膠黏劑基礎(chǔ)之1——消泡劑:機理與選擇(英文版)
|
||||||||||||||||||||||||

Foaming is a problem that plagues many adhesive applications. Emulsion adhesives are especially prone to the troubles and expensive consequences created by foaming. When any emulsion is moving in contact with air, there is a risk of foam formation. Therefore, foam is generally encountered when mixing the adhesive or during high speed coating processes. Fortunately it is possible to control foam by integrating certain additives to the adhesive. Defoamers are generally added to preexisting foam to eliminate the foam, and antifoaming agents are added before the formulation to prevent it from foaming. There are many antifoaming agents on the market. Selecting the proper type for a specific application can be a daunting task since optimal antifoaming properties will depend heavily on the specific adhesive system and on the processes employed in formulation or conversion. This article will attempt to provide a review of the problems caused by foam formation, the mechanism and factors that cause foaming, and the chemical agents that can be used to hinder or eliminate the formation of foam in emulsion adhesive systems. This will hopefully provide the reader with a guide to the optimal selection and use of antifoaming agents. |
