Insulating glass desiccant

The insulating glass desiccant is mainly suitable for adsorbing moisture and gas in the interlayer gas of the insulating glass, preventing the glass from fogging, keeping the insulating glass smooth and transparent even at very low temperatures, improving the thermal insulation and sound insulation performance of the insulating glass, and fully extending the service life of the insulating glass. service life.

Product introduction

Insulating glass desiccant has the following advantages

1) Ultra-low packaging moisture content ensures that the desiccant has strong water absorption performance.
2) The super deep adsorption capacity can ensure that the moisture in the glass interlayer is fully absorbed, avoid condensation, and fully ensure the thermal insulation performance of the insulating glass.
3) Ultra-low powder fallout ensures the beautiful light-transmitting performance of insulating glass.
4) Ultra-low nitrogen adsorption capacity ensures that the insulating glass will distort and deform under different temperature changes, causing the glass to burst.
5) Qualified bulk density ensures that the filling amount of desiccant is controlled within the most economical and reasonable range.
6) Reasonable acidity and alkalinity to ensure that the insulating glass spacers are not easily corroded and salted out.
7) High crushing strength, which reduces the possibility of breakage during the filling process due to insufficient strength, resulting in the formation of slag, dust, and glass contamination.
8) Low static electricity ensures that the desiccant is adsorbed on the pipe wall and blocks the pipe when the machine is filled.
9) To ensure product quality, only 3A molecular sieves are used as raw materials, and other types of molecular sieves are not added, which will not cause the "breathing" phenomenon of the insulating glass and damage the glass.
