Description
Technical field
The invention belongs to ecological environment treatment technical field, particularly a kind of preparation method of sand control brick and desertification control method thereof.
Background technology
In recent years, sandstorm was becoming increasingly rampant, and the whole nation has 1500 kilometers of railways, 30,000 kilometers of highways and 50,000 kilometers of feed ditch to cause destruction in various degree due to hazards of sand storms.The direct economic loss that China causes because of hazards of sand storms every year reaches 54,000,000,000 yuan, is equivalent to 3 times of provinces and regions, northwest 5 fiscal revenues in 1996.Such as, in in by the end of February, 2013, a strong wind, the madness of sandstorm is attacked, and allow whole Jing-Jin-Tang Region dirt Sramanera overflow, reporter sees, the row of the street employs various protective gear: mouth mask, full head-shield, polybag protect, the pedestrian waited for bus in roadside, has been filled up by sand in whole nostril and face, has been in dyspneic state.The same day, the Environmental Monitoring of Beijing official showed, and PM10 instantaneous value in Pekinese is close to 1000.
Over nearly more than 40 years, desertification is very serious in China, and the trend expanded further is fairly obvious.According to statistics, from the 1950's to the seventies, soil, China desert expands with the speed of average 1560 square kilometres, entered for 20 end of the centurys, annual expansion 2100 square kilometres, predict that the development speed with 1.32% expands by 10 years from now on desertifications, the soil becoming desert every year on average will reach 2370 square kilometres, land resources is reduced very severe day by day, desertification is China's ecological environment problem that particularly west area is the most outstanding, not only seriously affect and annoying this district's industrial and agricultural production and socioeconomic sustainable development, and govern the sustainable development in surrounding area and even the whole nation.In Implementation of Western Development process, the top priority of chemistry pollution prevention Ying Shi China Eco-environment Construction of Western Region.
Technical method at present for sand prevention is also little, and sand control mode comparatively conventional at present has mechanical engineering to fix the sand, vegetative sand control, chemical sand-fixing.But these modes of fixing the sand have certain defect, it is short that the cycle is fixed the sand in such as mechanical engineering, can only as the provisional auxiliary means of fixing the sand of one; Vegetative sand control survival rate is lower; Chemical sand-fixing cost is high and have certain pollution to environment.The most frequently used method is planted trees exactly, expands vegetative coverage area to reach the effect of sand prevention.Be exactly overlay film sand prevention in addition, utilize plastic sheeting to desert and carry out technology covering with desertifying, making the grains of sand not by wind waved and movement, have again the effect of higher water-retaining sand-stabilizing simultaneously.But because desert and desertification ground area are too large, cost is too high, and this method should not be carried out, and at present, overlay film sand prevention is not widely used among reality.Not only can solve the increasingly serious problem of desertification with the method for husky sand control, and greatly reduce cost.Novel sand control brick adopts the theory of " with husky sand control ", and raw material adopts local dust storm, while slowing down Sand Movement speed, protecting existing soil, also significantly reduces cost of production.Be the problem that China one of facing is large with the sand control of sand control brick, sand control Zhuan Yeshi China studies a more direction now, utilizes dust storm to make sand control brick, realizes with husky sand control, cost-saving, increases Feasible degree always.This certainly will will attract the sight of more researchers.
Summary of the invention
The object of this invention is to provide a kind of preparation method and desertification control method thereof of sand control brick, be characterised in that, the making of described sand control brick is gathered materials on the spot, sand control brick is prepared after utilizing dust storm to mix with water glass, kaolin and gypsum, not only cheap, and practical environmental protection, concrete preparation process is as follows:
1) full sized brick is made: will according to mass ratio, kaolin 1.6-2.5g and gypsum 1.6-2.5g is added in every 100g dust storm, fully be uniformly mixed, the amount adding water glass by every 100g dust storm is while stirring 16 ~ 25ml, mixed slip put into mould and flattens, then putting into 30 ~ 60 DEG C, baking oven and dry 4 ~ 10h;
2) shaping: the full sized brick after drying completes sprays waterproof agent; After its drying drying at room temperature atmosphere under maintenance about 1 week.
Described modulus of water glass is 1.5 ~ 2.5.
Described waterproof agent is the benzene emulsion of 10wt% solid content and the organic silicon emulsion of 5wt% solid content, and every block full sized brick sprays 5ml.
Described sand control brick is circular, oval or polygon, and thickness is 5mm-50mm.
Described desertification control method adopts in the mode of husky sand control, sand control brick is utilized to lay novel sand control brick or the husky brick of planting plants combination paving by desert areas subregion building paravent with at desert surface and Arid Desert Region, cover desert surface, the novel sand control brick laid can prevent strong wind from sweeping sand and dust, rainwater can be permeated again, keep the humidity of surrounding plants soil, improve vegetative sand control survival rate, and in conjunction with Arid Desert Region afforestation, building paravent; Thus reach with husky sand control, cost-saving object.
The invention has the beneficial effects as follows that the making of this sand control brick is gathered materials on the spot, not only cheap, and practical environmental protection; The present invention adopts in the mode of husky sand control, sand control brick is utilized to lay novel sand control brick covering desert surface by desert areas subregion building paravent with at desert surface and Arid Desert Region, the novel sand control brick laid can prevent strong wind from sweeping sand and dust, rainwater can be permeated again, keep the humidity of surrounding plants soil, improve vegetative sand control survival rate, thus reach with husky sand control, cost-saving, increase the object of Feasible degree.Utilizing is solve this problem expensive with the feature of husky sand control, and the cycle of fixing the sand long, not easily covered by dust storm, and environmentally safe.Produce in enormous quantities, extensive use.
