Timagwiritsa ntchito makeke kuti tiwongolere luso lanu.Mukapitiliza kusakatula tsamba ili, mukuvomera kugwiritsa ntchito ma cookie.Zina Zowonjezera.
Mwachilengedwe chake, zida zomwe zimagwiritsidwa ntchito pachipatala zimayenera kutsata kapangidwe kake komanso kupanga.M'dziko lomwe likukhudzidwa kwambiri ndi milandu ndi kubwezera chilango chifukwa chovulala kapena kuwonongeka chifukwa cha zolakwika zachipatala, chirichonse chimene chimakhudza kapena kuchitidwa opaleshoni m'thupi la munthu chiyenera kugwira ntchito monga momwe anafunira ndipo sichiyenera kulephera..
Njira yopangira ndi kupanga zida zamankhwala ndi imodzi mwazinthu zovuta kwambiri za sayansi ndi zovuta zaumisiri zomwe ziyenera kuthetsedwa m'makampani azachipatala.Pokhala ndi machitidwe osiyanasiyana otere, zida zachipatala zimabwera m'mitundu yonse ndi kukula kwake kuti zigwire ntchito zosiyanasiyana, choncho asayansi ndi mainjiniya amagwiritsa ntchito zipangizo zosiyanasiyana kuti akwaniritse zofunikira zopanga mapangidwe.
Chitsulo chosapanga dzimbiri ndi chimodzi mwazinthu zomwe zimagwiritsidwa ntchito kwambiri popanga zida zamankhwala, makamaka zitsulo zosapanga dzimbiri 304.
Chitsulo chosapanga dzimbiri cha 304 chimadziwika padziko lonse lapansi ngati chimodzi mwazinthu zoyenera kwambiri popanga zida zamankhwala pazogwiritsa ntchito zosiyanasiyana.Ndipotu ndi zitsulo zosapanga dzimbiri zomwe zimagwiritsidwa ntchito kwambiri masiku ano.Palibe gulu lina lachitsulo chosapanga dzimbiri lomwe limapereka mawonekedwe osiyanasiyana, kumaliza ndi kugwiritsa ntchito.Zida za 304 zitsulo zosapanga dzimbiri zimapereka zinthu zapadera pamtengo wopikisana, zomwe zimawapanga kukhala chisankho chomveka pazida zamankhwala.
Kukana kwa dzimbiri komanso kutsika kwa kaboni ndi zinthu zazikulu zomwe zimapangitsa kuti zitsulo zosapanga 304 zikhale zoyenera pachipatala kuposa magiredi ena achitsulo chosapanga dzimbiri.Zipangizo zachipatala sizigwirizana ndi minofu ya thupi, zoyeretsera zomwe zimagwiritsidwa ntchito poziziritsa, komanso kuvala kolimba, kobwerezabwereza komwe zida zambiri zachipatala zimatengera, kutanthauza kuti Type 304 chitsulo chosapanga dzimbiri ndi chinthu choyenera kuchipatala, opaleshoni, komanso othandizira azachipatala.mapulogalamu., mwa ena.
Chitsulo chosapanga dzimbiri cha 304 sichamphamvu chokha komanso chosavuta kuchikonza ndipo chimatha kukokedwa mozama popanda kutsekereza, kupanga 304 kukhala yabwino popangira mbale, masinki, miphika ndi mitundu yosiyanasiyana yazotengera zamankhwala ndi zinthu zopanda kanthu.
Palinso mitundu yambiri yosiyanasiyana ya zitsulo zosapanga dzimbiri 304 zokhala ndi zida zotsogola zogwiritsa ntchito zinazake, monga mtundu wolemera wa 304L wa 304L pomwe ma welds amphamvu kwambiri amafunikira.Zida zachipatala zingagwiritse ntchito 304L kumene kuwotcherera kuyenera kupirira kugwedezeka kosalekeza, kupanikizika kosalekeza ndi / kapena kupindika, etc. 304L chitsulo chosapanga dzimbiri ndi chitsulo chotsika kwambiri cha kutentha, chomwe chikutanthauza kuti chingagwiritsidwe ntchito pa ntchito zomwe mankhwala ayenera kugwira ntchito pa kutentha kwambiri.kutentha.Pamalo owononga kwambiri, 304L imaperekanso kukana kwakukulu kwa dzimbiri la intergranular kusiyana ndi magiredi osapanga dzimbiri.
Kuphatikizika kwa mphamvu zotsika zokolola komanso kuthekera kwakukulu kotalikira kumatanthauza kuti chitsulo chosapanga dzimbiri cha Type 304 ndichoyenera kupanga mawonekedwe ovuta popanda kutsekereza.
Ngati chitsulo chosapanga dzimbiri cholimba kapena champhamvu chikufunika pazachipatala, 304 ikhoza kuumitsidwa ndi kuzizira.Zitsulo za 304 ndi 304L zikamathiridwa, zimakhala ndi ductile kwambiri ndipo zimatha kupangidwa mosavuta, kupindika, kujambulidwa mozama kapena kupangidwa.Komabe, 304 imaumitsa mwachangu ndipo ingafunike kuyimitsidwa kwina kuti ipititse patsogolo ductility kuti ipitirire.
304 chitsulo chosapanga dzimbiri chimagwiritsidwa ntchito kwambiri m'mafakitale osiyanasiyana komanso m'nyumba.M'makampani opanga zida zamankhwala, 304 imagwiritsidwa ntchito pomwe kukana kwa dzimbiri, mawonekedwe abwino, mphamvu, kulondola, kudalirika ndi ukhondo ndizofunikira kwambiri.
Kwa zitsulo zosapanga dzimbiri zopangira opaleshoni, magiredi apadera azitsulo zosapanga dzimbiri, 316 ndi 316L, amagwiritsidwa ntchito makamaka.Ndi ma alloying a chromium, faifi tambala ndi molybdenum, chitsulo chosapanga dzimbiri chimapereka zida za asayansi ndi maopaleshoni apadera komanso odalirika.
Chenjezo.Zimadziwika kuti nthawi zina chitetezo cha mthupi cha munthu chimachita molakwika (mocheka komanso mwadongosolo) kuzinthu za nickel muzitsulo zina zosapanga dzimbiri.Pankhaniyi, titaniyamu ingagwiritsidwe ntchito m'malo mwa chitsulo chosapanga dzimbiri.Komabe, Titanium imapereka yankho lokwera mtengo kwambiri.Nthawi zambiri, chitsulo chosapanga dzimbiri chimagwiritsidwa ntchito popanga ma implants akanthawi, pomwe titaniyamu yokwera mtengo ingagwiritsidwe ntchito pakuyika kosatha.
Mwachitsanzo, tebulo ili m'munsili likutchula zina zomwe zingagwiritsidwe ntchito pazida zachipatala zosapanga dzimbiri:
