Technical innovation points of microwave denture sintering furnace: (1) Microwave heating generates heat through the sample itself, and the sample body is the heating material. Compared with traditional resistance heating, the zirconia material as a whole generates heat by itself, and there is no heat source material pollution, which can overcome the problem of pollution caused by the high temperature volatilization of electrothermal materials. (2) Compared with conventional sintering technology, microwave sintered zirconia ceramic materials are superior to conventional sintering in sintering density, Vickers hardness and biaxial bending strength. Microwave sintered zirconia dentures have high grain consistency and compactness.

⑴ Inspection: Check whether the placement of the equipment is level and stable. Whether the power supply voltage is stable within the specified value (220V±20V, 50Hz), the grounding resistance must be <0.4Ω (if it cannot meet the requirements, please ground it separately). Otherwise, it cannot be turned on and run.

1. The workplace must be kept dry and clean. It is forbidden to place various instruments and tools on the equipment, and no unrelated items are allowed to be stacked around the equipment. 2. If the furnace has been shut down for a long time, the fasteners of the furnace body, the electrical condition and the stainless steel wire mesh shielding strip should be checked before starting the furnace again, and the furnace can be started only after confirming that it is normal.

The top column of the main monitoring screen is used to identify the model and name of the device. Immediately below it are the user login button, the user logout button and the current date and time display, and then the three system control buttons of system start, stop and reset are below it. , the control mode selection buttons, automatic process selection, and application related function buttons are arranged below the system control buttons. The three buttons at the bottom of the main monitoring screen are used to enter other interfaces.

The box-type furnace is mainly composed of furnace body, cabinet, heat preservation system, control system, microwave source, thermocouple, etc. (see Figure 1, overall structure diagram and Figure 2 outline diagram). The oven door is embedded in the cabinet and is flush with the cabinet. The top of the furnace is provided with an exhaust window; the rear of the furnace is provided with a microwave source and a microwave power supply; the right part is provided with an electronic control installation board, an electronic control system and a thermometer, and the interior of the furnace contains a thermal insulation molding module.

The INNOV-03M1600B microwave denture oven is an exquisite microwave high temperature heating equipment that integrates the furnace body and electrical control in one cabinet launched by our company. 1 Main use: suitable for firing of ceramic body and trial production of color glaze formula; also suitable for high temperature sintering, synthesis and heat treatment of other inorganic materials in air atmosphere. The furnace is especially suitable for the development of new ceramic materials in ceramic research institutes and ceramic art studios, and the rapid firing of Taoba samples; it is suitable for new product development and raw material inspection of various research structures. Efficient firing of high-quality, small-batch products can be achieved.
