The new process carbon black is a new generation of carbon black which is improved on the basis of the traditional carbon black manufacturing process. They first appeared in the early 1970s, when the first variety introduced was N339, a high-structure, high-wear carbon black produced by a new process. Performance characteristics The reason why the…
The milky glue of Gutapo rubber exists in many wild plants, such as dandelion, Eucommia, etc. Although their chemical composition is the same as that of the trilobes, the microscopic spatial arrangement between the units is different, which is trans 1,4 The structure can therefore be regarded as the isomer of the triloba. Gutapo Gum…
The natural rubber is reacted with a cyclizing agent (which may be any one of sulfuric acid, nitric acid, phosphoric acid, chlorosulfonic acid, and benzenesulfonic acid) under heating at 100 to 150 ° C for several hours to several tens of hours. After undergoing the isomerization process, the obtained cyclic molecular structure product is called…
Trefoil rubber (made in Brazil, also known as Brazilian rubber) is the most familiar natural rubber in the rubber industry. In fact, natural rubber with the same composition and similar properties in nature is not the only one, but for various reasons, some natural rubber species do not form scale production, and there are many…
(4) Filling oil composition The effect on the performance of oil-filled rubber varies depending on the composition of the oil. Filling oils are generally refined naphthenic oils and aromatic hydrocarbon oils. Among them, aromatic hydrocarbon oils are classified into two grades of medium aromatic oil and high aromatic oil according to the content of aromatic…
