4. CMC Applications are as follows:
Applications in Coating
1. Control and adjust the flowing property of paint and the sispersibility of the pigment, increase the solid content of paint.
2. Strengthen the water retention value of the paint and avoid the moving of adhesive, so that it can improve the leveling of the paint and quality of the coating.
3. Give good stability to the paint, keep the homogeneity of the paint system.
4. Excellent film forming property, improve the gloss of the coating.
5. Improve the retention rate of the brightener, and increase the whiteness of the paper.
Applications as Wet-end Additive (Pulping)1. Excellent dispersibility helps the shaping of paper and improves the evenness.
2. Improve the inner bond force of cellulose, increase the physical strength of the paper.
3. Enhance the sizing effect.
4. Increase the retention of additives, stuffing and tiny cellulose.
CMC for Sublimation Thermal Heat Transfer Paper Coating
Applications in Surface Sizing1. Increase the fluffing speed of paper obviously and improve the ink absorbability.
2. Excellent flowing and film forming property enhance the stiffness and smoothness of paper.
3. Improve the surface strength and aeration, control curling.
CMC for Sublimation Thermal Heat Transfer Paper Coating
APPLICATION IN PAPERMAKING AREA:
CMC is widely used in White Cardboard, Coated Paper, Carbonless Paper, Transfer Paper, Thermal Paper, Bank note Paper, Offset Paper, Release Paper, Tipping Paper, Cigarette Paper, Decorative Paper, Bond Paper, Map Paper, Food Wrapper, Wallpaper making, Sublimation Thermal Heat Transfer papermaking, etc.

CMC PAC Oil Drilling Grade:
CMC and PAC can reduce water loss, and increase viscosity in drilling fluid, cementing fluid and fracturing fluid. They play the roles of protecting the wall of well, taking drilling trifles, protecting drilling bit, preventing mud loss and increasing drilling rate.
Usage: add to mud directly or glue solution preparation.
Addition: 0.1-0.3% in fresh water mud; 0.5-0.8% in salt water mud.
Chemical CMC Powder for Wallpaper Paper Making
CMC Food Grade
CMC is widely used in food industry, it play the roles of taste improvement, thickening and stabilization when used in various kinds of dairy drinks and seasonings. As an additive of molding, taste improvement, anti-fragmentation, water retaining and tenacity strengthening, CMC is also used in ice cream, bread, cake, biscuit, instant noodle and fast paste foods.
The recommended addition is 0.3-1.0%.
Chemical CMC Powder for Wallpaper Paper Making
CMC Textile Grade
Is ready to replace traditional sodium alginate with about half of the cost.
Chemical CMC Powder for Wallpaper Paper Making
CMC Ceramic Grade
Can be used for water preserving in concrete paste and color paste, as adhesive in concrete, sand, and in adhesive layer for wall paper installation.CMC is used for ceramic embryo, glazing pulp and colored glaze in ceramic industry.
Addition: 0.03%-0.2% used in ceramic embryo; 0.05-0.2% used in glazing pulp; 1.4-4.0% used in colored glaze.
CMC Toothpaste Grade
CMC has an efficiency of adhesion and molding when used in toothpaste, and stabilizes the quality of toothpaste owing to good compatibleness.
The recommended addition is 0.5-1.5%.
Other Industries
As coagulant, water retaining, thickener and binder, CMC is also used in detergent, paint, carpet gum, mosquito coil incense, tobacco, electric welding, mining, battery, printing and others.
5. There are a number of parameters which define the properties of the Sodium Carboxymethyl Cellulose.
√ Purity (active CMC content): inevitably CMC powder is produced with by products that are sodium salts which comes in the product Sodium Carboxymethyl Cellulose content in the product is the purity.√ Viscosity: one of the most interesting characteristics of the CMC powder is the viscosity which can be from low to high. It is measured mostly by digital viscometers at certain temperatures in different solution rates; such as 1%, 2% or 4%.√ Degree of Substituion: is the average number of sodium carboxymethyl groups per anhydroglucose unit on the cellulose back bone. This parameter in some application areas is quite important to control in the product.√ Physical form: the CMC powder can be produced in fine powder to dust-free granule. 6. CMC STORAGE CONDITION
Product should store ventilated, sanitary, cool, dry place, avoid store with toxicant, harmful and caustic material.
