How do tensile testing machines test shoes? If the peeling performance of the footwear test, then the peeling is the key to the quality of the shoes, like the past few years, the production of a variety of adhesive shoes, some of the "weeks shoes", "cross-street shoes", many are glue quality and operation Inappropriate, then, how do we do a peel test of leather, following the Haida Xiaobian to understand it.

China's peeling inspection method is to install shoes into the shoe last, clamp it on the machine, peel off the joint between the sole and the upper with a peeling knife, and measure the peeling force as the peeling force, according to the peeling force and the width of the knife edge. Peel strength. There are three main ways to test the peeling force of shoes:

    1. Peel off the top of the shoe from the sole and the upper, and place it on the machine. Divide the whole shoe into several points according to the customer's requirements, measure the peeling force at each point, and then divide the peel strength of each punctuation by each The width of the punctuation gives the peel strength of each point.

  2. Cut the sole of the shoe into the upper of the shoe upper and leave a width of 1~2cm between the side wall of the shoe sole and the upper part of the shoe upper. Generally, the adult shoes have an average of 22 points on the surrounding landmarks, and the children’s shoes are marked with 12 points. If the big bottom wall and the upper part of the joint are lined with a big bottom line, the big bottom line must be removed first. Then the sample is clamped on a pulling machine to measure the peeling force at each point, and the width of the glued width between the large bottom wall and the upper is removed. Peel strength.

    3 , in the preparation of the big end of the shoe wall and the upper adhesive tape to cut the same width of 1cm , measured the peel strength of each point.

      The above is the test method for leather, Haida instrument also responds to GB/T39.3.3-2011 standard requirements, the use of force sensors instead of the old standard using dial gauge look-up table method to obtain the peel force, use the test method data The expression is more scientific. Haida Instrument now recommends two peel strength test machines ; HD-B60B9-S leather shoe peel strength tester, HD-B602 economical pull tester.
