Description
Изобретение относитс к способу графитации жестких углеродсодержащих веществ, например вискозы, полимеров.This invention relates to a method for the graphitization of rigid carbonaceous substances, for example, viscose, polymers.
Известен способ графитации жестких углеродсодержащих веществ путем приложени давлени 10000-25000 кг/см при температуре 1000-3000°С.There is a known method for graphitizing hard carbon-containing substances by applying a pressure of 10,000-25,000 kg / cm at a temperature of 1000-3000 ° C.
Однако такой способ требует уникального прессового оборудовани и позвол ет получать материал лищь в малых количествах.However, this method requires unique pressing equipment and allows obtaining material only in small quantities.
По предлагаемому способу труднографитируемые материалы в процессе нагрева подвергают деформации в диапазоне температур 400-700°С, оставл в дальнейшем ту же технологическую схему термообработки, что и при получении обычных графитовых материалов , при этом величина нагрузки 200 «:г/сж2.According to the proposed method, the hard-to-limiting materials in the heating process are subjected to deformation in the temperature range of 400-700 ° C, leaving the same technological scheme of heat treatment later as in the preparation of conventional graphite materials, while the load value is 200 ": g / szh2.
Материал, прошедщий карбонизацию по данному способу, может служить таким же исходным материалом дл изготовлени графитированных изделий, каким вл етс кокс.The carbonized material in this process can serve as the same starting material for the manufacture of graphite products, such as coke.
В качестве средства деформации используютс совместно или раздельно прессование, раст жение, экструзи , вальцевание.As a means of deformation, pressing, stretching, extrusion, rolling are used jointly or separately.
В результате применени данного способа получаемый материал имеет степень графитизации , характерную дл хорошо графитирующих веществ.As a result of using this method, the resulting material has a degree of graphitization characteristic of well-graphitizing substances.
Пример. Порошок полимера фенолформальдегидной смолы ФМ-2, порошок обезвоженный глюкозы, целлюлозное волокно были обработаны до 2300°С в инертной среде с выдержкой при конечной температуре 30 мин иExample. The polymer powder of phenol-formaldehyde resin FM-2, dehydrated glucose powder, cellulose fiber were treated up to 2300 ° C in an inert medium with an exposure at a final temperature of 30 minutes and

Иа полученных образцах измерено межслоевое рассто ние (методы рентгеноструктурного анализа) и диамагнитна восприимчивостьwith the application of deforming forces 200 "; g / cl 2 in the temperature range of 400-700 ° C. The obtained samples measured the interlayer distance (X-ray diffraction analysis methods) and the diamagnetic susceptibility
