CMC is available in a variety of viscosity grades. Low-viscosity CMC (CMC-LVT) offers excellent dispersion, stabilization, colloidal protection, and film-forming properties. High-viscosity CMC (CMC-HVT) demonstrates exceptionally high thickening efficiency, along with superior water retention, suspension stability, and rheology-modifying characteristics. CAS No.: 9004-32-4 Formula: C6H12O6 EINECS: 618-326-2
CMS is an effective "economical" Fluid Loss Control agent for water-based drilling fluids. Increasing additions of CMS can cause an increase in desired viscosity. Used of CMS does not require any biocide treatment in normal drilling fluid operations. CMS is typically unaffected by normal solids concentrations and products a tough, slick filter cake, which promotes a reduction in friction and potentially increases drilling rates. CMS may be less effective in high levels of Mg and Ca ions and it is recommended that all "high hardness" be treated out prior to CMS addition. The normal dosage is 0.3~0.5 percentages.
PHPA maintains viscosity in solids-free drilling fluid. As a Bentonite extender in low-solids, non-dispersed mud, it can be used along with a small addition of Bentonite to suspend weight material.
xanthan gum Oil drilling grade is used as a drilling mud additive, primarily as a thickener and suspending agent in water-based drilling fluids. It exhibits excellent shear stability and suspension properties. CAS No.: 11138-66-2 Formula: C35H49O29 Appearance: Light yellow to white flowable powder Packaging: 25kg/bag or customized
