Glue defoamer, a good helper for the adhesive industry
From the perspective of life and industrial production, the basic properties and uses of glue can be really a lot, such as glue can be used for the bonding of structural parts, manufacturing aircraft with can reduce the structural mass of the aircraft, increase the speed; with high temperature and low temperature resistance, can be hot melt, pressure sensitive, oil surface bonding use, etc.. In the production process of glue, in order to meet these excellent performance needs, often to many details to achieve strict control, adding glue defoamer for foam suppression is one of them.
So, the phenomenon of glue blistering is how it is, what is the role of adding glue defoamer? These questions are actually not complicated, today we will come together to learn more about it.
1. Why does the glue blister?
Due to the process, glue needs to add abundant surfactants in the production process, which tend to reduce the surface tension of the solution, thus creating bubbles floating on the liquid surface. Besides, the temperature, humidity, uneven distribution of the ratio in the process of glue mixing and the external forces such as stirring are also the reasons for the generation of bubbles.
2.What is the role of adding glue defoamer?
Adhesive defoamer is a kind of reagent with excellent defoaming and foam inhibiting power specially developed for adhesive industry. Defoamer can play a stable role in breaking foam in a wide range of pH and temperature, and can be widely used in all kinds of water-based adhesives and emulsions, such as acrylic resins, adhesives, white latex, polymer adhesives, water-based color paste, etc.
The role of adding glue defoamer is many：
1. Glue defoamer on either floating, or suspended in solution foam have a good effect of elimination, can quickly disperse penetration and reaction with the foam, even if the micro-foam is also the same.
2. Glue defoamer has a not to be underestimated anti-foaming power, in high temperature, strong acidic and alkaline environment can play a role, so that the glue system will not easily appear foam residue phenomenon.
3. Adhesive defoamer is added in low amount, does not have a negative impact on the basic nature of the foaming system, can reduce the cost of defoaming, resource consumption and environmental protection, so that the process can be carried out in a more orderly manner, improve production efficiency, etc.
