Frequently
Asked Questions
What is PVOH 823G?
PVOH 823T is a partially alcoholized,
medium molecular weight polyvinyl
alcohol (PVOH)
product with
excellent solubility, film forming,
and other properties. In addition,
PVOH 823T is known
for its
ultra-high purity and ultra-low ash
content. The high purity ensures
stability and
reliability, allowing
it to excel in demanding applications;
the low ash content helps to reduce
impurities or
contaminants that
may be generated during the product's
use, further enhancing its application
value.
What is PVOH 823G used for?
Paper industry: It can be used as a wet
strength agent or other functional
additive in the
papermaking
process.
Inkjet industry: Its
film-forming properties and water
resistance make it an
ideal
component in inkjet ink formulations.
It can also be used in the
field of adhesives,
cosmetics, oil
well cementing, etc.
How is PVOH 823G packaged and stored?
Packaging: Sealed with materials with
moisture-proof properties, weight
25kg/bag.
Storage：The
storage place should be kept dry, cool
and ventilated, avoiding direct
sunlight and high
temperature.
How is PVOH 823G produced?
The polyvinyl alcohol is first mixed
with an alcoholizing agent and
partially alcoholized;
then, the
partially alcoholized PVOH is
subjected to post-treatment, such as
neutralization and
washing, to remove
unreacted alcoholizing agents and
by-products. After removing impurities
from the product,
the purified
PVOH 823G is adjusted to the desired
particle size range by processes such
as grinding or
crushing.
Finally, the product is dried to
remove excess moisture to ensure
product stability and
storage.
What are the safety precautions for the
use of PVOH 823G ?
PVOH 823T itself is a non-toxic,
odorless, non-polluting, and
environmentally friendly
product. However,
when using, appropriate protective
equipment such as masks and gloves
should be worn, and
the operating
instructions in the product manual
should be followed.
In addition, hazardous situations such
as fire or explosion may occur under
certain specific
circumstances, such as exposure to
high temperatures and sources of
ignition, so ensure that
the storage
environment is away from sources of
ignition and high-temperature areas.
