THE INCREASING FILTERING ABILITY OF MATERIALS FROM NATURAL AND SYNTHETIC FIBERS
Ключевые слова:filtering property, woven and non-woven material, low-temperature plasma, hydrophilicity, filtration rate, natural and synthetic fibers.
The research gives an overview of the range of textile materials for filters in the oil
industry. Modification of natural and synthetic textile materials and experiments connected
with increase in the filtering ability of textile materials were implemented and their
operational characteristics were investigated.
The experiments showed that metallized felt filters have an increased filtration rate in
comparison with the control sample and plasma treated samples.
It was established that use of ion-plasma deposition in combination with low-pressure
high-frequency capacitive plasma treatment allows to increase the operational characteristics
of woolen non-woven materials without deteriorating their strength properties, as well as to
increase the filter’s life at the average in 1.5 times.
It was shown that as a result of exposure to low-pressure high-frequency plasma the
structural changes occur associated with the redistribution of interfiber space in the entire
volume of nonwoven material, which lead to the production of filters with specified physicalmechanical and operational characteristics.
The use of the modified filters with increased filtering capacity at the oil refining
complex will increase the production efficiency and obtain a high-purity product.
