Similar technical solutions are known. For example, in the patent RU No. 2073044 (examples 3, 4, 5) describes the mass of particles of vegetable raw materials for the manufacture of limnogeology plastic in the form of a mixture of crushed particles of peat moss group, and pine wood, passed through a sieve with apertures of 3 mm, with the ratio of components (wt.%):

particles of conifers.

The General characteristics of the analog and offer masses of particles of vegetable raw materials for the manufacture of limnogeology plastic on the rest of the options are

particles of wood.

The technical result, which is impossible to achieve this analogue is superior allocation of components of a mass of particles of plant materials, the necessary and sufficient number of active natural connected to the th, forming binder to obtain limnogeology plastic.

The inability to achieve the technical result vysokorelevatnym analogue is a high density of crushed particles of peat and pine wood, the selection of which is necessary and sufficient number of active natural compounds for the formation of the binder requires a higher temperature of the mass of particles of vegetable raw materials in the manufacture limnogeology plastic.

Known analog adopted for the prototype, is the mass of particles of vegetable raw materials for the manufacture of limnogeology plastic that is described in the abstract Kartashova I.E. Development and implementation of technology for lignouglevodnyh plastics of shredded green waste". ULTI Sverdlovsk. 1968 (page 6, 21), which includes:

particles of wood.

Common features of the prototype and the proposed technical solutions for the eleventh var is the ant mass of particles of vegetable raw materials for the manufacture of limnogeology plastic are

The technical result, which cannot be achieved by the prototype is improved allocation of components of a mass of particles of plant materials, the necessary and sufficient number of active natural compounds forming binder to obtain limnogeology plastic.

The inability to achieve a prototype of the above technical result is the increased proportion in mass of particles of vegetable raw materials for the manufacture of limnogeology plastic, dense wood in the form of particles of crushed branches and tops of coniferous trees.

As lignouglevodnyh plastics from the particles of the powdered plant materials based on the ability of the active natural compounds that fills the intracellular space and the capillary cavity cellulose skeleton plants, converted into a binder, enveloping and firmly connecting the cellulose particles, when exposed to temperature and pressure, excessive content of dry wood particles in the mass of particles of vegetable raw materials for the manufacture of limnogeology plastic reduces the total content of the active natural compounds, makes a lot hard and requires a higher temperature for separation of components of a sufficient number of these substances is in the process of thermoprotei mass in limnogeology plastic.

The above technical result according to the first variant of the mass of particles of vegetable raw materials for the manufacture of limnogeology plastic is achieved by the fact that the mass contains finely dispersed particles of needles and bast bark of coniferous branches in the following ratio of components (wt.%):

particle needles 0,5÷99,5; particle bast bark of 99.5÷0,5;

as the experiments showed, needles and bast bark of coniferous branches, having less density than wood, contain relatively more active natural compounds in the form of resins, lignin, carbohydrates, and other,

what contributes to the allocation of a sufficient number of components of the mass during its thermoprotei, by heating the mass to a temperature significantly lower than in similar technical solutions, transformation of these compounds in the required amount of binder, enveloping them durable cellulose particles and after hardening of the binder allows you to get limnogeology plastic in the form of plates or other termopresmash products.

Also found that the particle content of pine needles over 99.5 wt.% reduces the plasticity of the mass and requires an increase in humidity, which leads to longer drying obtained from mass products, their variances, and the particle content of the needles is less than 0.5 wt.% reduces the resistance obtained limnogeology layer is ka,

the particle content of bast bark over 99.5 wt.% reduces the resistance obtained limnogeology plastic, and when the content of particles of bast bark less than 0.5 wt.% need a higher humidity mass.

In addition, it was found that the optimum mixing ratio of the mass of particles of vegetable raw materials for the manufacture of limnogeology plastic determines the type of coniferous vegetation, from which the components of the mass, location and growing conditions, method and time of procurement of raw materials and storage conditions - many factors, depending on the number and activity of contained in the components of complex natural compounds, this leads to the variation of the optimum ratio of components of the mass within the specified limits.

The test results of samples (see table No. 1)made under extreme limit and the intermediate component content of the first variant of the mass of particles of vegetable raw materials for the manufacture of limnogeology plastic at low temperature, show that the composition of this variant mass can thermoprotei mass, when it is heated to temperatures significantly lower than in similar technical solutions, get limnogeology plastic in the form of plates and other termopresmash products with high physical-mechanical is Kimi characteristics.

All the above confirms the achievement of the technical result of the above, under the first option.

The technical result of the above, according to the second variant of the mass of particles of plant materials to obtain limnogeology plastic is achieved by the fact that the mass contains finely dispersed particles of needles, bast bark of coniferous trees and timber, in the following ratio of components (wt.%):

particles needles 0,5÷98; particles bast bark 0,5÷98; particles of wood 1÷43, as wood mainly consists of strong cellulose fibers, particles reinforced mass and help to increase the strength of the resulting limnogeology plastic

when the content in weight of the particles of plant material, of wood particles less than 1 wt.% the strength values obtained limnogeology plastic decreases and the particle content of the wood more than 43 wt.% makes a lot hard and requires a higher temperature to allocate the required number of active substances.

In addition, it was found that when the particle content of the needles more than 98 wt.% need a higher humidity mass, which leads to longer drying of the products obtained, their variances, and the particle content of the needles is less than 0.5 wt.% reduces the resistance products,

the particle content of bast bark more than 98 wt.% reduces water resistance and strength developed the CSOs limnogeology plastic, and the content is less than 0.5 wt.% reduces the plasticity of the mass and requires an increase in its moisture content.

The test results of samples (see table No. 2)made under extreme limit and the intermediate component content of the second variant of the mass of particles of vegetable raw materials for the manufacture of limnogeology plastic at low temperature, show that the composition of this variant mass can thermoprotei mass of plant material when it is heated to temperatures significantly lower than in similar technical solutions to select from components a sufficient number of active natural substances to convert them into a binder, to envelop them included in the solid cellulose particles and, after hardening of the binder to obtain limnogeology plastic in the form of plates and other termopresmash products with high physical-mechanical characteristics.

To obtain the mass of particles of vegetable raw materials for the manufacture of limnogeology plastic and proposed technical solutions do the following:

take vegetable raw materials with natural humidity of at least 60%, in the composition and proportions specified in the proposed mass of the particles of plant material, for producing limnogeology plastic;

crushed plant material and get a lot of particles of vegetable raw materials for the manufacture of limnogeology plastic by known methods, for example, with the use of hammer crushers,

receive particles of the fibrous structure, the dimension of which is set installed in the crusher bars. So, when using a grating with slit-like holes, width not more than 1 mm, a length of 30-50 mm, receive particles mainly iglove the Oh (filiform) form, the dimension which determines the ratio l/d=5-100,

where t is the length of the particle, d is the average diameter of not more than 1 mm.

The use of such particles in the mass for the manufacture of limnogeology plastic allows you to boost the strength of the products obtained, especially bending strength, due to the greater area of adhesion of particles with a binder.

To confirm the above technical result and the possibility of using the proposed variants of the mass to a specified destination were manufactured and tested samples according to GOST 10632-89.

Humidity weight ranged between 17-40%.

The results are given in tables 1-11 when the following notation:

1 - Density (kg/m3); 2 - tensile strength in bending (MPa);

3 - Water absorption (% in 24 hours); 4 - Swell (% per 24 h);
