Description
Technical field
The present invention relates to technical field of photovoltaic power generation, the test method of specifically a kind of photovoltaic module POE glue film degree of cross linking.
Background technique
Currently, glue film cuts into 2mm or so after being that will be laminated in the main method of the photovoltaic industry measurement glue film degree of cross linking, put
Enter into steel wire mesh bag, reflux extraction is carried out in 140 DEG C or so of boiling xylene.It needs to cut sample during the test
Product, production mesh bag operation is comparatively laborious, also has small crosslinking powder in reflux course and spills on the outside of mesh bag, causes test inclined
Difference.In test reflux course, for control back-flow velocity and liquid long-time heating gas bumping spilling is avoided to lead to dangerous need
Personnel are wanted to be monitored test, reflux course condensation is also required to cause the waste of water resource using a large amount of tap water.
Temperature is higher when additionally, due to xylene solution boiling, close with the voltage-controlled temperature processed of adhesive film, high herein for a long time
Under temperature state, secondary cross-linking can occur because of high temperature for uncrosslinked part in sample, influence the accuracy of test result.
Summary of the invention
The purpose of the present invention is to provide a kind of test method of photovoltaic module POE glue film degree of cross linking, the work of this method
Temperature is lower than solvent boiling point temperature, and test is easy to control, is safe, and resource consumption is few, easy to operate, improves the accurate of test result
Property.
The technical solution adopted by the present invention to solve the technical problems is:
A kind of test method of the photovoltaic module POE glue film degree of cross linking, comprising the following steps:
S1, configuration xylene extraction solution；
S2, photovoltaic module POE glue film is cut as test sample, weigh test sample quality W1；
Test sample after S3, weighing is put into sample bottle, and xylene extraction solution, xylene extraction solution are added into sample bottle
With volume mass ratio >=60:1 of test sample；It is moved into drying box after sample bottle is sealed and carries out heating extraction, extraction temperature
It is set as 60~80 DEG C, extraction time is 5~8h；
After S4, extraction, test sample is taken out from sample bottle and is dried, test sample quality W2 extracted is weighed；
S5, the photovoltaic module POE glue film degree of cross linking is calculated according to formula D=W2/ W1 × 100%, D is the degree of cross linking in formula.
Further, when the step S4 dries test sample, test sample is placed on surface plate, then is put
Enter drying in vacuum drying oven, drying temperature is set as 140 DEG C, and vacuum degree >=0.08MPa, drying time is 2~5h.
The invention has the advantages that giving up traditional test method, in solvent boiling point temperature hereinafter, using chemical extraction
Method carries out the test of the photovoltaic module POE glue film degree of cross linking；Degree of cross linking test temperature is changed to low temperature by the boiling temperature of dimethylbenzene
Test, avoids secondary cross-linking from influencing；Low-temperature test will no longer be required to paraxylene liquid and flow back, therefore not need using arriving
Condensed water and corresponding reflux unit；Simplify testing process simultaneously, saves the time.
Specific embodiment

S1, configuration xylene extraction solution, xylene extraction solution are that antioxidant configuration is added in analytically pure dimethylbenzene
Solution；
S2, photovoltaic module POE glue film is cut as test sample, weigh test sample quality W1；When specific operation, it can cut
The POE glue film long * wide about 5*5cm of 0.5mm thickness obtains the test sample of 1g or so, then accurately claims to the quality of test sample
Amount；
Test sample after S3, weighing is put into sample bottle, and xylene extraction solution, xylene extraction solution are added into sample bottle
With volume mass ratio >=60:1 of test sample；
With two groups of data instances:
As test sample quality W1=1g, 60ml xylene extraction solution is added into sample bottle；
Or as test sample quality W1=1g, 80ml xylene extraction solution is added into sample bottle；
It is moved into drying box after sample bottle is sealed and carries out heating extraction, extraction temperature is set as 60~80 DEG C, extraction time 5
~8h；
After S4, extraction, sample bottle taking-up is cooled to room temperature, test sample taking-up is then placed on surface plate with tweezers
On, drying in vacuum drying oven is placed into, drying temperature is set as 140 DEG C, and vacuum degree >=0.08MPa, drying time is 2~5h；
Weigh test sample quality W2 extracted, unit g；
S5, the photovoltaic module POE glue film degree of cross linking is calculated according to formula D=W2/ W1 × 100%, D is the degree of cross linking in formula.
Xylene extraction solution after test can be recycled, and reuse after being purified using distilling apparatus.
The temperature when present invention extracts subtracts well below the solvent boiling point temperature of conventional method there is no need to flow back
