Description
Известны способы определени плотности бумагп путем взвепшвани образцов, применени радиоактивных элементов и путем определени количества света прошедшего через бумагу в % ко всему упавшему на бумагу свету.Methods are known for determining the density of paper by suspending the samples, using radioactive elements and by determining the amount of light transmitted through the paper in% of the total light falling on the paper.
Онределепие плотности путем взвешивани образцов не позвол ет автоматизировать процесс производства. Применение радиоактивных изотопов требует сложного и дорогого оборудовани (бетта-весомер), а световой способ пе дает точных результатов.Density of density by weighing samples does not automate the production process. The use of radioactive isotopes requires sophisticated and expensive equipment (beta-meter), and the light method does not provide accurate results.
Предложенный способ устран ет эти педостатки путем пропускание через движушеес полотно бумаги инфракрасных лучей с диапазоном длин воли от 0,8 до 2,6 мк. Известно, что коротковолновую область инфракрасного излучени бумага пропускает плохо, а длинноволновую хорошо. Это позвол ет использовать инфракрасные лучи дл определени плотности бумаги, при этом прибор, авт. ев- № 133337 приоритет ог 30 окт бр 1959 Г-, дл определени плотности конструктивно прост, деHjeB , дает достаточную точность результатов при автоматпзироваином производстве бумаги. Лучи излучает лампа,а интенсивность прошедши.к через бумагу лучей измер ют микроамперметром, шкала которого отградуирована в значени х плотности бумаги.The proposed method eliminates these pedostaki by passing infrared rays through a moving sheet of paper with a range of will lengths from 0.8 to 2.6 microns. It is known that the paper transmits a short-wave region of infrared radiation badly, and a long-wavelength one well. This allows the use of infrared rays to determine the density of the paper, while the device, ed. No. 133337 priority, October 30, 1959 G, to determine the density is structurally simple, deHjeB, provides sufficient accuracy of the results in automatic papermaking. The rays are emitted by a lamp, and the intensity of the light passing through the paper is measured by a microammeter, the scale of which is calibrated in terms of the density of paper.

Способ определени плотности бумаги в процессе ее производст,ва, например, на бумагоделательной машине, о т л и ч а юш и и с тем, что, с целью унрощени определени , через движушеес иолотно бумаги пропускают инфракрасные лучи с диапазоном длин волн от 0,8 до 2,6 мк, с: интенсивность лучей измер ют при помощи фотоэлемента, снабженного микроамперметром, шкала кото1)ого отградуирована в значени х плотности бумагиThe method of determining the density of paper during its production, for example, on a paper machine, is so that with the purpose of defusing the definition, infrared rays with a wavelength range of 0, 8 to 2.6 microns, s: the intensity of the rays is measured using a photocell equipped with a microammeter, the scale of which is calibrated in terms of the density of the paper
