The invention discloses a method for detecting the strength of polyethylene products, the steps of which are: before using the invention to detect the strength of polyethylene products, the operation of the device is checked, the operator uses a fixing mechanism to fix the polyethylene pipe, and the operator Use the processing mechanism to heat or refrigerate the surface of the polyethylene pipe to detect the surface strength of the polyethylene pipe under this condition, and use the vibration mechanism to process the polyethylene pipe to match the polyethylene pipe under heating or refrigeration. surface strength. In this method, the gas is filled into the fixed airbag and the extruded airbag on the hollow shaft by setting an air pump, and at this time, the fixed airbag and the extruded airbag are expanded to fix the polyethylene pipe, and the trapezoidal shape of the inner wall of the fixed airbag is fixed. Rubber blocks are used to increase the friction between the outer wall of the polyethylene pipe and ensure the firmness of the polyethylene pipe.

The invention provides a digitally displayed automatic adhesive force instrument. The adhesive force instrument comprises a control part and a mechanical part, wherein a motor of the control part is fixed on a cross beam of a supporting framework; a rotating shaft of the motor is connected with one end of a steel wire; the steel wire hangs down after wrapping over a pulley fixed on the cross beam of the supporting framework along the cross beam of the supporting framework, and the other end of the steel wire is connected with one end of a steel wire joint connected with a drawing force sensor; the other end of the steel wire joint is connected with a preloading block through a soft drawn wire; a test sample box fixed on a test sample box base is arranged below the preloading block; the steel wire, the drawing force sensor, the preloading block and the test sample box are arranged on the same axial line; the motor is electrically connected with a control box body; and the drawing force sensor is electrically connected with the control box body. The digitally displayed automatic adhesive force instrument has the advantages that: due to the structure of the instrument, the test steps are reduced, the work of weighing steel balls is reduced, a loading rate and a stress on a test sample are uniform and test data acquisition is more stable and accurate, so that a test result is closer to a real value and the test efficiency is improved greatly; therefore, the digitally displayed automatic adhesive force instrument is applicable to adhesive force measurement of various soils.
