Nichromeʻoni iho: ka waiwai a me ka palapala noi

Hoikehonua, ola mea hiki ole ke manao wale me ka nui helu o okoa nā mīkini home. No ka nui o ia Nichromeʻoni iho o ka papa kuhikuhiE hapa - ka "naau" o keʻano papa hana. I ka lolouila pono, mīkini hana, mana mea paahana hoʻohana i ka maʻamau o ke ola, a ma ka nui-unahiʻole, i? Iecaianoaaiiie, Ua pololei e kaukaʻi ma ka uea me ka mea mua oka a pau.

hōʻikeʻano

I ka 1905, 'Amelika nä känaka' epekema Albert Marsh dala e hui pu iho chromium a me ka nikala. Ka Palapala Sila Nui haʻilula like penei 20% chromium a me 80% nikala. Ke oka a pau i ka inoa o - nichrome. Initially, uaʻaʻohe ligation (refractory hehee wale) i loko o ka läÿau, a me ka mea, ua he mau-ke keʻena oka a pau. I kēia lā e mea hiki ke loaʻa Lolina me ka nikala maʻiʻo o 55% a me ka chromium 15%. Impurities i hao, silikone, manganese, Aluminum, titanium, molybdenum, silikone. Aia, ua oi aku mamua o umi "ideas" metala haule ma lalo o ka inoa o ka nichrome.

Nichromeʻoni iho me ka loa kiʻekiʻe resistivity ua lilo i paʻa ke keʻena o na mea paahana a me nā mea paʻahana a. He hiki no withstanding kiʻekiʻe ana wela'okesaside i ka maʻamau, a me ka corrosive hana kūpono. Kēia oka a i kekahi waiwai ku i ke alo o ka chromium, a ano ma ka ili o ka 'atikala i ka aiiay'okesaside ho film. Ua pena i ka oka a pau i loko o ka uliuli. Inā e wehe i (ma mechanical e hana) oxidized, ahu iho, tint loli i ka whitish poʻo.

Y aeaie oka a iʻume mākenēki waiwai, multicomponent ka hoʻololi 'ana i ke attenuated kiko'î. Nichromeʻoni iho ka haka a me ka maikai ductility. Uea ua ua hanaʻia me ka okoa pauku mai 0,01 a hiki i 10 mm o. Key hiʻona nā:

• uila resistivity - OM`m 1100-1400;
• mahele heheʻe i ka wahi i 1400 degere (ka hana huahelu - 800-1100 kekelē Kelekia ma);
• nuʻa - 8200-8500 kg / ka m ^3;
• ikaika - 650-700 MPa.

Material waiwai halawai pu me ka mea kiekie loaʻanoʻenehana koi.

pono

Kiekie a me ka ikaika koi no eiiiiiaiou mai Nichrome oka mea ku pono i ka mea kupaianaha ano:

• ole malalo i ka popopo;
• haahaa ke kaupaona;
• oluolu i ka kaʻina (hoopuni kuʻi ihola, a welded);
• Ua loaʻa kiʻekiʻe wela e kū'ē'ē mai;
• mau nō a me ka'ōlewa i ka ia manawa;
• wehewehe aku e mahuahua ia'ku iʻano pākīkē hana kūpono;
• He He He lōʻihi hana ola.

Kekahi mea nui ka pono i ka mea kiʻekiʻe ia'ku i ka pilaʻikena. Ma ka hana pono, i kēia aiao e leie aku no ka poʻeʻuʻuku Nichrome (Nichromeʻoni iho pōkole lōʻihi) e loaa hou wela ma mua o ana, no ka mea hoike, i ke kila lālā. I huli ai oe, he uuku ka nui o ka metala ke emi ke kaumaha a me ka nui o ka nakeke holoʻokoʻa. Ke kumu nui ia Morohiha o nichrome - he huihui 'ana o nā mea a pau o kēia mau metrics i loko o ka ia mea.

Nichromeʻoni iho hiki ke i ka likeʻole ka hoʻololi 'ana o ka oka a pau, a ia o kekahi mānoanoa. A hehi ihola au i okoa i loko o kā lākou haku mele 'ana, a ua māheleʻia (conditionally) i loko o ka papa kuhikuhiE pūʻulu ekolu:

• Mea pale mū holapū: H20N80 (20% chromium, 80% nikala); H20N73YUM-VI (20% chromium, 73% nikala, 3% Aluminum, 1.5% molybdenum, mai ia 0,3% manganese, i ka 0,05% titanium, 2% hao, mai ka 0,05% o carbon , maule iho la holo hoʻokomo iaoia).
• No ka hoʻohana ma ke anawela ma luna o 900 degere.
• No ka paio hahana maoli nō nā kumumea me mahuahua ia'ku i kiʻekiʻe Mahana O Ke Kai: HN70YU-H (27% chromium, 70% nikala, 3% Aluminum, mai ia 0,3% manganese, i ka 0,03% o ka cesium, a 0,1% o ka barium a me ka 1, 5% hao, mai ia 0,1% kalapona).

Ma ka huliāmahi o kona constituent eiiiiiaiou, waiwai o ka oka a hilinai nei. A nui helu o ka chromium ua ālai ''okesaside.

Mawaena o ka loa i imi ai ma hope o nichrome uea lako e pili i ka pou huahana market. Helix o keia oka a ua hoʻohana 'ia i loko o nā Ke Ana Hoʻohālike o ka pila heaters. poe paahana e hana ia ma ka hale no ka:

• i hoʻomākaukauʻia e aa laau;
• homemade umu no ka hoʻolele pālolo;
• kokololio paio hahana maoli nō manao maalea o kekahi mea hiki ke hooheheeia ma ka smithy;
• hua paio hahana maoli nō simplest manao ( "kao");
• homemade welders.

Ka hanalima ana o ka nikala chromium i loko o ka hale o nā mīkini home kaiāulu: lauoho dryers, ka hao, heaters, soldering ka hao, uila, a no laila, ma luna o. Uea me ka nui keʻa-pauku ua hoʻohana 'ia no ka' akomi kuʻihao noi. Oia ka oka a hiki ke loaʻa ma ka keʻena hoʻokolohua lako a pan a me ka uila kahua. Nichrome uea ua hoʻohana 'ia kahi koi ia'ku i kiʻekiʻe ana wela a me ka corrosive hana kūpono.
