Efficient Defoaming: AFE-7620 Defoamer can quickly eliminate a large amount of foam generated during processes such as papermaking pulping, sewage treatment, papermaking, metal cleaning, and cutting fluid processing. In the papermaking pulping process, adding a small amount of this defoamer can rapidly reduce the foam height within 3-5 minutes, with a defoaming rate of over 95%. This effectively avoids paper quality issues caused by excessive foam, such as holes and spots.
Long-lasting Foam Suppression: It has excellent long-lasting foam suppression performance. With a single addition, it can continuously inhibit foam regeneration for 8-10 hours during the continuous production process of papermaking pulping, reducing the trouble and cost of frequent defoamer addition. In the sewage treatment process, it can also maintain foam at a low level for a long time, ensuring the normal operation of sewage treatment equipment.
Strong Chemical Stability: AFE-7620 Defoamer exhibits good stability in different chemical environments. In the metal cleaning process, even if the cleaning solution contains chemicals such as acids and alkalis, it will not react with the cleaning solution, nor will it affect the cleaning effect. At the same time, its own defoaming performance will not be significantly affected.
Good Dispersibility: This defoamer can quickly and evenly disperse in the system. During the cutting fluid processing process, it can rapidly disperse into the entire cutting fluid system and quickly exert defoaming and foam-suppressing effects, avoiding the situation where foam is eliminated locally while remaining severe in other parts.
Application Fields
Papermaking Industry: Suitable for the papermaking pulping stage to eliminate foam generated during the stirring and transportation of pulp, ensuring the forming quality of paper. It can also be used in processes such as coating and sizing during papermaking to prevent foam from affecting the appearance and performance of paper.
Sewage Treatment: In sewage aeration, sludge treatment and other links, it can effectively eliminate foam generated by microbial activities, surfactants, etc., ensuring the stable operation of sewage treatment equipment and avoiding environmental pollution problems caused by foam overflow.
Metal Cleaning: Used in the cleaning process of metal parts to eliminate foam caused by cleaning agents, oil stains, etc., making the cleaning process smoother and improving cleaning efficiency and quality.
Cutting Fluid Processing: It can effectively control foam generated in the cutting fluid during processing due to mechanical stirring, high-speed cutting, etc., ensuring the normal exertion of the cooling, lubricating and other properties of the cutting fluid and extending the service life of cutting tools.
Precautions
During storage, it should be placed in a cool and dry place, avoiding direct sunlight and high temperatures. The recommended storage temperature is between 0-30℃ to ensure the stable performance of the product.
When in use, the addition amount should be adjusted reasonably according to different application scenarios and foam conditions. Excessive addition may have a certain impact on the subsequent processes of some systems.
During handling and use, care should be taken to prevent the product from coming into contact with the skin and eyes. In case of accidental contact, rinse immediately with a large amount of water and seek medical attention in a timely manner.
