Aluminum Sulfate Functions
On the function of alum
Alum, the chemical name is aluminum potassium sulfate, which is quite useful in all things in life.
The power of water purification
One is the purification of water, and the effect is obvious. Water has turbid matter, and when alum enters it, it will become wonderful. It dissociates in contact with water, and aluminum ions are hydrolyzed to produce an aluminum hydroxide colloid. This colloid has strong adsorption, and the sediment and impurities suspended in the water are all attached to it, and gradually settle, making the water turn from turbid to clear. In the past, the water of the well spring in Murano was occasionally turbid, and the ancestors threw a little alum into it. After waiting for a while, the water was clear and drinkable. This is the power of alum water purification.
The use of papermaking
Second, it is also indispensable in papermaking. When making paper, in the pulp, alum can be used as a sizing aid. It can be combined with paper fibers to form a protective film on the surface of the paper and enhance the water resistance of the paper. In this way, the ink is written on it, so that it will not be scattered, and the handwriting is clear and legible. The ancient calligraphy and painting paper relies on the help of alum to last for thousands of years and the ink rhyme will remain for future generations to appreciate.
The help of food processing
Third, it is also useful in food processing. For example, when frying fritters, alum and baking soda are used together. When the two meet, a chemical reaction occurs, producing a large amount of carbon dioxide gas. This gas expands in the dough, causing the fritters to rapidly foam and expand, making them crispy and delicious. However, it is suitable for use, and excessive amounts are harmful to the human body. Therefore, in today's food processing, the dosage is strictly regulated.
Effect in the field of medicine
Fourth, it is also effective in the field of medicine. Alum has the ability to converge, dry and wet, detoxify and kill insects. External use can treat eczema itching, sore scabies and other diseases. If the skin is ringworm, use alum to grind the end, adjust the water and apply it, it can dry and relieve itching, and insecticide and treat ringworm. Internal use can prevent vomiting and diarrhea, but toxicity also exists, and the dosage should be used with caution.
Although alum is small, it is useful in all aspects of life. Those who use it should know its nature, use it reasonably, and then they can promote its strengths and avoid its weaknesses, for the benefit of people.
