Wet-grinding quotation / Rheology evidence
A value reported in cP or mPa·s may describe a different property, instrument, geometry, speed, shear condition, temperature, sample point or conditioning history from the value beside it. Preserve the complete test basis before a candidate supplier uses rheology data in a wet-grinding review.
Do not compare orphan viscosity values
This page owns the measurement and sample-state basis for viscosity and rheology evidence. Agitator mechanism, mill cooling, flow, residence time, separator, specific energy, throughput and equipment selection remain separate decisions.
Preserve the laboratory's property name and original unit. A single-point apparent-viscosity result, a flow curve and a time-dependent sequence are not interchangeable records, even when a summary column uses the word viscosity.
Keep the standard or method edition, instrument, geometry or spindle, speed or controlled shear condition, temperature, duration and validity status together. A converted unit does not repair a missing method or condition.
Identify formulation revision, sample point, process state, sampling time, preparation, conditioning, pre-shear or rest history and delay before testing. Feed, discharge and aged samples must not be merged into one unlabeled value.
Record-to-record comparison
The table is an evidence register, not a test method or operating instruction. The buyer, laboratory and candidate suppliers must approve the project-specific method and use of the result.
Swipe or scroll horizontally to review every evidence column.
| Audit row | Record A | Record B | Release evidence |
|---|---|---|---|
| Property and original unit | Named reported property, original unit, single-point or sequence identity and any conversion record. | Same fields retained independently; no equivalence is assumed from a shared viscosity label or converted unit. | Declared comparison purpose, accepted property basis and unresolved terminology differences. |
| Method, instrument and geometry | Method or standard edition, laboratory procedure, instrument and model, geometry, spindle or accessory configuration. | Corresponding controlled records plus calibration or quality-control status and any deviation. | Laboratory review of comparability, method limitations and required repeat or bridge evidence. |
| Speed, shear rate or stress condition | Rotational speed, angular velocity, reported shear rate or stress-control condition exactly as recorded by the method. | Corresponding imposed condition, sequence direction and read point; no unverified conversion is inserted. | Confirmed like-for-like condition or a documented reason the results answer different questions. |
| Temperature and equilibration record | Measured sample temperature, measurement point, control basis and recorded equilibration status. | Matched fields with time stamps and deviations preserved rather than normalized silently. | Approved temperature basis and statement of any remaining comparability limitation. |
| Sample, conditioning and time history | Formulation revision, sample point, process state, preparation, pre-shear, rest, aging, delay and test timing. | Same chain recorded for the comparison sample, including any handling or sequence difference. | Traceable sample map, controlled history and disposition of non-comparable or missing states. |
| Raw record, validity and release | Raw readings or curve, repeats, instrument range or torque status, uncertainty, stability rule and deviations. | Corresponding raw evidence and quality checks, not only a rounded summary value. | Named laboratory, process and supplier reviewers, conclusion, limitations and revalidation triggers. |
Evidence route
Freeze the material and question, preserve the complete measurement basis, map the sample state, then release the record only for its approved comparison purpose.
State the decision question, product or formulation revision, sample point, process state and property needed before collecting values.
Attach method, instrument, geometry, imposed condition, temperature, conditioning history and timing to every result.
Retain raw evidence, repeats, range or torque status, quality controls, uncertainty and deviations for laboratory review.
Record what the evidence can support, what remains non-comparable and which product, method or process changes reopen the review.
Rheology-basis RFQ checklist
Unknowns remain explicit questions for the buyer's laboratory and candidate suppliers. These fields do not prescribe a method, set an acceptance limit or authorize an operating condition.
Open the process briefProduct identity, formulation or batch revision and the controlled document or sample reference used for comparison.
Feed, mill discharge, loop, finished product or other identified point, plus time, campaign state and sampling record.
Solids basis, liquid phase, pH or other chemistry that the responsible reviewers consider relevant to the result.
Exact property name, single-point or sequence basis, original reported unit and any separately traceable conversion.
Named internal method or published standard, edition, laboratory procedure revision and declared applicability.
Manufacturer, instrument or system designation, model, equipment ID and software or configuration record where relevant.
Measuring geometry, spindle, fixture or accessory identification and the controlled configuration record.
Container and sample-volume basis, immersion or guard configuration and any documented limitation or deviation.
Rotational speed, angular velocity, reported shear-rate field or controlled-stress condition exactly as recorded by the method.
Observed sample temperature, measurement point, control and equilibration record, timing and deviation status.
Sample preparation, mixing, conditioning, pre-shear, rest, aging and transfer history retained as method records, not instructions.
Sequence duration, selected reporting point, laboratory stability or equilibrium rule and actual observed status.
Instrument range or torque indication, calibration or quality-control status, validity conclusion and deviations.
Record type, sequence direction, hold or recovery segment identity and which part supplies the reported result.
Raw readings or curve, repeats, variation, uncertainty where reported, excluded results and the reason for exclusion.
Relationship among samples across process points, batches, passes or circulation time, including missing or non-comparable states.
How each candidate proposes to use the record, stated limitations, assumptions, additional evidence needed and unresolved questions.
Named laboratory, process and supplier reviewers, approved use, open limitations and changes that require a new review.
Draft source record / Pending technical review
These current first-party sources were reviewed on 1 August 2026. They support the vocabulary and record structure for rotational rheometry, apparent viscosity, method conditions, temperature and sample history. Their methods, instruments, values and product statements remain source-specific.
Buyer decision FAQ
No. Even when units are equivalent or converted correctly, the results can represent different properties, methods, geometries, speeds or shear conditions, temperatures and sample histories. Compare the complete test record and intended use.
Its reported apparent viscosity can depend on the imposed measurement condition and on time, temperature and conditioning history. Preserve the method, instrument, geometry, condition, sequence and sample state rather than averaging unmatched values.
No. A single point records one declared method condition, while a flow curve records a sequence across controlled conditions. State which record answers the project question and retain the raw evidence and limitations.
No. A controlled rheology record can inform engineering review, but product composition, solids, particles, media, flow path, thermal behavior, cleaning, endpoint and project constraints remain separate inputs for the responsible suppliers.
Only after sample identity, process state, timing, temperature, preparation, conditioning and method are controlled. Milling, temperature change, time history and sampling can alter the state represented by each result.
No. It publishes an RFQ and evidence framework only. Any JINPIONEER equipment limit, method, instrument, control, compatibility, selection, result or performance remains unconfirmed until supported by project-specific supplier and buyer evidence.
