Properties:
PVA is a kind of high polymer. It
is white or light yellow floc, granular or powdery in appearance.
Its molecular formula is [CH2CHOH]n, and the molecular formula
for some of the PVA is -[CH2CHOH]n-[CH2CHOOCCH3]m-. PVA is
non-toxic, insipid and harmless. PVA is water-soluble and the
solvent provide good viscosity and film building. It can
withstand oils, lubricants, hydrocarbons and most other organic
solvents. It possesses the typical chemical properties of polyols
and can carry out process of esterification, etherealization,
acetalization etc.
Applications
A. Textile industry: PVOH is mainly
used as a warp dressing agent, textile finishing agent and the
raw material of vinylon.
B. Construction Upholstery industry **7 glue: it's used as an
additive of cement and mortar, inner and outer wall paints, and
moulding board binder.
C. Chemical industry: It's used as a polymer emulsifying agent,
dispersing agent and used to produce PVOH formal, PVOH acetal and
PVOH butyral.
D. Paper industry: It's used as an adhesive in lumbering and
paper-making industries.
E. Agriculture: It’s usually used as a soil improving agent,
pesticide reinforcing agent and PVOH thin film
F. it is used as a well-fixing agent in petroleum
exploitation.
