Penetration yes nickel felt performance of important factor , nickel felt widely used At filter , Battery electrode , catalytic wait Various industry application . permeability yes refer to Material allow liquid or gas flow past That structure of ability . At once nickel felt In terms of , permeability receive several The key factor of Influence , These factor Decide Got it That exist different application middle of effectiveness .
exist analyze nickel felt permeability hour , first need consider factor yes That Porosity . Porosity definition for Material internal allow super fluid or gas circulation open space Proportion . exist nickel felt characteristic middle , high Porosity often and high permeability accompany Follow , This is because exist Even Quite a few path for liquid or gas pass . Decide Certainly Material permeability important detail return include pores size and distributed Condition , thing of state , These factor same right permeability produce Significantly Influence . of great importance , Influence too Pass far-reaching !
nickel felt pores structure and fibrous tissue and Material tight Reality Spend closely related , Can imagine this one characteristic Significantly Influence With fluid or gas pass Should Material difficulty . more open and interconnected pores layout usually meeting bring Even high permeability , on the contrary , impressive revel night sky ! more close accumulation and closed structure So meeting guide To compare Low permeability .
nickel felt of thickness also Influence That Breathability . thicker of Material usually have compare Low of permeability , because fluid or gas pass through Material of distance compare long . However , exist Some need compare high mechanical strength of application middle , possible preferred thicker of nickel felt .
exist Complexity and confusing express middle , key point exist exist : nickel felt surface area right That permeability have Significantly Influence , right thing of effect , Even big surface area mean Even Quite a few fluid or gas flow path , thereby promote permeability . accomplish this One glance mark method include improve fiber density or Construct more open and interconnected structure .
nickel felt Element , dazzling light ! special yes nickel type and very have possible coating or Processing method , deal with matter of method , right Material permeability have Significantly Influence . of great importance , Influence too Pass far-reaching ! different Element meeting bring Various surface characteristic and and fluid or gas interactive difference , abnormal nervous ! and then Influence That permeability able .
nickel felt permeability yes Depend on That Porosity , structure , thickness , surface area as well as Element wait complex factor common effect result , this Decide Certainly Got it That exist different industry application middle performance . for exist specific use Release arrive Highest efficiency and effectiveness , accurate consider These factor right exist design and choose nickel felt arrive close important .
