摘要
用吊环测张力法研究了煤油在0～80 mT、0～60 min、30～60℃磁化条件下,其空气/油/水界面张力的变化规律。结果表明:在60 mT、30 min和30℃条件下,油/水界面张力值降低了19.2%,煤油接近磁饱和,继续单一增加磁场强度和延长磁化时间对油/水界面张力影响小。空气/油界面张力值受磁化时间和磁化强度的影响小,但随磁化温度30～60℃的升高,磁化煤油空气/油界面张力值降低得较未磁化煤油的慢,磁化煤油的油/水界面张力值先升高后降低逐渐与未磁化煤油的值接近。
The air/oiL/water interfacial tensions of magnectied kerosene test was carried out with the method of ring - pulling method by 0 ～ 80 mT magnetizing treated at 30 ～ 60 ℃ from 0 ～ 60 rain. It was found that 19.2% oil/water interfacial tensions decrease rate was achieved by 80 mT magnetizing treated at 30 ℃ and last 60 min, and kerosene was close to magnetic saturation that oil/water interfaeial tensions had little effeetion through increasing magnetic field intensity ＆ treating time alone. Air/oil interfaeial tensions of magneticed kerosene decreased slowly and it＇s oil/water interfacial tensions firstly decreased and then increased until close to untreated kerosene＇s under the treating temperature 30 60 ℃.
