Description

<p>In recent years, pitch troubles by sticky materials have been increasing, because decreased in the amount of high quality waste paper due to restrictions on imports of mixed waste paper in China, and increasing in the utilization rate of afforestation trees such as acacia. Pitch trouble is one of the difficult subjects for paper engineers who explore the stable operations and the quality improvements.</p><p>The pitch contained in the raw material is removed to some extent in the pulping process, but residual pitch is brought into the paper making process. The pitch deposits and adheres to each process, and causes deterioration of quality and operability such as web breaks and defects.</p><p>Our company regards pitch control in the pulping process as the most important solution for pitch trouble. In addition, limited and effective pitch control in the papermaking process is thought to lead to improved quality and productivity.</p><p>This report described our companyʼs efforts to improve productivity in household paper mills, especially pitch trouble.</p>
