How to Use Powder Defoamer?
Powder defoamer is made of polysiloxane, special emulsifier and highly active polyether defoamer polymerized by special process for cement and gypsum-based dry-mix mortar mix. It has the characteristics of strong defoaming ability, low dosage, long-lasting foam inhibition, good thermal stability, good fluidity, no side effects and convenient transportation. It has strong defoaming and foam inhibition performance in high temperature and high alkalinity solution.
Powder defoamers are typically used in industrial settings to prevent the formation of foam in liquids. The specific method of use will depend on the type of powder defoamer and the application it is being used in.
1. First, determine the appropriate amount of powder defoamer to use. This will typically be specified by the manufacturer and can be determined by performing a trial run or by consulting with a technical representative.
2. Next, add the powder defoamer to the liquid that requires de-foaming. This can be done by hand or by using a metering device such as a screw feeder or a vibratory feeder.
3. Mix the powder defoamer into the liquid thoroughly. This can be done by hand, using a mechanical mixer, or by circulating the liquid through a piping system. The goal is to ensure that the powder defoamer is evenly distributed throughout the liquid.
4. Monitor the liquid for foam formation. If foam is still present, adjust the amount of powder defoamer or the mixing method as needed. It's important to note that the effectiveness of the defoamer may vary depending on the application and the type of foam being produced.
5. If using a defoamer in a closed system, it is recommended to use a continuous feed system. This ensures that the defoamer is continuously added to the system and that the foam is suppressed.
6. It is also important to note that some powder defoamers may not be compatible with certain types of liquids or with other chemicals that are present in the liquid. Always check with the defoamer manufacturer or a technical representative to ensure compatibility before using a powder defoamer.
7. In some cases, it is also recommended to use defoamers in combination with other anti-foaming agents such as liquid defoamers or mechanical methods like skimming to achieve optimal results.
8. It's also important to handle the powder defoamer carefully, as it may be harmful if inhaled or ingested. Always follow the manufacturer's safety guidelines when handling the powder defoamer.
9. Proper storage of powder defoamers is important to ensure the product's effectiveness and shelf life. Store in a dry and cool place and away from direct sunlight.
In summary, the use of powder defoamers involves adding the appropriate amount of powder to the liquid, mixing it thoroughly, monitoring for foam formation, and adjusting as needed. It's important to ensure compatibility with the liquid and other chemicals present, as well as proper handling and storage.
