Abstract
The present invention discloses an atomizing agent for controlling flyash, sand flying and the sand flying of a sand dust storm. The present invention is composed of soil, hydrocellulose, yellow clay, cotton pulp, pre-gelatinized starch, PVA and water. The components are prepared into emulsion in proportion after separately ground, dried, hydrolyzed, etc. according to the characteristics of each component. The face of a treated object is constructed by an atomizing method so that a solidification protective shell layer is formed, and then, the aim for controlling sand flying is achieved. The present invention has the advantages of no poison and abnormal flavour of the used raw materials, biologic degradation, low price, easy obtaining, simple construction, no pollution production, high treatment speed, cost saving and favourable effect.
Description
Technical field
The present invention relates to a kind of environmental protection filming agent, is a kind of propellant of dirt and preparation method thereof that fixes the sand, consolidates specifically.
Background technology
Environment protection is human survival and the severe challenge that faces of development, and wherein desertification of land and consequent sandstorm have had a strong impact on arid geographic ecotope short of rain, and the mankind's life and Economic development brought tremendous loss.The reason that causes sandstorm is the variation of global climate on the one hand, the increasing etc. of climate warming, arid, strong wind weather, and this is the wind regime that produces sandstorm; On the other hand, people's the excessive reclamation of wasteland, herd and cause vegetation deterioration, deterioration of grasslands, thus the meadow of Sha Huaing, the ground of ploughing, lay idle, the river cutout is dry and lakebed mud mummification etc. just becomes the important sand and dust source of sandstorm.In addition, in people's economic construction activity, places such as exposed workyard and building waste, municipal wastes, exposed coal, powder, ash, also " reentrainment of dust " for sandstorm provides the dirt source.
In order to control sandstorm, kick up in the husky source that particularly intercepts sandstorm, and people have adopted many methods, as sand-protecting barrier, the careless lattice in the side of beating, chemical products covering, water spray pressure dirt etc. are set.Suchlike method has obtained certain effect more or less at regional area, but certain limitation is all arranged.For example, sand-protecting barrier, the careless lattice in the side of beating etc. are set to be needed a large amount of manually, though Master Cost is low, the construction comprehensive cost is big, and weak effect, take effect slow; Chemical products covering meeting causes new pollution to ecotope; Water spray is pressed the dirt weak point of holding time, and can only use in the city temporarily.Their topmost defectives are to block drift sand, cut off the sand and dust source, therefore can not fundamentally solve the sand and dust source problem of sandstorm.
Summary of the invention
The purpose of this invention is to provide a kind of effectively Feng Shagu soil, cut off the sand and dust source, thereby control sandstorm but the propellant that can not pollute environment.
Another object of the present invention provides the making method of The propellant.
The objective of the invention is to realize by following technical scheme.
A kind ofly control the propellant that airborne dust, sand, sand devil sand dust are kicked up, it makes (weight unit, down with) by following component:
Yellow clay 16-76 cotton pulp dregs of rice 8-38
Pre-gelatinized starch 5-35 polyvinyl alcohol 10-50
Water 1000
When this propellant be used for urban construction working-yard, building waste, municipal wastes, exposed coal, powder, when ash waits aheap, its component also can be done following selection:
Soil 15-35 hydrocellulose 10-13
Yellow clay 16-36 cotton pulp dregs of rice 8-10
Pre-gelatinized starch 5-20 polyvinyl alcohol 10-30
Water 1000
When this propellant is used for sandy bare land, dry Shahe beach, the ground of laying idle etc., above-mentioned propellant, its component also can be done following selection:
Soil 28-58 hydrocellulose 12-18
Yellow clay 18-59 cotton pulp dregs of rice 9-20
Pre-gelatinized starch 15-25 polyvinyl alcohol 18-40
Water 1000
When this propellant was used for the staggered band of desert edge, mobile sand, sand dune, agriculture and animal husbandry, desertification grassland etc., its component also can be done following selection:
Soil 30-75 hydrocellulose 16-25
Yellow clay 50-76 cotton pulp dregs of rice 18-38
Pre-gelatinized starch 20-35 polyvinyl alcohol 25-50
Water 1000
The method of above-mentioned each component being made propellant is:
1. get
Soil is dried and crushed into the 180-200 order;
2. hydrocellulose is made by the diluted common acid hydrolysis of natural cellulose (cotton stalk, cornstalk, wheat straw etc.);
3. get the yellow clay under the face of land, through crushing screening to 180 order, heavy wash rice, drying is made meal;
Linters through boiling, wash, remove sand, pull an oar, dewater, drying makes the cotton pulp dregs of rice;
5. adopt atomization to prepare pre-gelatinized starch, in continous way jet cooking device with high pressure steam with the rapid gelatinization of starch milk, spraying drying makes then; Perhaps adopt extrusion process to prepare pre-gelatinized starch, the starch that will be transferred to contains moisture 15-20% adds in the extrusion machine, is that the aperture high pressure of 1-10mm is extruded through the aperture, through pulverizing 180 mesh sieves.
6. polyvinyl alcohol is the white powder resin, is got by the Vinyl Acetate Copolymer hydrolysis;
7. with the reasonable proportioning of above-mentioned each component warp, be medium, fuse together cmpletely that being prepared into the suspension emulsion can implement with the normal-temperature water.
The propellant that sand devil sand dust is kicked up of controlling by the present invention's making, can impose on the operational level by facility or mechanical means atomizing, solidify one of back formation and have certain intensity and flexible protection shell, intercepted the husky source that forms sandstorm, stablized Shamian Island, on sand dune and blowland, setting up the artificial vegetation and recovering natural vegetation and created stable ecotope.The present invention adopts is nontoxic, free from extraneous odour, raw material biodegradable, cheap and easy to get, and constructional method is simple, easy to operate, and the production preparation process is pollution-free, and improvement speed is fast, and cost saving is effective, is a kind of technology of compliance with environmental protection requirements.
Embodiment
