Embodiment Construction

[0013] Below by three specific embodiments the present invention is described in detail as follows:

[0014]

[0015] The weakly frosted glaze on the bottom of the dish contains the following components by weight: petalite 70%, potassium feldspar 10%, barium carbonate 4%, zirconium silicate 4%, spodumene 4%, Suzhou soil 5%, zinc oxide 3%.

[0016] The nano-titanium modified film contains the following components by weight: 90% nano-titanium, 5% high-temperature resin, and 5% low-temperature glass powder.

[0017] The specific production steps and process parameters are as follows:

[0018] The surface and bottom glaze raw materials are divided into balls: material: water = 1.5: 1:0.6 for ball milling and crushing to a certain particle size, and then sieved through iron suction and 300-mesh sieve to obtain the super anti-fouling glaze water on the upper surface and the bottom surface of the plate. Weak frosted glaze glaze water.

[0019] All the green body raw materials a...

Abstract

The invention discloses a ceramic bearing platter for a microwave oven and a preparation method of the ceramic bearing platter. A platter body is prepared from a green body by using soapstone and white clay base blanks; the platter surface is coated by super anti-fouling glaze and a nano titanium modified membrane; and the platter bottom is coated by weak frosted glass glaze and then is fired. The preparation method comprises the following steps: carrying out ball-milling and crushing on all base blanks according to the ratio of balls to blanks to water being 1.7 to 1 to 1.2; adding a trace amount of sodium humate to evenly mix; sieving through a 300-mesh sieve, absorbing iron, pressing into mud, pugging in vacuum, and mechanically pressing and molding by a plastic press; pressing into the platter, quickly sintering the blanks at 1290 DEG C for 2 hours; respectively spraying glaze water on the upper surface and the lower surface of the platter; quickly firing the glaze at middle temperature of 1200 DEG C, and then coating the nano titanium modified membrane on the upper surface of the platter; and sintering the nano modified membrane at low temperature of 600 DEG C, so as to prepare the product. Compared with traditional crystallized glass, the ceramic material is easier to mold, and lighter in weight; the platter material is lower in cost, less in energy consumption, better in microwave performance, and more even in heating; and super soil resistance of the platter surface can be achieved through special glaze water in a full enveloping manner.

Description

technical field [0001] The invention relates to microwave dielectric ceramics for microwave ovens, in particular to a ceramic carrying shallow plate for microwave ovens. Background technique [0002] Microwave dielectric ceramics refer to ceramic materials with excellent dielectric properties in the microwave frequency range of 300MHz to 300GHz. The wave transmission is strong and uniform. It has been widely used in industry and military, and is used in modern communications and mobile phones in civilian use. , Microwave oven bearing plate, etc., it is an emerging special ceramic material in China. [0003] At present, there are two types of microwave oven loading boards: the rotary table type and the fixed type. The fixed type can save the power consumption of the rotary table drive motor and the drive motor, reduce the volume of the microwave oven chamber, and reduce the consumption of production materials; The plate can be used to hold food directly, and it can be rotate...
