A Study on the Spinning Process of Pitches from Petroleum Residues for Manufacturing Carbon Fiber
-
摘要: 本文研究了用于制造碳纖維的石油瀝青的紡絲工藝,包括紡絲溫度,壓力,速度及瀝青的結構和性質對紡絲性能的影響。探討了紡絲熔體的流變學特性。找出了用控制熔體粘度在10Pa·s泊左右來選擇紡絲最佳溫度的方法,及用增加紡絲壓力來提高可紡性的可能性。Abstract: In the paper, the spinning parameters of pitches from petroleum residues for manufacturing carbon fiber is investigated. The effects of the spinning temperature, pressure, speed and the pitch's structures and properties to spinning quality are discussed. The method of choosing the best spinning temperature with controlling melt viscosity at about 10 Pa·s, and the ability of enhancing the pitch's spinnability with raising spinning pressure are suggested.
