I ka uila, hana koʻikoʻi nā resistors i ka mālama ʻana i ke kahe o kēia manawa. He ʻāpana koʻikoʻi lākou i nā mīkini mai nā kaapuni maʻalahi a i nā mīkini paʻakikī. ʻO nā mea i hoʻohana ʻia no ka hana ʻana i nā resistors e pili nui i kā lākou hana, lōʻihi a me ka pono. Ma waena o lākou, he mea hoihoi nui ka hao-chromium-aluminum, nickel-chromium alloys, a me ka copper-nickel alloys ma muli o ko lākou mau waiwai kūikawā.
No ke aha he mea koʻikoʻi nā alloys i ka hana resistor
ʻO nā Alloys nā hui ʻelua a ʻoi aku paha, ʻo ka liʻiliʻi hoʻokahi o ia mea he metala. Hoʻolālā ʻia lākou e hoʻomaikaʻi i nā waiwai kikoʻī e like me ka ikaika, ke kūpaʻa corrosion a me ke kūpaʻa wela. I nā noi resistor, pili ka koho o ka alloy i ka coefficient mahana, kūpaʻa a me ka hana holoʻokoʻa o ka resistor.
He aha nā waiwai koʻikoʻi o nā alloys i hoʻohana ʻia i nā resistors
(1) Kū'ē: ʻO ka hana mua o kahi mea pale e hāʻawi i ke kū'ē i ke kahe o kēia manawa. ʻO ka resistivity o ka alloy he kumu nui i ka hoʻoholo ʻana i kona pono i ka hana ʻana i kēia hana. 2.
(2) Hōʻuluʻulu Manaʻo: Hōʻike kēia waiwai i ka nui o ke kūʻē ʻana o kekahi mea me ka wela. Pono nā mea pale i kahi helu haʻahaʻa haʻahaʻa o ke kūpaʻa e hōʻoia i ka hana paʻa ma luna o kahi ākea ākea.
(3) Kū'ē Kū'ē: Hōʻike pinepineʻia nā mea pale i nā wahi paʻakikī. ʻO nā huila e kūʻē i ka oxidation a me ka corrosion he mea nui i ka mālama ʻana i ke ola a me ka hilinaʻi o ka resistor.
(4) Mechanical Strength: Pono nā mea pale e kū i ke koʻikoʻi kino a me ke kaʻa kaʻa wela. Hiki i nā Alloys me ka ikaika mechanical kiʻekiʻe ke kū i kēia mau kūlana me ka ʻole o ka degradation.
(5) Thermal Stability: He mea koʻikoʻi ka hiki o kahi huila e mālama i kona mau waiwai i nā mahana kiʻekiʻe, ʻoi aku ka nui o nā noi mana kiʻekiʻe.
Iron Chromium Aluminum Alloy - Hoʻohui a me nā waiwai:
ʻO nā mea hao-chromium-aluminum(FeCrAl) ʻike ʻia no ko lākou kūpaʻa ʻana i ka oxidation maikaʻi a me ke kūpaʻa kiʻekiʻe. ʻO ka mea maʻamau i haku ʻia me ka hao, chromium a me ka aluminika, ʻaʻole e hoʻohaʻahaʻa nui kēia mau alaleʻa i nā mahana a hiki i 1400°C (2550°F).
Nā noi i loko o nā mea pale:
Hoʻohana nui ʻia nā mea hao-chromium-aluminum i nā resistors kiʻekiʻe, ʻoi aku ka nui o nā noi:
- Nā Mea Hoʻomaʻamaʻa: Hoʻohana maʻamau ʻia nā ʻāpana hao Chromium Aluminum e like me nā mea hoʻomehana i nā kapuahi ʻoihana a me nā umu ma muli o ko lākou hiki ke mālama pono i ka hoʻolālā ʻana i nā wela kiʻekiʻe.
- Nā mea pale mana: Hoʻohana pū ʻia kēia mau ʻāpana i nā mea pale mana e koi ai i ke kūpaʻa wela kiʻekiʻe a me ke kū ʻana o ka oxidation.
- Nā noi kaʻa: Ma nā mea uila uila, hoʻohana ʻia nā alloys FeCrAl i nā mea pale e hana ana i nā wahi wela kiʻekiʻe, e like me nā ʻōnaehana exhaust.
Nickel-Chromium Alloys - Hoʻohui a me nā waiwai:
ʻO nā alloys Nickel-chromium (NiCr) kekahi koho kaulana no nā noi pale. Hoʻokumu ʻia kēia mau alloys me ka nickel a me ka chromium, ʻo ka pākēneka o ia mau mea e pili ana i nā ʻano i makemake ʻia.Nā huila NiCrʻike ʻia no ko lākou kūpaʻa maikaʻi loa, ka hana wela kiʻekiʻe a me ke kūpaʻa corrosion.
Hoʻohana pinepine ʻia nā alloys Nichrome:
- Film Resistors: Hoʻohana ʻia kēia mau mea pale i nā noi kahi i koʻikoʻi ai ka pololei a kahi e hāʻawi ai ʻo NiCr alloy i ka paʻa pono a me ka coefficient wela haʻahaʻa.
- Wirewound Resistors: I ka wirewound resistors, hoʻohana pinepine ʻia ka uea Nichrome ma muli o kona kūpaʻa kiʻekiʻe a me ka hiki ke kū i ka paikikala wela.
- Nā noi kiʻekiʻe kiʻekiʻe: E like me ka ferrochromium-aluminum alloys, kūpono nā nickel-chromium alloys no nā wahi wela kiʻekiʻe, e hoʻolilo iā lākou i mea kūpono no nā noi ʻoihana a me ka aerospace.
Copper-nickel alloys - haku mele a me nā waiwai
Ua ʻike ʻia nā alloy copper-nickel (CuNi) no kā lākou conductivity uila maikaʻi loa a me ke kūpaʻa corrosion. Loaʻa i kēia mau ʻāpana ke keleawe a me ka nickel, me nā waiwai kikoʻī i loaʻa ma ka hoʻololi ʻana i ka ʻike nickel. Hoʻohanohano nui ʻia nā alloy CuNi no ko lākou hiki ke mālama i ka hana ma ka moana a me nā wahi corrosive ʻē aʻe.
Hoʻohana ʻia nā ʻāpana keleawe-nickel i nā ʻano noi resistor, e like me:
- Precision Resistors: Ma muli o kā lākou conductivity maikaʻi a me ka paʻa,Nā huila CuNiHoʻohana maʻamau ʻia no nā resistors pololei i ke ana ʻana a me nā noi hoʻomalu.
- Nā noi moana: ʻO ke kūpaʻa corrosion o nā huila CuNi e kūpono iā lākou no nā mea pale i hoʻohana ʻia i nā kaiapuni moana kahi e hiki ai ke hōʻeha i ka wai paʻakai.
- Nā noi haʻahaʻa haʻahaʻa: Hana maikaʻi nā huila keleawe-nickel i nā kaiapuni cryogenic, e hoʻolilo iā lākou i mea kūpono no nā noi haʻahaʻa haʻahaʻa.
ʻO FeCrAl, nichrome, a me ka copper-nickel alloys he mau waiwai kūʻokoʻa lākou e kūpono ai no nā ʻano hana like ʻole.
- Hana maikaʻi nā mea hao-chromium-aluminum i nā wahi wela kiʻekiʻe a kūpono i nā mea hoʻomehana a me nā mea pale mana.
- Hāʻawi ka Nickel-chromium alloys i ke kūpaʻa maikaʻi loa a me ka pale ʻana i ka corrosion a kūpono i nā mea pale kiʻiʻoniʻoni a me nā wirewound.
- Ua ʻike ʻia nā ʻāpana keleawe-nickel no ko lākou conductivity kiʻekiʻe a me ke kūpaʻa ʻana i ka corrosion a kūpono hoʻi no nā resistors precision a me nā noi moana.
