3A molecular sieve desiccant can do it? A: The need to be cautious! Now desiccant for food on the market is mainly fiber desiccant, desiccant Jiangxi zeolite mineral, lime and silica gel desiccant desiccant. If you can prove that non-toxic materials, and use with food packaging materials packaging material should also be used for food. Because desiccant type of business is not classified as food manufacturers, but the general packaging business, so there is no relevant state departments certification standards Xi'an molecular sieve, it is no food and drug production licenses. The next section, I will give you talk about how the theory can be used to identify whether the Food and Drug desiccant? Shanghai Co. --3A new molecular sieve sieve! Zeolite professional R & D and manufacturing! Moisture sieve what type of situation? Determination of water content The best choice is to use molecular sieves 3A molecular sieves, as 3A molecular sieves is relatively not only adsorbed water adsorbed other gas. Calculation method: take a sufficient amount of a molecular sieve from the weight of the weighing of a; molecular sieve together with the measured object is placed in a confined space, Shenyang sieve, sieve for 24 hours after the removal, saying that was the weight b. b-a is the water content. The method described above is only a rough measure, because 3A molecular sieve adsorption of other gases without absorption is relative, but not very demanding if the above method is enough, because 3A molecular sieve adsorption of other gases can almost be said to be minimal. Henan sieve sieve _ _ new new zeolite molecular sieves by Shanghai Limited. Shanghai new molecular sieve Limited (www.molsionms.com) strong, credible, in Shanghai's Songjiang District elemental industry has accumulated a large number of loyal customers.
