Momwe mungapangire dzimbiri pagalimoto ndi manja anu
Zamkatimu
Kukonza malo ang'onoang'ono (malo a dzimbiri), batri "chala" chimodzi ndi chokwanira. Koma onetsetsani kuti mwatenga saline, momwe thupi limapangidwira pafupifupi 100% zinc.
Galvanizing galimoto ikuchitika kuteteza thupi ku dzimbiri ndi kuchotsa dzimbiri malo. Mutha kugula kapangidwe kapadera kapena kugwiritsa ntchito asidi ndi batri. Tiyeni tiwone momwe mungapangire dzimbiri pagalimoto nokha.
Momwe mungapangire dzimbiri pagalimoto nokha
Kudzilimbitsa thupi lagalimoto, njira ziwiri zimagwiritsidwa ntchito:
- Galvanic. Kulumikizana kumakhazikika pamwamba pa galimoto pogwiritsa ntchito electrochemistry.
- Kuzizira. Chida chokhala ndi zinc chimagwiritsidwa ntchito pa zokutira zowononga dzimbiri.
Njira yoyamba ndi yabwino, chifukwa zinki ndipamene filimu wandiweyani kwambiri mothandizidwa ndi magetsi. Cold galvanizing ndi kosavuta kuchita, koma kenako thupi limakhala losakhazikika ku kuwonongeka kwa makina.
Mu garaja, ndizovuta kwambiri kubwezeretsa thupi la galimoto ndi manja anu. Nthawi zambiri, malo owonongeka amapangidwa ndi malata m'deralo. Kawirikawiri, zipinda, zotchingira galimoto, pansi, magudumu a magudumu kapena zowonongeka zimakonzedwa.
Zinc imagwiritsidwa ntchito pobwezeretsa thupi, chifukwa ndi yotsika mtengo, siiwononga komanso imakhala yolimba kwambiri.

Magawo a ntchito ndi zipangizo
Galvanize kokha mu mpweya wokwanira bwino garaja, kapena bwino panja. Kuti mugwiritse ntchito njira yotsika mtengo kwambiri ya galvanic, mudzafunika:
- batire ngati gwero la zinki;
- chidutswa cha thonje kapena thonje pad;
- tepi yamagetsi ndi chidutswa cha waya ndi "ng'ona";
- orthophosphoric acid;
- degreaser iliyonse yachitsulo;
- soda.
Kukonza malo ang'onoang'ono (malo a dzimbiri), batri "chala" chimodzi ndi chokwanira. Koma onetsetsani kuti mwatenga saline, momwe thupi limapangidwira pafupifupi 100% zinc.
Njira yonse yochotsera dzimbiri pang'ono imatenga theka la ola:
- Chotsani filimuyo ku batri, chotsani ndodo ya graphite ndi zonse zamkati.
- Kumbali yabwino, pezani waya ndikuyiteteza ndi tepi yamagetsi.
- Tsekani mapeto a batri ndi ubweya wa thonje ndikugwedeza tepi kachiwiri.
- Lumikizani "ng'ona" kumbali ina ya waya ku ma terminals a batri yagalimoto.
- Degretsani malo mankhwala.
- Zilowerereni bwino thonje ndi asidi ndikutsamira pa dzimbiri. Mudzawona nthawi yomweyo momwe zimakhalira.
Panthawi yosinthika, banja la galvanic limapangidwa, momwe zinc yogwira imapanga filimu wandiweyani pamwamba. Nyowetsani ubweya wa thonje ndi asidi pafupipafupi momwe mungathere kuti wosanjikizawo ukhale wokhuthala.
Nthawi zambiri pamakhala ndemanga pamabwalo kuti sikoyenera kuyeretsa dzimbiri. Inde, iye mwini adzachoka kwenikweni pambuyo pa mphindi ziwiri za kukhudzana ndi zitsulo dzimbiri. Koma mu nkhani iyi, zokutira zinc adzakhala bodza zoipa.
Acid kwa galvanizing galimoto
Phosphoric acid ndi yoyenera kwambiri pakupangira galvanizing. Imakhala ngati electrolyte, imalimbana ndi dzimbiri, ma oxides ndipo imalepheretsa mapangidwe awo.
Ngati mukukonza dera lalikulu la thupi, ndiye kuti mufulumizitse ndondomekoyi, mukhoza kusungunula pepala la zinki lolemera 100 g mu 100 ml ya asidi.
Zolakwa Zomwe Zingatheke Pamene Mukupanga Dzimbiri
Pansi pazikhalidwe zonse za galvanizing, filimu yopepuka ya silvery imapangidwa pamwamba. Ngati adadetsedwa:
- kapena kawirikawiri zilowerere mpira wa thonje mu asidi;
- kapena kubweretsa mbali yolakwika ya batri pafupi kwambiri ndi batire.
Kulakwitsa kwina ndikuyiwala kutsitsa zitsulo musanayambe ndondomekoyi. Zinc idzapangabe filimu, koma ikhoza kusweka pakatha chaka. Degreasing kumawonjezera moyo wa thupi ndi kuteteza maonekedwe a dzimbiri pamene kusenda penti.
