Product?Overview
CMC is?nonpoisonous and tasteless white or light yellow?free-flowing?powder with stable properties and is soluble in water. It is water-soluble polymer under chemical modification. Its water solution?is neutral?or?alkaline transparent viscous liquid. In petroleum?exploration?and?drilling process, it is mainly used as the filtrate reducer of drilling fluid, to increase the viscosity and yield of mud. With favorable carrying performance, it improves the rheological property of drilling fluid. CMC can be used as bonding agent, thickening agent, suspending agent, emulsifying agent, dispersing agent, stabilizing agent, sizing agent etc.
Product classification and code:
