What role does emulsifier S-80 play in metallurgical beneficiation?

Emulsifier S-80 can promote two immiscible liquids to form the surfactant of stable emulsion. The emulsifier S-80 can reduce the surface tension of the dispersed phase, and form a film or a double electric layer on the surface of the droplet, which does not make the droplets agglomerate with each other, but forms the emulsion in the medium. The function of emulsifier S-80 is usually indicated by the balance of hydrophilicity and lipophilicity (HLB). Emulsifier S-80 can be divided into two types: oleophilic type (i.e. water in oil type w / O) and hydrophilic type (i.e. oil in water type O / W). The former (such as monostearate glyceride, etc.) can make water disperse into oil, and the latter (such as soybean phospholipid, sucrose ester, etc.) can make oil disperse into water.

Emulsifier S-80 used in mineral processing and metallurgy includes high-grade fatty acid soap, polyol sulfuric acid ester, petroleum sulfonic acid and sulfonate, polyol phosphate, quaternary ammonium salt, etc.

In the flotation process, for the reagents that are difficult to dissolve in water, or in order to reduce the dosage, the emulsifier S-80 is usually added first to fully emulsify the reagents (such as collectors) to make them loose in water, to form the emulsion like oil beads, to increase the external volume of the reagents, to increase the contact opportunities between the reagents and the mineral particles, and then to greatly reduce the dosage of flotation reagents, shorten the flotation time and progress Flotation efficiency. In general, when using fatty acids and aliphatic amines as collectors, adding emulsifier S-80 can improve their collection function and selection function. For example, it can reduce the adsorption effect of clay or slime in pulp on collectors such as fatty acid soap and amine salt, and improve the collection ability and selectivity of reagents for useful minerals.

In the flotation process of rare mineral deposits, the amount of collector can be reduced by using the emulsion as collector, barite and fluorite as collector, and fatty acid emulsion as collector. There are many kinds of emulsifiers S-80, which are widely used in medicine, synthetic rubber, synthetic resin, leather, cosmetics, pesticides, food and other industries besides flotation and the manufacture of some reagents.

What is the significant role of emulsifier S-80 in ice cream?

In the ice cream we often eat, the emulsifier S-80 was added, so the ice cream can adhere to a variety of shapes. So why should we add emulsifier S-80? How does emulsifier S-80 stick to the shape of ice cream? Let's explain the effect of emulsifier S-80 in ice cream:

Ice cream is a kind of frozen dairy products, which belongs to solid cold food. With its rich nutrition and common taste, ice cream is welcomed by broad consumers. The mixing formula of ice cream and the frozen processing conditions are the important factors to make delicious ice cream, but the effect of emulsifier S-80 is also the key factor. The increase of emulsifier S-80 in ice cream is generally 0.1% - 0.4%. The effect can be summarized as follows:

1. Improve the dispersibility of fat in the mixed guessing, make the fat particles fine and evenly distributed, and improve the stability of emulsion.

2. It can promote the interaction between fat and protein, make the emulsion break steadily, and help to control the agglomeration and agglomeration effect of fat.

3. Improve air mixing and foaming ability.

4. Avoid and control the formation of coarse ice crystals, and improve the heat resistance of ice cream.

5. Avoid shrinkage and deformation during storage, and improve oral fusion.
