た状態で通気度を求めることができなかった。The conventional 1-cloth ventilation variation test method is to test Fi-cloth by using a 7-radial type tester, and in the case of a 9-filter cloth with a paddle filter dust collector flK set, the melting conditions change, making it difficult to use in practical use. It is not possible to know the degree of ventilation accurately. In other words, the measurement results with the Frazier type tester and the case where it is used in a 3A field are 1
The tension of the cloth varies greatly. Furthermore, it was not possible to determine the air permeability in a state where dust was actually attached.

装瞳用濾布の通気度試験方法。Attach a suction cup to the filter cloth to be measured! Then, when the cloth surface is suctioned by the Makoto pump, the pressure is measured by the pressure gauge, and the vacuum opening is adjusted by operating the valve of the vacuum pump. Measure the flow rate 1-1 Divide the suction flow rate by the area of the suction cup,
A method for testing the air permeability of a filter cloth for a filtration collector and pupil, which is characterized by obtaining air permeability per unit area.

In the figure, 1 is a dust-collecting filter cloth that allows air to flow from the inside to the outside to cause dust a to adhere thereto. = A suction cup is placed in close contact with the filter cloth 1 of the pigeon, and a backing 3 is used to keep the adhesive surface airtight as shown in Figure 2, but in addition, a needle 4 is attached to the adhesive surface of the glue-like adhesive resin as shown in Figure W2B. May be planted. The suction cup FU communicates with the vacuum pump SK via pipe 5, and
It communicates with a pressure gauge 8 through another pipe 7, and also with a vacuum pump 6.
It communicates with a flow meter 101c via a pipe 9.

れる。With the suction cup 2 in close contact with the filter cloth 1, the vacuum pump 6
The vacuum level is controlled by activating and suctioning, measuring the pressure with the pressure gauge 8, that is, the pressure loss of the filter cloth, and operating the valve 11 of the vacuum pump 6.
By keeping the suction pressure constant, the appropriate air permeability (aeration amount) can be obtained.
