Hydrophilic zol-gel coatings for everyday and industrial uses

47.png
Zol-gel method is a technology to produce materials with definite chemical and physical-mechanical properties, including zol production and its successive conversion into gel. Zol-gel conversions need water molecules or non-organic compounds with hydroxyl groups (ОН-), which initiate hydrolysis and polycondensation reactions.

The control unit of the monochromator for pulse spectrofluorometer

14.1.png
The control unit allows to drive a monochromator and to check its position using computer, and also to carry out scanning of spectrum in a automatic mode, that earlier was impossible. This result in simplification of operation of experimenter and exception of the "human factor". The developed universal controller of step motors allows to carry out management of step motors in "two-phase-on" full step mode of excitation of windings.

MEASURING CONVERTER FOR THE IKR ACID AND ALKALI MEDIA TECHNOLOGICAL CONTROL INSTRUMENT

6n.jpg

Measuring converter, which ensures solution of several metrological problems:

·        determination of the type of solution in the pipeline with sequential circulation of 3… 4 types of solutions and foodstuffs;

·        measuring of the temperature of liquid technological media;

·        measuring of the concentration of acting staff in water solution;

·        the exchange of controlling and measuring signals with the base block at a distance of up to 100 m.

Measuring converter for the conductometric measurements is developed on the basis of Atmel AVR microcontroller. Testing signals are generated by DSS method. The modular principle of the construction of measuring converter and the possibility of changing the program makes it possible to realize above metrological tasks with the use of different conductivity and temperature sensors to increase the accuracy of measurement and to exclude the component of error in the communication channel measuring converter - base block.

THE GASES FLOWS CONTROL SYSTEM FOR THE VACUUM-PLASMA TECHNOLOGICAL PROCESSES OF THE FILM COATINGS DEPOSITION (РРС-1000)

11n.jpg

The system consists of the small-size spectrometer (S100) and the conjugation device which are connected to the personal computer and also the software. The execution units of the system are the electrically controlled leaks and valves. The system operation is based on the real-time registration of the emission spectrum of the plasma discharge with the assistance of S100 spectrometer, the computer processing of the spectrum with the computer software assistance, the control signals delivery to the leaks of the working gases using the conjugation device. The system controls the gases flows in such way that the predetermined chemical composition of the deposition flow (the forming coating) and the pressures of the working gases are kept constant during the technological process and during its repeat.
