Description
Summary:In this work obtaining of magnesium hydroxide from the solutions obtained during magnesium removal from zinc concentrates is presented. The received product was used for the winning of composites from polyethylene (PE) using extrusion and injection methods. The obtained composites were tested in terms of thermal stability (TG, DTG) as well as combustibility (LOI and thermovision camera). The preliminary results indicate the beneficial effect of the decrease of PE quality by magnesium hydroxide obtained by means of solution purification and precipitation of Mg(OH)2 by means of soda lye.
