Urea Prilled Fertilizer
He ʻala ʻamoni ko Urea a he ʻono paʻakai. Ke kiʻekiʻe ka mahana wela ma mua o kona wahi heheʻe,
ua decomposed i biuret, ammonia a me cyanic acid. 1g hiki ke hoʻoheheʻe ʻia i ka wai 1mL, 10ml 95% ethanol, 1ml 95%
ethanol paila, 20mL anhydrous ethanol, 6ml methanol a me 2mL glycerol. Hiki ke hoʻoheheʻe ʻia i loko o ka hydrochloric concentrated
ʻakika, aneane hiki ʻole ke hoʻoheheʻe ʻia i ka etera a me ka chloroform. ʻO 7.23 ka pH o 10% wai. Hoonaukiuki.

Ureahoʻohana ʻia i ka nānā ʻana no ka antimony a me ka tin. Ka hoʻoholo ʻana o ke kēpau, calcium, keleawe, gallium, phosphorus, iodide a me
nitrate. ʻO ka hoʻoholo ʻana o ke koko urea nitrogen, me ka hopena maʻamau, ka hoʻoholo ʻana o ka serum bilirubin. Kaawale o
hydrocarbons. Nitric oxide a me nitrous acid i hoʻohana ʻia no ka hoʻoheheʻe ʻana i ka naikokene i loko o ka ʻike. E hoʻomākaukau i ka waena. Folin
ala no ka hoʻoholo 'ana i ka uric acid stabilizer, homogeneous precipitation.
Nā Pono Kino: ʻAʻole keʻokeʻo radioactive, kahe manuahi, manuahi ʻole mai nā mea ʻino i uhi ʻia, spherical & ʻaʻahu i ka nui, 100% mālama ʻia me ka caking.
Hoʻohana: Hoʻohana pololei ʻia e like me ka mea momona a i ʻole nā mea maka o ka NP / NPK fertilizer. He kumu ia o ka polywood, Adblue, Plastic, Resin, Pigment, Feed additive a me ka ʻoihana lāʻau lapaʻau.
Pākē: ma ka nui, ma 50kg / 1,000kg ʻeke i ulana ʻia me ka ʻeke ʻeke i loko e like me nā noi a nā mea kūʻai aku.
1. ʻO kekahi o nā pōmaikaʻi nui o ka granular urea ʻo ia kona hoʻoheheʻe kiʻekiʻe i ka wai a me nā ʻano waiʻona like ʻole, e maʻalahi ai ka hoʻohana ʻana a me ka hōʻoia ʻana i ka lawe ʻana i nā meaʻai e nā mea kanu.
2. ʻO kona maʻalahi a me ka launa pū ʻana me nā ʻano noi like ʻole e like me ka hoʻolaha ʻana, ka lole luna a i ʻole ka fertigation ka mea i koho mua ʻia no ka poʻe mahiʻai e ʻimi nei i ka hoʻomaʻamaʻa ʻana i nā hana hoʻokele waiwai.
3.ka haku mele ogranular urea, me kona decomposition i biuret, ammonia a me ka cyanic acid i nā mahana kiʻekiʻe, e hōʻike ana i kona hiki ke hoʻokuʻu ʻia a me nā hopena lōʻihi i ka meaʻai mea kanu. He mea kūpono kēia no ka hoʻolako mau ʻana i nā meaʻai i loko o ka wā ulu, e hōʻemi ana i ka pono o nā noi hou pinepine.
1. Ma ka mahiʻai, pono ka hoʻohana ʻana i nā mea kanu no ka hoʻoulu ʻana i ka ulu olakino maikaʻi a hoʻonui i nā hua hua.
2.ʻO ka urea nui He ammonia ʻokoʻa a me ka ʻono paʻakai a he mea hoʻomomona waiwai nui i ka nitrogen e pāʻani nui i ka hoʻoikaika ʻana i ka ulu ʻana o nā mea kanu. Ke hoʻohana ʻia i ka lepo, e hana ia i kahi kaʻina hydrolysis, e hoʻokuʻu ana i nā ion ammonium i maʻalahi ʻia e nā aʻa mea kanu. Hoʻonui kēia i ka lawe ʻana i ka nitrogen, e hoʻoikaika i ka ulu a me ka ulu ʻana o nā mea kanu.
3. Ma ka mahiʻai, pono ka hoʻohana ʻana i nā mea kanu e hoʻoikaika i ka ulu ʻana o ka mea kanu olakino a hoʻonui i nā hua hua.
