Kodi ma aloyi amkuwa ndi amkuwa ndi chiyani?

Bronze poyamba amatanthauzazitsulo zamkuwandi malata ngati chinthu chachikulu chowonjezera.Masiku ano, zosakaniza zonse zamkuwa kupatula mkuwa zimaphatikizidwa m'gulu la bronze, monga tin bronze, aluminium bronze, ndi beryllium bronze.Komanso ndi mwambo kugawa mkuwa m'magulu awiri: malata mkuwa ndi Wuxi bronze.Amagwiritsidwa ntchito kwambiri popanga zida zolimbana ndi dzimbiri komanso zosavala, monga manja a shaft, thrust bearing pads, ndi zina zambiri.Zomwe zimapezeka kwambiri ndi mkuwa wa aluminiyamu, mkuwa wotsogolera ndi mkuwa wa beryllium.Aluminiyamu mkuwa ali bwino dzimbiri kukana kuposa malata mkuwa, ndipo nthawi zambiri ntchito kupanga dzimbiri zosagwira ndi kuvala mbali, monga magiya, magiya nyongolotsi, bushings, etc. Beryllium mkuwa makamaka ntchito akasupe zofunika ndi mbali zotanuka, komanso contactors magetsi, maelekitirodi kwa makina kuwotcherera magetsi, mawotchi ndi mawotchi etc.

Njira zambiri zakhala zikugwiritsidwa ntchito pofuna kuteteza mkuwa, chofunikira kwambiri chomwe ndikupita patsogolo kwa kafukufuku ndi chitukuko pogwiritsa ntchito mitundu yosiyanasiyana ya corrosion inhibitors.Pakali pano, Japan ali ndi kafukufuku wochulukirachulukira pa luso mkuwa ndi mkuwa aloyi pamwamba chitetezo, makamaka mbali ya zipangizo zokongoletsa nyumba, ndipo akwaniritsa zambiri bwino.Ntchito zapakhomo makamaka zimayang'ana kwambiri pakupukuta komanso kuletsa kusinthika kwa zinthu zamkuwa, ndipo kupita patsogolo kwina kwachitikanso.

The ndondomeko otaya mkuwa ndi mkuwa aloyi pamwamba passivation ndi: degreasing - kutsuka madzi otentha - kuchapa madzi ozizira - pickling (anayikira hydrochloric acid kapena misa kachigawo 10%, firiji 30s) - kutsuka makina - amphamvu asidi kutsuka - kutsuka madzi - pamwamba wokonza (30-90g /LCrO3g/0pick-150-30) (112804 ndi gawo lalikulu la 10%) ->kutsuka-kudutsa-kutsuka-kuyanika.Mafilimu osayenerera amtundu wa mkuwa ndi mkuwa akhoza kuchotsedwa mwa kulowetsedwa mu njira ya H2S04 ndi kagawo kakang'ono ka 1,000, hydrochloric acid kapena 300g/L sodium hydroxide solution.
