一、樹脂對使用的溫度有何要求?

各種樹(shu)(shu)(shu)(shu)(shu)脂(zhi)(zhi)(zhi)(zhi)均具一(yi)定(ding)(ding)的(de)(de)耐熱性能(neng)，在使用(yong)中對溫度(du)要求都(dou)有一(yi)定(ding)(ding)的(de)(de)界限(xian)，過高或(huo)過低(di)都(dou)會嚴重影響樹(shu)(shu)(shu)(shu)(shu)脂(zhi)(zhi)(zhi)(zhi)的(de)(de)機械強(qiang)(qiang)度(du)和交換容量(liang)。溫度(du)過低(di)如小于(yu)或(huo)等于(yu)0℃時(shi)，樹(shu)(shu)(shu)(shu)(shu)脂(zhi)(zhi)(zhi)(zhi)易凍結，使機械強(qiang)(qiang)度(du)降低(di)，顆(ke)粒破碎，從而影響樹(shu)(shu)(shu)(shu)(shu)脂(zhi)(zhi)(zhi)(zhi)的(de)(de)使用(yong)壽命、降低(di)交換容量(liang);溫度(du)過高，會引起樹(shu)(shu)(shu)(shu)(shu)脂(zhi)(zhi)(zhi)(zhi)熱分解，也(ye)影響樹(shu)(shu)(shu)(shu)(shu)脂(zhi)(zhi)(zhi)(zhi)的(de)(de)交換容量(liang)和使用(yong)壽命。各種樹(shu)(shu)(shu)(shu)(shu)脂(zhi)(zhi)(zhi)(zhi)的(de)(de)耐熱性能(neng)應(ying)由鑒定(ding)(ding)試驗來確定(ding)(ding)。但一(yi)般來說，陽樹(shu)(shu)(shu)(shu)(shu)脂(zhi)(zhi)(zhi)(zhi)比(bi)陰樹(shu)(shu)(shu)(shu)(shu)脂(zhi)(zhi)(zhi)(zhi)的(de)(de)耐熱性能(neng)好(hao)。鹽型(xing)樹(shu)(shu)(shu)(shu)(shu)脂(zhi)(zhi)(zhi)(zhi)比(bi)H型(xing)或(huo)OH型(xing)好(hao)，而鹽型(xing)又以Na型(xing)樹(shu)(shu)(shu)(shu)(shu)脂(zhi)(zhi)(zhi)(zhi)耐熱性能(neng)最(zui)好(hao)。一(yi)般的(de)(de)陽樹(shu)(shu)(shu)(shu)(shu)脂(zhi)(zhi)(zhi)(zhi)可耐100~110℃，陰樹(shu)(shu)(shu)(shu)(shu)脂(zhi)(zhi)(zhi)(zhi)可耐50~60℃(強(qiang)(qiang)堿性)。而弱(ruo)堿陰樹(shu)(shu)(shu)(shu)(shu)脂(zhi)(zhi)(zhi)(zhi)的(de)(de)耐熱性能(neng)要比(bi)強(qiang)(qiang)堿性的(de)(de)好(hao)，一(yi)般可耐80~90℃。因此，樹(shu)(shu)(shu)(shu)(shu)脂(zhi)(zhi)(zhi)(zhi)在使用(yong)時(shi)，對于(yu)水溫要有嚴格(ge)的(de)(de)控(kong)制。

二、使用樹脂注意事項

1、離子交換樹(shu)(shu)脂含(han)有一(yi)定水(shui)(shui)份，不宜(yi)露天存(cun)放(fang)，儲運(yun)過程中應(ying)保持濕潤，以免(mian)風干脫水(shui)(shui)，使樹(shu)(shu)脂破(po)(po)碎，如貯(zhu)存(cun)過程中樹(shu)(shu)脂脫水(shui)(shui)了(le)，應(ying)先(xian)用濃(nong)食鹽水(shui)(shui)（10%）浸(jin)泡(pao)，再逐漸稀釋，不得(de)直接放(fang)入水(shui)(shui)中，以免(mian)樹(shu)(shu)脂急(ji)劇膨脹而破(po)(po)碎。

2、冬季儲運使用中(zhong)，應(ying)保持(chi)在5-40℃的溫(wen)度環(huan)境中(zhong)，避免過冷或過熱，影響質(zhi)量，若冬季沒有保溫(wen)設(she)備時，可將樹脂貯存在食鹽水中(zhong)，食鹽水濃(nong)度可根據(ju)氣溫(wen)而定。
