Method for producing fire-resisting glass and dedicated production equipment

Abstract

This invention discloses method and specific apparatus for producing fireproof glass. The apparatus comprises: an upper stage plate, a furnace, a cooling wind grating and a lower stage plate. A baffle is set between the heating furnace and the cooling wind grating. The method comprises: (1) spray-coating a cesium / potassium salt solution onto glass at normal temperature; (2) naturally wind-drying the spray-coated glass at normal temperature, placing in a 680-725 deg.C tempering furnace, rapidly heating, cooling, circulating the glass between the heating furnace and the cooling wind grating by a roll so that the heating and cooling temperature is uniform, and unloading to obtain fireproof glass. The cesium / potassium salt solution comprises: cesium salt 0.8-1.2%, potassium salt 38-41%, acetone 40-45%, formic acid 8-13%, and Swiss-78 6-8%. The fireproof glass has such advantages as high heat resistance, low specific gravity, high light permeability, no yellowing, and no air bubbles.

Description

Technical field:

[0001] The invention relates to a production method and special production equipment of a single piece of fireproof glass. Background technique:

[0002] Most of the glass in the original civil buildings and industrial buildings is ordinary flat, solid or tempered and insulating glass. The common disadvantages of these glass products are:

[0003] A) Glass surface stress is not high:

[0004] The surface compressive stress of ordinary glass is generally 15-65 MPa, the surface compressive stress of tempered glass is generally 70-180 MPa, and the surface compressive stress of high-temperature fireproof glass is 100-150 MPa higher than that of tempered glass produced by traditional technology;

[0005] B) The thermal shock resistance is not high:

[0006] Due to the thermal radiation of the fire or the flame (high-temperature smoke) directly acting on the glass surface, the glass surface is heated rapidly, and the thermal shock resistance of the glass is impr...
