Many people who have purchased silicone products have found that the silicone products they just purchased will have some odors, so are there any quality problems with these silicone products, and how are these odors generated. How to remove the odor on silicone products?
Anyone who knows about silicone products knows that good silicone raw materials are non-toxic and tasteless, but in the production process, they will go through processes such as adding color masterbatches, fluidizing agents, and high-temperature molding by hydraulic presses. A little odor is produced, which is a normal phenomenon, not a problem with the quality of silicone products. In fact, the solution to this problem is very simple, as long as it is placed in a ventilated place for 2-3 days, the smell will disappear.
But to really remove the unpleasant odor of silicone products, the best way is to optimize the selection of silicone raw materials and the vulcanization process.
1. Silica gel raw materials and production and processing: In order to reduce costs, some silicone product manufacturers often increase a certain share of recycled silica gel, and at the same time also increase a certain share of polluting operating oil; however, these must use environmentally friendly, tasteless and good for silica regeneration. Polluting volatiles have to inhibit and degrade the process oil to complete. Therefore, we need to deal with the odor of silica gel products on the basis of selection from the raw materials and production and processing of silica gel.
For example: choose oil with high flash point and odorless; do not add reclaimed rubber; do not use accelerator CBS; do not use DCP, etc.
2. Vulcanization system and process: Silica gel is a gas-phase glue, and is mixed with an odorless vulcanizing agent, and the silica gel is formed after secondary vulcanization.
