The leakage of transformer occurs mostly around the gasket, which is mainly caused by the aging and cracking of gasket. The quality of depends mainly on its oil resistance. The poorer oil resistance, the faster aging rate. Especially under high temperature, the aging speed will be faster and easily lead to aging and cracking of gasket, resulting in oil leakage. When overhauling oil-resistant and h...
Rubber hoses can be divided into these types according to their applications: 1. Rubber hoses for cooling and insulation: This type is usually used for water delivery in horticultural irrigation, building ‘s fire prevention, tank car cleaning, industrial sewage drainage, etc. 2.High pressure steam rubber hose: Generally, the hose is used to cooling water in cooling equipment or engine, and food pr...
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...
