摘要
分别以呋喃树脂、酚醛树脂、环氧树脂为黏结剂,以电锻煤和石墨为骨料,合成了施工温度为20±5℃的铝用冷捣糊。通过对合成冷捣糊的电阻率和抗压强度等常规性能检测可知,以树脂为黏结剂合成的冷捣糊具有低电阻率及高抗压强度等,达到国内冷捣糊的标准,与国外冷捣糊相比,合成冷捣糊的电阻率接近国外通常标准的下限,而抗压强度均高于国外厂家的标准。
Cold ramming paste of ramming temperature at 20±5 ℃ for aluminum electrolysis cell was synthesized with furan resin,phenol formaldehyde resin and epoxy resin as binder,respectively,with electro-calcined anthracite and graphite as aggregate.Conventional performance such as electrical conductivity and compression strength of synthesized cold ramming paste are investigated.The results show that the synthesized cold ramming pastes by resins have low electrical conductivity and high compression strength,which can reach our state standard.Furthermore,the electrical conductivity of synthesized cold ramming pastes is close to lower limit of foreign standard with compression strength higher than foreign standard.
