Abstract

Inventia se refera la o compozitie de hârtie pentru suporturi nutritive biodegradabile, care contin un aditiv, din nitrolignina si uree, introdus într-un amestec fibros, alcatuit din celuloza kraft naturala, fibra celulozica secundara recuperata si turba si la care se adauga rasina poliamid-piloiamin-epiclorhidrina si sulfat de aluminiu. Utilizarea acestui aditiv, în proportie de 5...10%, raportat la materialul fibros, permite obtinerea unei hartii cu rezistenta mai mare în stare uscata, cu continut ridicat de azot si care manifesta capacitate ridicata de stimulare biologica, evidentiata prin teste de germinare.The invention relates to a paper composition for biodegradable nutrient supports containing an additive of nitrolignin and urea, introduced into a fibrous mixture consisting of natural kraft pulp, recovered secondary cellulose fiber and peat and to which polyamide- piloramine-epichlorohydrin and aluminum sulphate. The use of this additive, in the proportion of 5 to 10%, relative to the fibrous material, allows to obtain a paper with a higher dry state resistance, with a high nitrogen content and exhibiting a high biological stimulation capacity, evidenced by germination tests .
