Example Embodiment
[0018] Example 1:
[0019] This embodiment provides a base glaze suitable for rapid firing of glazed tiles, including a base glaze, and the base glaze includes the following components by mass percentage: potassium feldspar 32%, albite 14% , sintered talc 2.5%, medium temperature frit 3.9%, high expansion frit 1.1%, quartz 25%, kaolin 12%, calcined alumina 9.5%. Among them, the SiO in the medium temperature frit is calculated by mass percentage 2 The content is 60~75%, Al 2 O 3 The content is 2 to 10%.
[0020] Further, auxiliary materials can also be added to the above-mentioned bottom glaze to improve the performance of the glaze slurry, and the auxiliary materials include zirconium silicate, sodium carboxymethyl cellulose and sodium tripolyphosphate, wherein, the addition amount of zirconium silicate is the above-mentioned bottom glaze. 10% of the quality of the glaze is used to improve the whiteness of the base glaze. The amount of sodium carboxymethyl cellulose added ...
