DYM6 can be absorbed on the surface of the cement hydrate to inhibit contact with water and chelate with Ca2+ to prevent crystal nucleus from forming early. Therefore ,it can retard thickening time
Characteristics:
DYM6 consists of gluconates low molecular weight organic acid,etc
Appearance: colorless fluid, density 1.1g/ cm3, non-poisonous, non-odor and non-corrosivity
Normal dosage:1.0%-2.5%(BWOC),it is sensitizer for temperature,should add more with of increasing of temperature
Reduce consistency of cement slurry and improve the rheology
Suitable temperature:circulate temperature under bore is 110-160℃(BHCT)
