Description
本考案は、耐候光試験機に関する。更に詳しくは、試料の劣化を調べる耐候光試験機に関するものである。 The present invention relates to a weathering light testing machine. More specifically, the present invention relates to a weathering light tester for examining deterioration of a sample.
従来の耐候光試験機では、外気を取り入れて試験槽下部の送風機により試験槽内に送り込んで試験槽内の温度調節を行っていた（例えば、特許文献１参照）。
情報記録紙の耐候光試験機をするにあたって、色の退色を調べるため、三原色、例えば、シアン、マゼンタ、イエローを単独に紙に印刷して調べることがある。 In order to check the color fading when using a weatherproof light testing machine for information recording paper, there are cases where three primary colors, for example, cyan, magenta, and yellow are individually printed on paper and checked.
シアン、マゼンタ、イエローのうち、シアンはオゾンに弱く、外気中の微量なオゾンにおいても退色してしまう。 Of cyan, magenta, and yellow, cyan is weak to ozone, and even faint ozone in the outside air will fade.
しかし、従来の耐候光試験機では、ごみ取り用のフィルタを取付けて外気を取り入れているため、取り入れた外気中にオゾンやＳＯ２やＮＯ２などのガスが含まれる。このため、シアンの退色試験等、すなわちオゾン等による退色がある材料に対する試験で得られた結果が、外気のオゾンの影響か、人工光源の光による影響か分からないことがあり、判定に苦慮することがあった。 However, in a conventional weathering light tester, a filter for removing dust is attached and the outside air is taken in. Therefore, gases such as ozone, SO 2 and NO 2 are included in the taken outside air. For this reason, it may be difficult to determine whether the result obtained in a cyan fading test, i.e., a test on a material with fading due to ozone or the like, is influenced by ozone from the outside air or light from an artificial light source. There was a thing.
本考案が解決しようとする問題点は、オゾン、ＳＯ２、ＮＯ２などのガスの影響を受けやすい材料の試験において、オゾン、ＳＯ２、ＮＯ２などのガスの影響で退色したのか、光によって退色したのか判定がしにくい点である。 Problem present invention is to provide ozone, in the test of SO 2, NO 2 susceptible to gases, such as materials, ozone, whether faded by the influence of gas such as SO 2, NO 2, by light It is difficult to determine whether the color has faded.
本考案は、かかる問題を鑑みてなされたものであり、したがって、本考案の目的は、外気の影響を受けず、光による退色を正確に判定できる耐候光試験機を提供することにある。 This invention has been made in view of such problems, therefore, an object of the present invention are not influenced by the outside air, the photo-bleaching can be determined accurately and to provide a weather light tester.
上記目的を達成するために、本考案の耐候光試験機は、試験槽内に、人工光源を設けた耐候光試験機であって、外気取入口を設けた空気調節弁を開閉して試験槽内温度を調節する耐候光試験機において、空気調節弁の外気取入口に空気清浄フィルタ及び送風機を有するものである。 In order to achieve the above object, the weathering light tester of the present invention is a weathering light tester provided with an artificial light source in a test tank, which opens and closes an air control valve provided with an outside air intake. A weatherproof light tester for adjusting the internal temperature has an air purifying filter and a blower at the outside air intake port of the air control valve.
また、本考案の耐候光試験機は、試験槽内に、人工光源を設けた耐候光試験機であって、外気取入口を設けた空気調節弁を開閉して試験槽内温度を調節する耐候光試験機において、空気調節弁の外気取入口に空気清浄フィルタ及び送風機を有し、外気を挿入して室内温度を調節し、試験槽内の調節した温度条件を変化せず更に新しい空気を挿入することができる劣化装置であることを特徴とすることが好ましい。 Further, the weathering light tester of the present invention is a weathering light tester provided with an artificial light source in a test tank, and is a weatherproof light that adjusts the temperature in the test tank by opening and closing an air control valve provided with an outside air intake. The optical tester has an air purifier filter and a blower at the outside air inlet of the air control valve, inserts outside air to adjust the room temperature, and inserts new air without changing the adjusted temperature conditions in the test chamber. It is preferable that the apparatus is a deteriorating apparatus capable of performing the above.
試験槽内に、人工光源を設けた耐候光試験機であって、外気取入口を設けた空気調節弁を開閉して試験槽内温度を調節する耐候光試験機において、空気調節弁の外気取入口に空気清浄フィルタ及び送風機を有し、外気導入時に、外気取入口の送風機が、試験槽下部の送風機と同じ風量で送風するための風量制御手段を有することが好ましい。 The test chamber, a weathering light tester provided with artificial light sources, the weathering light tester for adjusting the opening and closing to test chamber temperature air regulating valve disposed outside air inlet, intake fresh air of the air regulating valve It is preferable to have an air purifying filter and a blower at the inlet, and when the outside air is introduced, the blower at the outside air intake has air volume control means for blowing with the same air volume as the blower at the lower part of the test tank.
本考案の耐候光試験機は、上述したとおりであるので、オゾンの影響を受けやすい材料の試験においても、外気の影響を受けず、光による退色を正確に判定できる。 Since the weathering light tester according to the present invention is as described above, even in a test of a material that is easily affected by ozone, it is possible to accurately determine fading due to light without being affected by outside air.
本考案の最良の実施例について、以下に図を用いて詳細に述べる。 The best embodiment of the present invention will be described below in detail with reference to the drawings.
図１は、本考案の耐候光試験機の実施例１の概略図である。 FIG. 1 is a schematic diagram of Example 1 of a weathering light tester according to the present invention.
図１に示した本考案の実施例１の耐候光試験機（１６）は、試験槽（１）、空気調節弁（５）を有する。試験槽（１）内に、人工の光源（６）を設けてある。空気調節弁（５）には試験槽内温度を調節するために、外気取入口（４）を設けてあり、空気調節弁（５）は開閉自在である。空気調節弁（５）の外気取入口（４）には空気清浄フィルタ（７）と送風機Ａ（２）を有する。また、試験槽（１）の下には、試験槽内空気を循環させる送風機Ｂ（３）を有する。 The weatherproof light testing machine (16) of Example 1 of the present invention shown in FIG. 1 has a test tank (1) and an air control valve (5). An artificial light source (6) is provided in the test tank (1). The air control valve (5) is provided with an outside air intake (4) for adjusting the temperature inside the test chamber, and the air control valve (5) can be opened and closed. The outside air inlet (4) of the air control valve (5) has an air cleaning filter (7) and a blower A (2). Moreover, it has the air blower B (3) which circulates the air in a test tank below a test tank (1).
本考案の実施例１の耐候光試験機（１６）は、外気導入時に、外気取入口（４）の送風機Ａ（２）が、試験槽下部の送風機Ｂ（３）と同じ風量で送風するための風量制御手段を有する。 In the weathering light test machine (16) of Example 1 of the present invention, when the outside air is introduced, the blower A (2) at the outside air inlet (4) blows with the same air volume as the blower B (3) at the bottom of the test tank. Air volume control means.
空気清浄フィルタ（７）には、たとえば、オゾンを除去したい場合は活性炭フィルタを用い、ＳＯ２やＮＯ２などのガスを除去したい場合は、そのガスを吸着又は化学反応させる触媒フィルタを用いる。 As the air purification filter (7), for example, an activated carbon filter is used to remove ozone, and a catalyst filter that adsorbs or chemically reacts with the gas is used to remove gases such as SO 2 and NO 2 .
試験槽内温度は、温度センサ（８）で試験槽内温度を感知し、温度調節器（９）の設定値と比較し、試験槽内温度を下げたいときは、空気調節弁（５）に調節弁を開く信号を送信して行う。当該信号に同期させて送風機Ａ（２）を作動させて空気調節弁（５）の外気取入口（４）より清浄な空気を送り込む。清浄な空気とは、オゾン、ＳＯ２、ＮＯ２などのガスを除去した空気をいう。 The temperature inside the test chamber is detected by the temperature sensor (8), and compared with the set value of the temperature controller (9). This is done by sending a signal to open the control valve. In synchronization with the signal, the blower A (2) is operated to feed clean air from the outside air inlet (4) of the air control valve (5). Clean air refers to air from which gases such as ozone, SO 2 and NO 2 have been removed.
送風機Ａ（２）は、試験槽内空気を循環させる送風機Ｂ（３）の風量と同じ風量に調整されている。送風機Ａ（２）は、フィルタを通過できるだけの静圧を有する。送風機Ａ（２）を空気清浄フィルタ（７）に取付け、試験槽内温度コントロール信号に同期させて、外気取入れが必要なときのみ送風機Ａ（２）を動作させ、清浄な空気を試験槽内に送り込む。 The air blower A (2) is adjusted to the same air volume as that of the air blower B (3) that circulates the air in the test tank. Blower A (2) has a static pressure sufficient to pass through the filter. A blower A (2) is attached to the air purification filter (7), synchronized with the temperature control signal in the test tank, and the blower A (2) is operated only when external air intake is necessary, and clean air is put into the test tank. Send it in.
本考案の耐候光試験機の実施例１では、送風機Ａ（２）によって、空気清浄フィルタ（７）による圧力損失を防止できる。 In Example 1 of the weathering light tester of the present invention, pressure loss due to the air cleaning filter (7) can be prevented by the blower A (2).
送風機Ａ（２）がないと、空気清浄フィルタ（７）によって、外気と試験槽内雰囲気との間に圧力差を生じることになる。この圧力差により、送風機Ｂ（３）を通して試験槽内に送られる風量が温度調節に必要な量より少なくなって、温度調節に時間がかかってしまう。 Without the blower A (2), the air purification filter (7) creates a pressure difference between the outside air and the atmosphere in the test chamber. Due to this pressure difference, the amount of air sent into the test tank through the blower B (3) becomes smaller than the amount necessary for temperature adjustment, and it takes time to adjust the temperature.
本考案の耐候光試験機の実施例１では、送風機Ａ（２）によって、送風機Ｂ（３）の風量と同じ風量の外気が空気清浄フィルタ（７）に吹き付けられるため、圧力損失が生じず、温度調節に必要な量の風を試験槽内に送り込むことができるので、温度調節が速やかにできる。 In Example 1 of the weathering light test machine of the present invention, since the outside air having the same air volume as that of the air blower B (3) is blown to the air cleaning filter (7) by the air blower A (2), no pressure loss occurs, Since the amount of wind necessary for temperature adjustment can be sent into the test chamber, the temperature can be adjusted quickly.
したがって、本考案の耐候光試験機の実施例１では、外気を挿入して室内温度を調節し、調節した室内温度条件を変化せず更に新しい空気を挿入することができる。 Thus, in Example 1 of weathering light tester of the present invention, it is possible to adjust the room temperature by inserting the outside air, to insert a newer air without changing the adjusted indoor temperature.
シアンについて従来方式の耐候光試験機と本考案の耐候光試験機の実施例１で比較試験をした結果を表１に示す。測定は、ＯＤ残存率とした。従来方式では、ＯＤ残存率の約３％分は、外気の影響であり、正確な試験ができていなかったことが判った。一方、の耐候光試験機の実施例１では、外気の影響がなく、正確な試験ができた。 Table 1 shows the results of comparative tests in Example 1 of a conventional type of weathering light tester and the present invention weathering light tester for cyan. The measurement was taken as the OD residual rate. In the conventional method, it was found that about 3% of the OD remaining rate was due to the influence of outside air, and an accurate test could not be performed. On the other hand, in Example 1 of the weathering light testing machine, there was no influence of outside air, and an accurate test was possible.
本考案の耐候光試験機の実施例１においては、外気の影響を受けず、光による退色を正確に判定できる。 In the first embodiment of the weathering light tester of the present invention, fading due to light can be accurately determined without being affected by outside air.
