Abstract

The invention discloses an MB type soil curing agent capable of rapidly governing sand dust in a large area with a low cost. Firstly, for the technique development history, the product is continuously perfected and improved from the nineteen seventies to the nineteen nineties; secondly, for the environment-friendly property and security property of the curing agent, the MB type curing agent is a high-technique novel environment-friendly safe product without secondary pollution, is free of toxicity, harm and secondary pollution, and is a material which meets the internal TCLP (Toxicity Characteristic Leaching Procedure) environment-friendly testing standards; thirdly, the curing agent can govern sand and prevent dust in a large area, and the soil which is cured by using the MB type curing agent has the capability that the anti-seepage capability and the integrality of the soil are enhanced, and flying dust caused by windstorm, frost crack and frost boiling are effectively prevented; fourthly, for the construction cost of the curing agent, the sand is governed and the dust is prevented in a large area, twenty to twenty-five parts of water and one part of the curing agent are mixed together (the ratio is determined according to specific sand) to form a thin shell which is hard on the surface and is air-permeable, plants can grow without harm, and the sand is not lost to expose the roots in windstorm. The MB type soil curing agent is applied to highway and railway slope protection and desertification control, and the construction cost is very low.

Description

A kind of energy fast, big area, with low cost, the MB type soil-solidified-agent of administering sand and dust

Purposes: administer in the engineering at drift sand and the ground that desertifies, adds directly sprinkling use behind the 20-25 times of aqua, make the desert restore vegetation, resist wind speed, eliminate sandstorm, its hold-time is more than the several years.

Technical background: MB type soil-solidified-agent product, major advantage is: 1, the sandy soil of grain pattern, be transformed into reticulated structure; 2, impel the growth of plant root whisker; 3, nontoxic non-secondary pollution; 4, one of energy percentage hundred absorbs moisture, can retain 20% of steam output simultaneously; 5, increase the roughness on ground, the decades of times that resists wind speed is to hundreds of times.Built vertical Demonstration Base reaches good effect more than 5000 mu on the Inner Mongol, Gansu and other places, obtains to promote behind the appraisal of scientific and technological achievements certificate in 2007, in November, 2011 promotion effect has been passed through evaluation, and the suggestion large-scale promotion.

Production Flow Chart: the mixing of polypropylene copolymer and portions additive.

Protection core: the utilisation technology system of the mixing of polypropylene copolymer and portions additive, this product.

One, innovative idea---the creationary contribution of project technology:

Sand storm problem for the ground that desertifies; the reference U.S. the seventies extensive spray chemical substance after; experience in the curing of sandy land surface conjunctiva; on the basis of the sand-fixation agent that improves with keen determination the U.S. and Japan; invented a kind of BEC sand-fixation agent and relevant spray application that is suitable for the NW China climatope; through the Inner Mongol, the field trial demonstration proof on the ground such as Gansu, Ningxia; spray chemical material and can form very thin porous-film at sand ground; infiltration and sand not also plays an important role for the protective plant root system.The demonstration area reaches more than 5000 mu.

This project main achievement is to make BEC type soil-solidified-agent (agent of sand ground vegetation protection) obtain further popularization.We are at the Alashan Area, inner Mongolia Autonomous Region Tengger desert, in Siziwang Banner national defence highway both sides side slope, and the Jungar Banner coal field covers damaged face test site, have carried out nearly natural patches and have sprayed demonstration, also provide model for respectful province defends and controls sand with ecological construction.Set up patch structure and the collocation form of nearly nature, reasonably utilize the sand ground resource, set up chemical sand-fixing and the biological sand control innovation mode of defending and controlling sand and combining.By to the assembling of prior art and achievement, supporting and integrated, on different soil types, according to its different purposes, make its expansion utilize the space.Follow the natural, ecological rule, promote BEC type soil-solidified-agent to sand ground, salinization land, Grassland desertification ecosystem sand control technique, the linear protection in national defence highway both sides and on Dunhuang, Minqin County and other places, corresponding match technology means has been proposed, and the mining area is covered on the application problem of damaged face Revegetation, the scientific and technological achievement of MB type soil-solidified-agent is promoted and demonstrated, will enrich and widen novel material and new approaches that China defends and controls sand, significant to China's desert treatment.
