The platinum two-component mixing method:
1. Put the silica gel in a rubber mixing machine and mix until it is softened. Additives such as pigments can be added during this process.
2. After the softened rubber material, silica gel and agent B are mixed evenly, let it cool down.
3. Take agent A and add it to the silica gel that has been mixed with agent B several times in batches, and mix evenly.
4. It can be used for forming operation after being allowed to cool down.
During the mixing process, try to keep the temperature of the rubber mixer roller not exceeding 35℃. It is recommended that the mixer use refrigerated water circulation when the temperature is high, and measures such as air conditioning to control the ambient temperature should be adopted to reduce the mixing temperature.
1. It is forbidden to add substances such as nitrogen, phosphorus, sulfur, lead, cadmium, polyvinyl, polyethynyl, etc., because the above substances can poison platinum and fail to achieve the purpose of crosslinking.
2. Certain organic silica gel pigments can also cause platinum poisoning and invalidation and cannot be used. Therefore, when selecting platinum vulcanizing agent for production, a small test must be carried out to confirm that it is feasible before use.
3. After mixing the colloid with platinum vulcanizing agent, it is recommended to vulcanize and form within 4 to 8 hours to prevent crosslinking at room temperature. If you need to extend the storage time, you can add a little delay agent. (Our model FM-10)
4. When there is hydrogen-containing silicone oil in the silica gel, mixing Agent A separately will cause the rubber compound to die.
5. When using different types of silica gel, the proportions of A and B added are different. If you have any questions, please call our sales staff for consultation
