ClayAl2O3 • 2SiO2 • 2H2O Nanoparticle /Nanopowder CAS Number : 1332-58-7
1. Strong hygroscopic power ... It is superior in hygroscopic ability in low humidity range necessary especially for maintaining the quality of foods and preventing corrosion of metal products. 2. Stability ... It is chemically inert and stable substance. There is no water solubility, corrosivity, deliquescence and shape change after moisture absorption. 3. Economicality ... It is a desiccant processed and refined natural clay mineral, and it is inexpensive. The main structure of clay (bentonite) The crystal structure of montmorillonite consists of three layers of silicic acid tetrahedral layer - alumina octahedral layer - silicate tetrahedral layer stacked, the unit layer having a thickness of about 10 Å (1 nm), a spreading of 0.1 It has a very thin structure ~ 1 μm and has a large surface area. Since it physically adsorbs water vapor between its pores composed of micropores, it will not deliquesce even when it is saturated.
The SN series is a desiccant for industrial use that is compact and economical using naturally produced clay mineral bentonite clay (NaturaSorb ® ) . It exhibits excellent hygroscopic capability for moisture proof of foods, electronic parts, precision machinery and others.
