METHOD OF CONDUCTING PANELS PRODUCTION, PRIMARY FURNACE FOR CONDUCTING PANELS PRODUCTION AND CONDUCTING FILLER BASED ON NATURAL ZEOLITE-CONTAINING EFFUSIVE SEDIMENTATION ASHY DEPOSITS Russian patent published in 2009 - IPC H01B1/04 H01B1/14 H05B3/10 

Abstract RU 2353012 C1

FIELD: electrical engineering.

SUBSTANCE: invention relates to electrical engineering industry and may be used for production of electric heating units and panels in house construction and industry. The production method of current-conducting panel where the above furnace and filler are used, includes mixing of the following components: graphite 7-9%, silicon carbide 3-5%, clay component 15-35, granulated current-conducting filler 4.5-10.5% and coal coke with particle of 0.2-1.5 mm size is the rest of the mixture. The current-conducting filler is represented with granules of 0.1-1.0 mm size and jointly grinded mixture, wt %: calcium carbonate - 1-5.6, graphite - 8-10.4, silicon carbide - 6-9.1, glass powder - 7-9.1, natural zeolite-containing effusive sedimentation ashy deposits - 63-78 and 8-12% water solution of liquid glass solution - 1.0-2.8, natural zeolite-containing effusive sedimentation ashy deposits - 63.0-77.0. Then raw items are moistened, folded by semi-dry pressing method and thermally treated in lightly oxidised gas medium at 970-1000°C. The primary furnace includes coal coke and grinded clay component as binging agent. In addition, the current-conducting material contains grinded graphite, silicon carbide and granulated current-conducting filler of 0.1-1.0 mm size. The current-conducting filler consists of the following components: calcium carbonate, graphite, silicon carbide, glass powder, 8-12% water solution of liquid glass and natural effusive sedimentation ashy deposits.

EFFECT: proposed group of inventions allows for widening choice of technical facilities and raw basis for production for environmentally friendly current-conducting penal-type items with wide application performance such as high operational temperature, specific power and absence of deformations during annealing and operation due low thermal shrinkage.
