Abstract

A chemical sand-stabilizing agent consists of both components with some advantages such as low cost, long duration, no toxicity, odorless and no pollution. The both components are mixed and then sprayed onto surface of sand or mixing them with sand to cover on traveling sand. It costs less with quick operation.

Description

Two component chemical sand fixing materials and sand-fixation method

Technical field

The invention belongs to the control of desert field, more direct a kind of chemical sand fixing material and the engineering sand-fixation method of being meant.

Background technology

At present the chemical sand fixing material that uses is pressed the composition classification, and being divided into is seven classes: 1. silicates, and as silicate of soda, silicate of soda emulsion, potassium silicate, potassium silicate emulsion.2. Aluminosilicates is as clay, peat, cement, blast-furnace cinder.3. lignin is as spent pulping liquor.4. petroleum distillate class is as crude oil, heavy oil, residual oil, pitch and emulsion thereof.5. resinae is as urine formaldehyde resin, phenolic resins, calcium acrylate resin, mylar, polyurethane resin, polyvinyl acetate emulsion, polyacrylamide, polyvinyl alcohol, methacrylate, acrylate.6. latex rubber class is as polychloroprene latex, styrene-butadiene latex, NBR latex, an oily latex.7. plant oil is as cotton seed oil plant, various vegetable oil residue.In these materials, also do not have a kind of material have simultaneously cost low, fix the sand advantages such as the retention time is long, nontoxic, harmless, tasteless, pollution-free.

Present engineering sand-fixation method be adopt resistance, solid, fail, lead four kinds of measures, sand-protecting barrier, fence and air ducting are set fix the sand, efficient is low, cost is high.

Summary of the invention

The object of the present invention is to provide a kind of two-component chemical sand fixation material and sand-fixation method, jump out the circle of existing sand fixation material and sand-fixation method; Adopt two groups of sand fixation materials of A, B to reach that valency is low, the retention time long, nontoxic, harmless, free of contamination purpose, sand fixation material is a liquid, and employing sprinkler or conveyer and pump just can fix the sand.

Technology contents of the present invention mainly is: one group of two component chemical sand fixing materials is water glass (being silicate of soda), another group is organic ester, organic ester comprises that glycol acetate, acetoglyceride, propene carbonate etc. can resolve into the organic ester of acid and alcohol under weak basic condition, and the weight ratio of organic ester and water glass is 1: 5～1: 30.Sand-fixation method has two kinds, and first kind is with two pumps two groups of sand fixation materials to be pumped into blender respectively to mix, and the sand fixation material that mixes is pumped into be sprayed on the drift sand surface in the sprinkler again; Second kind is with two pumps two groups of sand fixation materials to be pumped into respectively in the conveyer, and sand is sent in the conveyer from the another one import and mixed with two groups of sand fixation materials, and three groups of material mixtures that will mix again are covered in the drift sand surface.

The invention has the advantages that: the chemical sand fixing material cost that is provided is low, it is long, nontoxic, harmless, pollution-free to fix the sand the retention time, and the sand-fixation method efficient height, the cost that are provided are low.

Description of drawings

Fig. 1: a kind of embodiment schematic diagram of the present invention;

Fig. 2: another kind of embodiment schematic diagram of the present invention;

The specific embodiment:

Embodiment 1: as shown in Figure 1, water glass in the first sand control liquid basin 1 is pumped in the blender 6 by pipeline 5 by first pump 3, organic esters in the second sand control liquid basin 2 are pumped in the blender 6 by pipeline 5 by second pump 4 and mix with water glass, and the mixed liquor in the blender 6 is sent into spray gun 7 interior atomisations by the pressure of first pump 3 and second pump 4 and flowed 8 and fall into drift sand 9 surfaces and reach and fix the sand purpose.

Embodiment 2: as shown in Figure 2, water glass in the first sand control liquid basin 1 is pumped in the conveyer 10 by first pump 3, organic ester in the second sand control liquid basin 2 is pumped in the conveyer 10 by second pump 4, sand is entered in the conveyer 10 by the husky bucket 11 of storage and is mixed together with water glass and organic ester simultaneously, the sand flow is regulated by control valve 12, and the compound of three components is covered in drift sand 9 surfaces and reaches and fix the sand purpose.

Claims
