Principle of soap decontamination

Decontamination principle of soap: The molecular structure of soap can be divided into two parts.

Chief operating officer of charged polarity-(hydrophilic site);

Nonpolar carbon chain (lipophilic site). Soap can break the surface tension of water. When soap molecules enter water, the hydrophilic part with polarity will destroy the attraction between water molecules, reduce the surface tension of water, and make water molecules almost evenly distributed on the surface of clothes or skin to be cleaned.

The deodorization principle of stainless steel soap is basically decomposed. When stainless steel alloy comes into contact with air and water molecules at the same time, it will produce catalysis, decompose the molecular structure of odor and "reduce" it to a tasteless state. The matte surface of specially polished stainless steel rubs against the object, and the released iron ions combine with odor molecules to achieve the effect of odor removal. Stainless steel soap is usually "half put in water and half exposed to air". When it is used for the first time, it takes 5 -6 hours to work normally. The effective use time can be maintained for 3-5 years.

Ordinary soap, the main components are sodium and potassium salts of higher fatty acids. Some molecules of these salts are soluble in water and are called "hydrophilic groups"; The other part is insoluble in water and soluble in oil, which is called "lipophilic".

After oil stains and other substances are surrounded by soap molecules and water molecules, the adhesion to clothing fibers decreases. Once cleaned, soap liquid permeates into different amounts of air and produces a lot of foam. There seems to be a layer of tension film on the surface of foam, which not only expands the surface area of soap solution, but also makes soap solution more contractible, usually called surface tension. Under the action of surface tension, oil stains, dust and other particles on clothes are easily separated from clothes and go with water. This is the secret that soap can decontaminate.
