ポリプロピレンなどをろ過材′とした高性能（ＨＥＩ）
Ａ ）フィルタが用いられている。Clean rooms and clean units are often used for work that requires a highly clean working atmosphere, such as in semiconductor manufacturing factories, nuclear power plants, medical facilities, etc. For this reason, high-performance (HEI) filters using glass fiber, polypropylene, etc. as filter media are used to remove airborne dust.
A) A filter is used.
これらのフィルタは従来、（イ）外観検査、（ロ）風量

。In particular, to check filter leakage and collection efficiency, polymer latex of known particle size is injected into the upstream side of the filter, and the upstream and downstream values are measured using a dust counter to determine the collection efficiency. The measurement points on the downstream side were run at equal intervals and the number of transmitted dust was measured to check for leaks.

できなかった。With these conventional filter evaluation methods, pinholes in the filter medium, poor adhesion between the filter medium and the outer frame, pinholes in the adhesive, etc., which are considered to be obvious initial defects, are treated as acceptable products as a result of cross evaluation. When removing suspended dust in the atmosphere that constantly contains moisture and water droplets,
No leakage due to deterioration of the adhesive between the filter material and the outer frame could be detected.

ルタの評価装置を提供することを目的としている。This invention places the high-performance filter to be evaluated on a support stand with its upstream side facing up, fills the top side with pure water, and checks for leakage of pure water droplets on the downstream side by storing it in a water meter.
In addition to being able to check the initial leakage of high-performance filters,
The purpose of the present invention is to provide an evaluation device for a high-performance filter for air purification, which makes it possible to confirm moisture resistance and water resistance by performing long-term evaluation for 10 to 20 hours.

いる。(4) is a support stand for the evaluation device, on which the filter (1) is placed with the upstream side through which air passes facing the top side. (5) is a saucer that is watertightly attached to the outer edge of the upper part of the support base (4) and has a funnel-shaped downward extension, and is made of a transparent synthetic resin sheet, such as a transparent vinyl chloride sheet, and has a water-repellent coating on the inner surface. It is alms. (6) is fitted into the lower part of this saucer (5), and the saucer is a water meter that collects water from the tray (5) and measures the amount of water, and is made of, for example, a graduated cylinder. (7) is a timer, which is used to measure the elapsed time for the amount of water accumulated in the water meter (6). Note that a clock may be used instead of the timer (7) as the clock means. (8) is a pure water supply pipe to which a cock (9) is connected to supply pure water αO.

する水の状態を目視することにより判定できる。In the apparatus of the above embodiment, the high-performance filter (1) to be evaluated is placed on the support stand (4) with the upstream side through which air permeates facing upward, and pure water Q (j) is placed on the top surface of the filter (1). If there is an initial failure of the filter (1), it can be determined by visually observing the initial amount of water accumulated in the water meter (6) or the condition of the water flowing down the saucer (5).

い。To check for leakage and to check the collection effect of the filter (1), a polymer latex permeation test is carried out in the same manner as in the conventional case described above. After this, a test is carried out for about 10 to 20 hours using the above-mentioned evaluation device, and the filter (1) is confirmed to have no leakage, and the filled pure water is gently discharged (failure to do so will result in damage to the filter material). After drying, if the product passes the polymer latex permeation test again and is shipped as a finished product, it can be determined that the initial failure of the high-performance filter and the moisture and water resistance evaluation have been checked.Moisture resistance and water resistance As for the sexual lifespan, 20 hours is sufficient as a guideline.

短時間に評価できる効果がある。As described above, according to the present invention, a high-performance filter to be evaluated is placed on a support stand with its upstream side facing upward, the top surface of the filter is filled with pure water, and a tray is provided below the downstream side. The quality of the purified pure water is measured with a water meter, and changes in the amount of accumulated water over time can be investigated using a time-opening method, making it possible to check for initial failure of the filter, as well as moisture resistance and water resistance evaluation, which is much easier than conventional methods. This has the effect of allowing evaluation items that could not be evaluated to be evaluated easily and in a short time.
