To produce high-quality fireproof glass, fireproof glass with fire resistance of 1 ~ 3 hours can be achieved. Selecting high-quality original film is the first step to produce high-quality fireproof glass. The original piece of good fireproof glass can be coated or non coated float glass, tempered glass, composite fireproof glass, or single fireproof glass.

1. Carefully select good car grade original sheet (quality float glass), cut according to the engineering requirements, fine grind the edge, and chamfer according to the actual needs;

2. Place the glass to be processed vertically on the glass frame, and spray the fire-proof liquid on the side that needs fire protection. Note that the selected fire-proof spray pot cannot be a metal spray pot, and the fire-proof liquid sprayed from the spray pot can appear uniform fog on the glass surface;

3. After a piece of glass is sprayed, place cork pads at the four corners of the glass to block it, and spray fireproof liquid in sequence;

4. Place the glass that has been sprayed with fireproof liquid in a dry place for 40 minutes to 1.5 hours. In this process, the glass is subject to chemical ion exchange, which belongs to the stage of chemical fireproof treatment, which can reduce the coefficient of expansion of the glass surface;

5. Conduct tempering operation after cleaning, place the fireproof surface upward, increase the wind pressure by 60 ~ 100%, and ensure that the particle size of the tempered glass surface is less than that of the general tempered glass. This process is a physical treatment process, which plays a key role in the overall quality of the fireproof glass. Final printing of general fire protection signs.

Tempered glass and float glass are the materials for producing single piece cesium potassium fireproof glass. Good tempered and float glass has high hardness and transparency. The processed fireproof glass has good color, bright whole body and good quality; The single piece of fireproof glass can also be used as the data of composite fireproof glass. Because the composite fireproof glass requires higher fire resistance rating, the composite pouring fireproof glass with longer fire resistance can be obtained after the data function is integrated through dry or wet processing.
