Urea Ammonium Nitrate (UAN)
whakaahuatanga1
Ngā Painga Matua:
✓ 100% tongi hauota wai – Ka hono pai ki ngā pūnaha whakamakuku katoa (te maturuturu, te tauhiuhi, te hurihanga).
✓ Te wairewatanga kua arotauhia – Mā te hanganga kore toenga ka ārai i te aukati i ngā taputapu whakatō.
✓ Te kukū N ngāwari – Kōwhiria te 28%, 30%, 32% rānei kia ōrite ki ngā wāhanga tipu o te hua me ngā āhuatanga o te oneone.
✓ Te whai huatanga o te tukunga-rua – Te hauota nitrate tere te mahi (urupare 24 hāora) + te hauota ammonia/amide tukunga-tonu.
Ngā Kaupapa Hangarau:
● Hototahi ki te NPK – Ka taea te whakaranu ki ngā maniua whākawa/pāhare pākawa mō ngā kaupapa matūkai kua whakaritea.
● He iti te piki me te heke – Mā te hanganga matū pumau ka whakaitihia te ngaronga hauota mā te mimiti.
● Whakamahia mō ngā wā katoa – Ka mahi tonu ahakoa ngā rerekētanga pāmahana (5°C ki te 40°C).
He mea tino pai mō ngā pāmu nui e rapu ana i tētahi pūtake hauota wairewa-wai maha ngā whakamahinga, he tika te tuku me te iti o te utu mahi.

He aha i whiriwhiri ai a Henan Yongchang mō te Urea Ammonium Nitrate Solution (UAN)
1. Ngā Pūtake Hauota Takitoru me te Hanga Pūtaiao
● Kei roto te hauota pākawa, te hauota ammonia, me te hauota amida hei whakarato i te tere me te tukunga pumau, kia tutuki tika ai ngā hiahia matūkai o te hua puta noa i ngā wāhanga tipu katoa.
● Ka whakanui ake i te whai huatanga o te tongi tae atu ki te 30%.
● Mā te wai ka taea te whakamahi pai ki ngā pūnaha wai, ki ngā pūnaha whakamakuku rānei (te maturuturu, te tauhiuhi, te rehu iti), ka taea ai te ahuwhenua tika me te whakaiti i ngā utu mahi.
2. Tākai Ngāwari mō ngā Ratonga Ao
● Ngā Tāke IBC: He pai mō ngā ota iti ki te rahi, ā, he pai hoki mō te kawe/te rokiroki haumaru.
● Ngā tāke ngāwari: Ka whakaiti i te utu mō te takai, ā, he pai hoki mō te taiao.
● Waka Papatipu: He otinga utu-pai mō te hoko nui.
3. Te Whakaputa Tauine me te Tukunga Pono
● Te kaha ā-tau: 100,000 tāne mita.
● Te tere o te whakatutuki i ngā ota ritenga hei whakaiti i ngā mōrearea tuku.
4. Kounga me te Pūmautanga kua Whakamanahia
● Hanganga kua whakamanahia e te ISO.
● Kore he toenga, he tino pumau, ā, he āhuatanga ārai-whakatioata.
5. Ngā Painga mō te Taiao
● Mā te kore puehu ka whakaitihia te parahanga o te hau.
● Ka whakaitihia e te whakamomona tika ngā tūponotanga o te tote o te oneone.
6. Te Whai Hua o te Utu
● Ka whakakore i ngā utu whakarewa tuarua ki ngā maniua totoka.
● Ka whakaiti i te para mā te whakamahi i te mea kua tohua.
7. Ngā Hanganga Whakarite
● E toru ngā kukū (28%, 30%, 32%) i whakaritea mō ngā whakaritenga hauota motuhake o ngā hua.
