwe zimagwira ntchito bwino ndi zowonera pazitseko zosiyana, zolimba - kupanga dongosolo lanzeru, osati lanzeru lomwe silingalephereke.

Kufufuza kwina kwenikweni: mtengo. Msika wa zida zamagetsi ukupikisana mwankhanza. Kuonjezapo mtengo wa dola ku a chisindikizo cha khomo pazinthu zanzeru ndizosayambitsa 80% ya voliyumu. Zatsopano zenizeni zili m'mapangidwe ang'onoang'ono - ma geometri omwe amapangitsa kuti chisindikizo chikhale cholimba kwambiri kotero kuti amachepetsa mtolo pa makina oziziritsa, mopanda mwachindunji kuthandiza mphamvu zonse za chipangizocho. Izi ndizomwe zimachitika ndi mano: nzeru zamapangidwe, osati nzeru zamagetsi.

Kugawaniza Magawo a Supply Chains

Mliri ndi mikangano yazandale sizinangosokoneza maunyolo operekera; iwo anasintha filosofi ya kamangidwe. Mchitidwewu ndi wopita ku malo operekera zakudya m'madera. Sikulinso za kupeza gwero limodzi lotsika mtengo m'dziko limodzi. Kwa opanga uvuni ku Europe, zitha kutanthauza kutulutsa ma gaskets kuchokera Kum'mawa kwa Europe kapena Kumpoto kwa Africa m'malo mwa Asia, ngakhale pamtengo wa 5-10%. Kuwerengera kumaphatikizapo katundu, ntchito, ndi zoopsa.

Uku ndikukonzanso zoyembekeza zabwino. Wogulitsa gasket ku Mexico yemwe akugwira ntchito pamsika waku US tsopano akuyenera kukwaniritsa osati zongogwira ntchito, koma zolemba zenizeni, kuyika, ndi ndondomeko zamakampani a Just-In-Time ku Ohio. Cholepheretsa kulowa ndi chapamwamba, koma makontrakitala ndiomata. Mchitidwewu uli pa maubale ozama, ogwirizana kwambiri ndi ogulitsa, osati kungogula kokha.

Makampani omwe ali m'malo akuluakulu a Logistics akusintha. Wopanga ngati Zitai Fastener, moyandikana ndi National Highway 107 ndi Beijing-Shenzhen Expressway, adapangidwira izi. Zawo webusayiti ikuwonetsa masikelo awo opanga ndi maulalo amayendedwe - malo ogulitsira tsopano. Kwa wogula wapadziko lonse lapansi, sizongokhudza luso lawo lofulumira, koma za kuthekera kwawo kokhala ngati malo odalirika mkati mwa gawo lachigawo cha Asia pamisonkhano yovuta yosindikiza.

Zoyembekeza Zochita Pamikhalidwe Yambiri

Lankhulani ndi mainjiniya aliwonse mu HVAC kapena gawo lafiriji lazamalonda. Zomwe zikuchitika sizokhudza zolemba zapamwamba pamapepala; ndi za kukhazikika kokulirapo pansi pamikhalidwe yosinthika. Malo osungiramo data ku Middle East, kusungirako kozizira kokhazikika m'madoko - mapulogalamuwa amakankhira gaskets kupitirira machitidwe oyesera. Njira yolephereka nthawi zambiri imayikidwa pansi pa kutentha kwakukulu, pakamwa kutanthauza kuti gasket sibwereranso.

Tikuwona kufunikira kowonjezereka kwa kutsimikizika kophatikizika kokhazikika. Sikokwanira kunena kuti EPDM iyi ndi yabwino ku 125 ° C. Otsatsa amayenera kupereka deta yoyeserera kuchokera pamisonkhano yeniyeni yapakhomo pansi pamikhalidwe yozungulira. Izi zimakankhira mayendedwe opita ku engineering ya application. Otsatsa abwino kwambiri akumanga zipinda zazing'ono zoyesera zomwe zimatengera zomwe makasitomala amakumana nazo. Ndizowonjezera mtengo zomwe zimapambana bizinesi.

Izi zikugwirizana ndi sayansi ya zinthu. Pali kuyang'ananso kwatsopano pazowonjezera - msuzi wachinsinsi mumagulu a rabara omwe amalimbana ndi ozone, UV, ndi kutentha kwambiri. Zatsopano pano sizowoneka koma zovuta. Ndizochitika zomwe zimayendetsedwa ndi zolephera zam'munda, osati malonda.

Chonyalanyazidwa: Kuyika ndi Kulekerera

Gasket yabwino imatha kulephera ngati chimango cha chitseko chomwe chimakhalapo sichili. Kulekerera kwa chipangizo chamagetsi kapena chitseko chomangira ndi chinthu chachikulu, chomwe nthawi zambiri chimanyalanyazidwa. Zomwe ndikuwona ndikusunthira ku mapangidwe okhululuka a gasket - mbiri yapawiri-kachulukidwe, kapena mapangidwe okhala ndi mitundu yosindikiza yotakata. Zitha kukhala zotsika mtengo pazinthu zakuthupi, koma zimachepetsa zonena za chitsimikizo kwambiri.

Izi zimafuna mgwirizano wapamtima. Njira yakale inali kutumiza gasket spec kwa ogulitsa atatu ndikusankha otsika mtengo. Njira yatsopanoyi ikuphatikizapo kugawana zitsanzo za CAD za msonkhano wa pakhomo ndikuyendetsa mafanizidwe a FEA pa kusindikiza kwa chisindikizo. Ndi luso, ndi pang'onopang'ono, koma amaletsa masoka. Otsatsa omwe atha kuchita nawo gawoli akulekana ndi paketi.

Zimasinthanso zomwe tikutanthauza ndi khalidwe. Sikulinso za gawo lakuthupi, koma za chithandizo chaukadaulo ndi mgwirizano wamapangidwe kumbuyo kwake. Msika ukugawika m'magulu ogulitsa gasket ndi othandizira mainjiniya. Kumapetoko ndi kumene malire ndi zochitika za nthawi yayitali zikupita.

Ndiye kodi izi zikutisiya kuti? The khomo gasket msika mayendedwe akutembenukira pa kuphatikiza, kulimba mtima, ndi mgwirizano wozama waukadaulo. Ndizochepera pazatsopano zamatsenga komanso zambiri zakuchita zoyambira bwino m'dziko lovuta kwambiri, lachigawo, komanso lovuta. Otsatsa omwe adzapindule ndi omwe amamvetsetsa kuti mankhwala awo si mphira chabe-ndi gawo lofunika kwambiri mu dongosolo lomwe kulephera kwake kumawonekera nthawi yomweyo kwa wogwiritsa ntchito mapeto. Ndicho chitsenderezo chenicheni, ndi chikhalidwe chenichenicho.
