mamaacetic acid, o lona uiga, anhydrous acetic acid, acetic acid o se tasi o mea taua faʻalaʻau, mea faʻapipiʻi. E fa'amausali i le aisa i le maualalo o le vevela ma e masani ona ta'uaacetic acid. O le tulaga malulu e 16.6° C (62° F), ma a maeʻa ona faʻamalosia, e avea ma tioata e leai se lanu. O lona vaifofo vai e vaivai le suka ma sili ona pala, ma e malosi tele i metala. O le ausa e iai sona aafiaga ita i mata ma isu. O lea la, o le a le faʻaoga faʻapitoa o acetic acidi pisinisi eseese?
Muamua, fa'aoga fa'apisinisi acetic acid
1. Fa'aaogā mo vali fa'asusu ma vaitusi.
2. I totonu o le gaosiga o meaʻai, e faʻaaogaina e pei o le faʻatonuina o le acidity, acidifier, pickling agent, faʻaleleia le tofo, mea manogi ma isi. O se vailaʻau faʻamaʻi lelei foi, e mafua ona o lona mafai ona faʻaitiitia le pH i lalo ole pH e manaʻomia mo le tuputupu aʻe lelei o microbial.
3. E faʻaaogaina i le paʻu ma palasitika alamanuia. E faʻaaogaina e avea o se solvent ma mea amata mo le tele o polymers taua (e pei o le PVA, PET, ma isi) i totonu o le paʻu ma le palasitika pisinisi.
4. Fa'aaogaina e fai ma mea amata mo vali ma mea fa'apipi'i.
5. Aisa acetic glacial e iai foʻi se sao taua tele i le tagamea, aemaise lava i le puipuia o le leiloa o lanu i luga o lavalava, e malosi le aveeseina o stains, ma e mafai ona faʻaitiitia le pH, o lea.acetic acid e sili ona lauiloa i tagamea. A faʻaaogaina, e manaʻomia le faʻaaogaina e tusa ai ma nisi o faʻatonuga, ma e le mafai ona faʻaoga tauasoacetic acid.
Tulaga lua,acetic acid fa'aoga vaila'au
1. Mo le tuufaatasia o le cellulose acetate. O le cellulose acetate e faʻaaogaina i ata tifaga ma ie. A'o le'i faia le ata o le cellulose acetate, sa masani ona fai ata mai nitrates ma e tele atugaluga mo le saogalemu.
2. Faʻaaogaina e fai ma solu mo le faʻapipiʻiina o le terephthalic acid. P-xylene ua fa'ama'iina i le terephthalic acid. Terephthalic acid o loʻo faʻaaogaina i le tuʻufaʻatasia o le PET ma faʻaaogaina lautele i le gaosiga o fagu palasitika.
3. Fa'aaoga lautele e fa'atupu esters e ala i le tali atu i 'ava malosi eseese. Acetate derivatives e masani ona faʻaaogaina e fai ma meaʻai.
4. Faʻaaogaina mo le tuʻufaʻatasia o le vinyl acetate monomer. O le monomer e mafai ona polymerized e fausia ai le poly (vinyl acetate), lea e masani ona lauiloa o le PVA.
5. Fa'aaogaina e fai ma solvent i le tele o fa'agaio'iga fa'aola.
6. Fa'aaogaina e fai ma fua ma aveese 'ele. O afeaacetic acide tali atu i le vai, e mou atu le fua ma puaa, malepe i lalo mai le malo i se vai e faigofie ona aveese.
