Nā kikoʻī huahana
MF: H9N2O4P
MW: 132.06
CAS: 7783-28-0
ʻO 1.Diammonium phosphate, i ʻike ʻia ʻo diammonium hydrogen phosphate (DAP), he mea hoʻohuihui i loko o ka nitrogen a me ka phosphorus.ʻO ka diammonium hydrogen phosphate kahi kiʻekiʻe o ka mea hoʻomomona wikiwiki.Hiki ke ho'ohehe'e 'ia ka Chemicalbook i ka wai a emi mai ka mea pa'a ma hope o ka hemo 'ana.He kūpono ia no nā ʻano mea kanu a me nā lepo, ʻoi aku hoʻi no nā mea kanu makemake i ka nitrogen a pono i ka phosphorus.Hiki ke hoʻohana ʻia e like me ka fertilizer base a i ʻole topdressing, a kūpono ia no ka noi hohonu.
ʻO 2.Diammonium phosphate e pili ana i ka huahana maʻamau, aia ka N18% a me ka p2o548%.He palahalaha a oblique prism ke ano aniani.ʻO ka solubility i ka wai ma 25 ℃ he 71%.ʻO ka pH o kāna hopena saturated hiki i ka 8, ʻoi aku ka kiʻekiʻe ma mua o ka puke kemika monoammonium phosphate.No ka mea he alkaline ka solution saturated o ka diammonium phosphate, hiki ke hoʻemi i ka hoʻopaʻa ʻana o ka hao a me ka aluminika ma ka phosphorus, no laila e hoʻomau ka phosphorus.No laila, paipai ʻia ka diammonium phosphate e hoʻohana i ka lepo acidic.
3.Colorless transparent monoclinic crystal a i ʻole ka pauka keʻokeʻo.Hiki ke hoʻoheheʻe ʻia i ka wai, hiki ʻole ke hoʻoheheʻe i ka waiʻona, acetone a me ka amonia.
4. I kēia manawa,ʻo nāʻano nui o ka hanaʻoihanaʻoihana e pili ana i ka waika phosphoric thermal a me ka hoʻokuʻuʻana i ka phosphoric acid, e hana me ka amonia wai e hana i ka diammonium hydrogen phosphate.ʻO ka mua he maʻemaʻe kiʻekiʻe a he haʻahaʻa ko ka hope.Thermal phosphoric acid neutralization liquid ammonia method dilute the thermal phosphoric acid with distilled water (wai: phosphoric acid = 1.3:1) into dilute phosphoric acid, pump ia i loko o ka pae mua tubular reactor e neutralize me ka amonia, pump the reaction solution into the second ka pae tubular reactor e hana hou aku me ka amonia, i hiki i ka pH waiwai o ka reverse chemicalbook reaction reaction ma kahi o 8.0, hoʻohui i ka arsenic removal agent a me ka mea hoʻoneʻe metala kaumaha e hoʻomaʻemaʻe i ka hopena, kānana, a wehe i nā haumia e like me arsenic a me nā metala kaumaha, Hoʻouna ʻia ka kānana i ka pahu hoʻoponopono maikaʻi e hoʻoponopono i ka waiwai pH i 7.8 ~ 8.0, i hoʻouna ʻia i ka evaporator no ka evaporation a me ka hoʻopaʻa ʻana i ka pili pili o 1.3, hoʻouna ʻia i ka crystallizer hoʻomaha, hoʻoluʻu a crystallized, centrifuged e hoʻokaʻawale i ka wai makuahine. , a maloʻo no ka loaʻa ʻana o ka huahana i hoʻopau ʻia o ka diammonium hydrogen phosphate hiki ke ʻai.Kona h3po4+2nh3 → (NH4) 2HPO4 .
Palapala noi
1. Hoʻohana ʻia ʻo ia e like me ka mea hoʻohui meaʻai, ka pale ahi a me ka mea hoʻopau ahi i ka ʻoihana
2.Ma keʻano he analytical reagent a me ka pale, he mea hoʻomaʻamaʻa wai momona kiʻekiʻe i hoʻohana nuiʻia i nā mea kanu, nā huaʻai, ka laiki a me ka palaoa;ʻAi hū, etc.
3. I ka ʻoihana meaʻai, hoʻohana ʻia e like me ka meaʻai bulking agent, ka mea hoʻoponopono palaoa, ka mea hū, a me ka fermentation auxiliary no ka brewing.Hiki ke hoʻohana ʻia ma ke ʻano he pale.
4.Ma keʻano he mea hoʻohui chemicalbook no nā ruminants.
Hoʻohana ʻia ʻo 5.It no ka paʻi ʻana i ka pā, ka lāʻau lapaʻau, ka pale ahi, ka paipu uila a me nā kumu ʻē aʻe.Hoʻohana nui ʻia ka papa fertilizer e like me ke kiʻekiʻe o ka nitrogen a me ka phosphorus compound fertilizer.
6.Industrial grade e hoʻohana i ka impregnate lāʻau a me nā lole e hoʻonui i ko lākou lōʻihi;Hiki ke hoʻohana ʻia e like me ka pauka maloʻo hoʻopau ahi a me ka phosphorus no nā kukui fluorescent;Hoʻohana ʻia ia i ka paʻi ʻana a me ka hana ʻana i ka pā, ka hana ʻana i nā paipu uila, keramika, enamels, a me nā mea ʻē aʻe, a me ka mālama biochemical o ka wai ʻino;Hoʻohana ʻia ka flame retardant ma ke ʻano he mea insulation thermal o ka mīkini ʻenekini rocket i ka ʻoihana koa.
