Description

technical field

[0001] The invention relates to a preparation method of an industrial defoamer. The prepared defoamer is suitable for defoaming and foam suppression in papermaking, printing and dyeing, fermentation and sugar production processes. Background technique

[0002] In the process of papermaking, printing and dyeing, fermentation and sugar refining, a large amount of foam is often produced, which affects the smooth progress of the process. In order to ensure production, it is necessary to use defoamers to eliminate or reduce foam.

[0003] At present, there are many kinds of defoamers, mainly oils, polyethers, polysiloxanes and sulfonated oils. However, the application of these defoamers has certain limitations, and there are disadvantages such as complex production process, high price, or inconvenient use, especially in papermaking, sugar and other industries. Contents of the invention

[0004] The purpose of the present invention is to provide a kind of prepar...
