| description | The present invention relates to a method for preparing graphite oxide for a heating unit, which comprises the steps of: firing and pulverizing conventional graphite ore to prepare high-purity graphite powder; introducing sulfuric acid, nitric acid and potassium nitrate powder into a reactor to obtain a mixed acid and introducing the high-purity graphite powder to the reactor, followed by mixing; aging the mixture agitated in the reactor; heating the aged mixture to carry out reaction and introducing distilled water to carry out cooling; filtering and dehydrating the cooled mixture to obtain graphite oxide paste; and neutralizing the graphite oxide paste to pH 7-8.
본 발명의 일 실시예에 따른 발열체용 산화흑연의 제조방법은, 일반흑연광물을 소성 및 분쇄하여 고순도의 흑연분말을 준비하는 과정; 반응기에 황산, 질산 및 질산칼륨 분말을 투입하여 혼합산을 제조하고 상기 고순도의 흑연분말을 상기 반응기에 투입하여 믹싱하는 과정; 상기 반응기에서 교반한 혼합물을 숙성시키는 과정: 상기 숙성된 혼합물을 가열하여 반응시킨 후 증류수를 투입하여 냉각시키는 과정; 상기 냉각된 혼합물을 필터링하고 탈수하여 산화흑연 페이스트를 제조하는 과정; 및 상기 제조된 산화흑연 페이스트를 pH 7~8로 중화시키는 과정을 포함한다. |
