Embodiment 1
[0011] A lining glaze for wine bottles, which is prepared from the following raw materials in parts by weight: hectorite 29-35, quartz 23-27, silica fume 13-17, glaze ash 13-15, clay 12-15 , Water glass 0.4-0.6.
[0012] Preferably, the content of lithium oxide in the lithium feldspar used is greater than 1.0%. The firing temperature of the glaze is 1270-1300°C.
[0013] After the above-mentioned glaze raw materials are mixed, they are ball milled and sieved to obtain a glaze slurry, which is then applied to the inside of the carcass of the wine bottle. After entering the kiln, it is fired at a high temperature of 1270-1300°C to obtain a uniform and dense glaze.
Embodiment 2
[0015] Disclosed is a liner glaze for wine bottles, which is prepared from the following raw materials in parts by weight: lithium feldspar 32, quartz 25, silica fume 15, glaze ash 14, clay 13.5, and water glass 0.5.
[0016] After the above glaze raw materials are mixed, they are ball milled and sieved to obtain glaze slurry, which is then applied to the inside of the wine bottle and fired at 1290°C after entering the kiln.
[0017] The glazed surface of the wine bottle obtained after firing is smooth and dense, without obvious glaze eye bubbles, with a water absorption rate of 0.4% and a corrosion resistance time of 182 hours (the corrosion resistance test adopts the salt spray test method, and 5% sodium chloride solution is used at 35°C) Spray for 2 hours, then place it in a constant temperature and humidity chamber with a temperature of 40°C and a relative humidity of 80%, and observe the time when the surface appears abnormal).
Embodiment 3
[0019] A lining glaze for wine bottles is prepared from the following raw materials in parts by weight: lithium feldspar 32, quartz 26, silica fume 13, glaze ash 13.5, clay 13, and water glass 0.5.
[0020] After the above glaze raw materials are mixed, they are ball milled and sieved to obtain glaze slurry, which is then applied to the inside of the wine bottle and fired at 1290°C after entering the kiln.
[0021] The glaze surface of the wine bottle obtained after firing is smooth and dense, without obvious glaze eye bubbles, with a water absorption rate of 0.4% and a corrosion resistance time of 174 hours.
