Chiyambi
Mbele, chuma chosintha chomwe chimagwiritsidwa ntchito kwambiri m'makampani, chimakhala ndi vuto lachilengedwe lomwe lingakhudze kwambiri machitidwe ake. Zodabwitsazi ndizofunikira kuti mumvetsetse, chifukwa zimakhudza mwachindunji kukhazikika komanso kumagwiridwera kwa zinthu za mphira zomwe zimagwiritsidwa ntchito kuchokera ku Aerospace. Njira yokalambayo imakhudzidwa ndi zinthu zosiyanasiyana, kuphatikizapo nyengo zachilengedwe, kuwonekera kwa mankhwala, kuwonekera kwamakina. Mwa kudzipereka m'mavuto a mwana wa mphira, titha kupanga njira zochepetsera mavuto ake ndikuwonjezera moyo wachuma. Kusanthula kwakuya kwapamwamba kwa ntchito zosiyanasiyana za mphira, kuchezera Labala.
Kumvetsetsa ukalamba
Kusintha kwa mankhwala ndi thupi
Kukalamba kwa mphira kumadziwika ndi kusintha kwa thupi komanso thupi. Mankhwala, oxidation, hydrolysis, ndi kulumikizidwa kodutsa ndizofala zomwe zimasintha kapangidwe ka mphira. Kusintha kumeneku kumatha kusokoneza, kusokonekera, kapena kutaya thupi. Mwakuthupi, zinthuzo zitha kuwonetsa kuwonongeka kwa pamtunda, kupukutira kwamphamvu, komanso kuchepetsedwa kwamphamvu. Kuzindikira kusintha kumeneku ndikofunikira polosera za moyo wa rabasi ndi zida zopanga zikuluzikulu.
Zochitika Zachilengedwe
Zinthu zachilengedwe zimasewera gawo lofunika kwambiri. Kuwonetsedwa ku Ultraviolet (UV) radiation, ozone, ndi kutentha kwambiri kumathandizira kukonzanso. Ma radiation ya UV imaphwanya unyolo wa polymer, zomwe zimapangitsa kuti nthaka ikhale ndi blitle. Ozone, gasi wogwira bwino ntchito, amaukira maubale awiri mu mphira, ndikuyambitsa ming'alu kuti apatsidwe nkhawa. Kutentha kwambiri kumatha kukulitsa zotsatirazi ndikuwonjezera kuchuluka kwa zochita za mankhwala. Pothana ndi izi, opanga nthawi zambiri amaphatikizira okhazikika ndi antioxidants m'mafupa a mphira.
Makina Opsinjika
Kupsinjika kwamakina, kuphatikiza kutambasula, kukakamira, ndi abrasion, kumathandizira kukalamba kwa mphira. Kubwerezedwa mobwerezabwereza kumatha kutopa, kumapangitsa kuti ming'alu yaying'ono ikhale yolephera. Kutanthauzira pakati pa kupsinjika kwamakina ndi zinthu zachilengedwe, kuwonekera kwa a Ozoni, kumathandiziranso kukalamba. Akatswiri amalinjiniya ayenera kuganizira zinthuzi popanga zigawo za mphira zokakamiza zofunsira, monga matayala okha ndi zisindikizo za mafakitale.
Njira zochepetsera ukalamba wa mphira
Kusankha Zinthu
Kusankha mtundu woyenera wa mphira ndikofunikira kuti muchepetse ukalamba. Opanga opaleshoni, monga Ethylene Pronsomene Womene Worder (EPDM) ndi fluoroelastomers, amaperekanso kukana kwakukulu kwa zinthu zachilengedwe poyerekeza ndi chilengedwe. Zipangizozi nthawi zambiri zimagwiritsidwa ntchito poizoni zomwe zimafuna kulimba kwambiri komanso kugwiritsa ntchito mankhwala. Kuti mumve zambiri pa EPDM's VDTICTION ya EPDM, funafunani Labala.
Zowonjezera ndi zowonjezera
Kuphatikiza zowonjezera ndi zolimbitsa thupi kulowa mu mphira za mphira zimatha kupititsa patsogolo kukana kwawo kukalamba. Antioxidants amalepheretsa kuwonongeka kwa oxida posintha ma radicals aulere, pomwe omaliza a UV a UV amatenga ma radiation ovulaza. Makonda mafilimu, monga kaboni wakuda ndi silica, kusintha zinthu zamakina ndikuchepetsa mphamvu ya kupsinjika kwachilengedwe. Izi zowonjezerazi zimagwirizana ndi ntchito zapadera kuti zitheke ndi moyo wautali.
Zoteteza
Kugwiritsa ntchito zokutira zoteteza ndi njira ina yogwira mtima kuti muchepetse ukalamba wa mphira. Zophatikiza kukhala ngati zopinga zotsutsana ndi radiation ya UV, ozone, ndi kuwonekera kwa mankhwala, kukulitsa moyo wamoyoyo. Mwachitsanzo, silika ozikidwa padokoni, amagwiritsidwa ntchito kwambiri pamapulogalamu aomwetive ndi awespace chifukwa chokana kwambiri ndi kukhazikika kwawo. Zovala izi ndizopindulitsa makamaka pazigawo za mphira zomwe zimadziwika m'malo ovuta.
Kafukufuku ndi mapulogalamu
Makampani Oyendetsa Magalimoto
Makampani ogulitsa magalimoto amadalira kwambiri mphira wa zigawo monga matayala, Zisindikizo, ndi hoses. Opukutira osagonjetsedwa, monga Epdm ndi fluorostomer, nthawi zambiri amagwiritsidwa ntchito kuwonetsetsa kuti zikhalepo komanso kugwira ntchito. Mwachitsanzo, Epdm amakomera chifukwa chokana kwambiri kutentha, ozone, komanso nyengo, ndikupanga zigwirizane ndi zisindikizo zaokha ndi ma gaskets. Kuti mudziwe zambiri za mapulogalamu a EPDM, pitani Labala.
Ntchito za Aerospace
Mu amoskos, zigawo zikuluzikulu za mphira ziyenera kupirira zolimba, kuphatikizapo madera okwera, kusinthasintha kwa kutentha, komanso kuwonekera kwa ozone. Fluoroelastomers amagwiritsidwa ntchito popanga mafakitaleyi chifukwa chokana kwawo kukalamba ndi kuwonongeka kwa mankhwala. Zipangizozi ndizofunikira kuti zisindikizo, ma gaskets, ndi hoses mu ndege ndi sparkraft, ndikuwonetsetsa chitetezo komanso kudalirika.
Makina ogulitsa
Rabab ndi nkhani yovuta kwambiri m'makina ogulitsa mafakitale, pomwe imagwiritsidwa ntchito ndi malamba, hoses, ndi kugwedezeka. Njira yokalambayo ingathe kusiya magwiridwe antchito awa, zomwe zimayambitsa zida zolephera komanso nthawi yopuma. Mwa kusankha oponya okalamba komanso kuphatikiza njira zotchinga, opanga amatha kukulitsa kudalirika komanso kugwiritsa ntchito makina makina.
Mapeto
Njira yokalambayo ya mphira ndi zovuta zovuta zomwe anachita pogwiritsa ntchito mankhwala, mwakuthupi, komanso zachilengedwe. Kuzindikira njirazi ndikofunikira pakupanga njira zothandizira kulimbitsa thupi ndi ntchito. Posankha zinthu zoyenera, kuphatikiza zowonjezera, komanso kugwiritsa ntchito zokutira zoteteza, opanga amatha kuchepetsa mavuto obwera chifukwa cha ukalamba ndikuwonjezera zinthu zomwe ndimtunda wa mphira. Kuti muzindikirenso kuchuluka kwa mphira ndi mapulogalamu ndi ntchito, onani Labala.
