Le plus grand avantage des encres \u00e0 base d'eau est la r\u00e9duction \u00e9vidente des \u00e9missions de COV (compos\u00e9s organiques volatils) dans l'atmosph\u00e8re, ce qui permet de r\u00e9duire efficacement les effets nocifs des solvants sur l'homme et la pollution des produits d'emballage, et convient particuli\u00e8rement \u00e0 l'impression d'emballages de produits alimentaires, de boissons, de produits pharmaceutiques, de cigarettes et d'autres produits soumis \u00e0 des exigences strictes en mati\u00e8re d'hygi\u00e8ne. Toutefois, en raison de la nature de leurs composants, les encres \u00e0 base d'eau ont une caract\u00e9ristique particuli\u00e8re : elles ont tendance \u00e0 mousser. La formation de mousse affecte le bon d\u00e9roulement du processus d'impression et la qualit\u00e9 du produit imprim\u00e9.<\/p>\n<p>&nbsp;<\/p>\n<p>La mousse est un syst\u00e8me de dispersion de gaz dans un liquide. La mousse est la formation d'une masse de gaz entour\u00e9e d'un film liquide, et le processus de destruction de la mousse consiste \u00e0 s\u00e9parer le gaz du film liquide, d'\u00e9pais en fin, jusqu'\u00e0 la rupture du processus. Les facteurs affectant la stabilit\u00e9 de la mousse d\u00e9pendent principalement de la vitesse d'amincissement du film liquide (c'est-\u00e0-dire le taux de perte de liquide dans la couche liquide) et de la solidit\u00e9 du film liquide.<\/p>\n<p>&nbsp;<\/p>\n<p>Lors de la formation de mousse, la surface du liquide augmente, l'\u00e9nergie du syst\u00e8me augmente ; lors de la destruction de la mousse, la surface du liquide diminue, l'\u00e9nergie du syst\u00e8me diminue ; du point de vue \u00e9nerg\u00e9tique, la r\u00e9duction de la tension superficielle du liquide favorise la formation de mousse, tandis qu'une tension superficielle \u00e9lev\u00e9e du liquide ne facilite pas la formation de mousse. Cependant, une faible tension superficielle ne contribue pas n\u00e9cessairement \u00e0 la stabilit\u00e9 de la mousse. Ce n'est que lorsque le film liquide a une certaine r\u00e9sistance qu'il peut former des bulles poly\u00e9driques, une faible tension superficielle contribuant \u00e0 la stabilit\u00e9 de la mousse.<\/p>\n<p>&nbsp;<\/p>\n<p>L'encre \u00e0 base d'eau est une encre liquide, beaucoup plus fine que l'encre offset, dans le processus de transfert de l'encre d'impression, elle est facile \u00e0 m\u00e9langer au gaz et \u00e0 g\u00e9n\u00e9rer de la mousse. L'encre \u00e0 base d'eau est compos\u00e9e de r\u00e9sine en solution ou en \u00e9mulsion, d'eau et d'une petite quantit\u00e9 d'\u00e9thanol et d'additifs. La r\u00e9sine doit \u00eatre dissoute dans l'eau par r\u00e9action avec l'ammoniaque. Cette r\u00e9sine soluble dans l'eau a une structure semblable \u00e0 celle du savon et produit facilement des bulles. En outre, afin d'am\u00e9liorer l'adh\u00e9rence des encres \u00e0 base d'eau au substrat, il est n\u00e9cessaire d'ajouter des surfactants pour r\u00e9duire la tension superficielle du syst\u00e8me, et une tension superficielle plus faible favorisera la formation de bulles. Par cons\u00e9quent, il est souvent n\u00e9cessaire d'ajouter des antimousses lors de l'impression avec des encres \u00e0 base d'eau.<\/p>\n<p>&nbsp;<\/p>\n<p>L'application d'antimousses est en conflit avec les mesures visant \u00e0 am\u00e9liorer la stabilit\u00e9 de la mousse. Certains antimousses sont des r\u00e9actions chimiques permettant d'atteindre l'objectif de l'antimousse (comme l'acide ou les sels de calcium qui peuvent d\u00e9truire le film de savon), tandis que la plupart des antimousses r\u00e9duisent davantage la tension superficielle du syst\u00e8me, de sorte qu'ils sont faciles \u00e0 \u00e9taler et \u00e0 adsorber \u00e0 la surface du liquide, r\u00e9duisant ainsi la force du film superficiel du liquide pour atteindre l'objectif de l'antimousse. Les types d'antimousses sont divers : outre les alcools, les acides gras, les phosphates, les amides, etc., l'huile de silicone est \u00e9galement un excellent antimousse couramment utilis\u00e9.<\/p>\n<p>&nbsp;<\/p>\n<p>Elle peut \u00eatre utilis\u00e9e dans des syst\u00e8mes aqueux et non aqueux. La tension superficielle de l'huile de silicone est extr\u00eamement faible et lorsqu'elle est ajout\u00e9e \u00e0 des syst\u00e8mes aqueux, elle sera pr\u00e9f\u00e9rentiellement adsorb\u00e9e sur le film liquide, de sorte que le film form\u00e9 a une tension superficielle inf\u00e9rieure \u00e0 celle de la surface du film original formant des bulles. En r\u00e8gle g\u00e9n\u00e9rale, il est plus probable que cela produise des bulles, mais comme l'antimousse \u00e0 base d'huile de silicone est un hydrocarbure \u00e0 cha\u00eene courte, bien qu'il ait une tension superficielle plus faible, il peut rendre la r\u00e9sistance du film de surface form\u00e9 tr\u00e8s faible, et peut donc favoriser la rupture des bulles, de mani\u00e8re \u00e0 atteindre efficacement l'objectif de l'\u00e9limination des bulles.<\/p>\n\r\n\t\t<\/div>\r\n\t<\/div>\r\n<\/div><\/div><\/div><\/div><div class=\"vc_row-full-width vc_clearfix\"><\/div><section
