Defoamer, also known as antifoaming agent, is an industrial additive that eliminates foam and can reduce and prevent the appearance of foam in industrial production liquids. The appearance of foam is suppressed by its anti-foam properties.
In industrial production, it is often encountered that the appearance of foam affects the performance parameters of the product. Therefore, it is necessary to have the help of a defoamer. It has a high affinity with the air and liquid surface, which will make the foam unstable and cause the foam to burst.
According to chemical composition, defoamer can be divided into silicone, polyether, mineral oil, alcohol and other types, with faster defoaming speed, longer defoaming time, wider range of applicable media and high temperature, strong acid , strong alkali and other harsh medium environments can be applied to the characteristics.
Where can defoamers be used?
1. Food manufacturing
When used as a food additive,it is mainly used to inhibit the foam in the process of food production and consumption.As far as the current situation of food is concerned,edible defoamer has become a preparation material for many kinds of food.
Take the production of tofu as an example,because a lot of foam will appear during the production process.In order to prevent the foam from overflowing and the production of harmful substances,manufacturers list edible defoamer as an ingredient in foods such as tofu.
2. Industrial use
In many industrial production and products, defoamer can be used in papermaking,paint,ink,sewage treatment,oil field drilling,metal processing,adhesives,power plant desulfurization.such as building material defoamer,oil-based defoamer,water treatment defoamer.
3.Medicinal use
Defoamer can also be used in medicine and medicine. In terms of pharmaceuticals,it mainly acts on the matrix of solvent ointments and the defoaming of extracts,oral liquids and injections.It is also directly used in preparations,such as simethicone tablets whose main function is to relieve abdominal distension.It is a drug for gastrointestinal diseases.It is mainly used to treat the uncomfortable symptoms caused by excessive gas accumulation in the gastrointestinal tract.
