Hiki i nā mea hoʻopau paʻa ke pōmaikaʻi mai ka hoʻololi ʻana i nā mea hana lima ma ka zinc mai ke keleawe.Hoʻokūkū nā mea ʻelua i kekahi i kekahi ma ke ʻano o ka paʻakikī, ka lōʻihi, ka hoʻolālā maikaʻi a me ka hoʻopau ʻoihana-akā he mau pono hou ka zinc.
ʻO nā mea hana keleawe he ala hilinaʻi e hoʻokō ai i nā ʻaoʻao radius a me nā ʻāpana hoʻomalu pololei i loko o ke kaʻa.Loaʻa i kona ʻano paʻa ka hāʻawi ʻana i ke kaumaha kūpono a hiki ke hāʻawi i nā hopena maikaʻi ʻoihana.No kēia kumu, ʻo nā mea hana keleawe ke kumu o ka nui o nā mīkini hoʻopau.Eia naʻe, hiki mai kēia makemake i kahi kumukūʻai.ʻO nā kumukūʻai kālā a me nā hana hana o ka hana keleawe e hoʻopau i ka ʻoihana, akā ʻaʻole pono ia.Aia kekahi mea ʻē aʻe i loaʻa-zinc.
ʻOiai ʻokoʻa kā lākou haku mele ʻana, ʻo ke keleawe a me ka zinc nā waiwai like.Hoʻokūkū lākou kekahi i kekahi ma ke ʻano o ka paʻakikī, ka lōʻihi, ka hoʻolālā maikaʻi a me nā hopena lapaʻau ʻoihana.Eia nō naʻe, loaʻa i ka zinc kekahi mau pono ʻē aʻe.
Hoʻemi ka hana Zinc i ke kaumaha o nā mea hana a me nā mea hana.No kēlā me kēia mea hana keleawe i hana ʻia, hiki i ʻelua mau mea hana zinc ke pani.Hoʻemi kēia i ka nui o ke kālā i hoʻopau ʻia ma nā mea hana e hāʻawi i nā hopena like.Eia kekahi, ʻoi aku ka palekana o ka hana a ka mea hana.Ma ka hoʻololi ʻana i ka makemake mākeke i ka zinc, e pōmaikaʻi nā mea ʻaelike a me nā mea hana.
ʻO ka nānā pono ʻana i ka haku mele e hōʻike ʻia he keleawe keleawe i hoʻohana ʻia ma mua o 5,000 mau makahiki.I loko o ka wā koʻikoʻi o ka Bronze Age, ʻo ia ka mea paʻakikī a ʻoi aku ka maikaʻi o ka metala maʻamau i ʻike ʻia e ke kanaka, e hana ana i nā mea hana ʻoi aku ka maikaʻi, nā mea kaua, nā mea kaua a me nā mea ʻē aʻe e pono ai ke ola kanaka.
ʻO ka maʻamau ka hui pū ʻana o ke keleawe a me ka tin, alumini a i ʻole nickel (a me nā mea ʻē aʻe).ʻO ka hapa nui o nā mea hana paʻa he 88-90% keleawe a me 10-12% tin.Ma muli o kona ikaika, paʻakikī a me ka ductility kiʻekiʻe loa, kūpono kēia ʻano no nā mea hana.Hāʻawi kēia mau hiʻohiʻona i ka hiki ke halihali haʻahaʻa, ke kūpaʻa abrasion maikaʻi a me ka lōʻihi kiʻekiʻe.ʻO ka mea pōʻino, hiki nō hoʻi i ka corrosion.
Inā ʻike ʻia i ka nui o ka ea, e oxidize nā mea hana keleawe a lilo i ʻōmaʻomaʻo.ʻO kēia'ōmaʻomaʻo'ōmaʻomaʻo, i kapaʻia he patina,ʻo ia ka hōʻailona mua o kaʻaʻahu.Hiki i ka patina ke hana ma ke ʻano he pale pale, akā inā loaʻa nā chlorides (e like me nā mea i loko o ka wai kai, lepo a wela paha), hiki i kēia mau mea hana ke ulu i "maʻi keleawe".ʻO kēia ka pau ʻana o nā mea hana kīʻaha (copper-based).He ma'i lele hiki ke komo i ke metala a luku.Ke hana ʻia kēia, ʻaneʻane ʻaʻohe manawa e hoʻōki ai.
Aia ka mea hoʻolako zinc ma ʻAmelika Hui Pū ʻIa, e kaupalena ana i ka hana outsourcing.ʻAʻole wale kēia i lawe mai i nā hana ʻenehana hou aku i ʻAmelika Hui Pū ʻIa, akā ua hoʻemi nui ʻia nā kumukūʻai hana a me ka waiwai kūʻai.MARSHALLTOWN hui
No ka mea ʻaʻole i loko o ka zinc ke kīʻaha, hiki ke pale ʻia ka "maʻi keleawe".ʻO ka mea ʻē aʻe, he mea metala ia me kona huinahā ponoʻī ma ka pākaukau manawa a me kahi ʻano aniani hexagonal pani piha ʻia (hcp).Loaʻa iā ia ka paʻakikī paʻakikī, a hiki ke hana malleable a maʻalahi hoʻi e hana ma kahi mahana i ʻoi aku ka kiʻekiʻe ma mua o ka wela ambient.
I ka manawa like, ʻo ka keleawe a me ka zinc ka paʻakikī i kūpono loa i nā mea paahana (ma ka paʻakikī paʻakikī Mohs o nā metala, zinc = 2.5; keleawe = 3).
No ka hoʻopau paʻa, ʻo ia hoʻi, ma ke ʻano o ka haku mele ʻana, he liʻiliʻi ka ʻokoʻa ma waena o ke keleawe a me ka zinc.Hāʻawi nā mea ʻelua i nā mea hana paʻa me ka hiki ke haʻi haʻahaʻa kiʻekiʻe, ke kūpaʻa abrasion maikaʻi, a me ka hiki ke hana i nā hopena hopena like.ʻAʻole like nā hemahema o Zinc-he māmā, maʻalahi ke hoʻohana, kūpaʻa i nā ʻeleʻele keleawe, a me ke kumu kūʻai.
Ke hilinaʻi nei ka hana keleawe ma nā ʻano hana ʻelua (ka hoʻolei ʻana i ke one a me ka hoʻoheheʻe make), akā ʻaʻohe kumu kūʻai no nā mea hana.ʻO ka hopena, hiki i nā mea hana ke hāʻawi i kēia pilikia kālā i nā ʻaelike.
ʻO ka hoʻolei ʻana i ke one, e like me ka manaʻo o ka inoa, ʻo ia ka ninini ʻana i ke keleawe i hoʻoheheʻe ʻia i loko o kahi poni hoʻopau i paʻi ʻia me ke one.No ka mea hiki ke hoʻopau ʻia ka mold, pono ka mea hana e hoʻololi a hoʻololi paha i ka mold no kēlā me kēia mea hana.Pono kēia kaʻina hana i ka manawa, ʻo ia ka mea e liʻiliʻi ai nā mea hana i hana ʻia a hopena i nā kumukūʻai kiʻekiʻe no nā mea keleawe keleawe no ka mea ʻaʻole hiki i ka lako ke hoʻokō i ka koi mau.
Ma ka ʻaoʻao ʻē aʻe, ʻaʻole hoʻokahi wale nō ka hoʻolei ʻana.I ka manawa e ninini ʻia ai ka metala wai i loko o ka moʻo metala, paʻa a wehe ʻia, mākaukau hou ka ʻōpala no ka hoʻohana koke ʻana.No nā mea hana, ʻo ka hemahema wale nō o kēia ʻano hana ʻo ia ke kumukūʻai o ka pahu hoʻoheheʻe hoʻokahi i hiki ke kiʻekiʻe e like me nā haneli haneli mau kālā.
ʻO ke ʻano o ke ʻano o ka hoʻoheheʻe ʻana e koho ai ka mea hana e hoʻohana, pili ka wili a me ka deburring.Hāʻawi kēia i nā mea hana keleawe i kahi lapaʻau maʻemaʻe, mākaukau a mākaukau hoʻi e hoʻohana.ʻO ka mea pōʻino, pono kēia kaʻina hana i nā koina hana.
ʻO ka wili a me ka deburring kahi ʻāpana koʻikoʻi o ka hana ʻana i nā mea hana keleawe, a e hoʻohua ai i ka lepo e pono ai ka kānana a i ʻole ka ea.Inā ʻaʻole kēia, hiki i nā limahana ke loaʻa i kahi maʻi i kapa ʻia ʻo pneumoconiosis a i ʻole "pneumoconiosis", kahi e hōʻiliʻili ai ka ʻiʻo ʻili i loko o ka māmā a hiki ke hoʻopilikia i ka maʻi maʻi maʻi maʻi.
ʻOiai ʻo kēia mau pilikia olakino ka mea maʻamau i loko o ka māmā, pili pū kekahi mau kino ʻē aʻe.Hiki ke hoʻoheheʻe ʻia kekahi mau mea i loko o ke koko, e ʻae iā lākou e laha a puni ke kino, e pili ana i ke ake, nā puʻupaʻa a me ka lolo.Ma muli o kēia mau kūlana weliweli, ʻaʻole makemake hou kekahi mau mea hana ʻAmelika e hoʻokau i kā lākou poʻe limahana i ka pilikia.Akā, ua hana ʻia kēia hana ma waho.Akā ʻo kēlā poʻe mea hana outsourcing i kāhea aku e hoʻōki i ka hana keleawe a me ka wili ʻana.
Ma muli o ka liʻiliʻi a me ka liʻiliʻi o nā mea hana keleawe ma ka home a ma waho, e ʻoi aku ka paʻakikī o nā keleawe i ka loaʻa ʻana, e hopena i nā kumukūʻai kūpono ʻole.
No ka hoʻopau paʻa, he liʻiliʻi ka ʻokoʻa ma waena o ke keleawe a me ka zinc.Hāʻawi nā mea ʻelua i nā mea hana paʻa me ka hiki ke haʻi haʻahaʻa kiʻekiʻe, ke kūpaʻa abrasion maikaʻi, a me ka hiki ke hana i nā hopena hopena like.ʻAʻole like nā hemahema o Zinc-he māmā, maʻalahi ke hoʻohana, kūʻē i ka maʻi keleawe, a me ke kumu kūʻai.MARSHALLTOWN hui
Ma ka ʻaoʻao ʻē aʻe, ʻaʻole e lawe ka hana zinc i kēia mau koina like.ʻO kēia kekahi ma muli o ka hoʻomohala ʻana i ka umu hoʻoheheʻe zinc-lead blast i nā makahiki 1960, nāna i hoʻohana i ka hoʻoheheʻe impingement a me ka absorption mahu e hana ai i ka zinc.Ua lawe mai nā hopena i nā pono he nui i nā mea hana a me nā mea kūʻai aku, e like me:
Hoʻohālikelike ʻia ka Zinc me ke keleawe ma nā ʻano āpau.Loaʻa i nā mea ʻelua i ka haʻahaʻa haʻahaʻa kiʻekiʻe a me ke kūpaʻa abrasion maikaʻi, a he mea kūpono ia no ka ʻenekinia paʻa, ʻoiai ʻo ka zinc e piʻi hou aʻe, me ka pale ʻana i ka maʻi keleawe a me kahi ʻaoʻao māmā a maʻalahi e hiki ke hāʻawi i nā ʻaelike me ka hopena like. o.
He wahi liʻiliʻi kēia o ke kumukūʻai o nā mea hana keleawe.Hoʻokumu ʻia ʻo Zinc ma ʻAmelika Hui Pū ʻIa, ʻoi aku ka pololei a ʻaʻole koi i ka wili a me ka deburring, a laila e hōʻemi ana i nā kumukūʻai hana.
ʻAʻole wale kēia e hoʻopakele i kā lākou poʻe limahana mai nā māmā lepo a me nā kūlana olakino koʻikoʻi ʻē aʻe, akā ʻo ia hoʻi, hiki i nā mea hana ke hoʻolilo liʻiliʻi e hana hou aku.A laila e hāʻawi ʻia kēia mau waihona i ka mea ʻaelike e kōkua iā lākou e mālama i ke kumukūʻai o ke kūʻai ʻana i nā mea hana kiʻekiʻe.
Me kēia mau pōmaikaʻi a pau, ʻo ia paha ka manawa no ka ʻoihana e haʻalele i ka makahiki keleawe o nā mea hana paʻa a apo i ka wā e hiki mai ana o ka zinc.
He mea kākau a me ka hoʻoponopono ʻo Megan Rachuy no MARSHALLTOWN, he alakaʻi honua i ka hana ʻana i nā mea hana lima a me nā lako hana no nā ʻoihana like ʻole.Ma ke ʻano he mea kākau kamaʻāina, kākau ʻo ia i ka DIY a me nā ʻike pili pili no ka blog MARSHALLTOWN DIY Workshop.
