Vulcanization of silicone rubber hand plate refers to the vulcanization of silicone rubber without vulcanization under the conditions of vulcanization time, vulcanization temperature and pressure. The process of chemical crosslinking of silicone rubber molecules. What about the vulcanization time and temperature of silicone rubber hand board?
Vulcanization temperature is the premise of silicone rubber vulcanization reaction. The temperature directly affects the vulcanization speed and quality of products. The higher the vulcanization temperature is, the faster the silicone rubber molecular crosslinking reaction speed is, and the higher the production efficiency is. On the contrary, the lower the temperature, the slower the reaction speed and the lower the production efficiency. The vulcanization temperature depends on the type and vulcanization system of silicone rubber.
Low temperature vulcanization is good for product performance, but it will affect product output, because the lower the temperature, the slower the reaction speed and the lower the production efficiency. On the contrary, high temperature will improve the production efficiency, but will affect the quality of products. Too high temperature will cause problems such as slight scorch, brittleness and difficult edge removal of silicone rubber products, which will affect the physical and mechanical properties of silicone rubber hand board.
Therefore, the enterprise will fix the temperature and vulcanization time during production. In addition to paying attention to the product output, the enterprise also pays attention to the product quality. Therefore, before the new mold is put into production, it will try out a reasonable vulcanization temperature to improve the production efficiency and quality.
In addition, before the production of the hand board, it is necessary to plan the production process, materials, accuracy, size and other issues of the hand board, communicate with customers before processing, and make rational use of various materials, including human and material resources. Be careful when Machining NC with the hand board. The fixture should be fixed well and the tool setting should be accurate. Only in this way can the hand board have high precision and small error.
Jinan hand board manufacturers remind that the hand board needs careful treatment in the post-processing. Strictly control the quality of grinding, surface strengthening treatment, painting, etc. Especially in the process of polishing, only when the surface of the hand board is polished smoothly can we get twice the result with half the effort. In order to improve the grinding effect, it is necessary to use coarse sandpaper to polish first, and then use fine sandpaper to polish, so that the polished surface will be very smooth.
