Molecular sieve for double-glazed windows

The molecular sieve in a double-glazed window acts in a role, a moisture absorber in internal air space between glasses. On the physical properties the molecular sieve is capable to absorb not only molecules of liquid, but also other molecules, for example gases, owing to the cellular - crystal structure. The crystal cell size, is more than water molecule that allows molecules of water to get into it. Diameter of cells of a sieve is equal 3-5 Angstroms (no more than 3 Angstrom are better). Cells, are not capable to let in themselves molecules of gases which sizes exceed diameter of their time. However, if a cell more than 5 Angstrom, then molecules of such gases of air as argon, krypton, xenon, nitrogen and other can be occluded by a sieve and in a double-glazed window air is strongly discharged that can lead to its destruction, especially in cold temperature.

Unlike silica gel, modern molecular a sieve do not absorb nitrogen molecules from air therefore it is possible to avoid a deflection of glasses in a package at negative temperatures and a curve of glasses at considerable above-zero temperatures of environment. It reduces the internal tension of glasses and increases double-glazed window service life. Molecular a sieve are standardly made during reaction of solutions of hydroxide of aluminum, the caustic soda and silicate of sodium, kristallizuyemy then to molecular sit with a certain size of a time. Crystals are formed in granules, dried up and calcinated. Then granules are sorted depending on the size of particles and packaged, on 25 kg a package of tight waterproof packing, in a cardboard box. Molecular a sieve are usually used for production of double-glazed windows for the purpose of prevention of condensation of moisture between glasses. By production of a molecular sieve special solvents which are brought in a design during production, and also modern binding materials the raising mechanical durability and resistance to attrition of granules of a sieve that in turn, allows to exclude dust formation are used. Standard range of diameter of a molecular sieve fluctuates from 0,5 to 2,5 mm.
