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
Mea'ai ma alamanuia grade phosphoric acid o ni vaila'au taua e lua e fa'aaogaina lautele i vaega eseese. O a eseesega i le va o latou i le taimi o le faʻaaogaina, ma pe faʻapefea ona e mauaina se nofoaga e sili atu ona talafeagai.
1. Food grade phosphoric acid
Food grade phosphoric acid o se tioata e leai se lanu, manino poʻo sina samasama samasama ma malosi malosi ma mea faʻapipiʻi. E mafai ona tali atu i ion u'amea e gaosia phosphates insoluble, ma o lea e faʻaaogaina lautele i lemeaaialamanuia. Tulaga lelei, e le afaina i le tino o le tagata.
2. Alamanuia vasega phosphoric acid
Alamanuia vasega phosphoric acid e pala ma acidic. O le mama o alamanuia vasega phosphoric acid e fai si maualalo, ae e lelei catalytic gaoioiga ma le mautu, ma e masani ona faaaogaina i fanua e pei o inisinia kemisi, metallurgy, ma vai togafitiga.
I le faagasologa o le faʻaaogaina, o le lautele o le faʻaogaina o le lua e le tutusa foi. Mo se faʻataʻitaʻiga, o meaʻai faʻamaʻi phosphoric acid o se vailaʻau faʻamaʻi masani e mafai ona faʻaleleia ai le gaʻo o meaʻai ma faʻaleleia lona tofo. Mo se fa'ata'ita'iga, o le fa'aopoopoina o se aofa'iga talafeagai o mea'ai phosphoric acid i oloa e pei o meainu, lole, ma mea manogi e mafai ona maua ai se tofo oona uiga ese.
Lona lua, e mafai ona avea o se pa puipui e faatumauina le fou ma le tofo o meaai. O le fa'aopoopoina o mea'ai phosphoric acid i oloa e pei o le yogurt ma le siamu e mafai ona taofia ai le pala o mea'ai. E mafai foi ona tali atu i ions u'amea i mea'ai e fa'atupu ai phosphates e le mafai ona solu, ma fa'aitiitia ai mea o lo'o i totonu o u'amea mamafa i mea'ai.
Alamanuia grade phosphoric acid o loʻo faʻaaogaina lautele i le gaosiga o vailaʻau, e pei o le gaosiga o le phosphatefugala'au, vailaau fa'alafua, vali, ma isi. E le gata i lea, e mafai foi ona faʻaaogaina le phosphoric acid i fale gaosi oloa e avea o se afi mumu, faʻamaʻi faʻamaʻi, catalyst, ma isi.
E faia se sao taua i le fanua metallurgical, e pei o le faaiila, aveesea ele, fufulu acid, ma isi o metals. E le gata i lea, e mafai fo'i ona fa'aogaina le phosphoric acid i fale gaosi oloa e aveese mai ai metala, e pei o le ta'ita'i, apa, ma isi mea mai ma'a otaota. O loʻo i ai le tele o faʻaoga i totonu o le faʻaogaina o vai, lea e mafai ona faʻamalo lelei le faʻamalo, palapala, ma microorganisms i totonu o le vai, ma faʻaleleia le lelei o le vai.
Faatasi ai ma le faʻaauau pea o le faʻalauteleina o le faʻaogaina o fanua o meaʻai ma fale gaosi oloa phosphoric acid, ua faʻateleina le manaʻoga maketi i lea tausaga ma lea tausaga. Ole mana'oga ole maketi mo alamanuia grade phosphoric acid o lo'o i ai se fa'amoemoe lautele, ma o le fa'aleleia atili o mea'ai maloloina, lanu meamata, ma le maualuga o mea'ai ua maua ai fo'i avanoa fou mo le maketi o mea'ai phosphoric acid.
I se aotelega, o mea'ai ma alamanuia grade phosphoric acid o lo'o i ai avanoa lautele mo le fa'aogaina i vaega eseese. Faʻasaga i tua o le faʻateleina o manaʻoga maketi, e manaʻomia e atinaʻe le faʻafouina ma faʻaleleia le lelei e faʻafetaui ai manaʻoga maketi! Afai e manaʻomia, faʻamolemole lagona le saoloto e faʻafesoʻotaʻi ma fesoʻotaʻi.
