1.研究了大豆磷脂HLB值与乳化温度、大豆磷脂中PC含量的关系,以及PC含量对乳化效果的影响:随PC含量、乳化温度的增加,大豆磷脂的HLB值增加,而大豆磷脂乳化效果变差,分层时间缩短。
2.研究了磷脂作为柴油—工业乙醇混合燃料乳化剂的最佳乳化条件:在常温常压下,柴油:工业乙醇(V:V)=80:20时,搅拌速度为13000转/分钟,搅拌时间1分钟,浓缩大豆磷脂添加量为3%。
3.比较了大豆磷脂与其他乳化剂复配时对柴油—工业乙醇混合燃料的乳化效果:试验证明单独使用磷脂的乳化效果与合成乳化剂仍有一定差距,但磷脂与合成的乳化剂复配使用的效果比单独使用任意一种乳化剂的效果好,能够明显增强乳化液的稳定性。在乳化剂配比为司班85:吐温80:浓缩磷脂=80:10:10时,混合燃料的稳定时间可达72分钟。

1. has studied the soybean phosphatide HLB value and the emulsified
temperature, in the soybean phosphatide the PC content relations, as
well as the PC content to emulsifies the effect the influence: Along
with the PC content, the emulsified temperature adding, the soybean
phosphatide HLB value adds, but the soybean phosphatide emulsification
effect changes the difference, the lamination time reduces. 2. studied
the phosphatide to take the diesel oil □industry ethyl alcohol
blended fuel emulsifier the best emulsified condition: Under normal
temperature atmospheric pressure, diesel oil: When industry ethyl
alcohol (V:V) =80:20, the mixing speed is 13,000 revolution
of/minutes, stirs the time 1 minute, the concentration soybean
phosphatide recruitment is 3%. 3. has compared the soybean phosphatide
and other emulsifiers duplicate 配时 to the diesel oil □industry
ethyl alcohol blended fuel emulsified effect: The experiment proved
the independent employment phosphatide the emulsified effect and the
synthesis emulsifier still had the certain disparity, but
phospho-lipin and the synthesis emulsifier duplicate matched the use
the effect to be wilfully better than the independent employment one
kind of emulsifier effect, could obviously strengthen the emulsion the
stability. In the emulsifier allocated proportion is Si Ban 85: Twain
80: When concentration phosphatide =80:10:10, the blended fuel
settling time may amount to 72 minutes.

1. has studied the soybean phosphatide HLB value and the emulsified temperature, in the soybean phosphatide the PC content relations, as well as the PC content to emulsifies the effect the influence: Along with the PC content, the emulsified temperature increase, the soybean phosphatide HLB value increases, but soybean phosphatide emulsification effect variations, lamination time reduction.
2. studied the phosphatide to take the diesel oil - industry ethyl alcohol blended fuel emulsifier the best emulsified condition: Under normal temperature atmospheric pressure, diesel oil:Industry ethyl alcohol (V:V) =80:20 o'clock, the mixing speed is 13000 revolution of/minutes, the agitation time 1 minute, the concentration soybean phosphatide recruitment is 3%.
3. has compared the soybean phosphatide and other emulsifier duplicate timing to the diesel oil - industry ethyl alcohol blended fuel emulsified effect: The experiment proved the independent employment phosphatide the emulsified effect and the synthesis emulsifier still had certain disparity, but phospho-lipin and the synthesis emulsifier duplicate matched the use the effect to be better than the independent employment random one emulsifier effect, could strengthen the emulsion obviously the stability. In the emulsifier allocated proportion is the department class 85:Twain 80:Concentration phosphatide =80:10:10 o'clock, the blended fuel settling time may amount to 72 minutes.
