Abstract:
Relevance The operating conditions of modern electronic products require a responsible approach to their protection from aggressive environmental influences. The use of imported materials in the production of special equipment is limited, so technologists are forced to look for effective ways to work with domestic materials, many of which were developed in the middle of the twentieth century. The use of Viksint U-1-18 sealant has not lost its relevance, it is widely and effectively used. Aim of research To offer an effective and ready-to-use method for pouring metal joints made of stainless steels, aluminum and titanium alloys, for sealing equipment operating in air at temperatures from minus 60 °C to 300 °C when exposed to vibrations — a method that does not require the use of advanced technological equipment. Research methods Review and analysis of normative and technical documentation and scientific literature, as well as generalization of experience in the use of organosilicon sealants by instrumentmaking and shipbuilding enterprises. Results A method has been developed for pouring the product with Viksint U-1-18 sealant. Documentation on the application of the method includes the following sections: — general provisions; — lists of basic and auxiliary materials, equipment, tools and fixtures; technological operations; — characteristics of the main materials (sealant «Viksint U-1-18», sealing paste U-1, catalyst No. 18, sublayer P 11, water-repellent liquid 136-41, active alumina); — safety precautions (indicating the toxic properties of the materials used and indicators of their fire and explosion hazard). Technological operations include: — preparation of products for pouring; — preparation of sealant «Viksint U-1-18» and paste No. 2; — filling products with sealant; — technical control. The proposed method is intended for small enterprises, workshops and laboratories for which the purchase of expensive technological equipment is unprofitable. The results of this work can be used as a reference tool by specialists of design bureaus and manufacturing enterprises, as well as labor protection units, including for the development of organization standards.
