羧甲基纤维素钠 (CMC),2200 规格。用于水系负极浆料的水溶性增稠剂和粘结剂。与 SBR 一起使用,作为标准水系粘结剂体系,取代 PVDF/NMP,并省去了电极涂布过程中的溶剂回收步骤。
| 属性 | 规格 |
|---|---|
| 干燥失重 | ≤ 10.0% |
| 粘度(1% 溶液,25 °C,60 rpm) | 1500 – 3000 mPa·s |
| pH 值(1% 溶液,25 °C) | 6.0 – 8.5 |
| 取代度 | 0.80 – 1.20 |
| 氯化钠 | ≤ 1.00% |
每批货物均随附特定批次的分析证书。以上数值为产品规格,非单批次检测结果。
2200 规格属于 1500 至 3000 mPa·s 的中等粘度范围,适用于大多数石墨负极浆料。更高粘度的规格在更高的混合成本下可提供更好的悬浮稳定性;低粘度规格适合更薄的涂层。CMC 通常以大约 1:1 至 1:2 的比例与 SBR 配合使用。
在剪切条件下缓慢分散于水中以避免结块,并在添加活性物质前使其充分水合。请密封干燥储存。
