A desicсant is a vital component in a glass unit, because it prevents the appearance of moisture inside the glass unit by adsorbing water molecules. Desicсant inside the glass unit can appear either at the production stage or after a long-lived glass unit and it is connected with the aging of the sealants in the glass unit: micro cracks appear that can penetrate water vapor.
The desicсant is poured into the cavity of the spacer frame, on the inner side of which there is a perforation, which ensures contact of the desiccant with air in the inter-glass spaces. Molecular sieves can also be used as desicсant.
A molecular sieve is a synthetic material in the form of granules with tiny pores of a certain diameter: 3, 4, 5 or 10 Angstroms (1 Angstrom = 10-10 m). At making of glass units they use molecular sieves, the pore size of which is 3Å = 0.3 microns, which allows the substance to adsorb water vapor molecules, while inert gases, that are used to fill the space of insulating glass units and have larger molecules, cannot be absorbed.
WinStyle offers the following types of desicсant:
Molecular sieve
Zibo Natergy Chemical Industry Co (China) – ZIBO NATERGY
Molecular sieve of the ZIBO NATERGY trademark has won a leading position in the markets of many European countries as a product that guarantees quality. The composition of the sieve is a crystalline aluminosilicate with binding materials and the absence of hazardous components. The product is constantly undergoing quality control in the laboratory and meets all the technical requirements. At the use a product is safe and does not have any harmful effects.
It is certified with “ift Rosenheim”, which confirms the high quality of the molecular sieve and recommends it as the best for use in glass units.
