吸油树脂的缓释性能研究

Research on the function controlled-release for oil absorption resins

以聚甲基丙烯酸丁酯(PBMA)和聚甲基丙烯酸十二酯(PLMA)两种吸油树脂对航空煤油和二甲苯的缓释过程为对象,研究了他们对这两种油品的吸油率(Q)、缓释保油率(Ka)以及缓释动力学过程。研究表明:PBMA和PLMA对航空煤油和二甲苯的Q都随时间延长而增大;PBMA和PLMA对航空煤油的缓释性能均较好,Ka在98%以上;对航空煤油和二甲苯,PBMA的Ka均大于PLMA;PBMA对航空煤油的缓释速率大于对二甲苯,PLMA对二甲苯的缓释速率则大于航空煤油。

The oil absorption performances of PBMA and PLMA for aviation kerosene and dimethylbenzene were studied. and Q,Ka and the controlled-release process were also analyzed. The results show that the oil-absorption of PBMA and PLMA increase with the time,PBMAAND PLMA have excellent controlled-release ability,and Ka of both are greater than 98%,For aviation kerosene and dimethylbenzene, PBMA has higher Ka than PLMA,at the same time,concerning controlled-release rate for aviation kerosent, PBMA performs better comparing with dimethylbenzene,while PLMA better for dimethylbenzene release.
