1.Food industry use : 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.
2. Industries used in: oil well drilling, ore
drilling, textiles, ceramics, food industry, toothpaste industry,
detergent industry, paper industry, tobacco
industry.
3.types:food
grade CMC, detergent grade CMC, Toothpaste CMC, paper making grade
CMC, oil drilling grade CMC, coating grade CMC, textile grade CMC,
gum CMC, ceramic CMC, etc.
4.Toothpaste-grade CMC: Many
kinds of thickener can be used in toothpaste, but CMC is the most
extensive. CMC acts as colloid that helps shape and conglutinate
toothpaste andprevent the separation of friction
agent,the dense-degree
suit and can keep the stable cream body appearance. CMC solution
has good clearness and good rheology.
5.Detergent-grade CMC: Effectively prevent
washes from becoming contaminated after being washed by synthetic
detergent. Add 0.**2 percent only, you can get satisfactory result.
Because the action of static between fomite granule with minus
charge and CMC molecule with minus charge itself.Chart **1 is the
effect of synthetic charge cleaning fomite effect and whiteness
degree holding. Make washing liquid
more viscouse and the effect of washing more
stable.
6.Mosquito-repellent incense-grade
CMC: Every group evenly mixed and able to replace elm
wood powder, so it has better formability and smoother surface.
Improved toughness of mosquito -repellent incense, which can
prevent from denting and cracking. Each group of
mosquito-repellent incense compatible to achieve better medicine
effect.
7.Paper-grade CMC: CMC sizing for
paper coating, can be used to control and regulate the coating
rheology and dispersion, improve the coating solid content,
enhanced coating water retention and lubrication, to improve the
coating quality, prolong the service life of the scraper,make the
paper with high lubrication gloss and ink
absorption Application in
pulp can promote fiber shortening refinement, beating time, adjust
the plasma potential, dispersion fibers and improve paper machine
making ability. When sizing of
paper in the paper surface,CMC can reduce pores, improve lipid
paper , the surface gloss of paper, surface strength and sizing
degree, enhanced stiffness, paper smoothness, reduce hair off
powder, improve the printing
quality.
8.CMCcan enhance the cohesive force of blank when
used in ceramic blank,make the body easy molding, improve the
flexural strength, improve the stability of raw materials,
processing is more suitable for the machining of ceramic products,
improve the processing speed of the green bodies, reduce processing
costs,at the same time,can make the
water even evaporation of the blank cloth, prevent the dry
cracking, increase the rate of qualified
product. CMC is used for
glaze ceramics as stabilizer and adhesive, can make the glaze
ingredients evenly dispersed, used in ceramic tile glaze and glaze,
can increase the binding force of glaze and
body.Itcan improve the surface tension, increase the
smoothness of glaze, avoid producing spalling and bubble formation
due to changes in the strength of green body glaze, reduce glaze
pinholes after drying, improve the quality of ceramic
products.
9.Paint-grade CMC: 1.Orient brand CMC is a
good thickener used in paint
industry. 2. It is
compatible with most surfactants and stabilizers in waterborne
system. 3.It can change
therheological properties of the
coating.
*0.CMC in drilling
fluid used as filtrate reducer, effect is formed by low
permeability, flexibility, dense filter cake on the borehole wall,
as far as possible to reduce the filtration loss. Used as
suspending agent, plugging agent and thickener in low solid
drilling fluid. PAC is a kind of
high molecular weight poly anionic cellulose, easily dispersed in
all water-based drilling fluid ,and it can be used from freshwater
to saturated brine drilling fluid . At low solid polymer drilling
fluid, can significantly reduce the filtration loss and thinning of
mud cake, and has a strong inhibition to shale hydration. And it
has good temperature tolerance and salt
resistance.
