The vacuum Drying Oven is specially designed for drying heat-sensitive, easily decomposed and easily oxidized substances, and can be filled with inert gas inside, especially some items with complex components can also be dried quickly. It is suitable for high-temperature treatment such as non-oxidative drying, defoaming, curing, welding, annealing, etc.
Unlike other air-ring ovens, the vacuum Drying Oven is in a closed state when it works, resulting in a relatively slow temperature change, mainly because, in a vacuum state, the heat transfer method only relies on heat radiation, while heat radiation transfer The longer the distance, the less the temperature transfer. If you want the temperature to be balanced, you need to make the heat of the vacuum Drying Oven continue to slowly radiate to the entire space of the box, and finally gradually become uniform. This process may take 30 minutes The above time to complete, but also according to the actual situation to judge.
How to change the characteristics of the slow temperature transfer of the vacuum Drying Oven? In fact, the door of the oven can be closed first, but the vacuum is not pumped. At this time, although some heat energy leaks out, because there is air inside as a conduction, the heat transfer is faster. It is also more uniform. When the temperature rises to close to the set temperature, close the door and vacuumize. This can not only express the temperature, but also make the drying speed faster.
Although the above-mentioned solution to the slow temperature transfer is proposed, there are many limitations in the solution. For example, the temperature is too high, so the operation will cause danger, so this method cannot be used under the temperature operation; the production is harmful, flammable and explosive. It is also forbidden to use this method when the gas is used; if the material is easily oxidized, this solution is also extremely unsuitable. So the temperature transfer solution needs to be researched and solved slowly.
