Embodiment Construction
[0020] The present invention will be described in further detail below in conjunction with specific embodiments.
[0021] The process flow is as follows: raw material entering the factory, inspection, batching, melting, water quenching, inspection, ball milling, inspection, drying, milling, inspection, packaging. According to the following mass percentage ingredients: Al 2 o 3 1~16%, SiO 2 50~75%, CaO 0.5~5%, MgO 0~2%, K 2 O 2~9%, Na 2 O 0~2%, ZnO 2~16%, PbO 0~2%, ZrO 2 3~9%, CeO 2 3~10%, B 2 o 3 0.5~8%. The melting temperature is 1550-1600°C. The fineness of the ball-milled glaze slurry is less than 0.3% (remainder of 325 mesh sieve). The glaze slurry must be dried after the ball milling, and the drying temperature is 150-250°C. The milling parameters are as follows: pulverize through a 250-mesh sieve, and the fineness is <0.3% (325 mesh).
[0022] Experiments were carried out according to the parameters in Table 1, and the results showed that the flash glaze...
