High-temperature defoamer is a special chemical additive that is mainly used to eliminate and inhibit foam generation in high-temperature environments. Here are some common types of high-temperature defoamers: DefoamersFatty alcohols: Fatty alcohol-based high-temperature defoamers can be stably defoamed at strong alkalis and high temperatures, and can quickly penetrate into the liquid and spread rapidly.
Amides: Amide defoamers are also a type of high-temperature resistant defoamer, which are polymerized through a special process and can work effectively in high-temperature environments.
Polyethers: Polyether defoamers are known for their strong foam inhibition ability, and some polyether defoamers also have the properties of high temperature resistance, strong acid and alkali resistance.
Hydrocarbons: Hydrocarbon defoamers can also be prepared into high-temperature resistant types by special processes, which are suitable for defoaming under extreme conditions.
Silicone oils: Silicone oil defoamer also has good high temperature resistance, which can maintain the defoaming effect at higher temperatures.
Fluorocarbons: Fluorocarbon defoamers have excellent high temperature resistance and can maintain stable defoaming effect in extreme high temperature environments.
It should be noted that when selecting a high-temperature defoamer, specific application scenarios and requirements, such as temperature conditions, acid-alkali environment, type of foam, etc., should be considered to ensure that the selected defoamer can meet the specific industrial needs.
