LRCP physical drag reducer Long acting physical drag reducer gel liquid drag reducer Bentonite drag reducer manufacturer

Description :

　　The unique long-term effect and stability of liquid drag reducers are unmatched by other drag reducers, mainly manifested as:

　　l、 Stable physical performance, with no change in performance after high current impact;

　　2. Strong water absorption and retention, and the drag reduction effect is not affected by seasons and climate;

　　3. High viscosity, strong adhesion, high gum value, not easily lost with water:

　　4. The grounding body has a high anti-corrosion effect, which extends the service life of the grounding body.

　　2、 Principle of Liquid Resistance Reduction and Corrosion Prevention

　　The direct methods to reduce grounding resistance are to extend the grounding conductor, expand the grounding network area, or drill deep wells. However, these methods are sometimes affected by the site and the increase in steel consumption may not achieve the expected effect, making them very uneconomical. The principle of liquid resistance reducer is to increase its surface area and reduce the contact resistance with the grounding electrode, thereby reducing the total resistance of the grounding body. The composition of liquid drag reducers can be divided into electronic conductivity type and ion conductivity type. The electronic conductivity type is less affected by climate factors, has good long-term performance, and does not produce corrosion.

　　The pH value of liquid resistance reducing agents is weakly alkaline in the range of 9-12, because alkaline substances can form a passive film on the surface of steel grounding electrodes to protect them from soil corrosion. Due to the unevenness of soil composition, buried electrodes may experience battery corrosion. Liquid resistance reducing agents tightly wrap around the electrode to prevent the infiltration of other impurities, so that ion exchange that causes corrosion does not occur in the electrode, but at the interface between the liquid resistance reducing agent and the soil, thereby achieving the purpose of protecting the grounding electrode and reducing corrosion.

　　3、 Main technical indicators of liquid drag reducer:

　　1. The main components of liquid drag reducer are Na, Ca, Fe, Mg, Ti, C and other elements, with a black brown color powder appearance. Does not contain toxic elements and does not pollute the environment.

　　2. Specific gravity: 1.25 tons/cubic meter in dry powder state.

　　3. Electrical resistivity: 0.54 Ω m

　　4. Acidity and alkalinity: pH value=10.2;

　　5. The average corrosion rate of low carbon steel and galvanized steel when buried underground is less than 0.0005mm/year;

　　6. Compressive strength:>10NPa (equivalent to the strength of concrete grade 100);

　　7. Particle size: 200 mesh sieve residue ≤ 5%;

　　8. Resistance reduction rate: 60-95% (the higher the soil resistivity, the more significant the resistance reduction rate)
