Description
Technical field
The present invention relates to a kind of instrument that degree of crosslinking detects that is used for, specifically be meant to be used for the EVA sample strip stripping off device that degree of crosslinking detects.
Background technology
Degree of crosslinking is claimed crosslinking index again; Be used to characterize the crosslinking degree of macromolecular chain; Usually represent with the number-average molecular weight between cross-linking density or two the adjacent crosslinking points or the molal quantity of every cubic centimetre of crosslinking points, can record degree of crosslinking than method with mechanics method or equilibrium swelling; The caoutchouc elasticity that degree of crosslinking is little is better, and the caoutchouc elasticity that degree of crosslinking is big is poor, and degree of crosslinking increases again, and physical strength and hardness all will increase, and finally follow the string.Along with the continuous development of photovoltaic new energy field, various support equipments are also in constantly innovation and renewal in the industry.And in Crystalline Silicon PV Module is produced the detection components degree of crosslinking step that is absolutely necessary; Assembly production is to be based upon on the qualified basis of assembly degree of crosslinking to carry out, so guarantee that in industry the accuracy of degree of crosslinking experiment is very important.But even to this day, on degree of crosslinking sample sampling link, also there is not its pairing sampling equipment to satisfy requirement of experiment.
At current line in the industry, the method for producing the degree of crosslinking sample generally is to adopt artificial preparation method: at first, use small size tempered glass to make experiment package training sheet; Then, treat that the compacting of experiment training sheet is accomplished after, on training sheet chosen position, use cutter to draw the zone of getting 10mm * 30mm by manual work, use tweezers that EVA is separated with backboard; At last, be the granule of 2mm * 2mm with the EVA that takes off through artificial clip, guarantee that the size of particle meets size expense tool to the EVA particle sizing, choose satisfactory EVA particle.
Above method still exists some shortcomings and difficult point: 1 draws the sample strip of getting on experiment training sheet generally is to use tonger under drawing on glass; Sample strip is the adherend of EVA and backboard, and simultaneously EVA and glass also are coherent, and need EVA and glass be separated is need very big strength at present; General no matter be the combination of which kind of material; The peel strength of glass and EVA all slightly is better than the peel strength of backboard and EVA, and the value of these two kinds of peel strengths is between 150N/10mm-200 N/10mm, and EVA can produce deformation when choosing sample strip; EVA and backboard have a tangible range difference; This time, deformation took place in EVA, and this part the deformation EVA that gets off of choosing is drawn thinly on the basis of original thickness, and deformation EVA can not be used for the degree of crosslinking experiment; That is: operating personnel's effort in the sampling process uses cutter and tonger dangerous; Sample strip after the sampling can not be utilized fully; The laboratory sample EVA that stands after the mechanical stress effect possibly influence experimental result.After 2 EVA laboratory sample bars took off, when making the EVA particle, the method for artificial preparation was under the situation of personnel's range estimation, to use scissor cut to go out the laboratory sample particle of particle size at 2 ± 0.5mm * 2 ± 0.5mm; But particle size is wayward, if it is big to use measurer to measure the screening workload, and the waste experiment material, cause man power and material's waste.
Summary of the invention
The objective of the invention is to overcome that sample strip is difficult to join the problem that sheet is pulled up from glass in the problems referred to above, a kind of EVA sample strip stripping off device that degree of crosslinking detects that is used for is provided, reduce in the sampling process operating personnel and require great effort and use the danger of cutter and tonger existence; Improve the sample strip utilization factor after taking a sample; The laboratory sample bar of avoiding standing after the mechanical stress effect influences experimental result.
The object of the invention is realized through following technical proposals:
