Application of cellulose ether
1. Application in Silicate Industry
In ceramic industry, Sodium Carboxymethylcellulose can be used as the rough adhesive agent, plasticizer, glaze suspending agent and dye-fixing agent. Sodium Carboxymethylcellulose can also be used in construction works. For example, in concrete construction, adding Sodium Carboxymethylcellulose can reduce water loss and has an effect on delayed coagulation, so it is not only convenient for large-scale construction, but also can enhance the strength of structures.
Sodium Carboxymethylcellulose is odorless, tasteless, non-toxic, easily soluble and won’t get bad for long-term storage. Moreover, it has high viscosity and strong shape-preserving capacity, so is widely used in the food industry.
For example, it can act as the extender of adhesive agent in the process of jam, sugar, fruit syrup and pungent sauce. In dessert, it enables the tissue to be homogeneous and fine, the appearance beautiful. It can also be used as the stabilizing agent in the production of ice cream. It can function as the shape fixing agent in the production of lemon and grape drinks as well as semi-fluid edible oil and fat apt to rancidity. Furthermore, it can be used as the film forming agent in the surface treatment of vegetables, fruit, eggs and tea leaves to keep the original color and flavor for long.
3. Microcrystalline Cellulose Application in Pharmaceutical Industry
In the pharmaceutical industry, Microcrystalline Cellulose can be used as emulsion stabilizer of various kinds of injections such as penicillin and streptomycin. Moreover, it can act as the basic material of various kinds of emulsifiable paste, the adhesion agent of tablets as well as the dispersing agent of barium sulfate and titanium oxide in X-ray vision. It can also be used to fix teeth and to make aperient, styptic, adhesive and contraceptive.
4. Application in Daily Chemical Industry and Other Industries
In toothpaste, body cream and shampoo, Sodium Carboxymethylcellulose can act as the stabilizing and emulsifying agents to regulate viscosity, stabilize foam, enhance cleansing power and produce fine, smooth quality. Sodium Carboxymethylcellulose is also an ideal adhesive agent in the production of mosquito coils, footwear uppers, paper boxes, pencils and reconstituted tobacco.
In addition, hydroxypropyl methylcellulose can also be used as the glazing and coloring agents of leather, surface treatment agent of filmstrip and photo negative film, stabilizing agent of rubber paste, foam stabilizer of fire foam, and dispersing, stabilizing as well as emulsifying agents in pesticide and plastic industries.
In the coating industry, it can act as the sizing agent or regulate viscosity. In the production and storage of formaldehyde, it can act as the polymerization inhibitor. Moreover, hydroxypropyl methylcellulose can also be used in shipping, electron tube, floating separation, welding electrode, refrigerated storage of aquatic products and metal processing. It can act as thickener for civil use.
All in all, Cellulose Ether is widely used, highly adaptable, and not only an essential basic material as well as auxiliary material in many industries, but also the substitute for grain of industrial use, so it occupies an important position in the nation economy.
