Abstract
The present invention relates to method of preventing powdered material from flying to the air and antidusting agent. The method includes preparing colloidal antidusting agent in very low concentration with starch, water and additive; and spraying the antidusting agent to the surface of piled matter to form one solid shell after drying to avoid flying to the air effectively. The antidusting agent is produced at normal temperature and has simple harmless material, simple production process and simple usage. The present invention may be used widely in building site, refuse landfill, etc to protect environment effectively.
Description
Technical field
The present invention relates to a kind of method and dust-proofing agent of preventing powdery stores airborne dust that uses in places such as construction site, refuse landfills.
Background technology
In order to protect environment, reduce airborne sand and dust content, government has put into effect various rules and regulations, requires powdery stores places such as construction site, refuse landfill must take various dust preventions, and the existing current practice is to adopt woven cloth to cover.Yet the operation that covers stores with woven cloth comparatively bothers, the higher construction cost that increased of the cost of woven cloth not only, and need take a large amount of manpowers and man-hour.In addition, woven cloth is very easily damaged under big wind action, needs constantly to change, and this has further increased construction cost, and the damaged untimely replacing in position also can cause environmental pollution.
Summary of the invention
At the problems referred to above, the object of the present invention is to provide a kind of cost low, easy to operate, dustproof obvious results prevents the method and the dust-proofing agent of powdery stores airborne dust.
For achieving the above object, the present invention takes following technical scheme: a kind of method that prevents powdery stores airborne dust, it is starch to be added entry and additive is made the very low colloid dust-proofing agent of concentration, described dust-proofing agent packed into have in the container of nozzle, be sprayed at the stores surface, make the stores surface after doing admittedly form one deck solid shell.
A kind of dust-proofing agent that prevents powdery stores airborne dust, it is characterized in that it adopts following method to make: the water that adds weight and be 7～9 times of starch in common starch stirs and becomes water-starch solution, the oxygenant that adds weight and be starch 3～6% in described solution stirs, the paste agent that adds weight in the solution after oxidation and be starch 10～12% stirs, and the linking agent that adds weight in the solution after described gelatinization and be starch 0.2%～0.6% stirs.
Another kind prevents the dust-proofing agent of powdery stores airborne dust, it is characterized in that it adopts following method to make: in the modified starch of pre-gelatinization, the water that adds weight and be 7～9 times of described modified starches stirs and forms water-starch solution, add the linking agent of described modified starch weight 0.2%～0.6% in solution, stirring gets final product.
Described oxygenant can be that concentration is that 27% hydrogen peroxide or content are 1% potassium permanganate.
Described paste agent can be that concentration is 30% sodium hydroxide solution.
Described linking agent can be a borax.
The present invention is owing to adopt above technical scheme, it has the following advantages: 1, the inventive method is base-material with starch, add additive, make it form the not stratified colloid that is very thin pasty state after mixed solution, therefore can put into container with nozzle, be sprayed on the powdery stores, make stores surface shape one deck solid shell, thereby can stop the stores airborne dust.2, the inventive method compared with prior art, execute-in-place is simple, and is dustproof reliable for effect, cost is cheap especially, owing to do not contain any hazardous and noxious substances in the raw material of the present invention, can not produce any detrimentally affect simultaneously, have boundless promotion prospect environment and soil.3, the production process of dust-proofing agent of the present invention can be finished at normal temperatures, no special requirement, and material requested is simple and easy to, and particularly starch is made the modified starch of pre-gelatinization, makes operation simpler, convenient transportation.The present invention goes for the place of powdery storess such as various construction sites, refuse landfill.
Embodiment
The inventive method is starch to be added entry and additive makes it become the very low colloid of a kind of concentration, the colloid that obtains packed into have in the container of nozzle, be sprayed at the stores surface, make the stores surface of doing after solid form one deck solid shell, and then realize stoping the stores in the shell to be swept the purpose of airborne dust to the environment by wind.
Dust-proofing agent of the present invention can adopt following method to make: at normal temperatures, the water that in common starch, adds 7～9 times of weight, stir and form water-starch solution, the oxygenant that adds weight and be starch 3～6% in solution stirred 20～30 minutes, the paste agent that adds weight in the solution after oxidation and be starch 10～12% stirred 30～40 minutes, and the linking agent that adds weight in the solution after gelatinization and be starch 0.2%～0.6% stirs.
Among the above-mentioned dust-proofing agent embodiment, oxygenant can be that content is 27% hydrogen peroxide, also can be that content is 1% solid potassium permanganate, and perhaps other has the oxygenant of identical effect.It is 30% sodium hydroxide solution that paste agent generally adopts concentration, also can adopt other to have the paste agent of identical effect certainly.Linking agent adopts borax or other linking agent material.
In order to use and convenient transportation; add behind the water pre-gelatinization requirements such as no longer layering about starch according to the present invention; rich starch company limited is weighed in Beijing, and to have produced a kind of model be 8061 pre-gelatinization modified starch; the making method of this modified starch is not the content that the present invention needs protection; when dust-proofing agent of the present invention is made; only need to buy this modified starch; the water that adds weight and be 7～9 times of modified starches in this modified starch stirs and forms water-starch solution; the linking agent that in solution, adds modified starch weight 0.2%～0.6% again, stir.
When the present invention uses, the dust-proofing agent of making packed into have in the container of nozzle, spraying operation is carried out on the stores surface that fine sand soil, backfill soil etc. is easy to airborne dust, per kilogram solution can spray 2～3 square metres of areas, the very fast meeting of dust-proofing agent after the sprinkling is at the stores surface cure, forming the firmer shell of one deck, similarly is to put a coat to stores, can stop stores surface airborne dust pollution on the environment very effectively.
