提高加氢法凡士林拉丝性能的研究

Discussion on factors that influenced the drawing character of vaseline

分析了影响加氢法凡士林拉丝性的各种因素,考察了不同性能、不同配比原料对拉丝性能的影响。通过控制原料复配体的脱壳性为未脱壳、25℃锥入度在130—180(0．1 mm)、100℃运动粘度在13—18 mm2／s,可控制和稳定凡士林的拉丝性。

This paper analysed factors that influenced the drawing character of vaseline, such as the influences of different materials and the proportion of raw materials. The mix - materials of vaseline is not exuviable, its cone penetration is 130 - 180（0.1 mm,25 ℃ ） ,kinematic viscosity is 13 - 18 mm^2/s（ 100 ℃ ） ,these mix - materials can produce super vaseline.
