Abstract
The invention provides a method used for treating mildewy polycarboxylic acid superplasticizers with hydrogen peroxide. The method comprises the following steps: putting the mildewy polycarboxylic acid superplasticizers in a corrosion resistant container; adding hydrogen peroxide to the corrosion resistant container and fully stirring the materials. Tests show that after the mildewy polycarboxylic acid superplasticizers are treated by the method, the original properties of the mildewy polycarboxylic acid superplasticizers can be restored, the colors are close to the colors of the original products and the peculiar smell can be eliminated.
Description
Technical field
The present invention relates to material of construction processing technology field, particularly a kind of hydrogen peroxide treatment process for the polycarboxylic acid series high efficiency water reducing agent that goes mouldy.
Background technology
Building concrete high-efficiency water-reducing agent of poly-carboxylic acid is a kind of organic polymer chemical additive.Product easily goes mouldy under high temperature, wet vexed environment, is gone bad as not only black but also smelly by colourless or light brown.Water-reducing rate declines, and has a strong impact on result of use and affect user healthy.
For avoiding product to go mouldy, many producers all add some mould inhibitors before product export in water reducer.Because mould inhibitor price is higher, use cost is high, and has certain Use Limitation.Add the product of mould inhibitor still can produce and go mouldy after one to two month of use.User does not have effective treatment process after product goes mouldy, and all directly scraps and outwells, and causes waste and environment is produced to secondary pollution.
Summary of the invention
The object of the present invention is to provide a kind of hydrogen peroxide treatment process for the polycarboxylic acid series high efficiency water reducing agent that goes mouldy, easily go mouldy, waste the problem such as material and contaminate environment with what solve that prior art exists.
To achieve these goals, the invention provides a kind of hydrogen peroxide treatment process for the polycarboxylic acid series high efficiency water reducing agent that goes mouldy, it comprises the following steps: the polycarboxylic acid series high efficiency water reducing agent going mouldy is put into corrosion-resistant container; In described corrosion-resistant container, add hydrogen peroxide, and fully stir.
According to a kind of preferred implementation of aforesaid method, wherein, the concentration of described hydrogen peroxide is 27.5%, and adds 2 kilograms, hydrogen peroxide in the polycarboxylic acid series high efficiency water reducing agent going mouldy per ton.
According to a kind of preferred implementation of aforesaid method, wherein, the time of stirring is at least 30 minutes.
According to a kind of preferred implementation of aforesaid method, wherein, also comprise: the storage tank that the hydrogen peroxide of use 27.5% crosses to splendid attire the polycarboxylic acid series high efficiency water reducing agent going mouldy cleans, and avoids secondary pollution.
Test shows, after processing via the present invention, the polycarboxylic acid series high efficiency water reducing agent going mouldy can recover original performance, and color and existing product approach, peculiar smell removing.
Embodiment
Below in conjunction with embodiment, the present invention is described in further details.
For the polycarboxylic acid series high efficiency water reducing agent having gone mouldy, when application the present invention processes, should implement according to following steps:
First, the polycarboxylic acid series high efficiency water reducing agent going mouldy is put into corrosion-resistant container, the corrosion-resistant container that the materials such as such as glass reinforced plastic, PVC, PE are made.
Then, in corrosion-resistant container, add hydrogen peroxide, and fully stir.
Preferably, the concentration of hydrogen peroxide is 27.5%, and adds 2 kilograms, hydrogen peroxide in the polycarboxylic acid series high efficiency water reducing agent going mouldy per ton.Certainly, can also, according to the degree of going mouldy, select concentration and the quantity of hydrogen peroxide.
For the polycarboxylic acid series high efficiency water reducing agent that more thoroughly more energy-conservation processing is gone mouldy, in the time stirring water reducer and hydrogen peroxide, should enough fully stir, be no less than 30 minutes.
In addition, preferably use the storage tank that 27.5% hydrogen peroxide crosses to splendid attire the material that goes mouldy to clean, avoid producing secondary pollution to again depositing product in.
To sum up, utilize the present invention, the polycarboxylic acid series high efficiency water reducing agent having gone mouldy is effectively processed, simple to operate, can cut the waste and protection of the environment.Also can allow manufacturer need not add mould inhibitor, but at user terminal, the polycarboxylic acid series high efficiency water reducing agent after going mouldy be processed, reduce product cost.
As known by the technical knowledge, the present invention can realize by other the embodiment that does not depart from its spirit or essential feature.Therefore, above-mentioned disclosed embodiment, with regard to each side, all just illustrates, and is not only.Within the scope of the present invention all or be all included in the invention in the change being equal in scope of the present invention.
Claims (4)
1. for a hydrogen peroxide treatment process for the polycarboxylic acid series high efficiency water reducing agent that goes mouldy, it is characterized in that, comprise the following steps:
The polycarboxylic acid series high efficiency water reducing agent going mouldy is put into corrosion-resistant container;
In described corrosion-resistant container, add hydrogen peroxide, and fully stir.
2. method according to claim 1, is characterized in that, the concentration of described hydrogen peroxide is 27.5%, and adds 2 kilograms, hydrogen peroxide in the polycarboxylic acid series high efficiency water reducing agent going mouldy per ton.
