Iyatọ Laarin Rosin Ati Resini Epo

2022-10-26


Mejeeji rosin funfun omi ati rosin hydrogenated ti wa ni iyipada rosin ti rosin adayeba.

Rosin kii ṣe apopọ ẹyọkan, ṣugbọn idapọ kemikali kan:

Rosin ni nipa 80% rosin anhydride ati rosin acid, nipa 5 si 6% ti resini hydrocarbon, nipa 0.5% ti epo iyipada ati itopase awọn nkan kikoro.

Rosin ti o ni hydrogen:

Niwọn igba ti rosin jẹ rọrun lati ṣe kristalize, ati resini hydrocarbon ninu eto molikula rẹ ni awọn ifunmọ ilọpo meji ti o so pọ, o ni ifaseyin giga, aisedeede ati ifoyina irọrun. Lati le mu ilọsiwaju ifoyina rẹ pọ si, rosin hydrogenated le ṣee mura silẹ nipa didaṣe rosin pẹlu hydrogen labẹ awọn ipo catalyzed titẹ.

Rosin funfun omi:

Rosin omi-funfun jẹ rosin polyol pẹlu awọ ina pupọ. O ṣe lati rosin ti a ti tunṣe bi ohun elo aise ipilẹ nipasẹ hydrogenation, esterification ati imuduro. O ni awọn anfani ti omi funfun funfun, ti ogbo ti ogbo ti o dara ati ibamu ti o dara pẹlu awọn ohun elo polima, eyiti o le pade awọn iwulo pataki ti ile-iṣẹ alemora.

O le rii pe igbaradi ti rosin funfun omi nilo lati lọ nipasẹ igbesẹ ti rosin hydrogenation, ṣugbọn kii ṣe opin si igbesẹ ti hydrogenation, o jẹ ọja ti a tunṣe ti o dara julọ.
