不透性石墨具有优良的耐腐蚀性能,是很好的非金属耐腐蚀材料。用于防腐蚀设备的石墨系人造石墨。在制造人造石墨高温焙烧过程中挥发分溢出,使石墨材料疏松,形成多孔(一般孔率在20～30％),对气体或液体都有渗透性。为了克服这个缺点,采用浸渍的办法,使石墨孔隙填塞,制得不透性石墨材料。我们用酚醛树脂浸渍后的不透性石墨板材,用酚醛胶泥做粘结剂,衬在已做好隔离层(衬胶或衬玻璃钢)的金属设备、混凝土设备或地坪上。这种做法已成功地应 Impermeable graphite has excellent corrosion resistance and is a good non-metallic corrosion resistant material. Graphite artificial graphite for anti-corrosion equipment. In the manufacture of artificial graphite high-temperature roasting process volatiles overflow, the graphite material loose, forming a porous (usually porosity in 20 ~ 30%), both gas or liquid permeability. In order to overcome this shortcoming, impregnation was used to fill the pores of the graphite to produce an impermeable graphite material. We impregnated the impervious graphite sheet with phenolic resin and used phenolic cement as the binder to line up the metal equipment, concrete equipment or floor that has been used for the isolation layer (lined with rubber or lining FRP). This practice has been successfully applied
