| Stability | No attenuation when long-term use | Ensure the life of the equipment |
3. Effect of PU soft amine catalyst on drug quality
3.1 Source of drug contamination
Drug pollution mainly comes from the following aspects:
- Equipment Materials: Impurities in the equipment materials may penetrate into the medicine.
- Manufacturing Process: Improper manufacturing process may lead to drug contamination.
- Catalytics: The impurities in the catalyst may directly contaminate the drug.
3.2 PU soft amine catalyst guarantees the quality of drug
By using high-purity and high-stability PU soft foam amine catalysts, the risk of drug contamination can be effectively reduced and the quality of drug can be guaranteed.
| Safeguards | Specific content | Effect |
|---|---|---|
| High purity | Use catalysts with ≥99.9% purity | Reduce impurity pollution |
| High stability | No attenuation when long-term use | Ensure stable equipment performance |
| Precise control | Precisely control the reaction speed | Ensure uniform foam structure |
IV. Selection and use of PU soft foam amine catalyst
4.1 Selection criteria
When choosing a PU soft foam amine catalyst, the following criteria need to be considered:
- Purity: Choose a high-purity catalyst to avoid impurity contamination.
- Reaction speed: Choose the appropriate reaction speed according to the equipment requirements.
- Stability: Choose a catalyst that has no attenuation for a long time.
4.2 How to use
When using PU soft foam amine catalyst, the following points should be paid attention to:
- Combination: Use strictly according to the ratio to avoid excessive or insufficient amount.
- Temperature Control: Control the reaction temperature to ensure uniform reaction speed.
- Stir: Stir thoroughly to ensure even distribution of the catalyst.
5. Future development trends
5.1 Environmentally friendly catalyst
With the increase in environmental protection requirements, more environmentally friendly PU soft foam amine catalysts will be used in the future to reduce environmental pollution.
5.2 Intelligent control
Through the intelligent control system, the reaction speed and temperature of the catalyst are accurately controlled, and the accuracy and stability of equipment manufacturing are improved.
Conclusion
PU soft foam amine catalysts play a crucial role in the manufacturing of pharmaceutical equipment. By strictly selecting and using high-purity and high-stability catalysts, the quality of drugs can be effectively guaranteed and the risk of pollution can be reduced. In the future, with the development of environmental protection and intelligent technologies, PU soft foam amine catalysts will play a greater role in the manufacturing of pharmaceutical equipment.
