Products
Function and Application
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
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 & PAC
for oil drilling
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
Ceramic Grade
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
Paper Grade
In making paper, CMC is used in making pulp so as to improve the retention rate and increase humidity and strength; when used in surface sizing, CMC can improve internal adhesion, decrease printing dust and enhance printing quality as molding reagent. In paper coating, CMC also helps the dispersion and fluidity of paint, improves appearance of paper and smoothness, upgrades optical performance and printing adaptability.
Addition: 0.3-1.5%.
CMC
Detergent Grade
Effectively prevent washes from becoming contaminated after being washed by synthetic detergent.Add 0.5-2 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. Make washing liquid more viscouse and the effect of washing more stable.
Additon:0.5-2%
CMC for other industries
As coagulant, water retaining, thickener and binder, CMC is also used in paint, carpet gum, mosquito coil incense, tobacco, electric welding, textile, battery, printing and others.
The variety of CMC grades are mainly based on:
· Purity
· Viscosity
· Degree of Substitution
· Particle Size
Which can be customer-made as per client's requirements.
Packing
