Description

Technical field:

[0001] The invention relates to the technical field of glass manufacturing, in particular to a method for manufacturing high-strength environment-friendly fireproof glass. Background technique:

[0002] The production of fireproof glass in the prior art is to fill flame retardant material between two pieces of glass or use potassium ions in the chemical raw material potassium salt to replace metal cations in the glass, and then perform physical toughening. The disadvantages of the fire-resistant glass made by the above method are: bubbles, impurities, etc. appear in the filled fire-resistant material, and the glass is heavy and the light transmittance is low; the glass replaced by potassium ions is active and unstable due to the potassium ions in the potassium salt. As environmental conditions change, the phenomenon of surface congestion will change, so the fire resistance of glass is not stable, and the manufacturing process is dangerous and complicated, wh...
