Abstract
Slow-soluble salt and a preparation method are characterized in that the soluble salt comprises sodium chloride powder salt and calcium oxide. The calcium oxide occupies 0.1% to 5% of sodium chloride by weight. The preparation method includes first evenly mixing the powder salt and the calcium oxide, conducting compression molding on the mixed materials and finally naturally placing the molded body for one week to obtain an end product. The slow-soluble salt and the product have the advantages of 1 being capable of achieving slow solubility, enabling solution speed of salt in water to be greatly reduced and being capable of completely controlling solution speed of the salt in water according to different prescriptions; 2 being capable of utilizing salt powder dust for production to achieve waste utilization, save resources and purify environment; 3 being suitable for requirements of other industries except for meeting requirements for industrial production, for example, adding various nutrition constituents to manufacture licking blocks required by animal husbandry cultivation; and 4 being simple in process, suitable for use, low in product manufacture cost and suitable for large area popularization.
Description
Technical field
The present invention relates to Industrial Salt field, specifically a kind of slow dissolved salt and preparation method thereof.
Background technology
Salt is had many uses industrial, is one of the most basic raw material of chemical industry, is described as " mother of chemical industry ".Industrial salt major part is for the production of soda ash, caustic soda, chlorine, hydrochloric acid, sodium Metal 99.5 etc.In colored metallurgical industrial for copper metallurgy (chlorinating roasting), electrolytic metal magnesium.The new purposes of making catalyzer with salt is that salt combines with tapping a new source of energy.In these industrial production, they all have very high requirement to the concentration of salt, and in use the concentration of salt is constantly changing, in order to keep, salt concn is unlikely to be varied widely, and needs constantly in solution, to add salt block, so just need to waste a large amount of manpowers, require great effort time-consuming.Moreover industrial salt more than 20% stems from well mine salt, well mine salt is compared with sea salt, exists thin brilliant morely, dissolves too soon, and during especially for connection alkali industry, in production, meeting affect grain size number, easily stops up handling equipment.
Therefore, the dissolution rate too fast problem of these industries salt in the urgent need to address in solution, to reach the object of controlling concentration of salt solution.
summary of the invention:
Object of the present invention is exactly for the problem of above-mentioned prior art and a kind of slow dissolved salt of special development and preparation method thereof.
The object of the invention is to realize by the following technical solutions:
Slow dissolved salt of the present invention comprises that sodium-chlor powder salt and calcium oxide form.The weight ratio that described calcium oxide accounts for sodium-chlor is 0.1%-5%.Be preferably 1%-4%.
The making method of slow dissolved salt of the present invention comprises the following steps: according to ratio of components, weigh powder salt, calcium oxide, powder salt and calcium oxide are mixed, then by the material compression moulding mixing, finally by naturally placing in the base substrate air of forming after one week, be finished product.
Described compression moulding is by pressing machine or Special forming machine compression moulding.
The present invention has following effect:
1) can reach slow molten, the dissolution rate of salt in water reduced greatly, according to different formulas, can control the dissolution rate of salt in water completely.Be less than sea salt with sea salt its dissolution rate of more onesize particle of putting together.
2) can utilize salt dust to produce, reach utilization of waste material, economize on resources, environment purification.
3) except meeting industrial needs, be also applicable to the needs of other industry, for example livestock industry licks with licking the needs that salt is produced.
4) technique is simply applicable, and this cost of goods manifactured is lower, suits large area to popularize.
Embodiment
Following examples of the present invention are further described:
Embodiment 1:
Accurately weigh sodium-chlor powder salt 100 weight parts, calcium oxide 0.5 weight part, pours mixer into and mixes.The material mixing is placed on to compression moulding on forming machine, and typed pressure is 50MPa, by the good idiosome seasoning of compression moulding one week, packs and is finished product.After tested, the more complete 1cm of crystallization
3sea salt within 10 minutes, dissolved, and the powder salt of same volume is dissolved for 2 minutes, the slow dissolved salt dissolution time of same volume is greater than 20 minutes.
Embodiment 2:
Accurately weigh sodium-chlor powder salt 100 weight parts, calcium oxide 3 weight parts, mix the two with mixer.Other processes are with embodiment 1.
Core of the present invention is calcium oxide, after adding sodium-chlor compression moulding, in air, absorb airborne moisture and carbonic acid gas and generated calcium carbonate, calcium carbonate has become framework material, sodium-chlor after extrusion forming has been had support and under can not piling fast when water-soluble (one puts into water loses original shape), utilize the skeleton gap that calcium carbonate forms to dissolve, reached slow molten object.
Claims (2)
1. a manufacture method for slow dissolved salt, is characterized in that: this slow dissolved salt is comprised of sodium-chlor powder salt and calcium oxide, and the weight ratio that calcium oxide accounts for sodium-chlor powder salt is 0.1%-5%, concrete manufacturing step is as follows: first sodium-chlor powder salt and calcium oxide are mixed, then the material mixing is placed on to compression moulding on the forming machine that pressure is 50MPa, finally the good base substrate of compression moulding is placed 1 week in air and obtained slow dissolved salt finished product, can make the calcium oxide in slow dissolved salt in air, absorb airborne moisture and carbonic acid gas generation calcium carbonate, calcium carbonate has become framework material, sodium-chlor powder salt after extrusion forming has been had support and under can not piling fast when water-soluble, utilize the skeleton gap that calcium carbonate forms to dissolve, to reach slow molten object.
2. the manufacture method of slow dissolved salt as claimed in claim 1, is characterized in that: the weight ratio that calcium oxide accounts for sodium-chlor powder salt is 1%-4%.
