Especially due to the frequent changes of ambient temperature and pressure, the gas in the hollow cavity of the hollow glass is always in a state of thermal expansion or contraction, so that the sealant is in a state of stress for a long time. For the traditional double-channel sealing system, the action of this force will cause the deformation of the sealant and the loss of its function, and the moisture in the environment will continue to penetrate from the edge of the hollow glass into the hollow cavity. At the same time, the effects of ultraviolet rays, water and other corrosive gases in the environment will accelerate the aging of the sealant, thereby accelerating the rate of water vapor entering the hollow cavity and the escape of the filled argon gas. As a result, the water vapor content in the hollow cavity of the hollow glass increases and the seal fails, resulting in a reduction in energy saving effect. Due to the elasticity of the thermoplastic spacer sealing system, the edge stress can be effectively released when the environment changes. At the same time, the thermoplastic spacer has a higher cohesive force to resist changes brought about by the load and ensure the stability of the sealing structure.

The change of sealant under the influence of three-glass two-cavity insulating glass environment

For the three-glass two-cavity insulating glass (as shown in the figure), the glass on both sides of it will be subjected to the action of the other cavity to produce greater stress, which will cause the deformation of the butyl rubber and reduce the effect of the first seal. Increase the passage of water vapor, so that the insulating glass will fail faster, and the sealing advantage of the thermoplastic spacer will be more obvious.

Structural defects. For the pre-formed spacer hollow system, the overflow problem will accompany for life and cannot be avoided, but TPS will completely avoid this problem due to the complete elastic sealing spacer system.

Water vapor sealing test method: The test of each cycle consists of high and low temperature alternating cycles and constant temperature and humidity. The first stage: 56 cycles, every 12 hours is a temperature cycle, the temperature is from -18℃±2℃～53℃±1℃; the second stage: the temperature is 58℃±1℃, relative humidity is greater than 95% environment The temperature is maintained for 7 weeks, and each cycle is 77 days

Summary: After the TPS system hollow glass has been tested for 5 aging cycles specified by the standard, both the moisture permeability index and the argon content can still meet the requirements of the national standard, and the moisture permeability index test results after 5 cycles are better than the current domestic According to the test results of the standard cycle of the traditional sealing structure, the gas content has only dropped by about 4%. The service life of the insulating glass of the TPS system is three times that of the current domestic mainstream sealing structure insulating glass.

According to the test results of five cycles in Germany, the traditional trough aluminum hollow butyl rubber has been obviously deformed and cracked, and the tps system is intact
