  聚丙烯酰胺生產廠家--簡單通過溶解時間來判斷陽離子聚丙烯酰胺!

  陽離子聚丙烯酰胺(CPAM)外觀為白色粉粒,是線型高分子化合物,由于它具有多種活潑的基團, 可與許多物質親和、吸附形成氫鍵。分子量從800萬到1200萬。離子度從20%到55%水溶解性好,能以任意比例溶解于水且不溶于有機溶劑。有效的PH值范圍為1到14,呈高聚合物電解質的特性,適用于帶陰電荷及富含有機物的廢水處理。

  如果同時有幾個陽離子聚丙烯酰胺小樣,小樣外包裝小袋子上又沒有標簽,我們是否有辦法分辨出陽離子聚丙烯酰胺的具體的離子度型號?承潔小編今天給大家講一個比較簡單實用的方法!通過看溶解時間就可以看出大概是哪個型號的:溶解時間最短的肯定為高陽離子度,溶解時間最長的一般為低陽離子度,故而中間的為中陽離子度,這個方法是個簡單通俗的方法,只是可以分析個大概,但是避免挨個試驗的弊端!

  陽離子聚丙烯酰胺(CPAM)在酸性或堿性介質中均呈現陽電性,這樣對污水中懸浮顆粒帶陰電荷的污水進行絮凝沉淀,澄清是極為有效的,如酒精廠廢水,啤酒廠廢水,味精廠廢水,制糖廠廢水,肉食品廠廢水,飲料廠廢水,紡織印染廠的廢水等。

  使用方法:

  1、聚丙烯酰胺使用時,配成0.01~0.03%濃度的水溶液,以使用中性不含鹽類雜物的水為宜。

  2、聚丙烯酰胺溶解時,將陽離子聚丙烯酰胺產品均勻撒入攪拌的水中,攪速控制在100~300rpm。適當加溫(< 60°C),可加速溶解。

  3、調整被處理液的PH值,使本系列產品充分發揮作用(通過試驗選擇最佳PH值和本系列產品的用量。)

  4、加入陽離子聚丙烯酰胺產品溶液時,應加速與被處理液的混合,出現絮凝物后,減慢攪速,以利絮凝物增長和加速沉降。
