содержание, соответствующее точке росы люминофорной суспензии, преимущественно равным 60-80 г/кг сухого воздуха, температуру - 110-120° С, а скорость - Л1/С.the content corresponding to the dew point of the phosphor suspension, mostly equal to 60-80 g / kg of dry air, the temperature - 110-120 ° C, and the speed - L1 / C.
Пример. При сущке люминофорных. покрытий люминесцентных ламп мощностью 8Q Вт на. опытной установке ОКТБ ЙТТФ поддерживалась температура теплоносител 100-120° С при влагосодержании 60-80 г/кг сухого воздуха и скорости 6-10 м/с. Температура люминофорной суспензии перед нанесением на внутреннюю поверхность лампы составл ла 20° С.Example. With the presence of phosphor. 8QW fluorescent lamp coatings on. pilot plant OKTB YTTF maintained the temperature of the coolant 100-120 ° C with a moisture content of 60-80 g / kg of dry air and a speed of 6-10 m / s. The temperature of the phosphor suspension before application to the inner surface of the lamp was 20 ° C.
При сопрй косновенки увлажненного теплоносител с поверхностью люмпнофорного покрыти наблюдалась конденсаци влаги (2 2 в расчете на одну лампу), а температура сло повышалась до 40-50° С. Это позволило избежать интенсивного обезвоживани поверхностного сло в период прогрева, когда температура сло , а следовательно , и его влагопроводность не велики .At the end of the moistened heat carrier with the surface of the luminaire coating, moisture condensation was observed (2 2 per lamp), and the layer temperature rose to 40-50 ° C. This allowed us to avoid intensive dehydration of the surface layer during the warm-up period, when the temperature of the layer, and therefore and its moisture permeability is not large.
В дальнейшем по мере выхода на равновесную температуру всего сло и повышени его влагопроводности интенсивна сушка не вызывала бпасных перепадов .влажности по толщине сло . Этому способствовала также конденса1ци влаги в период прогрева, вызывающа црвышение влажности в поверхностном слое.Subsequently, as the entire layer reached the equilibrium temperature and its moisture conductivity increased, intensive drying did not cause dangerous moisture changes in the thickness of the layer. This was also promoted by condensation of moisture during the warm-up period, causing a reddening of moisture in the surface layer.
Использование предлагаемого способа сушки позволит в 2-3 раза интенсифицировать процесс сушки и повысить прочность покрыти .Using the proposed method of drying will allow to intensify the drying process 2-3 times and increase the strength of the coating.
Ожидаемый экономический эффект по отрасли от внедрени всего комплекса работ 2,0-2,5 млн. руб. в год.The expected economic effect on the industry from the introduction of the entire complex of works is 2.0-2.5 million rubles. in year.
