high efficient CMC--carboxymethyl cellulose

Carboxymethyl cellulose
Usage:paint dyestuffs,paper dyestuffs,textile dyestuffs.oilfield,mining industry,drilling industry.
CMC
Properties
1.Thickening:CMC can produce high viscosity at low concentration.It also acts as lubricant.
2.Water retention:CMC is a water binder,helps incerase shelf life of food.
3.Suspending aid:CMC acts as emulsifier and suspension stabilizer,particularly in icings to contro ic crystal size.
4.Film forming:CMC can produce a film on the surface of fried food,eg.instant noodle,and prevent absorption of excessive vegetable oil.
5.Chemical stability:CMC is resistant to heat,light,mold and commonly used chemicals.
6.Physiologically inert:CMC as a food additive has no caloric value and can not be metabolized.
Characteristics
A. Finely distributed molecular weight,
B. High resistance to acid.
C. High resistance to salt,
D. High transparency,low free fibers.
E. Low gel.
Usage:
1. Printing & dyeing grade CMC featrues:
* good stability of viscosity,*good distributiion uniformity of degree of substitution,*good fluidity of solution,*high water scrubbing rate.
2. Oil drilling grade
Petroleum grade product features:
*high degree of substitution,good uniformity of substitution,*high transparency,viscosity and water loss can be controlled,*suitable for fresh water,sea water,satrated brine slurry,*stabilize soft soil structure,prevent collapse of wall of a well.*can improve mud-making volum,reduce filteration loss.* has excellent performance in drilling of oil.
3 Battery grade
*excellent hydrophilicity,*stable viscosity,high adhesive force,*good transparency and fluidity of aqueous solution,*low metal content.
4 Paper--making grade
CMC is a high--efficiency paper--making auxiliary,and features good moisture retention,dispersibility
CMC's application in paper--making industry
(1) pigment coating
* Control and regulate the rheology of coatings and dispersibility of pigments.
* Get pseudoplasticity of coatings.
* Improve the moisture retention of coatings.
* Has excellent film forming property.
(2) Intracytoplasm adding
* Improve jordaning efficiency,shorten pulping time.
* Regulate electric potential of pulp.
* Improve the retention rate of additives,fillers etc.
(3) Top sizing
* Has excellent rheology and film forming property.
* Improve the brightness and gloss of paper.
*Enhance the stiffness and smoothness of paper.
* Increase the surface strength and abrasion resistance of paper.
