发动机进气系统高通量富氧膜的研制
Preparation of a high flux oxygen-rich membrane for engine' s air-intake systems
摘要
Abstract
The vinyl silicone rubber with low molecular weight was modified by crosslinking modification to prepare an ox-ygen-enrich membrane with high flow performance.With the single factor test and the Design-expert, the influences of the facters of raw material ratio, reaction time, curing temperature and curing time on the prepared membrane were investigated, and the best preparation conditions were determined as follows:the ratio of raw materials is 4.3, the reaction time is 2.15h, the curing temperature is 86.25℃and the curing time is 1.75h.A membrane with the oxygen concentration of 28.68%and the air permeation of 4696.33 barrer was made under the conditions, which could be applied to the oxygen-rich air-intake system of engines.The surface and cross-section of the membrane were observed by scanning electron microscope, respectively.关键词
