The invention provides a
fiber humidity adjusting board. The
fiber humidity adjusting board is obtained by soaking a composite board in a
humidity adjusting liquid, and the composite board is composed of a
fiber material treated by
carboxylation and porous
inorganic particles dispersed in the fiber material, wherein the
mass of the
inorganic particles accounts for 5 to 30 percent of the
solid content of the fiber, and the
inorganic particles adopt one or the combination of
silica gel, clay, concavo-convex rods, diatomaceous earth,
activated carbon, wood
charcoal and
bamboo charcoal. The invention has the advantages that the fiber humidity adjusting board is a precise humidity adjusting product, when the
ambient humidity changes, response can be rapidly made, and through
moisture absorbing and releasing, the
ambient humidity can be balanced, so as to maintain the humidity in the environment to be constant and ensure that the phenomena of
wetting, mould damage or
drying and
cracking of the stored articles can not occur within the adjusting environment. A strap-shaped fiber humidity adjusting board is adopted, which can be
cut arbitrarily; the humidity adjustment can be performed in function, and the
moisture holding amount can reach and surpass the equivalent international humidity adjusting products. The fiber humidity adjusting board adopts non-toxic, harmless and recoverable
raw material, and the fiber humidity adjusting board is a new-generation green and environment-friendly product.
