Application of CMC in other industries


  In detergents, CMC can be used as an anti-soil redeposition agent, especially the anti-soil redeposition effect on hydrophobic synthetic fiber fabrics is obviously better than that of carboxymethyl fibers.
  CMC can be used to protect oil wells as mud stabilizer and water retention agent in oil drilling. The dosage of each oil well is 2.3t for shallow wells and 5.6t for deep wells;
  In the textile industry, it is used as a sizing agent, a thickener for printing and dyeing paste, textile printing and stiffness finishing. When used as sizing agent, it can improve solubility and viscosity change, and it is easy to desizing; as a stiffening agent, its dosage is above 95%; when used as a sizing agent, the strength and bendability of the serosal film are obviously improved; the use of regenerated fibroin The composite membrane formed with carboxymethyl cellulose is used as a substrate for immobilizing glucose oxidase, and glucose oxidase and ferrocene carboxylate are immobilized, and the prepared glucose biosensor has high sensitivity and stability. Studies have shown that when the silica gel homogenate is prepared with a CMC solution with a concentration of about 1% (w/v), the chromatographic performance of the prepared thin-layer plate is good. High layer strength, suitable for various dosing techniques, easy to operate. CMC has adhesion to most fibers, which can improve the bonding between fibers, and the stability of its viscosity can ensure the uniformity of sizing, thereby improving the efficiency of weaving. It can also be used as a finishing agent for textiles, especially for permanent anti-wrinkle finishing, which brings changes in durability to the fabric.
  CMC can be used as anti-settling agent, emulsifier, dispersant, leveling agent and adhesive for coatings, which can make the solid content of the coating evenly distributed in the solvent, so that the coating does not delaminate for a long time, and is also widely used in paints .
  When CMC is used as a flocculant, it is more effective than sodium gluconate in removing calcium ions. When used as a cation exchange, its exchange capacity can reach 1.6 ml/g.
  CMC is used as a paper sizing agent in the paper industry, which can significantly improve the dry and wet strength of paper, as well as oil resistance, ink absorption and water resistance.
  CMC is used as a hydrosol in cosmetics and as a thickener in toothpaste, and its dosage is about 5%.
  CMC can be used as flocculant, chelating agent, emulsifier, thickener, water-retaining agent, sizing agent, film-forming material, etc. It is also widely used in electronics, pesticides, leather, plastics, printing, ceramics, household chemicals, etc. Due to its excellent performance and wide range of uses, it is constantly developing new application fields, and the market prospect is extremely broad.
