Description

Technical Field

[0001] The utility model relates to the technical field of ceramic tile detection sample preparation, in particular to a sample preparation device for detecting the bonding strength of ceramic tile adhesives. Background Technique

[0002] At present, the sample preparation for detecting the bonding strength of ceramic tile adhesives is all manual sample preparation, and there are deviations in the scraping force, angle, final adhesive thickness, and pressing block placement time, resulting in a large discreteness of the test results and unable to reflect the true test results. The current standard describes the sample preparation as follows: Apply a thin layer of adhesive on the concrete slab with a straight-edge trowel, scrape forcefully, then apply a slightly thicker layer of adhesive with a toothed trowel, and comb it with a toothed trowel of 6mm×6mm (center distance 12mm). When holding the toothed trowel, it should be at about 60° to the concrete slab, at a right angle to one side of the concrete slab, and parallelly smeared to the edge of the concrete slab (linear movement). Within the specified time, at least 10 test ceramic tiles (spaced 40mm apart) are placed on the adhesive. For all adhesives, there should be 4 comb bars where the ceramic tiles are placed. Place a (2000±15)g pressing block on each ceramic tile for 30s.

[0003] In the above sample preparation regulations, requirements for force, angle, comb bars, pressing block placement time, and comb bar parallelism are put forward for sample preparation. However, in actual operation, different operators have different implementation degrees of the above requirements, resulting in differences in adhesive thickness and bonding strength.

[0004] The existing technologies are all manual operations, and the main disadvantages are:

[0005] 1. The scraping force cannot be quantified;

[0006] 2. The scraping angle cannot be accurately quantified;

[0007] 3. When combing with a toothed trowel, it is impossible to accurately maintain linear movement, and the comb bars are prone to bending;

[0008] 4. When conducting tests on more than 10 test ceramic tiles simultaneously, the pressing block placement time for different test blocks is prone to exceed the time limit. Content of the Utility Model
