STUDYING THE EFFECT OF ORGANOSILICON COMPOUND ON THE PROPERTIES OF GLASS

Abstract

The paper studies the effect of organosilicon compounds on the properties of silicate glass. Solid films can be divided into two large groups, one of which is films used in electronics, radio engineering and high-frequency devices, the second group is films that are applied to the surface of any product. The importance of thin transparent films is that they change the chemical, electrical or optical properties of the surface of the material from which the object is made. Due to its hydrophilic properties (wetting angle θ = 0^O), a layer of water is constantly present on the clean surface of the glass, which is difficult to remove even at temperatures above 200°C. To impart hydrophobic properties to glass, it is treated with organosilicon compounds. Good adhesion of the siloxane layer, resistant to high temperatures (up to 300°C), not washed off by water, alcohol and organic solvents, is due to the chemical treatment of siloxanes. With the development of technology, glass is becoming increasingly important as a building material, so the requirements for its mechanical strength are increasing. The mechanical strength of ordinary silicate glass was compared with the mechanical strength of hydrophobized glass and it was found that hydrophobized glass increases the mechanical strength of glass by 1.5 times.

The main optical characteristics of a thin film include the refractive index, dispersion, and permeability in a given spectral range. After applying the layer, the glass reflection decreases, the light output increases, and the amount of reflected light decreases due to the interference of rays reflected from the film-air and film-glass boundaries.

Dimethyl sioxane reduces light reflection, resulting in increased light emission. Glasses with a siloxane coating act as clarifying glasses, and light transmission increases from 81% to 89%.
