Abstract
The invention belongs to the technical field of inorganic salts, and especially relates to a method for preparing a sodium sulfate-hydrogen peroxide-sodium chloride adduct from solid waste mirabilite. The method concretely comprises the following steps: mixing mirabilite, hydrogen peroxide and sodium chloride, stirring and reacting above materials at room temperature for 30-60 min, carrying out reduced pressure suction filtration after the above reaction ends, and carrying out solid-liquid separation; and drying the obtained separated solid phase at 80-120 DEG C for 60-90 min in order to obtain the sodium sulfate-hydrogen peroxide-sodium chloride adduct.
Description
Technical field
The invention belongs to inorganic salts preparing technical field, particularly to one kind, sodium sulphate-peroxide is prepared using solid waste saltcake
The method changing hydrogen-sodium chloride adduct.
Background technology
Adduct sodium sulphate-hydrogen peroxide-sodium chloride is a kind of oxygen-containing washing assisant of neutral, nontoxic solid, is also one
Plant new oxygenation agent, disinfectant, bleaching assistant.Molecular formula is 4Na2SO4-2H2O2- NaCl, the mass fraction of hydrogen peroxide is
More than 9.2%, active o content is 4.6%.Due to 4Na2SO4-2H2O2The hydrogen peroxide that-NaCl generates after being dissolved in water occurs to divide
Solution, the elemental oxygen of releasing has bleaching, sterilization, decontamination and disinfective action, so having the property of hydrogen peroxide；It is dissolved in simultaneously
After water, pH value in aqueous is 6～8, close to neutral, frequently as detergent bleach auxiliary agent.
The production technology of traditional adduct sodium sulphate-hydrogen peroxide-sodium chloride mainly has following two：One kind is wet type
Preparation method, sodium sulphate, sodium chloride, stabilizer are dissolved in hydrogen peroxide, control the crystallization temperature worked as, are dried after separation to product
Product.Another is dry type preparation method, is stirred mediating by sodium sulphate, sodium chloride using mixer or kneader, uses simultaneously
Hydrogen peroxide sprays to mixture, prepared product.
Although adduct sodium sulphate-hydrogen peroxide-sodium chloride has plurality of advantages, when it is used as bleaching agent bleaching, deposit
In too fast, decomposition the phenomenon of decomposition rate, extra interpolation synergist or stabilizer is needed to slow down its decomposition rate；Should simultaneously
Product grains are tiny, and in production, dry, storage and transportation, crystal grain can be acted on due to crystal, be bonded to each other, go out
The phenomenon of existing product caking.
Saltcake, NaSO4·10H2O content >=85%, monoclinic system, generally in pelletized form, block, soluble in water, there is moisture absorption
Property.Chemical fibre factory or embrane method are removed chlor-alkali plant of nitre etc. and are had a common difficulty it is simply that the accessory substance saltcake producing does not have at present
There is market, remaining beneficial composition is all abandoned as waste, become new solid waste, in a large amount of saltcake accumulations and transportation very
Easily cause the problems such as soil and underground water pollution.The saltcake of particularly some by-products contains the Hubeiwans such as cellulose, therefore
How to reduce the environmental pollution that saltcake solid waste is brought, turn waste into wealth, increase operation rate, make the product of higher value, become
For people's concern.
Content of the invention
The technical problem to be solved is：There is particle size distribution in adduct sodium sulphate-hydrogen peroxide-sodium chloride
, when being used simultaneously as bleaching assistant bleaching, there is too fast, decomposition the phenomenon of decomposition rate, need volume in the shortcomings of differ from, easily lump
Outer interpolation synergist or stabilizer slow down its decomposition rate, cause the increase of cost.
The present invention replaces traditional sodium sulphate as the raw material of reaction using the solid waste saltcake doped with impurity, prepared by two-step method
Adduct sodium sulphate-hydrogen peroxide-sodium chloride, when being used as bleaching assistant with the adduct product that this raw material is prepared, bleaching is steady
Qualitative decomposition that is higher, effectively inhibiting adduct product, improves bleaching utilization rate；This Granularity Distribution is equal simultaneously
Even, autonomous resistive connection block effect is good, solves that current saltcake solid waste environmental pollution is serious, the low problem of resource utilization, very simultaneously
The good cost reducing raw material in traditional preparation method.
In order to achieve the above object, the present invention adopts the following technical scheme that：
(1) sodium sulphate, hydrogen peroxide, sodium chloride three's mol ratio 1.2～2.5 are pressed：2.1～3.5：0.8～1.6, by awns
Nitre, hydrogen peroxide and sodium chloride mixing, stirring reaction 30～60min under the conditions of room temperature (25 DEG C), react the suction filtration that reduces pressure after terminating,
Carry out separation of solid and liquid,
Wherein, the married operation of saltcake, hydrogen peroxide and sodium chloride is, saltcake and sodium chloride are added to aquae hydrogenii dioxidi
In solution,
Wherein, saltcake composition calculates according to percetage by weight, needs to be controlled to：Cellulose sulfonate 2%～5%, crystallite
Cellulose 2%～3%, trithiocarbonic acid sodium 1%～2%, niter cake 0.5%～1%, sulphur 0.5%～1%, zinc sulfate
1%～2%, balance of NaSO4·10H2O,
In the presence of cellulose sulfonate, microcrystalline cellulose, zinc sulfate are with above-mentioned content, can at utmost improve sodium sulphate-
The mobility of hydrogen peroxide-sodium chloride adduct, strengthens its anti-caking performance, main reason is that cellulose sulfonate contains ester
Base, this group has hydrophobicity, and the polysaccharide polymer structure of cellulose sulfonate and microcrystalline cellulose can be adsorbed in adduction simultaneously
Thing surface forms hydrophobic layer, hinders the exchange of adduct and moisture in air, can effectively prevent adduct from luming；Except this with
Outward, the synergy between each composition and adduct, effectively inhibits the too fast decomposition of adduct, slows down it to being bleached
The radical response of thing, improves its effective, lasting utilization rate,
If trithiocarbonic acid sodium content be higher than 2%, generate hydrate because it is highly soluble in water, can affect sodium sulphate-
The anti-caking performance of hydrogen peroxide-sodium chloride adduct, simultaneously niter cake there is hygroscopicity, content also must control 1%
Within,
Wherein, the Solute mass fraction of aqueous hydrogen peroxide solution is 30%, purity >=99.7% of NaCl in sodium chloride；
(2) solid phase after separating step (1) dries 60～90min at 80～120 DEG C, obtains sodium sulphate-peroxidating
Hydrogen-sodium chloride adduct product.
Present invention also offers a kind of adduct sodium sulphate-hydrogen peroxide-sodium chloride that obtains of above-mentioned preparation method should
With, will adduct sodium sulphate-hydrogen peroxide-sodium chloride as bleaching agent.
The present invention compared with prior art has following advantages and effect：
(1) present invention provides a kind of solid waste saltcake to be used as adduct sodium sulphate-hydrogen peroxide-sodium chloride raw materials for production, system
, as resolution ratio ＜ during bleaching assistant 85%, effective rate of utilization is high, stability is preferable, through the pure cotton fabric after bleaching for the finished product becoming
Brightness gain >=50%, 35 ° of static angle ＜ in resistive connection test simultaneously, preferably, autonomous anti-caking performance is excellent for product mobility
Different.
(2) saltcake is replaced traditional anhydrous sodium sulfate to be applied to prepare product by the present invention, and saltcake gives up for common industrial
Gurry, so turns waste into wealth it is achieved that the recycling of mirabilite resource.
(3) present invention makes full use of the particularity of raw material feature and process, significantly reduces production cost, is suitable for
Use in heavy industrialization.
