LR-F012聽 聽Air Permeability Test Machine For Paper working principle聽

By using the principle of differential pressure method, the pre-processed sample is placed between the upper and lower measuring surfaces and a constant differential pressure is formed on both sides of the sample. Under the action of differential pressure, gas flows through the sample from the high-pressure side to the low-pressure side. According to the area, differential pressure and flow rate of the sample, the permeability of the sample is calculated.
