Abstract
The invention discloses a special dust-depressor for metal mineral powder and ores. The dust-depressor is prepared from magnesium chloride, calcium chloride, sodium sulfate, sodium carboxymethylcellulose, attapulgite, alkyl polyglucoside, water-soluble imidazoline corrosion inhibitor, chitosan and mineral oil. The special dust-depressor has good hygroscopic water retention, good film-forming property and coagulation performance and good stability, corrosion resistance and anti-frost property; above all, the special dust-depressor does not react with metal, is non-poisonous and odorless and has high application value.
Description
Technical field
The present invention relates to dust-inhibitor, relate in particular to the dust-inhibitor of a kind of metal mining powder and metallic ore special use.
Background technology
Coal, mineral bulk cargo generally all adopt open-top car transportation in transportation by railroad, in transportation due to roadbed, what track switch and rail facility caused jolts, add a variety of causes such as wind effect and make the powder on coal in vehicle, the mineral bulk cargo surface ground of being scattered, not only caused loss and polluted, coal ash or mineral powder are trickled down on equipment, electric appliance circuits also can bring serious security incident and hidden danger to transportation by railroad.So the improvement of airborne dust is very urgent and necessary.
Existing solution has: physics dust suppression method and chemical dust suppression method.Physics dust suppression method has machinery to add a cover method, tarpaulin covering method, and watering etc., these methods all can not effectively be dealt with problems, and the corrosion of tarpaulin also can form secondary pollution.Chemistry dust suppression method is that dust-inhibitor is sprayed onto to coal, mineral surface by the mode spraying, and forms effective protective layer and reaches the object that suppresses dust.Conventionally dust-inhibitor has at least one in film forming, wetting and three kinds of performances of coalescence.The report of at present relevant coal dust depressor is more, but also there is no metal mining powder, the special-purpose dust-inhibitor of ore.Because metal mining powder, ore are different from carbon dust performance, the dust-inhibitor that therefore existing coal is used can not be applied to metal mining powder conventionally, ore is used.
Summary of the invention
The object of the invention is to develop a kind of metal mining powder, the special-purpose dust-inhibitor of ore, this dust-inhibitor does not react with metal, nontoxic, tasteless.
Technical scheme of the present invention is: a kind of metal mining powder, the special-purpose dust-inhibitor of ore, it is characterized in that, by the component of following weight parts, formed: magnesium chloride 4-6, calcium chloride 8-12, Xylo-Mucine 0.8-1.2, attapulgite 4-6, sodium sulfate 0.8-1.2, APG (APG) 1.5-2.5, water-soluble imidazoline inhibiter 0.2-0.5, chitosan 0.3-0.6, mineral oil (technical grade) 0.8-1.2, water 100-150.
Optimum ratio is: magnesium chloride 5, calcium chloride 10, Xylo-Mucine 1, attapulgite 5, sodium sulfate 1, APG (APG) 2, water-soluble imidazoline inhibiter 0.3, chitosan 0.5, mineral oil (technical grade) 1, water 120.
Preparation method: above-mentioned raw materials is added to the water, adopts common whipping device to mix.
Using method: according to Dust Capacity size, above-mentioned dust-inhibitor dilution 20-100 is doubly sprayed to the exploitation place of the transport train of metal mining powder, metallic ore or metal mining powder, metallic ore, concrete spray method is with existing coal inhibitor.
The effect of each component is as follows:
Calcium chloride and magnesium chloride have certain moisture-absorption water-retention, and have good anti-evaporating, are conducive to keep the water content of dust-inhibitor, and have certain frost resistance.
Xylo-Mucine: anionic ether of cellulose is white or oyster white fibrous powder or particle, odorless, tasteless almost, tool water absorbability.Be easy to be dispersed in water into transparent colloidal solution, insoluble in the organic solvents such as ethanol.There is the effects such as bonding, thickening, enhancing, emulsification, water conservation, suspension.
Sodium sulfate: there is certain moisture-absorption water-retention, and can further strengthen the performance of Xylo-Mucine.
Attapulgite: be a kind of have chain laminate structure containing Shuifu County's magnesium silicate clay mineral.Thickening property is good, and suspension is good, and absorption property is good, insulation, and unreactiveness, pollution-free, suppress microorganism growth, absorb poisonous volatile component, environmental protection.
APG APG: the composition being formed by alkyl list glucoside, alkyl maltoside etc., APG of the present invention is preferably APG-0814(alkyl carbon number 8-14) or APG-1214(alkyl carbon number 12-14), APG is dewatered with alcoholic extract hydroxyl group by sugared hemiacetal hydroxyl and the compound that generates under an acidic catalyst effect, it is different from traditional emulsifying agent, it derives from natural raw material, do not contain oxyethane or other chemical solvents, and being easy to biological degradation and can not causing the pollution to environment, is that a new generation is gentle, green, environment-friendly type tensio-active agent.From molecular structure, APG belongs to nonionogenic tenside, but has the advantage of nonionic and anion surfactant concurrently: surface tension is low; Latherability is strong, and foam is fine and smooth, abundant, stable; Wettability is good; Compatibility is splendid, has good syneryistic effect with other tensio-active agents, without cloud point, soluble in water, is easy to dilution, and gel-free phenomenon is easy to use; Anti-oxidant, resistance to hard water, dispersion of calcium soap is strong; Green, nontoxic, non-stimulated, biological degradation is thorough rapidly; There is stronger broad spectrum antibiotic activity.There is easy degraded, do not pollute the features such as farm crop and soil, good hygroscopicity.
Water-soluble imidazoline inhibiter: be after naphthenic acid reacts with organic polyamine, water-soluble, the oil-soluble inhibitor that through modification, form.Under middle hot conditions, to HCl-H
2s-H
2the corrosion of O system has good restraining effect.
Chitosan: be that the chitin (chitin) extensively being existed by nature obtains through deacetylation, there is good film forming properties.
Mineral oil (white oil): molecular weight is conventionally all within 250-450 scope.There is good oxidation stability, chemical stability, light stability, colourless, tasteless, do not corrode fiber textile.There is good moisturizing, emulsification and film forming properties.
Effect of the present invention is: the present invention is with magnesium chloride, calcium chloride, sodium sulfate, Xylo-Mucine, attapulgite, APG, water-soluble imidazoline class inhibiter, chitosan and mineral oil prescription, there is fabulous moisture-absorption water-retention, good film-forming properties and coalescence performance, and stability, anticorrosive and good frost resistance, the more important thing is not and metal reaction, nonpoisonous and tasteless, there is good using value.
