Phapang Pakeng Tsa Rosin le Petroleum Resin

2022-10-26


Ka bobeli rosin e tšoeu ea metsi le rosin ea hydrogenated ke rosin e fetotsoeng ea rosin ea tlhaho.

Rosin ha se motsoako o le mong, empa ke motsoako oa lik'hemik'hale:

Rosin e na le hoo e ka bang 80% ea rosin anhydride le rosin acid, hoo e ka bang 5 ho 6% ea resin hydrocarbon, hoo e ka bang 0.5% ea oli e fetohang le ho latela lintho tse babang.

Rosin ea haedrojene:

Kaha rosin e bonolo ho kristale, 'me resin hydrocarbon ka sebopeho sa eona sa molek'hule e na le li-conjugated double bonds, e na le ts'ebetso e phahameng, e sa tsitsang le oxidation e bonolo. E le ho ntlafatsa khanyetso ea eona ea oxidation, rosin ea hydrogenated e ka lokisoa ka ho sebetsana le rosin le hydrogen tlas'a khatello ea maemo a bakoang ke khatello.

Rosin e tšoeu ea metsi:

Rosin e tšoeu ea metsi ke polyol rosin e nang le 'mala o bobebe haholo. E entsoe ka rosin e hloekisitsoeng e le thepa ea motheo e tala ka hydrogenation, esterification le stabilization. E na le melemo ea bosoeu ba metsi, ho hanyetsa botsofali hantle le ho lumellana hantle le lisebelisoa tsa polymer, tse ka finyellang litlhoko tse khethehileng tsa indasteri ea sekhomaretsi.

Ho ka bonoa hore ho lokisoa ha rosin e tšoeu ea metsi ho hloka ho feta mohato oa hydrogenation rosin, empa ha e felle feela mohatong oa hydrogenation, ke sehlahisoa se hloekisitsoeng se babatsehang.
