本研究成功地制取了膨胀石墨(照片1),其最大膨胀倍率可达200倍。制取工艺简捷,并可稳定地获得不同膨胀倍率的石墨材料,以满足不同用途的需要。一、试验设计石墨的膨胀率是多因素的函数。本研究的总体试验设计安排为:1.石墨原料如表1。试验选用的无机含氧酸为H_2SO_4、HNO_3、HClO_4等,均为工业纯。2.采用正交表L_(16)(2~(15))对影响石墨膨胀率的诸因素进行筛选,以确定影响的主
The study successfully prepared expanded graphite (Photo 1), the maximum expansion ratio up to 200 times. Preparation process is simple, and stable access to different expansion ratio of graphite materials to meet the needs of different uses. First, experimental design Graphite expansion rate is a multi-factor function. The overall experimental design of this study is arranged as follows: 1. The graphite raw materials are shown in Table 1. The inorganic oxygen acids selected for the experiment are H 2 SO 4, HNO 3, HClO 4, etc., all of which are industrial pure. 2. Using orthogonal table L_ (16) (2 ~ (15)) to screen the factors that affect the rate of graphite expansion to determine the impact of the main
