wherein L is the temperature difference displacement of the ceramic tile in the vertical direction, L is the height of the ceramic tile adhered on the wall surface, and Δ TS Alpha is the linear thermal expansion coefficient of the ceramic tile, which is the temperature difference of the plate when the ceramic tile is subjected to extreme temperature during construction and after the ceramic tile is pasted.

Measured bond strength = tensile peak ÷ expanded area. Based on the above test results, the numerical discreteness of the adhesive force of D =10mm, D =15mm, and D =20mm is large, and is no longer adopted. The weight of the porcelain brick with the size of 300mm multiplied by 600mm commonly used in a construction site is about 31.25N/block, D =25mm, the average single-point bonding force of the structural adhesive with H =3mm is 587N >31.25N, D =30mm, the average single-point bonding force of the structural adhesive with H =3mm is 611N >31.25N, and the requirements can be met.
Comparative analysis was performed for D =25mm and D =30 mm: d =25mm, the average bonding force is 587N, and the glue amount is 1473mm for carrying out the high-speed harvest; d =30mm bonding force averaged 611N, and was carried out by 2119mm thick shoots with glue. And (3) comparing the binding power: (611) -587)/587 = 4%; and (3) glue amount comparison: (2119-1473)/1473 = 44%. The adhesive force is improved by 4 percent, and the glue consumption is required to be improved by 44 percent, which is not economical.
And (4) conclusion: after the test, the bonding strength (tensile and shear) can be satisfied by carrying out the thin film dry film.
Considering the flatness error of the wall surface of a construction site, structural adhesive with the diameter D =25mm and the coating thickness H =5mm is respectively coated on each single point of the corner points and the central points (5 single points in total) of the rectangle, and the effect is good after field pasting and suspension test verification.
