Gerneral Overview
Sodium carboxymethyl cellulose (CMC) 5000 mPa·s construction grade is a medium-viscosity multifunctional anionic cellulose ether. As a cost-effective building modifier, our cmc cellulose balances thickening, water retention and fluidity for conventional mortars.
Core Product Advantages
1. Balanced Overall Performance: Moderate viscosity takes into account both fluidity and water retention, making it a cost-effective thickening and water-retaining choice for ordinary mortars.
2. Good Construction Fluidity: Endows mortar with excellent flow and leveling properties, ensures labor-saving construction and adapts to mechanized construction.
3. Drying Shrinkage Crack Resistance: Effectively retains moisture in mortar, reduces drying shrinkage cracking and improves finished product quality.
4. Wide Compatibility: Compatible with both cement and gypsum-based systems, and can be compounded with most construction additives.
Product Specifications
Drilling Grade sodium carboxymethyl cellulose CMC-LV is a low-viscosity, cost-effective anionic cellulose ether and a specialized fluid loss additive for conventional water-based drilling fluids. It has minimal impact on the rheological properties of drilling fluids, reduces fluid loss and improves filter cake quality without basically increasing system viscosity, and has basic salt and calcium resistance. With fast dissolution and good compatibility with conventional drilling fluid additives, it is applicable to high-density, high-solid fresh water drilling fluids for medium-shallow wells, as well as workover fluids and cementing slurry systems. It can effectively control fluid loss and protect wellbore walls, meeting the requirements of conventional low-cost drilling operations.
