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...
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...
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...
The process of converting plastic rubber to elastic rubber is called vulcanization. It is to add a certain curing agent such as sulfur, curing accelerator and so on into the semi-finished products made of raw rubber. In the vulcanization tank in the specified temperature heating, heat preservation of the raw glue between the linear molecules linked to each other into a three-dimensional network st...
Vulcanized elastic rubber is called vulcanized rubber, also known as soft rubber, commonly known as "rubber". Vulcanization is one of the most important technological processes for rubber processing. All kinds of rubber products must be vulcanized to obtain the ideal performance. Unvulcanized rubber in use is not of use value. But insufficient sulfur or curing time is not enough to make...
With the increase of room temperature vulcanization materials and the appearance of high temperature vulcanization, the vulcanization temperature tends to two extremes. From the improvement of curing efficiency, it should be considered that the higher the curing temperature, the better. But in fact we can not infinitely increase the curing temperature. Rubber is a high polymer, high temperature wi...
