Description
Technical field
The present invention relates to a kind of preparation methods of safe and efficient color bleaching liquor, belong to daily chemical product technical field.
Background technique
In daily life, the clothing of people be often infected with because of a variety of causes various spots (such as
Tea stain, fruit and vegetable stain etc.), however, people, which usually can select, has bleaching effect in order to be effectively removed the various spots on clothing
Remaining spot on detergent (such as chemical bleaching agent) Lai Qingjie clothing of fruit.
Generally, chemical bleaching agent divides two major classes, i.e. color bleaching liquor containing chlorine and oxygen-containing color bleaching liquor.The bleaching effect of color bleaching liquor containing chlorine is not
Mistake, but damage or decolourization are easy to produce for silk goods, wool product and some coloured fabrics, while having to hand skin
Biggish injury, so its use scope is restricted.Current oxygen-containing color bleaching liquor gradually substitutes color bleaching liquor containing chlorine.
And oxygen-containing color bleaching liquor, bleaching can be played when it releases active oxygen, goes the effects of stain, degerming, with various laundries
When powder is used cooperatively, the release of active oxygen can be promoted.Oxygen-bearing bleaching agent has been the functional raw material of blanching effect, predominantly peroxide
Change hydrogen.Hydrogen peroxide is a kind of unstable compound, water and oxygen is easily dispersed under the induction of certain factors, to influence
Functional result.
Color bleaching liquor category oxygen-bearing bleaching agent, pH value are acidity, and bleaching can be played when it releases active oxygen, goes stain, degerming
The effects of, therefore, be widely used in family, hotel, laundry factory, hospital and public institution's fabric go stain, brighten, increase it is gorgeous.
But the active oxygen in color bleaching liquor is unstable, in storage and transportational process, due to being irradiated by sunlight, shaking the factors such as dynamic friction
Influence, active oxygen, which is extremely easy in decomposition, to be released, cause color bleaching liquor go stain, brighten or increase it is gorgeous less able, even
Failure.
As it can be seen that existing oxygen-containing color bleaching agent is good there are oxygen content stability but oxygen content is not high or oxygen content is higher
But it is poor containing oxidative stability, so as to cause the ineffective problem of its rinsing.
Summary of the invention
The technical problems to be solved by the invention: it is unstable for the active oxygen in oxygen-containing color bleaching liquor, it is storing and is transporting
In the process, it is influenced since the factors such as dynamic friction are irradiated, shaken by sunlight, active oxygen, which is extremely easy in decomposition, to be released, and color drift is caused
