Abstract
The invention relates to a permeability tester, specifically to an apparatus used for testing permeability of a polymer film material. The permeability tester mainly comprises a top cover (1) and a hot water tank (4), wherein a humidity sensor (2) is arranged in the top cover (1), a heating sleeve (6) is arranged at the periphery of the hot water tank (4), and a to-be-tested object (3) is placed between the top cover (1) and the hot water tank (4). Water (5) in the hot water tank (4) is heated, and vaporized water penetrates the to-be-tested object (3) and reaches the interior of the top cover (1); then the humidity sensor (2) in the top cover (1) sends a humidity signal to a humidity display instrument (7), and a tester can know water vapor permeability of the to-be-tested object through the number of degrees of the display instrument. The permeability tester provided by the invention has a simple structure, is convenient to operate, can rapidly test the water vapor permeability of a polymer film material at certain temperature and humidity and provides important experimental data for material analysis and testing.
Description
Technical field
The present invention relates to a kind of permeability rate tester, be specifically related to a kind of polymer thin-film material permeability rate tester, belong to field of measuring technique.
Background technology
Why the life-span of photovoltaic module use at present can reach more than 20 years, and key is that backboard has used the better weather material.Mainly be subjected to temperature, humidity, the influence of factors such as ultraviolet ray in the process that assembly uses out of doors, wherein bigger with humidity effect, in order to improve the ability of assembly opposing moisture attacks, must improve the anti-water permeability of back veneer material, at present, a lot of assembly material commercial cities are developed the material with high water resistant rate one after another, such as PVF, PVDF, PPE etc., assembly manufacturer must carry out long-term check in batches to these materials, could satisfy the requirement of assembly production and use.At present, have part permeability rate tester selling on the home market, but expensive, use cost is higher, is unfavorable for that enterprise uses on a large scale, is unfavorable for that especially dispatching from the factory of backboard detected and the supplied materials of assembly factory detects.
Summary of the invention
Problem at above-mentioned prior art exists the invention provides the cheap permeability rate tester of a kind of easy operation, and this tester can be used for the test of the permeability rate of polymer thin-film material.
For achieving the above object, the technical solution adopted in the present invention is: mainly comprise two part compositions of top cover and hot water storgae, wherein top cover is circular, a humidity sensor has been installed in inside, this sensor other end connects the humidity display instrument, and the outside heating jacket that coats of hot water storgae is equipped with water in the groove, water temperature control is at 40 ℃～90 ℃, and top cover inside has three bolts to be used for connecting hot water storgae.
The invention has the beneficial effects as follows: simple in structure, easy to operate, cost is lower, can test out the permeability rate situation of polymkeric substance thin material under the temperature and humidity effect fast, for photovoltaic enterprise or other thin material industries provide a kind of detection means of permeability rate easily.
Description of drawings
Fig. 1 is a kind of structural representation of permeability rate tester;
Fig. 2 is the synoptic diagram of the top cover 1 of tester shown in Figure 1;
Among the figure: 1, top cover, 2, humidity sensor, 3, measured object, 4, heating tank, 5, water, 6, heating jacket, 7, the humidity display instrument, 8, bolt.
Embodiment
The present invention will be further described below in conjunction with accompanying drawing.
As shown in Figure 1 and Figure 2, a kind of permeability rate tester, mainly comprise 4 two part compositions of top cover 1 and hot water storgae, wherein top cover 1 is circular, and a humidity sensor 2 has been installed in inside, and these sensor 2 other ends connect humidity display instrument 7, the hot water storgae 4 outside heating jackets 6 that coat, water 5 is housed in the groove, and water temperature is controlled at 40 ℃～90 ℃, and top cover 1 inside has three bolts 8 to be used for connecting hot water storgae 4.
After making, measured object 3 is placed in the middle of top cover 1 and the hot water storgae 4, then bolt 8 is connected, tighten, connecting power supply heats to hot water storgae, experiment condition can carry out according to the standard of GB/T 16928 or ASTM D1653, perhaps set up on their own by the experimenter, after hot water storgae 4 heats a period of times, we can read the humidity in the top cover from the humidity display instrument 7, and then recognized the water-resisting ability of this material, the present invention is suitable for the water permeability test of polymer thin-film material, especially is suitable for use in the two or more membraneous material permeability rate property comparison experiments.
Claims (1)
1. permeability rate tester, mainly comprise top cover (1) and hot water storgae (4), it is characterized in that: top cover (1) is for circular, a humidity sensor (2) has been installed in inside, this sensor (2) other end connects humidity display instrument (7), and the outside heating jacket (6) that coats of hot water storgae (4) is equipped with water (5) in the groove, water temperature control is at 40 ℃～90 ℃, and top cover (1) inside has three bolts (8) to be used for being connected with hot water storgae (4).
