離子交換樹脂的貯存

Lewatit 離(li)子(zi)交換樹脂的(de)貯存(cun)

1、要(yao)保持樹脂(zhi)的水(shui)(shui)(shui)(shui)分。Lewatit樹脂(zhi)出(chu)廠時，其含(han)水(shui)(shui)(shui)(shui)率是飽(bao)和(he)(he)的，在貯存過程中必(bi)須(xu)防(fang)止水(shui)(shui)(shui)(shui)分的消失。建議(yi)將離(li)子交(jiao)換(huan)樹脂(zhi)儲存于(yu)干(gan)燥(zao)、沒有陽光(guang)直射(she)的室內.如發現(xian)樹脂(zhi)變干(gan)時，切忌(ji)將樹脂(zhi)直接(jie)置于(yu)水(shui)(shui)(shui)(shui)中浸(jin)泡(pao)，而應(ying)該(gai)將它置于(yu)飽(bao)和(he)(he)食1鹽水(shui)(shui)(shui)(shui)中浸(jin)泡(pao)，使樹脂(zhi)緩慢膨(peng)脹，然后(hou)再逐漸稀(xi)釋食1鹽水(shui)(shui)(shui)(shui)溶液。

2、應將樹(shu)脂(zhi)(zhi)(zhi)貯(zhu)存在產品(pin)資料(liao)中推薦的合適溫度下(xia)。若(ruo)貯(zhu)存的溫度過高，容易引起樹(shu)脂(zhi)(zhi)(zhi)交換(huan)基(ji)團的分解(jie)和(he)微(wei)生物污染。若(ruo)貯(zhu)存在水的冰點之(zhi)下(xia)，會使樹(shu)脂(zhi)(zhi)(zhi)內的水分。如果樹(shu)脂(zhi)(zhi)(zhi)，不能用(yong)(yong)機械方法處理，將其置于環境(jing)溫度中逐步解(jie)凍(dong)。在處理或使用(yong)(yong)前，應當使樹(shu)脂(zhi)(zhi)(zhi)完全解(jie)凍(dong)。不能試圖(tu)去加(jia)速解(jie)凍(dong)過程。

3、防(fang)止樹脂受(shou)到污染。樹脂貯存時要避免和(he)鐵(tie)容器(qi)、氧化(hua)劑和(he)油類物質直接接觸，以(yi)免樹脂被污染或被氧化(hua)降解。

4、貯存期不要超(chao)過(guo)產品資料中的推薦(jian)值。
