Polyvinylpyrrolidone (PVP) is a synthetic polymer that belongs to the class of polyvinyl compounds. It is also known as povidone. PVP is a versatile substance with various applications in industries such as pharmaceuticals, cosmetics, and food. The number “10” in your question is not clear. It could refer to the molecular weight or a specific grade of PVP. PVP is available in different molecular weights or viscosities, and each grade has specific properties suitable for various applications. In the pharmaceutical industry, PVP is commonly used as a binder, disintegrant, and film-forming agent in tablet formulations. It improves the dissolution of active pharmaceutical ingredients and enhances the overall stability of tablets. In cosmetics, PVP is used as a hair fixative in hairsprays, gels, and mousses. It provides the desired hold and styling effects without causing stiffness or flaking. PVP is also used in skincare products as a film-forming agent, helping to…

The specific production process should bePVP production process:Acetylene process is the mainstream PVP production process.The production process of PVP can be divided into acetylene method and gamma-butyrolactone method.In the acetylene process, acetylene and α-pyrrolidone are used to produce NVP (n-vinylpyrrolidone), and then polymerize to produce PVP.The γ-butyrolactone method is to produce hydroxyethyl pyrrolidone by γ-butyrolactone method and ethanolamine, and then dehydrate to produce PVP.Acetylene process is the mainstream large-scale industrial production process at present. It has certain advantages over gamma-butyrolactone method in product quality, production yield (mature process), and economy (cheap and easy to obtain raw materials). Gamma-butyrolactone method is more suitable for the production of small and medium-sized processes. In acetylene process, 1, 4-butanediol (BDO) is synthesized from acetylene and formaldehyde, and after catalytic dehydrogenation, ya-butanolactone, cyclogenesis, ammonolysis, acetylene addition and other reactions, NVP is obtained.The monomer vinylpyrrolidone (NVP) was prepared by bulk polymerization and solution polymerization.In the process…

Polyvinylpyrrolidone is a kind of high molecular compound, which is widely used in the medical field. First, it can be applied in the field of drug sustained release. Polyvinylpyrrolidone can help slow the release of the drug, so that the effect of the drug is maintained at the therapeutic level for a long time, and thus reduce the toxic side effects of the drug.Secondly, polyvinylpyrrolidone is also suitable for the production of medical contact lenses. Due to its high stability in water, it is very useful in the manufacture of contact mirrors. It can be used to make soft contact lenses, which can improve the oxygen permeability of contact lenses and reduce eye discomfort.In addition, polyvinylpyrrolidone can also be used in the field of neural tissue engineering. The researchers found that it can be used as a substrate to improve the growth of nerve tissue, so it is expected to…

Abstract: Viscosity and thixotropic index are simple and quantitative characterizations of rheological properties of carbon black dispersions. Carbon black dispersions with different rheological properties were prepared by adding different relative molecular weights and different amounts of PVP into the matrix of carbon black dispersions. The viscosity, shear rate curve and thixotropic index of each carbon black dispersions were analyzed to prove the influence of PVP on their rheological properties. The results show that the parent carbon black dispersion has shear thinning behavior. After adding PVP, the apparent viscosity and thixotropic index of the system can be significantly improved. The apparent viscosity of the system decreases linearly with increasing temperature and is temperature-dependent.Carbon black pigment dispersion is a colloidal dispersion system formed by dispersing carbon black into water with dispersant, which is widely used in paint, ink, plastic, rubber and other fields. Generally speaking, fluids can be divided into Newtonian fluids…
