Waya dzeNickel-chromium (Nichrome) alloy dzinoshandiswa zvakanyanya muminda yekupisa, yemagetsi, uye yemaindasitiri nekuda kwekudzivirira kwavo kupisa kwakanyanya uye kushanda kwavo kwemagetsi kwakasimba. Pakati padzo,Nicr7030uyeNicr8020ndiwo mamodheru maviri anonyanya kuzivikanwa, asi pane musiyano mukuru mukuumbwa, mashandiro, uye mashandisirwo. Pazasi pane kuenzanisa kwakadzama kuti kukubatsire kuita sarudzo dzekutenga neruzivo:

Kuongorora Kusiyana Kwakadzama

1. Kuumbwa kweMakemikoro & Kushanda Kwazvo

Musiyano mukuru uri muhuwandu hwenickel-chromium: Nicr7030 ine 30% chromium (yakakwirira kupfuura 20%) yeNicr8020, izvo zvinowedzera kugona kwayo kuchinjika uye kuchinjika. Nekureba kwayo pakuputsika kwe ≥25%, Nicr7030 inogona kudhonzwa muwaya dzakapfava (kusvika ku 0.01mm) kana kukotama kuita maumbirwo akaomarara, zvichiita kuti ive yakakodzera zvigadzirwa zvinoda kugadziriswa kwakanyatsojeka (semuenzaniso, waya dzemotoka dzinodziya, masensa emagetsi madiki).

Kusiyana neizvi, huwandu hwakawanda hweNicr8020 hwenickel (80%) hunovandudza kugadzikana kwayo pakupisa kwepamusoro, zvichiita kuti irambe ichishanda pa1300°C—50°C kupfuura Nicr7030. Zvisinei, izvi zvinouya nekuda kwekudzikira kwe ductility (≥15%), zvichiita kuti isakodzere kukotamisa kana kugadzira maitiro. Mamwe mamodheru akaita seNicr6040 ane huwandu hwakaderera hwenickel, zvichikonzera kudzikira kwe resistivity uye kuramba tembiricha, zvichideredza kushandiswa kwawo kune mamiriro ekunze asina kudiwa zvakanyanya.

2. Kudzivirira uye Kushanda Nesimba

Kuramba kuchipisa kunokanganisa zvakananga kushanda zvakanaka kwekupisa uye dhizaini yezvikamu. Nicr8020 ine kuramba kuchipisa kwakanyanya (1.40 Ω·mm²/m2), zvichireva kuti inogadzira kupisa kwakawanda pahurefu hweyuniti pasi pesimba rimwechete, zvichiita kuti ikodzere zvinhu zvinodziya zvine simba guru (semuenzaniso, maovheni anodziya ane kupisa kwakanyanya).

Kudzivirira kwaNicr7030 kuri pakati nepakati (1.18 Ω·mm²/m2) kunoratidza chiyero pakati pekugadzirwa kwekupisa nekushandiswa kwesimba. Kune akawanda mashandisirwo emaindasitiri nevatengi (semuenzaniso, maovheni, ma heating pads), inopa simba rekupisa rakakwana uku ichideredza marara esimba. Pamusoro pezvo, kudzivirira kwayo kugadzikana (±0.5% kutsungirira) kunoita kuti ishande zvakanaka panguva yekushandiswa kwenguva refu, zvichidzivirira kushanduka kwekushisa.

3. Kuramba Kuoxidation & Hupenyu hweBasa

Nicr7030 neNicr8020 dzinogadzira mafirimu ekudzivirira eCr₂O₃ pakupisa kwakanyanya, asi huwandu hwakawanda hwechromium muNicr7030 hunogadzira firimu rakakora uye rinogara kwenguva refu. Izvi zvinoita kuti irambe "yakaora zvakasvibira" (intergranular oxidation) mumhepo ine hunyoro kana kuti inodzikisa hunyoro, zvichiita kuti irambe ichishanda kwemaawa anopfuura 8000 (20% yakareba kupfuura Nicr8020 munzvimbo dzakaoma).

Nicr6040, ine chromium shoma, ine oxide film isina kugadzikana iyo inokurumidza kudonha kana tembiricha iri pamusoro pe1000°C, zvichiita kuti hupenyu hwebasa hupfupike uye mari yekugadzirisa iwedzere.

4. Kuchinjika Kwemutengo & Mashandisirwo

Nicr7030 inopa kushanda zvakanaka pamutengo wayo: huwandu hwayo hwenickel hwakaderera (kana tichienzanisa neNicr8020) hunoderedza mitengo yezvinhu zvakagadzirwa ne15-20%, nepo kushanda kwayo kwakasiyana-siyana kuchifukidza 80% yekushandiswa kwewaya yenichrome. Ndiyo sarudzo inosarudzwa yezvigadzirwa zvakagadzirwa zvakawanda zvakaita semidziyo yemumba uye masisitimu ekudziyisa mota, uko kuenzanisa kushanda kwayo nemutengo kwakakosha.

Nicr8020 ine nickel yakawanda inowedzera mutengo wayo, zvichiita kuti ishandiswe chete pakushandisa tembiricha yepamusoro (semuenzaniso, kuyedzwa kwezvikamu zvemuchadenga). Mamwe mamodheru ane nickel shoma seNicr6040 akachipa asi haana mashandiro anoenderana nezvinodiwa zvemaindasitiri kana zvemagetsi.

Gwaro Rekusarudza

• SarudzaNicr7030kana uchida: Kushanda kwakasiyana-siyana, kugadzirisa kuri nyore (kukotama/kunamira), kushanda zvakanaka kwemari, uye kushandiswa mumidziyo yemumba, kudziyisa mota, kudziyisa mumaindasitiri, kana michina yemagetsi chaiyo.
• SarudzaNicr8020kana uchida: Tembiricha yepamusoro yekushandisa (1300°C+) uye zvinhu zvidiki zvinodziya zvine simba guru (semuenzaniso, maovheni eindasitiri akasarudzika).
• Sarudza mamwe mamodheru (semuenzaniso, Nicr6040) chete kana paine tembiricha yakaderera uye isingade zvakanyanya (semuenzaniso, ma resistors ekutanga).

Nekushanda kwayo kwakaringana, kushanda kwayo zvakanaka, uye kugona kuchinjika kwakasiyana-siyana, Nicr7030 ndiyo sarudzo inodhura zvishoma kune vatengi vazhinji. Kambani yedu inopa magadzirirwo akagadzirirwa vatengi (dhayamita, kureba, kurongedza) uye rutsigiro rwehunyanzvi kuitira kuti Nicr7030 ikwane zvakakwana nezvinodiwa neapplication yako.
