Declassification of hollow glass molecular sieves (3A zeolite)

"Insulating Glass 3A Zeolite" sounds strange to people, but everyone is very familiar with glass. Glass, the ancients called it glass or glass, is a colored translucent mineral. The Tang Dynasty poet Lan Yu praised it like this: "Colored with ice, nothing is separated from the dust," colored with cold ice, which means that the glass is colored, but is as transparent as the ice in the winter; nothing is separated from the dust, meaning that although it is transparent, But it seems that nothing is there, but it separates the fibers from the dust. What a poetic glass this is! The modern hollow glass is even more magical. It is a multi-layer glass made of two or more glass seals. The glass is separated by spacers with desiccant, and the edges are sealed with sealing tape. The desiccant in the spacers guarantees the space between the layers. The degree of dryness of the air plays a decisive role. The main function of insulating glass is sound and heat insulation, which reduces heat loss, thereby reducing energy consumption, improving glass transparency, achieving insulation of large-area windows, and reducing noise. This is the most used in buildings, which can save 30%-50% of the building energy consumption. Therefore, the building must be insulated with insulating glass.

Said "3A Zeolite", the molecular sieve is a crystalline silicate or aluminosilicate, composed of a silica tetrahedron or an alumino-tetrahedron, having a uniform microporous network structure and an extremely large surface area. Different types of molecular sieves can be used to separate a variety of different molecules due to their different pore sizes or shapes. According to industry experts, water is a very polar molecule. A-type zeolites have a very high affinity with water and are often used as desiccants with excellent effects. They explained that the molecular sieve we are talking about refers to the type 3A molecular sieve that can only be used to absorb water molecules. The pore size of 3A zeolite is 3 angstroms. It is mainly used to adsorb water and does not adsorb any molecules whose diameter is more than 3 angstroms. "3A zeolite." Zeolite 3A is several tens of times more dry than silica gel desiccant, alumina desiccant and any other type of clay desiccant.

The purpose of the use of insulating glass is to reduce the degree of indoor temperature affected by the external environment, sound insulation to keep the interior quiet, while the desiccant absorb moisture in the sandwich, so that the glass remains transparent under any external temperature environment, in order to ensure the realization of the above goals . Because of the nature of 3A zeolites, non-3A zeolites are strictly prohibited as desiccants for air-drying hollow glass for safety reasons.
