In the process of industrial cleaning of metal molds, the foam produced by water-based cleaning agents is affected by many factors, such as the amount of oil stains, cleaning agent selection, water hardness, and cleaning conditions. If the foam is not controlled in time, it may interfere with the cleaning process, affecting the cleaning progress and mold cleanliness. Therefore, using metal grinding tool cleaning defoaming agent is an ideal choice to eliminate foam.
(Metal mold cleaning agent defoamer: have a higher quality cleaning process!)
The oil stain reacts with the alkali saponification in the cleaning solution to form fatty acid soap, causing the cleaning solution to foam. However, surfactants are the main contributor to foaming in water-based cleaners. Excess surfactant will reduce the surface tension of the liquid and may surround the bubbles in the liquid and form a stable double-layer protective film.
Other ingredients in metal mold cleaning agents, such as acids, alkalis and electrolytes, will also affect the foaming degree and foam stability of the cleaning solution. In addition, external conditions such as cleaning agent concentration, cleaning temperature, and cleaning methods will also affect the degree of foam generation. Therefore, in order to achieve ideal cleaning results, different cleaning agents need to be prepared according to cleaning conditions. When formulating a cleaning agent, consider its foaming properties.
Defoaming agents are mainly divided into two categories: antifoaming agents and defoaming agents. Foam suppressors suppress the formation of foam, while defoaming agents eliminate foam that has already been produced. According to different ingredients, defoaming agents can be divided into silicone defoaming agents, polymer defoaming agents, mineral oil defoaming agents, etc.
Metal mold cleaning agent defoamer is a silicone foam suppressor specially designed for water-based metal processing system concentrates, which can make the water-based emulsion very stable. This defoaming agent has a wide application range, low dosage, and fast defoaming. It can not only quickly eliminate foam, but also has more significant performance in foam suppression and durability. Under different acid and alkali conditions (pH value is 4~12), the defoaming agent can still exert anti-foaming and defoaming effects.
