Ma rosin na-acha ọcha na rosin hydrogenated bụ rosin nke rosin eke agbanweela.
Rosin abụghị otu ngwakọta, kama ọ bụ ngwakọta kemịkal:
Rosin nwere ihe dị ka 80% nke rosin anhydride na rosin acid, ihe dịka 5 ruo 6% nke resin hydrocarbon, ihe dịka 0.5% nke mmanụ na-agbanwe agbanwe na ihe ndị na-elu ilu.
Hydrogenated rosin:
Ebe ọ bụ na rosin dị mfe kristal, na resin hydrocarbon n'ime ihe owuwu ya nwere njikọ abụọ jikọtara ọnụ, ọ nwere mmeghachi omume dị elu, enweghị ike na oxidation dị mfe. Iji meziwanye nguzogide oxidation ya, enwere ike ịkwado rosin hydrogenated site na imeghachi rosin na hydrogen n'okpuru ọnọdụ catalyzed nrụgide.
Rosin ọcha mmiri:
Rosin mmiri na-acha ọcha bụ rosin polyol nwere agba dị oke ọkụ. A na-eme ya site na rosin a nụchara anụcha dị ka ihe bụ isi site na hydrogenation, esterification na stabilization. Ọ nwere uru nke mmiri na-acha ọcha, ezigbo nguzogide ịka nká na ezigbo ndakọrịta na ihe polymer, nke nwere ike izute mkpa pụrụ iche nke ụlọ ọrụ ntanye.
Enwere ike ịhụ na nkwadebe nke mmiri na-acha ọcha rosin kwesịrị ịgafe na nzọụkwụ nke hydrogenation rosin, ma ọ bụghị nanị na nzọụkwụ nke hydrogenation, ọ bụ ezigbo ngwaahịa a nụchara anụcha.
