The use of carboxymethyl cellulose is the cellulose ether with the best physical and chemical properties and the most widely used in the cellulose ether industry, and the use of carboxymethyl cellulose belongs to non-ionic cellulose ethers. Because HPMC has excellent properties such as thickening, emulsification, film forming, protective colloid, moisture retention, adhesion, enzyme resistance and metabolic inertness, carboxymethyl cellulose is widely used in construction, latex coatings, medicine, polychlorinated Ethylene, daily chemicals, ceramics and agricultural production.
The use of carboxymethyl cellulose In the construction and building materials industry, the main function of HPMC is to increase viscosity, thicken, retain water, lubricate, improve the processability and pumpability of cement and gypsum; the use of carboxymethyl cellulose in latex Coatings are mainly used as protective colloids, thickeners and pigment suspending agents; the use of carboxymethyl cellulose in the pharmaceutical industry is mainly used for preparation production, as tablet coating and forming binders, and can be used for sustained release The production of pharmaceuticals; the use of carboxymethyl cellulose is mainly used in personal protective equipment in daily chemicals, and the use of carboxymethyl cellulose can improve the emulsification, anti-enzyme, dispersion, adhesion, surface activity, film-forming, Moisturizing, foaming and other properties; carboxymethyl cellulose is also used in the production of polyvinyl chloride, mainly used as a dispersant in the polymerization reaction of the suspension polymerization system, and currently has a wide range of production in the world’s suspension polyvinyl chloride production application. In addition, the use of carboxymethyl cellulose is also used as a bonding agent for ceramic industry blanks and a dispersant for glaze; in agriculture, carboxymethyl cellulose is used to treat crop seeds, which can increase the germination rate, which can not only moisturize but also protect the skin. Can prevent mildew and so on.
Introduction to the use of carboxymethyl cellulose:
The use of carboxymethyl cellulose is a non-ionic cellulose ether made of natural polymer material refined cotton through a series of chemical processing. The appearance of carboxymethyl cellulose is white powder, non-toxic, tasteless and odorless. It can be dissolved in cold water to form a transparent viscous colloid.
- The use of carboxymethyl cellulose has very good water retention performance. Even if the mortar containing carboxymethyl cellulose is applied to a highly water-absorbent substrate, it can maintain the operating performance of the mortar for a long time, and the use of carboxymethyl cellulose is compatible with many surfactants and water-based polymers. The use of carboxymethyl cellulose can prolong the opening time of cement mortar, improve work efficiency, improve shrinkage and crack resistance, and improve surface quality.
- Use of carboxymethyl cellulose The particles are relatively fine, generally reaching 120 meshes, which is more convenient to mix with cement mortar, gypsum, lime and other materials, so that these mixtures are not easy to agglomerate when dispersed in water.
- Carboxymethyl cellulose can be used in cement mortar, external wall thermal insulation system and similar products, especially for external wall thermal insulation system.
- The use of carboxymethyl cellulose has good lubricity, and the material after using hydroxypropyl methyl cellulose (HPMC) can greatly enhance the operating performance of the material, making it easier to apply the trowel and improving Anti-sliding ability of mortar.
- The use of carboxymethyl cellulose can enhance the cohesive force, help the mortar to form high mechanical strength during setting, and improve the cohesive strength and shear strength of the mortar.
