Description

<p>In recent papermaking industry, since the trend of cost reduction and environmental protection, chemicals with good performance by small dosage are highly desired.</p><p>As for surface sizing agents, it has become much more difficult to achieve better and stable performance under poor condition, i.e. highly recycled fibers are used, high ash content paper is produced etc.</p><p>Two types of surface sizing agents, which are solution type and emulsion type, are commercially available. Emulsion type products have mainly been developed in industry, because of less foaming trouble.</p><p>We have developed three different types of surface sizing agents, Type A, B, and C. Type A, comprising a special emulsifier, is designed to enhance hydrophobicity and dispersibility, so that it suits two-roll size press machine well. Type B is designed to have anionic substituent groups, in order to perform well in rich cationic system. Furthermore, by introducing permeable components into Type C, it can easily show sizing effect in low-liquid-absorbing system such as a gate-roll coater.</p><p>In this report, more details will be explained.</p>
