利江牌D941树脂产品说明书
产品简介：
利江牌D941是聚丙烯酸骨架的大孔型弱碱性阴离子交换树脂，含有-N（CH3）2。采用特殊工艺制成，具有交换容量大，体积变化小，机械强度高，化学稳定性好，抗污染，抗氧化性能优越，交换速度快等特点。
对应国外品牌：Amberlite IRA-68，Wofatit AP-9
产品应用：
主要用于柠檬酸、甜菊糖和维生素C的脱色，广泛用于食品行业。
注意事项：
1．产品的运输与保存：
产品湿态保存，温度在0度以上；长期不用，可密闭或加入5%以上的食盐水；运输时主要是防冻，树脂上面不可放置过重物品，以防树脂被压碎。
2．树脂的预处理：
一般要求可以采用碱-水-酸-水一个流程进行处理，严格要求需作三个循环，***处理成所要求的离子型态。
3．树脂的填装：
要考虑树脂的转型膨胀率大小，预留出足够的空间以防树脂溢出并能***有合适的液面高度；柱径比应在合理的范围，避免偏流；采用湿法装柱或反洗驱除树脂层内的气泡。
4．液体在进树脂柱之前，应经絮凝、过滤或沙滤等步骤，确保不含悬浮物，以免堵塞树脂孔道。
5．柱内长期不用树脂须洗净后掏出保存，或者在抗盐介质内可加盐水，并且需要保持页面不可脱水，同时还需要不定期的反洗树脂，目的是松动树脂，以防结块报废。
