摘　　要：通过将发泡液雾化喷嘴与气泡发生器相结合,提出了一种能同时发出两种不同泡径泡沫发泡机的设计思路,并以六方最密填充理论为依据,建立了两种直径泡沫堆积的模型,以此堆积模型分析发泡管中大小泡沫的理论直径比以及体积比,小泡与大泡直径比为0.1716,大泡与小泡的体积比为10.7。将此双泡径泡沫应用于泡沫砼时,使制得的泡沫混凝土在不影响强度的条件下其容重变得更轻,节省了原材料。并根据此理论模型设计了双泡径级配发泡管的技术参数。It proposes a design idea of a foam machine which can froth two bubble diameter of foam at the same time by connecting foam-liquid atomization nozzle with the foam generator theory, applies the hexagonal close packing theory for foundation, establishes two diameter＇s foam packing model, and then analyzes the theoretical diameter ratio and volume ratio of the double bubble, and the diameter ratio of the vesicles and bullae is 0.1716, and the volume ratio of the vesicles and buUae is 10.7. Applying the double bubble diameter foam in the foam concrete can make the foam concrete lighter under the condition of not changing the strength of foam concrete, and save raw materials. A ccording to this theoretical model, it designs the technical parameters of the double bubble diameter foam tube.
