Description
Изобретение относитс к технологи графитовы .х коНструкциолных материалов.The invention relates to technology graphite .Construction materials.
11звестен способ получени графита путем формовани и последуютцего нагрева смеси неирокаленного нефт ного пиролйзного кокса и каменноугольного нека.11, a method for producing graphite is known by molding and subsequent heating of a mixture of non-mineralized petroleum pyrolysis coke and coal coke.
Характерной особенностью известного способа вл етс недостаточно высокое качество графита.A characteristic feature of this method is the insufficient quality of graphite.
С целью повышени качества графита кокс предварительно смешивают с йодистым или П1,аБелево«ислым аммонием, вз тым в количестве , например, 0,3-2,0% от веса кокса.In order to improve the quality of graphite, coke is preliminarily mixed with iodide or P1, abelic acid ammonium, taken in an amount of, for example, 0.3-2.0% by weight of coke.
Пример. Массу из непрокаленного нефт ного пиролизного кокса с выходом летучих 3,5 % в количестве 60 вес. %, каменноугольно1 ,961,941.90Example. The mass of the uncalcined petroleum pyrolysis coke with the release of volatile 3.5% in the amount of 60 weight. % hard stone1,961,941.90

го пека с температурой разм гчени 150°С в количестве 40% йодистого или щавелевокислого аммон.и в количестве 2,0% от веса кокса подвергали совместному помолу и смешению в вибрационной мельнице.pitch with softening temperature of 150 ° C in the amount of 40% ammonium iodide or ammonium oxalate and in the amount of 2.0% of the weight of coke were subjected to joint grinding and mixing in a vibratory mill.
Сначала ведут размол и смешение кокса и йодистого или гцавелевокислого аммони 10 мин, а затем в эту смесь ввод т пек « размол продолжали еш.е 40 мин до получени порошка с размером частиц 90 мк. Полученный пресспорошок спрессовали в холодной пресс-форме при давлении 750 кгс/см. Отпрессова«ные заготовки (диаметром 250 мм) обожгли отграфитировали при температуре 24007г50°С.First, grinding and mixing of coke and ammonium iodide or ammonium hydroxide ammonium are carried out for 10 minutes, and then pitch grinding is introduced into this mixture for a further 40 minutes until a powder with a particle size of 90 microns is obtained. The resulting baking powder was pressed in a cold mold at a pressure of 750 kgf / cm. Otpressovye billets (with a diameter of 250 mm) were burned otgrafitirovali at a temperature of 24007g50 ° C.
Графитированный материал имеет следующие характеристики (средние значени ).The graphite material has the following characteristics (average values).
