HYBRID TI-CONTAINING LIGNOCELLULOSIC POWDERED MATERIAL FROM RECYCLED CARDBOARD

Abstract

Paper’s and cardboard’s wastes are the most frequent and voluminous type of garbage that requires recycling for preservation of ecosystem. In the work on the example of recycled cardboard, the possibility of processing secondary plant raw materials into new useful hybrid lignocellulosic products of powdered type using the system from tetrachloride titanium and hexane (TiCl4-C6H14) was shown. A comparative analysis of hybrid powdered materials from recycled cardboard and wood pulp obtained under equal conditions was carried out. A proportional increase in the mass and ash content of powdered materials was shown with an increase in the amount mmoles of Ti (IV) in the reaction system. Was found that most of the adsorbed on the fibers surface of titanium compounds are readily soluble in an aqueous 10% solution of sulfuric acid, what indicates the possibility of their simple removal, if necessary. Was shown that fractional distribution along the length of fibers considerably narrows after the treatment, the average length decreases to 7,1 times. Was established that the prevailing fraction of all hybrid destructed samples is represented by fibers with a length of 0,12–0,15 mm, regardless of the consumption of Ti (IV), however, in products from cardboard, fraction of that fibers is higher, average dimensional characteristics are less than in products from wood pulp.
