Method of Separating Non-Metallic Material Using Microwave Radiation

摘要

A method of high speed cutting of non-metallic materials ( 14 ), preferably glass and laminated glass, is described. In the inventive method a concentrated microwave radiation ( 1 ) with appropriate frequency and power density is chosen so as to accomplish heating of at least one selected area ( 2 ) of the body at the required separating propagation path ( 3 ) to required temperature in a selected short time while ensuring that this temperature is large enough to create a thermal stress ( 6 ) through the thickness of the selected area that results in the separating of the body material. In one embodiment of the invention a method of high speed cutting laminated glass is described wherein concentrated microwave radiation is used for delaminating adhesive film before the step of separating the glass body.
