  • Commodity name: CMC for tile production

Classification

Sodium carboxymethyl cellulose (CMC) in ceramic tile production primarily improves product quality by enhancing slurry properties, strengthening the body, and optimizing glaze adhesion. Its specific functions are as follows:

Improving Slurry Rheology:CMC dissolves in water to form a stable colloidal solution, regulating the viscosity and flowability of the slurry, preventing particle sedimentation, and improving molding efficiency. Its polymer structure helps the slurry disperse evenly, reducing defects during the molding process.

Enhancing Body Strength and Plasticity: CMC enhances the adhesion between powder particles through its network structure between molecular chains, improving the mechanical strength of the green body and reducing cracking and breakage during drying and sintering. Simultaneously, its water-retention properties extend working time, adapting to different molding processes such as slurry casting and pressure filtration.

Optimizing Glaze Properties:In glazes, CMC acts as a thickener and suspending stabilizer, increasing glaze slurry viscosity, preventing sagging and accumulation, and ensuring uniform glaze adhesion. Its electrostatic repulsion improves glaze dispersibility, reduces pinholes and bubbles, and enhances glaze smoothness and wear resistance. 
Reducing Production Defects :CMC's water-retention properties control the uniform evaporation of moisture in the body, preventing dry cracking caused by excessively rapid drying. During high-temperature firing, its film-forming protective glaze components are released stably, reducing glaze surface defects.

CMC HV/CMC LV/PAC LV/PAC HV/PAC R-Oil Drilling Grade

CMC and PAC can be used in drilling fluid, fixing fluid and fracturing fluid. In drilling fluid, it works as viscosifier, filtration reducer, and rheology controller; in fixing fluid, it is used to control fluid viscosity, suspend heavy objects, and avoid fluid loss; also in fracturing fluid, it is used to carry stuffing and avoid fluid loss. Our product can meet API 13A, or we can produce according to customer’s requirement.

CMC-Mining Grade

CMC 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.

CMC-Paper making Grade

CMC(sodium carboxymethyl cellulose) 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.

CMC-Ceramics Grade

CMC(Carboxymethyl cellulose) is good agent used in Ceramic green body,glaze pulp,ceramic decalcomania and ceramic penetration glaze.CMC can make the glaze smoothly and improve the quality of glazed surface through its bonding, water-retaining, suspending performance. CMC can enhance the clay materials plasticity, improve the body shape, multiply green-pressing strength, reduce the breakage greatly. As an efficient body enhancer, it is no residue after burning, no side effects, and added less quantity compared with other enhancers.
