[Rheologic investigation of electrode gels. III. Study of temporal changes of gel structure].
In the publication consisting of 3 parts nine electrode gels have been investigated siú of them are used in hospital pharmacies of this country. Character and stability of gel structure have been studied and controlled by rheological methods. Structural forces have been numerically characterized with maximum and equilibrium viscosity, values of "M and B coefficients" and directional tangents of viscosity curves. Mechanical and thermal stability have been determined, changes for six months storing have been studied by means of all rheological parameters, respectively. Besides investigating rheological parameters electric conductivity values--which are important in respect of practical use of electrode gels--have been determined too. On the basis of results Carbopol "G" designated gel has been found to be the best its use has been proposed not only in supersonic tests but also in ECG.
