The air permeability tester yakagadzirirwa uye kugadzirwa kwesement bag bepa, pepa bhegi pepa, tambo pepa, kopi bepa uye indasitiri sefa pepa, nezvimwewo, kuyera saizi yemhepo yaro permeability, chiridzwa chakakodzera mhepo kupera pakati pe1 × 10-2 ~ 1 × 102um/ (pa.s), kwete yebepa rine hombe rough.
Ndiko kuti, pasi pemamiriro akatarwa, nguva yeyuniti uye unit pressure difference, unit area of paper through the average air flow. Mazhinji marudzi emapepa, senge simende bhegi bepa, pepa bhegi bepa, tambo bepa, kopi bepa uye maindasitiri sefa bepa, inoda kuyera permeability yayo, chiridzwa ichi chakagadzirwa uye chakagadzirirwa marudzi ese emapepa. Ichi chiridzwa chakakodzera mhepo permeability pakati 1 × 10-2 ~ 1 × 102um / (pa. S), haina kukodzera pamusoro pepamusoro pepepa rakakura rakaoma.
Iyo mita yekufema inopindirana neQB/T1667-98 "Pepa uye kadhibhodhi breathability Tester", GB/T458-1989 "Pepa uye kadhibhodhi breathability determination Method" (Schobol). Iso1924/2-1985 QB/T1670-92 uye mamwe maitiro akakodzera.
