DME-resistant rubber sealing material standards

From Yunnan Coal Chemical Institute of Applied Technology released the "dimethyl ether rubber sealing material" corporate standard at June 1, 2010 implementation. This is currently the dimethyl ether rubber sealing material products first corporate standards.
Yunnan Institute of Applied Technology in formulating released "dimethyl ether rubber sealing material" corporate standard, the DME-resistant rubber material is divided into A and B categories.plastic truck seals A class suitable for long term or full contact with the case of DME, such as liquefied DME cylinder valve cylinder; B class or parts suitable for intermittent contact with the case of use of dimethyl ether, such as adjusting the valve or valves. Standard proposed product of the technical control indicators, DME-resistant rubber sealing material product quality to provide a detection method and the application of judgment basis.
New DME rubber sealing material and the successful development of "dimethyl ether rubber sealing material" corporate standard release, will be conducive to dimethyl ether product application and promotion.
Currently, DME as a clean fuel has been widely recognized. Since the conventional DME liquefied petroleum gas, diesel and other physical and chemical properties of the fuel there is a big difference in resistance, the sealing material as a constraint DME DME application is an important factor. To this end, Yunnan Academy of play in the rubber research in technology, research and development of new thematic groups established DME-resistant rubber seal materials research through several tests, to obtain better results. self-locking cable ties They have developed resistance to dimethyl ether rubber sealing material by Yunnan Rubber Product Quality Supervision and Inspection Station and the National Gas Appliances Quality Supervision and Inspection Center, the performance indicators meet the sealing material material requirements, especially in the anti-media volume change rate and quality changes rates have a greater breakthrough.
