Abstract

The invention discloses a defoaming agent. The defoaming agent comprises the following raw materials in parts by weight: 30-40 parts of dimethyl silicon oil, 3-5 parts of potassium iodide, 5-10 parts of polyether, 3-5 parts of paraffin, 6-10 parts of an emulsifier, 3-5 parts of ethylene glycol, 1-2 parts of stearic acid and 5-10 parts of tributyl phosphate. The defoaming agent disclosed by the invention has the advantages of high defoaming speed, good inhibition performance and no influence on basic nature of a foaming system, as well as good diffusibility and permeability.

Description

technical field [0001] The invention relates to a defoamer, which belongs to the technical field of chemical industry. Background technique [0002] Antifoaming agent, also known as antifoaming agent, is a food additive that reduces surface tension during food processing, inhibits foam generation or eliminates foam that has already occurred. There are many types of existing defoamers, some will affect the basic properties of the foaming system, some have poor defoaming effect, poor suppression performance, some are not good enough in diffusivity, and some are chemically unstable and safe The performance is not high. Contents of the invention [0003] Purpose of the invention: The purpose of the invention is to provide a defoamer with fast defoaming, good suppression performance, and good diffusivity and permeability. [0004] Technical solution: a defoamer according to the present invention is characterized in that it includes the following raw materials in proportion by...
