Kutanga, chinhu chikuru ndechekujekesa hukama hwavo:Nichrome(muchidimbu che nickel-chromium alloy) iboka rakakura re alloys dzakavakirwa pa nickel-chromium, nepoNi80imhando chaiyo ye nichrome ine chimiro chakasimba (80% nickel, 20% chromium). "Musiyano" uri mu "general category vs. specific variant"—Ni80 ndeyemhuri ye nichrome asi ine hunhu hwakasiyana nekuda kwechimiro chayo chakasimba, zvichiita kuti ive yakakodzera kune zviitiko zvekupisa zvakanyanya. Pasi apa pane kuenzanisa kwakadzama:
| Chikamu | Nichrome (Chikamu Chakazara) | Ni80 (Chaiyo Nichrome Variant) |
| Tsanangudzo | Mhuri ye alloys inoumbwa zvakanyanya ne nickel (50–80%) uye chromium (10–30%), ine zvimwe zvinowedzerwa (semuenzaniso, simbi) | Mhando yepamusoro ye nichrome ine maumbirwo akasimba: 80% nickel + 20% chromium (hapana zvimwe zvinowedzera) |
| Kugadzikana kweKuumbwa | Zviyero zve nickel-chromium zvinoshanduka (semuenzaniso, Ni60Cr15, Ni70Cr30) kuti zvienderane nezvinodiwa zvakasiyana | Chiyero che 80:20 nickel-chromium chakagadziriswa (hapana kuchinjika muzvikamu zvepakati) |
| Kushanda Kwakakosha | Kudzivirira kupisa kwakanyanya (800–1000°C), kudzivirira oxidation, uye kudzivirira magetsi kunogadziriswa | Kudzivirira kupisa kwakanyanya (kusvika 1200°C), kudzivirira kupisa kwakanyanya (kudzikama pa1000°C+), uye kudzivirira kwemagetsi kwakasimba (1.1–1.2 Ω/mm²) |
| Maitiro Akajairika | Mamiriro ekupisa epakati nepakati (semuenzaniso, machubhu ekupisa emidziyo yemumba, mahita madiki, mahita emumaindasitiri ane simba shoma) | Mamiriro ezvinhu anonyanya kupisa, anodiwa zvakanyanya (semuenzaniso, macoil efurnace emaindasitiri, 3D printer hot ends, zvinhu zvinobvisa icing mumhepo) |
| Miganhu | Tembiricha yepamusoro yakaderera; mashandiro anosiyana zvichienderana nehuwandu hwakatarwa (mamwe marudzi anokurumidza kuoxida kana tembiricha yakakwira) | Mutengo wezvinhu zvakabikwa wakakwira; zvinodhura zvakanyanya kana zvikashandiswa pakupisa kwakaderera (hazvishandi zvakanaka) |
1. Kuumbwa: Kwakagadziriswa vs. Kuchinjika
Nichrome sechikamu inobvumira kuchinjika kwe nickel-chromium ratios kuti ienzanise mutengo nekushanda. Semuenzaniso, Ni60Cr15 (60% Ni, 15% Cr) inowedzera iron kuderedza mutengo asi inoderedza kupisa. Kusiyana neizvi, Ni80 ine 80:20 nickel-chromium ratio isingakurukurwe—iyi nickel yakawanda ndiyo chikonzero nei ichiita zvakanaka kupfuura mamwe ma nichrome akasiyana mukudzivirira oxidation uye tembiricha. Ni80 yedu inotevedzera zvakanyanya mwero we80:20, nekunyatsorongeka kwekugadzirwa mukati me ±0.5% (yakaedzwa kuburikidza neatomic absorption spectroscopy).
2. Kushanda: Zvakanyanya kukosha vs. Chinangwa Chakazara
Kune zvinodiwa pakupisa kwakanyanya (1000–1200°C), Ni80 haina kuenzana nayo. Inochengetedza kugadzikana kwechimiro mumakiln emaindasitiri kana 3D printer hot ends, nepo mamwe ma nichrome (semuenzaniso, Ni70Cr30) anogona kutanga kuoxidiza kana kuchinja pamusoro pe1000°C. Zvisinei, kune mabasa ekupisa kwepakati nepakati (semuenzaniso, hita ye600°C hairdryer), kushandisa Ni80 hazvidikanwi—mhando dze nichrome dzakachipa dzinoshanda zvakanaka. Rudzi rwedu rwechigadzirwa runofukidza Ni80 (kune zviitiko zvinoda kudiwa zvakanyanya) uye mamwe ma nichrome (kune zvinodiwa zvinodhura zvakanyanya uye zvinodziya zvishoma).
3. Mashandisirwo: Yakanangwa vs. Yakafara
Chikamu chakakura cheNichrome chinopa zvinodiwa zvakasiyana-siyana zvekupisa zviri pasi kusvika pakati: Ni60Cr15 yemidziyo midiki yekudziyisa mumba, Ni70Cr30 yemidziyo yekupisira toaster yekutengeserana. Kusiyana neizvi, Ni80 inotarisa kushandiswa kwepamusoro-soro, uye tembiricha yepamusoro: inosimbisa maovheni ekupisa eindasitiri (uko kufanana kwetembiricha kwakakosha) uye masisitimu ekubvisa icing mundege (uko kuramba kutonhora zvakanyanya/kupisa kwakakosha). Ni80 yedu ine chitupa cheASTM B162 (mipimo yendege) uye ISO 9001, ichivimbisa kuvimbika muminda iyi inoda simba.
Ungasarudza Sei Pakati Pavo?
- Sarudza nichrome yakajairika (semuenzaniso, Ni60Cr15, Ni70Cr30) kana: Muchida kupisa tembiricha iri pakati nepakati (<1000°C) uye tangai nekushandisa mari zvakanaka (semuenzaniso, midziyo yemumba, mahita madiki).
- Sarudza Ni80 kana: Uchida kugadzikana pakupisa kwakanyanya (>1000°C), hupenyu hurefu hwekushanda (maawa anopfuura 10,000), kana kushanda mumaindasitiri akakosha (mudenga, kugadzira maindasitiri).
Chikwata chedu chinopakubvunzana kwemahara—tichakubatsira kuenzanisa nichrome yaunoda (kusanganisira Ni80) neyako application, tichiona kushanda zvakanaka uye kushanda zvakanaka kwemari.
