作者通过对国内外拉制细钨丝用石墨乳中石墨颗粒性能的剖析和比较,采用新工艺获得了性能良好的石墨颗粒,再配以适当的乳胶研制成功了多模拉丝机拉制细钨丝用石墨乳,其润滑性能符合使用要求,与国产S-0~#石墨乳相比,具有石墨平均粒径小、用纯水稀释后不沉淀、无气泡和在钨丝表面上的附着性能好等优点,使拉丝钻石模孔利用率(超差前过丝长度)提高4～5倍以上,接近日本Acheson公司产石墨乳的质量水平,现已通过技术鉴定,並着手工业批量生产。
Through analyzing and comparing the properties of graphite particles in graphite milk made from fine tungsten wire both at home and abroad, the authors obtained the graphite particles with good performance by using the new technology and the successful preparation of the multi-die wire drawing machine with the appropriate latex. Compared with the domestic S-0 ~ # graphite milk, the graphite used in the invention has the advantages of small average particle size, no precipitation after precipitation with pure water, no bubbles and adhesion on the tungsten wire surface Good, and other advantages, so drawing diamond die hole utilization (before the over-the-wire length) increased 4 to 5 times more, close to Japan’s Acheson company’s quality of graphite milk, has passed the technical appraisal, and proceed with industrial mass production.
