What sources of organic pollution should we pay attention to in the OLED production environment?
The investigation of organic pollution in the OLED production environment should be based on the actual use of solvents, adhesives, sealing materials and equipment outgassing. Key components need to be determined based on process sensitivity, and the total number of TVOC cannot be used to represent all requirements.
Create a source list
Material composition, service temperature and degree of openness can provide clues. Specific air loads need to be confirmed under representative operating conditions and avoid inferences based solely on material names.
Check airflow
Contamination may come from fresh air, adjacent processes or within equipment. The inlet, return air and key areas should be compared to confirm whether they have passed through the proposed filter section.
Verify media by ingredient
The adsorption and capacity performance of different organic compounds may be different. Filter material selection, testing methods and replacement targets should respond to key components and equipment requirements.
Project judgment example
When the air composition changes after the introduction of new materials, the material release can be reviewed first before deciding whether to adjust the original organic gas filter section.
Selection check points
Write the following four items into the evaluation record to facilitate product comparison, trial and subsequent review using the same conditions.
| for inspection items | Confirm key points | for inspection items | Confirm key points |
|---|---|---|---|
| source list | Finishing materials and solvents | operating conditions | Record temperature open status |
| key ingredients | According to process sensitivity | Filter verification | Check the corresponding gas performance |
Aili Industrial products and equipment supporting
Aili Industrial provides MAU box-type chemical filters and related clean air equipment. For fresh air or air handling unit projects, the inlet gas, air volume, filter section location and replacement space should be checked at the same time, and the division of labor between particle pre-filtration and gas-phase filtration should be clarified. Aili Industrial's R&D and production of motors and fans, control systems, sheet metal, filters and complete machine assembly capabilities can be used to configure the connection between the filter section and the air supply equipment; the specific gas applicability and performance still need to be confirmed based on the model, filter material and usage conditions.
