Application area



extinguishant
Foam extinguisher contains about 1mol/L alum solution and about 1mol/L NaHCO3 (baking soda) solution (with foaming agent), and the volume ratio of the two solutions is about 11: 2. Alum excess is to make the baking soda in the fire extinguisher fully react and release enough carbon dioxide to extinguish the fire.
swelling agent
When frying fried dough sticks (cakes) or puffing food, if baking soda is added to flour and alum is added, the production of carbon dioxide will be accelerated and the puffing speed will be greatly accelerated. In this way, the fried dough sticks (cakes) can be bulged in the hot oil pan at once, and the crispy and delicious fried dough sticks (cakes) can be obtained.
buffering agent
It can be used as a buffer in sulfate zinc plating to stabilize the ph value of the plating solution. Potassium sulfate is used for sulfate zinc plating, brush zinc plating and chemical oxidation of magnesium alloy, and can also be used as coagulant for sewage treatment. If it is used for zinc plating, attention should be paid to its iron and heavy metal content.
Medical field
Alum is cold and sour, and has a strong astringent effect. According to Chinese medicine, alum has the effects of detoxifying and killing insects, eliminating dampness and itching, stopping bleeding and diarrhea, clearing away heat and eliminating phlegm, and resisting trichomonas vaginalis. Some Chinese medicine practitioners use alum to treat diseases such as hyperlipidemia, duodenal ulcer, tuberculosis and hemoptysis.
Food field
Alum can also be used to cook mung bean porridge. Its main function is to make mung beans more easily boiled, but this is not recommended because it is difficult to control the dosage and may be poisoned. It can be replaced by edible alkali.
