The main components of liquid silicone include white carbon black, 107 base glue, dimethyl silicone oil, etc., which are all chemical raw materials. In the production process, it is inevitable that various impurities and dust will be mixed in. If these impurities are not removed from the liquid silicone, it will affect the customer's use of silicone to make molds. If there are impurities in the finished silicone mold, it will also affect its service life. So, what should I do if there are impurities in the liquid silicone raw materials?
First of all, during the production process of liquid silicone, if there are many suspended particles in the workshop air or the upstream organic silicone raw materials are not filtered cleanly, it will directly cause the impurity particles to exist in the liquid silicone. At this time, before leaving the factory, the silicone manufacturer will filter multiple processes. Metal filters are used to filter silicone impurities. First, a filter with a large mesh number will be used to filter out larger particle impurities, and then a filter with a small mesh number will be used to filter out small particle impurities.
If the dust at the bottom of the packaging barrel is not cleaned up when the packaging barrel is opened, the silicone is poured in. How to deal with this situation? First, it is recommended that customers use up the silicone on the top first, and when the silicone with impurities at the bottom is used, just use a metal mesh to filter it.
In short, the presence of impurities in liquid silicone raw materials is not a big problem. As long as the correct treatment measures are taken, the quality and use effect of the silicone can be ensured.
