        Characteristics of performance: the company's compound belong to the composite grouting glass which is composed of two layers of glass and intermediate sandwich fireproof glue compound and into, has A class A fire glass, insulating refractory integrity stays good insulating fire stays, high transparency, under the same thickness is higher than other similar products fire longer, transparency, under the same fire time, the thickness of the thinner; Thickness is 15 mm, 18 mm, 19 mm, 20 mm, 23 mm, 25 mm and 26 mm, 32 mm, 36 mm, 42 mm, 50 mm, etc; Fireproof heat insulation time: 30 minutes, 45 minutes, 60 minutes, 72 minutes, 90 minutes, 120 minutes, 180 minutes, etc. Our composite fire glass has a national standard, British standard BS476 series.
       Principle: fireproof heat insulation composite insulating fire stays because of composite glass by the fire side of the glass in fire crack, under the influence of intermediate sandwich fireproof glue connect to maintain integrity and keep the whole glass itself when heated foaming flame retardancy of heat-resistant, form a shield effect, heat preservation is not only to prevent the spread of flame, also ensure the back fire glass not to heat up, to prevent the surrounding flammable spontaneous combustion. As shown in figure:
      Figure 1: when it is heated, foam fire glass after partial figure:

 

 

Figure 2: after heated, there is still a foam fire glass partial figure:

 

 

Figure 3: look through observation test furnace mouth fire glass surface by fire fire plastic fire resistance


      


 

The test of compound glass process is as follows:
