Fa'aoga
1. Commonly faʻaaogaina suʻesuʻega reagents, faʻaaogaina lautele mo le faʻagata poʻo le acidification.Soli fa'asa'o e le fa'asuavaia, tapenaga o vaifofo pa'u, fa'aolaola.O le gaosiga o pigments, vailaʻau, filo acetate, acetyl compounds, ma isi. E faʻaaogaina foi e faʻaumatia ai le phosphorus, sulfur, hydrohalic acid, ma isi. I le avea ai o se sui oona, e mafai ona faʻaaogaina e fai ma faʻamaʻi faʻafefiloi, saunia vineka, meaʻai apa, jelly. ma sisi, ma faʻaaoga i le aofaʻi talafeagai e tusa ai ma manaʻoga gaosiga.E mafai foi ona faʻaaogaina e avea o se mea e faʻaleleia ai le tofo mo le koji ava, ma o le aofaʻi o loʻo faʻaaogaina o le 0.1-0.3g/kg.Faʻaaogaina e avea o se solvent i le gaosiga o paʻu, palasitika, vali, ma isi. E faʻaaogaina foi e avea o se mea mataʻutia mo le gaosiga o le vinyl acetate, cellulose acetate, menthyl acetate, vailaʻau faʻataʻitaʻi, vailaʻau faʻamaʻi, vailaau faʻamaʻi ma isi faʻasologa o meaola.
2. Commonly fa'aaogaina su'esu'ega reagents.Soli fa'asuavai lautele ma vaisu titration solvents.Faʻaaogaina i le gaosiga o le acetate, cellulose acetate, vailaʻau, pigments, esters, plastics, mea manogi, ma isi.
3.PH tau fa'atonuga.E mafai ona faʻaaogaina mo le saunia o le ethyl acetate, le saunia o filo, vali, faʻapipiʻi, copolymer resins, ma isi, le sauniuniga o le acetic anhydride, chloroacetic acid, glycolic acid ma le pikiina o fale gaosi oloa.
4.E mafai ona faʻaaogaina mo le pikiina o pisinisi.Mo le saunia o alava, faʻapipiʻi, faʻapipiʻi, copolymer resins, ma isi.
5.O se mea taua vailaʻau faʻamaʻi mataʻutia, lea e mafai ona maua ai le tele o vailaʻau vailaʻau.O loʻo faʻaaogaina le falemaʻi vailaʻau e saunia ai vailaʻau eseese, o loʻo faʻaaogaina le vali e gaosia ai le tele o vali, ma o loʻo faʻaaogaina le gaosiga o mea faʻapipiʻi e faʻapipiʻi ai le tele o mea polymer, o se vailaʻau taua tele.E le gata i lea, o loʻo faʻaaogaina foi e fai ma mea faʻapipiʻi fale gaosi oloa, paʻu paʻu paʻu, paʻu latex coagulants, fesoasoani vali, mea manogi faʻapitoa, vailaʻau faʻamaʻi, ma isi, ma faʻaaogaina foi e pei o acidulants, faʻaleleia meaʻai, ma isi.
6.Acetic acid e mafai ona faʻaaogaina i nisi o vaifofo pikiina ma faʻamalo, i vaifofo vaivai vaivai e pei o paʻu (e pei o le galvanizing, electroless nickel plating), i le semi-bright nickel plateing electrolyte e pei o faʻaopoopoga, i le zinc, cadmium passivation solution e mafai ona faʻaleleia le pipii. o le ata passivation, ma e masani ona faʻaaogaina e fetuunai ai le pH o vaifofo faʻapipiʻi vaivai vaivai, e mafai foi ona faʻaaogaina e avea o se solvent mo nisi mea faʻapipiʻi (e pei o le coumarin).
7. Commonly faʻaaogaina suʻesuʻega faʻataʻitaʻiga, solvents lautele ma non-aqueous titration solvents, organic synthesis, synthesis of pigments and pharmaceuticals.
8. Faʻaaogaina i le gaosiga o le acetate, cellulose acetate, vailaʻau, pigments, esters, plastics, mea manogi, ma isi.
