Zombini i-rosin emhlophe yamanzi kunye ne-hydrogenated rosin ziguquliwe i-rosin yendalo.
I-Rosin ayisiyonto enye, kodwa ngumxube wekhemikhali:
I-rosin iqulethe malunga ne-80% ye-rosin anhydride kunye ne-rosin acid, malunga ne-5 ukuya kwi-6% ye-resin hydrocarbon, malunga ne-0.5% yeoli eguquguqukayo kunye nokulandelela izinto ezikrakra.
Irosin eneHydrojeni:
Ekubeni i-rosin ilula i-crystallize, kwaye i-resin hydrocarbon kwisakhiwo sayo se-molecular iqulethe i-conjugated double bonds, i-reactivity ephezulu, ukungazinzi kunye ne-oxidation elula. Ukuze kuphuculwe ukumelana ne-oxidation, i-rosin ye-hydrogenated inokulungiswa ngokuphendula i-rosin kunye ne-hydrogen phantsi kweemeko ezixinzelelekileyo.
Irosin emhlophe yamanzi:
Irosin emhlophe yamanzi yi-polyol rosin enombala okhanyayo kakhulu. Yenziwe kwi-rosin esulungekileyo njengesiseko sezinto eziluhlaza ngokusebenzisa i-hydrogenation, i-esterification kunye nokuzinzisa. Ineenzuzo zobumhlophe bamanzi, ukuchasana nokuguga okuhle kunye nokuhambelana kakuhle kunye nezixhobo zepolymer, ezinokuhlangabezana neemfuno ezikhethekileyo zeshishini lokunamathela.
Kuyabonakala ukuba ukulungiswa kwamanzi e-rosin emhlophe kufuneka kudlule kwisinyathelo se-hydrogenation rosin, kodwa akukhawulelwanga kwisinyathelo se-hydrogenation, yimveliso egqwesileyo ecocekileyo.
