First, the characteristics of POvidone as an adhesivePovidone (PVAc) is a colorless, transparent polymer commonly used in the preparation of glues and adhesives. It has good mechanical properties, chemical stability and bonding properties, and can be bonded with cellulose materials, wood, metal and other materials. However, the hydrothermal properties of POvidone are relatively poor, and it is easy to decompose in water, so it is not suitable for bonding work in humid environments. Second, the characteristics of copovidone as an adhesivePolypovidone (PVP\/VA) is a copolymer of polyvinylpyrrolidone and polyvinyl alcohol acrylate, which has excellent hydrothermal properties, corrosion resistance and biocompatibility, and is widely used in medical devices, food packaging and cosmetics industries. Compared with POvidone, the mechanical properties of copovidone are slightly inferior, but its hydrothermal stability is strong, it does not decompose in water, and it can perform bonding work in humid environments.The principle of copovidone as a binderCopovidone\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":[125],"class_list":["post-1809","post","type-post","status-publish","format-standard","hentry","category-problems"],"_links":{"self":[{"href":"https:\/\/www.yearnintl.com\/ko\/wp-json\/wp\/v2\/posts\/1809","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=1809"}],"version-history":[{"count":3,"href":"https:\/\/www.yearnintl.com\/ko\/wp-json\/wp\/v2\/posts\/1809\/revisions"}],"predecessor-version":[{"id":1813,"href":"https:\/\/www.yearnintl.com\/ko\/wp-json\/wp\/v2\/posts\/1809\/revisions\/1813"}],"wp:attachment":[{"href":"https:\/\/www.yearnintl.com\/ko\/wp-json\/wp\/v2\/media?parent=1809"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.yearnintl.com\/ko\/wp-json\/wp\/v2\/categories?post=1809"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.yearnintl.com\/ko\/wp-json\/wp\/v2\/tags?post=1809"},{"taxonomy":"attr","embeddable":true,"href":"https:\/\/www.yearnintl.com\/ko\/wp-json\/wp\/v2\/attr?post=1809"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
