SU958377A1 - Method for activating hardening mix - Google Patents

Description

Substances that break down into ions. In a hardening mixture, the ion source is cement. When cement is mixed as a result of its hydration in a solution, Ca-, Al, Fe, 5 Fe, etc. ions are present in a large amount of ions. A filling mixture solution together with electrodes from metals with different normal electrode potentials form a galvanic cell. Electromotive force 10 (EMF) of this element depends on the type of metal and activity of the property.

The activity of the lower during electro-hydraulic shock increases due to the intense grinding of particles tS and the improvement of the hydration process and increases with an increase in the activation energy.

Such an increase in activity occurs up to a certain value of the energy of the TQ discharge, after which the activity practically does not change with an increase in the energy of the discharge.

When activity is pending, reaching-. em of the greatest value, then the emf of the galvanic element also reaches the greatest increase in value. Consequently, the energy of the discharge, corresponding to tvu-. I think the maximum activation of the solution ;, can be determined by the largest value of the potential difference between the measuring elec- troal electrodes, measured after the discharge.

However, the quality of the prepared solution depends also on the time interval between the bits. If the inter-5 shaft is very large, then a part of the solution will pass between the non-activated electrodes. At a small interval of time between discharges, an unreasonably high consumption of elekt-40 roergy will occur.

The time interval between the discharges is determined primarily by the zone of action of the electro-hydraulic effect along the length of the tray. At the same time, if the electrodes are installed on the border of this zone, then at the moment of discharge the mixture in the vicinity of the measuring electrodes will receive some activating impulse, and the difference will

Ala on the measuring electrodes will begin to increase as you approach

cores of the activated solution. Then, when the draw passes through the measuring electrodes, the potential difference will begin to fall. The minimum value of the potential difference. Testifies to the need to apply a new activating impulse.

With a change in the speed of movement of the mixture, the time interval between the discharge No. will change — with an increase in speed. The time interval decreases, with a decrease in speed — an increase.

In order to determine the location of the measuring electrodes, the latter are set at different distances from the discharge electrodes and activated with the selected working energy, and at the same time sampling is performed. The maximum distance at which the maximum strength gain of the cement stone is achieved is taken as a working distance. For a given working distance, set 1 gap between bits per time. nor is achieving the minimum potential of the potentials between the measuring electrodes.

Fordulla invention

The method of activation of hardened mixtures by the action of electrical discharges between the discharge electrodes placed in the mixture, is applied to the mixture, and so on. By the fact that, in order to reduce the power consumption and the quality of activation quality, the potential difference between the measuring electrodes made of different metals placed in the moving mixture is continuously measured, and the energy of the electric discharges and their periodicity are determined by the maximum and minimum values potential difference.
