Description
Technical field:
The present invention relates to a kind of dust-inhibitor that is mainly used in the road surface dust Control, can be used for the dust Control on road surface, mine, production site and urban road square etc.
Background technology:
At present, common both at home and abroad dust suppression technological method is except that watering dust suppression (containing watering, spraying, the ultrasonic static water that involves), and it is several to spray wetting agent, solid/liquid moisture adsorbent, dust adhering agent, high power water-absorbing resin and compound dust-inhibitor in addition.In, state such as U.S., day, moral, Russia, Australia all carried out the research to dust-inhibitor.In recent years, along with the development of polymer fine chemical technology, aspect super strength water absorbent, make progress.But it is high or have drawbacks such as toxicological characteristics, corrodibility, difficult degradation and secondary pollution to go back ubiquity function singleness or price.Though have stronger agglutinating value(of coal) as the dust-inhibitor of making base-material with crude oil, pitch and residual oil etc., can not moisture-absorption water-retention, the variation of temperature that can not conform, and have toxicity, bio-refractory; With CaCl
2, MgCl
2Though add tensio-active agent such as lipid acid, sodium laurylsulfonate etc. and make wetting agent and adopt dust-inhibitors such as super strength water absorbent such as sodium polyacrylate to have stronger water-absorbent in halogenide and ammonium sulfate, sodium bicarbonate etc. inorganic salt, but agglutinating value(of coal) is poor, and has problems such as toxicity, corrodibility, volatility and bio-refractory.
Summary of the invention:
In order to overcome existing dust-inhibitor function singleness, cost performance is low, or has secondary pollution environmental problems such as toxicity, corrodibility, bio-refractory, the invention provides a kind of dust-inhibitor prescription, this dust-inhibitor not only has dust suppression over-all propertieies such as the coalescence of cohering, moisture absorption and water conservation, and can suitably improve the water and soil environment, the fixed road surface of safeguarding, strengthen the anti-spreading performance on road surface, prevent the soil erosion on soil property road surface and damage cost performance height, nontoxic nothing corrosion, easy biochemical degradation, non-secondary pollution; Preparation and spray processing are simple.
The technical solution adopted in the present invention is: this dust-inhibitor is formed by cohering coalescence, moisture absorption and three major portions of full water.One is the coalescence factor.This factor can become tiny dust granules coalescence bigger particle and have good consolidation strength, thereby, reduce the rate of kicking up of dust and the anti-spreading of ground (soil property or cementaceous), reduce reentrainment of dust.Its two, be the moisture absorption factor.This factor has stronger water absorbability, can absorb airborne moisture content, keeps the moistening of dust suppression road surface, thereby the substance of increase dust granules reduces airborne dust.Particularly when night temperature reduce, the moisture content that the is evaporated face of land of coming in the daytime, the road surface is under the effect of moisture absorption factor hydrophilic group, fully moisture absorption makes the moisture content of evaporation obtain in time replenishing, thereby strengthens the ageing of dust suppression.Its three, be the water conservation factor.The effect of this factor is to form one deck molecular film on the dust granules surface that is surrounded by water, and to reduce the velocity of evaporation of moisture content, the moisture content that reduces ground dust suppression layer runs off.The solution of its configuration has the over-all properties of cohering coalescence, moisture absorption and water conservation, can reduce the surface tension of water.
The coalescence factor is carboxymethyl starch (Carboxyl Methyl Starch is called for short CMS) in the dust-inhibitor, it is a kind of white powder, stirring in natural water at normal temperatures is solubilized, immersion process will help shortening the required churning time of dissolving, in dust-inhibitor, this components contents is 0.1-3.0%.The moisture absorption factor is water glass (Sodium Silicate) crystal, white, and soluble in water, this components contents is 0.01-2.50% in dust-inhibitor.The water conservation factor is glycerol (Glycerine also claims glycerine), is colourless liquid, and its content is 0.01-2.00%.
Be that the present invention is made up of carboxymethyl starch, water glass and glycerol, its proportioning is respectively 0.1-3.00%, 0.01-2.50% and 0.01-2.00%, and surplus is supplied by water.Before enforcement, dust-inhibitor is three kinds of independently components; When preparing dust-inhibitor during enforcement,, be prepared into the solution of above proportioning with water as solvent.Promptly calculate the weight of three components, again the water yield is filled up to 100%, three components are soaked the back or directly stir in water and make it fully that dissolving gets final product by total solution weight and proportioning.
The performance index of preparation back dust-inhibitor are: (1) pH value: 〉=6.5; (2) viscosity: 〉=300mpas; (3) high temperature resistant: 〉=45 ℃; (4) improve saturated water absorption: the saturated water absorption 20% that improves roof and floor soil and dust; (5) reduce rate of permeation: dust infiltration rate average out to 2.81 mm/min under field conditions (factors) are 0.05 mm/min under dust-inhibitor, have improved the surface adsorption effect of dust, and the moisture-absorption water-retention time is long; The anti-evaporating time under (6) 45 ℃ of constant high temperatures: 65 hours (till water content 4%), vaporator rate is 4.8 Grams Per Hours, unit surface vaporator rate 0.678 gram per centimeter
2(7) improve anti-abrasive property: adopt the XMQ-240X90 conical bell mill, rotating speed 96RPM, milling time 30 seconds, (percentage composition of D＜0.08mm) is 6.43% to be lower than 200 orders; (8) fine dusts is had strong cohesive action, fixed road surface, the flushing that the shale road surface is caused that can prevent to sprinkle water destroys; (9) surface tension reduces, basically eliminate the reentrainment of dust when spraying.
Each component of dust-inhibitor can independently store by component before enforcement, also can be prepared into solution by proportioning and store.
Can replace water glass with bibulous weak acid strong alkali salt.Described bibulous weak acid strong alkali salt is meant yellow soda ash, sodium bicarbonate, salt of wormwood.
Present embodiment adopts the spray liquid mode to use, and except that increasing dust-inhibitor preparation facility and process for preparation, its use is suitable with watering dust prevention.
The invention has the beneficial effects as follows, with the effective combination of coalescence, moisture absorption and water conservation, the dust suppression time is long, the cost performance height, technical matters and simple to operate, the without any side effects and corrosive nature of independent component and solution thereof, dust suppression action period later can be at the very fast biochemical degradation of nature, do not have any secondary pollution, and can suitably improve the water and soil environment.This dust-inhibitor also can be used for urban road, square except that the inhibition that is used for the thick big dust of mine road, building field, and the inhibition of dust such as station terminal is limited by hardly in the place, and is with a wide range of applications.This invention is carried out industrial application in the soil property place of middle aluminium Guangxi branch office mine transportation highway and the thick big dust of ore drawing platform, and application shows, sprays once (0.2-1.0L/M
2) after, dust suppression working lipe is more than 5 days, Air quality all reaches secondary or grade III Standard, and significantly reduce the human and material resources and the financial resources consumption of sprinkling, reduce the unit cost (0.77 yuan/ton) of ore, year saving water resources 11 ten thousand steres are obtained tangible economic benefit.This technology in January, 2003 by evaluation at the provincial and ministerial level.
