Product Application
polyacrylamide application
water treatment
In water treatment, anionic polyacrylamide is used for early flocculation and sedimentation, while cationic polyacrylamide is used for sludge dewatering.
Oil Extraction
It is a core chemical in oilfield production and is widely used in drilling, water plugging, and cementing operations, serving as a lubricant, suspending agent, clay stabilizer, and thickener.
Mineral Processing
In flotation processes, PAM can improve the flotation efficiency of minerals, increasing concentrate grade and recovery rate. It can also accelerate the rapid settling of solid particles in tailings slurries, reducing environmental pollution.
papaermaking
In the paper and textile industries, it is used as a strengthening agent and retention aid to optimize papermaking processes and improve paper strength.

Product FAQ
Everything You Need to Know
How to choose the right type of PAM (cationic/anionic/nonionic)?
It depends on the application scenario and water quality. It is recommended to provide a water quality report or sample so that we can analyze and recommend a model.
What is the dissolution ratio and method of PAM?
Dissolution ratio: usually 0.1%~0.3% (1~3g PAM/liter of water).
Dissolution method: slowly sprinkle into clean water/tap water to avoid lumps, and stir for 40~60 minutes until transparent colloid.
Why does the effect of PAM solution deteriorate after being placed?
Reason: It will degrade after more than 24 hours of dissolution. It is recommended to prepare it and use it now.
Storage tips: Cover the solution to avoid light and store it at room temperature for up to 48 hours.

How to optimize the amount of PAM when dehydrating sludge?
Do a small test first: take 100ml of sludge, gradually increase PAM (0.1~1kg/ton of sludge), and observe the floc size and filtrate clarity.
Overdose consequences: increased viscosity, but decreased dehydration efficiency.
