WebMicrowave ovens. Microwave ovens work by using very high levels of a certain frequency of RF radiation (in the microwave spectrum) to heat foods. When food absorbs microwaves, it causes the water molecules in the food to vibrate, which produces heat. Microwaves do not use x-rays or gamma rays, and they do not make food radioactive. WebMicrowave technology was also proposed to devulcanize waste rubber (Fix, 1980; Novotny et al., 1978 ). This process applies the heat very quickly and uniformly on the waste rubber. The method employs the application of a controlled amount of microwave energy to devulcanize a sulfur vulcanized elastomer, containing polar groups or components, to ... shipyard clydebank
