Example Embodiment
[0021] Example 1: According to the required bottle mouth shape (such as full thread), the corresponding bottle mouth pressure injection steel mold is processed, and the prepared ceramic raw material (sintering temperature is higher than the bottle body 20℃) is processed into fine powder by dry ball milling, and the powder is added With 10wt% paraffin wax, the ceramic raw material fine powder and the paraffin wax are fully mixed in a mixer at about 80°C to obtain the hot-press grouting material. A semi-finished product molded bottle mouth molded body is obtained by a hot pressure grouting method. The semi-finished product is buried in fine alumina powder and the paraffin wax is burned out in a kiln at 800°C to obtain a semi-finished product without paraffin wax, which is then sintered in a kiln at 1190°C.
[0022] The sintered bottle mouth and the dry bottle body formed by grouting are bonded together with a glaze water binder (melting point temperature of 1100℃), and the sintered...
Example Embodiment
[0023] Example 2: Same as Example 1, in which the ceramic wine bottle is a sintered body after grouting, that is, the mouth and body are sintered, bonded and sintered again, the final size of the mouth and the design size deviation +0.08 mm.
