Experiments in the generation of high expansion foam/ experiences sur la production de mousse a haute expansion/ experimente zur erzeugung von stark blahendem schaum

The author describes a method developed to determine the effectiveness of various high expansion foaming agents based on the rate of foam production and film stability. Three foaming agents were studied in detail. The parameters governing the foam production, such as the nature and concentration of the foaming agents were investigated as a basis for the design of a foam generator.L'auteur a mis au point un essai de d\ue9termination de l'efficience des agents producteurs de mousse se basant sur les crit\ue8res de rapidit\ue9 de formation de la mousse et de son taux d'affaissement. Il a entrepris des \ue9tudes en vue d'\ue9laborer des agents actifs. Il a utilis\ue9 un mat\ue9riel de type habituel pour l'\ue9tude des param\ue8tres r\ue9gissant la production de mousse, tels la nature de l'agent, la forme et les mat\ue9riaux constitutifs du r\ue9seau formateur.Peer reviewed: NoNRC publication: Ye
