Compare of UPVC double glazing cost ,how to do the production process, allowing it to reduce the chances of leaks? I am using a simple small-scale heat sealing machine. Want to understand the technology, many friends to the point! ! !

Below that temperature, the air layer of water vapor will condense into liquid water. Can be introduced double glazing cost : the higher the water content, the higher the air dew point temperature, when the inside surface of the glass temperature is below the dew point the air inside the air layer, the air inside surface of the glass of water would be condensation or frost. Hollow glass dew point rise is the moisture into the air from the outside layer of desiccant to absorb without being caused, there are three reasons may lead to increased dew point: (1) sealed plastic bubble memory has led to the air moisture to enter. (2) the proliferation of water vapor into the air through the polymer layers. (3) double glazing cost the effective desiccant adsorption capacity lower. 2, hollow glass dewpoint control measures (1) strictly control the production environment, production environment, the temperature mainly affected the ability and the remaining attached adsorption capacity. (2) reduce the spread of water through the polymer depends mainly on selection of low permeability coefficient of the sealant, determine a reasonable thickness of the seal, reducing double glazing cost the temperature difference inside and outside the insulating glass (that is controlled in a certain temperature range, temperature range of production without giving too large. ) (3) reduce the production process to minimize the drying time in contact with the air time, reduce the loss of Er Shi desiccant adsorption capacity have a higher adsorption capacity. (4) select the appropriate aluminum the derivative of its pore air gap is smaller, reducing the water absorption molecular sieve during operation . (5) select the appropriate drying agent to choose a high absorption rate and lasting desiccant. Is believed that through the election materials, processing, control of all aspects of the environment, the quality of insulating glass will be significantly controlled save double glazing cost .
