The submarine will become invisible to 99% thanks to rubber-coated shell coated with tiny air bubbles. This technology allows the submarine virtually disappeared from the screen of the device to detect and locate submarines.
However, after a period of use, the rubber will be damaged, peeling. So you need to replace or repair them.
Before coating rubber shell on submarines shell, It need heating to a certain temperature. But Rubber is a very bad heat conductor. Heating it by conventional means is difficult and it takes a long time. Microwaves heat the material in its whole volume and therefore overcome this problem. The temperature can be reached just in fractions of time.
The time to preheat 1.0x1.0x0.05m rubber shell from 20°C to 60°C is 50 minutes. Reaching higher temperatures is possible as well as having a lower input temperature; of course the time has to be prolonged accordingly in such a case.
The device is controlled by time, power and / or temperature. The operator is needed to load the chamber, start the program and unload the chamber when it is finished.
The device is equipped either with a turntable or other applicable method to ensure the required homogeneity is reached.
