What is the function of boric acid

Boric acid is a weak acid. It is widely used in various fields such as medicine and chemical industry. For example, it is often used as an antibacterial agent and often used to treat infant skin eczema. Boric acid is also often used in cosmetics. When using boric acid, you must understand some precautions, especially when using it as a medical treatment, to avoid some side effects.

Function and use

It is often used as a cold wet compress, which has anti-inflammatory, detumescent, antibacterial, astringent and wound cleaning effects. It is suitable for acute dermatitis and eczema with redness, swelling or erosion accompanied by secondary infection and excessive exudation.

After U-235 undergoes fission reaction, fast neutrons are produced. The fast neutrons move in the moderator, their energy gradually decays, and finally turn into thermal neutrons. This period of time is called the moderation time, and this process is called the moderation process. After a fast neutron becomes a thermal neutron, it may not be absorbed immediately. It will move for a period of time before being absorbed. This period of time is called the diffusion time. During the moderation process, a moderator may be used. The function of the moderator is to slow down neutrons so that they can easily react with the target nucleus. The prerequisite for being a moderator is that it has a large scattering cross section and a small absorption cross section, so that the moderation effect is good. The best moderator is heavy water, as well as carbon dioxide, carbon, water, boron-10 isotope, etc.

usage

Take 4 to 6 layers of gauze, soak them in the solution, and then use tweezers to gently wring them until no water drips. Apply the wet gauze to the affected area, and rewet the gauze every 5 minutes for about half an hour. 2 to 3 times a day.

Precautions

①The temperature of the solution used cannot be higher than room temperature. ②The moist gauze should be replaced regularly to maintain appropriate temperature, humidity and sterility. ③ When the skin lesions are large, especially when there is erosion, it is not suitable to use this medicine for wet compresses, so as to avoid toxic reactions such as vomiting, diarrhea, convulsions, lethargy, blindness and kidney damage caused by large-scale absorption of boric acid. It is advisable to use 1:8,000 potassium permanganate solution for wet compresses instead. When there is no infection on the lesion, you can apply normal saline solution for wet compress. ④ When the weather is cold, you should keep warm when applying wet compress.
