For those who don't know about silicone products, the production process and the properties of the raw materials are a doubt. There is no excessive understanding of the hardness of the product. Secondly, the silicone products are essential to the peripheral products, so it may appear when combined with other materials. The phenomenon that the hardness is low and the performance difference is also unavoidable, so how do you adjust the hardness of the silicone product?
Generally, silicone products manufacturers have different ways to improve the processing process in the process of production. For example, the product is appropriately reduced in temperature during the production of vulcanization. The smaller vulcanization time makes the product softer, and the rubber is glued. Mixing material is more uniform, etc., but if there is a problem with the raw materials, deformation may not occur, so the main reason is caused by raw materials!
The main reason for the lack of stretch rebound in raw materials is that the degree of cross-linking is insufficient when the raw materials are blended. When the cross-linking agent is added, the blending strength is not affected by the precise ratio. If you want to increase the degree of stretching, you must confirm the amount of cross-linking agent and hydroxy silicone oil in the raw materials. The increase in the proportion of hydroxy silicone oil will also affect the product. Therefore, before the processing of silicone products, the performance of different raw materials is known.
The hardness of silica gel raw materials is mainly composed of vinyl with different components, such as silicone, silicone oil, silica, etc., and the content of vinyl is mainly to increase the tightness of the silicon chain (and also need to ingest different components of white carbon). Black, mainly depends on how much hardness you need.) Vinyl is mainly made by blending silicon chains to obtain more crystals while increasing the degree of connection to increase the hardness. On the other hand, 90 degrees is the limit. Currently, silicone rubber There is no better way to improve the hardness of the raw materials of the products!
Due to its excellent comprehensive performance and good technical and economic effects, silicone rubber products have been widely used in aviation, aerospace, atomic energy, electrical appliances, electronics, instrumentation, automotive, machinery, metallurgy, chemical, medical and health, and daily life. application.
