Urea,ʻikeʻiaʻo urrea or carbamide, he conipical school ch4n24 2.ʻO ia kahi country. ʻO kekahi o nā mea hoʻohui o nā mea hoʻohui maʻalahi loaʻo ia ka mea nui o ka huahana Me he mea certilizer neuteral, he kūpono kūpono no nāʻano like a me nā mea kanu. He mea maʻalahi ke mālama, kūpono e hoʻohana ai, a he hopena liʻiliʻi loa ma ka lepo. He mea kanu lāʻau lapaʻau nitrogen me ka nui o ka hoʻohanaʻana a me nā mea kiʻekiʻe kiʻekiʻe kiʻekiʻe. Ua hoʻohālikelikeʻiaʻo Urea ma lalo o kekahi mau kūlana me ka hoʻohanaʻana i ka Am lāuaʻo Caronbide Dioxide ma kaʻoihana.
Hiki i ka urea ke hana i nā acids e hana i nā salts. He hydollysis. I nā kiʻekiʻe kiʻekiʻe, hiki ke laweʻia nā hopena kuʻuna e hana i ka nui o ka curet, triret, a me ka cyuniric acid acid. Wela i 160 ℃ no ka decomposition, hana i nā gebnia gas a hoʻololi i loko o ka isocynate. No ka mea,ʻo kēia mea kēia o ke kanaka i loko o ka urine kanaka, ua kapaʻiaʻo Urea. Urea i 46% nitrogen (n),ʻo ia ka mea kiʻekiʻe kiʻekiʻe ma waena o nā mea lapaʻau pontrogen.
Hiki iā Urea ke lilo i mea e hana ai i ka ammonia a me ka carbon dioxide ma lalo o ka hana o nā acids, nā kumulāʻau a me nā bardids
No ka hoʻomauʻana o ka thermal, hoʻomehana i ka 150-160 ℃ e deeminina i ka biouret. ʻO ka colper sulfeate i nā mea nui me biret i loko o kahi kalaʻulaʻula a hiki ke hoʻohanaʻia eʻike iā urea. Inā hele wikiwiki, e hanaʻia a hanaʻia a me ka trimeric e hana i kahi hui cyclid cyclid ided.
ʻO Acetylureada a me Diacetylurea hiki ke hoʻokumuʻia e ka hanaʻana me ka nui o ka maʻi acityl
Ma lalo o ka hana o ka sodium ethanol, e hana ana me ka malotate malloyl e hana i ka malonyluceda
Ma lalo o ka hana o nā catalyst alkaline e like me ka ammonia, hiki iā ia ke hana me ka formaldehyde a me ka conderal
Hana hou me ka hydrazine hydrate e hana ai iā Aminoreada.

1. Inā mālama ponoʻiaʻo Urea, he mea maʻalahi ke hoʻopiliʻana i ka wai a me ka clump Pono kēia i nā mea mahiʻai e mālama pono iā Urea. Ma mua o ka hoʻohanaʻana, pono ia e mālama i ka pahu pākeke urea. I ka wā e kaʻawale ana, pono ia e hoʻopaʻaʻia me ka mālama, paleʻia ka mālamaʻana mai ka ua, a mālamaʻia i kahi papa maloʻo ma lalo o 20 ℃.
2. Inā mālamaʻia ia i nā nui nui, pono e hoʻohanaʻia nā poloka lāʻau e pili ana i lalo e pili ana i kahi o nā makahiki he 50 a me ka nui o ka papani. Pono e waihoʻia kahi pauku ma waena o nā pā. E hoʻomaʻamaʻa i ka nānāʻana a me ka hoʻokaʻawaleʻana. Ināʻaʻole i weheʻia ka urea i weheʻia, pono e hōʻailona i ka waha o kaʻeke i ka manawa kūpono e hoʻohana ai i ka manawa aʻe.
3. Hōʻalo i ka hoʻopili me nāʻili a me nā maka.
ʻO Fertilizer:ʻO 90% o ka Urea i hanaʻia e like me ka certilizer. Hoʻohuiʻia i ka lepo a hāʻawi i nā nitrogen no nā mea kanu. Haʻahaʻa haʻahaʻa (emi ma lalo o 0,03%) Urea i hoʻohanaʻia e like me ka forlilizer fertilizer. He mea hoʻohālikelike ia i ka wai a noi i nā lau o nā mea kanu, he momona ka momona a me nā māla.
ʻO Urea Fertilizer ka mea kūpono o ka hāʻawiʻana i nā mea nitrogen kiʻekiʻe,ʻo ia ka mea e pili ana i ka nui o nā lāʻau lapaʻau a me nā lau e pili ana i ka nui o nā kumulāʻau no nā photosynthesis. Eia kekahi,ʻo Nitrogen i kēia manawa ma nā vitamins a me nā protein, a pili pū me kaʻike o ka protein.
Hoʻohanaʻiaʻo Urea i nāʻano likeʻole o nā mea kanu. Pono ka mea hana no ka mea ua nalowale ka lepo nui o ka nitrogen ma hope o ka hōʻiliʻiliʻana. Hoʻohanaʻia nā'āpana Urea ma ka lepo, e pono ai e hana maikaʻi a waiwai i nā baictteria. Hiki ke hanaʻia ka noi i ka wā o ka kanuʻana a iʻole ma mua. A laila, he hydroldhed a ure urea.
Pono e mālamaʻia ka mālamaʻana i ka wā e noi pololei ai iā Urea i ka lepo. Inā hoʻohanaʻia ma luna o kaʻaoʻao, a iʻole e hoʻokomoʻia i loko o ka lepo ma o ka hoʻohana ponoʻana, he mea nui loa a me ka nalo. ʻO ka nele o ka nitrogen i nā mea kanu i hōʻikeʻia ma kahi hōʻemi i kahi o ka lau a me ka emiʻana o ka hana photosynthetic.
ʻO ka hoʻomaʻamaʻaʻana o ka lau:ʻO ka hoʻomaʻamaʻaʻana o ka lau o ka lau, akā e'ōlelo maʻamau,ʻo ka'ōlelo maʻamau,ʻo ka hoʻohanaʻana o nā mea kanu e pili ana i nā nui o nā nui. Eia nō naʻe, hōʻike kekahi mau moʻolelo honua i ka hoʻohanaʻana o ka urea urea hiki i ka nui o ka firtilizer i hoʻohanaʻia i ka lepo, ka nui. Ua hōʻikeʻo ka noiʻiʻana e pili ana i ka foliar e pīpī ana me kahi liʻiliʻi liʻiliʻi o ka urea e like me ka nui o ka slaray. Ma kahi o nā hoʻolālā fetilization kūpono, hōʻoia kēia i ka hana o ka hoʻohanaʻana i nā mea kanu i ka hoʻopiliʻana i nā mea kanu manu.
Nā lāʻau lapaʻau a me nā plastics: urea i kēia manawa i nā adhesives, plastics, nā pale, nā mea hoʻolālā, a hoʻopau i nā mea lapaʻau, a me nā'āpana, a me nā metala.
ʻO nā meaʻai meaʻai holoholona
Resin resin: urea formaldehyde resin a me nā mea'ē aʻe he mau mea'ē aʻe i nā noi likeʻole ma kaʻoihana, e like me ka hana plywood. Hoʻohanaʻia lākou i loko o nā cosmetics a me nā pena.
Hiki i ke ChemWin ke hāʻawi i kahi ākea ākea o nā hydrocarbons a me nā mea kanu lāʻau lapaʻau no nā mea kūʻai aku o nāʻoihanaʻoihana.Ma mua o kēlā, eʻoluʻolu e heluhelu i kaʻike kiko'ī e pili ana i ka hanaʻana me mākou:
1. Palekana
ʻO ka palekana ka mea nui o kā mākou pono. Ma kahi o ka hāʻawiʻana i nā mea kūʻai aku me kaʻike e pili ana i ka hoʻohana palekanaʻana a me ka hoʻohanaʻana i nā mea palekana o kā mākou mau huahana a me nā mea hana palekana. No laila, makemake mākou i ka mea kūʻai aku e hōʻoia i ka laweʻana i nā kūlana palekana a me nā mālama palekana palekana ma mua o ko mākou hāʻawiʻana a me nā kūlana o ka HSSE ma lalo nei). Hiki i kā mākou mau poʻe makemake HSSE e hiki ke hāʻawi alakaʻi i kēia mau kūlana.
2. Ke kaʻina lawe
Hiki i nā mea kūʻai aku ke kauoha a hāʻawi i nā huahana mai ka chemwin, a i hiki iā lākou ke loaʻa nā huahana mai ka mea kanu hana. ʻO nāʻano hana i loaʻa i ka halihali e komo ai i nā kaʻa, rail a iʻole nā mea e hoʻopili ai i nāʻano (paeʻokoʻa).
Ma ka hihia o nā koi o ka mea kūʻai aku, hiki iā mākou ke kuhikuhi i nā koi o nā hale kūʻai a iʻole nā mea hoʻokele a me nā pono palekana a me nā koi.
3.ʻO ka nui o ka heluʻokoʻa
Inā kūʻaiʻoe i nā huahana mai kā mākou pūnaewele,ʻo ka nui o ka helu helu liʻiliʻi he 30 tons.
4.Pay ma
ʻO keʻano uku uku maʻamau ka hoʻokaʻawaleʻana i loko o 30 mau lā mai ka invoice.

Hāʻawiʻia nā palapala e pili ana i kēlā me kēia hāʻawi:
· Bila o ka lading, cmr wiybill a iʻole nā mea lawe kiʻi e pili ana i ka lawe
· Palapala hōʻoia o ka nānāʻana a iʻole ke kūlike (inā pono)
· Nā palapala pili e pili ana i ka laina me nā lula
·ʻO ka palapala palapala ma ka laina me nā lula (inā pono)
