Ke kumu

I ko mākou ʻāina, ua ʻike ʻia ka calcium ma ke ʻano metala, i hoʻi mai i kekahi o nā hana koʻikoʻi i kōkua ʻia e ka Soviet Union i ko mākou ʻāina ma mua o 1958, kahi ʻoihana ʻoihana koa ma Baotou. Hoʻopili i ke ʻano cathode wai (electrolysis) laina hana calcium metala. I ka makahiki 1961, ua hana ʻia kahi hoʻāʻo liʻiliʻi i ka calcium metala kūpono.

Hoʻomohala:

Hoʻokumu ʻia i ka hopena o 1980s a hiki i ka 1990s mua, me ka hoʻoponopono hoʻolālā ʻana o ka ʻāina i nā ʻoihana ʻoihana koa a me ka manaʻo o ke kulekele "military-to-civil", ua hoʻomaka ka calcium metala e komo i ka mākeke kīwila. I ka makahiki 2003, e like me ka hoʻonui ʻia ʻana o ke koi o ka mākeke no ka calcium metala, ua lilo ʻo Baotou City i kumu waiwai nui o ka calcium metala o ka ʻāina, kahi nona nā laina hana calcium electrolytic ʻehā, me ka mana hana makahiki o 5,000 tons o ka calcium metala a me nā huahana.

ʻO ka puka ʻana o ka calcium Aluminum Alloy:

Ma muli o ke kiʻekiʻe o ka helu heheʻe o ka calcium metala (851 ° C), ʻo ka pau ʻana o ke ahi calcium i ke kaʻina hana o ka hoʻohui ʻana i ka calcium metala i loko o ka wai kepau i hoʻoheheʻe ʻia he kiʻekiʻe ma kahi o 10%, e alakaʻi i nā kumukūʻai kiʻekiʻe. hoʻohana ikehu manawa. No laila, pono e hana i kahi huila me ke alumini metala a me ka calcium metala e hoʻoheheʻe mālie i ka papa ma ka papa. ʻO ka hiʻohiʻona o ka calcium alumini alumini e kuhikuhi pono ana i ka hoʻoponopono ʻana i kēia hemahema i ke kaʻina hoʻomākaukau o ke alakaʻi calcium alumini alumini.

ʻO ka hana ʻana o ka calcium alumini alumini he kaʻina o ka hoʻoheheʻe ʻana a me ka hoʻohui ʻana i kahi mokuʻāina me ka hoʻohana ʻana i ka wela kiʻekiʻe e like me kahi ratio o ka calcium metala a me ka alumini metala.

ʻO ka hoʻokaʻawale ʻana o ka calcium Aluminum Alloy:

Hoʻokaʻawale ʻia ka alumini alumini calcium 70-75% calcium, 25-30% alumini; 80-85% calcium, 15-20% alumini; a me 70-75% calcium 25-30%. Hiki ke hoʻopilikino ʻia e like me ke koi. Loaʻa i ka alumini alumini calcium ka luster metala, ke ʻano ola, a maʻalahi ka pauka maikaʻi e puhi i ka lewa. Hoʻohana nui ʻia ʻo ia ma ke ʻano he master alloy, hoʻomaʻemaʻe a hoʻohaʻahaʻa i ka mea hoʻoheheʻe metala. Hāʻawi ʻia nā huahana ma ke ʻano o nā poloka kūlohelohe, a hiki ke hana ʻia i nā huahana o nā ʻāpana like ʻole e like me nā pono o ka mea hoʻohana.


ʻO ka hoʻokaʻawale maikaʻi ʻana o

Ma ke ʻano he haku kila, ʻoi loa ka koʻikoʻi o nā koi no ka calcium alumini alumini. (1) Hiki ke loli ka maʻiʻo o ka calcium metala ma kahi liʻiliʻi; (2) ʻAʻole pono e hoʻokaʻawale ʻia ka huila; (3) Pono e mālama ʻia nā mea haumia ʻino i loko o kahi ākea kūpono; (4) ʻAʻole pono e hoʻoheheʻe ʻia ma luna o ka ʻili o ka alloy; I ka manawa like, koi ʻia ka hana ʻana, ka hoʻopili ʻana, ka lawe ʻana a me ka mālama ʻana i ka alumini alumini calcium. A ʻo ka poʻe hana o ka calcium-aluminum alloys a mākou e hoʻolako ai, pono e loaʻa iā lākou nā hōʻailona maʻamau.


Ka lawe ʻana a me ka mālama ʻana

ʻO nā waiwai kemika o ka alumini alumini calcium he ikaika loa. He mea maʻalahi ka oxidize a me ke ahi maʻalahi ke ʻike ʻia i ke ahi, ka wai a me ka hopena koʻikoʻi.

1. Packaging

Ma hope o ka ʻoki ʻia ʻana o ka alumini alumini calcium e like me kekahi kikoʻī, hoʻokomo ʻia i loko o kahi ʻeke plastik, kaupaona ʻia, hoʻopiha ʻia me ke kinoea argon, hoʻopaʻa ʻia i ka wela, a laila hoʻokomo ʻia i loko o kahi pahu hao (pahu maʻamau honua). ʻO ka pahu hao he wai wai maikaʻi, hoʻokaʻawale i ka ea a me nā hana anti-impact.

2. Hoʻouka a hoʻouka

I ka wā o ka hoʻouka ʻana a me ka wehe ʻana, pono e hoʻohana ʻia ka forklift a i ʻole crane (electric hoist) no ka hoʻouka ʻana a me ka wehe ʻana. ʻAʻole pono e ʻōwili ʻia a hoʻolei ʻia nā pahu hao i mea e pale ai i ka pōʻino o ka ʻeke pahu a me ka nalowale o ka pale. Hiki i nā kūlana koʻikoʻi ke kumu i ke ahi o ka alumini alumini calcium i loko o ka pahu.

3. Lawelawe

I ka wā o ka lawe ʻana, e nānā i ka pale ʻana i ke ahi, ka pale wai a me ka pale ʻana i ka hopena.

4. Waihona

ʻO ke ola o ka calcium alumini alumini he 3 mau mahina me ka wehe ʻole ʻana i ka pahu. ʻAʻole pono e mālama ʻia ka alumini calcium ma kahi ākea, a pono e mālama ʻia i loko o kahi hale kūʻai maloʻo a me ka ua. Ma hope o ka wehe ʻana i ka ʻeke ʻeke, pono e hoʻohana ʻia e like me ka hiki. Inā ʻaʻole hiki ke hoʻohana ʻia ka huila i ka manawa, pono e pau ka ea i loko o ka ʻeke ʻeke. E nakinaki pono i ka waha me ke kaula, a e hookomo hou iloko o ka pahu hao. Sila i mea e pale aku ai i ka oxidation alloy.

5. ʻAʻole loa e ʻoki ʻia ka pāpaʻi calcium-aluminum i loko o nā pahu hao a i ʻole nā ​​ʻeke pahu i loaʻa ka calcium-aluminum alloy e pale aku i ke ahi. Pono e hana ʻia ka ʻoki ʻana i ka alumini alumini calcium ma ka pā alumini.
