Abstract

<p>We developed “Spanplus FT” as a pitch control agent for the DIP process to achieve production capacity of DIP and quality improvement while using poor quality wastepaper. “Spanplus FT” is special water-soluble polymer having hydrophilic part and hydrophobic part. It has an effect to agglutinate pitch selectively.</p><p>So after dosing “Spanplus FT” in flotation part, pitch is attached on froth and pitch removal efficiency is increase. As a result, pitch volume in DIP pulp is decreased.</p><p>Moreover, “Spanplus FT” has a high selectivity for pitch, so it dose not react to suspended solid matter. It leads the decrease of outflow raw material.</p><p>We applied “Spanplus FT” in flotation of newsprint DIP, pitch removal efficiency increase 10-20 %. And suspended solid matter was not removed. it was able to contribute to reduction of outflow raw material</p>
