Brief: Watch this overview to discover why many professionals pay attention to this approach. In this video, we demonstrate how Ammonium Carboxymethyl Cellulose (CMC-NH4) serves as an effective binder solution for high-quality SCR denitrification catalysts. You'll see how this non-toxic white powder dissolves in cold water to create viscous solutions and learn about its application in honeycomb ceramic production to enhance catalyst performance and longevity.
Related Product Features:
  • Ammonium carboxymethyl cellulose is a non-ionic cellulose derived from natural polymer materials through chemical processing.
  • This white powder is odorless, tasteless, non-toxic and dissolves in cold water to form transparent, viscous solutions.
  • It provides multiple functions including thickening, adhesion, dispersion, emulsification, and surface activity.
  • CMC-NH4 is specifically designed for SCR denitrification catalysts to prevent alkali metal-induced deactivation.
  • It offers stronger cohesion and less residual ash after roasting compared to traditional CMC binders.
  • The product significantly improves the performance and service life of SCR catalysts in industrial applications.
  • Its molecular structure is C6H7O2(OH)2OCH2COONH4 with the formula C8H15O7N.
  • Widely used in honeycomb ceramics, lithium-ion batteries, supercapacitors, and electronic packaging processes.
FAQs:
  • What makes Ammonium Carboxymethyl Cellulose (CMC-NH4) superior for SCR denitrification catalysts?
    CMC-NH4 addresses the issue of alkali metal-induced deactivation in conventional CMC, which can damage SCR catalyst structure and active sites. It provides stronger cohesion and less residual ash after roasting, significantly improving catalyst performance and service life.
  • What are the key physical properties of Ammonium Carboxymethyl Cellulose?
    CMC-NH4 is a white or slightly yellow powder that is odorless, tasteless, and non-toxic. It dissolves in cold water to form transparent, viscous solutions and has viscosity ranging from 100-300 (B type in 1% aqueous solution), with pH between 5-8 and ash content below 0.5%.
  • In which industrial applications is Ammonium Carboxymethyl Cellulose commonly used?
    CMC-NH4 is widely used in the production of honeycomb ceramics for SCR denitrification catalysts, lithium-ion batteries, supercapacitors, and electronic packaging. It improves product yield through its thickening, adhesion, dispersion, emulsification, and surface activity properties.
