Alloy20 Tilmaamaha
Alloy N08020 waa nikkel-iron-chromium austenitic alloy leh iska caabin heer sare ah si ay u weeraraan aashitada, dalool iyo daxalka dillaacsan iyo sidoo kale chloride-ka kooban acids iyo kiimikooyinka, daxalka guud iyo daxalka intergranular.Alloysku wuxuu isku daraa caabbinta daxalka oo aad u fiican, sahlanaanta wax-soo-saarka iyo qalabka farsamada ee la xoojiyay.
Alloy N08020 waxaa sidoo kale loo yaqaannaa Carpenter 20, Incoloy iyo 20Cb-3.
N08020 waa niobium xasiloon kaarboon hoose oo austenitic nikkel-iron-chromium alloy ka kooban naxaas iyo molybdenum.
• Iska caabin heer sare ah oo ka dhan ah sulfuric acid iyo phosphoric acid Corrosion
• Iska caabbinta wanaagsan ee daxalka intergranular
• Aad ugu adkaysanaysa dildilaaca daxalka ee ay sababto ion chloride
• Iska caabbinta wanaagsan ee daxalka godadka iyo dillaaca
• Sifooyin farsamo oo wanaagsan heerkulka qolka iyo heerkulka sare ilaa 500°C (930°F)
Cuf-jiid gaar ah: 8.08;
N08020 iska caabin daxalka:
N08020 waxay soo bandhigaysaa iska caabbinta daxalka wanaagsan ee xalalka aqueous ee sulfuric acid, phosphoric acid iyo acids organic iyo milixdooda.Waxa kale oo ay leedahay iska caabin wanaagsan oo nitric acid ah.Iyada oo la hagaajinayo isku-dhafka kiimikada, waxay soo bandhigaysaa iska caabin heer sare ah oo ku wajahan noocyada kala duwan ee daxalka sida daxalka intergranular iyo daxalka walbahaarka.Molybdenum sidoo kale waxaa lagu soo daray si loo hubiyo iska caabbinta godadka iyo daxalka dillaaca.Si loo kordhiyo iska caabbinta daxalka, walaxda waa in lagu hayaa macdan ahaan sax ah oo nadiif ah.
N08020 waxa ku jira naxaas iyo molybdenum, kuwaas oo wanaajinaya iska caabbinta walaxda bay'ada adag iyo iska caabinta daxalka iyo dildilaaca.Niobium waxaa loo isticmaalaa in lagu dejiyo walxaha oo lagu yareeyo roobabka carbide inta lagu jiro alxanka.Tani waxay u ogolaanaysaa alaabta alxanka in loo isticmaalo meelaha daxalaystay iyada oo aan daawaynta kulaylka ka dib alxanka iyaga.Nikkelku waxa uu kordhiyaa iska caabbinta dillaaca daxalka chloride.
Meelaha Codsiga Alaabta ee Alloy20
Alloy 20 waa bir-ku-saleysan austenitic alloy loo sameeyay si looga hortago daxalka sulfuric acid.Waxay leedahay iska caabin aad u wanaagsan oo u leh daxalka sulfuric acid;waxay leedahay iska caabin adag oo aysiidh fosfooraska ah, nitric acid iyo chloride deegaanka, daxalka culayska kolorida, daxalka godka iyo dildilaaca.Sidaa darteed, daawaha 20 wuxuu leeyahay magaca daaha-daxalka.
Waxay leedahay codsiyo badan oo kala duwan: sida: kiimiko, cunto, daawo, wax soo saar koronto iyo warshadaha balaastikada ayaa isticmaali doona.Iska caabbinta daxalka iyo daxalka chloride, dhibaatooyinka dildilaaca daxalka, iwm., daawaha 20 ayaa inta badan la isticmaalaa.
