How to judge the defoamer is the most suitable foam control solutions in landfill leachate? 1. Defoamer should be tested and verified the added volume by small trial test. 2. The amount and the method of addition depends on the foaming capacity of the water on site. Moreover, the wastewater treatment should be a dynamic process of continuous replenishment of new wastewater. 3. The foami...
During high temperature textile dyeing, there are excessive foam problem in many textile mills. In order to get the most suitable defoamer and competitive defoamers, the material and range temperature is necessary! Under the polyester material, the temperature is above 130℃， Please kindly find the typical defoamer RK-83S.
In fermentation industry, including molasses fermentation, alcoholic fermentation, yeast or amino acid production, and other processes, no matter what type material, the excessive foam affect the efficiency and quality of production. Generally , silicone and polyether defoamers provide high efficiently antifoaming performance in fermentation. How to find a suitable defoamer solution in fermentatio...
Conversion processes from bauxite to alumina in a Bayer process undergo in a highly alkaline environment. Such extreme pH levels required specific chemistry to be able to function well in a Bayer process. Whether it's for faster red mud settling in the settlers & washers, higher solid content in classifying thickener underflow, or protecting your digester from corrosion during acid cleaning, a...
Antifoam is a chemical compound used to reduce foam in papermaking white water. It is typically added to the wet end of the papermaking process, where it helps to prevent foam from forming and interfering with the production process. According to the different requirements and conditions, fatty alcohol antifoams and polyether defoamers are most acceptable in paper mills. They have their own ...
Introduction: With the development of modern science and technology, the uses of paper is becoming increasingly broad, some of which require the application and processing under the action of water. Such as marime tharl paper, special map paper, currency paper, advertising poster paper, absorbent cotton paper, tablecloth paper, industrial filter paper, photographic base paper, tea filter...
Harm of foaming: Foam in water-reducing admixtures/ concrete admixture can cause a number of problems. Foam can reduce the effectiveness of the admixture, leading to reduced performance in concrete. It can also cause air entrainment, which can lead to increased permeability and decreased strength. Additionally, foam can reduce the flowability of the admixture, making it difficult to mix and a...
Harm of foam: Foam in cement mortar can reduce the strength of the mortar, reduce its water-resistance, and increase its permeability. This can lead to structural damage over time due to water infiltration, which can cause cracking and spalling of the mortar. Foam also reduces the bond between the cement and aggregate, resulting in a weaker mortar. In addition, foam can trap air bubbles in the mor...
