The insulating glass molecular sieve can absorb water and residual organic matter in the insulating glass at the same time, making the insulating glass smooth and transparent even at very low temperature. at the same time, it can fully reduce the strong internal and external pressure difference of insulating glass due to the great change of temperature difference between season and day and night. The insulating glass molecular sieve also solves the problem of distortion and breaking caused by the expansion or shrinkage of the insulating glass and prolongs the service life of the insulating glass. Absorb the moisture in the hollow glass cavity, reduce the dew point and prevent the glass from fogging so as to achieve the purpose of heat preservation, energy saving and noise reduction.

Why only 3A molecular sieve is qualified to be used in hollow glass: (1) 3A molecular sieve only absorbs water and does not absorb oxygen and nitrogen in the air. (2) 3A molecular sieve is weakly alkaline and its PH value is 10. 5, it will not cause damage to the aluminum bar in the insulating glass. (3) the water absorption rate of 3A molecular sieve is fast, and the water absorption rate is 0. 04g/s . (4) the water absorption of 3A molecular sieve is large, and the water absorption is ≥ 20%. (5) 3A molecular sieve does not produce hydrolytic absorption at room temperature. Can 4A molecular sieve be applied to insulating glass? 4A molecular sieve adsorbs oxygen and nitrogen in addition to the water in the air, which will cause the hollow glass to be affected by the change of external temperature and pressure. convex or concave (when the external temperature increases, 4A molecular sieve will release the adsorbed nitrogen and oxygen so that the internal pressure of the insulating glass is stronger than the external pressure, and the hollow glass will be convex. When the external temperature decreases, 4A molecular sieve absorbs nitrogen and oxygen so that the external pressure is greater than the internal pressure of hollow glass, and the convex phenomenon of hollow glass disappears or concave). Such a convex and concave will affect the sealing performance of the insulating glass, and what is more serious is that the hollow glass will be damaged. Therefore, 4A molecular sieve is not suitable for insulating glass.

The correct use of insulating glass molecular sieve: 1. Insulating glass special molecular sieve should be sealed and preserved before use. It is found that the packaging is damaged and can not be used. If you have opened the package and haven't finished using it, you can't pack it by yourself before using it. 2. Filling should be carried out in a dry and dust-free room. 3. After opening the package, the molecular sieve is strictly forbidden to be exposed to the air for a long time, from filling to gluing and lamination should be completed continuously in a short time. The aluminum partition frame filled with molecular sieve should synthesize insulating glass within 45 minutes. 4. There shall be no air leakage on all sides of the sealed hollow glass. 5. after the hollow glass laminate is glued, it is strictly forbidden to be exposed to the sun. 6. The molecular sieve filling machine is good and airtight. In short, to achieve: regular testing, drying, indoor, dust-free, quick installation, prevent air leakage and exposure.
