Abstract
The invention discloses an ethylene-vinyl acetate (EVA) particle shearing device for cross-linking degree detection. The EVA particle shearing device comprises a shell. The interior of the shell has a cavity structure, and the bottom of the shell is open. A cutting plate is arranged at the bottom of the shell. Cutting grids raised from the cutting plate are arranged on the cutting plate, and formed by cutters. A through hole is formed in the cutting plate in each cutting grid. An ejector structure is arranged in the cavity of the shell. Compared with the conventional device adopting a manual shearing mode, the EVA particle shearing device has the advantages that EVA particles can be uniform, and a screening process is not required, so that the preparation difficulty and workload of the EVA particles are reduced; and the EVA particle shearing device is simple in structure and convenient to use, and can be used as a manual tool as well as an automatic tool, and only a necessary transmission structure and a necessary controller are required to be added.
Description
Technical field
The present invention relates to a kind of instrument detecting for the degree of cross linking, specifically refer to the EVA particle shear in degree of cross linking detection.
Background technology
The degree of cross linking claims again cross-linking index, for characterizing the crosslinking degree of macromolecular chain, conventionally represent by the number-average molecular weight between crosslink density or two adjacent crosslinking points or the molal quantity of every cubic centimetre of crosslinking points, can record the degree of cross linking than method by 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 large 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 development of photovoltaic new energy field, in industry, various corollary equipments are also in constantly innovation and renewal.And in Crystalline Silicon PV Module is produced the detection components degree of cross linking step that is absolutely necessary; It is to be based upon on the basis that the assembly degree of cross linking is qualified to carry out that assembly is produced, so guarantee that the accuracy of degree of cross linking experiment is very important in industry.But even to this day, in degree of cross linking sample sampling link, also do not have its corresponding sampling equipment to meet requirement of experiment.
At current line in the industry, the method for producing degree of cross linking sample is generally to adopt artificial preparation method: first, use small size safety glass to make experiment package training sheet; Then,, after experiment training sheet suppress, by the region that manually uses cutter to draw in training sheet chosen position to get 10mm × 30mm, use tweezers separate EVA with backboard; Finally, the granule that is 2mm × 2mm by artificial clip by the EVA taking off, ensures that the size of particle meets size expense tool to EVA particle sizing, chooses satisfactory EVA particle.
Above method still exists some shortcomings and difficult point: 1 on experiment training sheet, to draw the sample strip of getting be generally to use tonger under drawing on glass, sample strip is the adherend of EVA and backboard, and while EVA and glass are also coherent, now need by EVA and glass separate be need to be very large strength, general no matter be the combination of which kind of material, the peel strength of glass and EVA is all slightly 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, in the time choosing sample strip, EVA can produce deformation, EVA and backboard have an obvious range difference, there is deformation in EVA this time, and this part the deformation EVA getting off that chooses is that quilt is drawn thin on the basis of original thickness, deformation EVA can not be used for degree of cross linking experiment, that is: operating personnel's effort in sampling process, use cutter and tonger dangerous, sample strip after sampling can not be utilized completely, the laboratory sample EVA standing after mechanical stress effect may affect experimental result.After 2 EVA laboratory sample bars take off, in the time making EVA particle, the method for artificial preparation is in the situation that personnel estimate, 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 large to use measurer to measure screening workload, and waste experiment material, cause man power and material's waste.
Summary of the invention
