Embodiment 1

[0035] Pour the glue 20A into the glue tank 11 of the metal fixture 10, the thickness of the glue is 5mm, cut the filter material 30 of the cylinder body into a 300mm*80mm rectangle, and fold it in half along the long side into a "V" shape, that is, " Each side of the V" shape is 40mm long and the bend angle is 60°. Vertically insert the "V"-shaped edge of the filter material 30 into the glue 20A that has been poured into the metal fixture 10. After standing for 24 hours, the adhesive 20A is completely cured. The metal clamp 10 is fixed on the tensile strength machine with a pin, the filter material 30 is clamped with the clamp of the strength machine, and the tensile performance is tested at a pulling speed of 100 mm / min and the fracture mode is recorded. Repeat 3 samples. The test structure records of 3 samples are as follows:

Embodiment 2

[0038] After mixing the two-component viscose 20B evenly in proportion, pour it into the glue tank 11 of the metal fixture 10. The thickness of the viscose 20B is 5mm. Cut the filter material 30 into a 300mm*80mm rectangle and align it along the long side. Half-folded into a "V" shape, that is, each side of the "V" shape is 40mm long and the bend angle is 60°. Vertically insert the "V"-shaped edge of the filter material 30 into the glue 20 that has been poured into the metal fixture 10. After standing for 8 hours, the adhesive 20B was completely cured. The metal clamp 10 is fixed on the tensile strength machine with a pin, the filter material 30 is clamped with the clamp of the strength machine, and the tensile performance is tested at a pulling speed of 100 mm / min and the fracture mode is recorded. Repeat 3 samples. The test structure records of 3 samples are as follows:

Embodiment 3

[0041] Pour the viscose 20C into the glue tank 11 of the metal fixture 10, the thickness of the viscose 20C is 7mm, cut the filter material 30 of the cylinder body into a 300mm*80mm rectangle, and fold it in half along the long side into a "V" shape, namely Each side of the "V" shape is 40mm long, and the bend angle is 60°. Vertically insert the "V"-shaped edge of the filter material 30 into the glue 20C that has been poured into the metal fixture 10. After standing for 12 hours, the adhesive 20C is completely cured. The metal clamp 10 is fixed on the tensile strength machine with a pin, the filter material 30 is clamped with the clamp of the strength machine, and the tensile performance is tested at a pulling speed of 100 mm / min and the fracture mode is recorded. Repeat 3 samples. The test structure records of 3 samples are 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 adhesive force, in particular to a method for testing adhesive force of filter cartridge end caps. Background technique [0002] The upper and lower end caps of the filter cartridge are the structure to bear the weight of the filter cartridge. The upper end cover connects the filter cartridge and the flower plate to bear the weight of the filter cartridge, and the lower end cover directly bears the impact of the pulse cleaning airflow. The upper and lower end caps of the filter cartridge are connected with the body of the filter cartridge by viscose. If the adhesive strength is not strong enough, the upper and lower end caps will easily fall off due to the 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 a metal material. The two are vertically bonded together in a "T" shape with glue. The glue layer generally covers the ...
