Abstract

El projecte es basa en la realització del depilat oxidant amb pell de boví però utilitzant com a reactor una cubeta d’ultrasons en comptes del bombo. Els depilats oxidants que es realitzen són el depilat amb recuperació de pèl i el depilat a pèl desfet. També es realitza una prova de depilat reductor, a bombo, per tal de poder tenir una comparativa entre el mètode tradicional de les adoberies i el mètode aplicat en aquest projecte. Es duen a terme diferents proves inicials, de les quals s’extreu la metodologia adequada per aplicar a les proves finals. En aquestes proves finals es realitzen uns assajos físics i químics, on es conclou que les propietats físiques i químiques són similars, de manera que el depilat oxidant a ultrasons seria viable per tal de comercialitzar-lo.


The project is based on performing oxidative unhairing with bovine hide but using as a reactor an ultrasonic tank instead of a rotating drum. In this project, the oxidative unhairing processes has been carried out with hair that was previously recovered and also with dissolved hair. Besides, a reductive unhairing with rotating drum test was performed in order to have a comparison between the traditional method of tanneries and the method applied in this project. Different tests were carried out in the beginning to determine the best methodology to be applied to the final tests. In these final tests, physical and chemical test were performed. The final results show that the physical and chemical properties are similar. This means that oxidative unhairing with ultrasounds may be viable for commercialization.
