Detailed Description
The following description is provided to assist the reader in obtaining a thorough understanding of the methods, apparatuses, and/or systems described herein. Accordingly, various changes, modifications and equivalents of the methods, devices and/or systems described herein will be apparent to those skilled in the art. Moreover, descriptions of well-known functions and constructions may be omitted to increase clarity and conciseness.
Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.
First, the configuration of an outdoor test apparatus for acceleration of exposure according to an embodiment of the present invention will be described below with reference to fig. 2 to 5.
An opening and closing door 20 formed to be openable and closable is provided near an open entrance of the case 10 in which the artificial light source lamp 80 is provided, a specimen mounting frame 21 is formed at a front surface of the opening and closing door 20 to mount the specimen 100 (a degradation state thereof is tested by sunlight exposure), the support frames 30 are coupled and supported at opposite sides of the opening and closing door 20 by the rotation shaft 41, and the driving motor 40 is mounted at any one of the support frames 30 to transmit a rotation force to the rotation shaft 41 by gear engagement.
Here, as shown in fig. 3, it is preferable that a first day Thermometer 22 and a second day Thermometer 23 are installed at positions adjacent to each other in the middle of the sample mounting frame 21 for independently measuring the amount of radiant energy in the entire radiant energy region (295 to 2500nm) and ultraviolet region (295 to 400nm), and a Black Panel Thermometer (BPT) 24 for measuring the surface temperature of the sample mounting frame 21 is installed thereunder.
Further, a plurality of opening and closing cylinders 50 for opening and closing the opening and closing door 20 are formed on opposite side walls of the housing 10, and a lower portion of the housing 10 is connected with a base pillar 70 via a hinge lever 71 and with an angle control cylinder 60 that controls a rotation angle of the housing 10.
Further, a drain hole 12 is formed at the bottom edge inside the case 10 for draining rainwater entering from the outside, and a plurality of blowers 90 are formed at the sidewall surface to forcibly circulate air to control the internal temperature.
Meanwhile, a detection sensor 15 for detecting a closed state of the opening and closing door 20 is formed at an entrance of the case 10, and protruding brackets 25a and 25b protrude from the opening and closing door 20 at positions corresponding to the detection sensor 15, and the two protruding brackets 25a and 25b are disposed at positions diagonally symmetrical to each other.
Various types of lamps may be used as the artificial light source lamp 80, and a metal halide lamp, which is made by adding a metal halogen compound to a mercury lamp to emit white light close to sunlight, is used in the present embodiment.
The effects of using the outdoor test equipment for acceleration of exposure of the embodiment of the present invention having the above-described configuration will be described below with reference to fig. 6 to 12.
First, in a state where the sample 100 subjected to the exposure test is fixed to the sample mounting frame 21, the housing 10 is controlled to have a certain angle using the angle control cylinder 60.
That is, since the sample-mounting frame 21 is exposed to the outside and the opening and closing door 20 is closed, the sample 100 mounted on the sample-mounting frame 21 is in a state of being exposed to the sunlight at this time as shown in fig. 6 and 7.
Meanwhile, the exposure test may be continued throughout the night using the artificial light source lamp 80 by placing the specimen mounting frame 21 on which the specimen 100 is mounted in the housing 10.
That is, as shown in fig. 8 to 11, the opening and closing door 20 is opened by the driving of the opening and closing cylinder 50 and spaced apart from the case 10 by a certain distance (fig. 8), the opening and closing door 20 is rotated by 180 ° about the rotation shaft 41 by the driving of the driving motor 40 (fig. 9), and the sample mounting frame 21 is positioned in the inside direction to correspond to the case 10 (fig. 10).
In the above state, when the opening and closing door 20 is returned to its original position and closed by the driving of the opening and closing cylinder 50, the detection sensor 15 simultaneously detects the closing and drives the artificial light source lamp 80 by contacting with the protruding brackets 25a and 25b, so that the sample 100 disposed at the sample mounting frame 21 can be continuously exposed to the ultraviolet light.
Further, during the driving of the artificial light source lamp 80, the internal temperature of the case 10 is controlled by the on/off control of the blower 90, and rainwater that may enter during the opening and closing of the opening and closing door 20 may be rapidly discharged through the drain hole 12.
Further, as the night time elapses and it is time set as the daytime in the control unit, the opening and closing door 20 is operated by the on/off drive and the rotational drive in the reverse manner to the above to expose the sample mounting frame 21 to the outside.
Therefore, the outdoor test equipment with accelerated exposure of the embodiment of the present invention allows the position of the specimen-mounting frame 21 to be changed according to the daytime and nighttime to realize continuous exposure tests.
Meanwhile, fig. 13 shows a cross-sectional configuration of a case 10 according to another embodiment of the present invention, in which a silver foil 11 is provided at an inner wall of the case 10 to internally reflect radiation emitted from an artificial light source lamp 80, a buffer pad 13 is formed at an inlet portion of the case 10 to absorb impact caused when the opening and closing door 20 is opened and closed, an elastic spring 14 is provided inside the buffer pad 13 to generate a double elastic force, and a mounting groove 16 is formed at one side of the case 10 such that one end portion of the elastic spring 14 is mounted thereto and supported.
With the above configuration, impact and vibration of the inlet portion of the case 10 are absorbed by the buffer pad 13 during the opening and closing operations of the opening and closing door 20, so that damage to the opening and closing door 20 and separation of the sample 100 from the sample-mounting frame 21 can be prevented.
In particular, the absorption effect against impact and vibration is further maximized due to the dual elastic function of the elastic spring 14 provided inside the cushion pad 13, and since the elastic spring 14 is stably supported by the mounting groove 16, it is possible to prevent the phenomenon that the elastic spring 14 is bent or deformed from occurring.
Further, due to the silver foil 11 provided on the inner wall of the housing 10, the radiation light emitted from the artificial light source lamp 80 can be reflected, so that an advantage of enhancing the exposure effect due to the diffused reflection of the ultraviolet light can be achieved.
The outdoor test equipment with accelerated exposure of the embodiment of the present invention described above can continuously perform degradation tests on polymer material samples not only during the day but also throughout the night, thereby having advantages of shortening the test period and achieving the effect of improving the reliability and reproducibility of the tests.
While certain specific embodiments have been described and illustrated, it will be apparent to those skilled in the art that various modifications can be made to the structure of the exposure accelerated outdoor test equipment of embodiments of the present invention.
However, such modified embodiments do not depart from the technical spirit or scope of the present invention and should be included within the scope of the present invention as defined in the appended claims.
Various embodiments have been described above. Nevertheless, it will be understood that various modifications may be made. For example, appropriate results may be achieved if the described techniques were performed in a different order and/or if components in a described system, architecture, device, or circuit were combined in a different manner and/or replaced or supplemented by other components or their equivalents. Accordingly, other implementations are within the scope of the following claims.
