CHEMICAL ASPECTS OF INFLUENCE ГИДРОФИЛЬНЫХ AND WATERPROOF COMPONENTS ON EFFICIENCY OF ABSORBENCY OF THE PAPER
The article the structure and properties of cardboard bases used in the manufacture of cardboard cores. The analysis of the quality of raw materials for the chemical, physical, mechanical and влагопрочностным indicators. We studied the effect of ash on the strength and water absorption of the investigated samples of cardboard. Analyzed the correlation between indicators of cardboard sizing-fundamentals and its absorption capacity. The influence of wet strength and adhesive properties of initial fiber stock on the final product quality was studied. Influence of the initial raw materials on the strength properties of cardboard cores were assessed in terms of their radial strength. The research group developed efficient technological requirements to the quality of initial stock providing the high quality of cardboard cores.
