摘要(Abstract):
以煤为原料,经溶剂抽提、过滤、脱溶、加氢聚合和真空蒸发后得到软化点大于230℃的可纺煤沥青(各向同性沥青)。经纺丝测定,该沥青可用于制备通用级碳纤维。
The pitch(isotropic pitch) with softening point over 230 ℃ obtained through extraction,filtration,desolvent,hydrotreatment,polyreaction and vacuum evaporation from coal can be used to produce universal carbon fiber.
