INTRODUCTION
The disinfection of seeds is of paramount importance
in the fight against both gummosis and root rot, for
which various methods of pre-sowing treatment are
used, such as mechanical, physical, mechano-chemical,
chemical and combined methods of processing cotton
seeds. A more effective method is the mechanical-

chemical method of seed treatment of agricultural
crops [1-3]. However, the chemicals used are either
expensive or not effective enough. In this regard, the
development of highly effective, affordable, cheap
chemicals, as well as composite materials based on
local raw materials and production waste used for the
pre-sowing treatment of cotton, is an urgent problem
[4-7].
OBJECTS OF THE STUDY
For the development of composite chemical
preparation,
we
chose
gossypol
resin,
Na-
carboxymethylcellulose (Na-CMC), polyacrylamide
(PAA), caustic soda, soda ash, household water, and
alumak, waste from the production and processing of
non-ferrous metals, as objects of study.
METHODS
The methods used by us to obtain and determine the
physicochemical, as well as technological parameters
of chemical reagent samples using nedal and other
ingredients, as well as drilling fluids based on them, are
as follows: First of all, nedopal and other ingredients
are dried in an oven at 105±5
℃
for 2 hours until the
residual humidity is not more than 2%. Then they are
subjected to dispersion in a grinder (Fig. 1) to a particle
size of 20-50 microns.

Figure 1. Scheme of the installation for dispersing ingredients
The basic principle of operation of the grinder is as
follows: the dried nedopal is fed into the grinder,
consisting of a loading pipe 1, a div 2, a cover 3, inside
of which there is a fixed disk 4 with elements 5 fixed
concentrically around the circumference, a movable
(rotating) disk 6, and mounted on the shaft of the
motor 7. The disk 6 on the end plane contains the
fingers 8, concentrically located around the
circumference of the disk. The disc fingers enter the
gap between the circles of the concentrically located
segments. At the bottom of div 2, there is an exit
window 9. The grinder is mounted on frame 10.

In the grinding process of the nedopal - from the nozzle
1, the material, falling into the zone of the rotating disk
6, is subjected to impact due to the element 5 and
rapidly rotating fingers 8. The nedopal in crushed form
exits through window 9.
Samples of composite chemical reagents containing
nedopal are prepared as follows: 20 grams of nedopal
are weighed on an analytical balance with an accuracy
of ±0.5 g. Then 80 g of powdered chemical reagent
brand KPM-SK-2 based on gossypol resin is weighed.
The weighed components are thoroughly mixed in a
mechanical mortar (Fig. 2) until a homogeneous
powder is formed.
Rod 4 performs arcuate horizontal vibrations, which
ensures good abrasion and mixing of chemicals in the
cup 3. The rod 4 is equipped with removable weights 5,
which provide different degrees of abrasion of
materials.

Figure 2. Scheme of a mechanical mortar
The principle of operation of a mechanical mortar:
various chemicals are poured into cup 3, and mortar 4
is switched on. After thorough mixing and grinding of
the resulting composition, the mortar stops, the cup is
released from the composition and the process is
repeated.
Chemical solutions were obtained during the
installation, the scheme of which is shown in Fig.3. The
plant consists of tank 1, mixer 2, frame 3, valve 4, mixer
drive 5 and loading pipe 6.
The process of preparing chemical solutions is as
follows: a solvent is poured into the loading pipe 6, the
powder is poured, and with the help of a rotating mixer
2, the powder is completely dissolved. When valve 4 is
opened, the finished solution leaves container 1.

Figure 3. Installation scheme for obtaining chemical solutions
From the resulting composition, a sample is taken for
the preparation of chemical solutions. Depending on
the required density, viscosity, fluid loss, degree of
shear stress and crusting thickness, a solution of
various concentrations is prepared at the plant (Fig. 3)
by dissolving in water. A sample is taken at room
temperature in the required amount for conducting
comprehensive studies of the physicochemical and
technological properties of samples of chemical
solutions obtained based on composite chemical
reagents [8-10].
Determination of the physical characteristics of
powder ingredients, and physicochemical and
technological characteristics of chemical solutions
obtained on their basis is carried out using standard
methods, which are discussed below.
CONCLUSION
Technological equipment for the production line for
the production of composite powdered gossypol
preparations for cultivation and cultivation of crops,
including tanks with shutters for bulk mineral
ingredients, a screw feeder with a drive, a grinder for
obtaining a finely divided preparation and a conveyor
packaging line, was prepared and installed.
