聚丙烯酰胺中常用(yong)的(de)(de)(de)離(li)(li)子(zi)(zi)類型(xing)(xing)(xing)有三種：陽離(li)(li)子(zi)(zi)型(xing)(xing)(xing)、陰離(li)(li)子(zi)(zi)型(xing)(xing)(xing)和(he)非離(li)(li)子(zi)(zi)型(xing)(xing)(xing)。不同離(li)(li)子(zi)(zi)型(xing)(xing)(xing)的(de)(de)(de)聚(ju)丙烯(xi)(xi)酰(xian)(xian)胺(an)具有不同的(de)(de)(de)功用(yong)。由(you)于陰離(li)(li)子(zi)(zi)聚(ju)丙烯(xi)(xi)酰(xian)(xian)胺(an)和(he)陽離(li)(li)子(zi)(zi)聚(ju)丙烯(xi)(xi)酰(xian)(xian)胺(an)使用(yong)廣(guang)泛，許多客戶不知道怎(zen)么(me)區別它們(men)(men)，但這是能夠理解(jie)的(de)(de)(de)，由(you)于無(wu)論什(shen)么(me)離(li)(li)子(zi)(zi)型(xing)(xing)(xing)的(de)(de)(de)聚(ju)丙烯(xi)(xi)酰(xian)(xian)胺(an)在外(wai)觀(guan)上都是相同的(de)(de)(de)白色(se)顆(ke)粒，怎(zen)么(me)區別陰離(li)(li)子(zi)(zi)型(xing)(xing)(xing)和(he)陽離(li)(li)子(zi)(zi)型(xing)(xing)(xing)聚(ju)丙烯(xi)(xi)酰(xian)(xian)胺(an)？陽離(li)(li)子(zi)(zi)和(he)陰離(li)(li)子(zi)(zi)聚(ju)丙烯(xi)(xi)酰(xian)(xian)胺(an)的(de)(de)(de)區別是什(shen)么(me)？下面(mian)中北(bei)化工詳細為我們(men)(men)回答這個問題。

1.測驗pH值以判別：
將聚丙烯(xi)酰胺顆粒按一定(ding)(ding)份額溶(rong)解(jie)于水(shui)中，然后(hou)經(jing)過(guo)測定(ding)(ding)水(shui)溶(rong)液的pH值(zhi)(zhi)來(lai)判別。由于不(bu)同類型(xing)聚丙烯(xi)酰胺的pH值(zhi)(zhi)不(bu)同，所以用該辦法能(neng)夠鑒定(ding)(ding)聚丙烯(xi)酰胺的性能(neng)。可是，由于廠家的生產工藝不(bu)同，會出現一些偏差，也能(neng)夠經(jing)過(guo)測定(ding)(ding)生產工藝的pH值(zhi)(zhi)來(lai)判別。

2.從溶(rong)解時(shi)刻判別(bie)：
由于不(bu)(bu)同(tong)(tong)類(lei)型(xing)的(de)聚(ju)丙烯(xi)(xi)酰胺(an)(an)(an)在(zai)水中的(de)溶(rong)(rong)解(jie)(jie)(jie)時(shi)(shi)刻(ke)不(bu)(bu)同(tong)(tong)，能夠依據溶(rong)(rong)解(jie)(jie)(jie)時(shi)(shi)刻(ke)的(de)不(bu)(bu)同(tong)(tong)來判別。溶(rong)(rong)解(jie)(jie)(jie)時(shi)(shi)刻(ke)由短到長：陰離(li)子(zi)聚(ju)丙烯(xi)(xi)酰胺(an)(an)(an)<非離(li)子(zi)聚(ju)丙烯(xi)(xi)酰胺(an)(an)(an)<陽離(li)子(zi)聚(ju)丙烯(xi)(xi)酰胺(an)(an)(an)。陰離(li)子(zi)聚(ju)丙烯(xi)(xi)酰胺(an)(an)(an)的(de)溶(rong)(rong)解(jie)(jie)(jie)時(shi)(shi)刻(ke)約(yue)為30min，非離(li)子(zi)聚(ju)丙烯(xi)(xi)酰胺(an)(an)(an)的(de)溶(rong)(rong)解(jie)(jie)(jie)時(shi)(shi)刻(ke)約(yue)為40min，陽離(li)子(zi)聚(ju)丙烯(xi)(xi)酰胺(an)(an)(an)的(de)溶(rong)(rong)解(jie)(jie)(jie)時(shi)(shi)刻(ke)約(yue)為60min。因此(ci)，聚(ju)丙烯(xi)(xi)酰胺(an)(an)(an)的(de)類(lei)型(xing)能夠與溶(rong)(rong)解(jie)(jie)(jie)時(shi)(shi)刻(ke)大致區別。

3.混合添(tian)加法判別(bie)：
常(chang)常(chang)接(jie)觸聚(ju)丙(bing)(bing)烯(xi)酰(xian)胺的(de)(de)客戶可能(neng)知道陰離子(zi)聚(ju)丙(bing)(bing)烯(xi)酰(xian)胺和陽離子(zi)聚(ju)丙(bing)(bing)烯(xi)酰(xian)胺不能(neng)混合，由于(yu)(yu)混合參(can)加會(hui)(hui)有很強的(de)(de)反響(xiang)效果(guo)，由于(yu)(yu)正(zheng)負電荷接(jie)觸會(hui)(hui)形成棉(mian)絮狀物質，聚(ju)丙(bing)(bing)烯(xi)酰(xian)胺水(shui)溶液會(hui)(hui)變得污濁。該辦(ban)法(fa)適用(yong)于(yu)(yu)已知的(de)(de)聚(ju)丙(bing)(bing)烯(xi)酰(xian)胺離子(zi)型。由于(yu)(yu)這(zhe)種(zhong)辦(ban)法(fa)更準確，有條件(jian)的(de)(de)客戶能(neng)夠用(yong)這(zhe)種(zhong)辦(ban)法(fa)進行判別。

4.依(yi)據污水反(fan)響判別：
經過不同離(li)子類型的(de)(de)聚丙(bing)烯(xi)酰(xian)(xian)(xian)(xian)胺(an)(an)與污(wu)水(shui)的(de)(de)反響，能夠清楚地確認聚丙(bing)烯(xi)酰(xian)(xian)(xian)(xian)胺(an)(an)的(de)(de)類型。陰(yin)離(li)子聚丙(bing)烯(xi)酰(xian)(xian)(xian)(xian)胺(an)(an)一(yi)般(ban)適用于(yu)懸(xuan)浮(fu)物濃度高、帶(dai)正電(dian)荷和中性(xing)或堿性(xing)pH值(zhi)的(de)(de)廢水(shui)；陽離(li)子聚丙(bing)烯(xi)酰(xian)(xian)(xian)(xian)胺(an)(an)則適用于(yu)帶(dai)負電(dian)荷懸(xuan)浮(fu)物的(de)(de)污(wu)水(shui)。非(fei)離(li)子聚丙(bing)烯(xi)酰(xian)(xian)(xian)(xian)胺(an)(an)適用于(yu)污(wu)水(shui)pH值(zhi)為中性(xing)或酸性(xing)，無機和有機混合態懸(xuan)浮(fu)物的(de)(de)污(wu)水(shui)。
