Description

мое количество порошка поступает в держатель-перемешиватель 8, который нагреваетс  до температуры, обеспечивающей наилучшие услови  дл  адгезии материала покрыти  на частицах порошка.My amount of powder enters the stirrer holder 8, which is heated to a temperature that provides the best conditions for adhesion of the coating material to the powder particles.

Включают испаритель 3 и одновременно вибропривод 11 мембраны. Частицы порошка совершают хаотическое движение внутри полости мембраны под воздействием приложенных к ней поперечных колебаний, частота и амплитуда которых достаточна дл  ведени  процесса нанесени  покрыти .Include the evaporator 3 and at the same time the vibration actuator 11 of the membrane. The powder particles undergo a random motion inside the cavity of the membrane under the influence of transverse oscillations applied to it, the frequency and amplitude of which is sufficient for conducting the coating process.

После достижени  достаточной толщины покрыти  открывают пробку 12. Под действием вибрации порошок ссыпаетс  во внутренней полости мембраны в лоток, который направл ет порошок в ссыпной бункер 7. Затем пробка 12 опускаетс  в исходное положение, из дозатора 6 в полость мембраны подают новую порцию порошка, и процесс повтор етс . После обработки порошка, наход щегос  в загрузочном бункере 5, камеру 1 вскрывают, загружают новым порошком, затем удал ют покрытый попошок.After a sufficient thickness of the coating is reached, the stopper 12 is opened. Under the action of vibration, the powder is poured in the inner cavity of the membrane into the tray, which directs the powder into the dump bin 7. Then the stopper 12 is lowered to its original position, a new batch of powder is fed into the cavity of the membrane 6, and the process is repeated. After processing the powder in the feed hopper 5, chamber 1 is opened, loaded with a new powder, then the coated powder is removed.

Конструктивное оформление мембраны зависит от ее габаритов и гранулометрического состава порошка; она может быть плоской, с конусной поверхностью, закрепленной упруго по периферии или незакрепленной.The structural design of the membrane depends on its size and particle size distribution of the powder; it can be flat, with a conical surface, fixed elastically around the periphery or loose.
