Abstract
The invention belongs to ion exchange resin regeneration research field, more particularly to a kind of high-effect soft water salt and preparation method thereof.Abrading-ball and sodium chloride are added in ball grinder first, add abundant ball milling after Synergistic additives, coagulator and binder, obtains powder salt；Prepared powder salt is poured into comminutor again, and sprays into distilled water, spherical granules are obtained after granulation and dries, i.e., high-effect soft water salt particle.Soft water salt particle hardness is strong, is not easy to put up a bridge, at sticking together, and reduces the dissolving loss of salt, prevents the water softening device fouling caused by hard object, booty and sediment, extend the service life of equipment；And the raising of water-softening power can extend resin life.
Description
Technical field
The invention belongs to ion exchange resin regeneration research field, more particularly to a kind of high-effect soft water salt and its preparation side
Method.
Background technology
As the improvement of people's living standards, the requirement to domestic water is higher and higher, occur in the market various
Water softening device meet the needs of people.In water softening device for water process method it is main, it is most advanced and it is optimum be ion
Switching technology.After pending raw water is by resin, the objectionable impurities ion (predominantly calcium Ca, magnesium Mg ions) in water can be inhaled
It invests in resin, reaches purpose of purifying the water quality.With the increase of water process amount, the foreign ion of absorption is more and more, resin
Adsorption capacity can continuously decrease, form a kind of failure state, and want Scavenger resin adsorb foreign ion, it is necessary to sodium from
Son cements out the foreign ion of resin adsorption by ion-exchange method, to restore the adsorption energy of ion exchange resin
Power, this process are also ion exchange resin regeneration.
Soft water salt is a kind of product salt that can efficiently go hardness (calcium and magnesium ion and some other scale impurity) in water removal,
Regeneration reducing resin keeps water quality cleaner, limpid, long-term to keep that feedwater piping is unobstructed, Non-scale, without any residual after use
Object is higher than any regenerative agent under comparable conditions without any smell, and the water softening device for being suitable for various models uses.
But during soft water salt is soaked in salt box, phenomena such as being easy to happen loose disintegration, blocks salt box water outlet, shadow
Regeneration of ion-exchange resin process is rung, the normal operation of water softening device is directly affected, water softening device can be caused to damage when more serious,
Unnecessary loss is brought, while salt waste is larger.Therefore, soft water carbonate hardness is improved, reduces rate of dissolution, accelerate removal gold
Belong to the inexorable trend that the technical improvement methods such as ion velocity become the development of soft water salt.
Invention content
Technical problem solved by the invention is：During soft water salt is soaked in salt box, it is easy to happen loose disintegration
Phenomena such as.In order to solve the above technical problems, the technical solution adopted by the present invention is：
A kind of high-effect soft water salt is provided, component includes sodium chloride, Synergistic additives, coagulator and binder.
The present invention also provides a kind of preparation methods of above-mentioned high-effect soft water salt, specially：
(1) abrading-ball and sodium chloride are added in ball grinder, are added after Synergistic additives, coagulator and binder fully
Ball milling obtains powder salt,
Wherein, the mass ratio of abrading-ball and sodium chloride is 1：1~4：1,
Mass ratio between Synergistic additives, coagulator, binder is 1：3：2~1：6：5,
Ball-milling Time is 1~2h, the powder salt grain size obtained after ball milling at 200 μm hereinafter,
Wherein, coagulator is the mixed of one or more of EDETATE DISODIUM, distannous citrate, curdlan
Object is closed,
Coagulator is used to stablize the internal structure of chlorination sodium molecule, reduces its mobility, makes powder salt stable structure, be added to
Ball intensity,
Binder be carragheen, food-grade starches binder, gelatin, one or both of food grade silicone binder with
On mixture,
To make powder salt, preferably tight bond, enhancing powder salt adhesion strength keep it more preferable to binder in granulation process
Ground caking balling-up,
Synergistic additives are metal-organic complex or organic and inorganic polymer, specially bodied ferric sulfate, polyaluminium
The mixture of one or more of aluminium, chitosan, sodium humate；
(2) powder salt prepared in a part of step (1) is poured into the comminutor under working condition, then sprays into a part
Distilled water repeats the operation 2~5 times until all powder salts are introduced into comminutor, obtains spherical granules and dry, obtain efficiently
Energy soft water salt particle,
Wherein, comminutor is granulating disc, and rotating speed is the uniform rotation of 20~50Hz,
The distillation water inventory of penetrating is 3%~10% with the mass ratio of powder salt totality,
The grain size of the obtained spherical granules of control is 2~3cm,
Drying temperature is 80 DEG C.
The beneficial effects of the present invention are：The present invention in sodium chloride by being added Synergistic additives, coagulator, bonding
Agent makes grain size reach 200 μm hereinafter, being granulated using granulating disc, the spherical granules of gained through ball mill ball milling
The purity of salt is up to 99.5% in soft water salt, and particle diameter distribution is uniform, surface is smooth, anatomic shape is consistent, hardness is strong, does not take
Bridge, not at sticking together, reduce salt dissolving loss, prevent the water softening device fouling caused by hard object, booty and sediment, extension to set
Standby service life；
Soft water quality is good, can accelerate the rate for removing metal ion, and the ability for removing metal ion is far above general soft water
Salt double can remove the impurity in water removal, and also more common soft water salt is higher by about 2 times to water-softening power, can extend resin life, improves
Soft water quality and efficiency.
