SSI Microporous Aerator

The standard of low plastic EPDM (three Yuan rubber)

EPDM is a synthetic rubber products according to customer demanddevelopment use. Relying on its unique compound composition andpressure molding process, the diaphragm can maintain its physical properties, tearing at the minimum pressure under long time, through the cycle of operation for several years still keep in shape, resulting in microbubbles. Our EPDM membrane products has already been tested in a variety of municipal and industrial wastewater treatment applications, the effect is excellent. However, for solvent, grease, or grease and high concentration of metal salts of the occasion, does not recommend the use of the standard type EPDM.

Coating PTFE (polytetrafluoroethylene) and VITON coated EPDM

PTFE and VITON is a synthetic rubber commonly known as fluorine rubber. They have a wide tolerance for a variety of chemicals, can cause damage to the traditional rubber solvent, oil, grease, and is recognized as a material with excellent performance. However, the disadvantage is the price expensive. Therefore, SSI is used to develop fluorine rubbercoating, through the realization of its permanent combination with EPDMsurface or other substrate material of patent technology, practice has proved that this is a kind of effective method. The new technology of SSImakes the film not only keeps the excellent physical properties of traditional rubber material, and has the world's most advanced rubbermaterial to some chemicals, solvents and fat tolerance performance, and you can afford the cost of. Many once due to calcium deposition and solvent rot

Caused by the sewage treatment plant membrane damage has been demonstrated, SSI model with PDM diaphragm fluorine rubber coatingproduced is not in use process scaling, also won't cause any change of material properties.

Silicon rubber and polyurethane

Before the SSI to develop the fluorine rubber diaphragm, for sewage treatment plant scale exists, a sewage treatment plant or chemicalsolvent oxidation phenomena caused by rubber, silicone rubber andpolyurethane was the two major alternative materials. Although SSI is now the production of silicon rubber and polyurethane film, however, we are more optimistic about the various performance fluorine rubberdiaphragm, because the silicon rubber and polyurethane as time goes on, because of bending failure caused the tear, which for the EPDMdiaphragm is not what effect. Whether it is a polyurethane or silicone rubber are not suitable for circulating operation, nor do they than fluorine rubber coated EPDM more cost saving.
