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\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-1428","post","type-post","status-publish","format-standard","hentry","category-problems"],"_links":{"self":[{"href":"https:\/\/www.yearnintl.com\/ko\/wp-json\/wp\/v2\/posts\/1428","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=1428"}],"version-history":[{"count":4,"href":"https:\/\/www.yearnintl.com\/ko\/wp-json\/wp\/v2\/posts\/1428\/revisions"}],"predecessor-version":[{"id":1588,"href":"https:\/\/www.yearnintl.com\/ko\/wp-json\/wp\/v2\/posts\/1428\/revisions\/1588"}],"wp:attachment":[{"href":"https:\/\/www.yearnintl.com\/ko\/wp-json\/wp\/v2\/media?parent=1428"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.yearnintl.com\/ko\/wp-json\/wp\/v2\/categories?post=1428"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.yearnintl.com\/ko\/wp-json\/wp\/v2\/tags?post=1428"},{"taxonomy":"attr","embeddable":true,"href":"https:\/\/www.yearnintl.com\/ko\/wp-json\/wp\/v2\/attr?post=1428"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
