Abstract

Przedmiotem zgłoszenia jest sposób hemolizy sztywnej biopianki poliuretanowej polegający na tym, że miesza się piankę z czynnikiem hemolizującym, którego istotą jest to, że stosuje się piankę, do której wytworzenia zastosowano wyłącznie biopoliol z oleju roślinnego albo mieszaninę biopoliolu w ilości od 25% do 100% mas. i poliolu petrochemicznego, przy czym piankę wprowadza się partiami do glikolu dietylenowego albo do biopoliolu o liczbie hydroksylowej 327 – 350 mgKOH/g, lepkości 156 - 182 mPa•s i średniej masie cząsteczkowej 337 - 357 g/mol zsyntezowanego w reakcji transestryfikacji oleju rzepakowego trietanoloaminą i reakcję prowadzi się do momentu rozpuszczenia pianki pod ciśnieniem atmosferycznym.The subject of the application is a method of hemolysis of rigid polyurethane biofoam consisting in mixing the foam with a hemolyzing agent, the essence of which is that a foam is used for the production of which only a biopolyol from vegetable oil or a mixture of a biopolyol in an amount of 25% to 100% by weight and a petrochemical polyol was used, wherein the foam is introduced in batches into diethylene glycol or a biopolyol with a hydroxyl number of 327 - 350 mgKOH/g, a viscosity of 156 - 182 mPa•s and an average molecular weight of 337 - 357 g/mol synthesized in the transesterification reaction of rapeseed oil with triethanolamine, and the reaction is carried out until the foam dissolves under atmospheric pressure.
