Nā ʻāpana zinche mau mea metala i hoʻolei ʻia mai ka zinc metala mua. Hiki ke waiho ʻia nā mea haumia i ka wā o ka hoʻoheheʻe ʻana, akā ʻo ka zinc metala ka mea nui. ʻO nā mea haumia e like me ke kēpau, cadmium, hao, keleawe, tin a me ka alumini hiki ke hoʻopilikia i nā waiwai mechanical a me ke kūpaʻa kemika o nā ingots zinc.
| Papa | Ka nui o ka zinc | Nā mea haumia nui | Nā Hoʻohana Nui |
|---|---|---|---|
| Helu 0 Zinc | ʻAʻole emi ma lalo o 99.995% | Ke kēpau, Cadmium, Keleawe, Hao, Tin | Hana ʻana i nā metala kiʻekiʻe a me nā huahana kumu kūikawā |
| Zinc Helu 1 | ʻAʻole emi ma lalo o 99.99% | Ke kēpau, Cadmium, Keleawe, Hao, Tin | ʻOkika zinc kiʻekiʻe, nā mea hana lāʻau lapaʻau a me nā kemika, electro-galvanizing, nā ʻāpana die-cast |
| ʻO ka zinc helu 2 | ʻAʻole emi ma lalo o 99.95% | Ke kēpau, Cadmium, Keleawe, Hao, Tin | Ka hana ʻana i ka hui zinc, nā pepa zinc pākahiko, nā ʻāpana make-cast |
| Zinc No.3 | ʻAʻole emi ma lalo o 99.90% | Ke kēpau, Cadmium, Keleawe, Hao, Tin | Nā pepa zinc, galvanizing hoʻoluʻu wela, nā mea hao keleawe |
| ʻO ka zinc helu 4 | ʻAʻole emi ma lalo o 99.5% | Kepau, Hao, Cadmium, Keleawe, Arsenic, Antimony, Tin, Aluminum | Nā pepa kinikini, ka pauka kinikini, ka hoʻoheheʻe ʻana i ka wai wela, nā hoʻoheheʻe maʻamau, ka zinc oxide |
Nā noi oʻIʻo zinc
1. Galvanizing: He "Pale Pale" no ke Kila
Loaʻa i ka zinc ke kūpaʻa maikaʻi loa i ka palaho lewa, e lilo ia i mea uhi kūpono no ke kila a me nā ʻāpana kūkulu kila.
Hoʻohana nui ʻia ia i nā ʻoihana kaʻa, kūkulu hale, kūkulu moku a me nā ʻoihana māmā.
2. Ke hana ʻana i nā Alloys Keleawe: Ke kākoʻo nei i nā ʻoihana kaʻa a me nā mīkini
He kuleana koʻikoʻi ko ka zinc i ka hana ʻana i nā kaʻa a me nā mīkini. Hōʻike ka zinc maʻemaʻe i ka ikaika a me ka paʻakikī haʻahaʻa; akā naʻe, ʻo ka hoʻohui ʻana me nā mea e like me ka alumini a me ke keleawe e hoʻomaikaʻi nui i kāna hana mechanical.
3. Nā Alloys Zinc i Hoʻolei ʻia: He "Kōkua Waiwai" no nā ʻĀpana Die-Cast
Hoʻopili nui ʻia nā mea hoʻoheheʻe zinc i hoʻolei ʻia i nā ʻāpana die-cast i hoʻohana nui ʻia i nā ʻoihana kaʻa a me nā ʻoihana māmā. He nui nā mea hoʻoheheʻe zinc i loaʻa ka machinability maikaʻi loa, me ka wikiwiki o ka machining e hiki ana i 60%–80%. Hāʻawi lākou i ka hana stamping maikaʻi e kūpono no ka huki hohonu, a loaʻa iā lākou nā ʻano lubrication ponoʻī e hoʻolōʻihi i ke ola lawelawe die.
Eia kekahi, hiki i nā mea hoʻohui zinc ke hōʻike i ka superplasticity maikaʻi loa ma lalo o nā kūlana kūpono. ʻOiai ʻaʻole magnetic ka zinc, kūpono ia no nā ʻāpana mea kani a me nā hale, a hiki ke hoʻohana ʻia no ka hana ʻana i nā kālā. Eia kekahi, ʻaʻole hana ka zinc i nā huna ahi i ka wā e hoʻopili ai i nā metala ʻē aʻe, kahi e kūpono ai no nā lako pahū ma lalo o ka honua.
4. Hana ʻana i ka Zinc Oxide: He "Kōkua no nā ʻoihana he nui"
ʻO ka hana ʻana o ka zinc oxide kekahi hoʻohana nui ʻana o nā ingots zinc, e helu ana ma kahi o 11% o ka hoʻohana ʻana o ka zinc. Hoʻohana nui ʻia ka zinc oxide i loko o ka ʻoihana rubber, coatings, enamel, pharmaceutical, paʻi a me nā ʻoihana lole, e lawelawe ana i kahi hana koʻikoʻi i ka hoʻomaikaʻi ʻana i ka hana huahana a me ka hōʻoia ʻana i ka maikaʻi.
5. Hana ʻana i ka Pākahiko Kelepona Maloʻo: He "Mea Koʻikoʻi" no ka ʻOihana Pākahiko
Loaʻa i ka zinc nā waiwai kemika kūpono no ka hana ʻana i nā cell maloʻo. Hoʻohana nā cell maloʻo zinc-manganese dioxide i kēia ʻano: hana ka zinc-alloy ma ke ʻano he pahu electrolyte a me ka anode no nā hopena electrochemical i loko o ka pila.
Ma keʻano holoʻokoʻa, ʻaʻole pono ke koho ʻana i ka zinc ingot e hoʻokau wale i ka maʻemaʻe kiʻekiʻe loa. Akā, pono nā mea hoʻohana e kaulike i nā koi hana, nā kūlana huahana a me nā kumukūʻai kūʻai me ka piha.
Manaʻo ʻia ka zinc maʻemaʻe 0# a i ʻole 1# no nā mea hoʻohui kūikawā kiʻekiʻe, electro-galvanizing, nā huahana lāʻau lapaʻau a me nā huahana kemika.
ʻO 2# zinc ke koho makemake ʻia no nā pepa zinc make a me nā pākaukau.
Kūpono nā ʻoaka zinc 3# a me 4# i nā hana galvanizing hot-dip maʻamau a me nā hana hoʻoheheʻe maʻamau.
I ke koho ʻana i nā ʻāpana zinc, ʻaʻole pono ka maʻemaʻe o ka zinc wale nō ke kumu hoʻokahi. ʻO nā pae haumia e like me ke kēpau, ka cadmium a me ka hao e hoʻopilikia pololei i ka maikaʻi o ka huahana i hoʻopau ʻia. E ʻoluʻolu e hoʻohālikelike i nā kumukūʻai maikaʻi a me ke kūʻai ʻana e like me kāu mau kūlana hana kikoʻī.
