fire extinguishing agent

The foam extinguisher contains about 1 mol/L alum solution and about 1 mol/L NaHCO3(Baking soda) solution (with foaming agent), the volume ratio of the two solutions is about 11:2. Excessive alum is used to fully react the baking soda in the fire extinguisher, releasing sufficient carbon dioxide to achieve the purpose of extinguishing the fire.

Buffering agent

It can be used as a buffering agent in sulfate zinc plating to stabilize the pH value of the plating solution. Aluminum potassium sulfate is used for sulfate zinc plating, brush zinc plating, and chemical oxidation of magnesium alloys. It can also be used as a coagulant for treating wastewater. If used for zinc plating, attention should be paid to its iron and heavy metal content.

water purifying agent

Adding 750 mg of alum to one liter of water has a purifying and sterilizing effect. Different amounts of water added to turbid river water can affect its clarity. Alum water purification is a method commonly used by the public in the past. Its principle is that alum can ionize two metal ions in water, while Al3+Easy to hydrolyze, producing aluminum hydroxide Al (OH)3Colloids, such as aluminum hydroxide colloids, have strong adsorption capacity and can adsorb suspended impurities in water, forming precipitates and clarifying the water. So, alum is a highly effective water purifying agent. But the aluminum contained in alum is harmful to the human body. Long term consumption of alum purified water may cause Alzheimer's disease, so it is not recommended to use alum as a water purifier .

Phase change thermal storage material

Potassium aluminum sulfate dodecahydrate has the advantages of high latent heat of phase change, low cost, and safety and non toxicity. It is an abundant source of low-temperature inorganic hydrate salt phase change thermal storage material. Preparing it into eutectic or non eutectic composite phase change materials can reduce the phase change temperature, and therefore can be widely used in fields such as valley electricity thermal storage, building heating, product energy conservation, solar thermal utilization, and battery thermal management.

medical field

Alum has a cold and sour taste, and has a strong astringent effect. Traditional Chinese medicine believes that alum has the effects of detoxifying and insecticidal substances, relieving dampness and itching, stopping bleeding and diarrhea, clearing heat and eliminating phlegm, as well as anti vaginal trichomonas. Some traditional Chinese medicine uses alum to treat diseases such as hyperlipidemia, duodenal ulcer, pulmonary tuberculosis hemoptysis, etc.

Food sectorPotassium alum ammonium alum manufacturer

Expanding agent: When frying deep-fried dough sticks (cakes) or puffing food, if baking soda is added to the flour and then alum is added, the production of carbon dioxide will be accelerated, greatly accelerating the expansion speed. In this way, deep-fried dough sticks (cakes) can be quickly inflated and fluffy in the hot oil pan. Potassium alum ammonium alum manufacturer
