Sodium carboxymethyl cellulose can react with many substances in use, and many phenomena can occur during the reaction process, and the surface tension of CMC-Na is one of them. However, many users are not clear about the manifestations of this phenomenon, so Henan Shengjiu Industry Co., Ltd. will take a look together.
1. Sodium carboxymethyl cellulose is generally low in surface tension, and is suitable for applications that require high surface activity and high dispersing power.
2. The typical surface tension of organic materials ranges from 30 to 40 dyn/cm, and the surface tension of water at room temperature is about 72 dyn/cm.
3. The surface tension of this product is relatively low, and the surface tension is basically independent of viscosity (when the viscosity scale is 20 to 100000 mm2/s35 ℃, the surface tension is 21 dyn/cm).
In summary, the surface tension of sodium carboxymethyl cellulose is presented according to the environment used, and the scale of its appearance may vary depending on the substance and environment used. Therefore, in use, relevant judgments can be made on its surface tension according to the requirements of use.
