Study on the grinding time duration impact on the properties of paper from alterna from alternative raw materials

Аннотация

Both raw and recycled fiber materials are used for paper production. The increase in percentage use of the latter is due to their paper-forming properties, availability and low cost. The article explores the possibility of using pulp from the inner layer of mulberry twig bark. Mulberry twigs, after removing leaves, which are the main raw material in silk production, have no practical industrial application. Recycling waste - mulberry branches - f o r the production o f pulp is therefore relevant as it is aimed at solving raw material and environmental problems. The purpose of this work is to use local raw materials for paper production, study the impact of processing method of the grinding process on paper forming properties. During grinding the mechanical processes o f changes o f fib ers determine mainly structure o f a paper sheet, and colloidal-physical processes - bind and ability of fibers to form strong, homogenous and smooth structure o f paper.
