Sodium Carboxymethyl Cellulose CMC-HV
Product Description
Chemical Name: Sodium Carboxymethyl Cellulose (CMC)
Type: CMC-HV is a high-viscosity sodium carboxymethyl cellulose, belonging to water-soluble polymer compounds.
Appearance: White or light yellow powder.
Characteristics: Excellent thickening, suspending, emulsifying, and stabilizing properties. It can significantly increase the viscosity of drilling fluids, reduce filtration loss, and stabilize the wellbore.
Mechanism of Action: By adsorbing onto the surface of clay particles, it forms a stable colloidal structure, reducing the infiltration of filtrate into the formation.
Performance Indicators
Viscosity: High viscosity (1% aqueous solution viscosity typically ranges from 1000-3000 mPa�·s).
Filtration Loss: Significantly reduces API filtration loss (usually
