Produkteinführung:

Potassium nitrate is an white powder that does not deliquesce in the air. Sometimes it is light gray due to impurities. The density is 2.11g / cm3, which melts at 3334℃ and is higher than 338℃. It decomposes into potassium nitrite and releases oxygen. The solubility of potassium nitrate decreases with the increase of nitric acid concentration, and then increases when it reaches the lowest value; the solubility of potassium nitrate in water increases with the increase of temperature. The pure product contains 46.58% potassium oxide and 13.85% nitrogen. Potassium nitrate is easily soluble in water, and its solubility increases sharply with increasing temperature. It can dissolve 31.2 grams per 100 grams of water at 20 °C and 247 grams at 100 °C.

Spezifikation

Anwendung:

1. Used as analytical reagents and oxidants, but also for the synthesis of potassium salts and the preparation of explosives.

2. Used as a coloring agent, color protecting agent, antimicrobial agent, and preservative in the food industry. For example, it is used in cured meat to play a preservative role in lunch meat.

3. It is the raw material for manufacturing black gunpowder, such as mine gunpowder, fuse, firecracker, etc. Also used for fireworks to produce purple sparks. Mechanical heat treatment is used to quench the salt bath. The ceramic industry is used to manufacture enamel color medicine. Used as glass clarifier. Used in the manufacture of automobile lamp bulbs, optical glass kinescope bulbs, etc. The pharmaceutical industry is used to produce penicillin potassium salt and rifampin medicine. Used for making cigarette paper. Used as a catalyst. Mineral dressing agent. Used as compound fertilizer for crops and flowers.

4. Potassium nitrate is also a coloring agent allowed in China.

5. Used for making fireworks, matches, ceramic glaze, fertilizers, etc.

6. Industrial potassium nitrate is also widely used in the manufacturing process of strengthened glass.

Produktionsdetail:

Using ion exchange resin or zeolite, using potassium chloride and nitrate as raw materials, according to the characteristics of the cation exchange resin & #39;s close adsorption of potassium ammonium ions, using the role of cation exchange resin to make potassium chloride and potassium in nitrate solution Ammonium ions are converted into each other on the ion exchange resin to obtain potassium nitrate solution.
