1. Introduktion af TQD-01 Air Permeance Tester<\/h2>\n

TQD-01 Luftgennemtr\u00e6ngelighedstester<\/strong>\u00a0bruges til at bestemme luftgennemtr\u00e6ngeligheden for papir og karton i omr\u00e5det for middel luftgennemtr\u00e6ngelighed ved hj\u00e6lp af Schopper-metoden.<\/p>\n

Metoden kan anvendes p\u00e5 papirer og plader med luftgennemtr\u00e6ngelighed mellem1\u00d710-2~1\u00d710\u00b2um\/(Pa.S). Metoden er uegnet til papirer og plader med ru overflade, som f.eks. kreppede og b\u00f8lgede papirer, som ikke kan fastsp\u00e6ndes sikkert for at undg\u00e5 l\u00e6kage.<\/p>\n

TQD-01 Luftgennemtr\u00e6ngelighedstester<\/strong>\u00a0kan ogs\u00e5 bruges til andre materialer som f.eks. cementposepapir, papirposepapir, kabelpapir, kopipapir, industrielt filterpapir osv.<\/p>\n

Luftgennemtr\u00e6ngelighed:\u00a0<\/strong><\/p>\n

Luftgennemtr\u00e6ngelighed er den gennemsnitlige luftgennemstr\u00f8mning gennem en arealenhed under en trykforskel p\u00e5 en tidsenhed under bestemte forhold.<\/p>\n

Luftgennemtr\u00e6ngelighed udtrykkes i mikrometer pr. pascalsekund [1 \u03bcm\/(Pa-s)=1mL\/(m\u00b2-Pa-s)].<\/p>\n

2. Fordele ved TQD-01:<\/h2>\n

H\u00f8j opl\u00f8sning
\nBruger et klassisk spektrometerprincip
\nKan teste brandfarlige, giftige og eksplosive stoffer
\nHar et stort temperaturomr\u00e5de<\/p>\n

 <\/p>\n

3. Princip<\/h2>\n

Fastsp\u00e6nding af et pr\u00f8veemne mellem to luftt\u00e6tte cirkul\u00e6re pakninger af kendte dimensioner, hvor det absolutte lufttryk p\u00e5 den ene side af pr\u00f8veemnets testomr\u00e5de svarer til atmosf\u00e6retrykket, og hvor trykforskellen mellem de to sider af pr\u00f8veemnet holdes p\u00e5 en lille, men i det v\u00e6sentlige konstant v\u00e6rdi under testen. Bestemmelse af luftstr\u00f8mmen gennem testomr\u00e5det i l\u00f8bet af en bestemt tid.<\/p>\n
