How to avoid the delamination of silicone materials
To avoid the delamination of silicone materials, it is necessary to consider the material selection, preparation process, operation process and storage environment. Here are some specific suggestions:
Selection of high-quality materials:
Select silicone raw materials with reliable quality and high purity. Low-quality silicone often contains more impurities and unstable components, which increases the possibility of delamination.
If different types of silicone need to be mixed or fillers need to be added, good compatibility between the components should be ensured.
Optimize the preparation process:
During the preparation process, ensure uniform mixing to avoid local concentration differences.
Control the reaction temperature and time to ensure that the silicone is fully cross-linked and cured to form a stable network structure.
For silicone that needs to be heated and cured, the heating curve should be strictly controlled to avoid performance degradation due to overheating or insufficient heating.
Improve the operation process:
When using silicone for screen printing or other processing, ensure that the operation is standardized to avoid mechanical damage or chemical erosion to the silicone.
Regularly check and maintain production equipment to ensure the accuracy and stability of the equipment and avoid the degradation of silicone processing quality due to equipment problems.
For silicone products that need to be coated or molded, ensure that the surface of the substrate is clean and dry, and select a suitable adhesive or tackifier to improve adhesion.
Control the storage environment:
Store the silicone in a cool, dry, ventilated place, away from direct sunlight and high temperature environment. High temperature will accelerate the aging process of silicone and reduce its performance stability.
Avoid contact between silicone and corrosive substances such as acids and alkalis to prevent it from being corroded and delaminated.
For silicone products containing a large amount of fillers (such as thermal conductive silicone), they should be stirred regularly to prevent filler sedimentation and delamination.
Quality inspection and monitoring:
During the preparation and use of silicone, regular quality inspections, including appearance inspections, performance tests, etc., are carried out to ensure that the quality of silicone meets the requirements.
Establish a quality monitoring system to monitor and adjust key parameters in the production process in real time to ensure the stability and consistency of product quality.
Training and awareness enhancement:
Provide professional training for operators to improve their professional skills and quality awareness so that they can operate equipment and handle silicone materials correctly and in a standardized manner.
Strengthen the construction of quality culture so that all employees are aware of the importance of quality and actively participate in quality improvement activities.
