Hydrogen peroxide stabilizer

Hydrogen peroxide stabilizer


Oxygen peroxide is generally used in alkaline medium in the one-bath process of oxygen bleaching or retreating, boiling and bleaching. Hydrogen peroxide is relatively stable under weak acid or neutral conditions, and is activated under alkaline conditions, with strong oxidation. The presence of heavy metal ions causes premature catalytic decomposition of hydrogen peroxide, which not only causes the failure of bleaching solution, but also causes fiber damage.

Therefore, in order to control the decomposition of hydrogen peroxide in the oxygen bleaching or deboil bleaching process, avoid fiber damage, and get good bleaching effect, in addition to should control the pH value of bleaching solution, but also need to add to slow down the decomposition rate of hydrogen peroxide additives, this prevent hydrogen peroxide uncontrolled decomposition of the added additives called hydrogen peroxide stabilizer.

Product name: Hydrogen peroxide stabilizer
Chemical formula: H2O2
Product name: Hydrogen peroxide stabilizer

H2O2 is a classic chemical products, hydrogen peroxide bleaching agent because of its good stability, no equipment corrosion, no pollution, and is widely used for cellulose fiber and other fiber bleaching, it is a kind of excellent bleaching agent, product whiteness, good stability for the environment pollution-free, thus has been used and very promising bleach.

In the bleaching process, if the decomposition of H2O2 is not controlled, the waste of H2O2 will result. "Whiteness difference", "fiber strength decline", bleached cloth appeared holes.

In order to decompose hydrogen peroxide evenly and effectively during bleaching and avoid severe damage to fabric, a certain amount of stabilizer must be added into bleaching solution.

According to its chemical composition, oxygen drift stabilizer can be divided into two kinds: containing silicon and non-silicon. According to the mechanism of their stabilizing function, they can be divided into two types: adsorption type and chelation type. In fact, both functions are present in oxygen bleaching stabilizers, but with different emphasis.

There is a solid type H2O2 non-silicon stabilizer EM-88 successfully developed by Changzhou Institute of Printing and Dyeing Science in China. It is developed on the basis of solid type H202 non-silicon stabilizer EMP. Good alkalinity resistance and bright fabric luster. The stabilizers produced abroad include: Lustabil V developed by Hearst Company, Germany, Prestogen-EB, PC, K oxygen bleach stabilizer developed by BASF Company, Germany, and Lastabil-K 1095 developed by Hoechst Company, Germany.

Along with the advancement of national energy conservation and emission reduction policy, at the present stage of hydrogen peroxide bleaching have begun to have low temperature bleaching processes, such as textile practice bleaching process, the low temperature of 80 degrees in the low temperature bleaching technology practice, also need to join the activation of special - stability related material, suitable for low temperature under the condition of hydrogen peroxide stabilizer is also the direction of future research and development.
