Comment mesurer la qualit\u00e9 de la r\u00e9sine dans l'encre ?<\/strong><\/h1>\n

Il existe de nombreux indicateurs permettant de mesurer les propri\u00e9t\u00e9s physiques et chimiques d'une r\u00e9sine. Pour l'industrie des encres, les points suivants devraient pr\u00e9senter un int\u00e9r\u00eat.<\/p>\n

(1) la viscosit\u00e9 de la r\u00e9sine
\nLa viscosit\u00e9 de la r\u00e9sine affectera largement la viscosit\u00e9 de l'encre, l'importance de sa viscosit\u00e9 doit \u00eatre prise en compte lors du choix d'une r\u00e9sine.<\/p>\n

 <\/p>\n

(2) La solubilit\u00e9 de la r\u00e9sine dans le solvant
\nDans la production d'encre, il est n\u00e9cessaire d'ajouter une certaine quantit\u00e9 de solvant dans la r\u00e9sine pour ajuster la viscosit\u00e9 et d'autres indicateurs. Par cons\u00e9quent, la r\u00e9sine peut \u00eatre compl\u00e8tement dissoute dans le solvant s\u00e9lectionn\u00e9 ou dans l'huile min\u00e9rale, ce qui constitue la condition de base pour la production d'encre.<\/p>\n

(3) la lib\u00e9ration du solvant dans la r\u00e9sine
\nLa lib\u00e9ration du solvant dans la r\u00e9sine fait r\u00e9f\u00e9rence \u00e0 la vitesse \u00e0 laquelle le solvant est lib\u00e9r\u00e9 de la r\u00e9sine. Cela affecte la vitesse de s\u00e9chage de l'encre. Ce facteur est li\u00e9 \u00e0 la r\u00e9sine elle-m\u00eame, \u00e0 la volatilit\u00e9 du solvant qui est plus ou moins bonne, mais aussi \u00e0 la r\u00e9sine et au solvant m\u00e9lang\u00e9s au processus de pr\u00e9paration et \u00e0 d'autres facteurs.<\/p>\n

(4) La couleur de la r\u00e9sine
\nLa r\u00e9sine doit \u00eatre un liquide incolore ou clair, afin d'\u00e9viter que la couleur de l'encre ne soit due \u00e0 la couleur de la r\u00e9sine.<\/p>\n

(5) R\u00e9sistance \u00e0 l'eau de la r\u00e9sine
\nLa r\u00e9sistance \u00e0 l'eau de la r\u00e9sine affectera la r\u00e9sistance \u00e0 l'eau de l'encre, en particulier dans l'encre d'impression offset, une mauvaise r\u00e9sistance \u00e0 l'eau de l'encre entra\u00eenera une \u00e9mulsification, une plaque de p\u00e2te, pas sous l'encre et d'autres ph\u00e9nom\u00e8nes. Les encres \u00e0 base d'eau utilis\u00e9es dans la r\u00e9sine requi\u00e8rent une bonne performance de dilution de l'eau, mais le substrat apr\u00e8s le film ne peut pas \u00eatre dissous dans l'eau.<\/p>","protected":false},"excerpt":{"rendered":"
