Carboxy Methyl Cellulose (CMC) uses
1.Application in textile Industry
With high degree substitution, Sodium Carboxy Methyl Cellulose (CMC) can be used as the thickener in various textile printing color paste, and it has the excellent anti-acid and anti-salt. The viscosity is stable after making up the thickener and printing color paste, and it can fully replace the high quality alginate. The advantages of product are listed as follows:
*Good hygroscopicity, increase the consistent color rate, and enhance the vividness;
*Good Penetration. Deep color absorption and easy off the work intensity for textile embossing;
*Excellent rheoloty, and keep the printing smooth;
*High solubility, high transparency, little gel and good filtrability;
*Good stability of viscosity, water-retention and net permeability
*Easy for desizing, and soft texture.
2. Application in ceramic industry
CMC can be used in ceramic body, glazing pulp, and fancy glaze. Used in ceramic body, it is a good strengthening agent, which can strengthen the mouldability of mud and sand materials, facilitate body shaping and increase the folding strength of the green body. Used in glazing pulp and fancy glaze, it is a binder that plays a role of suspending, deflocculating and water holding.
3. Application in Pharma Industry
In the pharmaceutical industry, Sodium Carboxy Methyl Cellulose can be used as emulsion stabilizer of various kinds of injections such as penicillin and streptomycin. Moreover, it can act as the basic material of various kinds of emulsifiable paste, the adhesion agent of tablets as well as the dispersing agent of barium sulfate and titanium oxide in X-ray vision. It can also be used to fix teeth and to make aperient, styptic, adhesive and contraceptive.
4. Application in Daily Chemical
In toothpaste, body cream and shampoo, Sodium Carboxy methyl cellulose can act as the stabilizing and emulsifying agents to regulate viscosity, stabilize foam, enhance cleansing power and produce fine, smooth quality. Sodium Carboxy methyl cellulose is also an ideal adhesive agent in the production of mosquito coils, footwear uppers, paper boxes, pencils and reconstituted tobacco.
5. Application in Food Industry
Sodium Carboxy methyl cellulose is odorless, tasteless, non-toxic, easily soluble and won’t get bad for long-term storage. Moreover, it has high viscosity and strong shape-preserving capacity, so is widely used in food industry.
it can act as the extender of adhesive agent in the process of jam, sugar, fruit syrup and pungent sauce. In dessert, it enables the tissue to be homogeneous and fine, the appearance beautiful. It can also be used as the stabilizing agent in the production of ice cream. It can function as the shape fixing agent in the production of lemon and grape drinks as well as semi-fluid edible oil and fat apt to rancidity. Furthermore, it can be used as the film forming agent in the surface treatment of vegetables, fruit, eggs and tea leaves to keep the original color and flavor for long.
6.Application in paint and coating Industry
In paint and coating industry, Sodium Carboxy Methyl Cellulose is macromolecule compound with multichain, and the linear chain will open, spread, interact and form the network collide after the water swelling. Meanwhile, the macromolecule chain with oxhydryl has hydration with water and twine with each other, and then increase the water phase viscosity. It has the excellent compatibility in water or in organic solvent, as well as the pigment. It used as thickener, dispersant and stabilizer in coating industry.
7. Application in pesticide and plastic industries
Sodium Carboxy Methyl Cellulose can also be used as the glazing and coloring agents of leather, surface treatment agent of filmstrip and photo negative film, stabilizing agent of rubber paste, foam stabilizer of fire foam, and dispersing, stabilizing as well as emulsifying agents in pesticide and plastic industries.
8.Application In the paper-manufacturing industry
In the paper-manufacturing industry,CMC displays many excellent performance in paper-making technology. it is higher valued by the majority of paper engineers and is widely used in the production of paper and paperboard, such as paper and paperboard coating process, coating rheology modifier, water – retention agent, film-forming agent, auxiliary adhesives, wet end retention enhancers and surface sizing agents, grinding aids, filler modifier and the flocculating agent which used in waste water treatment etc.
9. Application in fabric finishing
Paint the CMC aqueous solution on fabric, and then after the acetic acid treatment, it can be produced a special fabric with airtight and water proof. Treat the fabric with CMC aqueous solution first and treat with the easy decomposition of quaternary ammonium salt, then after drying, burnishing and heating at the appropriate phrase, and it can form a waxy fabric which is insoluble in coating.
10.Application in mining industry
Sodium Carboxy methyl cellulose is used in mining industry as pellet binder and flotation inhibitor. CMC is a component of the binder for mineral dust shaping and meanwhile the binder is an indispensable ingredient for pellet production. It can improve the properties of wet pellet, dry pellet and calcinated pellet. Due to its good binding property and pellet forming property, the green pellet with CMC has excellent antiknock performance, high compressive strength and dropping resistance. It can also increase the grade of pellet. CMC is an adjusting agent in floating selection process, it is used as the silicate gangue inhibitor, controlling the lead in the separation process of copper and lead, sometimes it is used as dispersant for mineral mud.
11.Application in Toothpaste industry
Toothpaste is a dispersed system composed of abrasives, moisturizers, former, essence and water etc. CMC is one of the most important raw materials in toothpaste and plays the role of mixing evenly the fluid and solid material, making the toothpaste molding, flowing, moderate thickness, brightness and smoothness. Furthermore, it helps the powders and liquids emulsify evenly to become the stable soliquoid, and plays the extremely important role in stability and diffusivity.
CMC is mainly used as thickener in toothpaste to prevent its solids from liquids. It makes the toothpaste thickness, strip shape and good frame and not be runny, soft and thin on the toothbrush, and meanwhile, it keeps brightness and smoothness.
*The Substituent is distributed evenly and appropriately. It has the good property of salt tolerance, acid tolerance, anti-enzyme and strong hydrophilicity.
*Good water solubility and water conservation, the oil and water do not separate with each other.
*Excellent moisture retention and strip shape.
*Appropriate viscosity and thixotropism, good property of shear-thinning. Easy dispersion and swelling in the production process makes filling production convenient.
*Good protection for colloid and Strong emulfication.
*Helps suspension of paints and abrasives.
*Helps essence emanation and good taste.
*Moderate flowing of the paste, easy to be transported and easy to be squeezed from the toothpaste tube.
*Good flexibility and diffusivity, and paste squeezed with less tail.
Produce the different CMC with thickening and rheologic property through adjusting and controlling of the production formula as well as production technology. It will be applicable to producing the diverse toothpaste.
