Solid particle foam inhibitor and method for preparing same

Abstract

The invention relates to a solid particle foam inhibitor and a method for preparing the same. The ingredients of the foam inhibitor consist of 50-80% of organic carrier, 10-18% of main defoaming materials, 0.5-4% of emulsifying agent, 1-10% of structural agent and 3-25% of deionized water. The method for preparing the foam inhibitor comprises the following steps of: sufficiently mixing the main defoaming materials with the emulsifying agent; adsorbing the main defoaming materials and the emulsifying agent on the carrier; and adding the structural agent and forming particles with good liquidity through working procedures of granulating and drying. The prepared solid particle foam inhibitor has excellent applications in industrial processes, such as washing, sewage treatment and textile printing and dyeing.

Description

technical field

[0001] The invention relates to a solid particle antifoam agent and a preparation method thereof. The invention uses solid powder attached to polysiloxane to prepare a novel solid particle antifoam agent. This type of solid particle antifoam agent can be used in cleaning, daily chemical, Used in sewage treatment, textile printing and dyeing and other industries. Solid particle foam suppressor belongs to fine chemical additives. Therefore, the present invention belongs to the technical field of fine chemical preparations. technical background

[0002] Foam is a common phenomenon in industrial processes such as industrial cleaning, sewage treatment, textile printing and dyeing, cement application, starch gelatinization, etc. Different systems have different reasons for foaming. For example, in industrial cleaning, industrial cleaning agents are used to remove dirt. Since the cleaning agent contains a large amount of surfactant, during the agitation process, t...
