“Porous
Materials” is
the general term for the diversified materials with
micropores AION presents.
On AION's product lines are PVA sponges, which hold the central
position
as basic technology, PU sponges and PVA films. They represent the integration of porous materials with sophisticated features, created
by
combining high grade and high value-adding technologies, and are
clearly distinct from common sponge materials. |
|
PVA SPONGE…It is
a porous material with continuous open pores made from
polyvinyl alcohol.
Since the diameter and density of the pores can be freely controlled
and the
sponge can be colored and shaped to the purposes, a wide choice of
articles
is given to the users. Also excellent abrasion resistance and
chemical
resistance allow PVA sponge to be widely used both in industrial and
daily-use applications. |

Ostensibly PVA
sponge looks like a solid block. Seen microscopically, however,
about 90 percent of its volume is completely hollow, and the
substrate that embraces the hollowness (pores) forms a
three-dimensionally reticular structure, making the entire pores
perfectly continuous. This integral structure is the greatest
characteristic of PVA sponge which allows it various functions. |

PVA sponge is, quite
different from
common sponges such as urethane
sponge, remarkably hydrophilic, and
capillarity generated by its three-dimensional network of micropores
produces outstanding water absorbent
and water retention properties.Coming in contact with water makes the
structure start absorbing water at an
amazing speed, rapidly taking the water
into itself and holding it securely. |
|
 |
|
 |
When wet, PVA
sponge is soft, supple and
resilient. So in scrubbing or wiping, it
leaves no scratches or scrapes on the surface of the pieces it is
working on.
Because of the soft and supple characteristics, it is suited for
industrial uses such as cleaning of hard disks or silicon wafers as
well as the cleaning process of sophisticated precision instruments
or optical devices. |
