To prevent silicone from being poisoned and cure inhibition, you can start from the following aspects:
1. Raw material storage and production environment control
Maintain cleanliness: Ensure the cleanliness of raw material storage and production workshops to avoid impurities and pollutants from mixing into silicone raw materials.
Isolated storage: If rubber and silicone workshops coexist, they should be completely isolated, because substances such as vulcanizers in rubber workshops may cause liquid silicone poisoning.
Storage conditions: Silicone should be stored in a dry, cool, well-ventilated place, avoiding high temperature, high humidity and direct sunlight to prevent silicone from deteriorating or performance degradation.
2. Operating habits and training
Train workers: Before operating liquid silicone, workers should be professionally trained to ensure that they understand the characteristics of silicone and safe operating procedures.
Good operating habits: Workers should develop good operating habits, such as washing hands after smoking, paying attention to the cleaning and classified storage of labor protection accessories, and keeping the operating environment clean.
Avoid contact with harmful substances: During operation, liquid silicone should be avoided from contacting substances that may cause poisoning (such as sulfur-containing, ammonia-containing, polysulfide compounds, etc.).
3. Quality Control and Testing
Check the mixing ratio: Ensure that the mixing ratio of silicone and curing agent or other additives is correct and fully mixed to avoid silicone not curing due to uneven mixing.
Regular testing: Regularly test the quality of silicone products, including curing performance, physical properties, etc., to ensure that the product quality meets the standard requirements.
4. Emergency treatment and prevention
Emergency plan: Develop an emergency plan for silicone poisoning and poor curing, including emergency treatment measures after poisoning, treatment methods for uncured silicone, etc.
Preventive measures: Strengthen safety monitoring and inspection during the production process, and promptly discover and eliminate hidden dangers that may cause silicone poisoning and poor curing.
5. Other precautions
Use fresh silicone: Make sure that the silicone used is not expired or has exceeded the shelf life, because expired silicone may have poor curing effect.
Increase curing time: If the silicone cures slowly, the curing time of the silicone can be appropriately increased while ensuring that other conditions meet the requirements.
