EPDM Membrane Production: Materials and Manufacturing Processes
ثبت نشده
چکیده
Because these reactive sites are pendant (not part of the main backbone chain) there are no weak points on the main chain. This is unlike for example Natural Rubber or SBR, where these necessary reactive sites are along the main chain. This means that reactive entities in the atmosphere (for example Ozone, which is very aggressive) can easily attack and degrade these materials. This also explains why EPDM is on the order of 100 to 1000 times more resistant to ozone than Natural Rubber, even containing antiozonant stabilizers.

Thermoplastic elastomers are a special class of polymeric materials that combine the properties of thermo plasticity during processing and rubber-like behaviour in service. They can be processed in conventional plastic processing equipment, such as twin screw extruders, internal batch mixers, extruders and injection moulding machine, but exhibit vulcanized rubber like ultimate properties (i.e. ...
متن کاملMembrane Biological Reactors (MBR) and Their Applications for Water Reuse
The term 'membrane bioreactor' expresses a combination of activated sludge and membrane separation processes. The need to processes like sedimentation and disinfection used in common methods is eliminated through MBR systems in a way that membranes are placed into or out of an aeration tank and the vacuumed wastewater created by the suction pump is pulled up from inside the membranes and leaves...
