Description
Technical field
The utility model relates to a kind of instrument that the degree of cross linking detects that is used for, and specifically is meant the EVA particle shear in the degree of cross linking detection.
Background technology
The degree of cross linking is claimed cross-linking index again; Be used to characterize the crosslinking degree of macromolecular chain; Usually represent with the number-average molecular weight between crosslink density or two the adjacent crosslinking points or the molal quantity of every cubic centimetre of crosslinking points, can record the degree of cross linking than method with mechanics method or equilibrium swelling; The caoutchouc elasticity that the degree of cross linking is little is better, and the caoutchouc elasticity that the degree of cross linking is big is poor, and the degree of cross linking increases again, and mechanical strength and hardness all will increase, and finally follow the string.Along with the continuous development of photovoltaic new energy field, various corollary equipments are also in constantly innovation and renewal in the industry.And in Crystalline Silicon PV Module is produced the detection components degree of cross linking step that is absolutely necessary; Assembly production is to be based upon on the qualified basis of the assembly degree of cross linking to carry out, so guarantee that in industry the accuracy of degree of cross linking experiment is very important.But even to this day, on degree of cross linking 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 degree of cross linking sample generally is to adopt artificial preparation method: at first, use small size safety 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 degree of cross linking 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.
