GH-6 consists of various kinds of compounds, such as gluconate and
hydroxycarboxylic acid.
Non-poisonous, non-odor, and non-corrosivity.
Normal dosage: 0.06% ~1.0% ( BWOC ). The amount can be appropriately
increasea with the increase of temperature.
It can reduce the consistency of cement slurry and improve the rheology.
Retard the thickening time efficiently.
Generally used in oil wells whose circulate temperature under bore is between
75℃ to 110℃.
GH-6 is sensitive, so the dosage should be accurately measure.
