Plan a trial for your application
Particle dispersion in recirculating water
At equal hardness and suspended solids loading, compare deposition and filtration.
Mineral slurry dispersion
Keep slurry solids and shear fixed. Compare viscosity and settling on standing.
Purchase specifications and incoming inspection
Use these properties to compare grades within the product family. Example figures refer to the cited grade or source. Confirm the offered specification, packaging and lead time in the quotation. Taihe · Sodium polyacrylate uses and forms ↗
| Property | Unit | Published or agreed specification | Test conditions and checks |
|---|---|---|---|
| Polymer solids | % by mass | Taihe PAAS liquid grade example ≥30%, ≥40% or ≥45% | Select the specific commercial concentration and compare using the same drying method. |
| Average molecular weight | g/mol | Confirm against the offered grade and purchase specification | State the averaging convention, method and calibration basis. |
| Viscosity | mPa·s | Confirm against the offered grade and purchase specification | Specify concentration, temperature and shear conditions. |
When approving a sample, record the grade, methods, limits and specification revision. On receipt, match the packing lot number to the lot-specific COA and record the measured values and release decision.
From samples to commercial delivery
Packaging and receiving
Check drum material, net weight and pumping conditions for solution. Check liner and particle size for powder.
Storage and handling
Agree appearance and viscosity retest conditions for the grade after low-temperature transport.
Sample and order lead times
State treatment scale, trial quantity and acceptable packaging. Request minimum quantities, preparation times and arrival dates for lab samples, pilot lots and routine replenishment.
Questions from the plant
Can PAAS grades be converted using solids alone?
Check molecular weight and degree of neutralisation. Compare dispersion with the same water sample.
Can a superabsorbent sodium polyacrylate be used in a circulating-water system?
Verify water solubility, crosslinking status and stated use before considering substitution.
Report a delivery or batch issue
Include the order number, lot number from the package, label photos and inspection records for the affected lot. When retesting, check Polymer solids, Average molecular weight, Viscosity.
