摘要
对白金板法测定橡胶胶乳表面张力的原理和优势进行了分析,考察了影响白金环法和白金板法测定橡胶胶乳表面张力的影响因素,建立了与白金环法数据具有可比性的白金板法。结果表明,在测定包括天然胶乳(NRL)和合成胶乳的6种橡胶胶乳表面张力时,建立的白金板法与白金环法测定结果相当;白金板法测定的表面张力重复性为0.31～0.57 mN/m。
The principle and advantages of measuring the surface tension of rubber latices by the plate method were analyzed.The factors affecting the determination of surface tension of rubber latices by the ring method and the plate method were investigated respectively.The results showed that the plate method for determining the surface tension of rubber latices was established,which was data comparable with the ring method.The results of the established plate method and the ring method were comparable when the surface tension of 6 rubber latices (natural and synthetic) were measured.The repeatability of the plate method was 0.31 to 0.57 mN/m.
