China Nichrome Ni80Cr20 waya yakati sandara ine simba rakanaka rekudzivirira oxidation Kugadzira uye Fekitori

Waya yakatsetseka yeNichrome Ni80Cr20 ine hunhu hwakanaka hwekudzivirira oxidation

Tsananguro pfupi:

Ruzivo rweChigadzirwa

Mibvunzo Inowanzo bvunzwa

Matagi eChigadzirwa

Chinhu chinonzi NiCr8020 chine nhamba 2.4869 chinoshandiswa muchimiro chezvidimbu, machira, machubhu uye waya dzezvikamu zvekuvaka vira uye zvinofambisa kupisa.

Imhando ye nickel-chromium heating conductor alloy inoshandiswa pakushanda tembiricha inosvika 1150 °C uye inowanzo kuve nezvinhu zvinowedzera zve rare earths kuti irambe yakasimba mukuoxidation, kunyanya kana paine kuchinja-chinja kana kuchinja tembiricha zvakanyanya.

Kuramba ngura yemumhepo pa20°C kwakakwira kusvika patembiricha yepamusoro yekushanda, kuramba pamhepo nemamwe magasi ane okisijeni pamwe nemagasi ane nitrogen ane okisijeni shoma kwakakwirawo, asi kwakaderera pakuoxidiza pamwe nekuderedza magasi ane sarufa.

Kuramba kupiswa necarbon kwakakwira. Kushandiswa kwemaovheni emagetsi emaindasitiri, maovheni eenameling, midziyo yemumba, maheater ekuchengetedza zvinhu anobatidza magetsi husiku.

Huru Huru uye Kushandiswa

1. Nickel-chromium, nickel-chromium alloy ine simba rakasimba uye rakagadzikana, inodzivirira ngura, inodzivirira oxidation pamusoro, ine simba rakanaka kana tembiricha yakakwira uye simba rekudengenyeka kwenyika, ine ductility yakanaka, inoshanda zvakanaka uye inogona kusvetwa.
2. Zvigadzirwa zvedu zvinoshanda zvakanyanya muindasitiri yemakemikari, michina yesimbi, indasitiri yegirazi, indasitiri yeceramic, nzvimbo yemidziyo yemumba nezvimwewo.
