Product features:
Strong hydrophilicity, in cold water and warm water can be dissolved, forming a solution even very viscous.
True solution formed with other analogues are difficult to obtain flexibility, uniformity and other excellent characteristics.
Has a strong function of the protective colloid, emulsion capacity on oil strong.
Adding aluminum, barium, calcium, copper, iron, lead, zinc, nickel and other metal salts in solution, it will generate insoluble alginate. These metal salts is the sodium, potassium phosphate,
acetate buffer, etc., can inhibit the delayed solidification.
Usually, the pH value is 7, neutral, can be adjusted between 4-10.
Is a linear polymer electrolyte, can be made of strong fibers (alginate fiber) or film, is to prevent cracking effect. Adhesive small, suitable for warp sizing, demoulding.
Uses:
used in industry, textile sizing agent and printing paste; in medicine, used to increase blood volume and maintain blood pressure, eliminate burn produced by histamine toxoid and trauma hemorrhage,
operation before and after the cycle of system stability, a lot of hemorrhagic shock, burn shock, fever and other systemic acute dysentery dehydration, good therapeutic effect. Also has makes
cholesterol excreted, inhibition of Pb, Cd, Sr is absorbed by the human body and the protection of the gastrointestinal tract, intestines, lose weight, the effect of reducing blood sugar.
The medicine is mainly used as a suspending agent, emulsifier, viscous agent, microcapsules encapsulating material and so on; used as a stabilizer in food industry,; thickener; emulsifier;
dispersant; gelling agent; coating agent; suspension.
