Embodiment

[0020] Such as figure 1 Shown, the present invention is used for the EVA sample strip peeling device of cross-linking degree detection, comprises base plate 1, and base plate 1 is rectangular as a whole, is installed with the column 2 opposite to each other on base plate 1, and column 2 is perpendicular to base plate 1, in two A guide rod 3 perpendicular to the column 2 is installed between the columns 2, and the guide rod 3 is parallel to the bottom plate 1. At the same time, a tool holder that can slide freely along the guide rod 3 is installed on the guide rod 3, and a sample peeling knife is installed on the tool holder. 4. The tops of the two columns 2 can be connected together to increase their tensile properties, or they can not be connected together, and the guide rod 3 can be used as a tie structure; below the guide rod 3, there is a platform 5 for placing the sheet. The bottom plate 1 is provided with two grooves 6 perpendicular to the column 2 and the guide rod 3 at...

Abstract

The invention discloses a stripping device for an EVA (Ethylene Vinyl Acetate) sample strip in the detection of crosslinking degree. The stripping device comprises a bottom plate, wherein two upright columns are mounted at the two sides of the bottom plate in parallel; a guide rod is mounted between the two upright columns; a sample stripping cutter capable of moving along the guide rod is mounted on the guide rod; a cultivation sheet placement platform capable of moving in a manner vertical to the guide rod is mounted on the bottom plate between the two upright columns; and the cultivation sheet placement platform is positioned between the sample stripping cutter and the bottom plate. Compared with the conventional stripping method, the stripping device does not adopt tools such as clamps, the safety is higher, and the danger caused by operating personnel using cutters and clamps in a labor-consuming way in the sampling process is reduced; the sample strip is not deformed, so that the sample strip can be used for the crosslinking degree test, and the utilization rate of sample strips after sampling is improved; the sample strip is not subjected to the external mechanical tensile force, the situation that the test result is affected due to test sample strips undergoing mechanical stress effect is avoided, and the test result can be reflected more objectively and fairly, and accurate parameters are obtained.

Description

technical field [0001] The invention relates to a tool for detecting the degree of cross-linking, in particular to an EVA sample strip peeling device for detecting the degree of cross-linking. Background technique [0002] The degree of cross-linking, also known as the cross-linking index, is used to characterize the degree of cross-linking of polymer chains, usually by cross-linking density or the number-average molecular weight between two adjacent cross-linking points or the number of moles of cross-linking points per cubic centimeter. It means that the degree of cross-linking can be measured by mechanical method or equilibrium swelling ratio method; the rubber with a small degree of cross-linking has better elasticity, and the rubber with a large degree of cross-linking has poor elasticity. If the degree of cross-linking increases, the mechanical strength and hardness will increase. eventually loses its elasticity. With the continuous development of the photovoltaic new...
