Eseesega i le va o Rosin ma Petroleum Resin

2022-10-26


O le rosin pa'epa'e vai ma le rosin fa'asalaina o rosin ua suia o le rosin masani.

O le Rosin e le o se tuufaatasiga e tasi, ae o se vailaʻau faʻafefiloi:

O le Rosin e aofia ai le tusa ma le 80% o le rosin anhydride ma le rosin acid, e uiga i le 5 i le 6% o le resin hydrocarbon, e uiga i le 0.5% o le suauʻu faʻafefe ma suʻesuʻeina mea oona.

Rosin fa'asalaina:

Talu ai o rosin e faigofie ona tioata, ma o le resin hydrocarbon i lona fausaga mole o loʻo i ai faʻatasi faʻalua faʻatasi, e maualuga lona gaioiga, faʻaletonu ma faigofie oxidation. Ina ia faʻaleleia atili le faʻamaʻiina o le faʻamaʻi, e mafai ona saunia le rosin hydrogenated e ala i le taliina o le rosin ma le hydrogen i lalo o le mamafa o tulaga catalyzed.

Vai pa'epa'e rosin:

Vai-pa'epa'e rosin o se polyol rosin ma matua malamalama lanu. E faia mai le rosin fa'amamaina e avea ma mea fa'avae e ala i le hydrogenation, esterification ma le fa'amautuina. O loʻo i ai le lelei o le paʻepaʻe vai, lelei le matua tetee ma le fetaui lelei ma mea polymer, lea e mafai ona fetaui ma manaʻoga faʻapitoa o le faʻapipiʻi alamanuia.

E mafai ona iloa o le sauniuniga o le vai rosin paʻepaʻe e tatau ona alu i le laasaga o le hydrogenation rosin, ae e le gata i le laasaga o le hydrogenation, o se oloa faamamaina lelei.
