非特許文献１に記載の耐候性試験装置において、キセノンアークランプが放射する光は、紫外線の割合に比して赤外線が多いため、太陽光の数倍の紫外線の照射とした場合は言うまでもなく、太陽光と同程度の紫外線の照射とした場合でも、試料の温度を下げにくい問題点がある。また、反射器を用いないため、直射光しか利用できず、照射強度を上げにくい問題点がある。
特許文献１に記載の耐候性試験装置において、メタルハライドランプは、定格電力の５０％から１００％で出力可変であるが、定格電力の６０％以下では不安定になり、照射強度を下げにくい問題点がある。

特許文献３に記載の耐候性試験装置において、試料の上面と紫外線放射用放電ランプの距離が２４０ｍｍ程度であるから、上下移動可能な試料載置台の可動範囲はせいぜい数ｃｍであり、照射強度の微調整しか出来ない問題点がある。 In the weather resistance test apparatus described in Non-Patent Document 1, since the light emitted by the xenon arc lamp is more infrared than the proportion of ultraviolet rays, it goes without saying that it is irradiated with ultraviolet rays several times that of sunlight. There is a problem that it is difficult to lower the temperature of the sample even when it is irradiated with ultraviolet rays equivalent to sunlight. Further, since no reflector is used, only direct light can be used, and there is a problem that it is difficult to increase the irradiation intensity.
In the weather resistance test apparatus described in Patent Document 1, the output of the metal halide lamp is variable from 50% to 100% of the rated power, but becomes unstable at 60% or less of the rated power and it is difficult to reduce the irradiation intensity. There is.
In the weather resistance test apparatus described in Patent Document 2, since the spray nozzle is fixed, when the sample mounting table is moved up and down, the positional relationship between the upper surface of the sample and the spray nozzle changes, and the water spraying condition changes. There is.
In the weather resistance test apparatus described in Patent Document 3, since the distance between the upper surface of the sample and the discharge lamp for ultraviolet radiation is about 240 mm, the movable range of the sample mounting table that can be moved up and down is at most several cm, and the irradiation intensity is There is a problem that only fine adjustment is possible.

以下、図に示す実施の形態により本発明をさらに詳細に説明する。なお、これにより本発明が限定されるものではない。   Hereinafter, the present invention will be described in more detail with reference to embodiments shown in the drawings. Note that the present invention is not limited thereby.

図１は、実施例１に係る耐候性試験装置１００を示す要部斜視図である。
この耐候性試験装置１００は、温度制御を行う試験槽１０と、光源室２０と、両者を区画するガラス板３０とを備えている。 FIG. 1 is a main part perspective view showing a weather resistance test apparatus 100 according to the first embodiment.
The weather resistance test apparatus 100 includes a test tank 10 that performs temperature control, a light source chamber 20, and a glass plate 30 that partitions both.

試験槽１０内には、案内バー１１と、案内バー１１に沿って２０ｃｍ以上移動可能に移動体１２を介して支持され試料Ｐ（例えば塗装した金属片）を保持する試料保持台１と、案内バー１１に沿って２０ｃｍ以上移動可能に移動体１３を介して支持され試料Ｐの表面に水を噴霧するスプレーノズル２とが設置されている。   In the test tank 10, there are a guide bar 11, a sample holder 1 that holds a sample P (for example, a coated metal piece) supported by a moving body 12 so as to be movable along the guide bar 11 by 20 cm or more, and a guide. A spray nozzle 2 that is supported via a moving body 13 so as to be movable along the bar 11 by 20 cm or more and sprays water on the surface of the sample P is installed.

光源室２０には、試料Ｐの表面に紫外線を含む光を照射するためのメタルハライドランプ３および反射器４が固設されている。   In the light source chamber 20, a metal halide lamp 3 and a reflector 4 for irradiating the surface of the sample P with light including ultraviolet rays are fixed.

図示しないが、メタルハライドランプ３は、不要な波長成分をカットするための波長カットフィルタを備えている。   Although not shown, the metal halide lamp 3 includes a wavelength cut filter for cutting unnecessary wavelength components.

移動体１２を移動させることにより、試料保持台１を移動させることが出来る。メタルハライドランプ３は固定であり、試料保持台１が移動すると、試料Ｐとの距離が例えば２０ｃｍ〜５５ｃｍに変わり、紫外線を含む光の照射強度を変えることが出来る。   The sample holder 1 can be moved by moving the moving body 12. The metal halide lamp 3 is fixed, and when the sample holder 1 moves, the distance from the sample P changes to, for example, 20 cm to 55 cm, and the irradiation intensity of light including ultraviolet rays can be changed.

他方、移動体１３を移動させることにより、試料保持台１の移動に合わせてスプレーノズル２を移動することが出来るため、試料Ｐとスプレーノズル２の相対位置を不変にでき、同一条件で水を噴霧することが出来る。   On the other hand, since the spray nozzle 2 can be moved in accordance with the movement of the sample holder 1 by moving the movable body 13, the relative position between the sample P and the spray nozzle 2 can be made unchanged, and water can be supplied under the same conditions. Can be sprayed.

（６）試料Ｐを取り出し、表面状態を顕微鏡や分光器などで観察する。 For example, the weather resistance test is performed as follows.
(1) The metal halide lamp 3 is operated at 70% or more of the rating.
(2) The sample holder 1 is moved, and the distance D is set so as to have a desired irradiation intensity (1 to 5 times the light intensity including ultraviolet rays of sunlight on the ground surface). Relationship between the distance D between the irradiation intensity is, for example, 3.5 mW / cm 2 at 9.8mW / cm 2, D = 35cm at 5.3mW / cm 2, D = 55cm at D = 20 cm.
(3) The spray nozzle 2 is moved in accordance with the movement of the sample holder 1.

(6) The sample P is taken out and the surface state is observed with a microscope or a spectroscope.

実施例１に係る耐候性試験装置１００によれば、試料Ｐの温度上昇を抑制でき且つ試料面への光の照射強度を安定に変更することができ且つ水の噴霧条件を同一に保つことが出来る。また、機械的強度の高い試料保持台１およびスプレーノズル２を移動し、メタルハライドランプ３を移動しないので、メタルハライドランプ３の割れやフィラメント切れなどを生じにくい利点がある。   According to the weather resistance test apparatus 100 according to the first embodiment, the temperature rise of the sample P can be suppressed, the light irradiation intensity on the sample surface can be changed stably, and the water spray conditions can be kept the same. I can do it. Further, since the sample holder 1 and the spray nozzle 2 having high mechanical strength are moved and the metal halide lamp 3 is not moved, there is an advantage that the metal halide lamp 3 is not easily cracked or broken.
