It is believed that companies that use butyl reclaimed rubber to produce rubber products are aware that many butyl reclaimed rubber produced by reclaimed rubber factories are marked with "filtered butyl reclaimed rubber," which means that they are filtered during the production of butyl regenerated rubber. The process. So why does butyl reclaim need to be filtered? What is the relationship between filtration and the quality of butyl regenerated rubber products? The following Xiaobian will dig deep in the mystery of “filtering” butyl reclaimed rubber.
In the production process of butyl reclaimed rubber, the filtering is to filter the impurities in the compound through a fine mesh. Butyl reclaimed rubber is usually processed from the waste butyl inner tube. The waste butyl inner tube not only contains butyl rubber, but also contains a large amount of impurities such as reagents, fillers, and metals. If it is not used directly for production, it will be produced. The butyl reclaimed rubber not only has impurities, but also has uneven fineness that directly affects the smoothness of the rubber product itself and its appearance.
In the process of comminution of butyl inner tube, there are many blocky particles that are difficult to be separated, such as metal, fiber, etc. The filter can filter this part of the granules to ensure the uniformity of butyl regenerated rubber products, so the filter is used for production. The fineness of butyl reclaimed rubber is crucial. The purpose of butyl reclaimed rubber filtration is to use different screens to filter according to the fineness of reclaimed rubber products, and to remove large particles, impurities such as metal and fibers that do not meet the reclaimed rubber fineness requirements, so as to ensure the fineness of reclaimed rubber products. . The higher the fineness of the butyl regenerated rubber products, the smoother and brighter the surface of the rubber products produced, and the more beautiful the appearance; the effect of removing impurities, the performance of the rubber products produced will also be greatly improved.
When butyl reclaimed rubber is used to produce rubber products, especially extruded butyl rubber products such as steam pipes, the fineness of butyl reclaimed rubber is required to be very high. It must be filtered through more than 60 meshes before normal extrusion production can be seen. The important role of filtration in the production of butyl regenerated rubber.
