脫色劑和聚丙烯酰胺的區別The difference between decolorizer and polyacrylamide

2022-03-07

聚丙烯酰胺絮凝劑雖然是具有一定的脫色功能，但畢竟不是廢水脫色產品，因此在脫色效果上并不是理想，比如用在高濃度、高色度的印染或印刷廢水當中，效果就不是那么明顯了，這時如果配套使用我們生產的雙氰胺甲醛樹脂...

Although polyacrylamide flocculant has a certain decolorization function, it is not a waste water decolorization product, so it is not ideal in terms of decolorization effect. For example, when used in high-con...

固色劑固色原理Color fixing agent fixing principle

2022-02-28

采用陽離子化合物作固色劑，對染料陰離子有較大的反應性，使染色物上的染料分子增大，親水基被封閉在織物上形成不溶性染料鹽沉淀。這樣，可防止染料因離子化而從織物上脫落及水解，從而提升色牢度。在纖維表面形成立...

The cationic compound is used as the fixing agent, which has a greater reactivity to the dye anion, so that the dye molecules on the dyed matter increase, and the hydrophilic group is blocked on the fabric to f...

自來水絮凝劑是什么?What is a tap water flocculant?

2022-02-25

由于目前我國水體污染嚴重，有些地方的原水甚至受到嚴重污染。如果仍用上述凈化工藝恐怕就很難達到市政自來水的標準。尤其是原水中的有機物和重金屬僅靠原先的工藝已經無法去除。而這些有機物、重金屬與水中的氯反應...

Due to the serious water pollution in our country, the raw water in some places is even seriously polluted. If the above purification process is still used, it may be difficult to reach the standard of municipa...
