Plan a trial for your application
Laundry powder builders
At actual hardness and wash cycle, compare cleaning and residual calcium.
Granular detergents
Check particle uniformity, finished-powder flow and powder residue on fabric.
Purchase specifications and incoming inspection
Review these properties for the intended application grade. Example figures refer to the cited grade or source. Confirm the offered specification, packaging and lead time in the quotation. Grupo IQE Siolite · Detergent zeolite 4A ↗
| Property | Unit | Published or agreed specification | Test conditions and checks |
|---|---|---|---|
| Calcium exchange capacity | mg CaO/g | Agree for the grade and end use | State dry basis, temperature and contact time. |
| Particle size distribution | µm | Agree for the grade and end use | Describe dispersion conditions and the coarse end of the particle distribution. |
| Moisture | % by mass | Agree for the grade and end use | Test at the temperature and for the duration agreed by both parties. |
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
Use moisture-resistant bags and confirm net weight, size and dust controls. Distinguish detergent powder from adsorbent desiccant.
Storage and handling
Retain a representative sample of the complete lot and state the moisture basis. Compare cost on an active dry basis.
Sample and order lead times
State the concentration or hydrate, initial net quantity, destination and unloading method. Confirm minimum order, pallet or truckload quantity, dispatch point and arrival date separately.
Questions from the plant
Why is soil removal poor despite high exchange capacity?
Check exchange rate within the short wash cycle, calcium-to-magnesium ratio and surfactant system.
Why are white spots left on dark fabrics?
Check coarse particles, powder dispersion and rinse count. Include a blank fabric.
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 Calcium exchange capacity, Particle size distribution, Moisture.
