Sodium Polyacrylate is a kind of high molecular compound with hydrophilic group. It appears odorless and tasteless white powder. It will form transparent solution of great viscosity while slowly dissolved into water. The viscosity of 0.5% solution is about 1000cp. The viscosity is engendered by the dissociation of numerous anions and hence causes the growth of molecular chain not by expansion of water absorption that normally happens to CMC and sodium alginate. The viscidity is about 15-20 times higher than carboxymethyl cellulose sodium and sodium alginate. It shows high alkali-resistant, minor change in viscosity after longtime storage, and not easily decaying.
Usage and Notes:
Dissolution Method: rapid mixing, adding sodium polyacrylate powder slowly and evenly. Slowly add in sodium polyacrylate while stirring with water.(Pay attention: Do not add a large number of powder and sprinkle the powder into water instead of pouring into, otherwise it will generate half-cooked micelle, it is difficult for dissolving, stirring for 10 minutes, static 3 hours that is completely dissolved. It’s better to keep warm and stirring the solution to become well-distributed solution, solution concentration is about 0.1%-0.5%, dissolve time is about half hour) (Mixture ratio: 1KG sodium polyacrylate per 1 cubic) (1g/L water) Users can adjust the test according to addition and experiment.
Reference dosage: General usage—0.2%
Mainly application area:
(1) food manufacturing sodium polyacrylate could use for thickening: emulsification, figuration, swelling, steady, the viscosity is 15-20 times higher than carboxymethyl cellulose sodium and sodium alginate can replace the role of CMC, gelatin, agar, sodium alginate and reduce costs, increase food grade, improve the taste and extend the retention period; as the thickener, it can be use for many kinds of food, the addition we s ested is 0.1%-0.2%
The following are examples:
a. Noodle Industry Flour products like instant noodle, noodle, various types of flour, bakery food and so on. Enhance the protein cohesive force of flour, prevent the soluble starch and nutrients emulative, improve dough extensibility and raw material utilization. To improve the taste and flavors, control of dry bread and other food products caused by natural drying. In the deep-fried food processing, like instant noodle, to spread fat of raw materials steady in dough, decrease oil absorption rate and save oil.
b. Beverage Industry As a compound emulsion stabilizer ingredient components, replace the role of CMC gelatin, agar and so on, play enhancement effect and reduce the cost.
c. Meat Factory It can be used in the manufacture of artificial meat, enhance the viscoelasticity and extensions for protein fiber, increase sensuality and reduce cost.
d. others
(2) Cosmetics Manufacturing
Sodium Polyacrylate Act a part in inspissate, disperse, suspend, steady and so on in cosmetics. It’s in favor of thickening, froth, steady, emulsification, disperse, conglutinate, film forming and moisture retention in cosmetics’.
(3) Toothpaste Manufacturing
Sodium polyacrylate can make toothpaste more sticky obviously and easy to shape. It looks sharp and smooth, paste delicate have some function like keep moisture wash well and stand fire.
(4) Tobacco Manufacturing
Sodium Polyacrylate can be use for binding tobacco sheet have some effect on reduce the cost. In addition, it also can be use as binder of cigarette paper.
(5) Pharmaceutical Manufacturing
Sodium Polyacrylate can be use in pharmaceutical Industry as drug pulp thickener, stabilizing agent, mix water preparation and ointment drugs.
