As a common inorganic chemical, aluminum hydroxide is a white powdery substance that is weakly alkaline. Aluminum hydroxide has a variety of important uses, the following will be from the industrial, medical and daily life three aspects to introduce its application and its importance.

1. industrial applications

aluminum hydroxide has important applications in industry, the most important of which is as an important aluminum raw material. Since aluminum hydroxide is relatively stable and not easily dissolved, it is not easily affected by foreign substances during the purification process. In addition, it is also widely used in industries such as paint, coatings, plastics, paper and leather. For example, aluminum hydroxide can be used as a binder and thickener in the production of coatings and paints. In the leather industry, aluminum hydroxide can be used as a tanning agent to help leather shrink and harden, resulting in a firmer and stronger cortex.

2. medical applications

aluminum hydroxide is also a very important chemical in medicine. Clinicians often use aluminum hydroxide to treat digestive tract diseases, such as gastric ulcers, gastroesophageal reflux disease and indigestion. This is because aluminum hydroxide can neutralize stomach acid, thereby relieving inflammation and pain in the gastrointestinal tract.

In addition, aluminum hydroxide can also be used to treat skin diseases such as impetigo and eczema. Studies have shown that aluminum hydroxide can effectively inhibit the growth of bacteria on the skin surface, and it can also reduce pain and itching in patients.

3.

in everyday life In addition to industrial and medical applications, aluminum hydroxide is also a useful substance in everyday life. The most typical application is as an antiperspirant. A large number of studies have found that aluminum hydroxide can effectively inhibit the secretion of sweat glands, thereby reducing people's sweating problems.

Furthermore, in the field of cosmetics, aluminum hydroxide can be used as an oil-absorbing powder. Because it can play a refreshing and oil-controlling role, it is often added to some foundations, concealers and facial cleansers.
