Posachedwapa, fakitale yathu ikupanga gulu la zitsulo zosapanga dzimbirizipata zotseguka, yomwe ndi mtundu watsopano wa chipata cholumikizidwa pakhoma chopangidwa ndi fakitale yathu, pogwiritsa ntchito ukadaulo wopindika zisanu, kusintha pang'ono komanso kutseka mwamphamvu. Pambuyo papenstock ya pakhomaPakuwotcherera ma valve, padzakhala kusintha kwakuda, komwe kumakhudza mawonekedwe, makamaka chifukwa cha kutentha kwambiri panthawi yowotcherera, kotero kuti chitsulo chomwe chili pamwamba pa valve chimasungunuka, ndikupanga filimu yakuda ya oxide.

Njira yotsatirayi ikufotokoza njira yophikira pothana ndi blackening:

Fakitale ya Jinbin imagwiritsa ntchito njira yotsukira ndi electrolytic, pogwiritsa ntchito electrolytic action ndi chemical corrosion ya asidi kuchotsa filimu yakuda ya oxide pamwamba pa valavu. Mu njira ya electrolytic, valavu imagwira ntchito ngati anode, ndipo filimu ya oxide pamwamba pa chitsulo imasinthidwa kukhala ion pansi pa mphamvu ya magetsi pambuyo poti yapatsidwa mphamvu, ndikupanga ma ayoni achitsulo osungunuka mu yankho la asidi, motero kufulumizitsa kuchotsa filimu ya oxide. Nthawi yomweyo, ma ayoni a hydrogen mu asidi amachita ndi ma oxide achitsulo kuti asungunuke ndikukwaniritsa cholinga choyeretsa pamwamba pa valavu.

Kuyenda kwa njira yophikira:

1. Kukonza pamwamba: Musanapange pickling, ndikofunikira kuchita kaye kukonza pamwamba pa valavu, monga kugwiritsa ntchito njira zamakina kuchotsa mafuta, dzimbiri, slag yowotcherera ndi zinyalala zina pamwamba kuti asidi athe kukhudza filimu ya oxide ndikuwonjezera mphamvu ya pickling.

Ikani ndi kupachika valavu molondola pamalo a anode a chipangizo chopangira electrolytic pickling kuti muwonetsetse kuti kukhudzana pakati pa valavu ndi electrode kuli bwino ndipo mphamvu yamagetsi ikhoza kugawidwa mofanana pamwamba pa valavu.

2. Konzani njira yothira mafuta: Sankhani njira yoyenera ya asidi ndi kuchuluka kwake malinga ndi zinthu ndi kuchuluka kwa okosijeni kwa valavu. Ma asidi wamba ndi sulfuric acid, nitric acid, hydrochloric acid, ndi zina zotero, kapena kusakaniza kwawo. Mwachitsanzo, pa mavalavu achitsulo chosapanga dzimbiri, kusakaniza kwa nitric acid ndi hydrofluoric acid nthawi zambiri kumagwiritsidwa ntchito. Pokonza asidi, ndikofunikira kutsatira mosamala njira zogwirira ntchito, kulabadira kuchuluka kwa asidi, kutentha ndi kuchuluka kwa zowonjezera ndi zina.

3. Kuthira madzi mu electrolytic: Thirani asidi wokonzedwa mu selo ya electrolytic, yatsani magetsi a electrolytic, ndikuwongolera kuchuluka kwa magetsi, nthawi yamagetsi ndi kutentha kwa asidi ndi zina. Kawirikawiri, kuchuluka kwa magetsi mu electrolytic kumakhala kwakukulu komanso nthawi yayitali yamagetsi, kumabweretsa zotsatira zabwino zochotsera filimu ya oxide, koma nthawi yomweyo, chisamaliro chiyenera kutengedwa kuti tipewe kuthira madzi mu electrolytic zomwe zimapangitsa kuti chitsulo cha pamwamba pa valve chizizire kwambiri. Kutentha kwa asidi nthawi zambiri kumayendetsedwa mkati mwa mtunda winawake, kutentha kwambiri kumatha kufulumizitsa kusinthasintha kwa kutentha ndi kuwonongeka kwa asidi, zomwe zimakhudza momwe kuthira madzi kumakhalira, ndipo kutentha kochepa kwambiri kungayambitse kuti liwiro la reaction likhale lochedwa kwambiri.

4. Kutsuka ndi madzi: Mukamaliza kutsuka ndi electrolytic, chotsani valavu mu asidi ndikuyiyika mwachangu m'madzi oyera oyenda kuti mutsuke kuti muchotse asidi wotsala ndi zinthu zomwe zimachitika pamwamba pa valavu. Nthawi yotsuka ndi liwiro la madzi ziyenera kukhala zokwanira kuonetsetsa kuti pH ya pamwamba pa valavu ifike patali komanso kupewa asidi wotsala kuti asapangitse dzimbiri ku valavu.

5. Pambuyo pa chithandizo: Vavu ikatha kutsukidwa imatha kukonzedwanso ngati pakufunika, monga chithandizo cha passivation, chithandizo cha anti-dzimbiri, ndi zina zotero, kuti iwonjezere kukana dzimbiri ndi moyo wa ntchito ya valavuyo. 

Jinbin Valve monga wopanga ma penstock, wopanga mitundu yonse ya ma valve achitsulo, chipata cha penstock chachitsulo chosapanga dzimbiri, ma valve a chipata chachikulu cha mainchesi, ma valve a gulugufe, ndi zina zotero, ngati muli ndi zosowa zina, chonde siyani uthenga pansipa kapena tumizani imelo kuti mutitumizire, mudzalandira yankho mkati mwa maola 24, ndikuyembekezera kugwira nanu ntchito!
