conductivity o ke keleawe
ʻO kekahi o nā waiwai nui loa okeleawe kepau ʻoleʻo ia ka maikaʻi o ka conductivity uila, me ka conductivity o 58m/(Ω.mm square).Hana kēia waiwai i ke keleawe i hoʻohana nui ʻia i nā ʻoihana uila, uila, kelepona a me nā ʻoihana uila.Ua pili kēia conductivity uila kiʻekiʻe o ke keleawe i kona ʻano atomika: ke hui ʻia nā ʻātoma keleawe he nui i loko o kahi poloka keleawe, ʻaʻole paʻa ko lākou mau electrons valence i nā ʻātoma keleawe, no laila hiki iā lākou ke neʻe manuahi i loko o nā keleawe paʻa a pau., ʻo kona conductivity ka lua wale nō ma mua o ke kālā.ʻO ke kūlana honua no ka conductivity o ke keleawe ʻo ia ka conductivity o ke keleawe me ka lōʻihi o 1m a me ke kaumaha o 1g ma 20 ° C ʻike ʻia he 100%.Ua hiki i ka ʻenehana hoʻoheheʻe keleawe i kēia manawa ke hana i ka pae like o ke keleawe me ka conductivity 4% a 5% kiʻekiʻe ma mua o kēia kūlana honua.
ʻO ka hoʻoili wela o ke keleawe
ʻO kekahi hopena koʻikoʻi o nā electrons manuahi i ke keleawe paʻa he kiʻekiʻe kiʻekiʻe ka thermal conductivity.ʻO 386W/(mk) kona conductivity wela, ʻo ia ka lua o ke kālā.Eia kekahi, ʻoi aku ka nui a ʻoi aku ka maikaʻi o ke keleawe ma mua o ke gula a me ke kālā, no laila ua hana ʻia i nā huahana like ʻole e like me nā uea a me nā kaula, nā terminal connector, nā kaʻa kaʻa, nā papa alakaʻi, a me nā mea ʻē aʻe, i hoʻohana nui ʻia i ka uila a me ka uila, kelepona. a me nā ʻoihana uila.He mea koʻikoʻi nō ke keleawe no nā mea hoʻololi wela e like me nā mea hoʻololi wela, condensers, a me nā radiators.Hoʻohana nui ʻia ia i nā mīkini kōkua o ka mana, nā ea, ka pahu hau, nā pahu wai kaʻa, nā kolamu o ka lā, ka desalination o ke kai a me ka lāʻau lapaʻau, ʻoihana kemika., metallurgy a me nā manawa hoʻololi wela ʻē aʻe.
ʻO ka pale ʻana o ke keleawe
ʻOi aku ka maikaʻi o ka corrosion i ke keleawe, ʻoi aku ka maikaʻi ma mua o ke kila maʻamau, a ʻoi aku ka maikaʻi ma mua o ka alumini i ka lewa alkaline.ʻO ke kaʻina o ke keleawe he +0.34V, ʻoi aku ka kiʻekiʻe ma mua o ka hydrogen, no laila, he metala me kahi kūpono kūpono.He haʻahaʻa loa ka pōʻino o ke keleawe i loko o ka wai hou (ma kahi o 0.05mm/a).A i ka wā e hoʻohana ʻia ai nā paipu keleawe no ka lawe ʻana i ka wai paipu, ʻaʻole waiho nā paia o nā paipu i nā minerala, kahi mamao loa ma mua o ka hiki ʻana o nā paipu wai hao.Ma muli o kēia hiʻohiʻona, hoʻohana nui ʻia nā paipu wai keleawe, nā faucets a me nā mea pili i nā lako lako wai ʻauʻau kiʻekiʻe.Paʻa loa ke keleawe i ka ʻino o ka lewa, a hiki iā ia ke hana i kahi kiʻiʻoniʻoni pale i haku nui ʻia me ka keleawe keleawe ma luna o ka ʻili, ʻo ia hoʻi ka patina, a ʻo kāna haku mele CuS04*Cu(OH)2 a me CuSO4*3Cu(OH)2.No laila, hoʻohana ʻia ke keleawe no ke kūkulu ʻana i nā panela o ka hale, nā paipu ua, nā paipu luna a lalo, a me nā paipu paipu;nā pahu kemika a me ka lāʻau lapaʻau, nā reactors, nā kānana pulp;lako moku, propellers, ola a me na paipu ahi;nā ʻāpana kuʻi (corrosion resistance) ), hoʻonani, mekala, trophies, kiʻi kiʻi a me nā mea hana lima (corrosion resistance a me ke kala nani), etc.
