O le Polyvinyl alcohol e faʻaaogaina i le tele o taimi i lo tatou olaga. E tele fa'avasegaga ole polyvinyl alcohol ma le tele o fa'aoga ole polyvinyl alcohol. E taua tele lona sao i la tatou gaosiga ma le olaga. O nisi tagata e le o manino lelei e uiga i le faʻaaogaina o le polyvinyl alcohol, o lea, o le a le faʻaogaina o le polyvinyl alcohol? Sei o tatou tilotilo!
O le a le polyvinyl alcohol?
O le Polyvinyl alcohol o se mea fa'aolaola, fua fa'a-kemikolo [C2H4O] N, foliga mai o le pa'epa'e pa'epa'e, fuga po'o le pa'u pa'u malo, leai se tofo. Soluble i le vai (i luga aʻe o le 95 ℃), soluble i le dimethyl sulfoxide, le mafai ona solu i le penisini, kerosene, suauu fualaau faisua, benzene, toluene, dichloroethane, carbon tetrachloride, acetone, ethyl acetate, methanol, ethylene glycol, ma isi.
Lua, o le matafaioi a le polyvinyl alcohol.
Faʻaaogaina mo le gaosiga o le polyvinyl acetal, paipa faʻafefeteina penisini ma vinylon, ie togafitia sui, emulsifier, faʻapipiʻi pepa, faʻapipiʻi, ma isi.
Fa'avasegaina o mea fa'a-kemikolo
E mafai ona vaevaeina meafaitino mata'utia i vaila'au fa'aola ma mea fa'amea fa'ama'i.
Fa'avasegaina o vaila'au fa'aola
E mafai ona vaevaeina i alkanes ma a latou mea e maua mai ai, alkenes ma a latou mea e maua mai ai, alkynes ma mea e maua mai ai, quinones, aldehydes, alcohols, ketones, phenols, ethers, anhydride, esters, organic acids, carboxylate, carbohydrates, heterocyclic, nitriles, halogenates, aminoids, ma isi vaega.
Fa'avasegaina o vaila'au fa'aletino
O mea autu autu o oloa vailaʻau inorganic o le sulfur, sodium, phosphorus, potassium, calcium ma isi minerale vailaʻau (silasila i alamanuia masima inorganic) ma koale, suauu, kesi masani ma le ea, vai ma isi.
O a mea fa'amea fa'aola kemikolo
Alamanuia vaila'au fa'aola ole fa'apu'upu'u ole alamanuia vaila'au fa'aolaola, fa'aigoa fo'i ole fa'atūlaga fa'aolaola. Faʻavae i luga ole suauʻu, kesi faʻanatura, koale ma isi mea mataʻutia, o le gaosiga autu o le tele o alamanuia faʻatau oloa. Fa'avae vaila'au fa'ama'i fa'aonapo'a tu'usa'o mea e aofia ai le hydrogen, carbon monoxide, methane, ethylene, acetylene, propylene, carbon fa pe sili atu aliphatic hydrocarbons, benzene, toluene, xylene, ethylbenzene ma isi. Mai le suauu mama, suau'u distillate po o le maualalo carbon alkane ta'e kasa, faamamaina kesi ma kesi, pe a uma le vavaeeseina togafitiga, e mafai ona faia mo faamoemoega eseese o aliphatic hydrocarbon mea mata; E mafai ona tu'u'ese'ese mea manogi mai le penisini toe fuata'i o le toe fa'afouga catalytic, le penisini ta'e o le ta'e o le hydrocarbon ma le ta koale o le toe fa'afo'i mai o le koale.
