Hydrogen Peroxide Bleaching Ability
On the Bleaching Effect of Hydrogen Peroxide
The world is called hydrogen peroxide, which has unique properties and is quite effective in bleaching.
Hydrogen peroxide, with the characteristics of the reactive oxygen species it contains, can interact with many chromophores. The color development of the color covering quality has a specific chromophores in the structure. When hydrogen peroxide encounters it, its oxidizing properties will break the structure of the chromophores, causing its color to become lighter or even disappear. This is the fundamental reason for its bleaching.
The stain of the fabric is obvious due to dust or stains. Applying hydrogen peroxide can make the fabric white again. In the genus of cotton and linen, it can penetrate deep into the fiber gap, remove the color quality hidden in it, and do not damage the toughness of the fiber, so after bleaching, the fabric still retains a soft and comfortable quality. In silk and the like, it can also be done with caution to remove the color without damaging its delicate luster, so that the silk is still warm and moist as before.
Furthermore, yellowing of paper is also a common situation. As the years pass, the lignin and other components in the paper oxidize and change color. If you wipe it lightly with hydrogen peroxide, the oxidized color quality can be restored, making the paper smooth again. When ancient books are restored, this technique is particularly crucial. It can restore the original appearance of ancient books and make the words of the past clear as before. It is of great service to cultural inheritance.
However, the bleaching of hydrogen peroxide also needs to be well controlled. If the concentration is too high, although the bleaching speed is fast, it will be vulnerable to the bleached material. Such as fabric or fiber embrittlement, paper or strength reduction. And its reaction is restricted by factors such as temperature and time. If the temperature is high, the reaction speed will be high, and if it is too high, it will cause runaway; if it is bleached for a long time, it will not hurt the main body.
Therefore, those who use it should carefully observe the physical properties and precisely control all conditions, so that the bleaching ability of hydrogen peroxide can be fully exerted, and the ideal effect can be obtained without damaging the used material.
