Paper water treatment defoaming agent is mainly used in pulp and paper production from the paper industry. The main components in this process are lignin, cellulose, volatile organic acid, etc., with ......
2020-01-13Oil-containing wastewater treatment defoaming agent is mainly used in the oil industry, iron and steel, gas workstations, mechanical industry cooling lubricants, etc., the oil cover in the wastewater ......
2020-01-13The composition of dye wastewater is complex and the color is deep, which causes serious pollution to the environment. Cationic dye wastewater is difficult to biodegrade and decolorize due to its comp......
2020-01-13As petrochemical, plastics and other industrial development, more and more factories discharge waste water containing aromatic compounds, this kind of wastewater pollutants stable structure, refractor......
2020-01-13Silicone oil with larger molecular weight is insoluble in surfactant solution, while for small molecules, silicone oil is easily solubilized by surfactant molecules, which changes the composition of d......
2020-01-13In the production process of coating, air will be drawn in to form bubbles. Some raw materials such as surfactant and dispersant will make bubbles stable. &nbs......
2020-01-10Defoamer plays a role in the formation or after the formation of thin foam. Dispersing uniform defoamer permeates into the foam elas......
2020-01-10Defoamer must be able to spread quickly on the foam surface and permeate quickly, so that the foam will burst quickly. At present, the commonly used defoamers are organosilicon and polyacrylate. ......
2020-01-10In recent years, with the development of building an environment-friendly society and the improvement of people's living standards, the consumption of various packaging materials has increased signifi......
2020-01-101. Adding this method before foaming can inhibit the production of foam by adding defoaming agent in the system that may produce foam in advance. For closed container and device, defoaming agent can e......
2020-01-10Defoamer does not exist in the system in the dissolved state, but is generally suspended in the system. Therefore, the amount and color of hydrophobic particles, silicone oil and hydrophobic particles......
2020-01-09The property of silicone oil in defoamer determines the antifoaming time of defoamer. The amount of silicone oil determines the use time of defoamer in the system. The particle size of defoamer determ......
2020-01-09The problem of acid-base stability, if the acid and alkali resistance of defoaming is not good, causes the decomposition of silicone oil, resulting in the failure of defoamer. Some chemical components......
2020-01-09Defoamer is mainly used to reduce the surface tension and eliminate foam during processing. Most of the bubbles are produced by external forces. The surface active substances in the solution are forme......
2020-01-09Defoamers can be roughly divided into two categories: one is able to eliminate the generated bubbles, such as ethanol; the other is able to inhibit the formation of bubbles, such as emulsified silicon......
