发明名称 METHOD AND COMPOSITION FOR IMPROVING FIBER QUALITY AND PROCESS EFFICIENCY IN MECHANICAL PULPING
摘要 This invention provides a composition and method for improving a mechanical pulping process by decreasing freeness and amount of shives, providing energy and chemical savings, and enhancing brightness and mechanical strength of a paper product made from a pulp material in the process. The composition includes formulations, such as surfactants, chelants, hydrotropes, reductive and oxidative pulp modifiers, and pH-controlling chemicals. The method includes selectively introducing these formulations to the pulp material in the mechanical pulping process.
