1. Medicine and health
PVP has excellent physiological inertia, does not participate in human metabolism, and has excellent biocompatibility, and does not form any irritation to the skin, mucous membranes, eyes, etc. From a biological point of view, the molecular structure of PVP is similar to that of a simple protein model, and even its water solubility, its ability to cooperate with some small molecules, and its ability to be precipitated by some protein precipitators such as ammonium sulfate, trichloroacetic acid, tannic acid and phenols are also soluble with proteins. As a result, PVP is widely used as an excipient in pharmaceutical preparations. Specific applications are as follows: \u2460 used as a binder in preparations \u2461 co-precipitant \u2462 as a co-solvent or crystallization inhibitor in injections \u2463 coating or film forming agent \u2464 delay agent, slow release agent controlled release of drugs can extend the action time of drugs \u2465 artificial vitreum and cornea \u2466 surgical wrap band. In addition, PVP can also be used as colorant and X-ray contrast agent; It can be used in tablets, granules, water and other dosage forms. It has the functions of detoxification, hemostasis, increasing dissolution concentration, preventing peritoneal adhesion and promoting sedimentation rate.

8. Other aspects
PVP can be used as a gelling agent for tertiary oil recovery to improve oil recovery rate. As an additive for photosensitive materials, it helps to reduce the emulsibility and enhance the overlay ability of developed images. It is used as thickener, dispersion stabilizer and bond regulator in polymer polymerization. In the paper industry as a dispersant, in acrylamide gasification reaction as a cocatalyst. PVP is currently in the separation film, light curing resin, laser disc, drag reduction coatings, building materials, steel and electroplating and other fields of application is also rising.<\/p>","protected":false},"excerpt":{"rendered":" English name\uff1aPolyvinylpyrrolidoneEnglish alias\uff1aK-30;Povidone;Pop;Polyvinylpyrrolidone K 25;Polyvinylpyrrolidone K 30;Polyvinylpyrrolidone K 90;Polyvinylpyrrolidone K 60;Polyvinylpyrrolidone-Divergan RSMolecular weight\uff1aMW:58000 PVP K-30 meidical grade ANALYSIS\u00a0\u00a0 ITEMS STANDARD ANALYSIS\u00a0 RESULTS \u5916\u89c2\/Appearance White Powder Complies \u9274\u522b\/Identification Positive Positive K\u503c\/K Value 27.0-32.0 30.2 \u6c34\u4efd\/Moisture\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u2264% 5 3.7 PH\u503c\uff085%\u6c34\u6eb6\u6db2\uff09\/PH of\u00a0\u00a05% aqueous solution 3.0-7.0 3.5 \u707c\u70e7\u6b8b\u6e23\/Residue on Ignition\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u2264% 0.1 0.02 N-\u4e59\u70ef\u57fa\u5421\u54af\u70f7\u916e\/N-Vinylpyrrolidone\u00a0\u00a0\u00a0\u00a0\u2264% 0.1 0.01 \u919b\/Aldehyde\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u2264% 0.05 0.01 \u91cd\u91d1\u5c5e\/Heavy Metal(As Lead)\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 \u2264ppm 10 \uff1c10 \u8fc7\u6c27\u5316\u7269\/Peroxide\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 \u2264ppm 400 \u00a0\uff1c400 \u6c2e\/Nitrogen\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0% 11.5-12.8 12.02 MFT.

At present, it has developed into non-ionic, cationic, anion 3 categories, industrial grade, pharmaceutical grade, food grade 3 specifications, relative molecular mass from thousands to more than one million homopolymer, copolymer and crosslinked polymer series products, and with its excellent unique properties have been widely used.PVP is divided into four stages according to its average molecular weight size,\u2026<\/p>","protected":false},"author":1,"featured_media":0,"comment_status":"open","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[3],"tags":[],"attr":[111],"class_list":["post-2439","post","type-post","status-publish","format-standard","hentry","category-problems"],"_links":{"self":[{"href":"https:\/\/www.yearnintl.com\/ko\/wp-json\/wp\/v2\/posts\/2439","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.yearnintl.com\/ko\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.yearnintl.com\/ko\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.yearnintl.com\/ko\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/www.yearnintl.com\/ko\/wp-json\/wp\/v2\/comments?post=2439"}],"version-history":[{"count":3,"href":"https:\/\/www.yearnintl.com\/ko\/wp-json\/wp\/v2\/posts\/2439\/revisions"}],"predecessor-version":[{"id":2443,"href":"https:\/\/www.yearnintl.com\/ko\/wp-json\/wp\/v2\/posts\/2439\/revisions\/2443"}],"wp:attachment":[{"href":"https:\/\/www.yearnintl.com\/ko\/wp-json\/wp\/v2\/media?parent=2439"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.yearnintl.com\/ko\/wp-json\/wp\/v2\/categories?post=2439"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.yearnintl.com\/ko\/wp-json\/wp\/v2\/tags?post=2439"},{"taxonomy":"attr","embeddable":true,"href":"https:\/\/www.yearnintl.com\/ko\/wp-json\/wp\/v2\/attr?post=2439"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}} |
