Phosphate fertilizer feedstock, Faʻaaoga mo le fausiaina
Fosphate fertilizer feedstock, Faʻaaoga mo le fausiaina,
Phophoric acid gaosi oloa, Fa'atauga fa'amea fa'akomepiuta,
Amioga fa'aletino:
1. Suavai manino le lanu, Leai se manogi faʻafefe
2. Melting point 42 ℃; vevela 261 ℃.
3.Miscible ma le vai i soo se fua faatatau
faleoloa:
1. Teu i totonu o se faleteuoloa malulu ma ea.
2. Tausia mai le afi ma le vevela.
3. Ua faʻamaufaʻailogaina le afifi.
4. E tatau ona teuina ese mai mea faigofie (mu) mu, alkalis, ma pauta u'amea malosi, ma aloese mai le teuina fefiloi.
5. O le nofoaga e teu ai e tatau ona faʻapipiʻiina i mea talafeagai e taofiofia ai le leak.

Fa'aaogā:
Fa'ato'aga fa'aoga: mea mata o le phosphate fertilizerand fafaga meaʻai
Alamanuia fa'aoga: vaila'au mata'utia
1. Puipui le uamea mai le pala
2. Fa'afefiloi ma le nitric acid e pei o vaila'au fa'alelei e fa'aleleia ai le pito i luga ole u'amea
3.Material o le phosphatide lea e faʻaaogaina mo le gaosiga o oloa fufulu ma iniseti
4.O le gaosiga o le phosphorus o loʻo i ai mea faʻafefe.
Fa'aoga mea'ai fa'aopoopo: fa'a'a'ai fa'ato'aga, Fa'afefete Nutri-ents, , e pei o le coca-cola.
Fa'aaogāga fa'afoma'i: e maua ai vaila'au o lo'o iai le phos-phorus, pei o le Na 2 Glycerophosphat
1, phosphoric acid o le mea mataʻutia mo le gaosiga o faʻamaʻi phosphate taua (superphosphate, potassium dihydrogen phosphate, ma isi), faʻapea foʻi ma mea mataʻutia mo le gaosiga o meaʻai (calcium dihydrogen phosphate).
2, togafitia le uʻamea uʻamea, faʻatupuina le phosphate film i luga o le uʻamea e puipuia ai le uamea mai le pala.
3, faʻafefiloi ma le nitric acid e avea o se vailaʻau kemisi e faʻaleleia ai le maeʻa o le uʻamea.
4, o le gaosiga o sapalai fufuluina, vailaau e tineia ai manu mea mata phosphate ester.
5, o le gaosiga o phosphorus-e aofia ai mea mata retardant mumu.
6, phosphoric acid o se tasi o meaʻai faaopoopo, i meaʻai e pei o se sui oona, meaʻai fefete, cola o loʻo i ai le phosphoric acid. O le Phosphate ose mea'ai fa'aopoopo taua ma e mafai ona fa'aaogaina e fai ma fa'asusuga fa'asusu.
7, phosphoric acid e mafai ona faʻaaogaina e fai ai vailaʻau o loʻo i ai phosphorus, e pei o le sodium glycerophosphate.
