Alginate,
also known as sodium alginate, seaweed gum, algin, alginate, a natural polysaccharide extracted from seaweed in carbohydrates. Description: White or light yellow, vagiform power, odorless, tasteless, dissolve in water, insoluable in ethanol and ether.
Widely used in food, medicine, textile, printing and dyeing, paper making, daily chemical products such as thickeners, emulsifiers, stabilizers, binders, sizing, etc. use.
1. In printing and textile industry.
a. Printing agent (sodium alginate for reactive printing,the viscosity from 50-1500cps )
b. Synthetic fibre
Mix Sodium Alginate and asbestos shon fibre, then mixture solidify the by a solution of Calcium Acetate. This treatment can avoid Asbestos fibre of flying around to harm to health.
2.In other industry
Papermaking starching: When using the solution of Sodium Alginate replacing pan of Rosin as dispering agent of paper pulp of paper surface starching, it can make paper glooss and smooth, raise the absorption of printing ink, wax, soil and paper's pliability and tough.
Coating of the welding electrode:
The mixture of welding - coating powder and Sodium Alginate can stick and humify the coating of welding and make it easy to burn into ash and lighten flying during welding operation. In addition , Sodium Alginate can also apply to disposing of seeds, pesticide, antitoxin and antibitic.
3. In food industry
a: Stabilizer
b: Thickener and emulsion
c: Hydration
d: Coacervation
4.In medical industry
a. dental impression material
b. Hemostatic
The solution of Sodium Alginate will have a wadding sediment, which molecular structure is like thread. Making use of this mechanism, Sodium Alginate can be made into all kinds of hemostatic, such as hemostic gauze, hemostic cotton, scald gauze, spraying hemostatic, ect.
c. Preventing and exclusion from radioactive harmful metals
d. Salve, tablet and drugs
Using of the thickener and coacervation, Sodium Alginate can be made into all kinds of additive of medicines, such as Sulphur Paste mixed by Sodium Alginate and wool oil which can treat skin disease.
