What is Sodium Polyacrylic Acid?

Sodium Polyacrylic Acid is a white powder. Odorless and tasteless. Really hygroscopic. Polymer substances with hydrophilic as well as hydrophobic groups. It slowly liquifies in water to create an extremely viscous transparent fluid. The viscosity of its 0.5% service has to do with · s. The ionic sensation makes the molecular chain expand, as well as the apparent viscosity boosts to create a very thick remedy.Its density has to do with 15-20 times that of CMC and also salt alginate. Warm treatment, neutral salts, and also organic acids have little effect on its thickness, yet the viscosity raises when it is alkaline.Insoluble in natural solvents such as ethanol. Strong heat to 300 degrees does not disintegrate. The long-lasting thickness adjustments extremely bit, and also it is not easy to be corrupted. Due to the fact that it is an electrolyte, it is conveniently influenced by acids as well as steel ions, and its viscosity reduces. In case of steel ions with greater than two valences.

Sodium Polyacrylic Acid Uses

  1. Sodium Polyacrylic Acid is a synthetic polymer utilized in cosmetics and also skin therapy items. Made use of to enhance the sensory feeling as well as likewise safety of the product. Utilized as thickener, texture booster, motion picture previous along with emulsion stabilizer.
  2. Sodium Polyacrylic Acid is utilized for flowing cold water therapy of copper devices, and its range inhibition outcome is good. When the dose is 100 mg/L, it can create chelate facilities with scale-forming ions in tool firmness water in addition to circulation with the water, along with can stop the development of iron oxide range.
  3. Sodium Polyacrylic Acid has the list below impacts in food:
    ( 1) Enhance the healthy protein communication in raw flour.
    ( 2) Make the starch particles incorporate with each other, disperse and also permeate right into the network structure of the protein.
    ( 3) Kind a dense dough with a smooth and also shiny surface.
    ( 4) Form a steady dough colloid to avoid oozing out of soluble starch.
    ( 5) Solid water retention, to ensure that the water is equally kept in the dough to prevent drying.
    ( 6) Enhance the extensibility of dough.
    ( 7) Make the oil components in the raw products distribute stably into the dough.
    2. Sodium Polyacrylic Acid serves as an electrolyte to engage with protein, transform the healthy protein framework, enhance the viscoelasticity of food, and also enhance cells.
    3. Application instance:
    ( 1) Bread, cakes, noodles, macaroni, raise the use rate of raw materials, enhance the preference and flavor. Dose 0.05%.
    ( 2) Marine minced products, canned food, dried out seaweed, and so on, enhance the cells, maintain freshness, and also boost the sense of taste
    ( 3) Sauce, tomato sauce, mayonnaise, jam, lotion, soy sauce, thickener as well as stabilizer.
    ( 4) Juice, a glass of wine, and so on, dispersant.
    ( 5) Ice cream and sugar candy boost taste as well as stability.
    ( 6) Frozen food, refined aquatic products, surface area jelly (fresh conservation).
    4. Since Sodium Polyacrylic Acid dissolves gradually in water, it can be combined with granulated sugar, powdered starch syrup, emulsifier, and so on ahead of time to boost the dissolution price.
    5. Sodium Polyacrylic Acid is made use of as a making clear representative (polymer coagulant) for sugar liquid, seawater, beverages, and so on. Aquatic handling rock recuperation of healthy protein in wastewater; and also purification of wastewater

Commonly used dispersants - Sodium Polyacrylic Acid

The molecular mass of Sodium Polyacrylic Acid used as a dispersant is generally controlled at 3000-5000. It is a water-soluble polymer polyelectrolyte. When Sodium Polyacrylic Acid is dissolved in water, it is ionized in water, and the degree of ionization is large, forming a polymer Anions and many small molecular ions (Na+). Polymer anions and small molecular ions are firmly adsorbed on the surface of the dispersed particles, so that the ions have the same charge, and the oppositely charged ions (Na+) freely diffuse into the surrounding liquid medium, forming a stable diffusion layer of charged ions , the electric double layer. Since the ions with the same charge repel each other, the formation of electrostatic repulsion can prevent particles such as pigments from flocculating in the aqueous medium, so as to achieve the purpose of dispersion. At the same time, due to the steric hindrance effect of the polymer, it can also prevent the particles doing Brownian motion from approaching, resulting in composite stabilization.

If, when the molecular weight of Sodium Polyacrylic Acid is relatively large (above 104), the excessively long molecular chain will cause the particles to become larger and precipitate through bridging between the particles. At the same time, the negative charge of the acid radical on the macromolecular chain is combined with the particles in the water through adsorption, so that flocculation occurs between the particles due to aggregation. This is also the mechanism of action of the large molecular weight Sodium Polyacrylic Acid as a flocculant. Therefore, polyacrylic acid It is very important to control the molecular weight of sodium, otherwise it will have a completely different effect.

Basic properties of Sodium Polyacrylic Acid as a Dispersant

1 Chemical stability
Sodium Polyacrylic Acid is a colorless or light yellow point thick liquid with good thermal stability. It does not decompose when heated to 300°C, and it is extremely stable even after high temperature treatment. Therefore, for the wet grinding slurry with PAAS added, the PAAS adsorbed on the surface will not be decomposed after drying and dehydration.

2 Hygroscopicity
Sodium Polyacrylic Acid is a polymer electrolyte, and there are a large number of strong hydrophilic groups (-COONa) connected in the molecular chain, so it is extremely hygroscopic. In the air, the dry product can absorb moisture up to 1.1 times its own weight (high molecular weight PAAS). It can be seen that when PAAS is added in the production process, the hygroscopicity of the product increases, that is, the product is more susceptible to moisture, so moisture-proof treatment should be paid attention to during packaging and storage.
