HEC with our performance in oilfield is our specially produced non-ionic soluble cellulose ethers derived from natural fibers.HEC has excellent functionalities in thickening, suspension, binding, emulsion, film stability, dispersion, water retention, anti-microbial properties and colloid protection, etc.It can be widely used in paints, cosmetics, oil drilling and other industries.
HEC provides high performance in increasing viscosity,and is excellent in control filtration loss in oilfield drilling and completion fluids.HEC is stable to various salts,even at Calcium salt solution.Oilfield fluids containing HEC exhibit high apparent viscosity,high yield point and low fragile gel strength.Its shear-thinning behavior known as pseudoplasticity help both increase penetration rates under high shear and provide excellent suspending action for optimum hole cleaning under low shear while viscosity is regained.
Introduction of Landcel HPMCThe alias of Hydroxypropyl methyl cellulose is hypromellose; cellulose hydroxypropyl methyl ether, English abbreviation: HPMC, It uses cotton cellulose as raw material, and is produced by special etherification under alkaline conditions , the whole process is completed un
Tile adhesives are cement and/or polymer dispersion-based systems. The rheological additives used for these are mainly cellulose ethers, which provide the right consistency for the application, sag resistance of wall tiles, water retention for the optimum hardening of cement, and the control of open
