The difference between hollow molecular sieve and desiccant
Ordinary desiccant: commonly known as desiccant, it was originally used mainly in the food industry, it is a clay desiccant containing calcium chloride. The clay desiccant has never publicly claimed that it contains ingredients. In fact, this desiccant plays a major role. It is calcium chloride, not clay. The pure clay desiccant itself is not strong in water absorption, but the adsorption rate can be increased after adding calcium chloride. When the temperature reaches 30 °C , calcium chloride will form crystal water dissolved in itself, and the solution calcium chloride will show strong corrosiveness. It will first corrode the hollow aluminum strip , and then it will slightly corrode the sealant and destroy the adhesion of the insulating glass. In addition, the solution is also corrosive to the low-emissivity glass coating coated with silver film, used in hollow aluminum. There is a certain impact on the bar . Some small business enterprises, in order to save costs, will use this product, we do not agree with this product .
Hollow molecular sieve : commonly known as 3A molecular sieve, which is a high-grade desiccant, mainly used in hollow glass aluminum spacers . 3A molecular sieve produced by Hebei Xingda Insulating Glass Aluminum Strip Factory is used as a special desiccant for insulating glass, which can continuously absorb the insulating glass spacer. mist and residual organic matter, solve twisted hollow glass due to expansion or contraction caused by the crushing problems, condensation is very effective in preventing frost glass, hollow glass protection for more than twenty-five years of service life. Its effective adsorption capacity is 20 times that of clay hollow desiccant , and its average service life is eight times that of 4A molecular sieve desiccant. It meets all the performance indexes stipulated by the state. At present, 3A molecular sieve is the most ideal hollow glass desiccant on the market.
Hebei Xingda Insulating Glass Aluminum Strip Factory operates with integrity. Our business philosophy is: small profits but quick turnover, mutual benefit and win-win.
