Silica gel contains lots of small pores.It’s surface area covers
700 square metersper gram. Its surface and shape never changewhen
saturated. Silica gel has the advantageof quick absorption speed,
non-shape changingetc. It meets the requirement of
JIS-0701standard. Thus, Silica-gel desiccant isa traditional
packing product for mildew-proof.
Character:
It is transparent and/or translucent globularparticle, which is
no-color or translucentglobular particle, which is no-color orlight
yellow, but it is allowable to bemixed with elliptical nebula
particles anda few brown particles. There is considerablelarge
interior surface area of the particles,which is nonpoisonous and
odorless. It isof high ability of absorbing water vaporand other
condensed vapors.
Application:
It is used for gas-purifying, drying,humidity adjusting a-gent and
catalyst carrier.It is also applied to refine petroleum productsand
to dryly store precision instruments,textile, food, drug and so on.
