炭前驱体形态对C/C复合材料导热系数的影响
INFLUNCE OF ARRANGING STRUCTURE OF CARBON PRECURSOR ON THERMAL CONDUCTIVITY OF C/C COMPOSITES
摘要
Abstract
Blinder was put into blue-coke powder and mixed uniformity, then modeled. The formed activated carbon based on blue-coke was produced after carbonization and activation. Carbonized behavior of the material was studied by TG-DTG during the pyrogenation process. The yield, compressive strength and iodine adsorption value of formed activated carbon which were prepared at different carbonization temperature. The pore structure and surface chemical properties of activated carbon which were prepared at 450 ℃ carbonization temperature were characterized by N2 adsorption and infrared spectrum respectively. It is found that the yield and compressive strength of products are reduced along with the rising of the carbonization tempera ture, while the iodine adsorption value is increased. There are a large number of hydroxyl, car bonyl, hydroxyacid and other active groups on the surface of products prepared under this experimental condition: 450 ℃ and 800 °C were selected to be carbonization and activation temperature and activated for 60 min using water vapor. And it is mesopores activated carbon.关键词
