Description
Technical field
The invention belongs to desert treatment technical field, more particularly to a kind of magnesia oxychloride cement sill, preparation method and
Its application in preventing and fixing sand.
Background technology
China is one of more serious country of desertification hazard in the world, and desert treatment is received as an important state basic policy
To great attention.The key of desert treatment is preventing and fixing sand.The major way of control of desert is that physics fixes the sand both at home and abroad at present
（Such as cubic meter of stone lattice, earthwork lattice）And sand consolidation with biologic（Such as serike）.It is common several to fix the sand mode for example：Straw checkerboard barrier sand-protecting barrier is to use
The materials such as wheat straw, straw, reed are bundled into grid-like windbreak on moving dunes, to weaken the erosion of wind-force.Straw checkerboard barrier is husky
Although barrier low cost, construction are simple, the efficiency high of preventing and fixing sand.Yet with sand-protecting barrier material it is most of be wheat straw or straw,
The life-span of its sand-proof is generally 3-4 or so, often changes the consumption that straw checkerboard barrier sand-protecting barrier is also brought along in manpower and materials and financial resources
Take.The cubic meter of stone lattice barrier that fixes the sand is that cobble is piled on sand dune 20-30 meter high high of the ridge, and spacing 1-2 meters, trend is vertical with wind direction,
Its construction of fixing the sand is simple, and sand-fixing effect is relatively good, however it is necessary that substantial amounts of cobble, building stones of transporting for long-distance are needed for desert area
Deng, high cost, and engineering control is provisional measures for sand prevention.The macromolecules such as sediment trapping net or chemical sand-fixing method, weather-proof energy
Power, water resistance, freeze-thaw resistance are good, but part macromolecular sand-fixation material is easy after desert area intensive ultraviolet sunlight
Decompose, cause secondary pollution.
The content of the invention
It is an object of the invention to provide a kind of new magnesia oxychloride cement sill, preparation method and its in preventing and fixing sand
In application, it is short to solve preventing and fixing sand material lifetime present in prior art, high cost, effect difference and easily cause secondary
The problems such as pollution.
The technical scheme that the present invention is provided is as follows：
A kind of magnesia oxychloride cement sill, it is characterised in that be made up of following components：Magnesia, fine sand, bischofite and water.
Further, described magnesia oxychloride cement sill each component is by weight ratio：Magnesia, fine sand, water chlorine magnesium
Stone and water=1：（1~30）:(0.5~4): (0.5~3).
Further, described magnesia oxychloride cement sill each component optimum proportioning by weight is 1：10:1.5:1.3.
A kind of magnesia oxychloride cement sill fixes the sand the preparation method of plate, it is characterised in that comprise the following steps：
S1, by bischofite（MgCl2·6H2O）With water（H2O）It is made into the magnesium chloride solution that Baume degrees is 15 ~ 32Be ';
S2, by s1 steps gained magnesia, fine sand, magnesium chloride solution ratio 1 by weight：（1~30）:(1 ~ 7) is mixed to form chlorine
Oxygen magnesium cement concrete material；
S3, will magnesia oxychloride cement concrete material import tabular mould in conserved, the demoulding is made after slurry solidifies completely
Fixed the sand plate into magnesia oxychloride cement sill.
Further, the size of tabular mould is in the step s3：Length × width × height=1m × 0.2m × 0.025m.
A kind of new magnesia oxychloride cement sill fixes the sand application of the plate in preventing and fixing sand, it is characterised in that will be above-mentioned
The magnesia oxychloride cement that method the is made plate that fixes the sand is arranged on Shamian Island by the form of ten grids, plays a part of preventing and fixing sand.
Compared with prior art, the present invention has following advantage：
1st, magnesia of the present invention is formed by magnesite or dolomite mineral calcining, and filler takes from desert fine sands, material materials
It is convenient, and 80% be fine sand in material, can gather materials on the spot, the cost of preventing and fixing sand greatly reduces；
2nd, magnesia oxychloride cement sill wind erosion ability of the present invention, water resistance, cold-resistant anti-freezing property are excellent, usage cycles
It is long, do not result in secondary pollution；
3rd, magnesia oxychloride cement sill of the present invention fix the sand plate manufacture craft it is simple, it is not necessary to large-scale equipment, production
Cycle is short, easy for installation, preventing and fixing sand effect is good；
4th, magnesia oxychloride cement sill of the present invention fix the sand plate be installed on desert surface formed cross grid form, take up an area
Area is minimum, and the growth of the intrinsic plant in desert is not influenceed, the combination for answering this chemical sand-fixing and physics to fix the sand, and not only secures stream
Sand, and the growth of plant is maintained, improve ecological environment；
5th, magnesia oxychloride cement sill of the present invention has weatherability, anticorrosive, weathering resistance, power than other sand prevention materials
Function admirable is learned, strong, the attractive in appearance advantage of globality is installed；
6th, higher level, compression strength are attained by by testing fix the sand plate material compression strength, rupture strength of magnesium cement>
13MPa, rupture strength>2MPa.
