In order to adapt to different conditions of use and obtain different properties, and to improve the performance of rubber products and reduce the cost, different additives must be added into the raw rubber.Rubber mixing and refining is a process in which the plasticized raw adhesive is mixed with the binder and put in the mixer to make the binder completely and uniformly dispersed in the raw adhe...

Raw rubber is elastic and lacks the plasticity necessary for processing, so it is not easy to process. In order to improve its plasticity, it is necessary to plasticize the raw rubber, so that the coordination agent can be easily dispersed in the raw rubber in mixing process. Meanwhile, in the rolling and forming process, it is also helpful to improve the permeability of the rubber into the fabric...

There are many kinds of rubber products, but the production process is basically the same. The basic technological process of rubber products with general solid rubber as raw material includes six basic processes: plasticizing, mixing, calendering, pressing, forming and vulcanizing. Of course, raw material preparation, finishing, inspection and packaging and other basic processes are also necessar...

Rubber is widely used in daily life, but some of its elements are prone to external interference and instability, which brings us serious problems in daily use and factory processing. The most obvious problem is the yellowing of rubber. The essence of rubber yellowing is the deterioration of the physical and chemical properties and mechanical properties of rubber in the process of processing, stor...

A rubber bushing is a highly elastomer component that can be made from ordinary rubber. The elastic modulus of rubber bushing is small, and the elastic deformation is large after being loaded, so as to absorb impact and vibration. It can be subjected to multiple loads at the same time, but its high temperature and oil resistance is worse than that of steel bushings. The shape of rubber bushi...

In the process of storage and use of rubber, affect by the environment and human forces, the performance and appearance of rubber changes with time, which is the phenomenon of aging. So what causes rubber to age? There are mainly 7 factors as followed: 1.Oxygen: free radical chain reaction will occur between oxygen and molecules of rubber when molecular chains fracture or over cross linked, which ...

Tetrafluoro-flange gasket is a kind of non-metallic gasket, which is generally composed of two parts: cladding layer and embedded material. The cladding layer is corrosion resistant and is usually made of polytetrafluoroethylene (PTFE) with inserts (fillers) that are more resilient and are usually asbestos rubber sheets. The sealing gasket can be made into V-shape, U-shape and L-shape according to...
