溶液表面张力对反气泡稳定时间的影响
|
摘要
反气泡是产生于液体中并由一层气膜包裹液珠的特殊结构。影响反气泡稳定性的因素有温度、压强、电解质浓度、溶液黏度等,除此之外表面张力也是重要因素之一。通过实验发现,溶液表面张力的变化而变化的情况,当溶液的表面张力小于47 mN/m时,溶液开始产生反气泡;当溶液的表面张力在47～35 mN/m范围内时,反气泡稳定时间随表面张力减小而增大;当表面张力在35～34 mN/m范围内时,反气泡稳定时间随表面张力减小而减小;当表面张力小于34 mN/m时,反气泡稳定时间趋于稳定。
An anti-bubble is a special structure that is produced in liquid and is coated by a gas film. The lifetime of the anti-bubble is related to temperature, pressure, electrolyte concentration, viscosity and so on. Besides, surface tension of the solution is an important factor.According to the experiments, the lifetime of the anti-bubble changes along with the surface tension of the solution. When the surface tension of the solution σ is less than 47 mN/m, the anti-bubble could be generated in the solution. When the surface tension of the solution σ is in the range of 35 mN/m to 47 mN/m,the lifetime of the anti-bubble increases with the decreasing of the surface tension of the solution. When the surface tension of the solution σ is in the range of 34 mN/m to 35 mN/m, the lifetime of the anti-bubble decreases with the decreasing of the surface tension of the solution. When the surface tension of the solution σ is less than 34 mN/m, the lifetime of the anti-bubble is nearly stable.
