CMC Textile Grade:
CMC can form a sheet which is firm, strong with a certain soft and wear resistant, and make itself stick well with the fiber surface. In addition, it gives the chaine sufficient elongation characteristics, increases the textile strength in the process of manufacturing, enhances the production efficiency and takes thickening effect as well. It can be widely applied in the textile industry such as warp sizing, textile printing and fabric finishing etc.
1. Application in Warp Sizing
After starching with CMC and drying, it can form a sheet which is firm, strong with a certain soft and wear resistant, and make itself stick well with the fiber surface. In addition, it gives the chaine sufficient elongation characteristics, increases the strength of the chaine, and reduce the dusting-off rate. CMC which is applied in textile will show the advantages as follows:
*Green products, eco-friendly, and full biodegradation;
*Easy pulping, no heating up and boiling down, and can be dissolved by cold water. Low carbon and energy saving;
*No gel sedimentation, and no crusting, no foaming inside the size vat and pipe;
*Temperature resistance, antibiosis, and stability of size viscosity;
*Easy dividing yarn and no bonding even in the high humidity weave workshop;
*Tough and wear resistance of the size sheet; enhance the weave efficiency, and reduce the yarn breakage to the minimum;
*Without enzyme desizing, and the gray cloth can be scoured or decolorized directly.
2. Application in Textile Printing
CMC, with the ultra-high degree substitution, can be used as the thickener in various textile printing color paste, and it has the excellent anti-acid and anti-salt ( that is, electrolyte endurance). 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.
3. 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.
CMC Paint Grade:
CMC 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. It usually can replace the Hydroxyethyl Cellulose HEC in Latex paint.
Detergent grade CMC:
CMC can be used as THICKENER / thickening agent for liquid detergents, thickening agent for soap.
Detergent grades are mainly used in powder and cream type for detergent production, as well as in soap making industry.
With the character of emulsifying and gel protection, CMC will produce the anion during washing and it makes the washed surface and the dirt granule be negatively charged. It prevents re-sticking of the dirt which will be removed by detergent during the cleaning rinsing process. So, the dirt granule has the phase separation property in aqueous phase, and has the repellency with the washed material surface of solid phase. Place dirt then deposit on the washed material, and it can make the white textile keep the whiteness and colored textile bright. CMC can replace hydroxyethyl cellulose (HEC) and Hydroxy propyl methyl cellulose (HPMC) as THICKENER for liquid detergents, which can reduce production cost.
In making soap, adding an appropriate amount of CMC helps to greatly improve the quality of soap. It enables soap to be pliable and flexible and thus convenient for pressing and processing.
The different types of detergent grades of CMC are produced in the limits of detergent grade specifications but they will be divided into different variations due to customer demands. The customer satisfaction, price sensitivity and other expectations are fully covered by these variations.
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.
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%.
CMC Textile Grade
Is ready to replace traditional sodium alginate with about half of the cost.
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%.
CMC Papermaking Grade:
Our CMC can totally replace Finnfix 2, Finnfix 5, Finnfix 10, Finnfix 30, CPKelco CMC, Bondwell QP-10, QX-5, QX-10
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. We have different paper making grades of CMC to meet the different customers' requirements.
Other Industries
As coagulant, water retaining, thickener and binder, Sodium Carboxymethyl Cellulose CMC is also used in paint, carpet gum, mosquito coil incense, tobacco, electric welding, mining, battery, printing and others.
