Products Description
Carboxymethyl cellulose (CMC)
Carboxymethyl cellulose (CMC) is a white powder or flocculant with stable performance and easy solubility in water. Its aqueous solution is neutral or alkaline transparent viscous liquid, soluble in other water-soluble adhesives and resins, and insoluble inorganic solvents such as ethanol. CMC can be used as adhesive, thickener, suspending agent, emulsifier, dispersant, stabilizer, sizing agent, etc.
The role of the product.
Sodium carboxymethyl cellulose is widely used as sizing agent in textile industry, replacing grain. Practice has proved that product sizing not only saves a lot of grain and oil, but also is much superior to starch and animal glue. In cotton, silk, wool, chemical fiber, synthetic fiber or blended fabric, let's look at the application value of sodium carboxymethyl cellulose in textile printing and dyeing.
(1) The sodium carboxymethyl cellulose aqueous solution is clear, transparent, uniform, and stable, and its viscosity is not affected by mechanical force, and there is no change during circulation or pump mixing.
(2) The aqueous solution of the product is viscous and can form a smooth, wear-resistant and flexible film on the surface of the warp yarn, which can bear the strength, relative vitality and friction of the loom, thus providing favorable conditions for weaving more fine fabrics and high-speed production.
(3) The yarn treated by water soluble machine is easy to dry, shiny and soft, and desizing is very convenient, without chemical treatment, and does not consume desizing agent and fuel.
(4) The yarn and fabric treated with sodium carboxymethyl cellulose aqueous solution will not turn yellow and moldy, and can greatly reduce or eliminate the defects, spots and oil stains.

The role of the product.
1. Select appropriate reaction conditions and the distribution of product substituent molecules to greatly reduce the detection fineness in glaze paste.
2. It is free of colored impurities and can be burned out to ensure the cleanness of the glazed surface of ceramic products.
3. Sodium carboxymethyl cellulose can stabilize the chemical and physical properties of glaze paste and improve the efficiency of glaze paste preparation.
4. Increase the strength of raw glaze, reduce the drying shrinkage of glaze, prevent defects such as rolling glaze and lack of glaze, make the combination of embryo and glaze firm, and facilitate process operation.
5. The glaze layer is uniform, forming a flat and dense glaze, and the glaze is smooth after firing.
6. Good rheology, improve the fluidity of glaze slurry, and facilitate the glaze spraying operation.
7. The amount of CMC added affects the concentration in the glaze paste. Regardless of the use of high, medium and low viscosity CMC, the viscosity of the glaze paste increases with the increase of the amount of sodium carboxymethyl cellulose.
8. CMC can improve the plasticity of the clay by making the blank adhesive in the ceramic industry.
9. CMC is used as a flow control agent in ceramic glaze.
