    • An apparatus and method is provided wherein the foam inhibiting effectiveness of defoaming and antifoaming additives on various types of foamable liquid mediums is measured. A single generally cylindrical foam cell having openings at both ends is provided wherein an interchangeable foam cell insert having varied geometry is longitudinally disposed within the foam cell. The foam cell insert is provided with a plurality of centralizer walls extending into the foam cell with an agitator member being carried by the centralizer walls. Foamable liquid medium is introduced into the foam cell and recirculated therethrough to form a dynamic fluid-flow system. As the liquid medium passes through both the foam cell and the foam cell insert, it comes into contact with the agitator member carried by the centralizer walls of the foam cell insert forming foam which accumulates in the foam cell. After a sufficient amount of foam is formed, a defoaming or antifoaming agent is introduced into the foam cell, and its effect on the level of foam present in the foam cell is measured. The interchangeable foam cell inserts are of varying lengths and carry varyingly configured agitator members, so that depending on whether a high or low foaming liquid medium is introduced, an appropriate foam cell insert may be chosen and inserted into the foam cell. The interchangeable foam cell inserts allow for a single foam cell to be used for measuring purposes thus decreasing the cost and potential down-time associated with such testing.
    • 提供了一种设备和方法,其中测量了消泡和消泡添加剂对各种可发泡液体介质的抑泡效果。 提供了在两端具有开口的单个大致圆柱形泡沫电池,其中具有不同几何形状的可互换泡沫电池插件纵向设置在泡沫电池内。 泡沫单元插入件设置有延伸到泡沫单元中的多个扶正器壁,搅拌器构件由中心壁承载。 将可发泡液体介质引入泡沫单元中并通过其循环以形成动态流体流动系统。 当液体介质通过泡沫单元和泡沫单元插入物时,它与由积聚在泡沫单元中的泡沫单元插入物形成泡沫体的中心壁承载的搅拌器构件接触。 在形成足够量的泡沫之后,将消泡剂或消泡剂引入泡沫电池中,并测量其对泡沫电池中存在的泡沫水平的影响。 可互换的泡沫单元插入件具有不同的长度并且携带不同配置的搅拌器构件,使得取决于是否引入高泡沫或低泡沫液体介质,可以选择适当的泡沫单元插入物并将其插入泡沫单元中。 可互换泡沫单元插入物允许将单个泡沫单元用于测量目的,从而降低与这种测试相关联的成本和潜在的停机时间。
