Abstract
Изобретение относитс к целлюлозно-бумажной промьшшенности и позвол ет упростить процесс при одновременном улучшении качества бумаги за счет повышени ее влагопрочности при сохранении капилл рной впитываемос- ти. В целлюлозную массу ввод т модифицированную сульфанилатом натри анионоактивную аминоформальдегидную смолу и квасцы, полученную при этом смесь размальшают и отливают из нее бумажное полотно. 1 табл.The invention relates to the pulp and paper industry and makes it possible to simplify the process while improving the quality of the paper by increasing its water resistance while maintaining the capillary absorption. A sodium sulfonate modified anionic amino formaldehyde resin and alum are introduced into the cellulose pulp, the resulting mixture is ground and the paper web is cast from it. 1 tab.

Изобретение относитс к способу изготовлени впитьшающей бумаги и может быть использовано в целлюлозно-бумажной промьшшенности дл получени бумаги, которую используют в качестве основы при изготовлении слоистых пластиков,а также при изготовлении отделочной пленки дл больше- форматной фанеры.10The invention relates to a method for manufacturing absorbent paper and can be used in pulp and paper industry for producing paper, which is used as a base in the manufacture of laminated plastics, as well as in the manufacture of finishing film for large plywood.
Целью изобретени вл етс упрощение процесса при одновременном улучшении качества .бумаги за счет повышени ее влагопрочности при сохранении капилл рной впитьшаемости. 15The aim of the invention is to simplify the process while at the same time improving the quality of the paper by increasing its water resistance while maintaining capillary permeability. 15
Пример 1. Размол целлюлозы провод т в лабораторном ролле до степени помола 18-20°ШР. Отлив полученной волокнистой массы осуществл ют на листоотливном аппарате Элнет 20 при концентрации суспензии 0,3-0,4%. Сушку полученных образцов бумаги осуществл ют по прин тому дл впитывающей бумаги режиму.Example 1. The grinding of cellulose is carried out in a laboratory roll to the degree of grinding 18-20 ° SH. Ejection of the obtained fibrous mass is carried out on the Elnet-20 sheet-removal apparatus at a suspension concentration of 0.3-0.4%. Drying of the obtained paper samples is carried out according to the regime adopted for the absorbent paper.
Пример 2. Отличаетс от при- 25 мера 1 тем, что в размолотую массу ввод т смолу в количестве 0,5-2% и квасцы 1-4% от веса волокна.Example 2. Differs from example 25 in that in the ground mass is injected resin in an amount of 0.5-2% and alum 1-4% by weight of the fiber.
Пример 3. Отличаетс тем.Example 3. Differs in topic.
Результаты испытани полученных образцов бумаги представлены в таблице .The results of the test paper samples are presented in the table.
Результаты сравнительных испытани образцов бумаги, полученных по известному и предлагаемому способу, свидетельствуют о том, что предлагае мый способ изготовлени впитьшающей бумаги обеспечивает высокую прочность во влажном состо нии без снижени ее капилл рной впитьюаемости.The results of comparative tests of paper samples obtained by the known and proposed method indicate that the proposed method of manufacturing absorbent paper provides high strength in the wet state without reducing its capillary absorbability.
