Understanding Permeability

Permeability inspectie how esily a consule passe thrug a material. Ini adalah kebiasaan yang ekspresif ini adalah sr sr as as as a c / m ²

Calculating Required Thickness

Ini tebal dan jika sebuah barrier film directly afects its permeability.

1f 1f; FLT: 0 123; 123 = (Q × L) / (P × A) 1f; FLT: 1 1f 3; 1f 3;

Dimana:

  • 1f 1f; 1f; FLT: 0 = 33. Q = 1; FLT: 1 = desired permeation rate
  • 1f 1f; 1f; FLT: 0 133; LL 1f; FLT: 1 Aver3; = film lengte
  • 1f 1st; 1f 1; FLT: 0 = 33; P = 1f the materiul
  • 1f 1st; WAL1; FLT: 0 AF3; A PAS1; FLT: 1 ASA3; = area of the film
