Technical data - vulcanization process of electric butterfly valve
Speaking of which, the first thing that comes to mind is its dark appearance and distinctive smell. So are the products of Shanghai Dongfeng. In fact, there is no smell of nature itself. The smell we usually smell is generated after vulcanization. Before natural vulcanization, the micro structure is mainly linear, and the intermolecular force is mainly van der Waals force, with low stability, which is mainly manifested in low hardness, solubility and other aspects, and cannot fully adapt to the complex use environment. In order to improve the performance of all aspects and adapt to the complex and changing environment, the next process of products is vulcanization.
After vulcanization, it will show different hardness and toughness according to the degree of vulcanization. A really good product can choose a proper balance point between hardness and toughness to maximize the performance of the product. During vulcanization, the physical and chemical properties of
