Title: METHOD FOR THE HYDROPHOBIZATION OF A SUBSTRATE
Abstract:
The present invention relates to a method for the hydrophobization of the surface of substrates and can be used for the preparation of a substrate in gas-carrying systems for extraction and storage of natural gas samples, for example of a vessel for the storage of gas and a supply pipe, in systems for quality control of products in the oil and gas industry, in chemical analysis laboratories, in the manufacture of analytical instruments and chromatographs, in commercial metering units, in systems which measure the quantity and quality characteristics of gas and liquefied hydrocarbon gases in main gas pipelines. The method for hydrophobization of a substrate includes stages involving the preparation of at least one substrate surface and the deposition of amorphous silicon on at least one substrate surface. The substrate surface preparation stage includes the cleaning of the surface using an organic solvent at a temperature of 25°С to 35°С, the treatment of the surface with a solution of mineral acid at a temperature of 20°С to 30°С and the drying of the substrate surface in an inert gas atmosphere.
