Code name: CMC

Molecular formula: [C₆H₇(OH)₂OC₂COONa]

Characteristics: an ionized linearity high molecular material, white or light yellow threadiness powder, non-toxic, odorless. Became transparent ropy liquor when dissolves in cold or hot water.

Quality index:

Instead of degrees (D.S) ≥0.80   purity (%) ≥75

Viscosity 2%25℃: 300-800  PH: 6.0-8.5  granularity(60catalogue)%≥80 dry reduction%≤8

Usage:

Used as additive in the pulp in papermaking: Accelerate the thinning of fiber, shorten the time of pulping, improve the shaping of paper, enhance the effect of sizing; adjust the potential in the pulp, disperse the fiber, improve the papermaking function of machine; increase the keeping rate of various additives, padding and tiny fibers; decrease the pollution charge, improve the fiber bond and the dry and wet degree of paper.

Usage in well drilling: decrease the fluid loss, enhance the viscosity and increase the extracted petroleum in ocean etc.

In other industrial products:

Building materials: used as retarder, water-retaining agent, thickener and binder, make painting with high gas tightness, waterproofness and stretcher, improve the water-retaining property, cohesiveness, uniformity and intensity of beton.

Abstergent: excluding dirt deposition, thicken the soap liquid and slurry.

Paint: keep stable stickiness when rise temperature.

 

Suggested dosage:

1, 0.05-1.5%, according to the request of various products.

2, Soak it by little water, add water and stir it to confect the required liquor. If need other auxiliary materials, please mix them with CMC, put it in the liquor gradually and stir it quickly. At the same time, pay attention to high temperature, because viscosity will be reducing along with the increasing of temperature. Please take care of the package in case of the moisture absorption. It’s non dangerous
