PVA with partial alcoholysis and low polymerization degree dissolves extremely fast, while PVA with complete alcoholysis and high polymerization degree dissolves slowly. As a general rule, the degree of alcoholysis is greater than the degree of polymerization for the influence on the solubility of PVA. some can swell at room temperature in water,such as JOYFORCE 0588, 1788, 2488. The others are easily soluble in water at room temperature,such JOYFORCE PVA0599, 1799, 2699.\u00a0The PVA dissolution process is carried out in stages, namely: affinity wetting-swelling-infinite swelling-dissolution.<\/p>\n

El PVA soluble es soluble en agua; cuanto mayor es la temperatura del agua, mayor es la solubilidad, pero es casi insoluble en disolventes org\u00e1nicos. La solubilidad del PVA var\u00eda con el grado de alcoholisis y el grado de polimerizaci\u00f3n. El PVA con alcoholisis parcial y bajo grado de polimerizaci\u00f3n se disuelve extremadamente r\u00e1pido, mientras que el PVA con alcoholisis completa y alto grado de polimerizaci\u00f3n [...]<\/p>","protected":false},"author":1,"featured_media":801,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"_acf_changed":false,"footnotes":""},"categories":[43],"tags":[],"class_list":["post-800","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-blogs"],"acf":[],"yoast_head":"\n
