E like me kā mākou e ʻike ai, loaʻa i nā metala āpau ka hanana kūlohelohe ʻo Corrosion. ʻO ke kila kahi hale kūkulu maikaʻi i mākaukau koke ia, hoʻohana hou ʻia a loaʻa kahi lakio ikaika-i-kaupaona kiʻekiʻe a me ka lōʻihi o ka lōʻihi, akā naʻe, ʻaʻole hiki ke pale ʻia. Hiki i ke aʻa kila ke hoʻēmi i kona ikaika, palakiko, paʻakikī a me nā pono mechanical, e luku hoʻi i ka geometry kila, hoʻopōkole i ka hāpai lawelawe, a pēlā i nā hale, nā alahaka, nā alanui, nā dyke-dams a me nā hana ʻē aʻe e pili ana i nā mea kila e lawe mai i nā mea palekana. . I mea e hōʻino ai i nā pilikia rusting, ʻo ka hao iā mākou e heʻe pinepine ana a i ʻole hoʻomaikaʻi pinepine ʻia ka hale, i hiki ai i ka hoʻonui ʻana o ke kumukūʻai hana a mālama kālā paha, maikaʻi ʻole ia a ʻoluʻolu ʻole ʻole ke ʻano.
I kēia manawa he hoʻomohala hou, a kūlohelohe 0 mea hoʻohaumia - basalt fiber hiki ke hoʻonā i ka pilikia ka popopo. Hana ʻia ka fiber basalt mai ka pōhaku basaltic basalt e ka hoʻoheheʻe ʻana i ka mahana kiʻekiʻe a me ka ʻōhū. No ka mea mai ka pōhaku lua pele maoli a haku ʻia ʻo SiO2, Al2O3, CaO, MgO, TiO2, Fe2O3 a me nā oxide ʻē aʻe. Hoʻohui ʻia, hoʻoholo kāna hana hana e hana i nā ʻōpala liʻiliʻi, a hiki ke hoʻohaʻahaʻa pololei ʻia ka huahana i hoʻonele ʻia i ke kaiapuni me ka ʻole o kahi ʻino. No laila, he ʻōmaʻomaʻo ʻōmaʻomaʻo a me ka pilina o ka nohona.
Ma muli o kāna kūpaʻa kūlohelohe a me nā waiwai kemika, he hana kūlohelohe maoli ka basalt fiber: ikaika kiʻekiʻe, pale i ka pala, pale aku i ka popo, a pale aku i ka alkali a me ka waikawa, ʻaʻohe conductive a me thermal insulation. No laila hiki ke hoʻohana pololei ʻia ka pulupulu basalt i kēlā me kēia wahi me ka ʻole o ka mālama ʻana o ka honua a me ka mālama ʻole ʻia, e mālama nui ai ke kālā.
E lawe i basbar rebar ma ke ʻano he laʻana, i hana ʻia i ka fiber basalt e ka ʻenehana pultrusion a ʻelua mau manawa ʻoi aku ka ikaika o ka ikaika ma mua o ke kila kila a me 1/4 kaupaona o ke kila kila, a ke pale aku nei ia i ka alkali a pale aku i ka popopo, i kekahi noi, hiki i ka basbar rebar ke e kuapo i ka fiberglass rebar a me ka hao rebar.
Kuhi ʻia ka mākeke fiber Basalt a hiki i 112 Million USD ma 2017. E hoʻomaka mākou e hoʻohana i ka mea ʻaʻohe popopo i kēia manawa.
