\n\t\t\t\t\t\t\t\t\tLes bulles peuvent sembler un probl\u00e8me mineur dans les projets de construction, mais elles peuvent s\u00e9rieusement affecter la qualit\u00e9 de la construction. Les bulles d'air cr\u00e9\u00e9es pendant le m\u00e9lange du b\u00e9ton peuvent r\u00e9duire la r\u00e9sistance finale. Des r\u00e9sultats exp\u00e9rimentaux ont conclu qu'un exc\u00e8s de bulles d'air peut entra\u00eener une r\u00e9duction de 10 \u00e0 15 % de la r\u00e9sistance \u00e0 la compression du b\u00e9ton. Les bulles d'air dans les rev\u00eatements ou les mat\u00e9riaux d'imperm\u00e9abilisation peuvent provoquer des trous d'\u00e9pingle \u00e0 la surface du rev\u00eatement, ce qui affecte les performances d'imperm\u00e9abilisation. La pr\u00e9sence de bulles dans le mortier r\u00e9duit la compacit\u00e9 et entra\u00eene un risque de fissuration. En tant que professionnel\u00a0fabricant d'antimousse en poudre<\/a>Nous pouvons vous aider \u00e0 r\u00e9soudre ces probl\u00e8mes.\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

I. Qu'est-ce qu'un antimousse en poudre ?<\/h2>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t
\n\t\t\t\t
\n\t\t\t\t\t\t\t\t\tL'antimousse en poudre est un antimousse solide \u00e0 base de poly\u00e9ther modifi\u00e9, particuli\u00e8rement adapt\u00e9 pour\u00a0mat\u00e9riaux m\u00e9lang\u00e9s \u00e0 sec<\/a>. La fonction principale est d'\u00e9liminer rapidement la mousse existante et d'emp\u00eacher la formation de nouvelle mousse, c'est-\u00e0-dire la fonction de d\u00e9moussage et d'inhibition de la mousse.\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

\n\t\t\t\t\t\t\t\t\t

Les antimousses en poudre sont g\u00e9n\u00e9ralement constitu\u00e9s de mat\u00e9riaux \u00e0 base de silicone, de poly\u00e9ther ou d'huile min\u00e9rale, transform\u00e9s en particules de taille microm\u00e9trique par des techniques sp\u00e9ciales. Leur principe de base est de rendre la paroi de la mousse plus fine et de la faire \u00e9clater en r\u00e9duisant la tension superficielle du liquide.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

\n\t\t\t\t\t\t\t\t\t

L'antimousse en poudre a une meilleure stabilit\u00e9 de stockage et est facile \u00e0 transporter. Plus facile \u00e0 manipuler dans la production de m\u00e9langes secs, il peut \u00eatre directement m\u00e9lang\u00e9 aux mat\u00e9riaux de m\u00e9lange secs (ciment, poudre de gypse) de mani\u00e8re uniforme et n'affecte pas la fluidit\u00e9.<\/p>

L'antimousse liquide est plus facile \u00e0 disperser dans un syst\u00e8me aqueux, il doit \u00eatre antigel et anti-d\u00e9cantation.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

\n\t\t\t\t
\n\t\t\t\t\t\t\t\t\tL'antimousse en poudre que vous choisissez doit \u00eatre compatible avec votre formulation. Choisissez un antimousse qui n'interf\u00e8re pas avec la r\u00e9action d'hydratation du ciment. Par exemple, dans\u00a0colles \u00e0 carreaux<\/a>\u00a0contenant\u00a0HPMC<\/a>\u00a0et\u00a0poudre de polym\u00e8re redispersable<\/a>Des antimousses incompatibles peuvent r\u00e9duire l'ouvrabilit\u00e9 ou causer des probl\u00e8mes de s\u00e9paration.\n
\n
\nConseil :<\/b> Toujours tester la compatibilit\u00e9 des formulations d'application, en particulier si des formulations complexes sont utilis\u00e9es.\n
\n
\nM\u00e9thode d'essai :<\/b> Ajouter l'antimousse au mat\u00e9riau \u00e0 un taux de 0,1%-0,3% et observer la compatibilit\u00e9 et l'effet antimousse.\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

\n\t\t\t\t
\n\t\t\t\t\t\t\t\t\tSelon la norme ASTM D892, un antimousse en poudre de bonne qualit\u00e9 doit \u00e9liminer plus de 90% de bulles d'air en 5 minutes. Un bon antimousse doit non seulement briser les bulles, mais aussi emp\u00eacher leur r\u00e9apparition :\n
\n\u00c9limine rapidement les bulles d'air en surface pendant le m\u00e9lange.\n

Des syst\u00e8mes diff\u00e9rents ont des besoins diff\u00e9rents, et un antimousse qui fonctionne bien dans les mortiers \u00e0 base de ciment peut ne pas convenir aux applications \u00e0 base de gypse.

Un client d'Asie du Sud-Est qui fabrique du mastic modifi\u00e9 par des polym\u00e8res rencontrait des probl\u00e8mes de bulles et de piq\u00fbres dans ses murs apr\u00e8s le s\u00e9chage. L'antimousse qu'il utilisait auparavant se dispersait mal et donnait des r\u00e9sultats irr\u00e9guliers.<\/p>

Apr\u00e8s avoir test\u00e9 notre antimousse en poudre TENESSY\u00ae, les r\u00e9sultats ont \u00e9t\u00e9 \u00e9vidents :<\/p>

R\u00e9duction de l'air emprisonn\u00e9 de plus de 60%.<\/p>

Am\u00e9lioration du lissage et de la finition de la surface.<\/p>

Dosage plus faible (0,3% contre 0,6% auparavant).<\/p>

Pas d'effet sur l'ouvrabilit\u00e9 ou le temps de prise.<\/p>

Ils permettent non seulement d'am\u00e9liorer la qualit\u00e9 des produits, mais aussi de r\u00e9duire les co\u00fbts de production.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t
