ʻO ka Urea, i kapa ʻia ʻo urea a i ʻole carbamide, loaʻa ke ʻano kemika CH4N2O a i ʻole CO (NH2) 2. He pūhui mea ola i haku ʻia me ka carbon, nitrogen, oxygen, a me ka hydrogen, a he aniani keʻokeʻo. ʻO kekahi o nā pūhui organik maʻalahi ʻo ia ka huahana hope loa i loaʻa i ka nitrogen o ka metabolism protein a me ka decomposition i nā mammals a me kekahi mau iʻa. Ma ke ʻano he fertilizer kūʻokoʻa, kūpono ka urea no nā ʻāina like ʻole a me nā mea kanu. He maʻalahi ka mālama ʻana, maʻalahi ka hoʻohana ʻana, a he liʻiliʻi ka hopena luku ma ka lepo. He mea hoʻomomona kemika ia me ka nui o ka hoʻohana ʻana a me ka maʻiʻo nitrogen kiʻekiʻe loa. Hoʻopili ʻia ka Urea ma lalo o kekahi mau kūlana me ka hoʻohana ʻana i ka ammonia a me carbon dioxide i ka ʻoihana.
Hiki i ka Urea ke hana me nā waikawa e hana i nā paʻakai. Loaʻa iā ia ka hydrolysis. Ma nā wela kiʻekiʻe, hiki ke hoʻokō ʻia nā hopena condensation e hana i ka biuret, triuret, a me ka waikawa cyanuric. E wela i ka 160 ℃ no ka decomposition, e hana ana i ke kinoea ammonia a hoʻololi iā ia i isocyanate. No ka mea aia kēia mea i loko o ka mimi kanaka, ua kapa ʻia ʻo urea. Loaʻa i ka Urea he 46% nitrogen (N), ʻo ia ka mea kiʻekiʻe loa ma waena o nā mea kanu nitrogen paʻa.
Hiki i ka Urea ke hydrolyze e hana i ka amonia a me ke kalapona kalapona ma lalo o ka hana o nā waikawa, nā kumu, a me nā enzymes (pono nā ʻakika a me nā kumu i ka wela).
No ka paʻa ʻole o ka wela, ʻo ka hoʻomehana ʻana i 150-160 ℃ e deamination i ka biuret. Hoʻopili ke keleawe sulfate me ka biuret i ke kala poni a hiki ke hoʻohana ʻia e ʻike i ka urea. Inā hoʻomehana wikiwiki ʻia, e deammonized a trimeric e hana i ʻeono lālā cyclic compound, cyanuric acid.
Hiki ke hana ʻia ka Acetylurea a me ka diacetylurea ma ka hana ʻana me ka acetyl chloride a i ʻole acetic anhydride.
Ma lalo o ka hana o ka sodium ethanol, hoʻololi ia me diethyl malonate e hana i ka malonylurea (ʻike pū ʻia ʻo barbituric acid, ma muli o kona ʻakika).
Ma lalo o ka hana a ka alkaline catalysts e like me ka ammonia, hiki iā ia ke hana me ka formaldehyde a condense i loko o ka resin formaldehyde urea.
E hana me ka hydrazine hydrate e hana i ka aminourea.

1. Inā mālama pono ʻole ʻia ka urea, maʻalahi ke komo ʻana i ka makū a me ka puʻupuʻu, e pili ana i ka maikaʻi kumu o ka urea a hoʻolilo i kekahi mau poho waiwai i ka poʻe mahiʻai. Pono kēia i nā mahiʻai e mālama pono i ka urea. Ma mua o ka hoʻohana ʻana, pono e mālama pono i ka ʻeke urea. I ka wā o ka lawe ʻana, pono e mālama ʻia me ka mālama pono, pale ʻia mai ka ua, a mālama ʻia i kahi maloʻo a maikaʻi hoʻi me ka mahana ma lalo o 20 ℃.
2. Inā mālama nui ʻia, pono e hoʻohana ʻia nā poloka lāʻau e hoʻopili ai i ka lalo no kahi o 20 mau kenimika, a ʻoi aku ka nui ma mua o 50 kenimika ma waena o luna a me ka hale e hoʻomaʻamaʻa i ka ea a me ka hoʻoheheʻe ʻana o ka wai. Pono e waiho ʻia kahi ʻāpana ma waena o nā ʻōpala. No ka hoʻomaʻamaʻa i ka nānā ʻana a me ka ea. Inā ʻaʻole hoʻohana ʻia ka urea i wehe ʻia, pono e hoʻopaʻa i ka waha o ka ʻeke i ka manawa kūpono e maʻalahi ai ka hoʻohana ʻana i ka makahiki aʻe.
3. E pale i ka pili ana me ka ili a me na maka.
Fertilizer: 90% o ka urea i hana ʻia i mea hoʻomomona. Hoʻohui ʻia i ka lepo a hāʻawi i ka nitrogen no nā mea kanu. Hoʻohana ʻia ka urea haʻahaʻa (emi ma lalo o 0.03%) ma ke ʻano he foliar fertilizer. Hiki ke hoʻoheheʻe ʻia i ka wai a hoʻopili ʻia i nā lau o nā mea kanu, ʻoi aku ka nui o nā huaʻai a me ka citrus.
Loaʻa ka maikaʻi o ka fertilizer Urea i ka hāʻawi ʻana i nā mea nitrogen kiʻekiʻe, he mea koʻikoʻi ia no ka metabolism o nā mea kanu a pili pono i ka helu o nā kumu a me nā lau e hoʻomoʻi i ka mālamalama no ka photosynthesis. Eia kekahi, aia ka nitrogen i loko o nā huaora a me nā protein, a pili i ka ʻike protein o nā kīʻaha.
Hoʻohana ʻia ka Urea i nā ʻano mea kanu like ʻole. Pono ka fertilization no ka lilo ʻana o ka lepo i ka nui o ka nitrogen ma hope o ka ʻohi ʻana. Hoʻohana ʻia nā ʻāpana Urea i ka lepo, pono e hana maikaʻi a waiwai i ka bacteria. Hiki ke hoʻohana ʻia i ka wā kanu a ma mua paha. A laila, hydrolyzed ka urea a decomposed.
Pono e mālama pono i ka hoʻopili pono ʻana i ka urea i ka lepo. Inā hoʻohana ʻia ma luna o ka ʻili, a inā ʻaʻole i hoʻokomo ʻia i loko o ka lepo ma o ka hoʻohana kūpono ʻana, ka ua, a i ʻole ka hoʻoinu ʻana, e hoʻoheheʻe ʻia ka amonia a he mea nui ka poho. Hōʻike ʻia ka nele o ka nitrogen i nā mea kanu i ka emi ʻana o ka lau a me ka emi ʻana o ka hana photosynthetic.
ʻO ka hoʻomaʻamaʻa lau: He hana kahiko ka hoʻomaʻamaʻa lau, akā ma ka ʻōlelo maʻamau, ʻoi aku ka liʻiliʻi o ka hoʻohana ʻana i nā meaʻai e pili ana i ka lepo, ʻoi aku ka nui o ka nui. Eia naʻe, ke hōʻike nei kekahi mau moʻolelo honua e hiki i ka hoʻohana ʻana i ka urea urea haʻahaʻa ke hōʻemi i ka nui o ka mea kanu i hoʻopili ʻia i ka lepo me ka ʻole e hoʻololi i ka hana, ka nui, a me ka maikaʻi o nā hua. Ua hōʻike ʻia ka noiʻi ʻana ʻoi aku ka maikaʻi o ka pīpī ʻana i nā lau me ka liʻiliʻi o ka urea e like me ka hoʻoulu ʻana i ka lepo. Ma waho aʻe o nā hoʻolālā fertilization maikaʻi, hōʻoia kēia i ka hana o ka hoʻohana ʻana i nā fertilizers i hui pū me nā kemika mahiʻai ʻē aʻe.
Kemika a me ka plastics: Aia ka Urea i loko o nā adhesives, plastics, resins, inks, pharmaceuticals, a me nā mea hoʻopau no nā textiles, pepa, a me nā metala.
Pākuʻi meaʻai holoholona: Hoʻohui ʻia ka Urea i ka hānai pipi a hāʻawi i ka nitrogen, he mea koʻikoʻi ia no ka hoʻokumu ʻana i ka protein.
Hana ʻia ʻo Resin: ʻO ka resin formaldehyde Urea a me nā resins ʻē aʻe he mau noi like ʻole i ka ʻoihana, e like me ka hana ʻana i ka plywood. Hoʻohana ʻia lākou i nā mea hoʻonaninani a me nā pena.
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)
