Nichrome karkace: halaye, aikace-aikace

Nichrome aka ƙirƙira a 1905 da Albert Marsh, wadda ta ha nickel (80%) kuma chromium (20%). Yau akwai game da goma gyare-gyare na gami da daban-daban maki. Kamar yadda ƙarin dopants kara aluminum, manganese, da baƙin ƙarfe, silicon, titanium, molybdenum, kuma t. D. Saboda da kyau kwarai halaye wannan karfe an yadu amfani da samar da wutar lantarki, aikin injiniya.

Basic ingancin Nichrome

Nichrome ne daban-daban:

• high zafi juriya. ta inji Properties ba su canja a high yanayin zafi.
• plasticity, wanda damar samar da wani gami Nichrome karkace waya, kintinkiri, filament.
• kwanciyar hankali na aiki. Products, Ya sanya daga Nichrome da welded, niƙe.
• high jure lalata a daban-daban yanayin.
• high juriya nichrome.

Sa alama Nichrome waya

Nichrome waya - cikakken abu domin da dama lantarki dumama abubuwa, wanda ake amfani da su a kusan dukkan masana'antu. Kusan kowace iyali hita yana da abubuwa da aka yi da nichrome.

Code harafi waya:

• "N" - an kullum amfani da dumama abubuwa.
• "C" - da ake amfani a juriya abubuwa.
• "GOMA" - ne aka yi nufi ga tubular lantarki heaters.

A cewar kasa nagartacce, akwai dama manyan brands:

• Biyu waya Cr20Ni80. A abun da ke ciki na gami hada da: nickel - 74% chromium - 23% da kuma 1% na baƙin ƙarfe, da silicon da manganese.
• Triple H15N60. A gami kunshi 60% nickel da kuma 15% chromium. The uku bangaren - baƙin ƙarfe (25%). baƙin ƙarfe gami jikewa iya rage kudin da nichrome, farashin wanda quite high, yayin da rike da zafi juriya. Bugu da kari, shi qara ta Sannan ina.
• A mafi arha zabin Nichrome - Kh25N20. Wannan ƙarfe-arziki gami a cikin abin da inji Properties aka kiyaye su, amma aiki da zazzabi an iyakance shi zuwa 900 ° C.

A amfani da nichrome

Saboda da inganci da halaye mabambanta na nichrome kayayyakin za a iya amfani da inda dole AMINCI, karko, da juriya ga chemically m yanayi da kuma sosai high yanayin zafi.

Nichrome karkace da waya ne wani ɓangare daga kusan iri daban-daban na dumama na'urorin. Nichrome ne ba a cikin injin ƙyafe burodi, Bakeries, heaters, dafuwa. A gami kuma samu aikace-aikace a resistors da kuma aiki a karkashin matsananci zafi. Akwai Nichrome da kuma wani lantarki fitila da soldering baƙin ƙarfe. Nichrome karkace mallaka babba juriya da kuma zafi juriya, wanda damar su yi amfani da a high zazzabi Tanderu bushewa da kuma harbe-harben.

Ana amfani da da kuma ya da Nichrome. Ya narke saukar, da kuma kayan da ke baya a cikin kasuwanci. nickel-chromium gami amfani da sinadaran dakunan gwaje-gwaje. Wannan abun da ke ciki ba amsa tare da mafi acid da kuma alkalis. Maras kyau dumama Nichrome karkace da ake amfani a lantarki da taba-sigari.

Idan aka kwatanta da baya amfani da wannan manufa da baƙin ƙarfe, Nichrome kayayyakin ne mafi aminci, ba kururuta ha ~ akar, ba tsatsa, ba shi da da spliced rabo.

Narkewa batu nichrome 1400 ° C, don haka a lokacin da dafa ba ji kamshi da tururi.

Injiniyoyi har yanzu gudanar da bincike kan musamman Properties na wannan abu, kullum fadada ikon yinsa, na da aikace-aikace.

A gida, da Nichrome waya da ake amfani da yi na gida da aka yi da kayan aiki, jigsaws da kuma masu saro, kamar da, misali, wata na'ura da yankan kumfa ko itace, a soldering baƙin ƙarfe, a na'urar for kona itace, waldi inji, m heaters, da sauransu. D.

Mafi mashahuri kuma dauke da waya Cr20Ni80 H15N60.

A ina zan iya saya Nichrome waya

Aiwatar da wannan samfurin da aka samar a coils (coils, coils) ko a cikin wani nau'i na tef. A gicciye sashe na wani nichrome waya na iya zama a cikin nau'i na wani m, mai da'ira, wani square da wani trapezoid, da diamita ne a cikin kewayon daga 0.1 zuwa 1 millimeter.

Inda muka samu ko saya kayayyakin daga nichrome? Mun bayar da shawarar a yi la'akari da mafi yawan na kowa da yiwu zaɓuɓɓuka:

1. Da farko, za ka iya tuntuɓar da kungiyar, samar da wadannan kayayyakin da kuma oda. Gano ainihin adireshin irin kamfanonin na iya zama a cikin na musamman tunani a kan kaya da kuma ayyuka da suke samuwa a kusan dukkanin manyan birane da garuruwa. A sadarwarka zai iya gaya mani inda saya, kuma ba wata lambar waya. Bugu da kari, bayanai game da kewayon wannan kayayyakin za a iya samu a hukuma yanar na masana'antun.
2. Buy Nichrome articles a cikin na musamman Stores iya zama, misali, sayar da rediyo aka gyara, abu don artists kamar "m hannayensu" da sauransu. D.
3. Sayi daga masu zaman kansu mutanen sayar da rediyo sassa, kayayyakin gyara da kuma sauran karfe kayayyakin.
4. A wani hardware store.
5. A cikin kasuwar za ka iya saya wani tsohon naúrar, misali awon rheostat, da kuma daukar Nichrome.
6. Nichrome waya za a iya samunsa a gida. Alal misali, an yi shi daga karkace hotplate.

Idan kana so ka yi wani babban tsari, sa'an nan ya fi dace shi ne na farko da wani zaɓi. Idan kana bukatar wani karamin adadin Nichrome waya, duk wasu jerin abubuwa za a iya gani a wannan harka. Lokacin da ka sayi dole ne ko da yaushe kula da markings.

Nichrome karkace coiling

Yau Nichrome karkace ne mai muhimmanci a kashi na da yawa heaters. Bayan sanyaya Nichrome ne iya kula da plasticity, yin karkace daga irin wannan abu za a iya sauƙi cire ya canza ta da siffar ko, idan ya cancanta, daidaita zuwa dace size. Karkace Winding ne da za'ayi a karkashin m yanayi wani atomatik hanya. A gida, za ka iya kuma gudanar da wani manual Tuddan. Bari mu bincika yadda za a yi da shi.

Idan ba a ma muhimmanci sigogi an gama Nichrome karkace a cikin aiki yanayin, a lokacin da Tuddan iya shirya, saboda haka yin magana, "da ido". Don yin wannan, zabi lambar da ake so na jũya dangane da dumama nichrome waya, da karkace ciki har da lokaci zuwa lokaci zuwa cibiyar sadarwa, da kuma kara ko ragewa yawan jũya. Wannan Tuddan hanya ne mai sauki ba, amma zai iya daukar lokaci mai tsawo, kuma wani ɓangare na Nichrome haka kuka da kansa.

Don inganta sauƙi da kuma daidaito na lissafi na karkace Tuddan, za ka iya amfani da wani musamman online kalkuleta.

Ana kirga da ake bukata yawan jũya ne mai yiwuwa a fara Tuddan a kan sanda. Ba yankan da waya ya kamata a hankali alaka nichrome nada wani irin ƙarfin lantarki Madogararsa. Sa'an nan duba daidaitar da lissafin da karkace Tuddan. Yana da muhimmanci a tuna cewa ga spirals gated Tuddan tsawon da za a karu da daya bisa uku, a cikin lissafi na sakamakon dabi'u.

Don tabbatar da wannan nesa tsakanin m jũya daga Tuddan da za a gudanar a biyu wayoyi - daya nichrome, na biyu - ko dai jan karfe ko aluminum, tare da diamita wanda shi ne daidaita da ake so yarda. Lokacin da Tuddan ne a kan, da karin waya dole ne a hankali iska.

A kudin nichrome

The kawai drawback, wanda yana da wani Nichrome - Farashin. Alal misali, a binary gami lokacin da sayen kiri da aka kiyasta a game da 1,000 rubles da kilogram. A kudin wani ligature alamomi Nichrome - game da 500-600 rubles.

ƙarshe

Tare da samar da nickel-chromium, shi wajibi ne don la'akari da bayanan a kan sinadaran abun da ke ciki na samfurin ban sha'awa, kuma ta lantarki juriya, da jiki da halaye na diamita, giciye-sashe, tsawon da sauransu. D. Yana da muhimmanci a tambayi dacewa takardun. Har ila yau, kana bukatar ka iya gani rarrabe shi daga gami, sai su yi magana, "fafatawa a gasa". Proper abu selection ne key lantarki AMINCI.
