Nano-silica composite fireproof glass is a new type of fireproof glass which is made of inorganic expandable nano-silica fireproof glue and multi-layer glass original sheets through a special process.
advantage:
1. Nano-silicon fire-resistant glass consists of two or more layers of glass sandwiched with one or more layers of nano-silicon fire-resistant glue, and the fire-resistant glue is injected into the empty compartment of the laminated glass, and the special glass that can meet the requirements of the corresponding fire resistance grade is formed by polycondensation optimization and compounding. . This sandwich structure makes the glass and glue closely adhere, thus improving the safety of use, and can effectively prevent the outer glass from breaking and hurting people, without the risk of bursting, and has good heat resistance, heat insulation and weather resistance. , sound insulation and transparency.
2. Nano-silicon fireproof glue is a kind of hard inorganic transparent fireproof crystal after polycondensation optimization, so it has super weather resistance, stability, high transparency, no discoloration, no degumming, perfect light transmittance and light fastness. Excellent properties such as foaming.
3. Nano-silicon fire-resistant glass is a fire-resistant adhesive that gradually foams, expands, and becomes carbonized during high-temperature grilling, forming a protective layer with a very small thermal conductivity and good thermal insulation properties, preventing the flame from spreading to the back fire area and weakening the flame. The heat radiation to the back fire side, so as to protect the integrity of the back fire side glass and articles, and play a role in complete fire prevention.
Features:
1. Block the spread and spread of flames, smoke and heat;
2. Meet the A (EI) level fire protection requirements for fire integrity and fire insulation for 0.5h, 1.00h, 1.50h, 2.00h, 3.00h;
3. It has the incomparable permeability of ordinary glass;
4. It has better sound insulation;
5. Be able to produce products of various sizes according to customer needs;
6. The thickness is generally 10--75mm thick glass, which is used for various fire protection;
7. Most of the product shapes are rectangles, squares, circles, etc.
For single-piece cesium-potassium fireproof glass, the glass must be replaced by ions first, and then fireproof tempered. Generally, the surface stress of tempered glass is required to reach 170-250Mpa. However, the surface stress of the air-cooled tempering process is difficult to reach 250Mpa. At this time, the glass is seriously deformed, and even cracks appear on the surface of the glass, and the glass is easily broken during the tempering process. In order to obtain higher surface stress, high wind pressure should be used for tempering treatment, and the heating temperature of the glass should be higher than the normal heating temperature, and the heating time should be appropriately extended, so as to fully clear the residual stress of the glass, which is conducive to the formation of high-strength tempering Fire resistance of glass.
