Use of sylvinite dedicated to Verkhnekamskoe field of potash and magnesium to increase quality and ionization of air environment
Abstract
Urbanization of territories and growth of man-made air pollution require creating and widely implementing means, methods and materials to increase air quality of indoor premises through ionization. Increase of air quality of indoor premises is on the front burner which is caused by following reasons of natural air deionization: aerosol and gas pollution and air cleaning from its pollution. Wherein, use of conventional methods of electrostatic generation of air ions is restricted by its side effects. This paper reviews new prospecting methods to create qualitative and treatment air environment inside premises through its air ionization by interaction of air and natural sylvinite, containing silvite (potassium chloride). The paper presents generalized experimental data including air ionization of premises for treatment and health-recovering purposes that represent sylvinite speleoclimatic chambers with surfaces of different design made of either sawn sylvinite blocks of natural sylvinite or pressed salt tile with high concentration of potassium chloride etc. Air ionization occurs primarily due to beta radiation of natural radioactive isotope potassium-40. Concentration of air ions of positive and negative polarity and different mobility (light, moderate and heavy air ions) are studied. Spectrum distribution of air ions of light mobility group of negative polarity are analyzed in details. In the range of mobility more than 2 cm2В–1sec–1 unipolarity coefficient is always less than 1. In the range of 1–2 cm2В–1sec–1 unipolarity coefficient is larger than 1. Obtained results prove high efficiency of application of sylvinite construction materials to create high-quality, treatment or health-recovering air environment, allow to select special construction and decoration materials based on sylvinite depending on required parameters of air ion composition it order to create high-quality air in the premises.
