Abstract
The invention discloses a method for testing high-temperature tensile strength and high-temperature elongation percentage of a copper foil. The method is characterized by comprising the following steps of: firstly, cutting a sample: firstly, selecting a piece of copper foil sample without folds, drawing a marked line, cutting the sample by using a method of carving with a knife and avoiding waved sides, burrs and notches; secondly, clamping the sample: after the temperature of a high-temperature baking oven of a universal tester is raised to 180DEG C, opening a door of the baking oven and clamping the copper foil sample between an upper clamp and a lower clamp, keeping the sample perpendicular to a clamp plane, then starting the clamps to clamp the sample and closing the door of the baking oven; and thirdly, starting the universal tester for starting the test: starting timing after the temperature of the high-temperature baking oven is raised to 180DEG C and starting the universal tester for starting the test after 5 minutes. According to the method, the accuracy of the detected data reaches over 99 percent, so that the detection accuracy of physical property of a high-grade electrolytic copper foil is effectively ensured; and the detection time of the sample is saved and the detection cost is reduced.
Description
Technical field
The present invention relates to test the method for Copper Foil physical performance index, relate in particular to a kind of method of testing Copper Foil high temperature tensile strength and high temperature length growth rate.
Background technology
High temperature tensile strength, high temperature length growth rate be high-grade electrolytic copper foil physical property must survey index.The testing machine that is used to carry out the high temperature tension test of Copper Foil at present is a universal testing machine; Though it is very accurate; But also have some factors can directly influence the accuracy rate of high temperature tensile strength, high temperature length growth rate; Discover through our carefulness, tailor at sample, on the testing machine clamped sample, oven temperature control etc. several aspect, misoperation all can influence the accuracy rate of high temperature tensile strength, high temperature length growth rate.
Summary of the invention
The purpose of this invention is to provide a kind of method of testing Copper Foil high temperature tensile strength and high temperature length growth rate, can improve the accuracy rate of test high temperature tensile strength, high temperature length growth rate.
The present invention adopts following technical proposals: a kind of method of testing Copper Foil high temperature tensile strength and high temperature length growth rate; May further comprise the steps: (1), tailor sample: at first select a Copper Foil sample that does not have fold; Finish graticule earlier; Method with graduating with cutter is tailored sample, rippled edge and burr, breach can not occur; (2), clamped sample: after the temperature of universal testing machine high temperature oven is raised to 180 ℃, opens the baking oven chamber door Copper Foil specimen holder is held between the lower clamp, sample keeps vertical with the anchor clamps plane, starts the clamp clamps sample then, closes chamber door; (3), start universal testing machine and begin test: pick up counting after waiting the temperature of high temperature oven to be raised to 180 ℃, start universal testing machine after 5 minutes and begin test.
When tailoring sample with the method for graduating with cutter in the described step (1), the angle of cutting out between appearance cutter and the Copper Foil sample is spent less than 20.
After universal testing machine brings into operation, the Copper Foil sample is begun when stressed as the starting point of calculating pulling force and length growth rate in the said step (3).
The method that the present invention tests Copper Foil high temperature tensile strength and high temperature length growth rate begins test through tailoring sample, clamped sample, startup universal testing machine; More than the data rate of accuracy reached to 99% that detects; The rerum natura that has guaranteed high-grade electrolytic copper foil effectively detects accuracy rate; Not only practice thrift the detection time of sample, and reduced the detection cost.
Embodiment
The present invention tests the method for Copper Foil high temperature tensile strength and high temperature length growth rate; May further comprise the steps: (1), tailor sample: at first select a Copper Foil sample that does not have fold; Finish graticule earlier, tailor sample, rippled edge and burr, breach can not occur with the method for graduating with cutter; (2), clamped sample: after the temperature of universal testing machine high temperature oven is raised to 180 ℃; Opening the baking oven chamber door is clamped in the Copper Foil sample upward between the lower clamp fast; Sample keeps vertical with last lower clamp plane, starts the clamp clamps sample then, closes chamber door; Note wearing anti-high temperature gloves in the process of placement sample; (3), start universal testing machine and begin test: pick up counting after waiting the temperature of high temperature oven to be raised to 180 ℃, start universal testing machine after 5 minutes and begin test.The angle of cutting out between appearance cutter and the Copper Foil sample when wherein tailoring sample with the method for graduating with cutter in the step (1) is spent less than 20; Ruler will be by surely not sliding; Standardized cutter will get rid of a joint blade, and the dynamics of drawing can not be too big, particularly the Copper Foil below the 18 μ m; Conscientious especially when cutting out appearance, rippled edge and burr, breach can not appear.Wherein in the step (3) after universal testing machine brings into operation, the Copper Foil sample is begun when stressed as the starting point of calculating pulling force and length growth rate.Through test of many times; The above-mentioned test in process of the test; More than the data rate of accuracy reached to 99% that detects, guaranteed that effectively the rerum natura of high-grade electrolytic copper foil detects accuracy rate, the detection time of not only having practiced thrift sample; And having reduced the detection cost, this detection method can be promoted the use of at Copper Foil and similar industry product context of detection.
