Product Feature

The machine changes the traditional water pressure test method, adopts the imported technology and uses the principle of pressure difference method. The pre-treated sample is placed between the upper and lower measuring surfaces, forming a constant pressure difference on both sides of the sample. Under the action of pressure difference, the gas flows from the high pressure side through the sample to the low pressure side, and calculates the permeability of the sample according to the area, pressure difference and flow rate flowing through the sample.

Standard

According to ISO 5636.1 “Paper determination of Air permeability of paper and board (medium standard paper)”, GB/T 458 “Determination of air permeability of paper and board”, QB/T 1667 “Paper and Board Breathability tester”, ISO2965 “Cigarette paper, forming paper, bonding paper and materials with discontinuous or directional breathability and strips with different breathability – Determination of breathability”, YC/T172 “Cigarette paper, forming paper, bonding paper and Materials with directional breathability”, GB/T12655 “Determination of breathability” Cigarette paper and other standards related requirements.
