STUDY OF INFLUENCE SEPARATE PROCESSING WASTEPAPER POLIIONOGENNYMI POLYMERS ON MECHANICAL PROPERTIES OF PAPER
Abstract
The study of influence of the individual chemical polyionic polymer core group of HVV on deinking properties and physico-mechanical properties of the paper, as they supply to various parts of the mass contained in the work. Unfractionated (n/t) and fractional deinking wastepaper MS-5B – 2 fractions – long fiber (DVF) and short (CRF) were taken for research.
Chemical polyionic (polycationic and polyanionic) HVV for the study were as follows: lock "Ultrafiks P-127" flocculant "polyamine SSK" binders: cationic starch "Dinadin CS 537", "Ultrarez DS 125 the Q" glue AAA "Ultrasayz 200" – production of "SKIF Special Chemicals» Ltd., polyanionic binder Na-CMC and cationic polyacrylamide (PAA Cat) – other manufacturers.
A 4 series of experiments were conducted at mass processing. In the experiments the total mass was divided in half and each part is handled differently HVV complex. The following results: the addition of chemicals to the DWF adds strength to the larger share of the existing strength of the paper; increase over separate Ratios respect to VVM (without chemicals) – breaking length, stiffness, tensile, burst resistance, resistance to planar compression (12,7 bar and 15,0 mm), respectively, 34, 24, 47, 57 and 55%; addition of chemicals to increase strength WFC paper samples almost to the strength of the paper DVF; increase over separate Ratios relative to DWF – breaking length, stiffness, tensile, burst resistance, resistance to planar compression (12,7 bar and 15,0 mm), respectively, 25, 41 47, 45 and 48%; chemical additive to the WFC brings its strength properties to the DWF properties; comparing experimental results of physical and mechanical properties of paper, weighing 125 g/m2, with the standards GOST R 53206-2008 on fluting, it can be stated that the method of separate application poliionogennymi weight polymers, especially in combination DVF and CRF, provides a paper grade B-2 on all indicators, paper B-1 in terms of "resistance plane compression" and paper B-0 in terms of "bursting".Downloads
