【摘要】：為了更好地預(yù)測毛細被動閥的突破壓力,對液體的突破過程進行研究.利用液體界面能方程,分析毛細被動閥的工作原理.根據(jù)彎曲面所對應(yīng)圓心角的不同,將液體的突破過程劃分為3個階段,對親水被動閥在矩形微通道中的突破壓力進行三維理論分析.利用聚甲基丙烯酸甲酯(PMMA)為基材,制作了離心式被動閥芯片.通過可視化離心平臺得到了被動閥的突破頻率,與不同的三維突破模型進行對比分析.研究結(jié)果表明,該三維模型對被動閥突破壓力有著較準確的預(yù)測;模型所劃分的不同突破階段可以合理地描述被動閥的突破過程.
[Abstract]:In order to better predict the breakthrough pressure of the capillary passive valve, the breakthrough process of the liquid is studied. The working principle of the capillary passive valve is analyzed by using the liquid interface energy equation. The breakthrough process of liquid was divided into three stages, and the breakthrough pressure of hydrophilic passive valve in rectangular microchannel was analyzed theoretically. A centrifugal passive valve chip is made, and the breakthrough frequency of the passive valve is obtained through a visual centrifugal platform, which is compared with different three dimensional breakthrough models. The results show that, The three dimensional model can accurately predict the breakthrough pressure of the passive valve, and the breakthrough process of the passive valve can be reasonably described by the different breakthrough stages of the model.
