Information

With the improvement of national building energy-saving requirements and the improvement of people's energy-saving awareness, people gradually realize that the life of insulating glass is very important to energy-saving insulating glass, and premature sealing failure The insulating glass not only can not save energy, but will cause energy waste. The following insulating glass thickness gauge manufacturers talk about the choice of materials in insulating glass testing.

Insulating glass thickness gauge manufacturers: insulating glass material requirements

There are many insulating glass components, including sealants, desiccants, gaskets, edge sealing systems for glass-forming insulating glass, etc. The quality of the edge sealing system determines the hollowness glass life.

1. Sealant

Generally speaking, in addition to glass, sealant is the core material of the edge sealing system of insulating glass, the bonding state with glass, its own water vapor permeability, elastic modulus The properties such as quantity and elastic recovery rate directly affect the life of insulating glass, so the choice of sealant is very important.

In insulating glass sealants, butyl sealants are smaller than polysulfide sealants in terms of water-based pass rate performance. However, due to its own properties, butyl rubber has poor anti-aging properties and is easily affected by external conditions, so it cannot be used alone, and the external sealant must be protected. At the same time, the manufacturer of the insulating glass thickness gauge believes that it is a one-component plastic sealant, and the low molecular weight mineral oil material has poor corrosion resistance and is prone to swelling and dissolution. For this, the external sealant must be compatible with butyl adhesives. Prevent the movement of low molecular weight mineral oil in the environment and affect the sealing effect of insulating glass.

The insulating glass exterior sealant must have good anti-aging properties. In addition to providing protection for the inner sealant-butyl adhesive, it must have a high elastic modulus, elastic recovery and good bonding properties. Ensure good sealing of the edges, sufficient tensile and shear strength to withstand all static loads of the insulating glass support.

2. Desiccant

Due to the spontaneity of water adsorption by desiccant, in order to ensure the long-term use of insulating glass, high static water adsorption capacity and low adsorption rate are required. During the production process, the desiccant takes time from charging to closing due to technological limitations, during which the desiccant will actively absorb moisture in the air. The low adsorption rate can ensure that the desiccant adsorbs a small amount of water in the process and maintains a high residual adsorption capacity. The high static water adsorption capacity can ensure that the desiccant is absorbed by the water vapor sealed in the hollow steel and penetrated into the hollow steel through the sealant during use, so as to keep the hollow steel dry for a long time. The temperature change causes the stress inside the cavity to change, causing the glass to deform.

3. Spacer bar

In addition to providing a storage place for the desiccant, the spacer also acts as a rigid frame, effectively isolating voids in the glass formation, supporting and improving the seal of the sealant ability to improve the performance of insulating glass. Typical spacers are metal spacers, composite tapes, hybrid spacers, super spacers, etc.
