Since silicone rubber has been widely used in people's life and production, and the price of silicone rubber is relatively expensive, the product is excellent and has many excellent characteristics, so the regenerated silicone rubber also emerged. The reclaimed silicone rubber is recycled through technological means. Silicone rubber is used for regeneration technology. Such recycling can reduce the company's production costs and save raw materials. Now it has been applied to many manufacturers engaged in the production of silicone rubber raw materials.
Recycled silicone rubber process:
The main process of reclaimed silicone rubber includes the selection of old materials to remove impurities from the product, followed by selection and classification of silicone rubber products, followed by dicing and cracking.
Recycled silicone rubber notes:
First, the production of recycled silicone rubber should pay attention to changes in temperature, it should be to control the temperature increase slowly, this can prevent the silicone rubber particles burst due to the sharp changes in temperature;
Second, the regeneration of silicone rubber is generally required to remove the small particles inside the silicone rubber, so that it can be homogeneous rubber particles of recycled silicone rubber, improve the quality of recycled silicone rubber;
Third, the temperature is too high will cause changes in the pore structure of silicone rubber and significantly reduce its adsorption effect, affecting the value of use. For the blue plastic indicator or discolored silica gel, the desorption regeneration temperature should not exceed 120 °C, otherwise it will lose color because of the gradual oxidation of the color reagent.
Disadvantages of recycled silicone rubber:
The regenerated silicone rubber has less elasticity, elongation and tear strength than the unregenerated silicone rubber material. The regenerated silicone rubber also has a relatively high hardness and is used for a long time. Tiny deformations will also be found.
