Abstract

Способ касается повышения скорости обезвоживания и улучшения удерживания мелочи, который эффективен в не содержащей наполнителя волокнистой массе без диоксида кремния и частиц бентонитного типа и может быть использован в целлюлозно-бумажной промышленности при изготовлении газетной бумаги. В бумажную массу добавляют катионоактивный или амфотерный крахмал, катионоактивный полиэлектролит и высокомолекулярный анионоактивный полиакриламидный сополимер последовательно или в сочетании. Техническим результатом является улучшение условий проведения процесса изготовления бумаги. 6 з.п. ф-лы, 9 табл.
