RHEOLOGICAL PROPERTIES OF FOAM FORMERS LIKE PIRENA-1, SOFIR, ALPEN, MOUSSOL, STHAMEX, PIANOL

Abstract

Firefighters uses surfactants in the form of wetting agents, to change the surface tension of aqueous solutions and to create special firefighting foam of various multiplicity. The main classes of surfactants that firefighters use are surfactants general purpose and surfactants special purpose. Adding to water surfactants have a special affect on a hydraulic characteristics of the fluid flow inside the firefighting equipment, hydraulic characteristics of compact and sprayed jets which were creating by devices for their supply like branch pipes, nozzles, sprinklers, etc. Rheological properties have such affect on hydraulic characteristics of surfactants solutions. Often, data about rheological properties of modern firefighting foam absent or insufficient. There are research results of modern foam formers of foreign and domestic production in our article. Also we studied the similarity of the main rheological characteristics to the characteristics of foaming agents that were established earlier.
