Brief: Our team walks you through how Ammonium Carboxymethyl Cellulose (CMC-NH4) performs in SCR catalyst production. This video demonstrates its role as a specialty adhesive that prevents alkali metal-induced deactivation, showcases its strong cohesion and low residual ash properties, and explains how it enhances catalyst performance and service life in industrial applications.
Related Product Features:
  • Ammonium carboxymethyl cellulose (CMC-NH4) is a non-ionic, white powder derived from natural cellulose.
  • It dissolves in cold water to form a transparent, viscous solution and is odorless, tasteless, and non-toxic.
  • CMC-NH4 functions as a thickener, adhesive, dispersant, emulsifier, film-former, suspending agent, adsorbent, gelant, and surface-active agent.
  • It is widely used in honeycomb ceramics, lithium-ion batteries, supercapacitors, and electronic packaging to improve product yield.
  • CMC-NH4 specifically addresses alkali metal-induced deactivation in SCR denitration catalysts, enhancing their performance and longevity.
  • It offers stronger cohesion and produces less residual ash after roasting compared to traditional CMC binders.
  • The product has a molecular formula of C8H15O7N and structure C6H7O2(OH)2OCH2COONH4.
  • CMC-NH4 is a cost-efficient binder for SCR catalysts and is available for immediate shipment.
FAQs:
  • What is the primary application of Ammonium Carboxymethyl Cellulose (CMC-NH4)?
    CMC-NH4 is a specialty adhesive primarily used in high-quality SCR denitration catalysts to prevent alkali metal-induced deactivation, improve performance, and extend service life.
  • How does CMC-NH4 compare to traditional CMC in catalyst production?
    CMC-NH4 offers stronger cohesion and significantly less residual ash after roasting, which helps protect the catalyst structure and active sites, enhancing overall market competitiveness.
  • What are the key physical and chemical properties of CMC-NH4?
    CMC-NH4 is a white or slightly yellow powder, odorless and non-toxic, with a viscosity of 100-300 (B type in 1% aqueous solution), pH of 5-8, drying loss of 10-20%, and ash content below 0.5%.
  • Do you provide samples of CMC-NH4 and what are the terms?
    Yes, we provide free samples up to 500g, but the shipping costs are borne by the buyer. Sample delivery typically takes 7-10 working days.
