ʻO ka pā keleawe me nā hiʻohiʻona mālama maikaʻi

Pāpā keleaweʻo ia kekahi o nā mea hoʻohui metala i ʻike ʻia e nā mea a pau, a ʻo ia kekahi o nā mea metala maʻemaʻe maikaʻi loa.He paʻakikī iki, ʻoʻoleʻa loa, ʻaʻahu-pale a loaʻa ka ductility maikaʻi.Eia kekahi, ʻoi aku ka maikaʻi o ka lawe ʻana i ka wela a me ka conductivity uila.ʻAe, maʻalahi loa ka hana ʻana o nā ʻano o ka pā keleawe.Ke hoʻohālikelike ʻia me ka hao a me ka aluminika, ʻo nā pā keleawe he mau mea maʻamau, a ʻo nā pā keleawe he mau hiʻohiʻona mālama kiʻekiʻe.

Nui nā waiwai kino o nā pā keleawe.ʻO ka mea koʻikoʻi, ʻoi aku ka nui o kāna conductivity uila ma mua o nā mea hana metala ʻē aʻe a me ka hao, ʻoi aku i ke kālā wale nō.Pēlā nō, ʻoi aku ka nui o kona hoʻoili wela ma mua o nā mea metala ʻē aʻe koe ke kālā.Paʻa loa nā pā keleawe maʻamau i ka corrosion, e like me ka mea i hōʻoia ʻia e ko lākou hoʻohana ʻana i ka hana hale a me nā hana noʻeau no nā kaukani makahiki.
Ke hōʻike ʻia ka pā keleawe i ka ea no kekahi manawa, e loaʻa ana ka oxidation.E hana ʻia kahi kiʻi keleawe ʻōmaʻomaʻo māmā ma ka ʻili.Ke hoʻokumu ʻia ke kiʻiʻoniʻoni plastik, e loaʻa iā ia kahi hopena pale i ka composite metala kūloko.He kūpaʻa ka pā keleawe kūikawā i ka sodium citrate a me ka alkali (koe wale ka sodium hydroxide solution), no laila hiki ke kanu ʻia ma lalo o ka lepo a komo i loko o ka wai me ka maʻalahi ʻole o ka ʻino.
Hoʻohui ka pā keleawe i nā pono he nui.Loaʻa iā ia ka paʻakikī kiʻekiʻe o nā mea metala maʻamau.I ka manawa like, ʻoi aku ka maʻalahi o ke kulou, wili, ʻāhaʻi, a haki ma mua o nā mea metala maʻamau.Loaʻa iā ia kekahi mau anti-swelling a me ka hopena hopena.No laila, i ka manawa i hoʻokomoʻia ai nā'āpana keleawe i loko o nā lako wai i loko o ka hale, hiki ke hoʻohana ponoʻia, me ka mālamaʻole a me ka mālama.ʻO ka mea aʻe e hōʻike pōkole ana i nā pono o ka hoʻohana ʻana i nā pā keleawe me nā kikoʻī.
Loaʻa i ke keleawe nā hiʻohiʻona o nā mea paʻakikī, ʻaʻole maʻalahi i ka ʻino, pale i ka wela a me ke kaomi kiʻekiʻe, a hiki ke hoʻohana ʻia i nā wahi like ʻole.ʻO ka ʻokoʻa, ʻike ʻia nā hemahema o nā mea hoʻopili paipu ʻē aʻe.ʻO kahi laʻana, ʻo nā paipu galvanized i hoʻohana mau ʻia i nā hale i ka wā ma mua he maʻalahi loa ka pala, a ʻo nā pilikia e like me ka melemele o ka wai inu a me ka emi ʻana o ka wai kahe e hiki mai ana ma hope o ka manawa pōkole o ka hoʻohana ʻana.Aia kekahi mau mea e emi koke ana ka ikaika compressive i nā wela kiʻekiʻe, kahi e hoʻopilikia ai i ka pilikia ke hoʻohana ʻia no nā paipu hoʻomehana, a hiki i ka helu heheʻe o ke keleawe i 1083 degere Celsius, no laila ʻaʻohe mea koʻikoʻi ka mahana o ka ʻōnaehana wai paila. kala keleawe.I kēia manawa, hoʻohana pinepine ʻia ʻo ia e like me nā ʻāpana keleawe no nā mea hana hale, nā ʻāpana keleawe no ka refrigeration, nā ʻāpana keleawe kiʻekiʻe, nā ʻāpana keleawe kūpaʻa ʻole, nā ʻāpana keleawe no ka hoʻopili ʻana, nā ʻāpana keleawe no nā ala wai, nā ʻāpana keleawe hoʻomehana uila, a me nā ʻāpana keleawe ʻoihana. .
