Sodium carboxymethyl cellulose, an organic substance, is a carboxymethylated derivative of cellulose and is the predominant ionic cellulose gum. CMC-Na is a white fibrous or granular powder, odourless, tasteless, hygroscopic and easily dispersed in water to form a transparent colloidal solution.
CMC Application description
CMC for Coatings Industry is Very suitable.
CMC is widely used as slurry treatment agent for oil industry, synthetic detergent, organic detergent aid, textile printing and dyeing sizing agent, water-soluble gelatinous tackifier for daily-use chemical products, tackifier and emulsifier for pharmaceutical industry, thickener for food industry, adhesive for ceramic industry, industrial paste, sizing agent for paper industry, etc. It is used as a flocculant in water treatment, mainly for wastewater sludge treatment, and can improve the solid content of the filter cake.
Sodium carboxymethyl cellulose is also a kind of thickening agent, because of its good functional properties make it in the food industry has been widely used, it also to a certain extent to promote the rapid and healthy development of the food industry.
For example, because it has a certain thickening and emulsifying effect, it can be used to stabilise yoghurt drinks and increase the viscosity of yoghurt systems; because it has a certain hydrophilic and rehydrophobic effect, it can be used to improve the eating quality of pasta such as bread and steamed buns, extend the shelf life of pasta products and enhance the taste;
Because it has a certain gel effect, it is conducive to the better formation of food gel, so it can be used in the manufacture of jelly and jam It can also be used as an edible coating material, which can be used in combination with other thickeners and applied to the surface of some food products to maximise freshness and has no adverse effects on human health as it is an edible material.
Therefore, edible grade CMC-Na is very commonly used as an ideal food additive in food production in the food industry.
CMC for coatings industry with the following characteristics:
1. Chemically treated and with good dispersibility.
2. The ability to dissolve quickly after the addition of alkali.
3. The solution is free of fibres and has good transparency
4. Very few gel particles, filters do not get clogged and are easy to use
5. Various viscosity ranges, good viscosity stability
6. Uniform reaction has good resistance to enzymatic changes.
7. Good heat resistance.
