Sell Sodium Carboxymethyl Starch Cms

Sodium Carboxymethyl Starch CMS is an effective and economical fluid loss agent in water based drilling fluids, which is a sodium carboxymethyl starch polysaccharide derivative. It is not bacterial degradation when at 120℃, environmentally acceptable and non-toxic. CMS can produce a thin, slick, tough filter cake and promotes faster penetration rates with reducer friction. It can be used in all kinds of drilling fluid systems.

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.
