    • A process for making a foam control composition comprising a cross-linked polyorganosiloxane in which is dispersed a filler, with hydrophobic surface, comprising step (A) mixing (i) a finely divided filler, (ii) a polyorganosiloxane having on at least two reactive substituents, for example on average two reactive substituents, and (iii) a polyorganosiloxane having at least three reactive substituents, capable of addition reaction via hydrosilylation; (B) hydrosilylation reaction of components (ii) and (iii) until the mixture at least partially gels, followed by applying shearing forces to this at least partially gelled mixture. Optionally step (A) comprises a diluent or solvent and after step (B) an emulsification step is carried out to make the foam control composition into an O/W emulsion. Also a process for controlling foam in an aqueous environment by using a foam control composition according to the invention, selected from inks, coatings, paints, detergents, black liquor of from those encountered during pulp and paper manufacture, waste water treatment, textile dyeing processes or the scrubbing of natural gas.
    • 一种制备泡沫控制组合物的方法,其包含交联的聚有机硅氧烷,其中分散有疏水表面的填料,所述方法包括步骤(A)将(i)细碎填料,(ii)至少两个反应性的聚有机硅氧烷 取代基,例如平均两个反应性取代基,和(iii)具有至少三个反应性取代基的聚有机硅氧烷,能够通过氢化硅烷化进行加成反应; (B)组分(ii)和(iii)的氢化硅烷化反应,直到混合物至少部分凝胶化,然后对该至少部分胶凝的混合物施加剪切力。 任选地,步骤(A)包括稀释剂或溶剂,并且在步骤(B)之后,进行乳化步骤以使泡沫控制组合物成为O / W乳液。 还有一种通过使用根据本发明的泡沫控制组合物来控制泡沫的方法,该组合物选自油墨,涂料,油漆,洗涤剂,在纸浆和造纸过程中遇到的黑液,废水处理,纺织染色方法 或擦洗天然气。
