Unite into between-line spacing, centre is filled with gas.Glass plate can be ordinary plate glass, safety glass or Low-E glass, this basis
Place to use and the role of double glazing and select.Gas between glass plate must be dried, and can be air, argon gas
Or other special gas, it is interior to keep gas to dry with molecular sieve.Edge seal system species is various, predominantly spacer bar (frame),
Fluid sealant and molecular sieve.Spacer bar plays separate glass sheets between layer glass, and surrounding carries out edge sealing with fluid sealant,
Make bonding glass together and prevent that gas is excessive in layer.
When having the temperature difference inside and outside double glazing, the conduction heat of intermediate portion position and edge is different.Hollow
The edge of glass, due to sealing system and glass plate close contact, so being the conduction heat transfer between multilayer planomural.It is spaced web
Greatly, initially use aluminum parting bead thermal conductivity factor is big, thermal resistance is small for influence of the thermal conductivity factor of matter to thermal resistance.To hollow space
Speech, air layer thickness is closely sized to spacer bar, so the ratio between their thermal resistance is also similar to the ratio of their thermal conductivity factors.It is pure
The thermal conductivity factor of aluminium is 202W/m K, as the thermal conductivity factor of aluminium alloy also between 130-150W/m K, so, the thermal resistance of edge
Far smaller than center section.During winter, the thermal resistance of its peripheral portion of building double glazing is small, and temperature drop is obvious.Due to room
The glass plate that the interior moisture having in certain humidity, air encounters lower temperature is just condensed, and is produced at the edge of double glazing
Condense frost, and this had not only influenceed attractive in appearance but also encapsulant is caused damage.
