Application


Under the catalytic action of acid, polyvinyl alcohol can condense with formaldehyde, butyraldehyde, glyoxal or other aldehydes to produce polyvinyl alcohol acetal with stronger water resistance, adhesion and mechanical strength (such as PVAF and PVB), which is widely used in construction, coating, adhesives, safety glass interlayer and other fields.The viscosity of acetal increased with the increase of PVA polymerization degree.Polyvinyl alcohol (PVA) is an excellent protective colloid and dispersant for the production of latex (white glue) by homopolymerization of vinyl acetate or co-polymerization with other monomers.Generally with the increase of polyvinyl alcohol polymerization degree, the emulsion viscosity increased.Partially alcoholized POLYvinyl alcohol (17-88) is used in combination with fully alcoholized polyvinyl alcohol (such as 17-99, 19-99, etc.). The use of partially alcoholized polyvinyl alcohol can increase the stability of the emulsion, while the use of fully alcoholized polyvinyl alcohol can increase the water resistance of the emulsion.
