EnglishMonolithic non insulated fireproof glass technology
The technology relates to a manufacturing method of a monolithic fireproof glass with high strength and refractory life and an ionic additive. The utility model is characterized in that the ions with low thermal expansion coefficient are implanted into the general float glass in the form of simple substance, and the catalytic reaction is carried out for a short time at high temperature, so that the ions with high thermal expansion coefficient can be separated at high temperature.
Together, the metal salt ions with high activity ability are organically combined with the ions of the original glass, the overall thermal expansion coefficient is changed, and the comprehensive fire resistance function of the flat glass is enhanced. Together, a variety of ions with low thermal expansion coefficient are combined with the original components of the glass at high temperature to form a stable microcrystalline sub group, which not only improves the light transmittance of the glass flat glass, but also improves the service life of fire resistance.
The product appearance stress of the invention is not less than 145mpa, not more than 175Mpa, and the fire-resistant service life is not less than 15 years, which overcomes the shortcomings of high processing cost of general fireproof glass and short fire-resistant life under the effect of ultraviolet for a long time, simple operation, low requirements of process equipment, short response time, generally only 1-2 hours, low cost, and is very suitable for large-scale production. The implanted ions are in the form of simple substance, and the chemical activity reaches high under high temperature, so that the ions with high coefficient of thermal expansion in the glass can be separated. Under the effect of targeted ion chelating agent, the metal salt ions can combine freely and organically with the original ion groups in the glass to form a more stable ion group.
Then change all the functions of the glass, during which the titanium dioxide formed by the reaction has a strong absorption capacity to ultraviolet rays, which can improve the service life of the fire-proof glass for the construction of exterior wall under the long-term sunlight. The thermal expansion coefficient of silver sulfate and lithium aluminum silicon molecular groups is very low, and can remain stable for 8 hours under the high temperature of 920 ℃. Monolithic high-strength fireproof glass additive belongs to the national patented technology product.
