Learn about the hazards of defoamers
1. The production volume of defoaming agents is subject to many limitations: such as various fermentation tanks and reaction tanks in various biological fermentations (wine production, ethanol production, production of major antibiotics in the pharmaceutical industry…) For canning and other equipment, in order to prevent the occurrence of foam and avoid overflow damage, the filling index will be greatly affected, sometimes not reaching 40%.
2. Defoaming agents lead to extravagant waste of raw materials and goods: Because of foam plastics, effective or precious raw materials can be damaged due to overflow, and the extravagant waste caused is obvious. For example, the filling process of textile factories and sugar factories, and the oiling process of the weaving process of knitting factories often cause overflow due to foam.
3. The defoaming agent increases the reaction cycle: Because the exothermic reaction material contains gas and liquid, the foam will cause the gas to stay, which increases the reaction cycle and wastes more power. And if the wine ferments and becomes sour due to excessive reaction due to the presence of foam…
4. Affect product quality: During the process of dyeing, printing and water-based paint in cotton textiles, due to the retention of air bubbles, marks and defects will be caused on the finished cloth; in addition to the foam of pulp slurry, Hygiene and employee health are seriously affected, and many holes will appear in the finished paper, resulting in a serious reduction in product quality.
5. Defoamer is not conducive to measurement and verification: During the industrial production process, due to the presence of foam, it interferes with the measurement accuracy of the liquid level meter, resulting in measurement errors. The presence of foam in the liquid increases the density of the liquid. Large fluctuations occur, which can also cause false alarms in the liquid level of the reaction tank, desulfurization tower, distillation tower, causing the operation to become unbalanced, and even cause safety accidents.
6. The first cause of environmental pollution and accidents: due to the overflow of foam plastics, it will inevitably pollute the environment and the surrounding environment, and some may even lead to major accidents. For example: a chemical plant in the United States caused a major fire accident due to the overflow of residual oil foam, resulting in heavy casualties. This not only caused extravagance and waste, but also caused huge losses to people’s personal safety.
In addition, there are also the application of new technologies such as high-temperature spray dyeing and overflow dyeing on defoaming agents. If the problem of foam is not solved, it cannot be maintained. Another example is the automatic washing machine that is now very popular. If it does not solve the problem of no foaming and low foaming of soap powder and detergent, then the automatic washing machine cannot be so widely used. This is far from all the damage caused by foam, but its serious consequences can be seen.
