Because of its excellent thermal conductivity, insulation, shockproof and convenient assembly, silicone caps have been applied in various fields, such as: heating transistors, diodes, audions, switching power supply, uninterruptable power supply equipment, heat dissipation of power amplifiers, heat dissipation of automobile electronic equipment, cooling fins and heat dissipation fins, and other ap...
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 ...
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...
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...
