Abstract:
The invention relates to the field of cleaning the environment, and more particularly to a sorbent material for collecting petroleum and petroleum products, and to a method of producing the same. The method includes saturating a basalt fiber canvas with a hydrophobizing liquid and subsequently drying the same, wherein the basalt fibers of the canvas have a diameter of 0.2-2 microns and a density not exceeding 20-25 kg/m3; prior to saturation, the canvas is first fluffed using compressed air until a density of 12-15 kg/m3 is reached; the saturation using a hydrophobizing liquid is performed by introducing the hydrophobizing liquid into the pre-fluffed basalt fibers of the canvas in the form of aerosol particles via compressed air; and the subsequent drying of the saturated canvas is performed using compressed air, preferably at a temperature of 65° C.-75° C. The technical effect of invention is a simplified method with a broader field of application. The material manufactured in accordance with this method is characterized in that the volume of hydrophobizing additive is selected in order to achieve a density of the finished material which is in the range of 10-70 kg/m3, or in the range of 10-15 kg/m3, in the range of 30-70 kg/m3. This improves the sorbent characteristics of the material.
