1. Prezentarea testerului de permeabilitate la aer TQD-01<\/h2>\n

TQD-01 Tester de permeabilitate a aerului<\/strong>\u00a0este utilizat pentru a determina permeabilitatea la aer a h\u00e2rtiei \u0219i cartonului \u00een intervalul mediu de permeabilitate la aer, utiliz\u00e2nd metoda Schopper.<\/p>\n

Metoda se aplic\u0103 h\u00e2rtiilor \u0219i pl\u0103cilor care au permeabilit\u0103\u021bi la aer cuprinse \u00eentre1\u00d710-2~1\u00d710\u00b2um\/\uff08Pa.S\uff09. Metoda nu este adecvat\u0103 pentru h\u00e2rtiile \u0219i pl\u0103cile cu suprafa\u021b\u0103 rugoas\u0103, cum ar fi h\u00e2rtiile creponate \u0219i ondulate, care nu pot fi fixate \u00een siguran\u021b\u0103 pentru a evita scurgerile.<\/p>\n

TQD-01 Tester de permeabilitate a aerului<\/strong>\u00a0poate fi utilizat \u0219i pentru alte materiale, cum ar fi h\u00e2rtia pentru saci de ciment, h\u00e2rtia pentru saci de h\u00e2rtie, h\u00e2rtia pentru cabluri, h\u00e2rtia pentru copii, h\u00e2rtia pentru filtre industriale etc.<\/p>\n

Permeabilitatea la aer:\u00a0<\/strong><\/p>\n

Permeabilitatea aerului este debitul mediu de aer prin unitatea de suprafa\u021b\u0103 sub unitatea de diferen\u021b\u0103 de presiune \u00een unitatea de timp, \u00een condi\u021bii specificate.<\/p>\n

Permeabilitatea aerului este exprimat\u0103 \u00een micrometri pe secund\u0103 pascal [1 \u03bcm\/(Pa-s)=1mL\/(m\u00b2-Pa-s)].<\/p>\n

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

Rezolu\u021bie \u00eenalt\u0103
\nFolose\u0219te un principiu clasic de spectrometru
\nPoate testa substan\u021be inflamabile, toxice \u0219i explozive
\nAre o gam\u0103 larg\u0103 de temperaturi<\/p>\n

 <\/p>\n

3. Principiul<\/h2>\n

Fixarea unei eprubete \u00eentre dou\u0103 garnituri circulare etan\u0219e de dimensiuni cunoscute, presiunea absolut\u0103 a aerului de pe o parte a zonei de \u00eencercare a epruvetei fiind echivalent\u0103 cu presiunea atmosferic\u0103, iar diferen\u021ba de presiune dintre cele dou\u0103 p\u0103r\u021bi ale epruvetei fiind men\u021binut\u0103 la o valoare mic\u0103, dar practic constant\u0103 \u00een timpul \u00eencerc\u0103rii. Determinarea debitului de aer prin zona de testare \u00eentr-un timp specificat.<\/p>\n
