No ka uea kū'ē, hiki ke hoʻoholo i ka mana o kā mākou kū'ē e like me ke kū'ē o ka uea kū'ē. ʻO ka nui o kona mana, hiki i nā poʻe he nui ke ʻike ʻole i ke koho ʻana i ka uea kūʻē, a ʻaʻole nui ka ʻike e pili ana i ka uea kūʻē. , E wehewehe ʻo Xiaobian i nā mea a pau.

ʻO ka uea kūʻē ke ʻano maʻamau o ka mea wela. ʻO kāna hana ʻo ia ka hoʻoulu ʻana i ka wela ma hope o ka hoʻoulu ʻana a hoʻololi i ka ikehu uila i ka wela. ʻO ka uea kū'ē he nui nā noi. Nui nā mea hoʻomehana uila i hoʻohana mau ʻia e hoʻohana i ka uea kūʻē ma ke ʻano he mea hoʻomehana. No laila, hoʻohana ʻia ka uea kūʻē i ka lāʻau lapaʻau, kemika, uila, uila, metallurgical machinery, ceramic glass processing a me nā ʻoihana ʻē aʻe.

1. ʻO ke kumu hana o ka uea kū'ē

ʻO ke kumu hana o ka uea kūʻē e like me nā mea hoʻomehana metala ʻē aʻe, a ʻo ia ka mea hoʻomehana uila ma hope o ka hoʻoikaika ʻana o ka metala. ʻO ka hoʻomehana uila ʻo ia hoʻi, ma hope o ke kahe ʻana o ke au i ka conductor, e hoʻohua ka ʻāwī i kekahi nui o ka wela a hoʻololi ʻia e ka conductor. ʻO ka uea kūʻē ponoʻī he mea hoʻokele metala, nāna e hoʻokuʻu i ka wela a hāʻawi i ka ikehu wela ma hope o ka hoʻoikaika ʻana.

2. Ka hoʻokaʻawale ʻana o ka uea kūʻē

Hoʻokaʻawale ʻia nā ʻano o ka uea kūʻē e like me ke ʻano o ka mea kemika a me ka hoʻonohonoho hoʻonohonoho ʻana o ka uea kūʻē. Aia nā uea kū'ē iron-chromium-aluminum a me nickel-chromium alloy resistance wires. E like me nā mea hoʻomehana uila, ʻokoʻa nā hiʻohiʻona hana o kēia mau ʻano uea kūʻē.

3. nā hiʻohiʻona o ka uwea kū'ē

Hōʻike ʻia ka uea kūʻē e ke kiʻekiʻe o ka wela, ka hoʻomehana wikiwiki, ka lōʻihi o ka lawelawe ʻana, ke kūpaʻa kūpaʻa, ka liʻiliʻi liʻiliʻi liʻiliʻi, ke kau ʻana o ka thread pitch ma hope o ka hoʻolōʻihi ʻana, a me ka mālamalama a me ka maʻemaʻe. Hoʻohana nuiʻia ia i nā kapuahi uila liʻiliʻi, nā kapuahi muffle, nā mea hoʻomehana a me nā ea, nā umu likeʻole, nā paipu hoʻomehana uila a me nā mea hana hale, a me nā mea'ē aʻe.

4. nā mea maikaʻi a me nā pōʻino o ka hao-chromium-aluminum alloy resistance wire

ʻO ka uea pale pale hao-chromium-aluminum i ka pono o ka wela hana kiʻekiʻe. Hōʻike ka hoʻokolohua e hiki ke piʻi i ka 1400 ° C ka mahana hana kiʻekiʻe loa o ka uea pale pale hao-chromium-aluminum. ʻO ka hao-chromium-aluminum alloy resistance uea he lōʻihi ke ola o ka lawelawe ʻana, ka resistivity kiʻekiʻe, ka hoʻohuihui ʻili kiʻekiʻe, a me ke kūpaʻa oxidation maikaʻi.

ʻO ka hemahema o ka uwea pale pale hao-chromium-aluminum i kona ikaika haʻahaʻa ma nā wahi wela kiʻekiʻe. I ka piʻi ʻana o ka mahana, e hoʻonui ʻia ka plasticity o ka hao-chromium-aluminum alloy resistance wire, ʻo ia hoʻi, ʻo ka hao-chromium-aluminum alloy resistance uea he prone i ka deformation i nā wela kiʻekiʻe. A ʻaʻole maʻalahi ka hoʻoponopono ʻana ma hope o ka deformation.

5. nā pono a me nā pōʻino o ka nickel-chromium alloy resistance wire

ʻO nā mea maikaʻi o ka nickel-chromium alloy resistance wire he ikaika kiʻekiʻe i ke kaiapuni kiʻekiʻe, ʻaʻole maʻalahi ka hana ʻana o ka mahana wela lōʻihi, a ʻaʻole maʻalahi ke hoʻololi i ke ʻano, a me ka plasticity maʻamau o ka nickel-chromium alloy resistance. Ua maikaʻi ka uea, a he maʻalahi ka hoʻoponopono ʻana ma hope o ka deformation. Eia kekahi, ʻo ka nickel-chromium alloy resistance wire he kiʻekiʻe emissivity, non-magnetic, maikaʻi corrosion kū'ē a me ka lōʻihi lawelawe ola.

ʻO ka hemahema o ka uwea pale nickel-chromium alloy ʻaʻole hiki i ka mahana hana ke hiki i ke kiʻekiʻe o ka uea kūʻē mua. Pono ka hoʻohana ʻana i ka nickel-chromium alloy resistance wire i ka hana ʻana i ka nickel. ʻOi aku ke kumukūʻai o kēia metala ma mua o ka hao, chromium a me ka alumini. No laila, ʻoi aku ka kiʻekiʻe o ke kumukūʻai o ka nickel-chromium alloy resistance wire, ʻaʻole kūpono i ka hoʻokele kumukūʻai.
