Choyamba, ndikofunikira kufotokoza bwino ubale wawo:Nichrome(chidule cha nickel-chromium alloy) ndi gulu lalikulu la ma alloys okhala ndi nickel-chromium, pomweNdi80ndi mtundu winawake wa nichrome wokhala ndi kapangidwe kokhazikika (80% nickel, 20% chromium). "Kusiyana" kuli mu "gulu lonse poyerekeza ndi mtundu wina"—Ni80 ndi ya banja la nichrome koma ili ndi mawonekedwe apadera chifukwa cha kukhazikika kwake, zomwe zimapangitsa kuti ikhale yoyenera pazochitika zapadera kutentha kwambiri. Pansipa pali kufananiza kwatsatanetsatane:
| Mbali | Nichrome (Gulu Lonse) | Ni80 (Specific Nichrome Variant) |
| Tanthauzo | Banja la alloys lomwe limapangidwa makamaka ndi nickel (50-80%) ndi chromium (10-30%), ndi zowonjezera zina (monga chitsulo) | Mtundu wapamwamba wa nichrome wokhala ndi kapangidwe kokhwima: 80% nickel + 20% chromium (palibe zowonjezera zina) |
| Kusinthasintha kwa kapangidwe | Ma ratio osinthika a nickel-chromium (monga, Ni60Cr15, Ni70Cr30) kuti akwaniritse zosowa zosiyanasiyana | Chiŵerengero chokhazikika cha nickel-chromium cha 80:20 (palibe kusinthasintha kwa zigawo zazikulu) |
| Magwiridwe Ofunika | Kukana kutentha kwapakati (800–1000°C), kukana kwa okosijeni, ndi kukana kwamagetsi kosinthika | Kukana kutentha kwambiri (mpaka 1200°C), kukana kwabwino kwambiri kwa okosijeni (kuchepa kwa kukula pa 1000°C+), ndi kukana kwamphamvu kwamagetsi (1.1–1.2 Ω/mm²) |
| Mapulogalamu Odziwika | Kutentha kwapakati pa kutentha kochepa (monga machubu otenthetsera zipangizo zapakhomo, zotenthetsera zazing'ono, zotenthetsera zamafakitale zamagetsi ochepa) | Zochitika zokhudzana ndi kutentha kwambiri, zomwe zimafunidwa kwambiri (monga, ma coil a furnace a mafakitale, ma hot end a 3D printer, zinthu zochotsera icing mumlengalenga) |
| Zoletsa | Kutentha kotsika kwambiri; magwiridwe antchito amasiyana malinga ndi chiŵerengero china (mitundu ina imasungunuka mwachangu kutentha kwambiri) | Mtengo wokwera wa zinthu zopangira; zoyenerera kwambiri pazochitika zotentha pang'ono (zosawononga ndalama zambiri) |
1. Kapangidwe: Kokhazikika vs. Kosinthasintha
Nichrome monga gulu imalola ma ratios osinthika a nickel-chromium kuti agwirizane ndi mtengo ndi magwiridwe antchito. Mwachitsanzo, Ni60Cr15 (60% Ni, 15% Cr) imawonjezera chitsulo kuti ichepetse mtengo koma imachepetsa kukana kutentha. Mosiyana ndi zimenezi, Ni80 ili ndi chiŵerengero chosakambidwa cha nickel-chromium cha 80:20—kuchuluka kwa nickel kumeneku ndi chifukwa chake kumaposa mitundu ina ya nichrome pakukana okosijeni ndi kulekerera kutentha. Ni80 yathu imatsatira kwambiri muyezo wa 80:20, ndi kulondola kwa kapangidwe mkati mwa ± 0.5% (yoyesedwa kudzera mu atomic absorption spectroscopy).
2. Magwiridwe antchito: Zapadera vs. Cholinga Chachikulu
Pazofunikira kutentha kwambiri (1000–1200°C), Ni80 ndi yosayerekezeka. Imasunga kukhazikika kwa kapangidwe kake m'mafakitale kapena ma hot end a 3D printer, pomwe nichrome ina (monga Ni70Cr30) ingayambe kusungunuka kapena kusokonekera kuposa 1000°C. Komabe, pa ntchito zotentha zapakati (monga chotenthetsera tsitsi cha 600°C), kugwiritsa ntchito Ni80 sikofunikira—mitundu yotsika mtengo ya nichrome imagwira ntchito bwino. Mzere wathu wazinthu umakhudza Ni80 (pazinthu zomwe zimafunidwa kwambiri) ndi nichrome ina (pazofunikira zotsika mtengo komanso kutentha kochepa).
3. Kugwiritsa Ntchito: Yolunjika vs. Yotakata
Gulu lalikulu la Nichrome limakwaniritsa zosowa zosiyanasiyana za kutentha kochepa mpaka pakati: Ni60Cr15 ya zotenthetsera zazing'ono zapakhomo, Ni70Cr30 ya ulusi wa toaster wamalonda. Mosiyana ndi zimenezi, Ni80 imayang'ana kwambiri ntchito zotenthetsera kwambiri: imalimbitsa ng'anjo zamafakitale (komwe kutentha kuli kofanana ndikofunikira) ndi machitidwe ochotsa icing mumlengalenga (komwe kukana kuzizira kwambiri/kutentha ndikofunikira). Ni80 yathu yavomerezedwa ndi ASTM B162 (miyezo yamlengalenga) ndi ISO 9001, kuonetsetsa kuti idalirika m'magawo ovuta awa.
Kodi Mungasankhe Bwanji Pakati pawo?
- Sankhani nichrome wamba (monga, Ni60Cr15, Ni70Cr30) ngati: Mukufuna kutentha kwapakati (<1000°C) ndikusankha kugwiritsa ntchito bwino ndalama (monga zipangizo zapakhomo, zotenthetsera zazing'ono).
- Sankhani Ni80 ngati: Mukufuna kukhazikika kutentha kwambiri (>1000°C), nthawi yayitali yogwira ntchito (maola 10,000+), kapena kugwira ntchito m'mafakitale ofunikira (mlengalenga, kupanga mafakitale).
Gulu lathu limaperekaupangiri waulere—tikuthandizani kufananiza mtundu woyenera wa nichrome (kuphatikiza Ni80) ndi pulogalamu yanu, ndikuwonetsetsa kuti ikugwira ntchito bwino komanso kuti mtengo wake ndi wokwera bwino.
