Product Description

Superior 3A Molecular Sieve for Optimal Glass Moisture Control

3A type molecular sieve desiccant is only suitable for insulating glass

Molecular sieve is a type of crystalline aluminosilicate mineral pellet, which is connected by oxygen bridge bonds between silicon oxide tetrahedra or aluminum oxide tetrahedra to form pore and cavity systems with molecular size (usually 0.3-2 nm). Its pore size is equivalent to that of ordinary molecules, and only molecules with a diameter smaller than the pore size are allowed to enter. Its pore size can be controlled by different processing techniques. In addition to adsorbing water vapor, it can also adsorb other gases.

According to the proportion and crystalline structure of silicon and aluminum, it can be divided into type A X-shaped Y-type molecular sieve, etc., as shown in Figure 1. According to the pore size of molecular sieves, they are divided into 3A molecular sieves, 4A molecular sieves, and 5A molecular sieves. Among them, the most commonly encountered molecular sieve in insulating glass is 3A molecular sieve.
