Description
Изобретение относитс к методам испытаний клеевых видов бумаг.This invention relates to methods for testing adhesive types of paper.
Известен метод определени стабильности ироклейки бумаги иутем измерени степени ироклейки ее штриховым методом через определенные промежутки времени.A known method for determining the stability of paper gluing paper and by measuring the degree of gluing paper by its dashed method at certain time intervals.
Целью изобретени вл етс сокращение иродолжительиости испытаний.The aim of the invention is to reduce the number and duration of the tests.
Достигаетс это тем, что образцы бумаги подвергают воздействию чистого кислорода.This is achieved in that the paper samples are exposed to pure oxygen.
Предлагаемый метод заключаетс в то.м, что образцы бумаги размером 20x20 см устанавливают в вертикальном положении на металлическую иодставку и помещают в плотио закрывающийс металлический шкаф, соединенный шлангом с кислородным баллоном через редуктор.The proposed method consists in the fact that paper samples of 20x20 cm in size are placed in a vertical position on the metal fitting and placed in a plastic metal cabinet, connected by a hose to an oxygen cylinder through a reducer.
Кислород 1иодают в шкаф через каждые 0,5 час лри посто нном давлении в течение 1 мин. Дл получени сравнимых результатов необходимо поддерживать посто нным общее количество образцов бумаги в шкафу. Допускаетс колебание количества образцов бумаги ±5 шт.Oxygen is brought to the cabinet every 0.5 hour at constant pressure for 1 minute. To obtain comparable results, it is necessary to keep the total number of paper samples in the cabinet constant. Variations in the number of paper samples ± 5 pcs. Are allowed.
Через установленный промежуток времени, например 30 час, провод т определение степени проклейки бумаги штриховым методом. Иа основании полученных данных определ ют зависимость степени ироклейки бумаги от времени воздействи на нее чистого кислорода , котора и характеризует стабильность проклейки бумаги.After a set period of time, for example 30 hours, the degree of sizing of the paper is carried out by the stroke method. Based on the data obtained, the dependence of the degree of paper glueing on the time of exposure to pure oxygen, which characterizes the stability of paper sizing, is determined.
Описываемый метод определени стабильиости проклейки бумаги позвол ет получить конечные результаты через небольшой промежуток времени от 4 до 20 дней, а не через год, как при использовании известного метода.The described method for determining the stability of paper sizing allows to obtain final results in a short period of time from 4 to 20 days, and not in a year, as when using the known method.
Предмет изобретени Subject invention
Метод определени стабильности проклейки бумаги путем измерени степени проклейки ее штриховым методом через определенные промежутки времени, отличающийс тем, что, с целью сокращени продолжительности испытаний, образцы бумаги подвергают воздействию чистого кислорода.The method of determining the stability of paper sizing by measuring the degree of sizing it by the bar method after a certain period of time, characterized in that, in order to reduce the duration of the test, the paper samples are exposed to pure oxygen.
