Preventing Airborne Particle Accumulation on PE-PP Membranes
NineSigma, representing a leading consumer goods manufacturer, invites proposals for solutions ortechnologies that repeldust or prevent the accumulation of dust particles on porous polyolefin fiber-based membranes.
NineSigma’s client, a leading consumer goods manufacturer, uses porous polyolefin-based membranes that prevent dust from traveling within an air stream. The membranes are made of polyethylene (PE) fibers or a mix of polyethylene (PE) and polypropylene (PP) fibers. One of the major drawbacks of these porous membranes is that dust particles tend to accumulate quickly on the outer side of the membrane, thereby affecting the airflow through the porous membrane. The increased resistance reduces the efficiency of the entire system and leads to increased maintenance requirements.
In order to improve the efficiency and the service life of the membrane, our client is looking for methods or technologies, chemical or physical, that reduce or prevent the accumulation of dust particles to the surface of the porous membrane.
The objective of this RFP is to find solutions that reduce or prevent the accumulation of dust on porous polyolefin-based membranes.
Key Success Criteria
The successful solution has to:
Reduce or prevent the accumulation of dust on porous polyolefin-based membranes
Be proven on lab scale
Be resistant to water at 40 °C
Be safe for human contact
After additional development, the solution has to:
Be scalable to industrial quantities
Possible approaches might include, but are not limited to:
Hydrophobic or oleophobic coatings
Surface micro-structuring or nano-(composite) coatings
Anti-fouling/ anti-adherent coatings or surface treatment
Oil-free Lubricious coatings
Other permanent chemical surface treatments
An additive for incorporation into coating formulations
Physical approaches that allow frequent removal of the adhered particles
