Description
DESCRIPTION OF THE INVENTION
WAY OF MIXING OF LIQUID SUBSTANCES
FIELD OF INVENTION
The invention relates to technological chemical processes and can be used for synthesis of different substances (including those of very thick consistency) found in a liquid phase, for example, in manufacturing of mastics, glues, compounds, viscous lubricants, motor oils, varnishes, paints and others, namely, in processes, where mixing of several substances is required to obtain a product with predetermined properties.
BACKGROUND OF THE INVENTION
The closest to the present invention by technical essence and achieved effect is way of mixing of liquid substances which is essentially mechanical blending [1J, accomplished through use of mechanical blender outfitted with blades and arranged within a reservoir ;
the latter is equipped with a jacket conceived for its water and steam heating. The mixing of substances is accomplished concurrently with their heating to predetermined temperature which is maintained until such mixing is ended, which process may take up to a few hours to carry out.
The limitations of the said way include high power consumption and low productivity caused by long run of technological processes. For example, in the said way the required temperature can only be attained after two hours since heating has been started up; and it takes from two to eight hours of mixing to attain required properties in a product depending on the constituents of the compound.
The present way is conceived to increase efficiency of mixing liquid substances by reducing the time needed for a full run of technological processes as well as lowering of power consumption, while gaining in quality of the final product. This task is completed through combination of essentially mechanical mixing with electromagnetic microwave radiation treatment of the mixed substances with frequency rate of 0.1-300 GHz and field density of 0,1 V/cm up to 100 V/cm depending on the molecular structure of the latter.
If uniform distribution of substances being mixed is attained in a total volume (not to mention some other necessary preconditions), the synthesis will take place which allows to obtain a steady-state product with known properties. As a matter of fact, mixing is made possible due to mutual dissolution of mixed substances.
As will be recalled from physics, all substances are comprised of atoms and molecules influenced by intermolecular forces of attraction and repulsion. Dissolution of substance A in substance B is only possible if intermolecular attraction forces FAA and FBB, serving to link particles of substance A with those of substance B, are overcome by forces FAB
made apparent at dissolution of the said substances.
If forces FAA H FBB prove to be much stronger than force FAB, no uniform molecular distribution will occur which means dissolution has failed [2].
It follows, to dissolve one substance within the other, there should be attraction strong enough between dissolved substance and the solvent, or the conditions should be created under which forces FAA and FBB decrease as force FA increases.
In many technological processes it is achieved through increase of temperature of mixed substances. Besides, many substances are subdivided into polar and nonpolar substances, that is comprised of either polar or nonpolar molecules [3].
Molecules in polar substances, owing to asymmetrical distribution of charges, are imparted a constant dipole moment, which means they are dipoles.
In nonpolar substances the distribution of charges in molecules is symmetric, so they are devoid of dipole moment. However under action of an external force field (for example, electrical) the symmetry of distribution of charges in molecules is broken, and they get induced dipole moment. This phenomenon is referred to as polarizability.
In polar substances the dipoles are aligned with an external field. If variable external field is superposed on mixed substances, the dipoles of polar molecules and induced dipoles of nonpolar molecules will follow change of direction of external field. At certain frequency and power of external field, conditions are created when the forces of an intermolecular attraction F~, and FBB will weaken, while forces FAF, will grow at the expense of the force of an external field.
As a result, there is no need to heat the mixed substances to cause synthesis.
The minimal temperature of the mixed substances should ensure homogeneous distribution of components in a volume at mechanical mixing.

As a result, there is no need to heat the mixed substances to cause synthesis.
The minimal temperature of the mixed substances should ensure homogeneous distribution of components in a volume at mechanical mixing.
The frequencies proper to fluctuations of molecules of many substances are known [3] to be within range of ultrahigh frequencies of 0.1 GHz to 300 GHz. The closer to the frequency of molecules' fluctuations the external field frequency is, the more efficient the action of the field upon molecules becomes which translates into greater degree of change of intermolecular interaction thus speeding up the process of synthesis.
The effect of synthesis caused by microwave field will occur to some extent in many mixed liquids. It can be explained by the fact that the above said effect is based upon classic model of atomic and molecular structure of the substance and that interaction between atoms and molecules occurs as a response to discrete change of energy state of their exterior electron shells as it is described in quantum mechanics.
The energy of external electromagnetic microwave field contained within mixed substances allows for faster and easier change of state of electronic shells of different atoms and molecules bringing about their steady connection - synthesis.
EMBODIMENT OF INVENTION
The way of mixing liquid substances can be described as follows. For example, to obtain motor oil, base oil is poured into a boiler [ 1 ] conceived as a capacity of 2000 liters, which is equipped with a mechanical blender with blades. Then 6 to 10 types of additives is added in compliance with instructions, whereupon mechanical mixing is started.
After a while, when all the additives are uniformly distributed within the volume of base oil, microwave radiation is activated. It is by experience that optimal value for time and type of action are determined for each brand of final motor oil product.
This way can be illustrated as follows. The base oil with additives (in compliance with the instructions), contained in plastic vessels of 0.12 and 3 litres, was placed inside a chamber of capacity of 25 to 30 litres, where it was subjected to the action of microwave radiation of 2450 MHz with electric field strength of E of 0 to 24 V/cm. Immediately before its placement in the chamber, the oil with additives was mixed by shaking and stirring it up for 10 seconds.
To determine how strength of electromagnetic field E influences the process of mixing of base oil and additives, experiments have been carried out in a wave guide chamber.
A glass test tube with volume of 50 ml, filled with base oil and additives, which were mixed up beforehand by a glass stick for 10 seconds, was placed in the middle of the wider wall of the wave guide. By way of changing the output power of the generator, a target value of electromagnetic field E was generated in the glass test tube filled with oil.
All respective results are shown in Table I .
As can be deduced from the table, the way the additives are dissolved in a base oil, being exposed to the action Qf a microwave field, is practically independent from initial as well as final temperatures of the mixed components. If strength of field E is less than 1 V/cm and more than 100 V/cm , discrepancy between properties of the oil and the requirements of the standard are observed.
A new way of mixing of liquid substances, if compared to the old one, has following advantages:
- reduces total time of mixing by a few hours;
- reduces power consumption by more than 10 times;
- improves quality of mixing;
- no heating is required which is especially important for mixing highly flammable liquids.
