Influence of average carbon number on poly-olefin lube oil's viscosity index and condensation point

烯烃平均碳数对聚-α烯烃合成油粘度指数和凝点的影响

Total base number of the product may be up to 350~ 580mg KOH/ g, and its kinematic viscosity at 100 ℃ is 50~ 150mm 2/ s.

产品总碱值350～580mg KOH·g-1，而其100℃运动粘度可稳定在150mm2/s以下的较低范围内。

Waste PET and its products, especially the second waste from reusing process, unfit to reuse directly because lower instrinsic viscosity number.

废PET及其制品特别是直接回收加工产生的二次废料，因特性粘度过低已不宜直接再利用。

The kappa number of slash pine kraft pulp ( kappa no. 28. 2, viscosity 1024ml/ g) can be decreased by 45. 0% and 32. 3% respectively by oxygen and hydrogen peroxide delignification.

湿地松KP浆（卡伯值28.2，粘度1024ml/g）经氧和过氧化氢脱木素，卡伯值分别降低45%和32.3%。

The results showed that there is a boundary for applying low base number ASP flooding, since low alkali concentration could make ASP solution have high viscosity and high interfacial tension ( IFT).

结果表明，低碱ASP驱在提高体系粘度的同时也造成界面张力升高，因而有其适用界限。
