标准摘要
[中文适用范围]： 对于使用此类树脂作为浸渍材料的应用非常重要。 其原理是将丙酮/水混合物添加到树脂溶液中。 使由此产生的沉淀物沉降，并测量保留在树脂上方的悬浮液的电导。 然后根据测得的电导计算出电导率，以微西门子/厘米表示。 [外文原描述]： Important for applications in which such resins are used as impregnating materials. The principle is based on addition of an acetone/water mixture to a solution of the resin. The precipitate thus produced is allowed to settle, and the conductance of the suspension remaining above the resin is measured. The conductivity, expressed in microsiemens per centimetre, is then calculated from the measured conductance.
