PLAs is known, the materials for the electrotechnical and electrochemical industries are prepared in such a way that the appropriate raw materials, with the possible admixture of powdered metal alloys, salts or silicates, are evenly distributed in the molten tar products, then crushed, kneaded, smoothed. It was prepared and finally pressed after a long process of planting. As a condition of obtaining a valuable final product, it was always important to thoroughly mix the raw materials and evenly distribute the various components in the finished factory. liquid tar products encounter great difficulties in practice, because after leaving the temperatures subjected to elevated temperatures, the tar substances immediately harden and local accumulation of various admixtures cannot be avoided, which significantly reduces the value of the final product. the use of heat to liquefy the tarry products as an emulsion, while the solubility of tar hydrocarbons in organic liquids such as benzol and the like and their volatile properties is used. The respective raw materials (graphite, etc.) are mixed with adding metal powders, etc. with asphalts, tars, etc. dissolved in liquid and volatile hydrocarbons; d., pressed into forms and dried by carbonaceous and electrochemical volatilization, characterized by hydrocarbons, then pressed into molds and using dissolved in liquids and broths. volatile hydrocarbons of asphalts as a means - In this procedure, it is avoided to thoroughly mix and bind local accumulations of various raw materials without using the above-mentioned materials. order from heat.
