N'chifukwa chiyani zitsulo zosapanga dzimbiri zimachita dzimbiri?

1. Kodi chitsulo chosapanga dzimbiri ndi chiyani?

Chitsulo chosapanga dzimbiri ndi mtundu wachitsulo.Chitsulo chimatanthawuza chitsulo chomwe chili ndi mpweya wosakwana 2% (c), ndi chitsulo choposa 2%.Zinthu za aloyi monga chromium (CR), faifi tambala (Ni), manganese (MN), silicon (SI), titaniyamu (TI) ndi molybdenum (MO) zimawonjezedwa ku chitsulo pakusungunula kuti chitsulo chigwire bwino ntchito. kupanga zitsulo kukhala ndi dzimbiri kukana (ie palibe dzimbiri), chimene nthawi zambiri timachitcha zitsulo zosapanga dzimbiri.Mwachitsanzo, zinthu zathu zosapanga dzimbiri:banjo, chigawo chapakati cha nyumba yozungulira,zikhomo za nyumba,utsi wochuluka, ndi zina.

2. Chifukwa chiyani chitsulo chosapanga dzimbiri chimachita dzimbiri?

Chitsulo chosapanga dzimbiri chimatha kukana makutidwe ndi okosijeni mumlengalenga - kukana dzimbiri, komanso kutha kukana dzimbiri m'malo omwe muli asidi, alkali ndi mchere, ndiko kuti, kukana dzimbiri.Komabe, kukana kwa dzimbiri kwa chitsulo kumasiyana malinga ndi kapangidwe kake ka mankhwala, gawo logwirizana, mkhalidwe wautumiki ndi mtundu wapakati wa chilengedwe.

Chitsulo chosapanga dzimbiri ndi filimu yopyapyala kwambiri, yolimba komanso yabwino yokhazikika ya chromium rich oxide (filimu yoteteza) yomwe imapangidwa pamwamba pake kuteteza maatomu a okosijeni kuti asapitirire kulowa ndikutulutsa okosijeni, ndikupeza kukana dzimbiri.Kanemayo akawonongeka mosalekeza pazifukwa zina, maatomu a okosijeni mumlengalenga kapena zamadzimadzi adzalowa mosalekeza kapena maatomu achitsulo muchitsulocho amadzilekanitsa mosalekeza, kupanga okusayidi yachitsulo yotayirira, ndipo chitsulo pamwamba pazitsulo chidzawonongeka mosalekeza.Pali mitundu yambiri ya kuwonongeka kwa chigoba cha nkhope iyi, ndipo zotsatirazi ndizofala m'moyo watsiku ndi tsiku:

1. Fumbi lomwe lili ndi zinthu zina zachitsulo kapena zomata za tinthu tating'ono ting'onoting'ono zimasungidwa pamwamba pazitsulo zosapanga dzimbiri.Mu mpweya wonyowa, condensate pakati pa zomata ndi zitsulo zosapanga dzimbiri zimawagwirizanitsa mu selo yaying'ono, zomwe zimayambitsa electrochemical reaction ndikuwononga filimu yoteteza, yomwe imatchedwa electrochemical corrosion.

2. Madzi a organic (monga mavwende ndi ndiwo zamasamba, supu yamasamba ndi phlegm) amamatira pamwamba pa chitsulo chosapanga dzimbiri.Pamaso pa madzi ndi mpweya, amapanga ma organic acid, omwe amawononga chitsulo kwa nthawi yayitali.

3. Pamwamba pazitsulo zosapanga dzimbiri zimatsatiridwa ndi asidi, alkali ndi zinthu zamchere (monga madzi a alkali ndi kuyezetsa kwa madzi a laimu kuti azikongoletsa khoma) kuti apangitse dzimbiri.4. Mu mpweya woipitsidwa (mlengalenga womwe uli ndi sulfide yambiri, oxide ndi hydrogen oxide), mukakumana ndi madzi opindika, sulfuric acid, nitric acid ndi acetic acid zamadzimadzi zimapangika, zomwe zimayambitsa dzimbiri.

3, Kodi kuthana ndi dzimbiri mawanga pa zitsulo zosapanga dzimbiri?

a) Chemical njira:

Gwiritsani ntchito phala la pickling kapena kupoperani kuti zigawo zomwe zachita dzimbiri zidutsenso ndikupanga filimu ya chromium oxide kuti zisachite dzimbiri.Pambuyo pa pickling, ndikofunika kwambiri kusamba ndi madzi oyera bwino kuti muchotse zonyansa zonse ndi zotsalira za asidi.Pambuyo pa chithandizo chonse, gwiritsani ntchito zida zopukutira kuti mupukutirenso ndikusindikiza ndi sera yopukutira.Kwa iwo omwe ali ndi dzimbiri pang'ono kwanuko, chisakanizo cha 1: 1 cha petulo ndi mafuta a injini chingagwiritsidwe ntchito kupukuta madontho a dzimbiri ndi chiguduli choyera.

b) Njira yamakina:

Kuyeretsa kuphulika, kuwomberedwa ndi galasi kapena ceramic particles, kuwononga, kupukuta ndi kupukuta.N'zotheka kupukuta kuipitsidwa komwe kumachitika chifukwa cha zinthu zomwe zachotsedwa kale, zipangizo zopukuta kapena zowonongeka ndi njira zamakina.Mitundu yonse ya kuipitsidwa, makamaka yachilendo chitsulo particles, akhoza kukhala gwero la dzimbiri, makamaka m'malo chinyezi.Choncho, ndi makina kutsukidwa pamwamba ayenera mwalamulo kutsukidwa pansi youma zinthu.Njira yamakina imatha kuyeretsa pamwamba, ndipo singasinthe kukana kwa dzimbiri kwa zinthuzo.Choncho, tikulimbikitsidwa kukonzanso ndi zipangizo zopukuta pambuyo poyeretsa makina ndikusindikiza ndi sera yopukutira.
