Preparation method of particle defoaming agent

Abstract

The invention provides a preparation method of particle defoaming agent characterized in that organic silicon emulsion is used to substitute silicone grease and agglomerated on carrier by substeps to form two silicone grease layers to overcome overlarge concentration gradient and non-uniform distribution of active matter generated by one-step agglomeration, thus the external and internal of the defoaming agent particle both have sufficient defoaming components to act a slow-release function in order to improve the defoaming, foaming inhibition and stable performance of the product. The solid particle defoaming agent prepared has excellent defoaming and foaming inhibition effects in the cleaning of various heat exchange devices, boilers, heat exchange pipes and in the cleaning process of steal plate, machinery, cement, starch pasting and washing powder.

Description

technical field

[0001] The invention relates to a method for preparing a granular defoamer. The defoamer belongs to the additive of fine chemicals, therefore, the present invention belongs to the technical field of fine chemicals. technical background

[0002] In industrial cleaning, industrial cleaning agents are needed to remove dirt and reduce the surface tension between oil and water. The cleaning agent contains a large amount of surfactant. During the agitation process, the surfactant will be adsorbed around the bubbles to stabilize the bubbles, thereby generating a large amount of foam. This situation is more prominent in beer bottle cleaning, cleaning of various heat exchange equipment, boilers, heat exchange pipes, steel plate cleaning, mechanical cleaning, cement, starch gelatinization and other industrial processes. The existence of foam will reduce production capacity, cause waste of raw materials and products, prolong the reaction cycle, affect product quality,...
