Description

탄소성형체의 제조방법Manufacturing method of carbon molded body

본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음As this is a public information case, the full text was not included.

제1도는 질산처리전후의 원료의 IR측정결과를 나타내는 그래프.1 is a graph showing IR measurement results of raw materials before and after nitric acid treatment.

Claims (2)

핏치류를 원료로 하여 탄소성형체를 제조하는 방법에 있어서, 광학적 조직에 구애됨이 없이 연화점이 300℃이상인 핏치류를 250㎛이하의 입도로 분쇄한 후, 상기 입자를 200-350℃의 공기분위기에서 1-8시간 불융화처리를 시켜, 50-300㎏f/㎠의 압력으로 성형한 후 900℃이상의 온도에서 불활성분위기로 소결하는 것을 특징으로 하는 탄소성형체 제조방법.In the method for producing a carbon molded product using pitch as a raw material, the pitch is pulverized to a particle size of 250 μm or less after a softening point of 300 ° C. or more without regard to optical structure, and then the particles are air atmosphere at 200-350 ° C. 1-8 hours insoluble treatment at 50-300 kgf / ㎠ and molded at a pressure of 900 to more than 900 ℃ sintered in an inert atmosphere, characterized in that the carbon molded product manufacturing method. 핏치류를 원료로 하여 탄소성형체를 제조하는 방법에 있어서, 광학적 조직에 구애됨이 없이 연화점이 300℃이상인 핏치류를 250㎛이하의 입도로 분쇄한 후, 0.1-14Ν의 농도를 갖는 질산용액에 침적시킨 후 40-60℃의 온도로 가열, 30-180분간 교반하여 입자의 불융화 및 표면개질 후 이를 세척 및 건조시킨 후, 50-300㎏f/㎠의 압력으로 성형한 후, 900℃이상의 온도에서 불활성분위기로 소결하는 것을 특징으로 하는 탄소성형체 제조방법.In the method for producing a carbon molded product using pitch as a raw material, a pitch having a softening point of 300 ° C. or more is pulverized to a particle size of 250 μm or less without being bound to an optical structure, and then to a nitric acid solution having a concentration of 0.1-14 N. After immersion, it was heated to a temperature of 40-60 ° C., stirred for 30-180 minutes, insoluble in particles and surface modified, washed and dried, and then molded at a pressure of 50-300 kgf / cm 2 and then A method for producing a carbon molded article, which is sintered in an inert atmosphere at a temperature. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
