Mea'ai Vasega po'o Alamanuia vasega: O le a le fa'aogaina o le phosphoric acid? Va'ai i manatu nei e ono ona e malamalama ai lea,
Phosphoric acid, PHOSPHORIC ACID gaosi oloa, phosphoric acid e tuʻuina atu, faʻaaogaina o le phosphoric acid,
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
I totonu o le vailaʻau vailaʻau, o le phosphoric acid o se mea taua tele, ae o le mea moni, o le phosphoric acid o se manaʻoga tele e malamalama ai i le eseesega! Mo se faʻataʻitaʻiga, o le a le eseʻesega i le va o meaʻai ma meaʻai vasega phosphoric acid i le faʻaogaina?
O mea o loʻo i totonu o meaʻai ma fale gaosi oloa phosphoric acid e oʻo atu i le 85% ma le 75%. Alamanuia grade phosphoric acid e tele lava ina faaaogaina i le alamanuia kemikolo, e aofia ai lomitusi ie, gaosiga fufuluina, refractories laupapa, metallurgy ma isi alamanuia uamea; E mafai ona fa'aoga le phosphoric acid i mea'ai e tofo ai mea'ai i aso uma e pei o mea'ai susu, fa'ainu uaina, suka ma le suāu'u kuka.
O a fa'aoga autu ole mea'ai phosphoric acid?
1. E mafai ona faʻaaogaina e avea o se meaʻai faʻaopoopo, e pei o le citric malic acid ma isi vailaʻau tofo oona, ma e faʻatino lana matafaioi o se mea mataʻutia mo le fefete ma le phosphate i le kuka.
2. O ē fiafia i uaina e lē o se mea fou i le phosphoric acid! Pe a fa'afefeteina, o le phosphoric acid e mafai ona maua ai se sapalai tumau o meaʻai i le fefete, lea e taofia ai le tuputupu aʻe o siama taʻavale; I le faagasologa o le faia o pia, e mafai foi ona faia se sao lelei o le lactic acid e fetuunai ai le tau o le PH!
3. O punaoa vai ua matua taua nei, ma o le phosphoric acid e mafai foi ona faʻaaogaina e avea o se vaega o mea mataʻutia o fua faʻamamaina mea faʻamama ma vai faʻamaluluina, maua ai i tatou le vai mama sili atu.
Ole vaila'au phosphoric acid e sili atu ona faigata, ae sili atu ona fa'aoga lautele:
1. Phosphoric acid e tatau ona i ai se nofoaga i totonu o fale gaosimea. Afai e te manaʻo e fai le uʻamea o le gaosiga ma faʻaoga sili atu le lamolemole ma matagofie, o le phosphoric acid e tatau ona taua. Pe a faʻafesoʻotaʻi ma le uʻamea, e mafai ona fesoasoani i luga o le vai e le mafai ona faʻaaogaina le phosphate film, e oʻo lava i le galuega mulimuli ane, e faʻaitiitia ai le ono mafai ona pala.
2. O le fa'amamāina gafatia ole phosphoric acid e moni lava le amanaiaina e le tele o tagata. I totonu o le fale lomitusi, e mafai ona faʻaaogaina i totonu o le vai faʻamamaina e fesoasoani e aveese stains i luga o le offset plate sili atu ona atoatoa, ma e mafai foi ona avea ma se vaega o mea faʻapipiʻi faʻapipiʻi i totonu o pisinisi kemisi i aso uma!
3. E le gata i lea, o loʻo i ai foi lona lava nofoaga i le faʻaleleia atili o le ola tautua o le ogaumu, electrolytes maa ma e oʻo lava i le faʻaaogaina masani o oloa tausiga o le paʻu ma mea teuteu.
