Le silicone modifi\u00e9 au poly\u00e9ther est un copolym\u00e8re poly\u00e9ther-siloxane (copolym\u00e8re siloxane-\u00e9ther en abr\u00e9g\u00e9) pr\u00e9par\u00e9 en introduisant des segments poly\u00e9ther dans la mol\u00e9cule de siloxane.

Il est fabriqu\u00e9 \u00e0 partir de poly\u00e9ther avec une forte capacit\u00e9 anti-moussante et d'huile de silicone dim\u00e9thylique \u00e0 forte hydrophobie et rupture rapide de la mousse comme composants principaux, en associant l'\u00e9mulsifiant, le stabilisant et d'autres composants permettant de combiner organiquement l'huile de silicone avec le poly\u00e9ther. <\/span><\/span><\/span><\/span><\/span><\/span><\/span>S<\/span><\/span><\/span><\/span><\/span><\/span><\/span><\/span>agent antimousse silicone<\/span><\/span><\/span><\/span><\/span><\/span><\/span>, c<\/span><\/span><\/span><\/span><\/span><\/span><\/span><\/span>et agent antimousse silicone<\/span><\/span><\/span><\/span><\/span><\/span><\/span>e<\/span><\/span><\/span><\/span><\/span><\/span><\/span><\/span>\u00a0poss\u00e8de les caract\u00e9ristiques de <\/span><\/span><\/span><\/span><\/span><\/span><\/span>faible tension superficielle, d\u00e9fomage rapide, temps de suppression prolong\u00e9, faible co\u00fbt, faible dosage et large gamme d'application<\/span><\/span><\/span><\/span><\/span><\/span><\/span><\/b>.

Dans la mol\u00e9cule de copolym\u00e8re siloxane-\u00e9ther, le segment siloxane est un groupe lipophile, et le segment poly\u00e9ther est un groupe hydrophile. Dans le segment poly\u00e9ther, la cha\u00eene d'oxyde de poly\u00e9thyl\u00e8ne \u00e9conomise l'\u00e9nergie pour fournir l'hydrophilie et la moussabilit\u00e9, et la cha\u00eene d'oxyde de polypropyl\u00e8ne \u00e9conomise l'\u00e9nergie pour fournir l'hydrophobie et la perm\u00e9abilit\u00e9, ayant un fort effet sur la r\u00e9duction de la tension superficielle. Les groupes en extr\u00e9mit\u00e9 de cha\u00eene poly\u00e9ther ont \u00e9galement une grande influence sur les propri\u00e9t\u00e9s du copolym\u00e8re siloxane-\u00e9ther. Les groupes terminaux courants sont l'hydroxyle, l'alcoxy, etc. L'ajustement de la masse mol\u00e9culaire relative du segment siloxane dans le copolym\u00e8re peut faire ressortir ou att\u00e9nuer les caract\u00e9ristiques du silicone. De m\u00eame, la modification de la masse mol\u00e9culaire relative du segment poly\u00e9ther augmentera ou diminuera la proportion de silicone organique dans la mol\u00e9cule, affectant les performances du copolym\u00e8re.

Au-dessus de sa temp\u00e9rature de trouble, il perd sa solubilit\u00e9 dans l'eau et sa stabilit\u00e9 m\u00e9canique, et r\u00e9siste aux acides, aux bases et aux sels inorganiques, pouvant \u00eatre utilis\u00e9 pour le d\u00e9moussage dans des conditions s\u00e9v\u00e8res.<\/span><\/span><\/span><\/span><\/span><\/span><\/span><\/span><\/span><\/span><\/p>\n

Afin d'am\u00e9liorer la lipophilie des encres aqueuses, des rev\u00eatements, des fluides de coupe, etc., une partie des groupes m\u00e9thyle dans les mol\u00e9cules du copolym\u00e8re du silicone modifi\u00e9 au poly\u00e9ther <\/span><\/span><\/span><\/span><\/span><\/span><\/span>d\u00e9froisseur en silicone<\/span><\/span><\/span><\/span><\/span><\/span><\/span>\u00a0est remplac\u00e9e par des groupes alkyle \u00e0 longue cha\u00eene, ce qui peut exercer plus efficacement l'effet antimousse. Afin d'avoir de meilleures performances antimousses en dessous de la temp\u00e9rature de trouble, les antimousses auto-\u00e9mulsifiants commerciaux sont g\u00e9n\u00e9ralement \u00e9quip\u00e9s d'une p\u00e2te d'huile de silicone dim\u00e9thylique - noir de carbone blanc, moment auquel, sous la temp\u00e9rature de trouble, les surfactants modifi\u00e9s au poly\u00e9ther-silicone peuvent \u00e9galement \u00eatre utilis\u00e9s comme \u00e9mulsifiants pour l'huile de silicone dim\u00e9thylique pour jouer un r\u00f4le de dispersion et d'\u00e9mulsification.<\/span><\/span><\/span><\/span><\/span><\/span><\/span><\/span><\/span><\/span><\/p>\n
