Hydrogenated nitrile rubber hydraulic O-ring is more excellent performance
Hydrogenated nitrile rubber (HNBR) is nitrile rubber in the unsaturated double bond by catalytic hydrogenation made. Hydrogenated nitrile rubber of hydraulic O-ring As the main chain tends to saturation, so in addition to maintaining its excellent oil resistance, rubber elasticity, heat resistance, acid resistance, aging resistance and physical properties are greatly improved. Such as the use of temperature can be as high as 170-180 ?, cold-resistant temperature of -50 to -380 ?. The presence of a small amount of C = C bond allows the hydrogenated nitrile rubber to be sulfur cured. Nitrile rubber is a non-crystalline rubber, but hydrogenated into a tensile crystalline rubber. Hydrogenated nitrile rubber hydraulic O-ring has excellent heat resistance, oxidation resistance and oil resistance, in many ways to replace the fluorine rubber or other special rubber, is widely used in automotive, oilfield mining, aerospace and other industrial fields, as times New Materials of Concern. Hydrogenated nitrile rubber research has made significant progress, successfully developed a new Jan catalyst and its catalytic degradation and hydrogenation, such as technology and processing technology, by optimizing the catalytic hydrogenation conditions for the preparation of hydrogenated nitrile rubber excellent performance.

China nitrile rubber industry market
(1) seize the opportunity to actively develop nitrile rubber production. With the rapid development of China's rubber processing industry, increasing exports of rubber products, nitrile rubber market demand for rapid development, and the current production capacity and production of nitrile rubber still can not meet the actual needs of domestic production, domestic products Of the market share is still very low, the required products are still mainly rely on imports. But with the PetroChina Lanzhou Petrochemical Company 50,000 tons / year nitrile rubber production plant and Ningbo Shunze 50,000 tons / year new nitrile rubber plant put into operation, China's nitrile rubber production capacity will be greatly improved, will greatly Ease the supply and demand of nitrile rubber in China.

Rubber seals from material to size to be able to control in place
Rubber as an ancient material used very early for the ancestors, when most of the rubber can only be used for adhesive and waterproof clothing. Because rubber has a fatal drawback, is too sensitive to temperature. It will become soft and sticky at a slightly higher temperature, and will have a bad odor; [View Details]
Difference between natural rubber and silicone rubber
Natural rubber is the most widely used general-purpose rubber. Wherein the composite rubber and natural rubber are the main varieties of our current imports; natural rubber (nature rubber) is from natural rubber producing plant in the preparation of the rubber. [View Details]
Xinhua Xu seal curing process the most important processes
Xinhua Xu seal variety, but the production process is basically the same. The basic process Xinhua Xu rubber products are mixing, kneading, rolling, extrusion, molding, curing six basic steps. Of course, raw material preparation, product testing, sorting and packaging basic process ultimately. [View Details]
Xu Xinhua rubber seals material performance testing
Xu Xinhua rubber seals according to the general principles of the production of rubber products, the tensile strength must be determined for each batch of feed mix, the elongation at break, tensile permanent deformation, hardness, plasticity, the same drop resistance and other properties. In addition to these basic properties of rubber, rubber shock absorber according to the actual conditions of use, the need to test the following items: a rubber-metal bonding strength, compression set degeneration, brittleness temperature, heat aging resistance, ozone aging resistance, medium Wait.

Reciprocation fluorine rubber hydraulic seals
When fluorine rubber seals and hydraulic friction stainless steel 2Cr13 frictional force curve measurements, analyzes the pressure of the hydraulic seal ring compression ratio and the influence of sliding speed of the hydraulic seal viscous friction. The results show that: with the increase of compression ratio, increased friction fluorine hydraulic seals, and showing a significant rebound characteristics that increased friction and release time lag increases; increases the sealing pressure, which suffered the maximum static friction, sliding friction and hysteresis friction showed a nonlinear variation, and a maximum value exists; reduce speed reciprocating motion, friction value increases, but the extreme value corresponding friction sealing pressure value becomes small.

Vulcanization process quality control hydraulic O-ring
Vulcanization process is one of the main rubber products processing, under heating or irradiation conditions, hydraulic O-ring rubber compounds and raw rubber vulcanizer chemical reaction, the rubber from the crosslinked macromolecular linear structure becomes three-dimensional macromolecular network structure, resulting in physical and mechanical properties of rubber and other properties have been significantly improved, this process becomes vulcanization, along with the development of technology and production, and high-temperature vulcanizing machine is no longer a necessary condition for vulcanization, some compound may be at lower temperatures, even at room temperature and can be cured drinks, some compounds of available physical methods, such as y-rays so that the crosslinked rubber without the need for a vulcanizing agent, vulcanization broader definition so that, under certain conditions , the linear rubber molecules into the process of a network structure.

Production quality hydraulic seals and is closely related to what
Hydraulic seal tensile strength of this material is ultimate tensile load characterization data against corruption. Factors that influence industrial rubber tensile strength more. The first point from the recipe planning thinking, mainly raw rubber species, variety and amount of vulcanizing system and fillers. High tensile strength formulation should be made from natural rubber, neoprene rubber and other crystalline or chlorosulfonated polyethylene, gum content is usually around 60%. It should be a good choice of active filler, and kneading it when you want to slack uniform. [View Details]
