A molecular sieve

A molecular sieve

A molecular sieve is  a  combination of silicon and aluminum oxides. Simply put, these are balls ranging in size from 0.5 to 2 mm with many pores that  adsorb water vapor  penetrating  through  the side seams of the double-glazed unit into the period of  its operation.

The value of them is that  these pores have a certain diameter. Water  vapor  molecules pass through them, but  gas molecules do not pass through.  Due to this ability to selectively absorb molecules, they were called the “molecular sieve”:  they  “screen out” water vapor from, say, argon, which is filled with  the chambers of double-glazed windows for better   thermal insulation.

The most important function of the molecular sieve is  to  reliably and as long as possible  prevent moisture condensation in the space between the glasses caused by the penetration of  water vapor  into the package.

The absence of a molecular sieve will cause moisture  to condense at a low temperature on the inner surface of the  glass.

Therefore,  we conclude that the molecular sieve  is a very important part of a serviceable plastic window without defects!
