Since the batch production of monolithic fireproof glass in China, fireproof glass has been more widely used, but there are several points that must be paid attention to when using:

1. Before selecting fire-proof glass, it is necessary to know the specific fire-fighting requirements of fire-proof components composed of fire-proof glass, whether they are fire prevention, heat insulation or smoke separation, fire resistance limit requirements, etc.

2. Single piece and composite pouring fireproof glass cannot be cut with a glass knife like ordinary flat glass, and must be processed to a fixed length, but the composite (dry process) fireproof glass can meet the cutting requirements.

3. When selecting fireproof glass to form fireproof components, in addition to considering the fireproof durability of glass, its supporting structure and elements must also meet the needs of fire resistance. Single piece cesium potassium fireproof glass is ion exchanged at high temperature for more than 20 hours through special chemical treatment to replace the metal sodium on the glass surface to form low expansion silicate glass. The expansion coefficient is 1.8 * 10-6 / 0f (3.24 * 10-6 / k), so it has efficient heat resistance. At the same time, after physical treatment, high compressive stress is formed on the glass surface, The impact strength is greatly improved. When the glass is broken, it presents a state of small particles, reducing the damage to the human body! The strength of single cesium potassium fireproof glass is 6-12 times that of ordinary glass and 1.5-3 times that of tempered glass! China's building code requires that all products installed on the cut-off with fire protection requirements shall be sampled by the provincial fire brigade where the enterprise is located and sent to the national designated fire protection material testing center (i.e. any one of the national fire protection building material quality supervision and inspection centers in Sichuan and Tianjin) for testing, which must meet the specification requirements, And obtain the inspection report issued by these institutions before sales! The fire resistance test of single piece cesium potassium fireproof glass is carried out according to the current national standards, and the test meets the product specification of the national standard of the people's Republic of China GB15763.1-2001 safety glass and fireproof glass for building.

The advantage of monolithic cesium potassium fireproof glass is that it has little to do with the working temperature, but it has the ability to withstand the impact of heat wave and the rapid change of grace, which depends on the specific heat capacity of the glass (which can affect the rate of temperature rise), thermal conductivity (the rate and distribution of heat passing through the glass) and thermal expansion rate, At the same time, single piece cesium potassium fireproof glass can withstand quenching treatment from 300 ℃ to cold water! The thermal conductivity of single cesium potassium fireproof glass is: 1.13w/m ℃. The thermal expansion rate of single cesium potassium fireproof glass is: 3 * 10-6 / ℃. The water resistance conforms to iso719-hgb and iso720-hga standards. The acid resistance conforms to iso1776 standards. The alkali resistance conforms to iso695-a standards. Compared with traditional grouting fireproof glass, single cesium potassium fireproof glass has high strength and easy installation, The biggest feature is high weather resistance! In addition to bubbles in the production process, the chemical grouting fireproof glass quickly turns milky white under the action of ultraviolet radiation and flame, losing the basic function of glass permeability, so it is impossible to observe the fire situation! Single piece cesium potassium fireproof glass remains transparent under the action of ultraviolet and flame without any change!
