cze Výroba a vlastnosti dřevotřísky a papíru z odpadní makové slámy Vzhledem k nedostatku dřeva v některých zemích je nutné jej nahradit jinými surovinami a zároveň využít odpadní materiál. Cílem tohoto výzkumu je využít makovou slámu pro efektivní přeměnu možných lignocelulózových materiálů – buničiny a dřevotřískových desek. Jejich vhodnost pro výrobu kompozitů je posuzována na základě vybraných fyzikálních nebo mechanických vlastností. Sláma z makovic; buničina; dusičnanovo-alkalická buničina; dřevotříska; mechanické vlastnosti
eng Production and properties of particleboard and paper from waste poppy straw Due to the scarcity of wood in some countries, it is necessary to replace it with other raw materials and at the same time use the waste material. The aim of this research is to use poppy waste straw for the efficient conversion of possible lignocellulosic materials - pulps and particleboards. Their suitability for the production of composites is assessed on the basis of selected physical or mechanical properties. Tensile strength index, burst strength index and air permeability by Gurley have been identified as critical properties of pulp made from poppy straw through two delignification methods. The better mechanical properties, i.e., tensile strength index, were achieved at 52.7 N<middle dot>m/g for the sodium pulp, but the nitrate-alkali method also showed corresponding values at 45.9 N<middle dot>m/g. Similar parameters to those of bagasse or similar fast-growing plants were achieved in particleboard production. The results of this research are used to evaluate poppy straw as an alternative raw material to produce biocomposites.
