href="http:///Products-33418212.html" target="_blank"><span style="color: rgb(0, 0, 0);">軟化水樹脂</span></a></strong></span>，可以根據(jù)其基體的種類分為：苯乙烯系樹脂和丙烯酸系樹脂。樹脂中化學(xué)活性基團的種類決定了樹脂的主要性質(zhì)和類別。</span></div><div><span style="font-size: 16px;"><br /></span></div><div><span style="font-size: 16px;"> 首先區(qū)分為陽離子樹脂和陰離子樹脂兩大類，它們可分別與溶液中的陽離子和陰離子進行離子交換。</span></div><div><span style="font-size: 16px;"><br /></span></div><div><span style="font-size: 16px;"> 陽離子樹脂又分為強酸性和弱酸性兩類，陰離子樹脂又分為強堿性和弱堿性兩類。</span></div><div><span style="font-size: 16px;"><br /></span></div><div><span style="font-size: 16px;"> </span><strong style="font-size: 16px;">軟化水樹脂</strong><span style="font-size: 16px;">更換方法：</span></div><div><span style="font-size: 16px;"><br /></span></div><div><span style="font-size: 16px;"> 1、拆下進出水管路，排污管，吸鹽管，取下控制閥頭;</span></div><div><span style="font-size: 16px;"><br /></span></div><div><span style="font-size: 16px;"> 2、抽出中心管，如罐體直徑大于500mm則不用取出中心管;</span></div><div><span style="font-size: 16px;"><br /></span></div><div><span style="font-size: 16px;"> 3、利用虹吸原理抽出樹脂;</span></div><div><span style="font-size: 16px;"><br /></span></div><div><span style="font-size: 16px;"> 4、安裝中心管，并在中心管上方用塑料布堵住，防止樹脂倒入中心管;</span></div><div><span style="font-size: 16px;"><br /></span></div><div><span style="font-size: 16px;"> 5、倒入樹脂，安裝控制閥頭;</span></div><div><span style="font-size: 16px;"><br /></span></div><div><span style="font-size: 16px;"> 6、把控制閥調(diào)到反沖洗位置(順流再生)小量給水，把樹脂罐氣排出;</span></div><div><span style="font-size: 16px;"><br /></span></div><div><span style="font-size: 16px;"> 7、看有無漏水現(xiàn)象，樹脂更換完成;</span></div><div><span style="font-size: 16px;"><br /></span></div><div><span style="font-size: 16px;"> </span><strong style="font-size: 16px;">軟化水樹脂</strong><span style="font-size: 16px;">被污染的判斷方法</span></div><div><span style="font-size: 16px;"><br /></span></div><div><span style="font-size: 16px;"> 1、被鐵污染的樹脂，從外觀上看，顏色明顯變深，變暗，呈暗紅褐色或黑色。樹脂強度變低，工作中產(chǎn)水量明顯減少，再生困難;</span></div><div><span style="font-size: 16px;"><br /></span></div><div><span style="font-size: 16px;"> 污染原因可能是水源水含鐵量高(>0.3毫克\升)或鋼制老式水處理設(shè)備防腐不良或干脆沒有;</span></div><div><span style="font-size: 16px;"><br /></span></div><div><span style="font-size: 16px;"> 2、防腐而引起的：</span></div><div><span style="font-size: 16px;"><br /></span></div><div><span style="font-size: 16px;"> 預(yù)防措施：對含鐵高的水源水，不能直接進入交換器，而必須行除鐵處理后，方可進行離子交換。</span></div><div><span style="font-size: 16px;"><br /></span></div><div><span style="font-size: 16px;"> 3、活性余氯的污染：</span></div><div><span style="font-size: 16px;"><br /></span></div><div><span style="font-size: 16px;"> 水源水余氯過高(>0.5毫克\升)會造成樹脂結(jié)構(gòu)的破壞，“中毒”后樹脂顏色明顯變淺，透明度增加，體積增大，強度急駐下降。樹脂破碎，但樹脂交換容量初期并不降低。</span></div><div><span style="font-size: 16px;"><br /></span></div><div><span style="font-size: 16px;"> 主要危害：被活性余氯污染嚴(yán)重的樹脂，將全部報廢。</span></div><div><span style="font-size: 16px;"><br /></span></div><div><span style="font-size: 16px;"> </span><strong style="font-size: 16px;">軟化水樹脂</strong><span style="font-size: 16px;">一般使用壽命為3-5年，如果經(jīng)過長期使用樹脂就會失效，出水就會不合格，影響鍋爐使用壽命。所以為了延長軟化水樹脂的使用期限，軟化水裝置會定期對罐內(nèi)樹脂進行反洗。</span></div> <div class="mxfazbizhu" id="news_sx"><li id="mxfazbizhu"
