Huahana molecular structure:
ʻO Calcium carbide (molecular formula: CaC2), he ʻano mea waiwai nui i hana ʻia mai ka hana kemika o ka limestone. Ma 1892, H. Maysan (French) a me H. Wilson (United state) i ka manawa like i kūkulu i ka calcium carbide production approach ma muli o ka umu ho'ēmi. Ua hoʻokō maikaʻi ʻo ʻAmelika Hui Pū ʻIa i ka hana ʻoihana ma 1895. ʻO ka waiwai o ka calcium carbide e pili ana i kona maʻemaʻe. ʻO kāna huahana ʻoihana ka hapa nui o ka hui ʻana o ka calcium carbide a me ka calcium oxide, a loaʻa pū kekahi me ka sulfur, phosphorus, nitrogen a me nā mea haumia ʻē aʻe. Me ka hoʻonui ʻana o nā mea haumia, ʻike ʻia ke kala hina hina, ʻeleʻele a ʻeleʻele. ʻO ka helu heheʻe a me ka conductivity uila e emi iho me ka emi ʻana o ka maʻemaʻe. ʻO ka maʻemaʻe o kāna huahana ʻoihana he 80% me ka mp he 1800 ~ 2000 °C. Ma ka lumi wela, ʻaʻole ia e pane me ka ea, akā hiki ke loaʻa ka hopena oxidation ma luna o 350 ℃, a loaʻa ka hopena me ka nitrogen ma 600 ~ 700 ℃ e hoʻoulu i ka cyanamide calcium. ʻO ka calcium carbide, i ka wā e hele mai ai me ka wai a i ʻole ka mahu, e hoʻopuka i ka acetylene a hoʻokuʻu i ka nui o ka hoʻomehana. CaC2 + 2H2O─ → C2H2 + Ca (OH) 2 + 125185.32J, 1kg o ka calcium carbide maʻemaʻe hiki ke hana i 366 L o acetylene 366l (15 ℃, 0.1MPa). No laila, no ka mālama ʻana: pono e mālama pono ʻia ka calcium carbide mai ka wai. Hoʻokomo pinepine ʻia i loko o kahi pahu hao i hoʻopaʻa ʻia, a i kekahi manawa mālama ʻia i loko o kahi hale kūʻai maloʻo e hoʻopiha ʻia me ka nitrogen inā pono.
He ʻala like ko ka calcium carbide (CaC2) me ka wai e hana ai i ke kinoea acetylene me ka calcium hydroxide a me ka wela. I ka wā ma mua, ua hoʻohana ʻia ia i nā kukui miners e hana mau i kahi lapalapa acetylene liʻiliʻi e hāʻawi i ka mālamalama i nā mine lanahu.
Hoʻohana ʻia ka calcium carbide ma ke ʻano he desulfurizer, dehydrant o ke kila, wahie i ka hana kila, deoxidizer ikaika a me ke kumu o ke kinoea acetylene. Hoʻohana ʻia ia i mea hoʻomaka no ka hoʻomākaukau ʻana i ka calcium cyanamide, ethylene, chloroprene rubber, acetic acid, dicyandiamide a me cyanide acetate. Hoʻohana ʻia ia i nā kukui carbide, nā pūkuniahi mea pāʻani e like me ka pu-nui a me nā pūkuniahi ʻohe. Hoʻopili ʻia me ka calcium phosphide a hoʻohana ʻia i ka lana ʻana, ka hōʻailona naval hoʻā ʻana iā ia iho ʻo Calcium carbide ka carbide kūpono loa i ka ʻoihana ma muli o kāna kuleana koʻikoʻi ma ke kumu o ka ʻoihana acetylene. Ma na wahi i nele i ka aila, Calcium Carbidehoʻohana ʻia e like me ka mea hoʻomaka no ka hana ʻana i ka acetylene (1 kg o ka carbide yield ~300 liters acetylene), ʻo ia hoʻi, hiki ke hoʻohana ʻia ma ke ʻano he hale kūkulu hale no nā ʻano kemika kūlohelohe (e like me ka vinyl acetate, acetaldehyde a me ka acetic acid. ). I kekahi mau wahi, hoʻohana ʻia ka acetylene e hana i ka vinyl chloride, ka mea maka no ka hana ʻana o PVC.
ʻO kahi hoʻohana liʻiliʻi o ka Calcium Carbide pili i ka ʻoihana ferilizers. Hoʻopili ia me ka nitrogen e hana i ka cyanamide calcium, ʻo ia ka mea hoʻomaka no ka hana ʻana o ka cyanamide (CH2N2). ʻO Cyanamide kahi huahana mahiʻai maʻamau i hoʻohana ʻia e hoʻoulu i ka foliation mua.
Hiki ke hoʻohana ʻia ʻo Calcium Carbide ma ke ʻano he desulfurizing agent no ka hana ʻana i ke kila kalapona haʻahaʻa-sulfur. Hoʻohana ʻia ʻo ia ma ke ʻano he mea hoʻohaʻahaʻa e hana i nā metala mai ko lākou mau paʻakai, e laʻa, no ka hoʻemi pololei ʻana o ke keleawe sulfide i ke keleawe metala. nā lapalapa. Eia kekahi, pili ia i ka hoʻemi ʻana o ke keleawe sulfide i ke keleawe keleawe.
Hiki iā Chemwin ke hāʻawi i ka nui o nā hydrocarbons nui a me nā mea hoʻoheheʻe kemika no nā mea kūʻai aku ʻoihana.Ma mua o kēlā, e heluhelu i ka ʻike kumu e pili ana i ka hana ʻana me mākou:
1. Palekana
ʻO ka palekana kā mākou mea nui. Ma waho aʻe o ka hāʻawi ʻana i nā mea kūʻai aku i ka ʻike e pili ana i ka hoʻohana palekana a me ka hoʻohana ʻana i ka nohona o kā mākou huahana, ua paʻa pū mākou i ka hōʻoia ʻana e hōʻemi ʻia nā pilikia palekana o nā limahana a me nā mea hana ʻaelike i kahi liʻiliʻi kūpono a hiki. No laila, koi mākou i ka mea kūʻai aku e hōʻoia i ka hoʻokō ʻana i nā kūlana palekana kūpono no ka wehe ʻana a me ka mālama ʻana ma mua o kā mākou hoʻouna ʻana (e ʻoluʻolu e nānā i ka appendix HSSE ma nā ʻōlelo a me nā kūlana kūʻai ma lalo). Hiki i kā mākou mau loea HSSE ke hāʻawi i ke alakaʻi i kēia mau kūlana.
2. Keʻano hoʻouna
Hiki i nā mea kūʻai ke kauoha a hāʻawi i nā huahana mai chemwin, a i ʻole hiki iā lākou ke loaʻa nā huahana mai kā mākou hale hana. ʻO nā ʻano kaʻa kaʻa i loaʻa ke kaʻa kaʻa, kaʻaahi a i ʻole ka halihali multimodal (e pili ana nā kūlana kaʻawale).
I ka hihia o nā koi o ka mea kūʻai aku, hiki iā mākou ke kuhikuhi i nā koi o nā moku a i ʻole nā pahu pahu a kau i nā kūlana palekana / loiloi kūikawā a me nā koi.
3. Ka nui kauoha liʻiliʻi
Inā kūʻai ʻoe i nā huahana mai kā mākou pūnaewele, ʻo ka liʻiliʻi liʻiliʻi he 30 tons.
4. Uku
ʻO ke ala uku maʻamau ka unuhi pololei ʻana i loko o 30 mau lā mai ka invoice.
5. Nā palapala hoʻouna
Hāʻawi ʻia kēia mau palapala i kēlā me kēia hoʻouna:
· Bill of Lading, CMR Waybill a i ʻole nā palapala halihali e pili ana
· Palapala hōʻoia o ka nānā ʻana a i ʻole Conformity (inā koi ʻia)
· Nā palapala pili i ka HSSE e like me nā lula
· Nā palapala dute e like me nā lula (inā pono)
