Metoden \u00e4r till\u00e4mplig p\u00e5 papper och br\u00e4dor som har luftpermeanser mellan1 \u00d7 10-2 ~ 1 \u00d7 10\u00b2um \/ \uff08Pa.S\uff09. Metoden \u00e4r ol\u00e4mplig f\u00f6r papper och kartong med grov yta, t.ex. kr\u00e4ppade och korrugerade papper, som inte kan kl\u00e4mmas fast ordentligt f\u00f6r att undvika l\u00e4ckage.<\/p>\n

TQD-01 Luftgenomsl\u00e4pplighetsm\u00e4tare<\/strong>\u00a0kan \u00e4ven anv\u00e4ndas f\u00f6r andra material som t.ex. cementpappersp\u00e5se, pappersp\u00e5sepapper, kabelpapper, kopieringspapper, industriellt filterpapper etc.<\/p>\n

Luftgenomsl\u00e4pplighet:\u00a0<\/strong><\/p>\n

Luftgenomsl\u00e4pplighet \u00e4r det genomsnittliga luftfl\u00f6det genom en areaenhet under en tryckskillnad och en tidsenhet, under angivna f\u00f6rh\u00e5llanden.<\/p>\n

Luftgenomsl\u00e4ppligheten uttrycks i mikrometer per pascalsekund [1 \u03bcm\/(Pa-s)=1mL\/(m\u00b2-Pa-s)].<\/p>\n

H\u00f6g uppl\u00f6sning
\nAnv\u00e4nder en klassisk spektrometerprincip
\nKan testa brandfarliga, giftiga och explosiva \u00e4mnen

 <\/p>\n

3. Princip<\/h2>\n

Fastsp\u00e4nning av en provkropp mellan tv\u00e5 luftt\u00e4ta cirkul\u00e4ra packningar av k\u00e4nda dimensioner, varvid det absoluta lufttrycket p\u00e5 ena sidan av provkroppens provomr\u00e5de motsvarar atmosf\u00e4rstrycket och tryckskillnaden mellan provkroppens b\u00e5da sidor h\u00e5lls p\u00e5 ett litet men i stort sett konstant v\u00e4rde under provningen. Best\u00e4mning av luftfl\u00f6det genom provomr\u00e5det under en best\u00e4md tid.<\/p>\n
