About Other Aspects Of Polyvinylpyrrolidone

Detergent
PVP has anti-dirt re-deposition properties and can be used to prepare transparent liquid or heavy-duty detergents. Adding PVP to detergents has a good anti-color transfer effect and can enhance the cleaning ability. When washing fabrics, it can prevent synthetic detergents from damaging Skin irritation, especially for synthetic fibers, is more prominent than carboxymethylcellulose (CMC) detergents. PVP can be compounded with borax and used as an active ingredient in phenolic disinfectant cleaner formulas. The detergent compounded of PVP and solid hydrogen peroxide has the functions of bleaching and killing germs.
Textile
PVP has a good affinity with many organic dyes. It can be combined with hydrophobic synthetic fibers such as polyacrylonitrile, ester, nylon and fibrous materials to improve the dyeing power and hydrophilicity. Kirsh Y E et al. reported that after graft copolymerization of PVP and nylon, the fabric produced has improved wet wrinkle resistance and moisture resistance.
Paints and Pigments
Paints and coatings coated with PVP form a transparent film without affecting the original color, improve the gloss and dispersion of coatings and pigments, improve thermal stability, and improve the dispersion of inks and inks.
Polymer surfactant
As a polymer surfactant, polyvinylpyrrolidone can be used as a dispersant, emulsifier, thickener, leveling agent, particle size regulator, anti-re-sedimentant, coagulant, co-solvent and detergent in different dispersion systems. agent.
Catalyst preparation
As an active agent to stabilize colloidal particles, it is used in the preparation process of core-shell catalysts.
other aspects
PVP can be used as a gelling agent for tertiary oil recovery to improve the oil recovery rate of oil fields. As an additive to photosensitive materials, it helps reduce latex density and enhance the coverage of developed images. In the polymerization process, it serves as a thickener, dispersion stabilizer and adhesion regulator. It is used as a dispersant in the papermaking industry and as a cocatalyst in the propylene amine gasification reaction. The application of PVP in separation membranes, light-curing resins, laser discs, drag-reducing coatings, building materials, steelmaking and electroplating is also on the rise.
