Description
кани излишков суспензии обсыпаетс сухим графитовым порошком зернистостью 0,2- 1,5 мм. Блок с нанесенным слоем покрыти устанавливаетс в шкаф, снабл енный приточно-выт жной вентил цией и сушитс при температуре 26-32°С в течение двух-трех часов . Затем операци .повтор етс . После нанесени 8-10 слоев покрыти формирование оболочки заканчиваетс .Cannons of the excess suspension are sprinkled with dry graphite powder with a grain size of 0.2-1.5 mm. The coated layer unit is installed in a cabinet equipped with supply and exhaust ventilation and dried at a temperature of 26-32 ° C for two to three hours. Then the operation is repeated. After the application of 8-10 layers of coating, the shell formation ends.
