Abubuwan Juriya na Lalacewa Na Nickel{0}} tushen Alloy Materials

Juriya na lalata na nickel{0} tushen gami ya bambanta dangane da nau'in su da matsakaicin da ake amfani da su a ciki.

 

1. Tsabtace Nickel (Nickel 201/Nickel 200)
Filin aikace-aikace:
Juriya ga kafofin watsa labarai na alkaline (kamar sodium hydroxide);
Mai tsayayya ga tsaka tsaki ko raunin acidic gishiri mafita, ruwa mai dadi, ruwan teku;
Ba ya jure wa acid mai ƙarfi mai ƙarfi (kamar sulfuric acid mai ƙarfi, nitric acid).
Matsayin lalata: A mafi yawan wurare masu laushi, yana da "mafi kyau" (ƙimar lalata <0.1 millimeters a kowace shekara).

 

2. Nickel -Garin Copper (Monel 400/Monel K-500)
Filin aikace-aikace:
Juriya ga ruwan teku, hydrofluoric acid, phosphoric acid, Organic acid;
Mai jurewa ga lalata damuwa na chloride (mafi kyaun bakin karfe);
Ba ya jure wa ƙaƙƙarfan muhallin oxidizing da matsanancin zafi na hydrogen sulfide.
Matsayin lalata: "Madalla" (ƙananan ƙarancin lalata) a cikin yanayin ruwa da sinadarai.

 

3. Nickel{1}}Chromium Alloy (Inconel 600/Inconel 625)
Filin aikace-aikace:
Mai jurewa ga matsanancin iskar oxygen, acid nitric, acid Organic, da lalata damuwa na chloride;
Dace don musanya oxidizing - rage mahalli.
Matsayin lalata: "Madalla" a cikin yanayin zafi mai ƙarfi da matsananciyar sinadarai (ƙimar lalata <0.05 mm/ shekara).

 

4. Nickel{1} Molybdenum Alloy (Hastelloy B/Hastelloy B-2)
Filin aikace-aikace:
Mai jurewa ga acid hydrochloric, sulfuric acid, phosphoric acid, da sauransu (marasa -acid oxidizing);
Ba da juriya ga kafofin watsa labaru masu ɗauke da oxidants (kamar Fe³⁺, Cu²⁺).
Lalata daraja: "Madalla" a cikin rage acid (kusan babu lalata)

 

5. Nickel -Chromium{2}}Molybdenum Alloy (Hastelloy C-276/C-22)
Filin aikace-aikace:
Juriya ga oxidizing acid (nitric acid, gauraye acid), chloride, da danshi chlorine gas;
Matsananciyar juriya ga ramuka da lalata lalata.
Lalacewar daraja: "Mafi" a cikin gauraye acid da matsananciyar yanayin masana'antu (ana iya yin watsi da ƙimar lalata)

Ana buƙatar ƙididdige ainihin amfanin da ake amfani da shi dangane da yanayi, zafin jiki, tattarawar samfur da kuma oxidation - rage aikin;
A cikin yanayi tare da sulfur ko babban damuwa, ana buƙatar ƙira na musamman (kamar ƙara tungsten, jan karfe, da dai sauransu);
Idan kuna buƙatar ba da shawarar abubuwan haɗin nickel{0} don takamaiman mahalli, da fatan za a samar da cikakkun yanayi (kamar matsakaicin pH, oxidation{1}} rage aikin, gurɓataccen abu, da sauransu).
