Convective transfer is due to the temperature difference between both sides of the glass having a hollow glass manufacturers, causing air in the cold side of one surface of the rise and drop of heat insulating glass, generating air convection, caused by the loss of energy. The reasons for this phenomenon are a few: First, seal the glass and the surrounding frame system adverse laminated insulating glass, causing gas inside and outside of the window frame can be exchanged directly convection, resulting in the loss of energy; hollow glass is dew point rise caused by external moisture into the air desiccant layer without being absorbed, there are three possible reasons for increased dew point: (1) memory sealant bubbles, causing air to enter the water. (2) diffusion of water vapor into the air through the polymer layer. Effective adsorption capacity (3) low desiccant. (1) strictly control the production environment temperature mainly affects the production environment and the ability to attach the remaining adsorption capacity. (2) reduce the moisture diffusion through the polymer sealant mainly by selecting low permeability coefficient, determine a reasonable seal thickness, reducing the difference in temperature inside and outside of the hollow glass (ie control within a certain temperature range temperature range of production without giving too much) .
