Description
Technical field
The utility model relates to a kind of device of test material permeability rate, is specifically related to the permeability rate proving installation of materials such as a kind of organic luminescent device film, waterproof roll, beverage and packaging for foodstuff.
Background technology
ORGANIC ELECTROLUMINESCENCE DISPLAYS is compared with other forms of demonstration, has an important advantage can realize flexible demonstration exactly, and a fatal weakness---device lost efficacy easily, and the life-span is shorter but it also exists.Great deal of research results show the negative electrode active metal easily with the steam generation oxidation reaction that gets into, at negative electrode and organic functions interlayer formation insulation course, cause the device can't be luminous; And the existence of water can be brought out the electrolysis venting that electrochemical reaction and water take place between ito anode and the metal electrode, formation blackspot; Even more serious is that irreversible chemical reaction takes place for organic material meeting itself and steam, destroys the structure of organic molecule and polymkeric substance, reduces its luminescence efficiency, causes component failure.Therefore for flexible organic luminescent device, make membraneous material, at first must solution how measure the permeability rate problem of material with high resistant water-based.In addition, in other fields such as beverage/food packing, waterproof rolls, also need a kind of simple and efficient permeability rate pick-up unit.
The method of present test material permeability rate mainly contains calcium erosion test resistance method of changing and (sees R. Paetzold and A. Winnacker; Rev. Sci. Instrum.; Vol. 74, No. 12, and December 2003) and test gas permeability rate equal-pressure method relatively more commonly used etc.Calcium erosion test resistance method of changing is that the calcium film is sealed in institute's material film of measuring and monitoring the growth of standing timber is inner; Because calcium is prone to cause resistance to raise with the steam reaction; Change the steam transmitance that can calculate material film through test calcium film resistance; Cause sheet resistance to raise merely but this method often makes the generation galvanic corrosion of calcium film easily, make the result of calculation generation than mistake with the steam reaction, and complicated operation.And equal-pressure method is to utilize sample will permeate the chamber to be divided into two independently air flow systems, the test gas of a side for flowing, the dry carrier gas (nitrogen) of opposite side for flowing.The pressure on sample both sides equates (standard is 0.1MPa); But the steam dividing potential drop is different, and under the partial pressure difference effect of steam, steam sees through film and delivered in the sensor by nitrogen stream; Accurately measure the vapour quantity that carries in the nitrogen stream by sensor, thereby calculate the steam transmitance of material.Owing in the equal-pressure method test philosophy, the needs of carrier gas are made and have two kinds of gases that quantity is suitable in the method; When the sample both sides have 0.1MPa steam partial pressure difference to exist; Also there is 0.1MPa nitrogen partial pressure difference to exist; The existence of nitrogen makes steam all can be interfered for the whole process of osmosis of sample, and test the time need consume a large amount of carrier gas.
