Pharmaceutical empty moisture proof tube

Nov 06 , 2018

Pharmaceutical empty moisture proof tube is composed of low-density polyethylene (LDPE) bottle cap skeleton, desiccant and cardboard. Desiccant is used for moisture and mildew of medicines and foods. The commonly used desiccant can be divided into a physical adsorption desiccant and a chemical adsorption desiccant, and the silica gel desiccant in the physical adsorption desiccant meets the US FDA standard and is verified to be harmless to the human body. Silica gel desiccants physically adsorb water molecules in their structures.

Commonly used desiccants in medical moisture-proof bottles are quicklime, magnesium chloride, calcium chloride, soda lime, phosphorus pentoxide, etc., absorbing water molecules to change their chemical structure and become another substance. Molecular sieves are another commonly used desiccant. The molecular sieve is a crystalline silicate or aluminosilicate, which is a channel and cavity system formed by a silicon oxytetrahedron or an aluminoxy tetrahedron connected by an oxygen bridge. It can be divided into pore size by high-efficiency desiccant, selective adsorbent, catalyst, ion exchanger, etc. The molecular sieves with pore size less than 2nm, 2-50nm and more than 50nm are called microporous, mesoporous and macroporous molecular sieve respectively.
