Description
Technical field
The invention belongs to desert treatment technical field, more particularly to a kind of fixing the sand for binding agent based on magnesium phosphate cement
Method.
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.China explores solid with plant by the unremitting effort of several generations
The method that husky and mechanical sand fixation is combined, alleviates the invasion and attack of drift sand and the process of desertification to a certain extent.It is wherein mechanical
Fix the sand and typically make 1m × 1m from materials such as wheat straw, stone or clays（Size is different）Grid, formed drift sand harm
Basic protection system.Then psammophytes is implanted into grid（Such as oily wormwood artemisia, sand sagebrush (Artemisia filifolia), hedysarum scoparium, caragana microphylla, arrow-leaved oleaster plant）Formed
Vegetative sand control system.As vegetation coverage increases, sand ground natural conditions environment is improved, and forms the overall natural cover for defense, from
And reach the purpose of preventing and fixing sand.Material major part yet with sand-protecting barrier is wheat straw or straw, and the life-span of its sand-proof is general
It is 3-4 or so, often changes the consuming that straw checkerboard barrier sand-protecting barrier is also brought along in manpower and materials and financial resources.Cubic meter of stone lattice fix the sand barrier be by
Cobble piles 20-30 meters high high of the ridge on sand dune, spacing 1-2 meters, moves towards vertical with wind direction, and its construction of fixing the sand is simple, fixes the sand
Effect is relatively good, however it is necessary that substantial amounts of cobble, long-distance transport building stones etc., high cost, and engineering are needed for desert area
Improvement is provisional measures for sand prevention.The macromolecules such as sediment trapping net or chemical sand-fixing method, Resistance to wind Erosion, water resistance, freeze-thaw resistance
Well, but part macromolecular sand-fixation material is easily decomposed after desert area intensive ultraviolet sunlight, cause secondary pollution.
The content of the invention
It is an object of the invention to provide a kind of based on the sand-fixation method that magnesium phosphate cement is binding agent, to solve existing skill
Preventing and fixing sand material lifetime present in art is short, and high cost, effect are poor and easily cause secondary pollution problems.
The technical scheme that the present invention is provided is as follows：
A kind of is the sand-fixation method of binding agent based on magnesium phosphate cement, it is characterised in that comprised the following steps：
S1, by soluble phosphate, retarded adhesive material, magnesia, filler by weight 1:（0.1~1）:（1~30）:（10~100）Than
Example is prepared and is sufficiently mixed；
S2, s1 steps gained compound and water are pressed by weight（1~10）：1 ratio stirs, and obtains magnesium phosphate cement semi-moist
Material；
S3, by S2 gained the wet feed of magnesium phosphate cement half the husky ridge is piled on sand dune, play a part of preventing and fixing sand.
Further, the soluble phosphate is NH4H2PO4, (NH4) 2HPO4, Al (H2PO4) 3, H3PO4, KH2PO4
The mixture of one or more in the APPs such as (NH4) 2HPO4；
Further, the retarded adhesive material is NaCl, fluoride, soluble fluoride silicate, alkali metal, alkaline-earth metal, borax, boron
The mixture of one or more in acid, borate, sodium tripolyphosphate；
Further, described filler is the mixture of one or more in fine sand, soil, slag or string；
Further；The magnesia is the ore deposit containing oxidation magnesium component after light calcined magnesia, caustic dolomite powder or mineral are smelted
Slag；
Further, the size on the husky ridge is 10-40cm high, 1-4m long, width 1-4m；
Further, the husky ridge is shaped as rectangle or circular or line strip；
Compared with prior art, the present invention has following advantage：
1st, raw material are inorganic material in the present invention, do not cause secondary pollution or destruction to environment, do not cause secondary dirt to environment
Dye is destroyed, and belongs to environmental type desertification control method, and phosphate decomposes can play desert plant fertilizer to a certain extent
Effect；
2nd, because present invention gelling is mutually magnesium phosphate cement, raw material has high corrosion resistance for phosphate（It is saline and alkaline）, high anti-freezing melts
Property, in desert area especially the high and cold, temperature difference is big, salty area has excellent performance advantage；
3rd, because magnesium phosphate cement has good high intensity, workability, rapid curing, corrosion-resistant etc. compared to other chemical adhesives
Advantage, therefore a small amount of magnesium oxysulfide concrete binding agent（Content ＜ 10%）Can just play a part of to fix the sand；
4th, the invention belongs to husky desertification control method, it has both sides advantage:On the one hand, gathering materials on the spot can reduce Desert Sand
The amount of stone；On the other hand, because more than 90% is that desert fine sands are with low cost, construct simple and convenient.Therefore, the present invention is not only sharp
Local Desert Resources are used, cost of defending and controlling sand can be also saved, macroeconomy advantage is highlighted.
