The influence of moisture on two-component polyurethane is mainly reflected in the following aspects:1. Reduced reaction speed: Moisture reacts with the isocyanate component, reducing the content of the effective component and affecting the curing speed.2. Reduced hardness: Moisture participates in

1. Advantages and disadvantages of distillation dryingDistillation technology is to remove moisture and other volatile impurities through heating, evaporation, condensation, collection and other steps. It is suitable for drying a large amount of ethanol.However, it consumes a lot of heat energy, if

1. Advantages of molecular sievePrecise selective adsorption:Molecular sieve can selectively adsorb water molecules without affecting the existence of acetone molecules.High adsorption capacity:Molecular sieve has very high adsorption capacity and can achieve efficient removal of water in a relative

CHEMXIN 13X Molecular Sieve, also known as sodium X molecular sieve, has a crystal pore size of about 1 nm. Compared with type A molecular sieve, 13X molecular sieve has larger pore size and pore volume, and static water adsorption can reach 26%, which has excellent performance in drying and purific
