(54) COMPOSITION FOR THE STRENGTHENING OF EARTHWAYS OF HYDROMELIORATIVE STRUCTURES

J

The invention relates to irrigation and drainage and road construction and can be used in agriculture for combating water and wind erosion, as well as for foiling slopes of engineering structures with hydro-seeding grasses. The known composition of the SE for the strengthening of the earth slope inclusive, wt.%:

Seeds are perennial. grass0

The disadvantage of the known composition for strengthening the land slopes is the weak protective properties of ammonia water as a latex stabilizer in the presence of acidic mineral fertilizers.

The purpose of the invention is to increase the latex coagulation threshold in the presence of acidic mineral fertilizers.

This goal is achieved by the fact that the composition for strengthening the land slopes of irrigation and drainage facilities, including latex, seeds of perennial grasses, mineral fertilizers, mulch material, 25% ammonia water and water, additionally contains sulfite-alcohol bard in the following ratio of components, wt.% : Latex0,5-18,0

Seeds of perennial grasses 0.6-3.0 Mineral fertilizers 1, 0-3.0 Mulching material 9.0-11.0 25% ammonia water 1.0-4.0 Sulfite-alcohol 0.1-1.0 bard The water Sulphite-Alcohol Bard (PRS) is sodium or ammonium salts of lignosulphonic acids — lignosulphonates (LS) formed during the sulphite pulping of the cellulose. Latex emulsion in the presence of SS occurs due to sorption of anionic mole drugs on globules adsorption unsaturated with emulsifier latex. With an increase in the degree of saturation of the surface of globules with a stabilizer, a significant increase in the coagulation threshold of the latex emulsion and its aggregative stability occurs. In contrast to ammonia water, the stabilizing action of which reduces to the occurrence of similar electric charges on particles of latus before and mutual repulsion of these parts.

56.2 04 The PRS creates an adsorption layer with structural and mechanical properties on the surface of the latex globule, whose protective action is many times more effective than electrostatic repulsion. The alkaline environment created by ammonia water (the concentration of which in terms of the ammonia content does not exceed 1.5% neutralizes the excess acidity of the PRS. The composition is prepared as follows. Water is fed into the working capacity of the unit, then ammonium water is introduced into the water and mineral fertilizers, the mixture is stirred with a mechanical blender until they are completely dissolved. After that, the latex emulsion, grass seed and mulch are introduced. Then the mixture is again mixed to a homogeneous composition, Sostay is applied on the surface The structure of the object to be coated is hydroslutant in a single pass of the aggregate Adsorbing on the surface of the mulch and soil particles, the binder forms an elastic, tear resistant and permeable to water and air coating, Table 1 shows the proposed and well-known compounds. potassium and superphosphates} mulch, in addition to sawdust - straw, moss tow, bonfire, The properties of the proposed and known compositions are listed in Table 2

From the data in the table it follows that the use of the PRS in the proposed composition as a latex stabilizer allows the aggregate resistance of the latex to the action of mineral fertilizers to be increased by almost 2 times, and when mixed, almost 3 times compared to the known. In addition, the effective stabilization of latex in the composition reduces the likelihood of clogging of coagulum in the hydraulic pipelines of the hydraulic system and makes the production technology safe by significantly reducing the ammonia content in the composition (up to 20 times). .

Reactive groups present in drugs (-COOH -, - OH phenolic, etc.) increase the ability of latex to bind as a bonding agent.

The use of PRS has a positive effect on soil fertility as a result of its fertilization with cations of salts of lignosulfonic acids and sulfur and also organic matter as a result of humification of lignin,
