Description
Technical field
The invention belongs to sand fixing technology fields, and in particular to a kind of sand-consolidating agent and preparation method thereof.
Background technology
Desertification is the great ecological problem in the whole world and China's life the most serious for influencing human survival and development
State problem.Not only area is big for China's desertification, has a very wide distribution, and endangers seriously, has a far reaching influence.Desertification destroys ecological ring
Border threatens human survival：1）Sandstorm brings serious pollution to atmospheric environment.2）Desertification makes biological quality deteriorate, and species are rich
Degree reduces, and constitutes a serious threat to bio-diversity.3）Desertification destroyed land resource makes to reduce using soil, under quality
Drop causes the agriculture-stock production underproduction even to have no harvest.In addition, desertification also usually does great damage to water conservancy projects, such as silt
Reservoir, pile things on feed ditch etc. are invaded, agricultural production is affected.Meanwhile after silt largely enters river, also make bed accretion,
Constitute the hidden trouble that river levee bursts.Therefore, it defends and controls sand, concerning the survival and development of the Chinese nation, pacifies concerning Global Ecological
Entirely.
Desert treatment has become global problem, prevents Desert Expansion, afforestation desert has become the 21 century mankind and strives for
Living environment, the matter of utmost importance for expanding living space.
Aeolian sandy soil " leak leakage fertilizer " nutrient content is low, and presently disclosed sand-consolidating agent is most simple to fix the sand, only
Aeolian sandy soil can be fixed within the regular hour, can not fundamentally change the physicochemical property of aeolian sandy soil, restore the life of soil
Production capacity power.Therefore, while fixing the sand, aeolian sandy soil soil fertility can be improved, change the physicochemical property of sandy soil, accelerate aeolian sandy soil to
The transformation of soil is with regard to very necessary.
Oil shale (oil shale) is a kind of sedimentary rock containing organic matter, and it is 2,400,000,000 tons that resource has been verified in China.With generation
The resources such as boundary stone oil, natural gas are increasingly in short supply, and oil shale utilization are growing, and low grade oil shale and lime-ash are oil shales
The discarded object of power boiler discharge of industrial discharge, a large amount of low grade oil shale and lime-ash are piled into mountain, do not only take up a large amount of soils, and
And also need to put into a large amount of maintenance fund every year, while doing great damage to the ecological environment on periphery.Low grade oil shale
And not only contain a large amount of and Meso- and micro-nutrients necessary to abundant organic matter and plant growth in lime-ash, but also through destructive distillation
Lime-ash afterwards also has porous structure, there is certain retain water and nutrients function.
