Embodiment 1

[0035] Pour the viscose 20A into the viscose groove 11 of the metal fixture 10. The thickness of the viscose is 5mm. Cut the cylinder body filter material 30 into a rectangle of 300mm*80mm, and fold it in half along the long side to form a "V" shape, that is, " The length of each side of the V" shape is 40mm, and the knuckle angle is 60°. Insert the filter material 30 "V" shape vertically into the viscose 20A that has been poured into the metal fixture 10 . After standing for 24 hours, the viscose 20A is completely cured. Fix the metal clamp 10 on the tensile strength machine with a bolt, clamp the filter material 30 with the clamp of the strength machine, test the tensile properties at a pulling speed of 100mm / min and record the fracture form. Repeat for 3 samples. The test structure of the 3 samples is recorded as follows:

Embodiment 2

[0038] After mixing the two-component viscose 20B evenly in proportion, pour it into the viscose groove 11 of the metal fixture 10. The thickness of the viscose 20B is 5mm. Cut the cylinder body filter material 30 into a rectangle of 300mm*80mm, and align it along the long side Fold in half into a "V" shape, that is, the length of each side of the "V" shape is 40mm, and the folding angle is 60°. Insert the "V" shaped side of the filter material 30 vertically into the viscose 20 that has been poured into the metal fixture 10 . After standing for 8 hours, the viscose 20B is completely cured. Fix the metal clamp 10 on the tensile strength machine with a bolt, clamp the filter material 30 with the clamp of the strength machine, test the tensile properties at a pulling speed of 100mm / min and record the fracture form. Repeat for 3 samples. The test structure of the 3 samples is recorded as follows:

Embodiment 3

[0041] Pour the viscose 20C into the viscose groove 11 of the metal fixture 10. The thickness of the viscose 20C is 7mm. Cut the cylinder body filter material 30 into a rectangle of 300mm*80mm, and fold it in half along the long side to form a "V" shape, that is The length of each side of the "V" shape is 40mm, and the folding angle is 60°. Insert the filter material 30 "V" shape vertically into the viscose 20C that has been poured into the metal jig 10 . After standing for 12 hours, the viscose 20C is completely cured. Fix the metal clamp 10 on the tensile strength machine with a bolt, clamp the filter material 30 with the clamp of the strength machine, test the tensile properties at a pulling speed of 100mm / min and record the fracture form. Repeat for 3 samples. The test structure of the 3 samples is recorded as follows:

Abstract

The invention discloses a test method for an adhesive force of filter drum end cover adhesive. The method comprises the following steps: step 1: pouring adhesive into a horizontal adhesive channel of a metal clamp; step 2: cutting a filter material on a filter drum body, ensuring at least one edge of the cut filter material to be a straight edge, and bending the filter material along the straight edge, wherein the straight edge is disposed on a same plane; step 3: vertically inserting the straight edge of the bent filter material into an adhesive layer poured into the adhesive channel until the straight edge completely contacts the metal clamp, so that the filter material is perpendicular to the bottom surface of the adhesive channel of the metal clamp; and step 4: after the adhesive is completely solidified, fixing the metal clamp on a tensile strength machine, clamping the filter material, pneumatically stretching the tensile strength machine, and testing the tensile performance. By using the test method of the invention, the adhesive force of the filter drum end cover adhesive can be intuitively reflected.

Description

technical field [0001] The invention relates to a method for testing the adhesive force, in particular to a method for testing the adhesive force of the filter cartridge end cover. Background technique [0002] The upper and lower end caps of the filter cartridge are structures that bear the weight of the filter cartridge. The upper end cap connects the filter cartridge and the flower plate to bear the weight of the filter cartridge itself, and the lower end cap directly bears the impact of the pulse cleaning airflow. The upper and lower end caps of the filter cartridge are connected to the filter cartridge body with viscose. If the adhesive force is not strong enough, the upper and lower end caps are easy to fall off due to force, resulting in damage to the filter cartridge. The body of the filter cartridge is made of polymer material, and the end cap is usually made of metal material. The two are vertically bonded together in a "T" shape through glue. The glue layer is gen...
