Mbiri Yamakampani: Zovuta Zachilengedwe Pamafakitale mpaka Magudumu Amanja a Valve
Popanga mankhwala, mankhwala osiyanasiyana owononga dzimbiri nthawi zambiri amayenda kudzera m'mavavu, monga chlorine ndi caustic soda m'makampani a chlor-alkali, ndi ma sulfides poyenga petroleum, zomwe zimachititsa kuti mavavu azitha kudwala kwambiri. Pankhani ya uinjiniya wa m'madzi, kutentha kwambiri-kwakuchuluka kwa mchere komanso chinyezi chambiri-kumadzi a m'nyanja ya m'nyanja kumapangitsa kuti mawilo a m'manja awonongeke ndi electrochemical, zomwe zimapangitsa kuti mawilo a m'manja achepe kapena kulephera kugwira bwino ntchito. Malinga ndi ziwerengero, kulephera kwa zida zomwe zimachitika chifukwa cha dzimbiri za ma valve oyendetsa manja kumabweretsa mabiliyoni a madola pakuwonongeka kwachuma kumakampani apadziko lonse lapansi chaka chilichonse.
Core Factors Aaffect the Anti-corrosion Performance of Solid Valve Handwheels
Makhalidwe azinthu
Zofunika ndiye maziko odziwira -kuletsa dzimbiri kwa mawilo amanja. Pakati pa zipangizo zachitsulo, zitsulo za carbon zimakhala ndi mtengo wotsika koma zimakhala zosavuta kuchita dzimbiri. M'malo achinyezi, gudumu lachitsulo losatetezedwa la kaboni limatha kuwonetsa dzimbiri pakadutsa 1-miyezi iwiri; Chitsulo chosapanga dzimbiri chimakhala ndi kukana bwino kwa dzimbiri chifukwa cha filimu ya passivation yopangidwa ndi zinthu za chromium. Pakati pawo, zitsulo zosapanga dzimbiri 316 zimagwira ntchito bwino kuposa 304 zitsulo zosapanga dzimbiri mu chilengedwe cha chloride ion chifukwa chowonjezera zinthu za molybdenum. Zida zopanda zitsulo monga polytetrafluoroethylene (PTFE) zimakhala ndi mphamvu zokhazikika za mankhwala ndipo zimatha kupirira ma asidi amphamvu ndi alkalis, koma mphamvu zawo zamakina ndizochepa. .
Zinthu zachilengedwe
Zachilengedwe zimakhudza kwambiri-kuletsa dzimbiri. Pankhani ya chinyezi, chinyezi chikamadutsa 60%, kuwononga kwa mawilo achitsulo kudzakwera kwambiri 3-5. Muzinthu zamagetsi, ma oxidizing acid amphamvu (monga concentrated sulfuric acid), alkalis amphamvu (monga sodium hydroxide solution) ndi njira zamchere zimawononga pamwamba pa gudumu lamanja. Kusintha kwa kutentha kudzakhudzanso ntchito ya anti-corrosion. Kutentha kwakukulu kumathandizira kusintha kwamankhwala. Kupsyinjika kwa kutentha komwe kumabwera chifukwa cha kusinthasintha kwa kutentha kungayambitse ma microcracks pamwamba pa handwheel, kupereka njira yodziwira.
Njira yopanga
Njira yochizira pamwamba imakhudza kwambiri -kutha kwa dzimbiri kwa gudumu lamanja. Njira yopangira ma electroplating imapanga chinsalu choteteza pamwamba pa chrome plating, zinc plating, etc.; njira yokutira imagwiritsa ntchito epoxy resin, polyurethane ndi zokutira zina kuti zilekanitse media zowononga; Ukadaulo wopopera mafuta ukhoza kupanga -zotchingira zowoneka bwino kwambiri monga zomangira pazitsulo zachitsulo, zomwe zimapangitsa kuti -zidziyike bwino kwambiri.
Kufananitsa ndi Kuwunika kwa Anti-kuwonongeka kwa Mayendedwe a Handwheels Opangidwa ndi Zida Zosiyanasiyana

Frontier Technologies and Processes to Improve Anti-corrosion Performance
M'zaka zaposachedwa, makampani akhala akuyang'ana njira zatsopano zothana ndi-zidzidzidzi. Ukadaulo wa nano-wopaka utoto umathandiza kuti zisawonongeke popanga nano{3}}filimu yoteteza pamwamba; umisiri-wokonza zokutira umagwiritsa ntchito ukadaulo wa microcapsule kuti utulutse zinthu zokonzetsera zokutira zikawonongeka kuti zikonzeretu malo owonongeka; ukadaulo wa composite material umaphatikiza kulimba kwachitsulo ndi kulimba kwa dzimbiri kosachita-zitsulo kuti apange zinthu zamagudumu apamanja kuti zigwire bwino ntchito.
Kuwonetsedwa kwa Deta Yeniyeni Yoyeserera ndi Case Studies pa Anti-corrosion Performance
Kampani ina yamankhwala inaika zitsulo za carbon, zitsulo zosapanga dzimbiri 304, ndi mawilo 316 a zitsulo zosapanga dzimbiri pa mavavu a pipeline ya sulfuric acid. Pambuyo pa miyezi 6 yogwira ntchito, gudumu la carbon steel handwheel linachita dzimbiri ndipo kuya kwa dzimbiri kunafika 0.3mm; gudumu la 304 lachitsulo chosapanga dzimbiri linawonetsa kuponya pang'ono ndipo kuya kwa dzimbiri kunali 0.05mm; gudumu la 316 lachitsulo chosapanga dzimbiri linalibe zosintha zodziwikiratu. Mlanduwu umasonyeza mwachindunji kusiyana kwa machitidwe a mawilo a manja opangidwa ndi zipangizo zosiyanasiyana m'malo owononga kwambiri.
Mayendedwe Akukula kwa Makampani: Mayendedwe Atsopano a Anti-corrosion Technology in the Future
M'tsogolomu, popanga nzeru zamakampani, kuyang'anira mwanzeru komanso kuchenjeza anthu msanga adzaphatikizidwa ndi ukadaulo wothana ndi-wolimbana ndi dzimbiri kuti ziwonetsere momwe magudumu akunyowa mu nthawi yeniyeni. Panthawi imodzimodziyo, zinthu zoletsa kuwononga chilengedwe ndi -zidzalowa m'malo mwa -umisiri wowononga chilengedwe kuti zikwaniritse zofunikira za chitukuko chokhazikika. Kuphatikiza apo, mfundo za bionic zidzagwiritsidwanso ntchito poletsa-kukonza dzimbiri, kutsanzira zachilengedwe-zosagwira dzimbiri komanso kupanga zida zatsopano zothira dzimbiri.
