产品优势Product advantages：
*实现了自动控制；
Automatic control;
*设计了新型柱体结构和物料布料装置，避免了壁流现象物料可定时正向、逆向流动吸附，解决了树脂装填不均匀及气泡造成的沟流和干锥现象；
The new column structure and material distribution device avoid the wall flow phenomenon, and the materials can flow and adsorb in the forward and reverse directions at regular intervals, and the channeling and dry cone phenomena caused by uneven resin loading and bubbles are solved;
*树脂顶部、底部吸附层移动较均匀，柱内树脂基本能达到吸附平衡，提高了树脂的利用率；
The adsorption layers at the top and bottom of the resin move evenly, and the resin in the column can basically reach adsorption balance, thus improving the utilization rate of the resin;
*可实现树脂柱单柱连续吸附操作和多柱连续吸附操作。可作为固定使用，也可作为模拟移动床使用。
Single column continuous adsorption operation and multi-column continuous adsorption operation can be realized. Resin adsorption column can be used as a fixed bed or as a simulated moving bed.
