Quality creates a safety barrier: the secret of the excellence of hollow and fireproof glass

Insulating glass: scientific selection of materials to create an energy-saving core

The innovation of spacers: the traditional aluminum spacers are abandoned, and stainless steel spacers are used as the core of the warm edge technology. Its thermal conductivity is only 14.3W/m・K, which is much lower than the 160W/m・K of aluminum spacers, and with the ultra-thin wall thickness of 0.09mm, the K value of the whole window can be reduced by 0.1~0.2W/m²・K, which significantly improves the thermal insulation performance. The stainless steel material has no chemical reaction with the off-line Low-E glass soft coating, ensuring a sealing life of more than 20 years in the hollow layer.

Sealant persistence: the use of double sealing process, the first butyl glue to isolate water vapor, the second polysulfide glue or silicone glue to strengthen the bonding. According to the special needs of plateau areas, argon can be filled to balance the internal and external air pressure to avoid glass cracking.

Fireproof glass: nanotechnology, reconstructing the logic of fireproofing
Quotation of fireproof adhesive: a house in SuzhouCrystal nano silicone fireproof adhesive, using imported food-grade raw materials, non-toxic and harmless and excellent fire resistance. At a high temperature of 1000°C, the fireproof adhesive quickly foams to form a honeycomb carbonized layer, which controls the temperature of the backfire surface below 140°C, and the fire-resistant duration can reach 1.5 hours, far exceeding the requirements of the national standard GB15763.1.

Quenching of raw glass: low iron content silica sand (iron content <</b30> 0.015%) is used to produce ultra-clear float glass, with light transmittance > 85%. After chemical tempering, the depth of the stress layer is up to 40~90μm, the impact strength is increased by more than 5 times, and the obtuse angle particles are formed after crushing, which meets the GB15763.1-2009 safety standard.

2. Process innovation: define the height of the industry with technological breakthroughs
Insulating glass: intelligent production, precise control
Digital flexible production line: introduced by an original film manufacturerThe AI visual inspection system can achieve 0.01mm-level accuracy recognition of defects such as scratches and bubbles on the glass surface, and the defective product rate is less than 0.3%. The automatic sealing robot is adopted, and the thickness error of the adhesive layer is controlled at ±0.1mm, so as to ensure that the air tightness of the hollow layer reaches the first-class standard of GB/T 11944-2002.

The ultimate pursuit of energy-saving performance: by optimizing the hollow layer structure (e.g6mm Low-E glass + 12A insulating glass + 6mm tempered glass), the heat transfer coefficient K value is as low as 1.2W/(m²・K), which is more than 50% energy-saving compared with ordinary insulating glass. The argon filling process further reduces the thermal conductivity of the hollow layer to 0.024W/(m・K) to meet the energy-saving needs of severe cold areas.

Fireproof glass: the tempering of art and technology
The ingenuity of the grouting process: the inclined pouring technology is adopted, and the fireproof adhesive is filled evenly without bubbles. Bake at 50°C for 2 hours to fully bond the adhesive to the glass, with 180 minutes of fire resistance integrity, and has passed international certifications such as BS EN 1634-1:2008.

Breakthrough in sandwich technology: research and development of double-layer fireproof adhesive composite structure (such as 5mm tempered glass + 1mm fireproof adhesive + 3mm float glass), while maintaining the light transmittance of >75%, the fire resistance limit is increased to 2 hours, which is suitable for fireproof partition walls of high-rise buildings.

3. Quality control: build safety barriers in the whole process
Insulating glass: a multi-dimensional detection system
Air tightness test: Using the pressure decay method, the air leakage rate < 0.05m³/(m・h) under the pressure difference of ±1000Pa, which is 3 times better than the GB/T 11944-2002 standard. </b30>

Energy-saving performance verification: the edge dew point is detected by the thermal imager, and there is no condensation in the environment of -60°C; Tested to ISO 15099 standards, the solar heat gain coefficient SHGC ≤ 0.25, which meets the requirements for LEED Gold certification.

Fireproof glass: Reliable quality from extreme testing
Fire resistance test: simulating a 1000°C fire scene, passing the GB 15763.1-2009 standard test, the average temperature rise of the backfire surface is <140°C, the single-point temperature rise is <180°C, and the flame does not penetrate. </b30>

Impact resistance verification: 1.1kg steel ball is used to impact from a height of 1.5m in free fall, the glass is not broken, and it meets the EN 356 Class 1B1 standard.

Fourth, quality empowerment: value sublimation from the laboratory to the market
Validation of benchmarking projects
Commercial complex application: customized for an international financial center6mm fireproof glass + 12A insulating glass + 6mm Low-E glass, fire integrity 1.5 hours, heat transfer coefficient K=1.1W/(m²・K), China Green Building 3 Star Certification.

Breakthrough in the industrial field: The purification, heat insulation and fireproof insulating glass developed for an electronic clean room integrates fireproof, dustproof and airtight functions, and has passed the national test, with a fire-resistant duration of 1.5 hours and a light transmittance of >85%.

Take quality as the boat, and move forward in the wave of safety and energy saving. From raw materials to finished products, from process to service, every link is engraved with a dedication to excellence. In the future, we will drive quality upgrading with scientific and technological innovation, so that every piece of glass will become an eternal light that protects life and transmits value.
