Polyacrylamide(PAM) in liquidum dissolvendum est. In application, PAM solutiones saepe redundant viscositatem et reductionem effecti flocculantis, quae effectum utilis effectum affectat. The Saiseco Environmental Protection Technology Chemical Factory, based on years of experience, has summarized the following reasons.

1. Storage time:

Cum tempore depositae solutionis PAM crescerit, plus et plus de illo degradat, resultat in lower viscosity and poorer flocculant effect. Usually, an anionic PAM solution can be stored for seven days, and an anionic PAM solution can be stored for 24 hours. Hoc est a causa hydrolysis grupae amidi et augentiae saturationis hydroxyli. Especially the influence of the presence of anionic groups is more obvious. The removal of NH3 from the amide group to form an imide group is what causes the increase in molecular chain rigidity.

2. Temperatura influentia:

For a 0.1% PAM solution, when the temperature reaches 80-90°C, the 1800 million molecular weight will degrade to around 500 million within 2-4 hours. As the temperature increases, the degradation becomes faster. Perfectus stabilis est in cubiculo temperatura 25ºC.

3. Mechanical effect influence:

Stirring can increase the dissolution speed of PAM dry pulvere. Alta intensitate turbationis velocitas catenas molecularum polyacrylamidi secebit. In 60 revolutionibus per minutam continere velocitatem. Non utilizat alta intensitate stirring equipment et alta velocitate convexionis equipment.

4. Light influence:

Lux elevabit temperaturam, ducit ad dissolutionem et degradationem polyacrylamidis. Direct exposure to ultraviolet light will cause rapid dissolution degradation. Under strong light exposure for 3-5 hours, the molecular weight of PAM will decrease by 30-50%.
