Description
Technical field
The utility model belongs to light thermal property detection technique field, is specifically related to a kind of heat-proof quality pick-up unit.
Background technology
Thermal isolation film is to intercept heat in sunshine as much as possible as well, and in sunshine, heat is mainly distributed in visible ray and near infrared ray, and wherein, the wavelength coverage of visible ray is 380nm ~ 780nm, and near infrared wavelength coverage is 780nm ~ 2500nm.Visible ray can be seen by human eye, so be easy to judge obstruct situation, but infrared ray due to not see by human eye, be difficult to judge to intercept situation really, meanwhile, sunshine strength per unit area is less, is directly not easy obviously to be discovered by surplus heat difference after thermal isolation film.
Now commercially judge that the instrument of thermal isolation film heat-proof quality mainly contains solar film optical performance test instrument and infrared power meter etc., the type instrument response be the very narrow wave band of near-infrared region about 1400nm wavelength coverage, shared by each wave band, the ratio of solar heat is different, so the error of the test structure of the type instrument is larger.Wherein, the result better (namely the near infrared ray rejection rate of thermal isolation film is high) that thermal isolation film manufacturer tests on the type instrument in order to produced thermal isolation film, infrared absorbing agents is added in the glue-line of thermal isolation film, this infrared absorbing agents only absorbs the infrared ray of the wave band that the type testing tool responds, as only absorbed the infrared ray of about 1400nm wavelength coverage, so most thermal isolation film all shows as in the market, all fine by heat-proof quality during the analogous instrument tests such as solar film optical performance test instrument and infrared power meter, but actual heat-proof quality is very poor.This to cause on market not intercept infrared ray in a large number or only intercept the ultrared thermal isolation film of very small band exists and is difficult to again identify.
Utility model content
The purpose of this utility model solves the problem, and provides a kind of heat-proof quality pick-up unit being simply easy to operate.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of heat-proof quality pick-up unit, comprises light source and magnifier, and described magnifier is used for the light that focused light source produces, and described magnifier is placed in front or the rear of heat insulating member to be measured; Described heat insulating member to be measured is thermal isolation film to be measured or coated glass to be measured.
Preferably, described light source is the sun or infrared transmitter.
Preferably, when light source is the solar time, described magnifier comprises the eyeglass of visible ray in filtering sunshine.
Preferably, described eyeglass is colored lens.
Preferably, the pigment absorbing visible ray in sunshine is added with in described eyeglass; Or lens surface is provided with the coating or rete that absorb visible ray in sunshine.
Preferably, described pick-up unit also comprises temperature measuring device, for measuring the temperature of light after magnifier focuses on.
Preferably, described temperature measuring device is positioned at the focus place of magnifier.
Preferably, described heat intensity contrast difference realizes by barbecue article, skin feel or temperature measuring device.
The beneficial effects of the utility model are: the heat-proof quality pick-up unit that the utility model provides, utilizes the principle that magnifier focuses on, and make surplus heat difference amplify thus make it easily contrast, and can also obtain more accurate testing result by adopting temperature measuring device.Hinge structure easily causes heat-proof quality judge by accident thus make the defect that the heat insulating members such as thermal isolation film inferior flood market, the pick-up unit that the utility model provides is simple and testing result is accurate, can effectively promote the purification of the industries such as thermal isolation film and the lifting of product quality.
Accompanying drawing explanation
Fig. 1 is the utility model heat-proof quality structure of the detecting device schematic diagram.
Description of reference numerals: 1, magnifier; 2, heat insulating member; 3, temperature measuring device.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described further:
As shown in Figure 1, the utility model heat-proof quality structure of the detecting device schematic diagram, comprise light source, magnifier 1, heat insulating member 2 and temperature measuring device 3, the light that magnifier 1 produces for focused light source, temperature measuring device 3 is for the temperature of measuring magnifier 1 focal spot, heat insulating member 2 can be positioned over before magnifier 1 or below, with the order of light process for front and back, namely the light that light source produces can pass through heat insulating member 2 successively, magnifier 1 arrive again be arranged at magnifier 1 light spot position temperature measuring device 3 on, also can be that the light that light source produces can successively by magnifier 1, heat insulating member 2 arrive again be arranged at magnifier 1 light spot position temperature measuring device 3 on.The eyeglass of magnifier 1 can be transparent, translucent or coloured, the translucent eyeglass of preferred black, because the translucent eyeglass of black can filter out a large amount of visible rays in light source, through and focused IR line, the therefore preferred black lens magnifier 1 when judging high heat insulating member 2 heat-proof quality of visible light-transmissive.The color of colored lens can by adding pigment in eyeglass, on minute surface coating colour coating or paste the methods such as coloured rete to realize on minute surface, obviously, the method realizing eyeglass coloured is not limited thereto.Lens dimension there is no special regulation.Temperature measuring device 3 preferable temperature sensor.To the interpretation of heat-proof quality both by the temperature of direct measuring magnifier 1 focal spot of temperature measuring device 3, can also be judged by the intuitive manner of barbecue article, skin feel.Light source can be the sun or infrared transmitter.Heat insulating member 2 can be thermal isolation film or coated glass.
Principle and the process of the utility model heat-proof quality device is further illustrated below, to show advantage of the present utility model further with specific embodiment.
Embodiment 1
Cut-off footpath 10 ㎝ black translucent magnifier 1 focusing sunlight, focuses on leaf, and in time T1, leaf is burned and occur Jiao Dong.Before magnifier 1, place thermal isolation film, then by through solar light focusing to same leaf, roast same time T1, contrast leaf is placing the burned degree before and after thermal isolation film.Place the good thermal isolation film of heat-proof quality, the hot spot that magnifier 1 focuses on can not burned leaf, but the general thermal isolation film of heat-proof quality can burned leaf in various degree.Can proper extension time T1 with judge further thermal isolation film heat-proof quality quality.
