Liquid silicone poisoning and uncured is a common problem. In order to prevent this phenomenon, the following measures can be taken:
1. Raw materials and storage management
Select high-quality raw materials: Ensure that the quality of the liquid silicone raw materials used is reliable and does not contain impurities or additives that can affect curing.
Proper storage: Store liquid silicone in a dry, cool, well-ventilated environment, avoid direct sunlight and high temperature. At the same time, prevent it from contacting with water, oil, organic solvents and other substances that may affect curing.
2. Production environment control
Keep the workshop clean: Ensure the cleanliness of the production workshop and reduce the presence of pollutants such as dust and impurities. If there are other chemicals or rubber products in the workshop, they should be isolated from the liquid silicone production area to prevent cross contamination.
Regular cleaning and maintenance: Regularly clean and maintain production equipment, tools, etc. to ensure that there is no residue on the surface to avoid affecting the curing effect of liquid silicone.
3. Operation specifications and training
Professional training: Provide professional training for operators to understand the characteristics and operating requirements of liquid silicone and master the correct operating methods.
Standardized operation: During the operation, the operating procedures should be followed, such as avoiding smoking, paying attention to the cleaning and classified storage of labor protection accessories, and keeping the operating environment clean. In addition, liquid silicone should be avoided from contacting with substances that may cause poisoning (such as sulfur-containing, nitrogen-containing, polysulfide compounds, etc.).
4. Quality monitoring and testing
Strict ratio: Ensure that the mixing ratio of liquid silicone and curing agent or other additives is correct and fully mixed. Avoid poor curing caused by improper ratio or uneven mixing.
Regular testing: Regularly conduct quality inspections on liquid silicone products, including testing of curing performance, physical properties, etc. Once a problem is found, the cause should be found in time and measures should be taken to solve it.
5. Emergency treatment and prevention
Develop an emergency plan: Develop a detailed emergency plan for the problem of liquid silicone poisoning and non-curing. Once poisoning and non-curing occur, measures can be taken quickly to deal with it and reduce losses.
Continuous improvement: By summarizing experience and lessons and collecting user feedback, we will continuously improve the production process and operation methods to improve the quality and stability of liquid silicone products.
