Mizinda yambiri imagwiritsabe ntchito njira zamadzi zomwe zidakhazikitsidwa zaka makumi angapo zapitazo zomwe zikupitilizabe kuchita bwino, kuwonetsa kutalika kwa zinthuzo.
Kodi kutentha kumakhudza bwanji chitsulo cha ductile?
Chitsulo chachitsulo chimagwira ntchito bwino pa kutentha kwakukulu. Magulu a Ferritic amakhalabe olimba kukana ngakhale kutentha kwapansi pa zero, kuwapangitsa kukhala oyenera kumadera ozizira. Komabe, pa kutentha kwambiri (pamwamba pa 400 ° C), mphamvu zamakina zimatha kuwonongeka, ndipo kuchuluka kwa okosijeni kumawonjezeka. Kwa ntchito zotentha kwambiri, magiredi apadera a alloyed kapena zida zina zitha kufunikira.
Nchifukwa chiyani amatchedwa "ductile" ngati akadali mtundu wachitsulo chosungunuka?
Mawu oti "ductile" amatanthauza kuthekera kwake kosintha kwambiri pulasitiki isanadulidwe, chinthu chomwe nthawi zambiri chimasowa zitsulo zina zotayira ngati chitsulo chotuwira. Ngakhale mwaukadaulo ndi chitsulo chonyezimira chifukwa cha mpweya wake, mawonekedwe ozungulira a graphite amaupatsa mawonekedwe otalikirapo ofanana ndi chitsulo, motero amasiyanitsidwa ndi dzina.
Pomaliza ndi Njira Zotsatira
Kuponya kwachitsulo imayima monga mwala wapangodya wa zopangira zamakono, zomwe zimapereka mphamvu zosayerekezeka, kulimba, ndi kuyendetsa bwino chuma. Kuchokera pamapaipi amadzi pansi pa mizinda yathu kupita ku zida za injini zomwe zimayendetsa magalimoto athu, ntchito zake ndi zazikulu komanso zovuta. Pomvetsetsa magiredi osiyanasiyana, machulukidwe azomwe amapanga, komanso maubwino ake pazomwe zimapikisana, ogula amatha kupanga zisankho zanzeru zomwe zimakulitsa magwiridwe antchito komanso moyo wautali.
Nkhaniyi ndi yoyenera kwa mainjiniya ndi akatswiri ogula zinthu omwe akufuna mayankho amphamvu kwambiri popanda mtengo wamtengo wapatali wazitsulo zonyezimira. Ndizothandiza makamaka pamapulogalamu okhudzana ndi katundu wosunthika, kuletsa kupanikizika, komanso kukana kuvala. Kaya mukukweza zida zomwe zilipo kapena kupanga makina atsopano, chitsulo cha ductile chimapereka maziko odalirika kuti apambane.
Kuti mupite patsogolo, yang'anani zomwe mukufuna pulojekiti yanu yokhudzana ndi kuchuluka kwa katundu, kuwonekera kwa chilengedwe, ndi zovuta za bajeti. Dziwani ogulitsa omwe akuwonetsa ukatswiri waukadaulo komanso kuwongolera koyenera, monga mabwenzi okhazikika ngati QSY omwe amabweretsa zaka zambiri zapadziko lonse lapansi. Funsani mawu onyamulira mwatsatanetsatane omwe ali ndi certification ndikukambirana za kapangidwe kanu koyambirira ndi gulu lothandizira kuti mukonzekere kupanga. Kuchita izi kudzatsimikizira kuti mumagwiritsa ntchito mphamvu zonse zachitsulo cha ductile pulojekiti yotsatira.
