<p>硬水是含有一定數量的鈣、鎂、鐵、鋁和錳的碳酸鹽，還有重碳酸鹽、氯化物、硫酸鹽以及硝酸鹽雜質的水。其中鈣、鎂鹽類物質在自然界分布廣泛，是硬水的主要組成成分。通常工業用水，陶瓷，洗滌，印染等工業上使用的軟水，東福工業<a href='http://www.top50usmodels.com' target='_blank' title='六偏磷酸鈉' ><strong>六偏磷酸鈉</strong></a>是運用比較廣泛的磷酸鹽軟水劑，</p><p>軟水是相對硬水而言，一般將去除了鈣、鎂鹽類物質的水稱為軟水。</p><p>水的軟硬程度可用度數來表示，這個度數稱為硬度，它表示水中鈣、鎂離子含量的多少。水的硬度分為暫時硬度和硬度，兩者的和為總硬度。</p><p>腐蝕原因：</p><p>厭氧菌：</p><p>1、具有強腐蝕性</p><p>2、可生存在氧氣缺乏的地方。</p><p>3、可產生強烈的破壞性：尤其在營養源充足的地方，比如硫，其產物具有強腐蝕性。</p><p>4、可導致局部腐蝕，穿孔，極難處理。</p><p>鐵細菌：</p><p>廣泛存在于水源中，能將Fe轉化為FeO。</p><p>硝化菌</p><p>能將NH3轉化為NO3－，降低pH值，使水具有腐蝕性。</p><p>因此，要使聚磷酸鹽發揮較好的緩蝕作用，冷卻水中要求有一定的兩價金屬離子，例如鈣、鐵或鋅離子等，在鈣離子含量很少的軟水中是不適宜用聚磷酸鹽作緩蝕劑的。水中除鈣含量對聚磷酸鹽的緩蝕效果有很大影響外，溶解氧的含量也影響防腐效果，這是因為如果水中不含溶解氧，水中的聚合磷酸鹽要與鐵形成可溶性的絡合物而促進腐蝕。</p><p> 然而東福<a href='http://www.top50usmodels.com' target='_blank' title='六偏磷酸鈉' ><strong>六偏磷酸鈉</strong></a>是聚磷酸鹽作為水中溶解的金屬離子形成絡合物，沒積在金屬表面，形成保護膜而減緩腐蝕。</p><p>暫時硬度是由重碳酸鹽(如碳酸氫鈣、氫氧化鎂)所造成的硬度，它在水煮沸后形成沉淀而使硬水軟化。因能采取加熱方法清除可溶性雜質，可變為軟水。</p><p>硬度是由溶于水中的鈣、鎂等氧化物、氯化物、硝酸鹽或硫酸鹽等引起，它們在煮沸后有些可以去除，有些不能除掉。特別是硫酸鹽、氯化物根本不能去除，但如果采取加入軟水劑等化學原料，硬水也是可以軟化的。如：河南東福環?？萍脊I<a href='http://www.top50usmodels.com' target='_blank' title='六偏磷酸鈉' ><strong>六偏磷酸鈉</strong></a>就能起到絡合硬水中的鈣，鎂等金屬離子。</p><p>水的硬度的表示方法有多種，通常以100萬份水中鈣、鎂含量換算成碳酸鈣的份數來表示，即PPM值。還有用德制硬度表示的，其換算關系為：1德國度=17.8PPM</p><p>　　硬水與軟水是按其度數區分，通常分以下5種：</p><p>　　極軟水 15PPM以下</p><p>　　軟水 15~50PPM</p><p>　　中硬 50~100PPM</p><p>　　硬水 100~200PPM</p><p>　　極硬水 200PPM以上</p><p>分散劑的定義是分散劑能降低分散體系中固體或液體粒子聚集的物質。在制備乳油和可濕性粉劑時加入分散劑和懸浮劑易于形成分散液和懸浮液，并且保持分散體系的相對穩定的功能。</p><p><br/></p> </div> <ul
