Development overview of water-based defoaming agents
Rapid realization of defoaming is one of the most basic properties of water-based defoaming agents, but whether it can suppress the generation of foam for a long time is the main indicator of judging the quality of water-based defoaming agents. Because in many cases, we add water-based defoaming agent at the beginning of the operation to use its anti-foaming performance to suppress the generation of foam. We do not wait until a large amount of foam is generated before adding water-based defoaming agent for defoaming.
However, the defoaming and foam-suppressing properties of defoaming agents are relative. A water-based defoamer with good defoaming properties will have relatively poor foam-suppressing properties. A water-based defoaming agent with good foam-suppressing properties will have poor defoaming properties. It will be relatively worse. In actual applications, it depends on the specific situation.
Water-based defoaming agents can be divided into two categories: silicon-containing and non-silicon-containing. Since most of the raw materials for silicon-containing water-based defoaming agents are imported from abroad and are limited by production technology, the quality of the products produced is also very different from that of foreign countries. gap, so due to limitations of raw materials, the development of silicon-containing water-based defoaming agents is relatively slow. However, the development of silicon-free water-based defoaming agents is relatively fast, because the raw materials and manufacturing process are relatively simple and the cost is low, which provides great convenience for the development of non-silicon water-based defoaming agents.
However, if you want to improve the performance of water-based defoaming agents and develop water-based defoaming agents with more diverse properties, you need to pay attention to the compounding of water-based defoaming agents, the mechanism of water-based defoaming agents, and the technology to improve water-based defoaming agents. In the defoaming agent industry, Shanghai Boyihe Chemical has continuously updated its water-based defoaming agent products after years of precipitation and accumulation. The water-based defoaming agent developed has many excellent features: good dispersion, rapid defoaming, It is environmentally friendly, has a mild smell, and will not cause harm to production. It can be widely used in the production processes of antifreeze, distillation systems, textile printing and dyeing, water-based coatings, petrochemicals, paper industry, and many other industries to quickly eliminate harmful foam without causing pollution to the environment.
