Abstract
A kind of preparation that is used for whitening sodium sulfate belongs to the vitriol production technical field.It is that application is that host, phenolic ether and alcohol ether nonionogenic tenside are that synergistic agent, alcohols and deionized water are the treatment compositions that brightens of solvent with the white dyes.The weight percent of each component is:
White dyes 1---5%
Alcohol ether surface active agent 2---5%
Phenolic ether surfactant active 8---15%
Alcohols 1---5%
Deionized water 70---88%
With this preparation sodium sulfate is handled, made its whiteness value improve 5 degree relatively.
Description
The present invention is a kind of preparation that the sodium sulfate product brightens that is used for, and belongs to the vitriol production technical field.Sodium sulfate is a kind of vitriol, and commercial sulphuric acid sodium has anhydrous sodium sulphate and contains the sodium sulfate of ten crystal water, is one of important chemical material, and it also is one of main auxiliary agent of washing composition.The production method of sodium sulfate is a lot, present industrial sulphuric acid sodium mostly is natural producing greatly and processes from strand, but the sodium sulfate product that utilizes prior art to produce, its whiteness value is at the 80-85 degree, have the not high shortcoming of whiteness value, the sodium sulfate product of preparation ultrahigh brightness has become a difficult problem.
The objective of the invention is composite a kind of preparation that the sodium sulfate product brightens that is used for, said preparation is handled sodium sulfate, make it have higher whiteness.
The present invention is achieved in that with the white dyes to be host, be that synergistic agent, alcohols and deionized water are solvent with alcohol ether and phenolic ether nonionic surface active agent, the weight percent of each component is:
White dyes 1-5%
Alcohol ether surface active agent 2-5%
Phenolic ether surfactant active 3-15%
Alcohols 1-5%
Deionized water 70-88%
According to aforementioned proportion, in 60 ℃ deionized water, add white dyes earlier, under agitation condition, add phenolic ether surfactant active more successively, the alcohol ether surface active agent adds alcohols at last, continues to stir, each component up to above-mentioned adding is dissolved fully, form the uniform Lightening compositions preparation of concentration, then said preparation directly sprayed cloth on the sodium sulfate powder surface, the consumption of said preparation be by weight percentage spray the 2-3% that cloth brightens the sodium sulfate of processing.
The present invention is easy and simple to handle, and cost is low, can make the whiteness value of sodium sulfate improve 5 degree relatively, and have higher brightness and better gorgeous degree.
It is to be a kind of fluorescence dye or white dyestuff according to white dyes that the present invention makes the principle of whitening sodium sulfate, white dyes is except the light that can absorb visible spectrum, also absorb a part of sightless ultraviolet ray, the latter with the long visible rays of wavelength, mainly is that blue light and purple light are reflected out again.Therefore the sodium sulfate of being handled by white dyes will send the visible rays that partially absorbs the more volume of coming than it from the spectrographic visible light, and because the reflected light that increases has blue light and purple light, they just can offset the yellow of sodium sulfate itself, and become pure white color.Alcohol ether and phenolic ether nonionogenic tenside because contain hydroxyl (OH) and phenyl (
) two auxochrome groups, these auxochrome groups are to blue light and purple light synergy, and their adding is fine to the enhancement effect of white dyes, and is very strong to the outward appearance whitening effect of sodium sulfate.
Embodiment:
Choosing the two triazine type white dyess of diaminostilbene disulfonic acid is white dyes, and its structure is as follows:
Nonyl pheno
(10)Ether is phenolic ether surfactant active, and its molecular formula is
As follows.
Aliphatic alcohol polyethenoxy
(9)Ether is pure ether surface active agent, and its molecular formula is R(OCH
2CH
2)
9OH, R=C
12H
25-C
18H
37,
As follows.
Alcohols is an ethanol, and its molecular formula is CH
3CH
2OH,
As follows.
Be by weight percentage:
The two triazine type white dyess 2% of diaminostilbene disulfonic acid
Nonyl pheno
(10)Ether 10%
Aliphatic alcohol polyethenoxy
(9)Ether 5%
Ethanol 3%
Deionized water 80%
Ratio, in 60 ℃ the container of deionized water is housed, add the two triazine type white dyess of diaminostilbene disulfonic acid earlier, under agitation condition, add Nonyl pheno more successively
(10)Ether, aliphatic alcohol polyethenoxy
(9)Ether adds ethanol at last, continues to stir, and dissolves fully up to the above-mentioned component that respectively adds, and forms the composite preparation that concentration brightens uniformly.Get above-mentioned preparation 30 grams, directly spray cloth equably with the nozzle of general spraying plant and restrain on the sodium sulfate powder surfaces 1000.The situation that whiteness value after the sodium sulfate of having enumerated different whiteness values in the subordinate list is handled with above-mentioned preparation and method increases.
