In the process of industrial cleaning of metal molds, the foam generated by water-based cleaning agents is affected by many factors, such as the amount of oil, the choice of cleaning agent, the hardness of water quality and the cleaning conditions. If the foam is not controlled in time, it may interfere with the cleaning process, affecting the cleaning progress and the cleanliness of the mold. Therefore, the use of metal mold cleaning agent defoamer is an ideal choice to eliminate foam.
(Metal mold cleaning agent defoamer: have a higher quality cleaning process!)
The oil and alkali in the cleaning liquid saponify to form fatty acid soaps, which cause the cleaning liquid to foam. However, surfactants are the main factor in the generation of foam in water-based cleaning agents. Excess surfactants 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 additives such as acids, alkalis and electrolytes, will also affect the foaming degree and foam stability of the cleaning liquid. In addition, external conditions such as cleaning agent concentration, cleaning temperature, and cleaning method will also affect the degree of foam generation. Therefore, in order to achieve the ideal cleaning effect, different cleaning agents need to be prepared according to the cleaning conditions. When preparing cleaning agents, their foaming properties need to be considered.
Defoamers are mainly divided into two categories: defoamers and antifoamers. Defoamers can inhibit the generation of foam, while defoamers can eliminate the generated foam. According to different ingredients, defoamers can be divided into silicone defoamers, polymer defoamers, mineral oil defoamers, etc.
Metal mold cleaning agent defoamer is a silicone defoamer designed for water-based metal processing system concentrates, which can make the water-based emulsion very stable. This defoamer has a wide range of applications, low dosage, and fast defoaming. It can not only quickly eliminate foam, but also has more significant performance in terms of foam suppression and durability. Under different acid and alkali conditions (pH value is 4~12), this defoamer can still play a role in defoaming and defoaming.
