Kokubili i-rosin emhlophe yamanzi kanye ne-hydrogenated rosin ziyi-rosin eguquliwe ye-rosin yemvelo.
I-Rosin ayiyona inhlanganisela eyodwa, kodwa ingxube yamakhemikhali:
I-rosin iqukethe cishe u-80% we-rosin anhydride ne-rosin acid, cishe u-5 kuya ku-6% we-resin hydrocarbon, cishe u-0.5% wamafutha aguquguqukayo kanye nokulandela izinto ezibabayo.
I-rosin ene-hydrogen:
Njengoba i-rosin kulula ukuyicwebezela, futhi i-resin hydrocarbon esakhiweni sayo samangqamuzana iqukethe izibopho eziphindwe kabili ezihlanganisiwe, inokuphinda isebenze kabusha, ukungazinzi kanye ne-oxidation elula. Ukuze kuthuthukiswe ukumelana kwayo ne-oxidation, i-rosin eyi-hydrogenated ingalungiswa ngokuphendula i-rosin ne-hydrogen ngaphansi kwezimo ze-catalyzed zengcindezi.
Irosin emhlophe yamanzi:
I-rosin emhlophe ngamanzi iyi-polyol rosin enombala okhanyayo kakhulu. Yenziwe nge-rosin ecwengiwe njengesisekelo sempahla eluhlaza ngokusebenzisa i-hydrogenation, i-esterification kanye nokuqiniswa. Inezinzuzo zokumhlophe kwamanzi, ukumelana nokuguga okuhle nokuhambisana okuhle nezinto ze-polymer, ezingahlangabezana nezidingo ezikhethekile zemboni yokunamathela.
Kungabonakala ukuthi ukulungiswa kwe-rosin emhlophe yamanzi kudinga ukuhamba ngesinyathelo se-hydrogenation rosin, kodwa akukhawulelwe esinyathelweni se-hydrogenation, umkhiqizo omuhle kakhulu ohlanjululwe.
