A lower quotation and a good settling jar are not complete approval for an anionic PAM supplier change. The replacement must preserve the operating result and work with preparation and delivery. Progress from a traceable sample comparison to limited plant evidence and an identifiable first shipment.
Retain the incumbent baseline
Identify the present grade, lot, preparation water, stock concentration and solution age. Test the reference with each candidate on the same representative feed. A historic result from a different ore or water condition may not establish equivalence. Record how samples are split and handled so the apparent advantage cannot be explained by missing fines or unequal preparation. Keep the candidate code visible in every result.
Compare the useful response range
Normalize dose and evaluate the relevant water, bed, underflow or filtration endpoints. Include practical preparation and measured delivery. A replacement that works only at one narrowly controlled point may increase operating risk or cost. The selection guide supports the initial screen, while dosing-system compatibility addresses whether the candidate can be used consistently.
Run a controlled production introduction
Agree trial conditions, responsible operators and a practical fallback with the plant. Keep the equipment baseline and allow the appropriate residence before sampling. Do not blend candidate and incumbent in a preparation tank merely to simplify stock use. Record normal and relevant difficult feed periods. A brief easy run should be described as limited evidence rather than approval of the complete supply-period envelope.
Match the first shipment to the qualified identity
Confirm product code, lot documents and package condition before release. Require clarification of any substitution from the tested candidate. Preserve the approved preparation and operating range with the order. Purchasing may negotiate while technical acceptance is still pending; those decisions should remain separate. If the supplier proposes a materially different product or the feed changes, use a new comparison instead of assuming that the former grade name proves equivalence.
Record the purchase decision
Complete the following checks with actual measurements, observations or an agreed document reference. Keep an untested condition visible as a limitation rather than assuming equivalence. The candidate code, sample identity and trial method must remain attached to the decision so purchasing and operations approve the same product and duty.
| Check | Evidence | Order decision |
|---|---|---|
| Reference | Incumbent identity and paired preparation | Baseline is reproducible on the same feed |
| Operating result | Dose window, equipment and compatibility evidence | Replacement fits the stated duty |
| First lot | Code, documents and condition | Delivered product matches the accepted candidate |
Send a useful sample and quotation enquiry
Send incumbent information, candidate dose curves, feed and water range, preparation and machine results. State whether bench, limited plant or full production approval is complete. Include the proposed first-order scope and any condition that still needs verification before a bulk commitment.
Include quantity, packaging preference and destination separately from the technical approval. Use the anionic PAM sample worksheet to define the candidate screen and confirm quality documents and delivered supply scope for the selected identity. Gongyi Xinqi Polymer Co., Ltd. can review the requirements. Availability, commercial terms and application suitability require confirmation; a process name does not establish a universal dose or guaranteed operating result.
Request a focused sample review
Send solids, water, separator and purchasing requirements for this duty.
