How to reduce the hazards of VOC (volatile organic compounds) in silicone, you can start from the following aspects:
1. Raw material selection
Choose low-VOC silica gel raw materials: When preparing silica gel products, you should give priority to low-VOC or no-VOC silica gel raw materials. These raw materials release less VOC during the production process and can significantly reduce the VOC content of the product.
Avoid using highly volatile additives: In silicone formulations, avoid using additives containing highly volatile or easily volatile substances, such as certain silicone oils or additives. These additives may gradually evaporate during the use of silicone products, increasing the amount of VOC released.
2. Production process control
Optimize the production process: Reduce VOC volatilization and leakage by improving the production process. For example, increase the number of exhausts during the mixing process to eliminate gases and volatile substances generated during the mixing process; during the vulcanization process, reasonably control the amount of vulcanizing agent and vulcanizing temperature to avoid excessive vulcanizing agent or too high vulcanizing temperature. Lead to an increase in volatile substances.
Use environmentally friendly processing aids: Choose environmentally friendly processing aids to replace traditional high-VOC additives to reduce VOC emissions during the production process.
3. Product design and packaging
Reasonable design of product structure: When designing products, the use environment and functional requirements of the product should be fully considered, and the product structure and sealing performance should be reasonably designed to reduce the release of volatile substances. For example, for silicone products that need to be sealed, good sealing performance should be ensured to prevent VOC from leaking from the seal.
Choose packaging materials with good sealing properties: In terms of packaging, you should choose packaging materials with good sealing properties, such as aluminum foil bags, vacuum bags, etc., to ensure that silicone products are not affected by the external environment during transportation and storage and reduce the release of VOCs .
4. Storage and use environment control
Choose a suitable storage environment: Silicone products should be stored in a cool, dry, and well-ventilated environment to avoid adverse conditions such as high temperature, humidity, and direct sunlight that accelerate the volatilization of silicone products.
Reduce the time of contact with air: Silicone products that have been opened should be used as soon as possible and properly sealed and stored to reduce the time of contact with air and reduce the amount of VOC released.
5. Strengthen supervision and testing
Develop and implement strict VOC testing standards: Relevant regulatory authorities should strengthen supervision of silicone product manufacturers and urge them to strictly abide by relevant standards and specifications for production. At the same time, strict VOC testing standards are formulated and implemented to ensure that the VOC content in silicone products meets environmental protection requirements.
Promote environmental certification: Encourage companies to apply for environmental certification, such as ISO 14001 environmental management system certification, etc., to enhance their environmental awareness and level.
