[0013] The specific steps of the preparation method for preparing a non-porous glass-ceramic plate from waste beer bottles are as follows:
[0014] (A) Washing, sorting, crushing, grinding and sieving of waste beer bottles to obtain aggregates of different particle sizes.
[0015] (B) Add different proportions of crystal nucleating agents according to the weight percentage to the batch materials with different particle sizes, and add the binder solution for mixing, and mix evenly.
[0016] (C) The mixture is semi-dry pressed.
[0017] (D) The forming blank is dried.
[0018] (E) The dry billet is sintered, crystallized and cooled in a kiln.
[0019] (F) Trimming, smoothing, polishing and inspecting the sintered glass-ceramic plate.
[0020] In the preparation process, 94% of raw materials (crystal nucleating agent+waste broken beer bottles) are added, and the low-temperature binder of the polyvinyl alcohol solution with a solution concentration of 5% (W / W) is 6%.

[0023] Preparation of emerald-colored glass-ceramic plates: the sorted green waste beer bottles are cleaned, crushed, ground and sieved to obtain aggregates with a particle size of 16-300 mesh; choose CaF 2 Industrial pure CaF with content greater than 98% 2 Is crystal nucleating agent; With 95% (weight percent) total material and 5% (weight percent) CaF 2 The crystal nucleating agent is mixed to obtain a mixture 1, and 94% of the mixture 1 is mixed with a 6% polyvinyl alcohol solution having a solution concentration of 5%, and the mixture is evenly mixed to obtain a mixture 2; the mixture 2 is subjected to vibration and semi-dry pressing Forming, the size of the forming sample is 605×605×23mm green body; after the green body is dried at 80°C for 24 hours, it is sent to the kiln and heated to 500°C for 1 hour, and then heated to 800°C for sintering, 800°C After heat preservation for 2 hours, cool down to 750°C for crystallization. After crystallization and heat preservation f...
