What data for this category looks like
Coatings and inks industry data comes from production formula libraries, raw material quality inspection reports, MSDS safety technical specifications, and downstream application test data. Update timing aligns with raw material price adjustments, formula iterations, and compliance standard updates. No fixed cycle exists. Document structure has two categories: structured parameter tables and unstructured technical documents. Structured fields include viscosity, solid content, density, drying time, and more. These use dedicated units such as mPa·s, %, g/cm³. Unstructured documents are mostly multi-page PDFs. They contain detailed application scenario descriptions and compliance notes.
Constraints on forms and interactions
Dedicated units for structured parameters require forms to pre-set unit options and enforce validation. This prevents input errors that break subsequent matching. Large, multi-page unstructured documents require form upload functions to support large-file and long-document parsing. Parameter classification for multiple application scenarios requires forms to implement linked filtering. Display corresponding fields based on selected application scenarios such as wood coatings, flexible inks. This reduces invalid input entries. Frequently updated data requires the knowledge base associated with forms to support real-time synchronization. This avoids generating marketing content with expired parameters. Marketing forms must collect users’ detailed application requirements. Corresponding fields must be bound to knowledge base recall rules. This ensures generated content matches actual user scenarios.
How to set configurations
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
UPLOAD_FILE_MAX_SIZE | 500 MB | Single coatings and inks MSDS and formula documents can reach hundreds of megabytes. Large-file upload support is required |
PARSE_FILE_TIMEOUT_SECONDS | 120 seconds | Long document parsing takes significant time. This setting prevents parsing from being interrupted by timeout |
form_field_unit_validation | Enabled, enforce matching preset units | Coatings and inks parameters use dedicated units such as mPa·s (viscosity), % (solid content), g/cm³ (density). Enforced validation prevents input errors |
form_field_linkage | Trigger field display based on application scenario | Marketing forms must distinguish between scenarios such as wood coatings, plastic inks. Link to display corresponding parameter fields to reduce invalid input |
retrieval_top_k | Top 6 results | Coatings and inks matching parameters are mostly specific to individual scenarios. A small number of recall results can cover core user needs |
form_submit_pre_check | Enabled, verify required field completeness | Forms include required items such as formula number, raw material batch number. Pre-check reduces invalid submissions |
The parameter values listed on this page are common starting points for configuration. Actual values are affected by material form, data volume, and business rules. Specific issues require individual analysis. It is recommended to test on your own samples before finalizing settings.
Three common mistakes
- Form submission returns an invalid parameter unit error, and logs show field format mismatch. The cause is that the
form_field_unit_validationconfiguration is not enabled, and dedicated coatings and inks units are not enforced for validation. - Uploading an MSDS document fails parsing, and the interface returns a
413status code. The cause is thatUPLOAD_FILE_MAX_SIZEis set smaller than the actual document size, causing file upload to be blocked. - Selecting an application scenario does not display corresponding parameter fields. The cause is that
form_field_linkageis not bound to correct scenario fields and parameter groups, causing linkage rule matching to fail.
How to confirm configurations are correct
- Upload a typical coatings and inks MSDS document. Check if parsed fields correctly extract preset parameters such as solid content and viscosity.
- Select a specific application scenario in the form. Check if only the parameter fields for that scenario are displayed, with no unrelated items shown.
- Use a non-preset unit when entering a parameter. Check if a unit validation error is triggered, confirming the validation rule is active.
- Submit complete required form fields. Check if knowledge base recall or matching marketing content generation triggers normally.
