Description
ваетс обща толщина сло а всей площади сетки. В итоге получаетс одиослойное иолотно, имеющее значительно более равномерный иросвет, чем без дополнительного налива. Произведенными на нолупромьинленной мащвне iBHnO Бумлрома выработками бумаги предлагаемым способом установлено, что наиболее эффективным вл етс дополнительный налив со скоростью меньщей , чем скорость сетки, т. е. равной 0,8. Это объ сн етс тем, что при отставании дополнительной струи суспензии от сеткп происходит :носто нное перераспределение ее с толстых мест полотна на тонкие, что и обеспечивает выравнивание толщины бумажного полотна. Концентраци массы в первом напорном щике 0,8%, во втором 0,4%, композици массы В обоих щиках 100% беленой целлюлозы, количество волокна из второго щика 15% общего количества. Просвет бумаги определ етс с помощью прибора ИНП конструкции УкрНИИба . На этом приборе на диаграмме потенциометра записываетс структурна диаграмма бумажного полотна, площадь которой вл етс критерием просвета, причем чем меньще 1площадь, тем лучще просвет бумаги. Результаты испытани бумаги, полученной по предлагаемому способу, в сравнении с бумагой, полученной известными способами, даны в таблице.The total thickness of the entire grid area is. The result is an odiolayer iolotno, which has a much more uniform light than with no additional filling. The paper workings produced by the proposed method produced at the iBHnO Bumlrom's newly-wedged milling machine was found to be the most effective additional filling at a speed lower than the net speed, i.e., 0.8. This is due to the fact that when an additional jet of lag is lagging behind the net, a steady state redistribution from thick places of the web to thin ones occurs, which ensures the alignment of the thickness of the paper web. The mass concentration in the first pressure box is 0.8%, in the second 0.4%, the weight composition in both boxes is 100% bleached pulp, the amount of fiber from the second box is 15% of the total. The lumen of the paper is determined with the help of the device INP design UkrNIIba. In this instrument, a structural diagram of a paper web is recorded on a potentiometer chart, the area of which is a criterion of a lumen, and the smaller the area, the better the lumen of the paper. The results of the test paper obtained by the proposed method, in comparison with paper obtained by known methods, are given in the table.
:В результате реализации данного способа брак уменьщаетс на 1%.: As a result of the implementation of this method, the waste is reduced by 1%.
Ожидаема годова экономи дл одной бумагоделательной мащипы, вырабатывающей газетную бумагу, составит:The expected annual savings for one papermaking machine that produces newsprint paper will be:
